Description

UPLINK COMMUNICATIONS WITH MULTIPLE CODEWORDS

BACKGROUND Technical Field

The present disclosure generally relates to communication systems, and more particularly, to uplink communications using multiple codewords.

Introduction

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR) . 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT) ) , and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB) , massive machine type communications (mMTC) , and ultra-reliable low latency communications (URLLC) . Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies.

DETAILED DESCRIPTION

The detailed description set forth below in connection with the appended drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details for the purpose of providing a thorough understanding of various concepts. However, it will be apparent to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

Certain aspects are directed to uplink communications using multiple codewords or transport blocks (TBs) . For example, uplink multiple-input multiple-output (MIMO) operations may support four or more layers per UE wherein eight concurrent transmitting antennas may be enabled at the UE. As a result of the UE supporting four or more layers, the UE may also support up to two codewords per uplink transmission. In other words, the UE may transmit via two separate TBs in a single uplink transmission.

A network entity may configure the UE (e.g., via downlink control information (DCI) ) such that each separate TB has its own modulation and coding scheme (MCS) , new data indicator (NDI) , redundancy version identifier (RVID) , etc. Thus, a first TB (e.g., TB1) and a second TB (e.g., TB2) may be separately controlled by the network entity, and even enabled/disabled. In some examples, the network entity may configure the UE to operate using two TBs via RRC configuration messaging.

In some examples, a network entity may transmit a DCI that grants the UE resources for an uplink transmission, where the DCI includes a channel state information (CSI) request configured to trigger a CSI report from the UE. Accordingly, the UE may measure CSI reference signals (CSI-RSs) received from the network entity, generate a CSI report based on the measurements, and multiplex the CSI report in the uplink transmission. However, if the network entity disables one or both of the TBs, problems may arise with how the UE will transmit data and/or uplink control information (UCI) (e.g., hybrid automatic repeat request (HARQ) acknowledgment (ACK) and/or CSI report) to the network entity.

In certain aspects, the network entity may transmit a DCI to the UE indicating that one of the two TBs is disabled, and also indicating that the uplink transmission can carry data. In such an example, the UCI and the data may be multiplexed into the single remaining TB. In such an example, the UE may determine a number of resources it can use for transmission of the UCI via the remaining TB (e.g., the UE may determine a number of coded modulation symbols per layer for transmission of the UCI via the TB) . In some examples, the number of resources may be determined based at least in part on a code block size of the TB being used for the uplink transmission (e.g., code block size of the TB in which the UCI is multiplexed on) .

In certain aspects, the network entity may transmit a DCI to the UE indicating that both of the two TBs is disabled. For example, the DCI may grant an uplink transmission and also indicate that no data is to be transmitted with the uplink transmission, thereby causing both TBs to be disabled. Thus, the UE may need to determine which TB it can use to transmit a UCI (e.g., control information) . In such an example, the UE may be preconfigured to use a particular TB for uplink transmission of the UCI. For example, the UE may be preconfigured according to a wireless communication standard (e.g., 3rd Generation Partnership Project (3GPP) standard) or a factory setting. In another example, the UE may select one of the two TBs to use for the uplink transmission based on which of the two TBs has a higher MCS. As discussed, the DCI may separately configure communication parameters for each of the TBs. Thus, each TB may have a different or same MCS. If the MCSs are different between the two TBs, then the UE may perform the uplink transmission using the TB with the higher MCS. If the two TBs are associated with the same MCS, then the UE may select one of the TBs for the uplink transmission. The selection may be based on a pre-configuration (e.g., a wireless communication standard or factory setting) , a configuration provided to the UE via the network entity (e.g., via an RRC configuration message) .

Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as “elements” ) . These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

By way of example, an element, or any portion of an element, or any combination of elements may be implemented as a “processing system” that includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs) , central processing units (CPUs) , application processors, digital signal processors (DSPs) , reduced instruction set computing (RISC) processors, systems on a chip (SoC) , baseband processors, field programmable gate arrays (FPGAs) , programmable logic devices (PLDs) , state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure. One or more processors in the processing system may execute software. Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software components, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

Accordingly, in one or more example embodiments, the functions described may be implemented in hardware, software, or any combination thereof. If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that can be accessed by a computer. By way of example, and not limitation, such computer-readable media can comprise a random-access memory (RAM) , a read-only memory (ROM) , an electrically erasable programmable ROM (EEPROM) , optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

FIG. 1 is a diagram illustrating an example of a wireless communications system and an access network 100. The wireless communications system (also referred to as a wireless wide area network (WWAN) ) includes base stations 102, user equipment (s) (UE) 104, an Evolved Packet Core (EPC) 160, and another core network 190 (e.g., a 5G Core (5GC) ) . The base stations 102 may include macrocells (high power cellular base station) and/or small cells (low power cellular base station) . The macrocells include base stations. The small cells include femtocells, picocells, and microcells.

