    Abstract: The present invention relates to a method and a device for transmitting a queuing delay measurement report in a wireless communication system, the method comprising: receiving a queuing delay measurement configuration including discard timer values and a measurement period from an eNB, wherein each of the discard timer values respectively corresponds to one radio bearer among a set of radio bearers associated with a QCI configured for the UE, determining a queuing delay for the QCI based on queuing delays for PDCP SDUs from the set of radio bearers during the measurement period, selecting a specific discard timer value among the discard timer values, calculating a queuing delay ratio for the QCI by dividing the queuing delay for the QCI by the specific discard timer value, and transmitting a queuing delay measurement report including the QCI and the queuing delay ratio for the QCI to the eNB.

    Abstract: A method and apparatus for a user equipment (UE) performing a random access to a network are disclosed. For this end, the UE selects a first carrier for the random access among multiple carriers, and transmits a first random access preamble for a first random access procedure via the first carrier to the network. Then, the UE applies backoff time to the first carrier and reselects a second carrier for the first random access procedure among the multiple carriers, when the first random access procedure is determined as not successful; and transmits a second random access preamble via the second carrier to the network. Here, reselecting the second carrier is performed before the backoff time applied to the first carrier ends.

    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.
