[0046] The following is a description of the Type 2 codebook generation method disclosed in this application:

[0047] First, the proper nouns and abbreviations that may be involved in this application are explained:

[0048] PUCCH: Physical Uplink Control Channel, physical uplink control channel.

[0049] MBS: Multi-cast or Broadcast service.

[0050] PDSCH: Physical Downlink Shared Channel, downlink physical shared channel.

[0051] SPS PDSCH: semi-persistent scheduling PDSCH, semi-persistently scheduled PDSCH.

[0052] TB: Transport Block.

[0053] CBG: Coded Block Group, coded block group.

[0054] See also Figure 2 , Figure 2 A flow chart of a Type 2 codebook generation method provided in an embodiment of the present application. The Type 2 codebook generation method comprises the following steps:

[0055] 201: Obtain a transport block (TB) level codebook and a coded block group (CBG) level codebook of a unicast service, and obtain a transport block level codebook of a multicast or broadcast service MBS.

[0056] In an optional implementation, the unicast and MBS are carried on the same physical uplink control channel.

[0057] 202: Generate a Type 2 codebook according to the transport block level codebook and coding block group level codebook of unicast and the transport block level codebook of MBS.

[0058] In this embodiment, the TB-level codebook of unicast and the CBG-level codebook, as well as the TB-level codebook of MBS, can be combined to obtain the Type2 codebook. Exemplarily, the TB-level codebook of unicast and the TB-level codebook of MBS can be generated first, and then the CBG-level codebook of unicast can be placed behind the TB-level codebook of unicast and the TB-level codebook of MBS. That is, in the Type2 codebook, the TB-level codebook of unicast and the TB-level codebook of MBS are located before the CBG-level codebook of unicast. The Type2 codebook can be expressed by formula ①:

[0059] Type2=TB level(unicast)+TB level(MBS)+CBGlevel(unicast)…………①

[0060] Among them, TB level (unicast) represents the TB level codebook of unicast, TB level (MBS) represents the TB level codebook of MBS, and CBG level (unicast) represents the CBG level codebook of unicast.

[0061] In this embodiment, the TB-level codebook of service A may include: transmission block-level physical downlink channel reception and / or transmission block-level semi-static scheduling resource release (TB-level PDSCH reception and / or TB-level SPS release) of service A, and transmission block-level semi-static scheduling resource reception (TB-level SPS reception) of service A. The CBG-level codebook of service A may include: coding block group-level downlink physical shared channel reception (CBG-level PDSCH reception) of service A. Among them, service A can be unicast or MBS.

[0062] Based on this, in this implementation manner, in the TB-level codebook of unicast and the TB-level codebook of MBS in the Type2 codebook in the above formula ①, the TB-level SPS reception of unicast is located after the TB-level PDSCH reception and / or TB-level SPS release of unicast; the TB-level PDSCH reception and / or TB-level SPS release of MBS is located after the TB-level SPS reception of unicast; the TB-level SPS reception of MBS is located after the TB-level PDSCH reception and / or TB-level SPS release of MBS, such as Figure 3 That is, the Type2 codebook can be further expressed by formula ②:

[0063] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+unicastSPS reception+MBS TBlevel PDSCH reception(and / or SPS release)+MBS SPSreception+unicast CBG based reception…………②

[0064] Among them, unicast TBlevel PDSCH reception (and / or SPS release) means unicast TB-level PDSCH reception and / or TB-level SPS release, unicast SPS reception means unicast TB-level SPS reception, MBS TBlevel PDSCH reception (and / or SPS release) means MBS TB-level PDSCH reception and / or TB-level SPS release, MBS SPS reception means MBS TB-level SPS reception, unicast CBG based reception means unicast CBG-level PDSCH reception.