The base stations 102 configured for 4G Long Term Evolution (LTE) (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN) ) may interface with the EPC 160 through first backhaul links 132 (e.g., S1 interface) . The base stations 102 configured for 5G New Radio (NR) (collectively referred to as Next Generation RAN (NG-RAN) ) may interface with core network 190 through second backhaul links 184. In addition to other functions, the base stations 102 may perform one or more of the following functions: transfer of user data, radio channel ciphering and deciphering, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity) , inter-cell interference coordination, connection setup and release, load balancing, distribution for non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, Multimedia Broadcast Multicast Service (MBMS) , subscriber and equipment trace, RAN information management (RIM) , paging, positioning, and delivery of warning messages. The base stations 102 may communicate directly or indirectly (e.g., through the EPC 160 or core network 190) with each other over third backhaul links 134 (e.g., X2 interface) . The first backhaul links 132, the second backhaul links 184, and the third backhaul links 134 may be wired or wireless.

The base stations 102 may wirelessly communicate with the UEs 104. Each of the base stations 102 may provide communication coverage for a respective geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, the small cell 102' may have a coverage area 110' that overlaps the coverage area 110 of one or more macro base stations 102. A network that includes both small cell and macrocells may be known as a heterogeneous network. A heterogeneous network may also include Home Evolved Node Bs (eNBs) (HeNBs) , which may provide service to a restricted group known as a closed subscriber group (CSG) . The communication links 120 between the base stations 102 and the UEs 104 may include uplink (UL) (also referred to as reverse link) transmissions from a UE 104 to a base station 102 and/or downlink (DL) (also referred to as forward link) transmissions from a base station 102 to a UE 104. The communication links 120 may use multiple-input and multiple-output (MIMO) antenna technology, including spatial multiplexing, beamforming, and/or transmit diversity. The communication links may be through one or more carriers. The base stations 102 /UEs 104 may use spectrum up to Y megahertz (MHz) (e.g., 5, 10, 15, 20, 100, 400, etc. MHz) bandwidth per carrier allocated in a carrier aggregation of up to a total of Yx MHz (x component carriers) used for transmission in each direction. The carriers may or may not be adjacent to each other. Allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL than for UL) . The component carriers may include a primary component carrier and one or more secondary component carriers. A primary component carrier may be referred to as a primary cell (PCell) and a secondary component carrier may be referred to as a secondary cell (SCell) .

Certain UEs 104 may communicate with each other using device-to-device (D2D) communication link 158. The D2D communication link 158 may use the DL/UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH) , a physical sidelink discovery channel (PSDCH) , a physical sidelink shared channel (PSSCH) , and a physical sidelink control channel (PSCCH) . D2D communication may be through a variety of wireless D2D communications systems, such as for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

The wireless communications system may further include a Wi-Fi access point (AP) 150 in communication with Wi-Fi stations (STAs) 152 via communication links 154, e.g., in a 5 gigahertz (GHz) unlicensed frequency spectrum or the like. When communicating in an unlicensed frequency spectrum, the STAs 152 /AP 150 may perform a clear channel assessment (CCA) prior to communicating in order to determine whether the channel is available.

The small cell 102' may operate in a licensed and/or an unlicensed frequency spectrum. When operating in an unlicensed frequency spectrum, the small cell 102' may employ NR and use the same unlicensed frequency spectrum (e.g., 5 GHz, or the like) as used by the Wi-Fi AP 150. The small cell 102', employing NR in an unlicensed frequency spectrum, may boost coverage to and/or increase capacity of the access network.

The electromagnetic spectrum is often subdivided, based on frequency/wavelength, into various classes, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz –7.125 GHz) and FR2 (24.25 GHz –52.6 GHz) . The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

With the above aspects in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like if used herein may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like if used herein may broadly represent frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

A base station 102, whether a small cell 102' or a large cell (e.g., macro base station) , may include and/or be referred to as an eNB, gNodeB (gNB) , or another type of base station. Some base stations, such as gNB 180 may operate in a traditional sub 6 GHz spectrum, in millimeter wave frequencies, and/or near millimeter wave frequencies in communication with the UE 104. When the gNB 180 operates in millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. The millimeter wave base station 180 may utilize beamforming 182 with the UE 104 to compensate for the path loss and short range. The base station 180 and the UE 104 may each include a plurality of antennas, such as antenna elements, antenna panels, and/or antenna arrays to facilitate the beamforming.

The base station 180 may transmit a beamformed signal to the UE 104 in one or more transmit directions 182'. The UE 104 may receive the beamformed signal from the base station 180 in one or more receive directions 182” . The UE 104 may also transmit a beamformed signal to the base station 180 in one or more transmit directions. The base station 180 may receive the beamformed signal from the UE 104 in one or more receive directions. The base station 180 /UE 104 may perform beam training to determine the best receive and transmit directions for each of the base station 180 /UE 104. The transmit and receive directions for the base station 180 may or may not be the same. The transmit and receive directions for the UE 104 may or may not be the same.

