Abstract: A method and apparatus for flushing a hybrid automatic repeat request (HARQ) buffer in a wireless communication system is provided. A user equipment (UE) receives information on multiple resource pools from a network, selects a first resource pool among the multiple resource pools, and stores a media access control (MAC) protocol data unit (PDU) in the HARQ buffer for transmission via the first resource pool. When the UE reselects a second resource pool among the multiple resource pools, the UE flushes the HARQ buffer.

Abstract: A method and apparatus for allocating resources for a sidelink transmission in a wireless communication system is provided. A user equipment (UE) selects a first carrier, i.e. anchor carrier, among multiple carriers, and allocates a first resource on the first carrier. The UE allocates a second resource on a second carrier, i.e. non-anchor carrier, based on an offset from the first resource on the first carrier. The UE performs the sidelink transmission by using the first resource on the first carrier and the second resource on the second carrier.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for receiving handover assistance information including a list of one or more candidate target cells; initiating a first random access procedure to a first candidate target cell of the one or more candidate target cells and a first timer for the first candidate target cell, when the first candidate target cell satisfies a handover condition; and stopping trying to connect to the first candidate target cell when any one of at least the following events occurs: (i) the first timer expires for the first candidate target cell, and (ii) a number of random access trials to the first candidate target cell reaches a maximum number.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for handling of a RRC connection request message of a remote UE by a Relay UE in wireless communication system, the method comprising: receiving NAS information for establishing RRC connection of the remote UE from a remote UE which is configured to connect to the relay UE via sidelink in state that both of the remote UE and the relay UE are in RRC idle states, transmitting a RRC connection request message with an identity of the remote UE to an eNB, when a NAS layer of the relay UE triggers only service request for the remote UE; transmitting a RRC connection setup message for the remote UE to the remote UE; and transmitting a RRC connection setup complete message with the received NAS information of the remote UE to the eNB.

Abstract: A relay user equipment (UE) can perform relay function between an eNodeB (eNB) and a remote UE by using non-3rd generation partnership project (3GPP) radio access technology (RAT). In an embodiment, the relay UE receives information on whether the data is to be forwarded to an upper layer of the relay UE or is to be forwarded to a remote UE or a network, and determines whether the data is to be forwarded to the upper layer of the relay UE or is to be forwarded to the remote UE or the network, according to the received information. In another embodiment, the relay UE, at a specific layer located below a packet data convergence protocol (PDCP) layer, receives a data unit including differentiation information for control plane data, and identifies where the data unit is destined according to the differentiation information.
