[0035] In related technologies, a single DCI with a format of 0-3 / 1-3 can be used to schedule data channels for multiple cells, including the Physical Uplink Shared Channel (PUSCH) or the Physical Downlink Shared Channel (PDSCH). There are two ways the DCI indicates the cells to be scheduled. The first way is through the scheduled cell indictor field in the DCI, indicating a combination of cells to be scheduled. This involves a table configured on the network side device showing combinations of cells that can be scheduled, with each row representing a group of cells to be scheduled, and the scheduled cell indictor field indicating one of those rows. The second way is through the Frequency Domain Resource Allocation (FDRA) field. An invalid FDRA field indicates that the corresponding cell has not been scheduled, while a valid FDRA field indicates that the corresponding cell has been scheduled. For DCI fields of type 2 (formats 0-3 / 1-3), such as FDRA, New Data Indicator (NDI), and Redundancy Version (RV), each cell has a corresponding block. The number of blocks varies depending on the indication method of the scheduled cell. For the first method, the number of blocks... For the second method, the number of cells being scheduled is [number of cells], and the number of blocks is [number of blocks]. The number of cells that can be scheduled, as configured.

[0036] In related technologies, the Time Domain Resource Allocation (TDRA) table is a joint configuration table for multiple cells, containing all the bandwidth parts (BWPs) of the scheduled cells. Each entry in the table corresponds to all the start and length indicator values ​​(SLIVs) of a row in the TDRA table for a BWP of a cell.

[0037] The DCI can also include a secondary cell (SCell) dormancy indication. The DCI can reinterpret the modulation and coding scheme (MCS) field, NDI field, RV field, Hybrid automatic repeat request process number (HPN) field, and antenna port(s) field by invalidating the FDRA (all "0" or all "1"). When the bitmap corresponding to the SCell is '0', it means that the BWP of the SCell has switched to the dormancy state.

[0038] After receiving a DCI, the terminal can also feed back a HARQ codebook for that DCI. Type 2 codebook feedback is performed for each DCI, with a fixed maximum number of bits fed back for each DCI. The number of valid bits fed back depends on the number of data channels actually scheduled for the DCI and the HARQ binding configuration. If the number of valid bits fed back is less than the maximum number of bits, then negative acknowledgments (NACKs) are padded after the valid bit count until the maximum number of bits is reached.

[0039] Therefore, it can be seen that in related technologies, a DCI can only schedule one data channel in a cell, resulting in low DCI utilization.

[0040] In addition, if DCI is to be used to schedule multiple cells, and one cell can schedule multiple PUSCH / PDSCH, then how to design RV and NDI in DCI is also a technical problem that needs to be solved, as is how to generate type 2 codebook feedback.

[0041] To address the aforementioned issues, this application provides a signaling acquisition scheme and a signaling transmission scheme to at least solve one of the aforementioned technical problems.

[0042] The technical solutions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0043] Figure 2 shows a schematic flowchart of a signaling acquisition method according to an embodiment of this application. This method 200 can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in Figure 2, the method may include the following steps.

[0044] S210, the terminal receives a DCI, wherein the DCI is used to schedule at least two cells, and at least one of the at least two cells includes multiple data channels.

[0045] In this embodiment of the application, the data channel may include PUSCH or PDSCH.

[0046] In this embodiment, the network-side device sends a Data Channel Interchange (DCI) to the terminal. The DCI is used to schedule at least two cells, and the DCI schedules multiple data channels of at least one of the cells. For example, the DCI schedules three cells: cell 1, cell 2, and cell 3. The DCI schedules PDSCH 1 of cell 1, PDSCH 1 and PDSCH 2 of cell 2, and PDSCH 1 of cell 3.

[0047] S212, the terminal obtains scheduling information of at least one data channel of each of the at least two cells based on the DCI.

[0048] In this embodiment of the application, the terminal can parse the DCI to obtain the scheduling information of at least one data channel of each cell scheduled by the DCI.

[0049] Through the technical solution provided in the embodiments of this application, the terminal can obtain the scheduling information of at least one data channel of each of the at least two cells from the received DCI, thereby scheduling multiple cells through one DCI, and scheduling at least one of the multiple data channels of one cell, saving DCI overhead and improving the utilization rate of DCI.

[0050] In some embodiments, in S212 above, the terminal obtaining scheduling information of at least one data channel of each of the at least two cells based on the received DCI may include the following steps:

[0051] Step 1: The terminal determines the number of bits in the second DCI field of the DCI based on at least one first DCI field of the DCI, wherein the first DCI field includes at least one of the following: a scheduling cell indication field for indicating the at least two cells to be scheduled, an FDRA field for indicating the frequency domain information of the data channel to be scheduled, and a TDRA field for indicating the time domain information of the data channel to be scheduled; and the second DCI field includes at least one of the following: an RV field and an NDI field.

[0052] Step 2: The terminal determines the second DCI field of the DCI based on the number of bits in the second DCI field;

[0053] Step 3: The terminal obtains scheduling information of at least one data channel of each of the at least two cells based on the information carried in the at least one first DCI field and the second DCI field of the DCI.

