Method and apparatus for relaying using non-3gpp radio access technology in wireless communication system

Abstract

A relay user equipment (UE) can perform relay function between an eNodeB (eNB) and a remote UE by using non-3rd generation partnership project (3GPP) radio access technology (RAT). In an embodiment, the relay UE receives information on whether the data is to be forwarded to an upper layer of the relay UE or is to be forwarded to a remote UE or a network, and determines whether the data is to be forwarded to the upper layer of the relay UE or is to be forwarded to the remote UE or the network, according to the received information. In another embodiment, the relay UE, at a specific layer located below a packet data convergence protocol (PDCP) layer, receives a data unit including differentiation information for control plane data, and identifies where the data unit is destined according to the differentiation information.
