With the fragmentation of frequency resources, the demand for scheduling data of multiple cells at the same time has gradually increased. In order to reduce the control message overhead, it is proposed to schedule data of multiple cells through a single DCI, such as DCI used to schedule multiple cells (data). , can be called MC-DCI, where MC represents multi-cell or multi-carrier.

DCI is obtained by the terminal through blind detection of the Physical Downlink Control Channel (PDCCH). As a newly introduced DCI, MC-DCI is different from traditional (legacy) DCI. In order to obtain MC-DCI through blind detection of PDCCH DCI and legacy DCI, the complexity of blind inspection will increase. At the same time, if the MC-DCI contains information for scheduling multiple cells, the size of the corresponding MC-DCI increases, which also poses a greater challenge to the transmission performance of the PDCCH.

Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this disclosure.

The terminology used in the embodiments of the present disclosure is for the purpose of describing specific embodiments only and is not intended to limit the embodiments of the present disclosure. As used in the embodiments of the present disclosure and the appended claims, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly dictates otherwise. It will also be understood that the term "and/or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

It should be understood that although the terms first, second, third, etc. may be used to describe various information in the embodiments of the present disclosure, the information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first information may also be called second information, and similarly, the second information may also be called first information. Depending on the context, the word "if" as used herein may be interpreted as "when" or "when" or "in response to determining."

For the purpose of simplicity and ease of understanding, the terms used in this article are "greater than" or "less than", "higher than" or "lower than" when characterizing size relationships. But for those skilled in the art, it can be understood that: the term "greater than" also covers the meaning of "greater than or equal to", and "less than" also covers the meaning of "less than or equal to"; the term "higher than" covers the meaning of "higher than or equal to". "The meaning of "less than" also covers the meaning of "less than or equal to".

MC-DCI is a newly introduced DCI. The format of MC-DCI can be different from the format of legacy DCI. Legacy DCI includes but is not limited to DCI used for scheduling single cells, such as DCI format 0_0, DCI format 1_0, DCI format 0_1, DCI format 1_1, DCI format 0_2, DCI format 1_2. The format of MC-DCI can be a newly configured format. For example, MC-DCI can include DCI format 0_3 and DCI format 1_3.

MC-DCI can be used to schedule multiple cells, while legacy DCI is used to schedule a single cell. Therefore, the functions of the two DCIs are different, and the meanings of the information fields in the two DCIs are also different. For example, one in MC-DCI A type of information field can indicate the scheduling information of multiple cells, while a type of information field in legacy DCI can only indicate the scheduling information of one cell.

On this basis, the size (size, that is, the number of bits occupied) of MC-DCI and legacy DCI can be different. The more DCI sizes carried in the PDCCH, the terminal can obtain each type of data through blind detection of the PDCCH. The complexity of DCI is higher. For example, when there are five sizes of DCI in the PDCCH, the complexity of the terminal's blind DCI detection is relatively high compared to when there are four sizes of DCI in the PDCCH. This solution is mainly aimed at the technical problem of increasing the complexity of blind PDCCH detection caused by the introduction of MC-DCI.

Figure 1 is a schematic flow chart of a method for receiving scheduling information according to an embodiment of the present disclosure. The scheduling information receiving method shown in this embodiment can be executed by a terminal, which includes but is not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with network equipment, which includes but is not limited to network equipment in 4G, 5G, 6G and other communication systems, such as base stations, core networks, etc.

As shown in Figure 1, the scheduling information receiving method may include the following steps:

In step S101, receive legacy downlink control information legacy DCI sent by the network device, wherein the legacy DCI carries scheduling information, the scheduling information is at least used for scheduling first information, and the first information carries Scheduling information for each cell.

It should be noted that, in all embodiments of the present disclosure, the scheduling cell refers to the data transmission of the scheduling cell, including but not limited to the uplink transmission and transmission of the scheduling cell and the downlink data transmission of the scheduling cell.

In one embodiment, the terminal can receive the legacy DCI sent by the network device, and the network device can carry scheduling information in the legacy DCI, wherein the first information can be scheduled through the scheduling information, such as time domain resources indicating the first information and Frequency domain resources, and the first information may carry scheduling information for scheduling multiple cells.