The EPC 160 may include a Mobility Management Entity (MME) 162, other MMEs 164, a Serving Gateway 166, an MBMS Gateway 168, a Broadcast Multicast Service Center (BM-SC) 170, and a Packet Data Network (PDN) Gateway 172. The MME 162 may be in communication with a Home Subscriber Server (HSS) 174. The MME 162 is the control node that processes the signaling between the UEs 104 and the EPC 160. Generally, the MME 162 provides bearer and connection management. All user Internet protocol (IP) packets are transferred through the Serving Gateway 166, which itself is connected to the PDN Gateway 172. The PDN Gateway 172 provides UE IP address allocation as well as other functions. The PDN Gateway 172 and the BM-SC 170 are connected to the IP Services 176. The IP Services 176 may include the Internet, an intranet, an IP Multimedia Subsystem (IMS) , a PS Streaming Service, and/or other IP services. The BM-SC 170 may provide functions for MBMS user service provisioning and delivery. The BM-SC 170 may serve as an entry point for content provider MBMS transmission, may be used to authorize and initiate MBMS Bearer Services within a public land mobile network (PLMN) , and may be used to schedule MBMS transmissions. The MBMS Gateway 168 may be used to distribute MBMS traffic to the base stations 102 belonging to a Multicast Broadcast Single Frequency Network (MBSFN) area broadcasting a particular service, and may be responsible for session management (start/stop) and for collecting eMBMS related charging information.

The core network 190 may include a Access and Mobility Management Function (AMF) 192, other AMFs 193, a Session Management Function (SMF) 194, and a User Plane Function (UPF) 195. The AMF 192 may be in communication with a Unified Data Management (UDM) 196. The AMF 192 is the control node that processes the signaling between the UEs 104 and the core network 190. Generally, the AMF 192 provides Quality of Service (QoS) flow and session management. All user IP packets are transferred through the UPF 195. The UPF 195 provides UE IP address allocation as well as other functions. The UPF 195 is connected to the IP Services 197. The IP Services 197 may include the Internet, an intranet, an IMS, a Packet Switch (PS) Streaming Service, and/or other IP services.

The base station may include and/or be referred to as a gNB, Node B, eNB, an access point, a base transceiver station, a radio base station, a radio transceiver, a transceiver function, a basic service set (BSS) , an extended service set (ESS) , a transmit reception point (TRP) , or some other suitable terminology. The base station 102 provides an access point to the EPC 160 or core network 190 for a UE 104. Examples of UEs 104 include a cellular phone, a smart phone, a session initiation protocol (SIP) phone, a laptop, a personal digital assistant (PDA) , a satellite radio, a global positioning system, a multimedia device, a video device, a digital audio player (e.g., MP3 player) , a camera, a game console, a tablet, a smart device, a wearable device, a vehicle, an electric meter, a gas pump, a large or small kitchen appliance, a healthcare device, an implant, a sensor/actuator, a display, or any other similar functioning device. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meter, gas pump, toaster, vehicles, heart monitor, etc. ) . The UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology. A wireless node may comprise a UE, a base station, or a network entity.

Referring again to FIG. 1, in certain aspects, the UE 104 may include a transport block selection module 198 configured to obtain a first message configured to: grant an uplink transmission of control information, and disable a first transmission block (TB) of two TBs used by the UE for uplink transmissions; and output for transmission the uplink transmission via a second TB of the two TBs, wherein the control information is output for transmission via resources of the second TB based at least on a communication parameter of the second TB.

Referring again to FIG. 1, in certain aspects, the base station 102/180 may include a transport block selection module 199 configured to output, for transmission to a user equipment (UE) , a first message configured to: grant an uplink transmission of control information, and disable a first transmission block (TB) of two TBs used by the UE for uplink transmissions; and obtain, from the UE, the uplink transmission via a second TB of the two TBs, wherein the control information is obtained via resources of the second TB based at least on a communication parameter of the second TB.

FIG. 2A is a diagram 200 illustrating an example of a first subframe within a 5G NR frame structure. FIG. 2B is a diagram 230 illustrating an example of DL channels within a 5G NR subframe. FIG. 2C is a diagram 250 illustrating an example of a second subframe within a 5G NR frame structure. FIG. 2D is a diagram 280 illustrating an example of UL channels within a 5G NR subframe. The 5G NR frame structure may be frequency division duplexed (FDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for either DL or UL, or may be time division duplexed (TDD) in which for a particular set of subcarriers (carrier system bandwidth) , subframes within the set of subcarriers are dedicated for both DL and UL. In the examples provided by FIGs. 2A, 2C, the 5G NR frame structure is assumed to be TDD, with subframe 4 being configured with slot format 28 (with mostly DL) , where D is DL, U is UL, and F is flexible for use between DL/UL, and subframe 3 being configured with slot format 34 (with mostly UL) . While subframes 3, 4 are shown with slot formats 34, 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0, 1 are all DL, UL, respectively. Other slot formats 2-61 include a mix of DL, UL, and flexible symbols. UEs are configured with the slot format (dynamically through DL control information (DCI) , or semi-statically/statically through radio resource control (RRC) signaling) through a received slot format indicator (SFI) . Note that the description infra applies also to a 5G NR frame structure that is TDD.

