Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may send, to a second UE, a first physical sidelink shared channel (PSSCH) transmission. The first UE may select, for a second PSSCH transmission, a PSSCH resource for which a corresponding physical sidelink feedback channel (PSFCH) resource does not collide with one of a plurality of PSFCH transmissions in accordance with a repetition factor associated with the first PSSCH transmission. The first UE may send, to the second UE, the second PSSCH transmission via the PSSCH resource. Numerous other aspects are described.