Among them, the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. That is to say, the terminal obtains the legacy DCI in the embodiment of the present disclosure through blind detection in the PDCCH, can determine the scheduling information in the legacy DCI, and determine the scheduling information in the MC-DCI according to the first information scheduled by the legacy DCI. The blind detection of legacy DCI and MC-DCI in PDCCH reduces the types of DCI that need to be obtained, which is beneficial to reducing the complexity of blind detection.

Although the terminal determines the scheduling information carried in the first information for scheduling multiple cells, it first needs to determine the first information scheduled by the scheduling information in the legacy DCI. However, since the scheduling information in the legacy DCI can directly indicate the time domain resources and Frequency domain resources allow the terminal to directly determine the first information without blind detection, so the operational complexity of blind detection is relatively low. Therefore, embodiments of the present disclosure determine the first information based on the scheduling information, and then obtain the scheduling information for scheduling multiple cells from the first information. Compared with blindly detecting MC-DCI from the PDCCH, the complexity is still relatively low. . Moreover, since the PDCCH only needs to carry legacy DCI, and the scheduling information used to schedule multiple cells is determined based on the information scheduled by the legacy DCI, there is no need to carry MC-DCI in the PDCCH, which is beneficial to reducing DCI in the PDCCH. The number of sizes improves transmission performance.

It should be noted that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in one MC-DCI used to schedule multiple cells, and is also equivalent to the scheduling in multiple legacy DCIs used to schedule multiple cells. information. In the embodiment of this disclosure, it is emphasized that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. This is mainly to describe the difference from when MC-DCI is carried in the PDCCH, rather than to refer to scheduling multiple cells. The scheduling information is MC-DCI, that is, the legacy DCI is carried in the PDCCH. According to the first information scheduled by the legacy DCI, the scheduling information for scheduling multiple cells can be determined. Among them, the scheduling information for scheduling multiple cells is The function can be the same as that of MC-DCI, but the form of information can be different.

In one embodiment, the scheduling information carried by the legacy DCI is used to schedule at least one of the following cells:

The cell where the legacy DCI is received;

The cells corresponding to the preset cell identifiers among the cells that can be scheduled by the legacy DCI (which can be determined according to the agreement or according to the instructions of the network equipment);

The cell indicated by the network device.

The cells scheduled by the scheduling information carried in the legacy DCI received by the terminal from the network device can be determined according to the agreement or according to the network instructions.

For example, the protocol stipulates that the cell is the cell where the terminal receives the legacy DCI, then the terminal can determine that the cell scheduled by the legacy DCI is the cell where the terminal receives the legacy DCI. Furthermore, when the terminal receives the legacy DCI, the cell where it is located can receive the first information according to the legacy DCI (for example, according to the time domain resources and frequency domain resources indicated by the legacy DCI), and obtain from the first information for scheduling multiple Scheduling information of the cell.

For example, the protocol stipulates that the cells scheduled by the legacy DCI include the cells corresponding to the preset cell identifiers among the cells that the legacy DCI can schedule. Then the terminal can determine that the cells scheduled by the legacy DCI are the cells that are preset among the cells that the DCI can schedule. Assume that the cell corresponds to the cell identity, for example, the cell corresponds to the smallest cell identity, or the cell corresponds to the largest cell identity. Furthermore, the terminal can receive the first information according to the legacy DCI (for example, according to the time domain resources and frequency domain resources indicated by the legacy DCI) in the cell corresponding to the preset cell identifier, and obtain the information for scheduling multiple cells from the first information. scheduling information.

For example, the network device sends indication information to the terminal to indicate the cell scheduled by the scheduling information carried in the legacy DCI. Then the terminal can determine the cell scheduled by the received scheduling information in the legacy DCI based on the indication information sent by the network. Furthermore, the terminal can receive the first information according to the legacy DCI (for example, according to the time domain resources and frequency domain resources indicated by the legacy DCI) in the cell indicated by the network device, and obtain the information for scheduling multiple cells from the first information. Scheduling information.

In one embodiment, the first information includes a media access control layer control element MAC CE (Media Access Control Control Element).

The terminal can receive the legacy DCI sent by the network device. The legacy DCI carries scheduling information. The MAC CE can be scheduled through the scheduling information, such as indicating the time domain resources and frequency domain resources of the MAC CE, which can be carried in the MAC CE. There is scheduling information for scheduling multiple cells.