[0065] In an optional implementation, in the TB-level codebook of unicast and the TB-level codebook of MBS in the Type2 codebook in the above formula ①, the TB-level PDSCH reception and / or TB-level SPS release of MBS is located after the TB-level PDSCH reception and / or TB-level SPS release of unicast; the TB-level SPS reception of unicast is located after the TB-level PDSCH reception and / or TB-level SPS release of MBS; the TB-level SPS reception of MBS is located after the TB-level SPS reception of unicast, such as Figure 4 That is, the Type2 codebook can also be expressed by formula ③:

[0066] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+MBSTBlevel PDSCH reception(and / or SPS release)+unicast SPS reception+MBS SPSreception+unicast CBG based reception…………③

[0067] In an optional implementation, in the TB-level codebook of unicast and the TB-level codebook of MBS in the Type2 codebook in the above formula ①, the TB-level PDSCH reception and / or TB-level SPS release of MBS is located after the TB-level PDSCH reception and / or TB-level SPS release of unicast; the TB-level SPS reception of unicast and the TB-level SPS reception of MBS are located after the TB-level PDSCH reception and / or TB-level SPS release of MBS, such as Figure 5 As shown. Among them, the arrangement order of the sub-items in the TB-level SPS reception of unicast and the sub-items in the TB-level SPS reception of MBS are intertwined. That is, the Type2 codebook can also be expressed by formula ④:

[0068] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+MBSTBlevel PDSCH reception(and / or SPS release)+SPS reception across unicast andMBS SPS reception+unicast CBG based reception…………④

[0069] Among them, SPS reception across unicast and MBS SPS reception means TB-level SPS reception of unicast and TB-level SPS reception of MBS.

[0070] Specifically, the Type2 codebook in formula ② places the TB-level codebooks of MBS and unicast separately. That is, the TB-level codebook of unicast (TB-level PDSCH reception and / or TB-level SPS release, and TB-level SPS reception) is placed first, and then the TB-level codebook of MBS (TB-level PDSCH reception and / or TB-level SPS release, and TB-level SPS reception) is placed. The Type2 codebook in formula ③ and the Type2 codebook in formula ④ place the TB-level codebooks of MBS and unicast crosswise. That is, the TB-level PDSCH reception and / or TB-level SPS release of unicast is placed first, then the TB-level PDSCH reception and / or TB-level SPS release of MBS is placed, and finally the TB-level SPS reception of unicast and the TB-level SPS reception of MBS are placed.

[0071] The difference between the Type2 codebook in formula ③ and the Type2 codebook in formula ④ is that in the Type2 codebook in formula ③, the TB-level SPS reception of unicast and the TB-level SPS reception of MBS are placed separately, while in the Type2 codebook in formula ④, the TB-level SPS reception of unicast and the TB-level SPS reception of MBS are placed crosswise.

[0072] The following will use a practical example to illustrate the difference in placement of TB-level SPS reception of unicast and TB-level SPS reception of MBS for the Type2 codebook in formula ③ and the Type2 codebook in formula ④.

[0073] Specifically, see Figure 6 , Figure 6 FIG. 4 shows a transmission situation where MBS and unicast are multiplexed on the same PUCCH. Figure 6 As shown, the PUCCH includes two cells, cell0 and cell1, wherein the MBS receives a total of 4 SPSs, 2 of which are received through cell0 and 2 through cell1; the unicast receives a total of 4 SPSs, 2 of which are received through cell0 and 2 through cell1.

[0074] In the Type2 codebook in formula ③, TB-level SPS reception in all slots and all cells of unicast is generated first, and then TB-level SPS reception in all slots and all cells of MBS is placed at the back, that is, the placement order is 1324697 (10).

[0075] In the Type2 codebook in formula ④, TB-level SPS reception of all slots of unicast and all slots of MBS on cell0 is generated first, and then TB-level SPS reception of all slots of unicast and all slots of MBS on cell1 is generated, that is, the placement order is 1369247(10).

