IMPROVED BEARER MAPPING FOR PROSE RELAY

摘要

The present disclosure relates to a relay UE for relaying protocol data units between a remote UE and a radio base station. A control packet is received by the relay UE from the remote UE via a first sidelink bearer, comprising a priority indication associated with protocol data units transmitted by the remote user equipment via the first sidelink bearer. The relay UE stores an association between the priority indication and a radio bearer used by the relay UE to relay the protocol data packets. The relay UE determines, based on the stored association, the priority according to which a protocol data unit, received from the base station via the first radio bearer, should be transmitted to the remote UE, and relays the received protocol data unit to the remote user equipment using a second sidelink bearer that corresponds to the determined priority.