On this basis, the network device only needs to carry the legacy DCI in the PDCCH, and then determines the MAC CE based on the scheduling information in the legacy DCI, and obtains the scheduling information for scheduling multiple cells from the MAC CE, so that the PDCCH does not need to carry the MC. -DCI, the terminal only needs to blindly detect the legacy DCI in the PDCCH, and then determine the MAC CE scheduled by the legacy DCI, and then obtain the scheduling information for scheduling multiple cells in the MAC CE, which is equivalent to MC-DCI Scheduling information.

It should be noted that in addition to MAC CE, the first information may also include other information, such as DCI, that is, the scheduling information in legacy DCI can schedule DCI, and the scheduled DCI carries scheduling information for scheduling multiple cells. , among which, the DCI scheduled by the scheduling information in the legacy DCI can be located on the PDCCH, or can be carried in the form of data in the PDSCH.

Figure 2 is a schematic application diagram of a scheduling information receiving method according to an embodiment of the present disclosure.

As shown in Figure 2, three cells, Cell#0, Cell#1 and Cell#2, are taken as an example. The network device can send legacy DCI to the terminal in Cell#0, and the MAC CE scheduled by the legacy DCI carries the scheduling information used to schedule Cell#1 and Cell#2.

After receiving the legacy DCI sent by the network device in Cell#0, the terminal can determine the MAC CE scheduled by the legacy DCI (for example, the scheduled cell is Cell#0), and then receive the MAC CE in Cell#0, and from the received The MAC CE obtains the scheduling information used to schedule Cell#1 and Cell#2, such as the PDSCH used to schedule Cell#1 and Cell#2. According to the scheduling information used to schedule Cell#1 and Cell#2, the terminal can PDSCH is received in Cell#1 and Cell#2.

It should be noted that after the terminal determines that it has successfully received the MAC CE, it takes a period of time t to parse the MAC CE to determine the scheduling information used to schedule Cell#1 and Cell#2. Therefore, the scheduling information in the MAC CE does not take effect. time, at least at the time when the MAC CE is successfully received, plus the t duration. For example, if the terminal determines that it has successfully received the MAC CE in time slot n, then the terminal can confirm the scheduling information of Cell#1 and Cell#2 after t+time slot n.

Figure 3 is a schematic flowchart of another scheduling information receiving method according to an embodiment of the present disclosure. As shown in Figure 3, the scheduling information for scheduling multiple cells includes at least one type of information field, and the same type corresponds to one information field. The method further includes:

In step S301, a first association relationship between the value of the same type of information field in the scheduling information for scheduling multiple cells and the plurality of scheduling information is determined, and the plurality of scheduling information and the plurality of scheduled information are determined. Scheduling the second association relationship between cells;

In step S302, the scheduling information of each scheduled cell is determined according to the first association relationship and the second association relationship.

In one embodiment, DCI may include multiple types of information domains, such as FDRA (Frequency Domain Resource Assignment, frequency domain resource allocation) domain, ZP CSI-RS trigger (Zero Power Channel Information Reference Signal trigger, zero power channel status Information reference signal trigger) field, partial bandwidth indicator (BandWidth Part indicator) field, etc.

For the DCI of the existing mechanism, one type of information domain can schedule a cell. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

This embodiment can be applied in a scenario where legacy DCI schedules first information, where the first information carries scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells schedules multiple cells.

In this embodiment, the network device may send legacy DCI to the terminal. The legacy DCI carries scheduling information. The scheduling information is used to schedule the first information. The first information carries scheduling information used to schedule multiple cells. The scheduling information of a cell can schedule multiple cells (that is, the scheduled cells). Specifically, the value of a specific information field in the scheduling information used to schedule multiple cells (the value of a certain information field, rather than multiple information field) and multiple scheduling information (that is, the value of one information domain is associated with multiple scheduling information), for example, it is called the first association relationship, and multiple scheduling information and multiple scheduled cells are established. The association relationship is called a second association relationship, for example. Multiple scheduling information types corresponding to the value of one type of information field are the same, for example, corresponding to the frequency domain resources FDRA of different cells, for example, corresponding to the BWP index configured in different cells.

This indication method can be called a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI can be associated with multiple scheduling information, and multiple scheduling information is associated with multiple scheduled cells.

