1. A method for determining a relay master in a wireless communication system including a plurality of user equipments (UEs) and the base station, the method comprising:
- communicating with the plurality of UEs;
determining the relay master from the plurality of UEs based on information on the plurality of UEs;
notifying a UE determined as the relay master that the UE is determined as the relay master; and
communicating with a relay slave by way of the relay master, the relay master being another UE that is not the relay master among the plurality of UEs.
