METHOD FOR TRIGGERING A BSR FOR SIDELINK DATA IN A D2D COMMUNICATION 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 a device for triggering a BSR for sidelink data in a D2D communication system, the method comprising: configuring a sidelink logical channel; receiving a sidelink data of the sidelink logical channel from upper layer; checking whether the sidelink data of the sidelink logical channel is received from the eNB or not; and triggering a buffer status reporting according to a result of the checking, wherein if the sidelink data of the sidelink logical channel is received from the eNB, the buffer status reporting is not triggered.