The first association relationship and the second association relationship may be determined in a predefined manner or may be determined in a signaling indication manner. Taking the signaling indication method as an example, the network side can define, based on the signaling indication (for example, Radio Resource Control RRC signaling), a specific value indicated by a specific type of information field in the scheduling information for scheduling multiple cells and the relationship between the multiple scheduling information. The first relationship. The signaling may be signaling configured in the cell where the legacy DCI is received. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the legacy DCI is received. The RRC signaling indicates a specific value indicated by a specific type of information field in the scheduling information used to schedule multiple cells and multiple scheduling information. relationship. Among them, the number of bits occupied by a specific type of information field is related to the range of indication values configured in RRC signaling.

Taking the BWP indication field in the scheduling information used to schedule multiple cells as an example, in a DCI used to schedule three cells (cell ID numbers are 0, 1 and 2 respectively), the corresponding DCI is received in cell 0.

For example, the first association relationship is determined by means of signaling indication. The terminal receives corresponding RRC signaling in cell 0 to determine the value of the BWP indication field in the scheduling information for scheduling multiple cells and the value of the multiple cell configuration BWP id. the first relationship between them. For example, for the BWP indication field, the first association relationship can be as shown in Table 1 below:

Table 1

As shown in Table 1, the number of bits occupied by the BWP indication field is log ₂ (4) = 2. In the scenario where the value of the BWP indication field is 01, it can be determined according to the first association relationship that the value 01 of the BWP indication field is associated with 3 Scheduling information, the first scheduling information is BWP id=2, the second scheduling information is BWP id=3, and the third scheduling information is BWP id=1. Furthermore, according to the second association relationship, it can be determined that the first scheduling information is associated with cell 0, the second scheduling information is associated with cell 1, and the third scheduling information is associated with cell 2. Then it can be determined that the BWP id of cell 0= 2. The BWP id of cell 1=3, and the BWP id of cell 2=1.

共n个调度信息，n等于被调度小区数，其中，调度信息

为小区k ₁的调度信息，

为小区k _j的调度信息，以此类推，

为小区k _n的调度信息，其中k _j为小区id号。 For the information field of the characteristic type in the scheduling information used to schedule multiple cells, the value of the information field can be associated with the scheduling information.

A total of n scheduling information, n equals the number of scheduled cells, where, the scheduling information

is the scheduling information of cell k ₁ ,

is the scheduling information of cell k _j , and so on,

is the scheduling information of cell k _n , where k _j is the cell id number.

The terminal may determine a first association relationship between the value of a specific information field in the scheduling information for scheduling multiple cells and the multiple scheduling information, and a second association relationship between the multiple scheduling information and the multiple scheduled cells, Then, multiple scheduling information corresponding to the value of the specific information field in the scheduling information for scheduling multiple cells can be determined according to the first association relationship, and the scheduled cell corresponding to each scheduling information can be determined according to the second association relationship, and then the determined Scheduling information for each scheduled cell. Therefore, on the basis that the network device schedules multiple cells through the scheduling information used to schedule multiple cells, the terminal can accurately interpret the scheduling information of each cell indicated by the scheduling information used to schedule multiple cells. The above mainly introduces the specific implementation method of the first association relationship, and the determined relationship corresponding to the second association relationship will be expanded below.

It should be noted that, regarding multiple cells scheduled by the scheduling information used to schedule multiple cells, that is, multiple scheduled cells, the terminal can be based on the CIF (Cell Indicator Field) in the scheduling information used to schedule multiple cells. Cell indication domain), it may be pre-agreed with the network device, or it may be determined based on predefined rules (such as protocol agreement), which is not limited by this disclosure.

In one embodiment, determining the first association relationship between the value of a specific information field in the scheduling information for scheduling multiple cells and the plurality of scheduling information includes: determining the first association relationship according to instructions from a network device. An associated relationship. For example, the network device can determine the correlation between the value of the information field (a certain information field, not multiple information fields) in DCI and multiple scheduling information, and then indicate it through RRC (Radio Resource Control, Radio Resource Control) signaling. to the terminal. Of course, it can also be determined based on predefined rules, for example, based on agreement.

In one embodiment, determining the second association relationship between the plurality of scheduling information and the plurality of scheduled cells includes: determining the second association relationship according to a predefined rule.

