1. A method for transmitting discovery information by a user equipment (UE) in a wireless communication system supporting a proximity service, the method comprising:

  • receiving directly from a proximity service (ProSe) protocol layer of the UE, in a medium access control (MAC) layer of the UE, discovery information for discovery associated with the proximity service;

    generating, in the MAC layer, a MAC protocol data unit (PDU) including the received discovery information;

    transmitting, in a physical (PHY) layer, a discovery signal including the generated MAC PDU, andtransmitting or receiving between the UE and a base station,wherein transmission or reception between the UE and the base station is higher in priority than transmission of the discovery signal.