[0076] In an optional implementation, the unicast TB-level codebook may be generated first, and then the unicast CBG-level codebook may be placed after the unicast TB-level codebook, and finally, the MBS TB-level codebook may be placed after the unicast CBG-level codebook. The Type 2 codebook may be expressed by formula ⑤:

[0077] Type2=TB level(unicast)+CBGlevel(unicast)+TB level(MBS)…………⑤

[0078] In this embodiment, in the TB-level codebook of unicast in the Type2 codebook in the above formula ⑤, the TB-level PDSCH reception and / or TB-level SPS release of unicast is located before the TB-level SPS reception of unicast. In the TB-level codebook of MBS, the TB-level PDSCH reception and / or TB-level SPS release of MBS is located before the TB-level SPS reception of MBS, such as Figure 7 That is, the Type 2 codebook can be further expressed by formula ⑥:

[0079] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+unicastSPS reception+unicast CBG based reception+MBS TBlevel PDSCH reception(and / orSPS release)+MBS SPS reception………⑥

[0080] In an optional implementation, the TB-level SPS reception of unicast in the Type2 codebook in the above formula ⑤ is located after the TB-level PDSCH reception and / or TB-level SPS release of unicast; the TB-level SPS reception of MBS is located after the TB-level SPS reception of unicast; the CBG-level PDSCH reception of unicast is located after the TB-level SPS reception of MBS; the TB-level PDSCH reception and / or TB-level SPS release of MBS is located after the CBG-level PDSCH reception of unicast, such as Figure 8 That is, the Type2 codebook can also be expressed by formula ⑦:

[0081] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+unicastSPS reception+MBS SPS reception+unicast CBG based reception+MBS TBlevel PDSCHreception(and / or SPS release)………⑦

Among them, the arrangement order of the sub-items in the TB-level SPS reception of unicast and the sub-items in the TB-level SPS reception of MBS are intertwined. That is, the Type2 codebook can also be expressed by formula ⑧:

[0083] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+SPSreception acrossunicast and MBS SPS reception+unicast CBG based reception+MBSTBlevel PDSCH reception(and / or SPS release)…………⑧

[0084] Specifically, the difference between the Type2 codebook in formula ⑥, the Type2 codebook in formula ⑦, and the Type2 codebook in formula ⑧ is similar to the difference between the Type2 codebook in formula ②, the Type2 codebook in formula ③, and the Type2 codebook in formula ④, and will not be repeated here.

[0085] In addition, in an optional implementation, the coding block group level codebook of the MBS may also be obtained. Based on this, in step 202, the Type 2 codebook may be obtained by combining the TB level codebook and CBG level codebook of the unicast, and the TB level codebook and CBG level codebook of the MBS.

[0086] For example, the TB-level codebook of unicast and the TB-level codebook of MBS can be generated first, and then the CBG-level codebook of unicast is placed behind the TB-level codebook of unicast and the TB-level codebook of MBS, and finally, the CBG-level codebook of MBS is placed behind the CBG-level codebook of unicast. That is, the Type2 codebook can be expressed by formula ⑨:

[0087] Type2=TB level(unicast)+TB level(MBS)+CBGlevel(unicast)+CBGlevel(MBS)…………⑨

[0088] Based on this, in this implementation manner, in the TB-level codebook of unicast and the TB-level codebook of MBS in the Type2 codebook in the above formula ⑨, the TB-level SPS reception of unicast is located after the TB-level PDSCH reception and / or TB-level SPS release of unicast; the TB-level PDSCH reception and / or TB-level SPS release of MBS is located after the TB-level SPS reception of unicast; the TB-level SPS reception of MBS is located after the TB-level PDSCH reception and / or TB-level SPS release of MBS, such as Fig.10 That is, the Type 2 codebook can be further expressed by formula ⑩:

That is, the Type2 codebook can also be expressed by the formula express:

[0093] Type2=unicast TBlevel PDSCH reception(and / or SPS release)+MBSTBlevel PDSCH reception(and / or SPS release)+SPS reception acrossunicast andMBS SPS reception+unicast CBG based reception+CBGlevel(MBS)…………

[0094] Specifically, the Type2 codebook in formula ⑩, formula Type2 codebook and formula in The difference between the Type2 codebooks in formula ②, the Type2 codebook in formula ③ and the Type2 codebook in formula ④ is similar to the difference between the Type2 codebook in formula ②, the Type2 codebook in formula ③ and the Type2 codebook in formula ④, and will not be repeated here.
