Wherein, the CSI fork includes CQI (Channels quality indication, channel quality indication), PMI (Pre-coding Matrix Indicator, pre-coding matrix indication), RI (Rank Indicator, rank indication).

In the LTE system, the ACK/NACK response message is transmitted on the PUCCH (Physical Uplink Control, Physical Uplink Control Channel) in the format 1/1a/1b (PUCCH format1/1a1/b), if the UE (User Equipment, user equipment) needs to send When uplink data is transmitted on PUSCH (Physical Uplink Shared Channel, physical uplink shared channel), the feedback of CQI/PMI and RI can be periodic feedback or aperiodic feedback. Among them, for periodic feedback of CQI /PMI, RI, if the UE does not need to send uplink data, the periodic feedback CQI/PMI, RI is transmitted on the PUCCH in format 2/2a/2b (PUCCH format2/2a/2b), if the UE needs to send uplink data , the CQI/PMI and RI are transmitted on the PUSCH; for the CQI/PMI and RI fed back aperiodically, they are only transmitted on the PUSCH.

As an advanced long-term evolution system of the LTE evolution standard, LTE-A (Long Term Evolution Advanced) supports a larger transmission rate in the uplink direction, and the transmission of PUSCH supports the form of spatial multiplexing, that is, there are one or two transmissions in one PUSCH Blocks or codeword streams, these transport blocks or codeword streams are mapped to multiple transport layers for transmission.

In the above-mentioned LTE-A system, when PUSCH transmits data information in the way of spatial multiplexing, there are the following problems:

When the PUSCH adopts space division multiplexing to transmit data information and corresponding uplink control signaling needs to be transmitted in the PUSCH, there is no mechanism for transmitting the uplink control signaling on the PUSCH in the prior art.

Detailed ways

In the LTE system, the manner in which uplink control signaling and uplink data multiplex radio frames is shown in FIG. 1 . The channel coding process of uplink control signaling and uplink data multiplexing in the LTE system is shown in Figure 2. The uplink data is transmitted in the form of TB (Transport Block, transport block), and the TB passes through CRC attachment (cyclic redundancy check addition) , Code block segmentation (code block segmentation) and Code blockCRC attachment (sub-block CRC addition), Channel coding (channel coding), Rate matching (rate matching), Code block concatenation (code block synthesis) and coded CQI/PMI Multiplexing of uplink data and control signaling, and finally multiplexing the coded ACK/NACK, RI and uplink data through channel interleaving. The PUSCH transmission mode in the LTE system is shown in Figure 3, and the PUSCH only corresponds to one transmission block or codeword stream.

The encoding process of the above-mentioned uplink control signaling is as follows:

First, the target length is calculated according to a given formula. For ACK/NACK and RI, the target length is calculated by Formula 1.

formula one

For CQI, the target length is calculated by Formula 2.

或β_offset ^RI或β_offset ^CQI)，上行控制信令的个数为O(O是ACK/NACK应答消息或RI信令或CQI/PMI的个数)，Q_m为传输块或码字流的调制方式。Then the target length is Q _ACK =Q _m ·Q', Q _RI =Q _m ·Q', Q _CQI =Q _m ·Q', where M _sc ^PUSCH is the PUSCH bandwidth scheduled by the current subframe, and the number of subcarriers Indicates that N _symb ^PUSCH is the number of SC-FDMA symbols during PUSCH transmission in each subframe (related to the type of SRS and CP), and C, K _r represent the number and size of subblocks after code block division of the transmission block , the value of β _offset ^PUSCH is given by the base station through signaling (

or β _offset ^RI or β _offset ^CQI ), the number of uplink control signaling is O (O is the number of ACK/NACK response messages or RI signaling or CQI/PMI), and Q _m is the number of transport blocks or codeword streams Modulation.

