    摘要: A communications device acting as a relay device is configured to communicate with a transmitting node and a receiving node. The communications device acting as the relay is configured to receive signals representing protocol data units formed from one or more service data units via a first wireless access interface from the transmitting node according to a first automatic repeat request process for transmission to the receiving node, transmit signals representing the received protocol data units via a second wireless access interface to the receiving node according to a second automatic repeat request process, and store the protocol data units received by the receiver circuitry for transmission to the receiving node according to the second automatic repeat request process.

    摘要: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing a buffer status reporting in a D2D communication system, the method comprising: configuring a plurality of sidelink logical channels, wherein each of the plurality of sidelink logical channels has an associated priority and belongs to a LCG, and one or more of LCGs belong to a ProSe Destination; generating a SL BSR MAC CE including buffer sizes of LCGs in decreasing order of a LCG priority, wherein the LCG priority of a LCG is determined as a highest priority of a logical channel among priorities of logical channels belonging to the LCG; and transmitting a MAC PDU including the SL BSR MAC CE.