The first association relationship between the value of the specific information field in the scheduling information for scheduling multiple cells and the multiple scheduling information, and the second association relationship between the multiple scheduling information and the multiple scheduled cells may be stipulated by predefined rules, such as agreed upon by a protocol; it may also be indicated by a network device, where the network device indicates the association relationship by including but not limited to indicating through RRC signaling, indicating through DCI, and indicating through MAC CE. Give instructions. The number of bits occupied by the information domain in the scheduling information for scheduling multiple cells is determined by the number of values determined based on signaling instructions or predetermined methods. For example, if the first association defines N The value of the information field, the value of each information field is associated with multiple scheduling information, then the number of bits occupied by the information field in the scheduling information used to schedule multiple cells is equal to log ₂ (N).

The following embodiments mainly illustrate the case where the second association relationship is stipulated by predefined rules.

In one embodiment, the scheduling information for scheduling multiple cells includes n scheduling information, and the multiple scheduled cells include n scheduled cells; the predefined rule stipulates that the jth of the n scheduling information A piece of scheduling information is associated with the j-th scheduled cell among the n scheduled cells, where 1≤j≤n.

The scheduled cell may include the cell where the terminal receives the legacy DCI and other cells (cells other than the cell where the terminal receives the legacy DCI in the scheduled cell), or may not include the cell where the terminal receives the legacy DCI. Only other neighborhoods are included. When the predefined rules in this implementation stipulate the association between the scheduled cell and the scheduling information, the cell where the terminal receives the legacy DCI and other cells may not be distinguished. The same rule stipulates the cell where the terminal receives the legacy DCI. and the correlation between other cells and scheduling information.

Taking n scheduled cells as an example, n pieces of scheduling information can be determined based on the first association relationship and the value of the information field in the scheduling information for scheduling multiple cells, and n pieces of scheduling information and n scheduled cells can be determined based on the second association relationship. As for the correspondence relationship between cells, the second association relationship may be that the j-th scheduling information among the n scheduling information is associated with the j-th scheduled cell among the n scheduled cells.

Accordingly, the terminal can determine that the jth scheduling information is the scheduling information of the jth scheduled cell, so that on the basis that the network device schedules multiple cells by scheduling the scheduling information of multiple cells, the terminal can accurately interpret the schedule. Scheduling information for each cell indicated by the scheduling information of multiple cells.

In this embodiment, the terminal can determine based on the second association relationship that the first scheduling information is the BWP information of the first scheduled cell (cell k ₁ ), and the second scheduling information is the second scheduled cell (cell k ₂ ) The BWP information,..., the jth scheduling information is the BWP information of the jth scheduled cell (cell k _j ),..., the nth BWP scheduling information is the nth scheduled cell (cell k _n ) BWP information, so that on the basis of scheduling multiple cells by scheduling the scheduling information of multiple cells, the terminal can accurately interpret the BWP information of each cell indicated by the scheduling information of scheduling multiple cells.

How to determine the order of multiple scheduled cells will be described in subsequent embodiments.

The following exemplifies how to determine the order of multiple scheduled cells by using several embodiments to illustrate how the predefined rules stipulate the association between the cell where the terminal is located when receiving the legacy DCI and other cells and the information domain according to the same rules.

In one embodiment, the predefined rule stipulates that the identity of the jth scheduled cell is less than the identity of the j+1th scheduled cell, for example, k _j is less than k _j+1 ; or, the predefined rule stipulates that the identity of the jth scheduled cell is less than the identity of the j+1th scheduled cell. The identity of the j scheduled cell is greater than the identity of the j+1th scheduled cell, for example, k _j is greater than k _j+1 .

In one implementation, the terminal can determine the identity of the scheduled cell (for example, Cell ID) based on the RRC signaling sent by the network device, for example, based on the information elements (Information Element, IE) such as ServcellIndex and/or SCellIndex in the RRC signaling. Determine; if the identity of the cell corresponds to PCI (Physical Cell Identity, physical cell identity), it can be determined based on the information element PhysCellId in the RRC signaling; of course, it can also be determined based on other signaling. Or, determined in other ways, such as may be specified by predefined rules.