Other wireless communication technologies may have a different frame structure and/or different channels. A frame, e.g., of 10 milliseconds (ms) , may be divided into 10 equally sized subframes (1 ms) . Each subframe may include one or more time slots. Subframes may also include mini-slots, which may include 7, 4, or 2 symbols. Each slot may include 7 or 14 symbols, depending on the slot configuration. For slot configuration 0, each slot may include 14 symbols, and for slot configuration 1, each slot may include 7 symbols. The symbols on DL may be cyclic prefix (CP) orthogonal frequency-division multiplexing (OFDM) (CP-OFDM) symbols. The symbols on UL may be CP-OFDM symbols (for high throughput scenarios) or discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbols (also referred to as single carrier frequency-division multiple access (SC-FDMA) symbols) (for power limited scenarios; limited to a single stream transmission) . The number of slots within a subframe is based on the slot configuration and the numerology. For slot configuration 0, different numerologies μ 0 to 4 allow for 1, 2, 4, 8, and 16 slots, respectively, per subframe. For slot configuration 1, different numerologies 0 to 2 allow for 2, 4, and 8 slots, respectively, per subframe. Accordingly, for slot configuration 0 and numerology μ, there are 14 symbols/slot and 2^μ slots/subframe. The subcarrier spacing and symbol length/duration are a function of the numerology. The subcarrier spacing may be equal to 2^μ*15 kilohertz (kHz) , where μ is the numerology 0 to 4. As such, the numerology μ=0 has a subcarrier spacing of 15 kHz and the numerology μ=4 has a subcarrier spacing of 240 kHz. The symbol length/duration is inversely related to the subcarrier spacing. FIGs. 2A-2D provide an example of slot configuration 0 with 14 symbols per slot and numerology μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a set of frames, there may be one or more different bandwidth parts (BWPs) (see FIG. 2B) that are frequency division multiplexed. Each BWP may have a particular numerology.

A resource grid may be used to represent the frame structure. Each time slot includes a resource block (RB) (also referred to as physical RBs (PRBs) ) that extends 12 consecutive subcarriers. The resource grid is divided into multiple resource elements (REs) . The number of bits carried by each RE depends on the modulation scheme.

As illustrated in FIG. 2A, some of the REs carry reference (pilot) signals (RS) for the UE.The RS may include demodulation RS (DM-RS) (indicated as R_x for one particular configuration, where 100x is the port number, but other DM-RS configurations are possible) and channel state information reference signals (CSI-RS) for channel estimation at the UE. The RS may also include beam measurement RS (BRS) , beam refinement RS (BRRS) , and phase tracking RS (PT-RS) .

FIG. 2B illustrates an example of various DL channels within a subframe of a frame. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs) , each CCE including nine RE groups (REGs) , each REG including four consecutive REs in an OFDM symbol. A PDCCH within one BWP may be referred to as a control resource set (CORESET) . Additional BWPs may be located at greater and/or lower frequencies across the channel bandwidth. A primary synchronization signal (PSS) may be within symbol 2 of particular subframes of a frame. The PSS is used by a UE 104 to determine subframe/symbol timing and a physical layer identity. A secondary synchronization signal (SSS) may be within symbol 4 of particular subframes of a frame. The SSS is used by a UE to determine a physical layer cell identity group number and radio frame timing. Based on the physical layer identity and the physical layer cell identity group number, the UE can determine a physical cell identifier (PCI) . Based on the PCI, the UE can determine the locations of the aforementioned DM-RS. The physical broadcast channel (PBCH) , which carries a master information block (MIB) , may be logically grouped with the PSS and SSS to form a synchronization signal (SS) /PBCH block (also referred to as SS block (SSB) ) . The MIB provides a number of RBs in the system bandwidth and a system frame number (SFN) . The physical downlink shared channel (PDSCH) carries user data, broadcast system information not transmitted through the PBCH such as system information blocks (SIBs) , and paging messages.

As illustrated in FIG. 2C, some of the REs carry DM-RS (indicated as R for one particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may transmit DM-RS for the physical uplink control channel (PUCCH) and DM-RS for the physical uplink shared channel (PUSCH) . The PUSCH DM-RS may be transmitted in the first one or two symbols of the PUSCH. The PUCCH DM-RS may be transmitted in different configurations depending on whether short or long PUCCHs are transmitted and depending on the particular PUCCH format used. The UE may transmit sounding reference signals (SRS) . The SRS may be transmitted in the last symbol of a subframe. The SRS may have a comb structure, and a UE may transmit SRS on one of the combs. The SRS may be used by a base station for channel quality estimation to enable frequency-dependent scheduling on the UL.

