METHOD FOR REPORTING BUFFER STATUS IN DEVICE-TO-DEVICE COMMUNICATION BASED ON CELLULAR MOBILE COMMUNICATION SYSTEM

摘要

Disclosed is a buffer status reporting method for device-to-device (D2D) communication based on a cellular mobile communication system. The buffer status reporting method according to the present invention comprises the steps of: acquiring a pair identifier designating a D2D communication pair; creating an MAC control element containing the pair identifier and buffer status information of each logical channel group of the D2D communication pair, or creating an MAC control element containing the buffer status information of each logical channel group of the D2D communication pair and another MAC control element containing the pair identifier, respectively; and transmitting the created MAC control element to a base station.