[0054] Through the above embodiments, the DCI may include at least one first DCI field. The first DCI field indicates at least one of the scheduling cell indication, the frequency domain information FDRA of the scheduled data channel, and the frequency domain information TDRA of the scheduled data channel of the at least two cells being scheduled. Based on the at least one first DCI field, the terminal can determine the number of bits in the second DCI field, that is, the number of bits occupied by the RV field or the NDI field. Thus, based on the number of bits in the second DCI field, the terminal can obtain the scheduling information of at least one data channel of each of the at least two cells from the received DCI, thereby enabling the terminal to accurately obtain the scheduling information sent by the network-side device.

[0055] In some embodiments, the terminal determining the number of bits in the second DCI field based on at least one first DCI field may include: when the first DCI field includes the scheduling cell indication field and the TDRA field, the terminal determines that the second DCI field includes N1 first bit blocks, each first bit block containing Mi bits, wherein N1 is the number of the at least two scheduled cells determined based on the scheduling cell indication field, and Mi is the number of scheduled data channels in each scheduled cell determined according to the scheduling cell indication field and the TDRA field. In these embodiments, when the first DCI field includes the scheduling cell indication field and the TDRA field, the terminal may determine the number of scheduled cells N1 based on the scheduling cell indication field, determine the number of scheduled data channels Mi in each scheduled cell based on the scheduling cell indication field and the TDRA field, and then determine that the second DCI field includes N1 first bit blocks, each first bit block containing Mi bits.

[0056] In the above embodiments, the second DCI field can be a type 2 DCI field (meaning each block indicates information corresponding to one cell). The terminal can determine the combination of cells to be scheduled based on the scheduling cell indication field, and since this combination includes N1 cells, the number of blocks corresponding to the second DCI field can be determined to be N1.

[0057] For example, NDI is: block number 1, block number 2, ..., block number in, It is N1.

[0058] Each block contains Mi bits. The SLIV of the PDSCH / PUSCH of the cells to be scheduled is indicated by the TDRA field, and the number of PDSCH / PUSCH for each cell is also determined as Mi. For example, when the scheduling cell indication field indicates that the combination of cells to be scheduled is {cell1, cell2}, then N1 = 2, block number 1 is the NDI of cell1, and block number 2 is the NDI of cell2. The combination of cell1 and cell2 determined by the TDRA indication is {2PDSCH, 4PDSCH}, the number of block number 1 is 2, and the number of block number 2 is 4.

[0059] In other embodiments, the terminal determining the number of bits in the second DCI field based on at least one first DCI field may include: when the first DCI field includes the scheduling cell indication field, the terminal determines that the second DCI field includes N1 second bit blocks, each second bit block containing M2 bits, wherein N1 is the number of the at least two scheduled cells determined based on the scheduling cell indication field, and M2 is the maximum number of data channels that can be scheduled for a first cell combination determined according to the scheduling cell indication field and the configured TDRA table, the first cell combination being the cell combination corresponding to the at least two scheduled cells.

[0060] In the above embodiment, the first cell combination of cells to be scheduled can be determined according to the scheduling cell indication field. Based on the number of cells included in the first cell combination, the terminal can determine the number N1 of the at least two cells to be scheduled, and then determine that the second DCI field includes N1 bit blocks. Then, based on the pre-configured TDRA table, the maximum number M2 of data channels that the first cell combination can be scheduled can be determined, and the number of bits contained in each bit block is determined to be M2. Through this embodiment, the information carried in the first DCI field can be reduced.

[0061] In some other embodiments, the terminal determining the number of bits in the second DCI field in at least one first DCI field based on DCI may include: when the first DCI field includes the FDRA field and the FDRA field is used to indicate whether a cell is scheduled, the terminal determines that the second DCI field includes N2 third bit blocks, each third bit block containing the number of bits Mi', where N2 is the maximum number of schedulable cells determined according to the configuration of the network-side equipment (or the maximum number of cells included in the cell set), and Mi' is the maximum number of data channels that each schedulable cell can be scheduled according to the configured TDRA table.

[0062] In the above embodiment, the first DCI field includes an FDRA field. When FDRA is used to indicate whether a cell is scheduled, for example, all "0"s or all "1"s indicate that the cell is not scheduled, and other values ​​indicate that it is scheduled, then the second DCI field can be determined to contain N2 bit blocks, and each bit block contains Mi' bits. N2 is the maximum number of schedulable cells determined according to the network-side device configuration, and Mi' is the maximum number of PDSCH / PUSCHs that can be scheduled for each schedulable cell as determined by the configured TDRA table.

[0063] For example, NDI is: block number 1, block number 2, ..., block number in, It is N2.

