    Abstract: 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.

    IPC: H04W76/27

    Abstract: Disclosed are a method and an apparatus for suspending/resuming NAS signaling in a wireless communication system. Specifically, a method for a user equipment (UE) to suspend/resume non-access stratum (NAS) signaling connection in a wireless communication system comprises: a step in which when a NAS layer of the UE receives, from a radio resource control (RRC) layer, an indication that RRC connection is suspended, the UE enters an evolved packet system (EPS) mobility management (EMM)-idle mode involving a suspension indication; and a step in which when a procedure using a first NAS message is triggered, the RRC layer of the UE is requested to resume the RRC connection, wherein the request comprises a cause of RC establishment and a call type, and when the UE is in a narrow band (NB)-S1 mode, the request may further comprise data volume information of the first NAS message.

    IPC: H04W52/36 ,  H04W24/10

    Abstract: A method for a User Equipment, UE, operating in a wireless communication system, includes triggering power headroom reports (PHRs), in a first Medium Access Control (MAC), entity and a second MAC entity when a first type event occurs in the second MAC entity, wherein the UE is configured with the first MAC entity corresponding to a first base station and the second MAC entity corresponding to a second base station for a radio bearer; triggering a PHR in the second MAC entity only, when a second type event occurs in the second MAC entity, wherein the first type event includes: there are uplink resources allocated for transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold, or wherein the first type event includes: there is uplink transmission on any cell of the second MAC entity and a required power backoff for the any cell of the second MAC entity has changed more than a threshold.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling for an uplink split operation in wireless communication system, the method comprising: generating and/or receiving second data available for transmission in a PDCP entity, and determining a RLC entity to be used for submitting the second data based on first data volume, if second data volume is larger than a first threshold and less than a second threshold; indicating the second data volume to a first MAC entity associated with a primary RLC entity, if the first data volume is less than the first threshold; and indicating the second data volume to both the first MAC entity associated with the primary RLC entity and a second MAC entity associated with a secondary RLC entity, if the first data volume is larger than the second threshold.

    Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for transmitting data in a wireless communication system. According to an aspect of the present invention, the method comprising: receiving, from an enhanced Node B (eNB), a grant with an indication that indicates at least one radio bearer (RB) of which data should be transmitted using the received grant, wherein each of RBs configured to the UE is associated with a respective logical channel priority; generating a medium access control protocol data unit (MAC PDU) including data of the indicated at least one RB; and transmitting the MAC PDU using the grant.