x表示用于加扰时最大化调制符号的欧氏距离的占位符；由于LTE系统中存在ACK/NACK应答消息的个数大于2比特的情况，如在TDD系统中，所以当ACK/NACK应答消息大于2比特时，采用(32，O)的编码方式进行编码。当CQI/PMI的比特数小于等于11比特时，CQI采用(32，O)的编码方式进行编码；否则，先进行CRC添加，然后采用图4所示的长度为7，码率为1/3的咬尾卷积码的编码方式进行编码，最后将ACK/NACK应答消息，RI，CQI/PMI编码后的比特重复，直到满足目标长度为止，编码后的信息比特分别记为[q₀ ^ACK，q₁ ^ACK，q₂ ^ACK，...，

]、[q₀ ^CQI，q₁ ^CQI，q₂ ^CQI，...，]、[q₀ ^RI，q₁ ^RI，q₂ ^RI，...，

]。Then carry out channel coding, ACK/NACK and RI have the same coding method, if the ACK/NACK response message or RI information is 1 bit, in the case that the modulation method is QPSK, the coded information is [O ₀ , y]; When the modulation mode is 16QAM, the encoded information is [O ₀ , y, x, x]; when the modulation mode is 64QAM, the encoded information is [O ₀ , y, x, x, x, x] ; Wherein, O ₀ represents the ACK/NACK response message or RI signaling, and x, y represents the placeholder for maximizing the Euclidean distance of the modulation symbol when scrambling; if the ACK/NACK response message or the RI information is 2 bits , when the modulation method is QPSK, the encoded information is [O ₀ , O ₁ , O ₂ , O ₀ , O ₁ , O ₂ ,]; when the modulation method is 16QAM, the encoded information is [ O ₀ , O ₁ , x, x, O ₂ , O ₀ , x, x, O ₁ , O ₂ , x, x]; when the modulation mode is 64QAM, the encoded information is [O ₀ , O ₁ , x, x, x, x, O ₂ , O ₀ , x, x, x, x, O ₁ , O ₂ , x, x, x, x]; among them, O ₀ , O ₁ represent 2-bit ACK/NACK response message or RI information,

x represents a placeholder for maximizing the Euclidean distance of the modulation symbol during scrambling; since the number of ACK/NACK response messages in the LTE system is greater than 2 bits, such as in the TDD system, when ACK/NACK When the response message is greater than 2 bits, use (32, O) encoding method for encoding. When the number of bits of CQI/PMI is less than or equal to 11 bits, CQI adopts (32, O) encoding method to encode; otherwise, first perform CRC addition, then adopt the length shown in Figure 4 to be 7, and the code rate is 1/3 The tail-biting convolutional code encoding method is used to encode, and finally the ACK/NACK response message, RI, and CQI/PMI encoded bits are repeated until the target length is met. The encoded information bits are respectively recorded as [q ₀ ^ACK , q ₁ ^ACK , q ₂ ^ACK ,...,

], [q ₀ ^CQI , q ₁ ^CQI , q ₂ ^CQI , ..., ], [q ₀ ^RI , q ₁ ^RI , q ₂ ^RI ,...,

].

]。The multiplexing of uplink data and control signaling is to concatenate the coded CQI/PMI information and data in the form of modulation symbols, denoted as [ g ₀ ⁱ , g ₁ ⁱ , g ₂ ⁱ ,...,

].

]，RI信息比特[q₀ ^RI，q₁ ^RI，q₂ ^RI，...，]以及经过数据与控制复用的[g₀ ⁱ，g₀ ⁱ，g₂ ⁱ，...，

]写入到一个虚拟矩阵中去，然后按照先行后列的顺序读出虚拟矩阵，从而保证在后续的调制符号到物理资源映射的过程中，ACK/NACK，RI，CQI/PMI以及数据分别能够映射到如图1所示的位置上。信道交织的具体过程描述如下：The process of channel interleaving is to encode the encoded ACK/NACK information bits [q ₀ ^ACK , q ₁ ^ACK , q ₂ ^ACK , ...,

