1. A user equipment (UE) for transmitting a hybrid automatic repeat request (HARQ) feedback, the UE comprising:
one or more non-transitory computer-readable media storing one or more computer-executable instructions; and
at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor configured to execute the one or more computer-executable instructions to cause the UE to:
receive, from a base station (BS), a physical uplink control channel (PUCCH) configuration for configuring a PUCCH, the PUCCH configuration indicating a specific PUCCH format of the PUCCH and whether a sidelink (SL) HARQ feedback is allowed to be transmitted on the PUCCH;
generate a first HARQ feedback in response to first data received from the BS via a physical downlink shared channel (PDSCH);
generate a second HARQ feedback in response to second data received from another UE via a physical sidelink shared channel (PSSCH); and
transmit, to the BS, uplink control information (UCI) including at least a portion of the first HARQ feedback and at least a portion of the second HARQ feedback via the PUCCH in a case that the PUCCH configuration indicates that the SL HARQ feedback is allowed to be transmitted on the PUCCH and a first PUCCH for the first HARQ feedback overlaps a second PUCCH for the second HARQ feedback in time domain,
wherein another portion of at least one of the first HARQ feedback and the second HARQ feedback is discarded in the UCI.