FIG. 2D illustrates an example of various UL channels within a subframe of a frame. The PUCCH may be located as indicated in one configuration. The PUCCH carries uplink control information (UCI) , such as scheduling requests, a channel quality indicator (CQI) , a precoding matrix indicator (PMI) , a rank indicator (RI) , and hybrid automatic repeat request (HARQ) acknowledgement (ACK) /non-acknowledgement (NACK) feedback. The PUSCH carries data, and may additionally be used to carry a buffer status report (BSR) , a power headroom report (PHR) , and/or UCI.

FIG. 3 is a block diagram of a base station 310 in communication with a UE 350 in an access network. In the DL, IP packets from the EPC 160 may be provided to a controller/processor 375. The controller/processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller/processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIBs) , RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release) , inter radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression /decompression, security (ciphering, deciphering, integrity protection, integrity verification) , and handover support functions; RLC layer functionality associated with the transfer of upper layer packet data units (PDUs) , error correction through ARQ, concatenation, segmentation, and reassembly of RLC service data units (SDUs) , re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs) , demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

The transmit (TX) processor 316 and the receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1, which includes a physical (PHY) layer, may include error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, interleaving, rate matching, mapping onto physical channels, modulation/demodulation of physical channels, and MIMO antenna processing. The TX processor 316 handles mapping to signal constellations based on various modulation schemes (e.g., binary phase-shift keying (BPSK) , quadrature phase-shift keying (QPSK) , M-phase-shift keying (M-PSK) , M-quadrature amplitude modulation (M-QAM) ) . The coded and modulated symbols may then be split into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and/or frequency domain, and then combined together using an Inverse Fast Fourier Transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially precoded to produce multiple spatial streams. Channel estimates from a channel estimator 374 may be used to determine the coding and modulation scheme, as well as for spatial processing. The channel estimate may be derived from a reference signal and/or channel condition feedback transmitted by the UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate an RF carrier with a respective spatial stream for transmission.

At the UE 350, each receiver 354RX receives a signal through its respective antenna 352. Each receiver 354RX recovers information modulated onto an RF carrier and provides the information to the receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 may perform spatial processing on the information to recover any spatial streams destined for the UE 350. If multiple spatial streams are destined for the UE 350, they may be combined by the RX processor 356 into a single OFDM symbol stream. The RX processor 356 then converts the OFDM symbol stream from the time-domain to the frequency domain using a Fast Fourier Transform (FFT) . The frequency domain signal comprises a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier, and the reference signal, are recovered and demodulated by determining the most likely signal constellation points transmitted by the base station 310. These soft decisions may be based on channel estimates computed by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals that were originally transmitted by the base station 310 on the physical channel. The data and control signals are then provided to the controller/processor 359, which implements layer 3 and layer 2 functionality.

The controller/processor 359 can be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer-readable medium. In the UL, the controller/processor 359 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller/processor 359 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.

Similar to the functionality described in connection with the DL transmission by the base station 310, the controller/processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIBs) acquisition, RRC connections, and measurement reporting; PDCP layer functionality associated with header compression /decompression, and security (ciphering, deciphering, integrity protection, integrity verification) ; RLC layer functionality associated with the transfer of upper layer PDUs, error correction through ARQ, concatenation, segmentation, and reassembly of RLC SDUs, re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

Channel estimates derived by a channel estimator 358 from a reference signal or feedback transmitted by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes, and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antenna 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a respective spatial stream for transmission.

The UL transmission is processed at the base station 310 in a manner similar to that described in connection with the receiver function at the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

The controller/processor 375 can be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer-readable medium. In the UL, the controller/processor 375 provides demultiplexing between transport and logical channels, packet reassembly, deciphering, header decompression, control signal processing to recover IP packets from the UE 350. IP packets from the controller/processor 375 may be provided to the EPC 160. The controller/processor 375 is also responsible for error detection using an ACK and/or NACK protocol to support HARQ operations.

FIG. 4 is a block diagram illustrating an example disaggregated base station 400 architecture. The disaggregated base station 400 architecture may include one or more CUs 410 that can communicate directly with a core network 420 via a backhaul link, or indirectly with the core network 420 through one or more disaggregated base station units (such as a near real-time (RT) RIC 425 via an E2 link, or a non-RT RIC 415 associated with a service management and orchestration (SMO) Framework 405, or both) . A CU 410 may communicate with one or more DUs 430 via respective midhaul links, such as an F1 interface. The DUs 430 may communicate with one or more RUs 440 via respective fronthaul links. The RUs 440 may communicate with respective UEs 104 via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be simultaneously served by multiple RUs 440. As used herein, a network entity may correspond to a base station or to a disaggregated aspect (e.g., CU/DU/RU, etc. ) of the base station.