[0064] Each block contains Mi' bits, where Mi' is the maximum number of PDSCH / PUSCHs that can be scheduled for each schedulable cell, as determined by the configured TDRA table. For example, if the FDRA indicates the schedulable cells and the network-side equipment is configured to allow a maximum of 4 schedulable cells, then N2 = 4, block number 1 is the NDI of cell 1, and block number 2 is the NDI of cell 2. According to the TDRA table corresponding to the DCI, the maximum number of schedulable PDSCHs for cell 1 is 4, and the maximum number of schedulable PDSCHs for cell 2 is 8. The number of blocks in block number 1 is 4, and the number of blocks in block number 2 is 8. It should be noted that the 4 PDSCHs of cell 1 + the 8 PDSCHs of cell 2 may not actually be schedulable, but can accommodate the number of bits for all possible schedulable combinations.

[0065] Through the above embodiments, different methods of determining the DCI field are adopted for different methods of indicating the scheduled cell. When the scheduling small area is used to indicate the scheduled cell, bit overhead can be saved and the flexibility of the DCI field can be improved. When the FDRA is used to indicate the scheduled cell, the position of the field and the number of bits can be fixed, reducing the complexity of the terminal receiving the DCI.

[0066] Figure 3 illustrates another flowchart of the signaling acquisition method in an embodiment of this application, which can be executed by a terminal. In other words, the method can be executed by software or hardware installed on the terminal. As shown in Figure 3, the method may include the following steps.

[0067] S310, the terminal receives a DCI, wherein the DCI is used to schedule at least two cells, and at least one of the at least two cells includes multiple data channels.

[0068] This step is the same as S210 above, and you can refer to the relevant description above for details, which will not be repeated here.

[0069] S312, the terminal obtains scheduling information of at least one data channel of each of the at least two cells based on the DCI.

[0070] This step is the same as S212 above, and you can refer to the relevant description above for details, which will not be repeated here.

[0071] S314, the terminal determines the number of bits fed back from the HARQ codebook.

[0072] After receiving the DCI, the terminal obtains the number of bits fed back from the HARQ codebook corresponding to the DCI, and then feeds back the feedback information corresponding to the DCI to the network-side device.

[0073] It should be noted that there is no strict execution order between S312 and S314. S314 can be executed after S312 or before S312. The specific implementation of this application does not limit this.

[0074] S316, the terminal generates a HARQ codebook based on the determined number of bits fed back from the HARQ codebook.

[0075] After determining the number of bits to be fed back in the HARQ codebook, the terminal can generate the corresponding HARQ codebook based on that number of bits.

[0076] S318, feedback of the HARQ codebook.

[0077] Through the above embodiments, after receiving the DCI for scheduling multiple data channels of multiple cells, and at least one of the cells, the terminal feeds back the HARQ codebook to the network-side device. The HARQ codebook fed back indicates the reception status of the DCI, so that the network-side device can know whether the terminal has successfully received the DCI, avoiding inconsistencies between the understanding between the terminal and the network-side device.

[0078] In some embodiments, the terminal determining the number of bits fed back in the HARQ codebook may include: the terminal determining the number of bits fed back in the HARQ codebook as a first value.

[0079] In some implementations, the first value may be the maximum number of HARQ bits corresponding to each cell combination that can be scheduled, wherein the number of HARQ bits corresponding to each cell combination that can be scheduled is the sum of the number of HARQ bits corresponding to each cell in each cell combination determined based on the configured TDRA table.

[0080] In the above implementation, based on the configured TDRA table (or the TDRA table corresponding to the DCI), the number of HARQ bits corresponding to each schedulable cell combination is determined as follows: Where M is the number of cells in the cell combination, and Ni is the number of bits corresponding to the (i+1)th cell in the cell combination, thus determining the maximum number of HARQ bits corresponding to the schedulable cell combination. The maximum number of HARQ bits among all schedulable cell combinations is used to determine the number of bits fed back in the HARQ codebook. In this implementation, the number of bits fed back in the HARQ codebook is independent of the DCI field, making it relatively static; even if a DCI is missed, it will not affect the determination of the number of bits. This further reduces bit overhead.

[0081] For example, if the network-side equipment is configured with the combinations of cells that can be scheduled as {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combinations reported in the current PUCCH is 2. When HARQ spatial bundling and time bundling are not configured, and the codeword for each cell is 1, according to the cell combinations in the TDRA table, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of bits corresponding to the combinations of cells that can be scheduled as {cell1, cell2} and {cell1, cell3} is max(6, 7, 10) = 10.

[0082] For example, if the network-side equipment is configured with the combination of cells that can be scheduled as {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination reported in the current PUCCH is 2. When no spatial bundling and time bundling of HARQ are configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword, according to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Therefore, the maximum number of bits corresponding to the combination of cells that can be scheduled as {cell1, cell2} and {cell1, cell3} is max(8, 8, 10) = 10.

[0083] For example, if the network-side equipment is configured to schedule cell combinations of {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combinations reported in the current PUCCH is 2. When HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword each, and cell1 is configured with time bundling, the number of groups is 2. According to the cell combinations in the TDRA table, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Therefore, the maximum number of bits corresponding to the scheduled cell combinations {cell1, cell2} and {cell1, cell3} is max(6, 4, 6) = 6.

