Abstract: Suggested is a novel condition for a media access control (MAC) entity in user equipment (UE) reselecting a sidelink resource in a wireless communication system. The MAC entity of the UE can reselect a sidelink resource when a configured sidelink grant does not satisfy a latency requirement according to ProSe per-packet priority (PPPP). More particularly, configuration is performed by an upper layer so that the MAC entity transmits on the basis of sensing using a resource pool; the MAC entity selects generation of a configured sidelink grant corresponding to transmission of a plurality of MAC protocol data units (PDU); and when data is available in a sidelink traffic channel (STCH) and the configured sidelink grant does not satisfy the latency requirement according to the PPPP, a sidelink resource is reselected.

Abstract: In the performance of a proximity-based services (ProSe) user equipment (UE)-to-network relay operation, when a remote UE needs to transmit control/user plane data to a network, a relay UE may be in a radio resource control (RRC) idle state. At this time, the relay UE receives an RRC connection establishment cause from the remote UE, and performs an RRC connection establishment procedure for the ProSe UE-to-network relay of the remote UE on the basis of the received RRC connection establishment cause.

Abstract: A light connection state is different from a substate of a radio resource control connection (RRC) state or the RRC connection state, and is a state which allows free movement of a UE in a plurality of cells without involving a handover process controlled by a network. A terminal in the RRC connection state, which has received a cell radio network temporary identity (C-RNTI) from a first cell, enters the light connection state and then moves to a second cell. The terminal in the light connection state receives, from the second cell, a random access reply including a temporary C-RNTI during a random access process, and replaces the C-RNTI received from the first cell with the temporary C-RNTI.
