Abstract

Claims (31)

1. One or more non-transitory, computer-readable media having instructions that, when executed, cause baseband circuitry to:

generate first hybrid automatic repeat request-acknowledgment (HARQ-ACK) information for a unicast downlink channel transmission based on a first set of downlink assignment indexes (DAIs) that is based on one or more unicast transmissions;

generate second HARQ-ACK information for a first group-common downlink channel transmission in a first common frequency resource (CFR) based on a second set of DAIs that is based on one or more multicast transmissions;

generate third HARQ-ACK information for a second group-common downlink channel transmission in a second CFR based on a third set of DAIs that is based on one or more multicast transmissions, wherein a counter DAI of the third set of DAIs is sequentially incremented with respect to a counter DAI of the second set of DAIs; and

construct a dynamic HARQ-ACK codebook by concatenating the first HARQ-ACK information, the second HARQ-ACK information, and third HARQ-ACK information in sequence.

2. The one or more non-transitory, computer-readable media of claim 1 , wherein the instructions, when executed, further cause the baseband circuitry to:

concatenate the first HARQ-ACK information based on the first set of DAIs and the second HARQ-ACK information based on the second set of DAIs.

3. The one or more non-transitory, computer-readable media of claim 1 , wherein the first group-common downlink channel transmission is a physical downlink shared channel (PDSCH) transmission.

4. The one or more non-transitory, computer-readable media of claim 3 , wherein the PDSCH transmission is for a multicast-broadcast service (MBS).

5. The one or more non-transitory, computer-readable media of claim 1 , wherein the first set of DAIs includes a first counter DAI and a first total DAI and the second set of DAIs includes a second counter DAI and a second total DAI.

6. A method comprising:

generating first hybrid automatic repeat request-acknowledgment (HARQ-ACK) information for a unicast downlink channel transmission based on a first set of downlink assignment indexes (DAIs) that is based on one or more unicast transmissions;

generating second HARQ-ACK information for a first group-common downlink channel transmission in a first common frequency resource (CFR) based on a second set of DAIs that is based on one or more multicast transmissions;

generating third HARQ-ACK information for a second group-common downlink channel transmission in a second CFR based on a third set of DAIs that is based on one or more multicast transmissions, wherein a counter DAI of the third set of DAIs is sequentially incremented with respect to a counter DAI of the second set of DAIs; and

constructing a dynamic HARQ-ACK codebook by concatenating the first HARQ-ACK information and the second HARQ-ACK information in sequence.

7. The method of claim 6 , wherein the method further comprises:

concatenating the first HARQ-ACK information based on the first set of DAIs and the second HARQ-ACK information based on the second set of DAIs.

8. The method of claim 6 , wherein the first group-common downlink channel transmission is a physical downlink shared channel (PDSCH) transmission.

9. The method of claim 8 , wherein the PDSCH transmission is for a multicast-broadcast service (MBS).

10. The method of claim 6 , wherein the first set of DAIs includes a first counter DAI and a first total DAI and the second set of DAIs includes a second counter DAI and a second total DAI.

11. An apparatus comprising:

baseband circuitry to:

generate a unicast downlink channel transmission;

generate a first group-common downlink channel transmission in a first common frequency resource (CFR);

generate a second group-common downlink channel transmission in a second CFR;

process a hybrid automatic repeat request-acknowledgment (HARQ-ACK) codebook that includes first HARQ-ACK information, second HARQ-ACK information, and third HARQ-ACK information concatenated in sequence, wherein the first HARQ-ACK information is for the unicast downlink channel transmission based on a first set of downlink assignment indexes (DAIs) that is based on one or more unicast transmissions, the second HARQ-ACK information is for the first group-common downlink channel transmission based on a second set of DAIs that is based on one or more multicast transmissions, and the third HARQ-ACK information is for the second group-common downlink channel transmission based on a third set of DAIs that is based on one or more multicast transmissions, wherein a counter DAI of the third set of DAIs is sequentially incremented with respect to a counter DAI of the second set of DAIs; and

interface circuitry coupled with the baseband circuitry to enable communication.

12. The apparatus of claim 11 , wherein the first HARQ-ACK information is concatenated in sequence with the second HARQ-ACK information based on the first set of DAIs and the second set of DAIs.

13. The apparatus of claim 11 , wherein the first group-common downlink channel transmission is a physical downlink shared channel (PDSCH) transmission.

14. The apparatus of claim 13 , wherein the PDSCH transmission is for a multicast-broadcast service (MBS).

15. The apparatus of claim 11 , wherein the first set of DAIs includes a first counter DAI and a first total DAI and the second set of DAIs includes a second counter DAI and a second total DAI.