[0084] In another implementation, the first value is the maximum value among the maximum number of HARQ bits corresponding to each cell combination that can be scheduled, wherein the maximum number of HARQ bits corresponding to the cell combination is the sum of the maximum number of HARQ bits corresponding to each cell in each cell combination determined based on the configured TDRA table.

[0085] In the above implementation, the number of bits for HARQ codebook feedback is determined according to the TDRA table corresponding to DCI. Xi represents the maximum number of HARQ bits corresponding to the i-th cell in the schedulable cell combination, and M represents the number of cells in one of the at least one schedulable cell combinations. Using this implementation, the number of bits in the HARQ codebook is independent of the DCI field, making it relatively static; even if a DCI is missed, it will not affect the determination of the number of bits. This saves bit overhead.

[0086] For example, if the network-side equipment is configured to schedule cell combinations of {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combinations in the current PUCCH feedback is 2. When no spatial bundling and time bundling of HARQ are configured, and the codeword of each cell is 1, according to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Therefore, the maximum number of feedback bits corresponding to cell1, cell2, and cell3 are 6, 2, and 4 respectively. Thus, the maximum number of bits corresponding to the scheduled cell combinations {cell1, cell2} and {cell1, cell3} is max(8, 10) = 10.

[0087] For example, if the network-side equipment is configured to schedule cell combinations {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combinations in the current PUCCH feedback is 2. When HARQ spatial bundling and time bundling are not configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword, according to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of feedback bits for cell1, cell2, and cell3 are 6, 2*2, and 4 respectively. Thus, the maximum number of bits corresponding to the scheduled cell combinations {cell1, cell2} and {cell1, cell3} is max(10, 10) = 10.

[0088] For example, if the network-side equipment is configured to schedule cell combinations {cell1, cell2} and {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combinations in the current PUCCH feedback is 2. When HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword, and cell1 is configured with time bundling, the number of groups is 2. According to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then the maximum number of feedback bits corresponding to cell1, cell2, and cell3 are 2, 2, and 4, respectively. Therefore, the maximum number of bits corresponding to the scheduled cell combinations {cell1, cell2} and {cell1, cell3} is max(4, 6) = 6.

[0089] In some embodiments, the terminal may determine the number of bits fed back by the HARQ codebook to the first value if a target configuration is configured or the first DCI field of the DCI includes a scheduling cell index field for indicating the at least two cells to be scheduled, wherein the target configuration is used to configure a combination of schedulable cells.

[0090] In some embodiments, the terminal determines the number of bits fed back in the Hybrid Automatic Repeat Request (HARQ) codebook, including: the terminal determines the number of bits fed back in the HARQ codebook as a second value.

[0091] In one implementation, the second value can be the sum of the second numbers corresponding to the first number of cells. The first number is either the maximum number of at least two cells that can be scheduled or the maximum number of cells contained in a configured cell set, and the second number is the maximum number of HARQ bits corresponding to each of the first number of cells determined according to the configured TDRA table.

[0092] In the above implementation, the number of bits for HARQ codebook feedback is determined to be... Xi represents the maximum number of HARQ bits for each schedulable cell determined according to the configured TDRA table, and Y represents the maximum number of schedulable cells or the maximum number of cells in the cell set. In this implementation, the number of bits in the HARQ codebook is independent of the DCI field, making it relatively simple and static. Even if a DCI is missed, it will not affect the determination of the number of bits. The number of bits fed back from the HARQ codebook can be determined even without a schedulable cell combination configuration.

[0093] In the above implementation, based on the configured TDRA table, the maximum number of HARQ bits Xi corresponding to each cell can be determined, and the number of bits corresponding to the cell set (containing all schedulable cells) is... Y represents the number of cells in the cell set, which determines the number of bits that can be fed back from the HARQ codebook.

[0094] For example, if the cell set configured by the network-side equipment includes {cell1, cell2, cell3}, and no spatial bundling or time bundling of HARQ is configured, and the codeword of each cell is 1, according to the cell combinations in the TDRA table, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then the maximum number of HARQ bits corresponding to cell1, cell2, and cell3 are 6, 2, and 4, respectively. Therefore, the number of bits for the determined HARQ codebook feedback is 6 + 2 + 4 = 12.

[0095] For example, if the cell set configured by the network-side equipment includes {cell1, cell2, cell3}, and HARQ spatial bundling and time bundling are not configured, and cell2 is configured with 2 codewords, while cell1 and cell3 are configured with 1 codeword each, then according to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of feedback bits for cell1, cell2, and cell3 are 6, 2*2, and 4 respectively. Thus, the determined maximum number of feedback bits is 6+4+4=14.

[0096] For example, if the cell set configured by the network-side equipment includes {cell1, cell2, cell3}, and HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, while cell1 and cell3 are configured with 1 codeword each, and cell1 is configured with time bundling, and the number of groups is 2, then according to the cell combinations in the TDRA table, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of feedback bits for cell1, cell2, and cell3 are 2, 2, and 4 respectively, and the determined maximum number of feedback bits is 2 + 2 + 4 = 8.

