In this regard, the current protocol for determining the number of bits of the hybrid automatic repeat request feedback information only considers the case where there is only unicast service in the PUCCH.

Therefore, after the introduction of the 5G standard Rel-17, there will be a situation where multiple services reuse the same PUCCH, for example, MBS and unicast reuse the same PUCCH, and the existing protocol for determining the number of bits of hybrid automatic repeat request feedback information cannot be applied to the determination of the number of bits of hybrid automatic repeat request feedback information in this case.

[0038] In the following, the user equipment (UE) will be used to refer to the terminal 120, and the method for determining the number of bits disclosed in this application will be described:

[0039] First, the proper nouns and abbreviations that may be involved in this application are explained:

[0040] PUCCH: Physical Uplink Control Channel, physical uplink control channel.

[0041] HARQ-ACK: Hybrid Automatic Repeat request-Acknowledge character, hybrid automatic repeat request feedback information.

[0042] UE: User Equipment.

[0043] DCI: Downlink Control Information, downlink control information.

[0044] URLLC: ultra-reliable low latency communications.

[0045] MBS: Multi-cast or Broadcast service.

[0046] PDSCH: Physical Downlink Shared Channel, downlink physical shared channel.

[0047] SPS PDSCH: semi-persistent scheduling PDSCH, semi-persistently scheduled PDSCH.

[0048] DAI: Downlink Assignment Indicator, downlink assignment indication.

[0049] Secondly, it should be noted that in this embodiment, the method for determining the number of bits disclosed in this application will be described by taking the case where two services multiplex the same PUCCH as an example. For the case where three services multiplex the same PUCCH, four services multiplex the same PUCCH, and other multiple services multiplex the same PUCCH, the method for determining the number of bits is similar to the method for determining the number of bits in the case where two services multiplex the same PUCCH, and will not be repeated here.

[0050] See also Figure 2 , Figure 2 A flowchart of a method for determining the number of bits provided in an embodiment of the present application. The method for determining the number of bits comprises the following steps:

[0051] 201: Obtain service information of a first service and service information of a second service.

[0052] In this embodiment, the first service and the second service are carried on the same physical uplink control channel. In other words, the DCI corresponding to the first service and the second service multiplex the same PUCCH for feedback. At the same time, the first service and the second service can be the same service or different services. For example, the first service can be a unicast service, and the second service can also be a unicast service; or, the first service can be a unicast service, and the second service can be an MBS; or, the first service can be an MBS, and the second service can also be an MBS.

[0053] In this implementation, the physical uplink control channel PUCCH may include one or more cells. Based on this, this implementation provides a method for acquiring service information of a first service, such as Figure 3 As shown, including:

[0054] 301: Obtain a first amount of downlink control information corresponding to a first service.

[0055] In this implementation manner, each piece of downlink control information in the first amount of downlink control information is fed back via a physical uplink control channel, that is, the first amount of DCIs are multiplexed on the same PUCCH for feedback.

[0056] Since the DCI of unicast service is scrambled by C-RNTI, while the DCI of MBS is scrambled by G-RNTI (Group-RNTI), their scrambling parameters are different. At the same time, even for the same service, the scrambling parameters of different sub-services are different. For example, the scrambling parameter of unicast 1 is A, and the scrambling parameter of unicast 2 is B, and A and B are different.

[0057] Based on this, in this implementation, by obtaining all DCIs fed back through the same PUCCH, each DCI in all DCIs can be descrambled to obtain a first parameter (i.e., scrambling parameter) corresponding to each DCI. Then, the first parameter corresponding to each DCI is compared with the scrambling parameter of the first service. If the two are the same, it means that the corresponding DCI is the DCI corresponding to the first service. In this way, the DCI corresponding to the first service can be found in all DCIs, and then its number can be counted to obtain the first number.

[0058] In an optional implementation, after obtaining all DCIs fed back through the same PUCCH, all DCIs can be sorted in chronological order, and the DCIs in the sequence can be descrambled from back to front until the DCI corresponding to the first service is found. The DCI is the last DCI fed back by the first service in the PUCCH. By extracting the value of the counter DAI in the DCI, the first quantity can be obtained, that is, the first quantity of downlink control information corresponding to the first service is equal to the DAI value of the last DCI fed back by the first service in the PUCCH. Specifically, when the PUCCH is a single cell, the DAI is the counter DAI, and when the PUCCH is a multi-cell, the DAI is the total DAI. In this way, the first quantity of downlink control information corresponding to the first service can be quickly obtained, thereby improving the efficiency of determining the number of bits.

