Abstract

Apparatus and methods for channel access in an Unlicensed (UL) Sidelink (SL) communication system. In one embodiment, a relay UE triggers a listen-before-talk (LBT) process requesting to access first resources for transmission of data to a base station (BS), or reception of data from the BS. In response to the LBT, the relay UE receives a first grant that indicates the first resources for the transmission of data to a base station (BS), or reception of data from the BS. The relay UE receives from one or more UEs which are in a first set, wherein the first set of UEs are in communication range of the first UE, requests to access second resources for transmission or reception of data between the first UE, and the one or more UEs in the first set. Finally, the relay UE transmits grants of the second resources, to the one or more UEs of the first set, wherein the second resources include the remaining part of the first resources not used by the first UE.
