wherein the first relay capability information, which indicates a capability of the UE to act as a Proximity-based Services (ProSe) UE to network relay, is transmitted in a Non-Access Stratum (NAS) message.
12. The method according to claim 11 , wherein the UE capability information includes second relay capability information which indicates relay capability between the UE and another UE.
13. The method according to claim 12 , further comprising:
controlling the transceiver to transmit the second capability information in a NAS message.
14. The method according to claim 11 , further comprising:
transmitting the UE capability information to a Mobile Management Entity (MME) from the base station.
15. The method according to claim 11 , further comprising:
controlling the transceiver to transmit the UE capability information in an attach request message or in a Tracking Area Update Request message.
16. A method for a base station, including a transceiver and a controller, used in a wireless communication system, the method comprising:
controlling the transceiver to receive, from a user equipment (UE), UE capability information regarding capability of the UE;