Each of the units, i.e., the CUs 410, the DUs 430, the RUs 440, as well as the near-RT RICs 425, the non-RT RICs 415 and the SMO framework 405, may include one or more interfaces or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmission medium. Each of the units, or an associated processor or controller providing instructions to the communication interfaces of the units, can be configured to communicate with one or more of the other units via the transmission medium. For example, the units can include a wired interface configured to receive or transmit signals over a wired transmission medium to one or more of the other units. Additionally, the units can include a wireless interface, which may include a receiver, a transmitter or transceiver (such as a radio frequency (RF) transceiver) , configured to receive or transmit signals, or both, over a wireless transmission medium to one or more of the other units.

In some aspects, the CU 410 may host higher layer control functions. Such control functions can include radio resource control (RRC) , packet data convergence protocol (PDCP) , service data adaptation protocol (SDAP) , or the like. Each control function can be implemented with an interface configured to communicate signals with other control functions hosted by the CU 410. The CU 410 may be configured to handle user plane functionality (i.e., central unit –user plane (CU-UP) ) , control plane functionality (i.e., central unit –control plane (CU-CP) ) , or a combination thereof. In some implementations, the CU 410 can be logically split into one or more CU-UP units and one or more CU-CP units. The CU-UP unit can communicate bidirectionally with the CU-CP unit via an interface, such as the E1 interface when implemented in an O-RAN configuration. The CU 410 can be implemented to communicate with the DU 430, as necessary, for network control and signaling.

The DU 430 may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs 440. In some aspects, the DU 430 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, or the like) depending, at least in part, on a functional split, such as those defined by the 3^rd Generation Partnership Project (3GPP) . In some aspects, the DU 430 may further host one or more low PHY layers. Each layer (or module) can be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 430, or with the control functions hosted by the CU 410.

Lower-layer functionality can be implemented by one or more RUs 440. In some deployments, an RU 440, controlled by a DU 430, may correspond to a logical node that hosts RF processing functions, or low-PHY layer functions (such as performing fast Fourier transform (FFT) , inverse FFT (iFFT) , digital beamforming, physical random access channel (PRACH) extraction and filtering, or the like) , or both, based at least in part on the functional split, such as a lower layer functional split. In such an architecture, the RU (s) 440 can be implemented to handle over the air (OTA) communication with one or more UEs 104. In some implementations, real-time and non-real-time aspects of control and user plane communication with the RU (s) 440 can be controlled by the corresponding DU 430. In some scenarios, this configuration can enable the DU (s) 430 and the CU 410 to be implemented in a cloud-based RAN architecture, such as a virtual RAN (vRAN) architecture.

The SMO Framework 405 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 405 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operations and maintenance interface (such as an O1 interface) . For virtualized network elements, the SMO framework 405 may be configured to interact with a cloud computing platform (such as an open cloud (O-cloud) 490) to perform network element life cycle management (such as to instantiate virtualized network elements) via a cloud computing platform interface (such as an O2 interface) . Such virtualized network elements can include, but are not limited to, CUs 410, DUs 430, RUs 440 and near-RT RICs 425. In some implementations, the SMO framework 405 can communicate with a hardware aspect of a 4G RAN, such as an open eNB (O-eNB) 411, via an O1 interface. Additionally, in some implementations, the SMO Framework 405 can communicate directly with one or more RUs 440 via an O1 interface. The SMO framework 405 also may include the non-RT RIC 415 configured to support functionality of the SMO Framework 405.

The non-RT RIC 415 may be configured to include a logical function that enables non-real-time control and optimization of RAN elements and resources, artificial intelligence/machine learning (AI/ML) workflows including model training and updates, or policy-based guidance of applications/features in the near-RT RIC 425. The non-RT RIC 415 may be coupled to or communicate with (such as via an A1 interface) the near-RT RIC 425. The near-RT RIC 425 may be configured to include a logical function that enables near-real-time control and optimization of RAN elements and resources via data collection and actions over an interface (such as via an E2 interface) connecting one or more CUs 410, one or more DUs 430, or both, as well as an O-eNB, with the near-RT RIC 425.

In some implementations, to generate AI/ML models to be deployed in the near-RT RIC 425, the non-RT RIC 415 may receive parameters or external enrichment information from external servers. Such information may be utilized by the near-RT RIC 425 and may be received at the SMO Framework 405 or the non-RT RIC 415 from non-network data sources or from network functions. In some examples, the non-RT RIC 415 or the near-RT RIC 425 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 415 may monitor long-term trends and patterns for performance and employ AI/ML models to perform corrective actions through the SMO Framework 405 (such as reconfiguration via O1) or via creation of RAN management policies (such as A1 policies) .

At least one of the TX processor 368, the RX processor 356, and the controller/processor 359 may be configured to perform aspects in connection with 198 of FIG. 1.

At least one of the TX processor 316, the RX processor 370, and the controller/processor 375 may be configured to perform aspects in connection with 198 of FIG. 1.

