Methods and apparatuses in a wireless communication system. A method of operating a UE includes: receiving configuration information for TX resource pools including at least one of a first set of resource pools or a second set of resource pools; identifying, at an RRC sub-layer, the first and second set of resource pools based on a HARQ feedback channel; selecting, at a MAC sub-layer, a logical channel to transmit SL data, wherein the logical channel includes a highest priority among multiple logical channels using an LCP function; determining, at the MAC sub-layer, whether the logical channel is configured with the HARQ feedback channel; selecting, at the MAC sub-layer, a TX resource pool from the first set of resource pools based on a determination that the logical channel is configured with the HARQ feedback channel; and transmitting the SL data based on the TX resource pool.
