D2D MAC PDU METHOD FOR AVOIDING TRANSMITTING MAC PDU HAVING PADDING ONLY IN A D2D COMMUNICATION SYSTEM AND DEVICE THEREFOR

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for avoiding padding only MAC PDUs in a D2D communication system. The method includes receiving a sidelink grant from a base station when the transmitting terminal is in direct communication with the receiving terminal; Confirming the size of the received side link acknowledgment; And a MAC protocol including only a Radio Link Control (RLC) header for a Medium Access Control (MAC) header and a Sidelink Traffic Channel (STCH) And transmitting an MAC PDU including at least one byte of an RLC service data unit (SDU) if the PDU is larger than a minimum size of the PDU.
