1. A method for wireless communication, comprising:
receiving, by a terminal from a base station, a first set of information relating to a unicast service and a second set of information relating to a plurality of multicast services, wherein each of the plurality of multicast services is associated with a separate downlink assignment index (DAI);
for each of the plurality of multicast services, constructing, by the terminal, a sub hybrid automatic repeat request (HARQ) acknowledgement (sub-HARQ-ACK) codebook based on a DAI corresponding to the each multicast service;
generating, by the terminal, a final codebook by concatenating a first codebook followed by a set of second codebooks,
wherein the first codebook is based on the first set of information,
wherein the set of second codebooks comprises the plurality of sub-HARQ-ACK codebooks;
wherein the plurality of sub-HARQ-ACK codebooks are concatenated in an order corresponding to a sequence of group radio network temporary identifier values, and
wherein the final codebook comprises a HARQ-ACK codebook;
determining, by the terminal, a physical uplink control channel (PUCCH) resource for the final codebook based on a last physical downlink control channel (PDCCH) of the unicast service, wherein the last PDCCH corresponds to the first codebook in the final codebook; and
transmitting the final codebook to the base station by the terminal using the PUCCH resource.