], RI information bits [q ₀ ^RI , q ₁ ^RI , q ₂ ^RI ,..., ] and [g ₀ ⁱ , g ₀ ⁱ , g ₂ ⁱ , ...,

LTE-A supports a higher uplink transmission rate, so the transmission of PUSCH supports the form of spatial multiplexing. For PUSCH transmitted in the form of spatial multiplexing, the related technology provides the mapping relationship between codeword stream and layer, which is the same as the mapping between codeword stream and layer during LTE system downlink transmission. The specific mapping relationship is shown in Table 3. Show.

table 3

Among them, M _symb ^layer indicates the amount of data transmitted by each layer, M _symb ⁽⁰⁾ and M _symb ⁽¹⁾ respectively indicate the number of symbols on each codeword stream, d ⁽⁰⁾ (i), d ⁽¹⁾ (i ) respectively represent the data on each codeword stream, x ⁽⁰⁾ (i), ..., x ⁽³⁾ (i) represent the data transmitted on each layer respectively.

Therefore, if there are two codeword streams during PUSCH transmission in the LTE-A system, then the corresponding PDCCH control signaling contains the modulation and encoding information of these two transmission blocks or codeword streams, which are respectively denoted as I _MCS ¹ , I _MCS ² .

The PUSCH transmission in the LTE-A system supports space division multiplexing, but there is a lack of a transmission mechanism for uplink control signaling to be transmitted on the PUSCH when the PUSCH uses space division multiplexing to transmit data.

In order to solve the above problems, an embodiment of the present invention provides a method for transmitting uplink control signaling, which solves the problem of no mechanism for transmitting uplink control signaling when the PUSCH is space-division multiplexed.

It can be seen from Table 3 that two transport blocks or codeword streams in PUSCH can be mapped to multiple transport layers; the embodiments of the present invention all take two transport layers in PUSCH as an example for illustration, and the two transport layers of PUSCH Corresponding to the transmission blocks TB1 and TB2 respectively, the corresponding modulation and coding schemes are I _MCS ¹ , I _MCS ² , and the code rates of the two transmission blocks or codeword streams are

i＝1and2，其中，M_sc ^PUSCH是当前子帧调度的PUSCH带宽，以子载波的个数表示，N_symb ^PUSCH是每个子帧PUSCH传输时的SC-FDMA的符号个数(和SRS和CP的类型有关)，C，K_r表示对传输块进行码块分割后的子块个数和大小，β_offset ^UCI(

或β_offset ^RI或β_offset ^CQI)的值是由基站通过信令给出的，代表上行控制信令和数据的性能偏移量，上行控制信令的个数为O_UCI(O_UCI是ACK/NACK或RI或CQI/PMI的个数)，Q_m ¹，Q_m ²为两个传输块或码字流的调制方式。本发明的实施例中，以在PUSCH上传输上行信令ACK/NACK、RI及CQI/PMI为例时行说明，但在PUSCH上传输的上行控制信令并不限于上述三种，本发明的实施例对此不作限定。

i=1and2, wherein, M _sc ^PUSCH is the PUSCH bandwidth of the current subframe scheduling, represented by the number of subcarriers, and N _symb ^PUSCH is the number of SC-FDMA symbols (and SRS and CP type), C, K _r represent the number and size of sub-blocks after the transmission block is divided into code blocks, β _offset ^UCI (

or β _offset ^RI or β _offset ^CQI ) is given by the base station through signaling, representing the performance offset of uplink control signaling and data, and the number of uplink control signaling is O _UCI (O _UCI is ACK/ The number of NACK or RI or CQI/PMI), Q _m ¹ and Q _m ² are the modulation modes of two transmission blocks or codeword streams. In the embodiment of the present invention, the transmission of uplink signaling ACK/NACK, RI, and CQI/PMI on the PUSCH is taken as an example for illustration, but the uplink control signaling transmitted on the PUSCH is not limited to the above three types. The embodiment does not limit this.

Firstly, Embodiment 1 of the present invention will be introduced with reference to the accompanying drawings.
