1. A method comprising:
receiving, by a first user equipment (UE) from a base station, a signaling comprising indication of a plurality of time-frequency resources and an indicator indicating a time gap;
performing, by the first UE, a plurality of transmissions of a transport block (TB) to a second UE using the plurality of time-frequency resources, respectively;
for each of the plurality of transmissions, monitoring, by the first UE, a hybrid automatic repeat request (HARQ) feedback from the second UE, using a physical sidelink feedback channel (PSFCH) resource, wherein each PSFCH resource belongs to a plurality of PSFCH resources; and
transmitting, by the first UE to the base station, a HARQ feedback report signal based on the plurality of HARQ feedback or absence thereof, in a physical uplink control channel (PUCCH), using a single PUCCH resource determined based on the time gap from a last one of the plurality of PSFCH resources.