Examples of Uplink Communications by UE Configured with Two Transmit Blocks (TBs)

FIG. 5 is a call-flow diagram illustrating example communications 500 between a UE 104 and a network entity 102/180. In this example, the UE 104 may be configured to support uplink MIMO transmission by enabling up to eight concurrent transmitting antennas at the UE 104. The UE 104 may also be configured to support up to two codewords (e.g., TBs) per uplink transmission.

At an optional first communication 502, the network entity 102 may transmit configuration information to the UE 104. The configuration information may enable the UE 104 to use two TBs for uplink communications (e.g., PUSCH) . In some examples, the configuration information may provide the UE 104 with a default TB to use, or instructions for how the UE is to select a TB, if one or more of the two UE-supported TBs are disabled.

In a second communication 504, the network entity 102 may transmit signaling to the UE 104. The signaling may be a DCI message or any suitable communication format. The transmitted signaling may provide the UE 104 with an uplink grant scheduling the UE 104 for uplink transmission via uplink resources (e.g., PUSCH resources) .

The signaling may also configure the UE 104 to perform channel measurements prior to the uplink resources and provide a report via the uplink resources (e.g., aperiodic CSI (A-CSI) reporting) . For example, the network entity 102 may transmit a DCI that schedules an uplink transmission and triggers an A-CSI report multiplexed with the uplink transmission.

The signaling may also include an indication of: whether one or both of the TBs used by the UE 104 for uplink transmissions are enabled or disabled for the scheduled uplink communication, and whether the UE 104 can transmit data via the scheduled uplink transmission. For example, the DCI may include a field (e.g., a 1-bit field) indicating whether the scheduled uplink transmission can include data or just control information (e.g., UCI) . It should be noted that the UCI may include HARQ ACK/NACK and/or a CSI report.

If the uplink grant indicated that the UE 104 is to perform channel measurement, then a network entity 102 may transmit a third communication 506. Here, the network entity 102 may transmit one or more CSI-RSs to the UE 104, and the UE 104 may measure the received CSI-RSs at a first process 508. The UE 104 may also generate a CSI report at the first process 508, where the report is based on the CSI-RS measurements. It should be noted that the third communication 506 and the first process 508 may be performed if the network entity 102 triggers channel measurement. These steps may be omitted if the network entity 102 does not trigger channel measurement.

At a second process 510, the UE 104 may determine which one of the two TBs to use for the scheduled uplink transmission. The determination may be based on one or more of: whether the UE 104 is permitted to transmit data in the scheduled uplink transmission, and/or whether the network entity 102 disabled one or more of the TBs for the scheduled uplink transmission.

In a first example, if the network entity 102 disabled one of the two TBs for the uplink transmission and permitted the UE 104 to transmit data (e.g., the UE 104 can transmit both data and control information) , then the UE 104 may determine to use the other TB (e.g., the TB that is not disabled) for the uplink transmission. In this example, the data and control information (e.g., one or more of HARQ ACK and/or A-CSI report) may be multiplexed into the selected TB.

In a second example, the network entity 102 may implicitly disable both of the two TBs for uplink transmission if the network entity 102 does not permit the UE 104 to transmit data. For example, if the UE 104 is not permitted to transmit data via the scheduled uplink, then this may cause both TBs to be disabled. As such, the UE 104 may be required to select a TB for transmission of control information (e.g., UCI including one or more of the CSI report and/or HARQ ACK) . In a first option, the UE 104 may select one or the two TBs based on a preconfigured setting. For example, the UE 104 may select a TB according to a standard rule (e.g., 3GPP standard rule) or according to a network configuration (e.g., provided via the first communication 502) identifying which TB the UE should use.

In a second option, the UE 104 may select a TB of the two TBs based on which of the two TBs has a higher MCS relative to the other TB. For example, the network entity 102 may configure the UE 104 to use the two TBs, but separately assign each TB with different values for corresponding communication parameters. In one example, the network entity 102 may configure a first TB with a first MCS and a first RVID, while a second TB is configured with a second MCS and a second RVID. The UE 104 may then select the first TB or the second TB according to which has relatively higher associated MCS value. However, if the two TBs are configured with the same MCS value, then the UE 104 may select one of the first TB or the second TB based on the standard rule or network configuration. In some examples, if the two TBs are configured with the same MCS value, then the UE 104 may select one of the first TB or the second TB based on an order in which the TBs are configured in the uplink grant. Here, the uplink grant may be configured such that the two TBs are sequentially ordered. The UE 104 may select the initial TB of the sequential order (e.g., the first TB of the sequential ordering in the DCI) for the scheduled uplink transmission.

At a third process 512, the UE 104 may calculate resources for transmitting uplink control information. For example, the UE 104 may calculate a number of coded modulation symbols per layer for the UCI to be multiplexed into the selected TB. That is, the UE 104 may calculate an amount of resources in the selected TB that the UE 104 may use for UCI transmission. The calculation may be based on one or more aspects of the TB selected for the scheduled uplink transmission.