The predefined rules can stipulate that the scheduled cells are sorted according to the identities of the scheduled cells. For example, the identities can be sorted from small to large, then the identity of the jth scheduled cell is smaller than the identity of the j+1th scheduled cell. Or the identifiers are sorted from large to small, then the identifier of the j-th scheduled cell is greater than the identifier of the j+1-th scheduled cell.

For example, four scheduled cells are taken as an example, namely cell #1 with an identifier of 1, cell #2 with an identifier of 2, cell #3 with an identifier of 3, and cell #4 with an identifier of 4. If sorted according to the identifier from small to large, then k _j is smaller than k _j+1 , it can be determined that the first cell is cell #1, the second scheduled cell is cell #2, the third cell is cell #3, and the second scheduled cell is cell #3. The 4 cells are cell #4; if they are sorted from large to small, then k _j is greater than k _j+1 , it can be determined that the first cell is cell #4, the second scheduled cell is cell #3, and the 3rd cell is cell #4. The first cell is cell #2, and the fourth cell is cell #1.

Accordingly, the ordering of the cells can be accurately determined according to the identities of the cells, and further the j-th information field can be determined to be the scheduling information of the j-th scheduled cell.

FIG. 4 is a schematic flow chart of yet another scheduling information receiving method according to an embodiment of the present disclosure. As shown in Figure 4, the scheduling information for scheduling multiple cells includes at least one type of information field, and the same type corresponds to multiple information fields. The method further includes:

In step S401, determine the association between multiple information domains of the same type in the scheduling information for scheduling multiple cells and multiple scheduled cells;

In step S402, the scheduling information of each scheduled cell is determined based on the value of each information field and the association relationship.

For the DCI of the existing mechanism, the same type of information domain generally contains only one. A cell can be scheduled according to this type of information domain. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

This embodiment can be applied in a scenario where legacy DCI schedules first information, where the first information carries scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells schedules multiple cells.

In this embodiment, the network device may send legacy DCI to the terminal. The legacy DCI carries scheduling information. The scheduling information is used to schedule the first information. The first information carries scheduling information used to schedule multiple cells. The scheduling information of one cell can schedule multiple cells (that is, the scheduled cells). One possible design method is as follows: for one or more types of information fields in the scheduling information used to schedule multiple cells, for For multiple scheduled cells, multiple information fields of the same type can be set in the scheduling information used to schedule multiple cells, and each information field can be scheduled for one of the cells. Information fields of the same type correspond to indicating the same type of information, for example, indicating frequency domain resources FDRA of different cells, for example, indicating BWP indexes configured in different cells.

This indication method may be called a separate method. For example, a specific type of information field in the scheduling information used to schedule multiple cells may include multiple information fields. On the basis of scheduling the information field of a single cell, the specific type of information field can be extended with corresponding bits according to the number of scheduled cells, thereby obtaining multiple information fields of the same type, in which different information fields indicate messages from different cells. . The number of bits occupied by multiple information fields of the same type is equal to the sum of the number of bits occupied by the above information fields corresponding to each scheduled cell (of course it can be set to be equal to other numbers as needed). The number of bits occupied by the above-mentioned information field corresponding to each scheduled cell can be the same as the number of bits occupied by the same type of information field used to schedule the DCI of a cell in the existing mechanism, or it can also be the same as the number of bits occupied by the DCI of a cell scheduled in the existing mechanism. The maximum number of bits occupied by information fields of the same type is the same.

Figure 5 is a schematic flowchart of a scheduling information sending method according to an embodiment of the present disclosure. The scheduling information sending method shown in this embodiment can be executed by a network device that can communicate with a terminal. The network device includes but is not limited to base stations in communication systems such as 4G base stations, 5G base stations, and 6G base stations. Terminals include but are not limited to mobile phones, tablets, wearable devices, sensors, Internet of Things devices and other communication devices.

As shown in Figure 5, the scheduling information sending method may include the following steps:

In step S501, legacy downlink control information legacy DCI is sent to the network device, where the legacy DCI carries scheduling information, the scheduling information is at least used for scheduling first information, and the first information carries the scheduling information for scheduling multiple Scheduling information of the cell.

In one embodiment, the network device can send legacy DCI to the terminal, and the legacy DCI can carry scheduling information, wherein the first information can be scheduled through the scheduling information, such as time domain resources and frequency domain resources indicating the first information. , and the first information may carry scheduling information for scheduling multiple cells.

