1. A method performed by a user equipment (UE), the method comprising:
receiving a configuration for multiple hybrid automatic repeat request (HARQ) process-based HARQ-acknowledgement (HARQ-ACK) codebooks including i) a first HARQ process-based HARQ-ACK codebook related to all HARQ processes configured for the UE and ii) a second HARQ process-based HARQ-ACK codebook related to a part of the HARQ processes configured for the UE;
receiving a configuration for enabling multiplexing of uplink transmissions of different priorities;
receiving scheduling information related to a first uplink channel for transmission of first HARQ-ACK information;
receiving downlink control information including a request for transmission of second HARQ-ACK information;
determining the second HARQ-ACK information based on the downlink control information;
determining a second uplink channel for transmission of the second HARQ-ACK information based on the downlink control information;
based on i) the first uplink channel and the second uplink channel overlapping in time and ii) the first HARQ-ACK information having a high priority:
dropping the transmission of the first HARQ-ACK information and transmitting the second HARQ-ACK information, based on the second HARQ-ACK information being the first HARQ process-based HARQ-ACK codebook, and
multiplexing the second HARQ-ACK information with the first HARQ-ACK information, based on the second HARQ-ACK information being the second HARQ process-based HARQ-ACK codebook, and
based on i) the first uplink channel and the second uplink channel overlapping in time and ii) the first HARQ-ACK information having a low priority:
dropping the transmission of the first HARQ-ACK information and transmitting the second HARQ-ACK information, based on the second HARQ-ACK information being the first HARQ process-based HARQ-ACK codebook, and
multiplexing the second HARQ-ACK information with the first HARQ-ACK information, based on the second HARQ-ACK information being the second HARQ process-based HARQ-ACK codebook.