[0097] In another implementation, the second value can be the maximum value among the products of the first number and each of the second numbers. In this implementation, the number of bits fed back by the HARQ codebook is determined to be max(Xi*Y). Here, Xi is the maximum number of bits that each cell in the cell set (schedulable cells) determined according to the configured TDRA table can feed back, and Y is the maximum number of schedulable cells or the maximum number in the cell set. Using this implementation, the number of bits in the HARQ codebook is independent of the DCI field, making implementation simpler and more static. Even if a DCI is missed, it will not affect the determination of the number of bits fed back by the HARQ codebook. Even when no scheduled cell combination is configured, the number of bits fed back by the HARQ codebook can still be determined.

[0098] For example, if the cell set configured by the network-side equipment includes {cell1, cell2, cell3}, and HARQ spatial bundling and time bundling are not configured, and the codeword of each cell is 1, according to the cell combinations in the TDRA table, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then the maximum number of feedback bits corresponding to cell1, cell2, and cell3 are 6, 2, and 4, respectively. Therefore, the determined maximum number of feedback bits is 3 * 6 = 18.

[0099] For example, if the cell set configured by the network-side equipment includes {cell1, cell2, cell3}, and HARQ spatial bundling and time bundling are not configured, and cell2 is configured with 2 codewords, while cell1 and cell3 are configured with 1 codeword each, then according to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of feedback bits for cell1, cell2, and cell3 are 6, 2*2, and 4 respectively. Thus, the determined maximum number of feedback bits is 3*6 = 18.

[0100] For example, if the cell set configured by the network-side device includes {cell1, cell2, cell3}, and HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, while cell1 and cell3 are configured with 1 codeword each, and cell1 is configured with time bundling, and the number of groups is 2, then according to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Therefore, the maximum number of feedback bits for cell1, cell2, and cell3 are 2, 2, and 4 respectively, and the determined maximum number of feedback bits is 3 * 4 = 12.

[0101] In some embodiments, the terminal can determine the number of bits in the HARQ codebook feedback as a second value when no target configuration is configured, or when the first DCI field of the DCI includes an FDRA field indicating frequency domain information of the scheduled data channel, wherein the target configuration is used to configure schedulable cell combinations. This method allows the number of bits in the HARQ codebook feedback to be determined even when the network-side equipment has not configured schedulable cell combinations.

[0102] In this embodiment, the number of bits for HARQ codebook feedback can be determined based on a target configuration or at least one DCI field. The target configuration is used to configure schedulable cell combinations. The first DCI field is either a scheduling cell indication field or an FDRA field, and is used to indicate the scheduled cells. In one embodiment, when the terminal is configured with the target configuration, the number of bits for HARQ codebook feedback can be determined to be the first value mentioned above; when the terminal is not configured with the target configuration, the number of bits for HARQ codebook feedback can be determined to be the second value mentioned above. In another embodiment, when the first DCI field is a scheduling cell indication field, the number of bits for HARQ codebook feedback can be determined to be the first value mentioned above. When the first DCI field is an FDRA field, the number of bits for HARQ codebook feedback can be determined to be the second value mentioned above.

[0103] In some embodiments, there may be multiple DCIs, and the feedback information of these multiple DCIs may be fed back on the same PUCCH. Therefore, in these embodiments, the terminal determining the number of bits for HARQ codebook feedback may include: when there are multiple DCIs, determining the number of bits for HARQ codebook feedback based on at least one first DCI field in each DCI, wherein the first DCI field includes at least one of the following: a scheduling cell indication field for indicating the at least two scheduled cells, and an FDRA field for indicating the frequency domain information of the scheduled data channel. In these embodiments, when there are multiple DCIs, the number of bits for HARQ codebook feedback is determined based on at least one first DCI field in each DCI.

[0104] In some implementations, determining the number of bits of the HARQ codebook feedback based on at least one first DCI field in each DCI may include the following steps:

[0105] Step 1: Based on at least one first DCI field in each DCI, determine the first cell combination corresponding to the at least two cells scheduled by each DCI, and determine the maximum number of HARQ bits corresponding to the first cell combination of each DCI based on the configured TDRA table;

[0106] Step 2: Determine the number of bits fed back by the HARQ codebook as the maximum value among the maximum number of HARQ bits corresponding to the first cell combination of multiple DCIs.

[0107] Through the above implementation method, the scheduled cell combination is determined based on the first DCI field, and the number of bits for HARQ codebook feedback is determined based on the scheduled cell combination, which can save the overhead of feedback bits.

[0108] In the above implementation, the first DCI field includes a scheduling cell indication field or an FDRA field. The scheduling cell indication field determines a first cell combination corresponding to at least two scheduled cells. The configured FDRA table determines the maximum number of HARQ bits Z that can be fed back for the scheduled cell combination indicated by the first DCI field for each DCI. The number of bits fed back by the HARQ codebook is the maximum value max(Z) among the maximum number of HARQ bits determined based on each DCI.

