1. A method performed by a first user equipment (UE) for wireless communication, the method comprising:
receiving, from a second UE, sidelink control information (SCI) on a first interlace on a carrier, wherein the SCI schedules data transmission on one or more interlaces on the carrier and the first interlace comprises evenly-spaced resource blocks (RBs) in a frequency domain; and
transmitting, corresponding to the data transmission, a hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback on a feedback resource, wherein the feedback resource is one of multiple feedback resources indicated by the SCI based on the one or more interlaces on the carrier, and wherein a number of the multiple feedback resources is determined based on a number of interlaces dependent on subcarrier spacing of the carrier and a number of cyclic shifts.
