A method for transmitting a scheduling request includes receiving, at a relay UE and from a remote UE, a sidelink control information. The relay UE is within a coverage area of a base station. The remote UE is outside of the coverage area. The relay UE is configured to relay transmissions from the remote UE to the base station, and the sidelink control information indicates a future transmission of a data packet over a sidelink channel. A scheduling request is transmitted to a base station. A scheduling grant that indicates an uplink resource is received from the base station. A data packet over the sidelink channel is received from the remote UE.