[0059] 302: Determine a second amount of downlink control information corresponding to the first service received by the user equipment.

[0060] Similarly, each downlink control information in the second amount of downlink control information is fed back through a physical uplink control channel, that is, the second amount of DCI multiplexes the same PUCCH for feedback. At the same time, the method for determining the second amount of downlink control information corresponding to the first service received by the user equipment is similar to the method for obtaining the first amount of downlink control information corresponding to the first service in step 301, and is not repeated here.

[0061] For a PUCCH including multiple cells, in an optional implementation, the second number of downlink control information corresponding to the first service received by the user equipment can be obtained by separately determining the number of DCIs corresponding to the first service fed back by each cell in the PUCCH and received by the user equipment, and then summing the number of DCIs corresponding to the first service fed back by each cell.

[0062] Specifically, the second amount of downlink control information corresponding to the first service received by the user equipment can be expressed by formula ①:

[0063]

[0064] Among them, U DAI，c represents the number of DCIs corresponding to the first service received by the user equipment and fed back by the cell c, Indicates the number of cells included in the PUCCH.

[0065] 303: Determine the number of transport blocks transmitted by the dynamic downlink data channel corresponding to the first service and received by the user equipment in each of the one or more cells.

[0066] 304: Determine the amount of downlink control information indicating the release of semi-persistent scheduling resources corresponding to the first service received by the user equipment in each cell.

[0067] In this embodiment, the sum of the number of transmission blocks transmitted by the dynamic downlink data channel corresponding to the first service received by the user equipment in each cell in step 303 and the number of downlink control information indicating the release of semi-static scheduling resources corresponding to the first service received by the user equipment in each cell in step 304 can be regarded as the total number of transmission blocks corresponding to the first service received by the user equipment in the time period from the first DCI to the last DCI from the same PUCCH.

[0068] Exemplarily, this time period may be divided into multiple slots, and some monitoring opportunities are configured in each slot to detect the number of transport blocks corresponding to the first service received by the user equipment from the PUCCH in the slot. Specifically, monitoring of a certain slot may be achieved by configuring a monitoring sequence. For example, Figure 4 A schematic diagram of a monitoring sequence is shown, such as Figure 4 As shown, the monitoring sequence consists of 14 bits, corresponding to 14 symbols. A sequence of 1 indicates a monitoring opportunity, and the value of CORESET-time-duration is the monitoring duration.

[0069] Therefore, the number of transmission blocks corresponding to the first service from the PUCCH received by the user equipment in this time period can be obtained by obtaining the number of transmission blocks corresponding to the first service from the PUCCH received by the monitored user equipment in each monitoring period m, and then summing the corresponding numbers for all monitoring periods.

[0070] Specifically, the number of transport blocks corresponding to the first service received by the user equipment from the PUCCH in each cell can be expressed by formula ②:

[0071]

[0072] Among them, N k,c represents the number of transport blocks transmitted by the dynamic downlink data channel corresponding to the first service received by the user equipment in the cell c, N y,c represents the number of downlink control information indicating the release of semi-persistent scheduling resources corresponding to the first service received by the user equipment in cell c, N q，c represents the number of transport blocks corresponding to the first service from the PUCCH received by the user equipment in the cell c, M represents the total number of monitoring opportunities, It indicates the number of transport blocks corresponding to the first service received by the user equipment from the PUCCH monitored at monitoring time m.

[0073] 305: Determine the number of transport blocks transmitted by the semi-static downlink data channel corresponding to the first service and received by the user equipment in each cell.

[0074] In this embodiment, the method for the user equipment to obtain the number of transmission blocks transmitted by the semi-static downlink data channel corresponding to the first service in each cell is similar to the method for obtaining the first number of downlink control information corresponding to the first service in step 301, and will not be repeated here.

