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.

Abstract
A method and an apparatus for direct communication between User Equipments (UEs) in a wireless communication system are provided. A method for communicating with a second UE by a first UE in the wireless communication system includes generating a discovery code used for communicating with the second UE, and transmitting the generated discovery code to one middle layer among a plurality of layers.

8. An apparatus for communicating with a second user equipment (UE) by a first UE in a wireless communication system, the apparatus comprising:
-
a processor configured to; generate a first discovery code by converting first identification information identifying the first UE, generate a second discovery code by converting second identification information identifying the second UE, attach 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, attach 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, combine the attached first discovery code and the attached second discovery code into a single code, and directly deliver 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; and a transceiver configured to transmit a signal including the combined single code to the second UE, wherein the processor is further configured to identify 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, and wherein the second identification information comprises user account information of the second UE defined by the executing application of the processor in the first UE. - View Dependent Claims (9, 10, 11, 12, 13)