Among them, the scheduling information used to schedule a single cell is equivalent to the scheduling information in legacy DCI, and the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. That is to say, the terminal obtains the legacy DCI in the embodiment of the present disclosure through blind detection in the PDCCH, can determine the scheduling information in the legacy DCI, and determine the scheduling information in the MC-DCI according to the first information scheduled by the legacy DCI. The blind detection of legacy DCI and MC-DCI in PDCCH reduces the types of DCI that need to be obtained, which is beneficial to reducing the complexity of blind detection.

Although the terminal determines the scheduling information carried in the first information for scheduling multiple cells, it first needs to determine the first information scheduled by the scheduling information in the legacy DCI. However, since the scheduling information in the legacy DCI can directly indicate the time domain resources and Frequency domain resources allow the terminal to directly determine the first information without blind detection, so the operational complexity of blind detection is relatively low. Therefore, embodiments of the present disclosure determine the first information based on the scheduling information, and then obtain the scheduling information for scheduling multiple cells from the first information. Compared with blindly detecting MC-DCI from the PDCCH, the complexity is still relatively low. . Moreover, since the PDCCH only needs to carry legacy DCI, and the scheduling information used to schedule multiple cells is determined based on the information scheduled by the legacy DCI, there is no need to carry MC-DCI in the PDCCH, which is beneficial to reducing DCI in the PDCCH. The number of sizes improves transmission performance.

It should be noted that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI, and is also equivalent to the scheduling information in multiple legacy DCI used to schedule multiple cells. In the embodiment of this disclosure, it is emphasized that the scheduling information used to schedule multiple cells is equivalent to the scheduling information in MC-DCI. This is mainly to describe the difference from when MC-DCI is carried in the PDCCH, rather than to refer to scheduling multiple cells. The scheduling information is MC-DCI, that is, the legacy DCI is carried in the PDCCH. According to the first information scheduled by the legacy DCI, the scheduling information for scheduling multiple cells can be determined. Among them, the scheduling information for scheduling multiple cells is The function can be the same as that of MC-DCI, but the form of information can be different.

In one embodiment, the scheduling information carried by the legacy DCI is used to schedule at least one of the following cells:

The cell used to send the legacy DCI;

The cell corresponding to the preset cell identifier among the cells that can be scheduled by the legacy DCI;

The cell indicated by the network device.

The cells scheduled by the scheduling information carried in the legacy DCI sent by the network equipment to the terminal can be determined according to the agreement, or determined independently by network instructions, and then informed to the terminal through the instruction information.

For example, the protocol stipulates that the cell is the cell used by the network device to send the legacy DCI, then the network device can determine that the cell scheduled by the legacy DCI sent to the terminal is the cell used to send the legacy DCI. Furthermore, the network device may send the first information to the terminal in the cell used to send the legacy DCI, and use the first information to carry scheduling information for scheduling multiple cells.

For example, the protocol stipulates that the cells scheduled by the legacy DCI include the cells corresponding to the preset cell identifiers among the cells that the legacy DCI can schedule. Then the network can determine that the cells scheduled by the legacy DCI sent to the terminal are the cells that the legacy DCI can schedule. Among the scheduled cells, a cell corresponding to a preset cell ID is preset, for example, a cell corresponding to the smallest cell ID, or a cell corresponding to the largest cell ID. Furthermore, the network device may send the first information to the terminal in the cell corresponding to the preset cell identifier, and use the first information to carry scheduling information for scheduling multiple cells.

For example, the network device can independently determine the cells scheduled by the legacy DCI sent to the terminal as needed, and then send indication information to the terminal to indicate the cells scheduled by the scheduling information carried in the legacy DCI. Furthermore, the network device may send first information to the terminal in the indicated cell, and the first information carries scheduling information for scheduling multiple cells.

In one embodiment, the first information includes a media access control layer control element MAC CE.

The network device can send legacy DCI to the terminal, and the legacy DCI carries scheduling information for scheduling a single cell, wherein the MAC CE can be scheduled through the scheduling information, such as indicating the time domain resources and frequency domain resources of the MAC CE, and in The MAC CE can carry scheduling information for scheduling multiple cells.

