Abstract: A method and apparatus for performing a conditional cell change in a wireless communication system is provided. A wireless device receives a conditional mobility configuration associated with multiple target cells from a serving node. The conditional mobility configuration includes mobility commands for each of the multiple target cells. The wireless device receives information on one target cell among the multiple target cells from the serving node, and performs a mobility towards the one target cell based on a mobility command for the one target cell.

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: A user equipment (UE) receives, from a network, a semi-persistent scheduling (SPS) configuration and a physical uplink control channel (PUCCH) resource configuration. The PUCCH resource configuration may be included in the SPS configuration. When a change of an SPS operation is required, the user equipment transmits an SPS change request to the network and receives, from the network, an SPS resource grant activated according to the SPS change request. The user equipment changes allocation of a PUCCH resource allocated according to the PUCCH resource configuration, on the basis of the received SPS resource grant. For example, a timing at which or a period in which the PUCCH resource is allocated can be changed.

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: A method of operating a transmitting user equipment (UE) in a wireless communication system includes establishing a link with a Rx UE by the Tx UE, and transmitting an RRC message based on sidelink radio link failure (RLF) to a base station (BS) by the Tx UE. The RRC message is related to reporting of the sidelink RLF to the BS, and includes a destination identifier (ID) related to the sidelink RLF.
