    摘要: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for configuring an activated SCell with PUCCH resource in a carrier aggregation system, the method comprising: configuring with a Secondary Cell (SCell); receiving a Radio Resource Control (RRC) signaling indicating that Physical Uplink Control Channel (PUCCH) resource is configured for the SCell; configuring the PUCCH resource with the SCell according to the RRC signaling; and disabling a SCell deactivation timer associated with the SCell if the SCell deactivation timer associated with the SCell is running when the RRC signaling is received.

    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.

    摘要: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for releasing a sidelink radio bearer for D2D communication system, the method comprising: determining, by the UE, whether a peer UE releases a sidelink radio bearer or not, wherein the UE transmits data to a peer UE over the sidelink radio bearer; generating, by the UE, a release request for the sidelink radio bearer identified by a targetID, a sourceID, and a LCID, when the UE determines the peer UE releases the sidelink radio bearer; and transmitting, to the peer UE, the release request for the sidelink radio bearer with the targetID, the sourceID, and the LCID associated with the sidelink radio bearer to be released.

    摘要: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting a sidelink data in a D2D communication system, the method comprising: configuring to communicate with at least one destination; receiving a sidelink data corresponding to a destination of the at least one destination from an eNB; receiving a sidelink grant MAC CE including at least one sidelink grant and at least one destination identifier associated with a corresponding sidelink grant from the eNB; and transmitting the sidelink data to the destination by using a sidelink grant associated with the destination in the sidelink grant MAC CE if there is the sidelink grant associated with the destination in the sidelink grant MAC CE.