On this basis, the network device only needs to carry the legacy DCI in the PDCCH, and then determines the MAC CE based on the scheduling information in the legacy DCI, and obtains the scheduling information for scheduling multiple cells from the MAC CE, so that the PDCCH does not need to carry the MC. -DCI, the terminal only needs to blindly detect the legacy DCI in the PDCCH, and then determine the MAC CE scheduled by the legacy DCI, and then obtain the scheduling information for scheduling multiple cells in the MAC CE, which is equivalent to MC-DCI scheduling information.

It should be noted that in addition to MAC CE, the first information may also include other information, such as DCI, that is, the scheduling information in legacy DCI can schedule DCI, and the scheduled DCI can be carried in the PDSCH without having to be carried in the PDCCH. middle.

In one embodiment, DCI may include multiple types of information fields, such as FDRA fields, ZP CSI-RS trigger fields, partial bandwidth indication fields, etc.

For the DCI of the existing mechanism, one type of information domain can schedule a cell. For example, the FDRA information domain can schedule the frequency domain resources of the target cell.

This embodiment can be applied in a scenario where legacy DCI schedules first information, where the first information carries scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells schedules multiple cells.

In this embodiment, the network device may send legacy DCI to the terminal. The legacy DCI carries scheduling information. The scheduling information is used to schedule the first information. The first information carries scheduling information used to schedule multiple cells. The scheduling information of a cell can schedule multiple cells (that is, the scheduled cells). Specifically, the value of a specific information field in the scheduling information used to schedule multiple cells (the value of a certain information field, rather than multiple information field) and multiple scheduling information (that is, the value of one information domain is associated with multiple scheduling information), for example, it is called the first association relationship, and multiple scheduling information and multiple scheduled cells are established. The association relationship is called a second association relationship, for example. Multiple scheduling information types corresponding to the value of one type of information field are the same, for example, corresponding to the frequency domain resources FDRA of different cells, for example, corresponding to the BWP index configured in different cells.

This indication method can be called a combined or shared indication. For example, a specific value indicated by a specific type of information field in a DCI can be associated with multiple scheduling information, and multiple scheduling information is associated with multiple scheduled cells.

The first association relationship and the second association relationship may be determined in a predefined manner or may be determined in a signaling indication manner. Taking the signaling indication method as an example, the network side can define, based on the signaling indication (for example, Radio Resource Control RRC signaling), a specific value indicated by a specific type of information field in the scheduling information for scheduling multiple cells and the relationship between the multiple scheduling information. The first relationship. The signaling may be signaling configured in the cell where the legacy DCI is received. Taking RRC signaling as an example, the terminal receives the corresponding RRC signaling in the cell where the legacy DCI is received. The RRC signaling indicates a specific value indicated by a specific type of information field in the scheduling information used to schedule multiple cells and multiple scheduling information. relationship. Among them, the number of bits occupied by a specific type of information field is related to the range of indication values configured in RRC signaling.

In the existing DCI, the same type of information domain generally contains only one. A cell can be scheduled according to this type of information domain. For example, the FDRA information domain can schedule the frequency domain resources of the cell.

This embodiment can be applied in a scenario where legacy DCI schedules first information, where the first information carries scheduling information for scheduling multiple cells, and the scheduling information for scheduling multiple cells schedules multiple cells.

In this embodiment, the network device can determine the association between multiple information domains of the same type and multiple scheduled cells, and then set the information domain of each cell according to the association relationship, thereby generating a message for scheduling multiple cells. The scheduling information of the cells is sent to the terminal to realize the scheduling of multiple cells. Information fields of the same type correspond to indicating the same type of information, for example, indicating frequency domain resources FDRA of different cells, for example, indicating BWP indexes configured in different cells.

This indication method may be called separate indication. For example, a specific type of information field in the scheduling information used to schedule multiple cells may include multiple information fields. On the basis of scheduling the information field of a single cell, the specific type of information field can be extended with corresponding bits according to the number of scheduled cells, thereby obtaining multiple information fields of the same type, in which different information fields indicate messages from different cells. . The number of bits occupied by multiple information fields of the same type is equal to the sum of the number of bits occupied by the above information fields corresponding to each scheduled cell (of course it can be set to be equal to other numbers as needed). The number of bits occupied by the above information field corresponding to each scheduled cell is the same as the number of bits occupied by the same type of information field occupied by the DCI of a cell scheduled in the existing mechanism.