In a first example, if the network entity 102 disabled one of the two TBs for the uplink transmission and permitted the UE 104 to transmit data (e.g., the UE 104 can transmit both data and control information) , then the UE 104 may calculate the amount of resources in the selected TB to use for UCI transmission according to one or more of the following equations. Using equation 1, the UE 104 may calculate the amount of resources of the selected TB that can be used for transmitting a HARQ ACK.

where

- Q′_ACK is the number of coded modulation symbols per layer for HARQ-ACK transmission;

- O_ACK is the number of HARQ-ACK bits;

- if O_ACK≥360, L_ACK=11; otherwise L_ACK is a number of cyclic redundancy check (CRC) bits for HARQ-ACK;

-

- C_UL-SCHis the number of code blocks for the TB selected for uplink transmission and within which the UCI is multiplexed (e.g., the TB actually used by the UE for uplink transmission of the multiplexed data and UCI) ;

- if the DCI format scheduling the uplink transmission (e.g., PUSCH) includes a code block group transmission information (CBGTI) field indicating that the UE 104 shall not transmit the r-th code block, K_r=0; otherwise, K_r is the r-th code block size for the TB selected for uplink transmission and within which the UCI is multiplexed (e.g., the TB actually used by the UE for uplink transmission of the multiplexed data and UCI) ;

-is the number of resources (e.g., symbols) that can be used for transmission of UCI in OFDM symbol l, forin the scheduled uplink transmission andis the total number of OFDM symbols of the scheduled uplink transmission, including all OFDM symbols used for DMRS;

- α is configured by higher layer parameter scaling; and

- l₀ is the symbol index of the first OFDM symbol that does not carry DMRS of the PUSCH, after the first DMRS symbol (s) , in the scheduled uplink transmission.

Using equations 2 and 3, the UE 104 may calculate the amount of resources of the selected TB that can be used for transmitting a HARQ ACK.

where

- Q′_CSI-1 is the number of coded modulation symbols per layer for CSI part 1 transmission;

- O_CSI-1 is the number of bits for CSI part 1;

- if O_CSI-1≥360, L_CSI-1=11; otherwise L_CSI-1 is a number of CRC bits for CSI part 1; and

-

where

- Q′_CSI-2 is the number of coded modulation symbols per layer for CSI part 1 transmission;

- O_CSI-2 is the number of bits for CSI part 2;

- if O_CSI-2≥360, L_CSI-2=11; otherwise L_CSI-2 is a number of CRC bits for CSI part 2; and

-

Thus, if the UE 104 transmits both data and UCI in a selected TB via the scheduled uplink transmission resources, the UE 104 may multiplex the data and UCI by determining the number of resources it requires for the UCI. If the UCI includes both HARQ ACK and a CSI report, then the UE 104 may use all of equations 1-3. If just HARQ ACK, then equation 1. If just CSI report, then just equations 2 and 3.

In a second example, if the network entity 102 does not permit the UE 104 to transmit data via the schedule uplink resources, then such a configuration may cause both of the two TBs for the uplink transmission to be disabled. However, the UE 104 may still need to one of the two TBs for transmission of the UCI. In this example, the UE 104 may calculate the amount of resources in the selected TB to use for UCI transmission according to one or more of the following equations. Using equation 4, the UE 104 may calculate the amount of resources of the selected TB that can be used for transmitting a HARQ ACK.

where

- R is the code rate of the PUSCH (e.g., the resources of the scheduled uplink transmission) of the TB selected for UCI transmission; and

- Q_m is the modulation order of the PUSCH of the TB selected for UCI transmission.

Additionally, the UE 104 may use equations 5 and 6 to calculate the amount of resources of the selected TB that can be used for transmitting a CSI report.

The UE 104 may then multiplex the UCI into the selected TB using the amount of resources it calculated.

At a fourth communication 514, the selected TB may be transmitted. That is, the UCI and data (if permitted by the DCI) may be multiplexed into the selected TB and transmitted to the network entity 102.

FIG. 6 is a flowchart 600 of a method of wireless communication. The method may be performed by a UE (e.g., the UE 104; the apparatus 702) . At 602, the UE may obtain a first message configured to: grant a wireless transmission of control information, and disable a first transmission block (TB) of two TBs used by the wireless node for wireless transmissions. For example, 602 may be performed by an obtaining component 740. Here, a network entity (e.g., network entity 102/180 of FIG. 1) may transmit an uplink grant (e.g., DCI) to the UE, as shown in the second communication 504 of FIG. 5.

At 604, the UE may optionally obtain, prior to the output for transmission of the control information, a CSI reference signal (CSI-RS) , wherein the A-CSI report is based on the obtained CSI-RS. For example, 604 may be performed by the obtaining component 740. For example, the network entity may transmit a CSI-RS for the UE to measure and output a CSI report, as shown in the third communication 506 of FIG. 5.

At 606, the UE may optionally multiplex the control information with the data in the second TB. For example, 606 may be performed by a multiplexing component 742.
