1. A method performed by a user equipment (UE) of a communication system, the method comprising:
receiving, from a base station, first downlink control information (DCI) associated with first priority information;
receiving, from the base station, second DCI associated with second priority information;
identifying that a resource of a physical uplink control channel (PUCCH) associated with the first DCI and a resource of a physical uplink shared channel (PUSCH) associated with the second DCI overlap on a time domain;
in case that a priority of the PUCCH and a priority of the PUSCH are different based on the first priority information and the second priority information, transmitting, to the base station, one of the PUCCH and the PUSCH corresponding to a higher priority; and
in case that the priority of the PUCCH and the priority of the PUSCH are identical based on the first priority information and the second priority information, multiplexing the PUCCH and the PUSCH,
wherein the first priority information and the second priority information is obtained based on the first DCI and the second DCI,
wherein the PUCCH or the PUSCH includes information on a hybrid automatic repeat request—acknowledgement (HARQ-ACK) codebook generated based on acknowledgment information bits for a plurality of downlink data, and
wherein respective acknowledgment information bits for the plurality of downlink data are arranged in the HARQ-ACK codebook in an ascending order of cell indexes and in an ascending order of HARO process indexes corresponding to the plurality of downlink data for a same cell index.