[0075] 306: The first number of downlink control information corresponding to the first service, the second number of downlink control information corresponding to the first service, the number of transmission blocks transmitted by the dynamic downlink data channel corresponding to the first service received by the user equipment in each cell, the number of downlink control information indicating the release of semi-static scheduling resources corresponding to the first service received by the user equipment in each cell, and the number of transmission blocks transmitted by the semi-static downlink data channel corresponding to the first service received by the user equipment in each cell are taken as the service information of the first service.

[0076] In this implementation, the method for determining the service information of the second service is similar to the method for determining the service information of the first service in steps 301 - 306 , and will not be described in detail herein.

[0077] 202: Obtain the number of bits of hybrid automatic repeat request feedback information of a physical uplink control channel according to the configuration information, the service information of the first service and the service information of the second service.

[0078] In this implementation, the configuration information is used to record configuration parameters of channels for transmitting the first service and the second service. Exemplarily, the configuration information may include configuration information of the PUCCH and configuration information of the PDSCH.

[0079] In this embodiment, a method for obtaining the number of bits of hybrid automatic repeat request feedback information of a physical uplink control channel according to configuration information, service information of a first service and service information of a second service is provided, such as Figure 5 As shown, the method includes:

[0080] 501: Determine a first bit quantity of hybrid automatic repeat request feedback information of a first service according to configuration information and service information of a first service.

[0081] In this embodiment, the bit width of the first indication information of the DCI fed back in the PUCCH is first determined by the configuration information of the PUCCH in the configuration information. The first indication information is used to indicate the cumulative number of downlink control information with different data content received by the user equipment and / or the cumulative number of downlink control information indicating the release of downlink semi-static scheduling resources, for example, the counter DAI field in the DCI.

[0082] Then, the maximum number of codewords for the first configuration is determined by the first information source corresponding to the first service in the configuration information. In this embodiment, the first information source may be the configuration information (PDSCH-config) of the PDSCH, and the first configuration may be the maxNrofCodeWordsScheduledByDCI configuration. Among them, PDSCH-config is the PDSCH-config corresponding to the first service. Exemplarily, if the first service is a unicast service, the corresponding PDSCH-config is the usual PDSCH-config; if the first service is MBS, the corresponding PDSCH-config is GC-PDSCH-config.

[0083] After the above two parameters are determined, the first bit quantity of the hybrid automatic repeat request feedback information of the first service can be expressed by formula ③:

[0084]

[0085] Where x represents the bit width, Indicates the maximum number of codewords, represents the first amount of downlink control information corresponding to the first service, U DAI represents the second amount of downlink control information corresponding to the first service, N k,c represents the number of transport blocks transmitted by the dynamic downlink data channel corresponding to the first service received by the user equipment in each cell, N y,c Indicates the number of downlink control information indicating the release of semi-persistent scheduling resources corresponding to the first service received by the user equipment in each cell, N sps,crepresents the number of transport blocks transmitted by the semi-static downlink data channel corresponding to the first service and received by the user equipment in each cell, Indicates the number of cells corresponding to the physical uplink control channel.

[0086] Further, by substituting formula 1 and formula 2 into the formula, the first bit quantity of the hybrid automatic repeat request feedback information of the first service can also be expressed by formula 4:

[0087]

[0088] 502: Determine a second number of bits of hybrid automatic repeat request feedback information of the second service according to the configuration information and the service information of the second service.

[0089] In this embodiment, the method for determining the second number of bits of the hybrid automatic repeat request feedback information of the second service based on the configuration information and the service information of the second service is similar to the method for determining the first number of bits of the hybrid automatic repeat request feedback information of the first service based on the configuration information and the service information of the first service in step 501, and will not be repeated here.

[0090] 503: Obtain a third bit quantity according to the first bit quantity and the second bit quantity.

[0091] In this implementation, the third number of bits is the number of bits of hybrid automatic repeat request feedback information of the physical uplink control channel. Exemplarily, the sum of the first number of bits and the second number of bits can be used as the third number of bits.

[0092] In summary, the method for determining the number of bits provided by the present invention obtains the service information of the first service and the second service carried in the same PUCCH respectively, and then combines the configuration information and the service information of the first service and the second service to respectively determine the number of bits of the hybrid automatic repeat request feedback information of the first service and the second service. Finally, according to the number of bits of the hybrid automatic repeat request feedback information of the first service and the second service, the number of bits of the hybrid automatic repeat request feedback information of the PUCCH is determined. In this way, the number of bits of the hybrid automatic repeat request confirmation feedback of the PUCCH can be accurately determined when the first service and the second service reuse the same PUCCH.

