1. A method for communicating with a second user equipment (UE) by a first UE in a wireless communication system, the method comprising:

  • generating, by a processor in the first UE, a first discovery code by converting first identification information identifying the first UE;

    generating, by the processor, a second discovery code by converting second identification information identifying the second UE;

    attaching, by the processor, first additional information to the first discovery code, wherein the first additional information is information distinguishing the first discovery code from the second discovery code;

    attaching, by the processor, second additional information to the second discovery code, wherein the second additional information is information distinguishing the second discovery code from the first discovery code;

    combining the attached first discovery code and the attached second discovery code into a single code;

    directly delivering, by the processor, the combined single code to a media access control (MAC) layer of a communication reference model in the first UE, by bypassing at least one layer of the communication reference model above the MAC layer;

    transmitting, by a transceiver of the first UE, a signal including the combined single code to the second UE; and

    identifying, by the processor, a presence of the second UE by receiving, from the second UE, the second identification information in response to the transmitted signal,wherein the first identification information comprises user account information of the first UE defined by an executing application of the processor in the first UE, andwherein the second identification information comprises user account information of the second UE defined by the executing application of the processor in the first UE.