[0109] For example, if the scheduled cell combination 1 determined by the first DCI field of DCI 1 is {cell1, cell2}, and the scheduled cell combination 2 determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination in the current PUCCH feedback is 2. When HARQ spatial bundling and time bundling are not configured, and the codeword of each cell is 1, according to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then, the maximum number of feedback bits corresponding to combination 1 and combination 2 are 6+1 and 6+4 respectively. Therefore, the determined number of bits fed back by the HARQ codebook is the maximum value of the maximum number of feedback bits corresponding to combination 1 and combination 2: 10.

[0110] For example, if the combination of scheduled cells determined by the first DCI field of DCI 1 is {cell1, cell2}, and the combination of scheduled cells determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination reported by the current PUCCH is 2. When HARQ spatial bundling and time bundling are not configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword each, according to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Then the maximum number of feedback bits corresponding to combination 1 and combination 2 are max{4+2*2, 6+1*2} = 8 and 6+4 = 10, respectively. Therefore, the determined number of HARQ codebook feedback bits is the maximum value of the maximum number of feedback bits corresponding to combination 1 and combination 2: 10.

[0111] For example, if the combination of scheduled cells determined by the first DCI field of DCI 1 is {cell1, cell2}, and the combination of scheduled cells determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination reported by the current PUCCH is 2. When HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, and cells1 and 3 are configured with 1 codeword each, and cell1 is configured with time bundling, the number of groups is 2. According to the cell combinations in TDRAtable, there are {4 PDSCHs for cell1, 2 PDSCHs for cell2}, {6 PDSCHs for cell1, 1 PDSCH for cell2}, and {6 PDSCHs for cell1, 4 PDSCHs for cell3}. Then the maximum number of feedback bits corresponding to combination 1 and combination 2 are max{2+2, 2+1} = 4 and 6+4 = 10, respectively. Therefore, the determined number of HARQ codebook feedback bits is the maximum value of the maximum number of feedback bits corresponding to combination 1 and combination 2: 10.

[0112] In another implementation, determining the number of bits of the HARQ codebook feedback based on at least one first DCI field in each DCI may include the following steps:

[0113] Step 1: Determine the first cell combination corresponding to the at least two cells scheduled by each DCI based on at least one first DCI domain in each DCI;

[0114] Step 2, the terminal determines that the number of bits fed back by the HARQ codebook is the product of the third number and the fourth number, wherein the third number is the number of cells included in the second cell combination, the fourth number is the maximum value of the number of HARQ bits corresponding to each cell determined according to the configured TDRA table, and the second cell combination is the cell combination with the largest number of cells included in each of the first cell combinations scheduled by the DCI.

[0115] In the above implementation, the first DCI field includes a scheduling cell indication field or an FDRA field. The scheduling cell indication field determines the first cell combination corresponding to at least two scheduled cells. The number of bits fed back by the HARQ codebook is max(Y)*max(X), where Y is the number of cells included in the first cell combination of each DCI scheduling, and X is the maximum number of HARQ bits corresponding to each cell determined according to the TDRA table.

[0116] For example, if the combination of scheduled cells determined by the first DCI field of DCI 1 is {cell1, cell2}, and the combination of scheduled cells determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination in the current PUCCH feedback is 2. When no spatial bundling and time bundling of HARQ are configured, and the codeword of each cell is 1, according to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Therefore, the maximum number of HARQ feedback bits corresponding to cell1, cell2, and cell3 are 6, 2, and 4 respectively, and the determined number of bits for HARQ codebook feedback is 6*2.

[0117] For example, if the combination of scheduled cells determined by the first DCI field of DCI 1 is {cell1, cell2}, and the combination of scheduled cells determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination in the current PUCCH feedback is 2. When no spatial bundling and time bundling of HARQ are configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword, according to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then the maximum number of HARQ feedback bits corresponding to cell1, cell2, and cell3 are 6, 4, and 4 respectively, and the determined number of HARQ codebook feedback bits is 6*2.

[0118] For example, if the combination of scheduled cells determined by the first DCI field of DCI 1 is {cell1, cell2}, and the combination of scheduled cells determined by the first DCI field of DCI 2 is {cell1, cell3}, then the maximum number of cells corresponding to the most scheduled cell combination in the current PUCCH feedback is 2. When HARQ spatial bundling and time bundling are configured, and cell2 is configured with 2 codewords, and cell1 and cell3 are configured with 1 codeword, and cell1 is configured with time bundling, the number of groups is 2. According to the cell combinations in TDRAtable, there are {4 PDSCHs of cell1, 2 PDSCHs of cell2}, {6 PDSCHs of cell1, 1 PDSCH of cell2}, and {6 PDSCHs of cell1, 4 PDSCHs of cell3}. Then the maximum number of feedback bits corresponding to cell1, cell2, and cell3 are 2, 2, and 4, respectively. Therefore, the number of bits determined for HARQ codebook feedback is 4*2 = 8.

