Method and apparatus for supporting radio bearer configuration for UE-to-network relay

A method and apparatus for supporting radio bearer configuration for user equipment (UE)-to-network relay is disclosed. In one embodiment, a relay user equipment establishes a PC5 radio resource control connection with a remote user equipment. The relay user equipment also transmits a radio resource control message to the network node to request the radio bearer configuration to support the user equipment-to-network relay. Further, the relay user equipment receives a radio resource control reconfiguration message from the network node, where the radio resource control reconfiguration message includes a Uu configuration for a Uu radio link control bearer associated with the signaling radio bearer. In addition, the relay user equipment receives a radio resource control reconfiguration completion message from the remote user equipment. The relay user equipment also transmits a radio resource control reconfiguration complete message to the network node on the Uu radio link control bearer. 本发明公开一种用于支持用户设备(UE)到网络中继
