The invention relates to a method for scheduling radio resources for a relay user equipment (UE) serving as a relay for remote UEs. Remote data is relayed by the relay UE between the remote UEs and a radio base station (BS). A remote scheduling identification is configured for addressing remote logical channels carrying the remote data, which is received from and transmitted to the remote UEs by the Relay UE over the Sidelink channels. A relay scheduling identification is configured for addressing one or more relay logical channels carrying relay data. The relay UE receives, from the BS, a remote resource assignment, assigning radio resources to the relay UE for exchanging the remote data with the BS, the remote resource assignment being addressed to the remote scheduling identification. The relay UE further receives, from the BS, a relay resource assignment, assigning radio resources to the relay UE for exchanging the relay data with the BS, the relay resource assignment being addressed to the relay scheduling identification. The relay UE carries out uplink resources request according to different Buffer Status Reports considerations, at the relay and at the remote UEs. . Also, the relay UE carries out a mapping in uplink and downlink of sidelink channels and remote channels that takes into account the different priorities of each of the channels and ensuing different treatment on each of the interfaces. |
