Abstract: A method for a wireless device operating in a wireless communication system includes receiving configuration information for configuring a non-Physical Uplink Control Channel (PUCCH) cell; and transmitting a Hybrid Automatic Repeat request (HARQ) feedback of the non-PUCCH cell on a special cell (SpCell) or a PUCCH cell other than SpCell, according to indication information. Further, when the indication information is not received with the configuration information, the HARQ feedback is transmitted on the SpCell, and when the indication information is received with the configuration information, the HARQ feedback is transmitted on the PUCCH cell.

Abstract: In a wireless communication system, a user equipment (UE) may reselect a sidelink resource to be used for vehicle-to-everything (V2X) communication. The reselection of sidelink resource may be triggered by various conditions. In particular, the reselection of the sidelink resources may be triggered when a value of sidelink resource reselection counter is zero. More specifically, the UE determines that data for the V2X communication is available in a sidelink traffic channel (STCH), determines that a value of the sidelink resource reselection counter is zero, and reselects the sidelink resources.

Abstract: A method and apparatus for a user equipment (UE) performing random access to a network is disclosed. For this end, the UE determines a predetermined number of beams, as candidate beams for the random access to the network, among multiple beams, wherein each of the multiple beams is allocated on different time domain units. And, the UE transmits the random access preamble over a transmission beam selected as one from the candidate beams to the network.

Abstract: Provided is a method for performing a random access procedure by a terminal in a wireless communication system. The method comprises the steps of: selecting a first beam group including a configured number (M) of beams; transmitting a random access preamble to a base station via the first beam group; adjusting a value of M when it is determined that the random access procedure has failed; and reselecting a second beam group including the adjusted number of M beams.

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.

Abstract: A transmitting device generates a medium access control (MAC) protocol data unit (PDU), and transmits the MAC PDU. The transmitting device generates the MAC PDU such that the MAC PDU includes at least a MAC service data unit (SDU) and a first MAC subheader of the MAC SDU which is attached immediately after the end of the MAC SDU, or a MAC control element (CE) and a second MAC subheader of the MAC CE which is attached immediately after the end of the MAC CE.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for triggering a buffer status reporting in dual connectivity, the method comprising: configuring a threshold value for a PDCP entity associated with a first MAC entity for a first eNB and a second MAC entity for a second eNB for a radio bearer; checking, by the PDCP entity, whether an amount of uplink data available for transmission in the PDCP entity is less than the threshold value; and indicating, by the PDCP entity, that the amount of uplink data available for transmission in the PDCP entity is ‘0’ to the second MAC entity, if the amount of uplink data available for transmission in the PDCP entity is less than the threshold value.