[0093] The following is a description of the method for determining the number of bits provided in this application with reference to specific examples:

[0094] See also Figure 6 , Figure 6 FIG. 4 shows a transmission situation where MBS and unicast services are multiplexed on the same PUCCH. Figure 6As shown, the PUCCH includes two cells, cell0 and cell1, namely Before PUCCH is sent or coded, the unicast service receives a total of 5 DCIs, of which 3 are received through cell0 and 2 are received through cell1. Of the 5 DCIs of unicast services, the user equipment receives 4 and misses 1, of which 2 are received through cell0 and miss 1, and 2 are received through cell1. The unicast service also receives 1 SPS PDSCH transmission through cell0. MBS receives a total of 3 DCIs, of which 0 are received through cell0 and 3 are received through cell1. Of the 3 DCIs of MBS, the user equipment receives 2 and misses 1, of which 0 are received through cell0 and 2 are received through cell1 and miss 1. MBS also receives 1 SPS PDSCH transmission through cell1. At the same time, according to the configuration information, the maximum number of codewords configured by maxNrofCodeWordsScheduledByDCI corresponding to the unicast service is 1, and the maximum number of codewords configured by maxNrofCodeWordsScheduledByDCI corresponding to the MBS is 1. The bit width of the counter DAI field in the DCI fed back via the PUCCH is 2.

[0095] Therefore, for unicast services, the number of bits of its hybrid automatic repeat request feedback information is:

[0096]

[0097] For MBS, the number of bits of its hybrid automatic repeat request feedback information is:

[0098]

[0099] Therefore, the number of bits of the hybrid automatic repeat request feedback information of the PUCCH is:

[0100] n HARQ-ACK =n HARQ-ACK,1 +n HARQ-ACK,2 =6+4=10

[0101] Therefore, when the unicast service and the MBS multiplex the same PUCCH, the number of bits of the hybrid automatic repeat request feedback information of the PUCCH can be accurately determined.

[0102] In addition, the present application also provides a method for determining a PUCCH transmission power adjustment parameter. Specifically, the transmission power adjustment parameter can be expressed by formula ⑤:

[0103] Δ TF,b,f,c (i) = 10log10 (K1(n NARQ-ACK (i)+O SR (i)+O CSI (i)) / N RE (i))………⑤

[0104] Among them, n NARQ-ACK (i) is the number of bits of the hybrid automatic repeat request feedback information corresponding to the PUCCH at the transmission opportunity i. The method for determining the number of bits of the hybrid automatic repeat request feedback information of the PUCCH in the above steps 201-202 is similar, and will not be repeated here. SR (i) is the number of SR information bits determined by the UE at the transmission opportunity i, O CSI (i) is the number of CSI information bits determined by the UE at transmission opportunity i, N RE (i) is the number of resource elements at transmission timing i.

[0105] See also Figure 7 , Figure 7 This is a block diagram of the functional modules of a device for determining the number of bits provided in an embodiment of the present application. Figure 7 As shown, the bit quantity determining device 700 includes:

[0107] The processing module 702 is used to obtain the number of bits of the hybrid automatic repeat request feedback information of the physical uplink control channel according to the configuration information, the service information of the first service and the service information of the second service, wherein the configuration information is used to record the configuration parameters of the channel for transmitting the first service and the second service.

[0108] In an embodiment of the present invention, in terms of obtaining the number of bits of hybrid automatic repeat request feedback information of a physical uplink control channel according to the configuration information, the service information of the first service, and the service information of the second service, the processing module 702 is specifically used to:

[0109] Determine, according to the configuration information and the service information of the first service, a first bit quantity of hybrid automatic repeat request feedback information of the first service;

[0110] Determine the second bit quantity of the hybrid automatic repeat request feedback information of the second service according to the configuration information and the service information of the second service;

[0111] A third number of bits is obtained according to the first number of bits and the second number of bits, wherein the third number of bits is the number of bits of hybrid automatic repeat request feedback information of the physical uplink control channel.

[0112] In an embodiment of the present invention, the physical uplink control channel corresponds to one or more cells. Based on this, in terms of acquiring service information of the first service, the parameter determination module 701 is specifically used to:
