202: and generating a Type2 codebook according to the transport block-level codebook and the coding block group-level codebook of the unicast and the transport block-level codebook of the MBS.
In this embodiment, the TB-level codebook and the CBG-level codebook of the unified may be combined with the TB-level codebook of the MBS to obtain the Type2 codebook. For example, the TB-level codebook of the unicast and the TB-level codebook of the MBS may be generated first, and then the CBG-level codebook of the unicast is placed behind the TB-level codebook of the unicast and the TB-level codebook of the MBS. That is, in the Type2 codebook, the TB-level codebook of the unified and the TB-level codebook of the MBS precede the CBG-level codebook of the unified. The Type2 codebook can be represented by formula (1):
Type2＝TB level(unicast)+TB level(MBS)+CBGlevel(unicast)………①
wherein TB level (unified) represents a unified TB-level codebook, TB level (MBS) represents a MBS TB-level codebook, and CBGlevel (unified) represents a CBG-level codebook.
In this embodiment, the TB-level codebook for service a may include: transport block level physical downlink channel reception and/or transport block level semi-persistent scheduling resource release for service a (TB level PDSCH reception and/or TB level SPS release), and transport block level semi-persistent scheduling resource reception for service a (TB level SPS reception). The CBG-level codebook for service a may include: code block group level downlink physical shared channel reception for traffic a (CBG level PDSCH reception). Service a may be unicast or MBS.
Based on this, in the present embodiment, in the TB-level codebook of the unified TB and the TB-level codebook of the MBS in the Type2 codebook in the formula (1), the TB-level SPS of the unified is received after the TB-level PDSCH of the unified is received and/or the TB-level SPS is released; the TB-level PDSCH reception and/or the TB-level SPS release of the MBS are/is positioned after the TB-level SPS reception of the unicast; TB level SPS reception by the MBS, after TB level PDSCH reception and/or TB level SPS release by the MBS, as shown in fig. 3. That is, the Type2 codebook can be further expressed by equation (2):
Type2＝unicast TBlevel PDSCH reception(and/or SPS release)+unicast SPS reception+MBS TBlevel PDSCH reception(and/or SPS release)+MBS SPS reception+unicast CBG based reception………②
the unified TBlevel PDSCH reception (and/or SPS release) represents the TB level PDSCH reception and/or the TB level SPS release of the unified, the unified SPS reception represents the TB level SPS reception of the unified, the MBS TBlevel PDSCH reception (and/or SPS release) represents the TB level PDSCH reception and/or the TB level SPS release of the MBS, the MBS SPS reception represents the TB level SPS reception of the MBS, and the unified CBG based reception represents the CBG level PDSCH reception of the unified.
In an optional embodiment, in the TB-level codebook of the unicast and the TB-level codebook of the MBS in the Type2 codebook in the formula (1), the TB-level PDSCH reception and/or the TB-level SPS release of the MBS is located after the TB-level PDSCH reception and/or the TB-level SPS release of the unicast; the TB-level SPS reception of the unicast is positioned after the TB-level PDSCH reception and/or the TB-level SPS release of the MBS; the TB level SPS reception of the MBS is positioned after the TB level SPS reception of the unicast, as shown in FIG. 4. That is, the Type2 codebook can also be expressed by equation (3):
Type2＝unicast TBlevel PDSCH reception(and/or SPS release)+MBS TBlevel PDSCH reception(and/or SPS release)+unicast SPS reception+MBS SPS reception+unicast CBG based reception………③
in an optional embodiment, in the TB-level codebook of the unicast and the TB-level codebook of the MBS in the Type2 codebook in the formula (1), the TB-level PDSCH reception and/or the TB-level SPS release of the MBS is located after the TB-level PDSCH reception and/or the TB-level SPS release of the unicast; TB-level SPS reception of unicast and TB-level SPS reception of MBS, after TB-level PDSCH reception and/or TB-level SPS release of MBS, as shown in fig. 5. Wherein, the arrangement order of the sub-items in TB-level SPS receiving of the unicast and the sub-items in TB-level SPS receiving of the MBS are mutually crossed. That is, the Type2 codebook can also be expressed by equation (4):
Type2＝unicast TBlevel PDSCH reception(and/or SPS release)+MBS TBlevel PDSCH reception(and/or SPS release)+SPS reception acrossunicast and MBS SPS reception+unicast CBG based reception………④
wherein, the SPS reception authentication and MBS SPS reception represents TB level SPS reception of the authentication and TB level SPS reception of the MBS.
Specifically, the Type2 codebook in formula (2) is a TB-level codebook that separates MBS and unicast. That is, the TB-level codebook of the unicast (TB-level PDSCH reception and/or TB-level SPS release, and TB-level SPS reception) is placed first, and the TB-level codebook of the MBS (TB-level PDSCH reception and/or TB-level SPS release, and TB-level SPS reception) is placed next. And the Type2 codebook in formula (3) and the Type2 codebook in formula (4) are the TB-level codebooks of MBS and unicast which are placed across. Namely, TB-level PDSCH reception and/or TB-level SPS release of the unicast are firstly placed, then TB-level PDSCH reception and/or TB-level SPS release of the MBS are placed, and finally TB-level SPS reception of the unicast and TB-level SPS reception of the MBS are placed.
And the Type2 codebook in the formula (3) is different from the Type2 codebook in the formula (4) in that the TB-level SPS reception of the unicast and the TB-level SPS reception of the MBS are separately placed in the Type2 codebook in the formula (3), and the TB-level SPS reception of the unicast and the TB-level SPS reception of the MBS are alternately placed in the Type2 codebook in the formula (4).
The difference in placement of TB-level SPS reception of unicast and TB-level SPS reception of MBS in the Type2 codebook in formula (3) and the Type2 codebook in formula (4) will be explained below with a practical example.

In the Type2 codebook in formula (3), TB-level SPS receptions in all slots and all cells of the unicast are generated first, and then all slots and TB-level SPS receptions of all cells of the MBS are placed at the back, that is, the placement order is 1324697 (10).
In the Type2 codebook in equation (4), TB-level SPS receptions of all slots of the unicast and all slots of the MBS on cell0 are generated first, and TB-level SPS receptions of all slots of the unicast and all slots of the MBS on cell1 are generated again, that is, the placement order is 1369247 (10).
In an optional embodiment, the TB-level codebook of the unicast may be generated first, then the CBG-level codebook of the unicast is placed after the TB-level codebook of the unicast, and finally the TB-level codebook of the MBS is placed after the CBG-level codebook of the unicast. The Type2 codebook can be represented by formula (5):

in the present embodiment, in the TB-level codebook of the unified st in the Type2 codebook in the above formula (5), the TB-level PDSCH reception and/or the TB-level SPS release of the unified st are located before the TB-level SPS reception of the unified st. In the TB-level codebook of the MBS, TB-level PDSCH reception and/or TB-level SPS release of the MBS precedes TB-level SPS reception of the MBS, as shown in fig. 7. That is, the Type2 codebook can be further expressed by equation (6):
Type2＝unicast TBlevel PDSCH reception(and/or SPS release)+unicast SPS reception+unicast CBG based reception+MBS TBlevel PDSCH reception(and/or SPS release)+MBS SPS reception………⑥
in an alternative embodiment, the TB-level SPS reception of the unicast in the Type2 codebook in the above formula (5) is located after the TB-level PDSCH reception and/or the TB-level SPS release of the unicast; TB level SPS reception of MBS, after TB level SPS reception of unicast; CBG-level PDSCH reception of unicast, after TB-level SPS reception of MBS; the TB-level PDSCH reception and/or TB-level SPS release for MBS is located after CBG-level PDSCH reception for unicast, as shown in fig. 8. That is, the Type2 codebook can also be expressed by equation (7):

Wherein, the arrangement order of the sub-items in TB-level SPS receiving of the unicast and the sub-items in TB-level SPS receiving of the MBS are mutually crossed. That is, the Type2 codebook can also be expressed by equation (8):
Type2＝unicast TBlevel PDSCH reception(and/or SPS release)+SPS reception acrossunicast and MBS SPS reception+unicast CBG based reception+MBS TBlevel PDSCH reception(and/or SPS release)………⑧

In addition, in an alternative embodiment, a code block group level codebook of the MBS may also be obtained. Based on this, in step 202, the Type2 codebook may be obtained by combining the TB-level codebook and the CBG-level codebook of the unicast, and the TB-level codebook and the CBG-level codebook of the MBS.
For example, the TB-level codebook of the unicast and the TB-level codebook of the MBS may be generated first, then the CBG-level codebook of the unicast is placed behind the TB-level codebook of the unicast and the TB-level codebook of the MBS, and finally the CBG-level codebook of the MBS is placed behind the CBG-level codebook of the unicast. That is, the Type2 codebook can be expressed by equation (9):
Type2＝TB level(unicast)+TB level(MBS)+CBGlevel(unicast)+CBGlevel(MBS)………⑨