[0119] In the above embodiments, the number of HARQ bits corresponding to each cell is determined by at least one of the following methods:

[0120] Method 1: When the terminal is configured with Spatial Bundling Feedback HARQ, the number of HARQ bits corresponding to each cell is the maximum number of data channels that the cell can schedule or the maximum number of Transport Block Groups (TBGs) that the cell can schedule. In this method, when Spatial Bundling Feedback HARQ is configured, the number of HARQ bits corresponding to each cell is the maximum number of PUSCH / PDSCHs or TBGs that can be scheduled.

[0121] Method 2: When the terminal is not configured with Spatial Bundling Feedback (HARQ), for cells without two codewords, the number of HARQ bits corresponding to the cell is the maximum number of data channels that the cell can schedule or the maximum number of transport block groups that the cell can schedule. For cells with two codewords, the number of bits that the cell can feed back is twice the maximum number of data channels that the cell can schedule or twice the maximum number of transport block groups that the cell can schedule. In this method, when spatial bundling is not configured, for cells without two codewords, the corresponding number of feedback bits is the maximum number of PUSCH / PDSCHs or TBGs that can be scheduled; for cells with two codewords, the corresponding number of feedback bits is 2 * the maximum number of PUSCH / PDSCHs or TBGs that can be scheduled.

[0122] Method 3: For cells configured with Time-Bundled Feedback (HARQ), the number of HARQ bits corresponding to the cell is the maximum number of transport block groups that the cell can schedule. For cells not configured with Time-Bundled Feedback (HARQ), the number of bits that the cell can feed back is the maximum number of data channels that the cell can schedule. In this method,

[0123] When a cell is configured with timebundling feedback HARQ, the number of TBGs is used; when timebundling feedback HARQ is not configured, the number of PUSCH / PDSCHs is used.

[0124] It should be noted that the number of HARQ bits corresponding to a cell can be determined by using one of the methods one to three above, or by combining at least two of the above methods. For example, the number of HARQ bits corresponding to a cell can be determined by combining method one with method three above, or by combining method two with method three above.

[0125] In some embodiments, when a terminal feeds back HARQ, if the data channel scheduled by the DCI is a Physical Downlink Shared Channel and the DCI includes at least one block of a third DCI field containing a secondary cell sleep indication, the terminal feeds back feedback information of the secondary cell sleep indication at a determined sorting position. The feedback information includes one of the following: a 1-bit ACK message, W bits of non-ACK message, or a 1-bit ACK message plus W-1 bits of non-ACK message, where W is the number of HARQ bits corresponding to the target cell, and the target cell is the cell corresponding to at least one block of the third DCI field. Optionally, the third DCI field is at least one of the following: FDRA field, NDI field, RV field, MCS field, HARQ process number, or antenna port field.

[0126] In the above embodiments, when the DCI simultaneously schedules PDSCH and indicates secondary cell dormancy, the feedback for the SCell dormancy indication can be fed back as 1 bit ACK or W bit NACK at a specified ordering position. The ordering method of the HARQ feedback bits of multiple cells scheduled by each DCI can be as follows:

[0127] First, sort according to the codewords of PDSCH.

[0128] Second, for the same {serving cell, PDCCH monitoring occasion}, sort according to the start time of PDSCH reception.

[0129] Third, sort by serving cell index in ascending order.

[0130] Where W represents the number of feedback bits corresponding to the cell as determined by the corresponding SLIV. In the above embodiment, for the secondary cell sleep indication, after the terminal sends back 1 bit ACK, it can fill the corresponding SLIV position with W-1 bits of NACK, or fill the effective bits after the actual feedback with NACK bits.

[0131] For example, if a cell set has two cells, and the DCI schedules a PDSCH on cell 1 and indicates dormancy on cell 2, then the FDRA on cell 1 is valid, and the FDRA field on cell 1 is invalid. Furthermore, if cell 2 schedules two PDSCHs and is configured with dual codewords, then the feedback order is: ACK feedback for the dormancy indication on cell 1, HARQ-ACK feedback for TB1 on cell 2, and HARQ-ACK feedback for TB2 on cell 2.

[0132] If the total number of feedback bits is 6 bits, then the feedback is ACK for dormancy, HARQ-ACK / NACK for TB 1 in cell2, HARQ-ACK / NACK for TB 2 in cell2, and padding bit (NACK, NACK, NACK).

[0133] Alternatively, when cell1's TDRA indicates two corresponding SLIVs, the feedback is ACK / NACK, ACK / NACK, ACK for dormancy, padding bit (NACK), HARQ-ACK / NACK for TB 1 in cell2, HARQ-ACK / NACK for TB 2 in cell2, padding bit (NACK,NACK).

[0134] Through the technical solutions provided in the embodiments of this application, DCI can schedule multiple cells and, for at least one of the cells, schedule multiple data channels of that cell, and determine the number of bits in the second DCI field of the DCI and the feedback of the HARQ codebook corresponding to the DCI, thereby enabling the terminal and network-side equipment to have a consistent understanding during the communication process.

