Abstract: A method and apparatus for measurement reporting during a conditional PCell handover in a wireless communication system is provided. A wireless device receives, from the source cell, a handover command including a handover condition for a target cell. A wireless device performs measurement on at least one of neighbor cells. A wireless device transmits, to the target cell, a handover complete message based on that the handover condition for the target cell is met, wherein the handover complete message includes results of the measurement on the at least one of the neighbor cells.

Abstract: A method and apparatus for discarding data among associated transmission buffers in a wireless communication system is provided. A wireless device generates a first data packet and a second data packet, and performs a random access (RA) procedure based on the first data packet. When the RA procedure based on the first data packet fails, the wireless device discards the first data packet, and continues the RA procedure based on the second data packet. A media access control (MAC) layer indicates a radio resource control (RRC) layer that the RA procedure based on the second data packet is performed.

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 LCP procedure by a Relay UE in wireless communication system, the method comprising: performing, by the relay UE, a LCP procedure for generating MAC PDU by considering a priority of a first logical channel of a remote UE and a priority of a second logical channel of the relay UE; and transmitting the MAC PDU to a network, wherein if the priority of the second logical channel is equal to the priority of the first logical channel, data from the second logical channel of the relay UE is prioritized over data from the first logical channel of the remote UE during the LCP procedure.
