D2D -2 METHOD FOR TRANSMITTING AN EXPLICIT SIGNAL OF LAYER-2 STATE VARIABLES FOR D2D COMMUCATION SYSTEM AND DEVICE THEREFOR

摘要

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and apparatus for transmitting an explicit signal of a Layer-2 state variable for a D2D communication system, the method comprising: Generating a configuration message including an initial value of an RLC state variable used for an RLC (Radio Link Control) entity; Transmitting the configuration message to the second terminal; And transmitting an RLC PDU to a receiving RLC entity of the second terminal in consideration of the initial value, wherein the configuration message includes transmission using the initial value before transmission of the RLC PDU.