[0135] Based on the same technical concept, this application also provides a signaling transmission method. This signaling transmission method is executed by a network-side device corresponding to the above-described signaling acquisition method, and has the same or corresponding implementation methods as the above-described signaling acquisition method.

[0136] It should be noted that the following embodiments only describe the operation of the network-side device. For other matters not covered, please refer to the relevant descriptions of methods 200 to 300 above.

[0137] Figure 4 shows a schematic flowchart of a signaling transmission method provided in an embodiment of this application. This method 400 can be executed by a network-side device. In other words, the method can be executed by software or hardware installed on the network-side device. As shown in Figure 4, the method mainly includes the following steps.

[0138] S410, the network-side device sends a DCI to the terminal, wherein the DCI is used to schedule at least two cells, and at least one of the at least two cells includes multiple data channels.

[0139] In some embodiments, before the network-side device sends the DCI to the terminal, the method further includes: the network-side device determining the number of bits of a second DCI field of the DCI based on at least one first DCI field of the DCI, wherein the first DCI field includes at least one of the following: a scheduling cell indication field for indicating the at least two scheduled cells, a frequency domain resource allocation (FDRA) field for indicating frequency domain information of the scheduled data channel, and a time domain resource allocation (TDRA) field for indicating time domain information of the scheduled data channel, and the second DCI field includes at least one of the following: a redundancy version (RV) field and a new data indication (NDI) field.

[0140] In some embodiments, the network-side device determines the number of bits in the second DCI field of the DCI based on at least one first DCI field of the DCI, including:

[0141] When the first DCI domain includes the scheduling cell indication domain and the TDRA domain, the network-side device determines that the second DCI domain includes N1 first bit blocks, each first bit block containing Mi bits, where N1 is the number of the at least two scheduled cells determined based on the scheduling cell indication domain, and Mi is the number of data channels scheduled in each scheduled cell determined according to the scheduling cell indication domain and the TDRA domain.

[0142] In some embodiments, the network-side device determines the number of bits in the second DCI field of the DCI based on at least one first DCI field of the DCI, including:

[0143] When the first DCI field includes the scheduling cell indication field, the network-side device determines that the second DCI field includes N1 second bit blocks, each second bit block containing M2 bits, where N1 is the number of the at least two cells to be scheduled determined based on the scheduling cell indication field, and M2 is the maximum number of data channels that can be scheduled for the first cell combination determined according to the scheduling cell indication field and the configured TDRA table, where the first cell combination is the cell combination corresponding to the at least two cells to be scheduled.

[0144] In some embodiments, the network-side device determines the number of bits in the second DCI field of the DCI based on at least one first DCI field of the DCI, including:

[0145] When the first DCI field includes the FDRA field and the FDRA field indicates whether a cell is scheduled, the network-side device determines that the second DCI field includes N2 third bit blocks, each third bit block containing the number of bits Mi', where N2 is the maximum number of schedulable cells determined according to the configuration of the network-side device, and Mi' is the maximum number of data channels that each schedulable cell can be scheduled according to the configured TDRA table.

[0146] In some embodiments, after the network-side device sends DCI to the terminal, the method further includes:

[0147] The network-side device receives the HARQ codebook sent by the terminal;

[0148] The network-side device determines the number of bits fed back from the HARQ codebook;

[0149] The network-side device obtains the feedback information sent by the terminal from the HARQ codebook based on the number of bits fed back from the HARQ codebook.

[0150] In some embodiments, the network-side device determines the number of bits fed back from the HARQ codebook, including:

[0151] The network-side device determines the number of bits fed back by the HARQ codebook as a first value, wherein the first value is one of the following:

[0152] The first value is the maximum value of the number of HARQ bits corresponding to each cell combination that can be scheduled, wherein the number of HARQ bits corresponding to each cell combination that can be scheduled is the sum of the number of HARQ bits corresponding to each cell in each cell combination determined based on the configured TDRA table;

[0153] The first value is the maximum value among the maximum number of HARQ bits corresponding to each cell combination that can be scheduled, wherein the maximum number of HARQ bits corresponding to the cell combination is the sum of the maximum number of HARQ bits corresponding to each cell in each cell combination determined based on the configured TDRA table.

[0154] In some embodiments, the network-side device determines the number of bits fed back from the HARQ codebook, including:

[0155] The network-side device determines the number of bits fed back by the HARQ codebook as a second value, wherein the second value is one of the following:

[0156] The second value is the sum of the second numbers corresponding to the first number of cells;

[0157] The second value is the maximum value among the products of the first number and each of the second numbers;

[0158] Wherein, the first number is the maximum number of at least two cells that can be scheduled, or the first number is the maximum number of cells contained in the configured cell set, and the second number is the maximum number of HARQ bits corresponding to each of the first number of cells determined according to the configured TDRA table.

[0159] In some embodiments, the network-side device determines the number of bits fed back from the HARQ codebook as a second value, including:
