    Abstract: Disclosed are a method and apparatus for performing uplink transmission in a wireless communication system. The method by which a terminal performs uplink transmission, according to an embodiment of the present disclosure, comprises the steps of: receiving, from a base station, configuration information related to at least one serving cell; receiving a unicast physical downlink shared channel (PDSCH) or a multicast PDSCH from the base station in a first serving cell of a secondary physical uplink control channel (PUCCH) group from among the at least one serving cell; and transmitting, to the base station, hybrid automatic repeat request (HARQ)-acknowledgement (ACK) information regarding the unicast PD SCH or the first multicast PDSCH, wherein on the basis that the multicast PDSCH is received from the base station in the first serving cell, the HARQ-ACK information may be transmitted to the base station by using a PUCCH resource of a second serving cell of a primary PUCCH group from among the at least one serving cell.

    Abstract: A method and apparatus for Sidelink (SL) Discontinuous Reception (DRX) operation based on resource allocation is provided. A first wireless device, e.g., receiving user equipment (RX UE), monitors first Physical Sidelink Control Channel (PSCCH) transmissions from a second wireless device, e.g., transmitting UE (TX UE), in a Sidelink (SL) active time for SL Discontinuous Reception (DRX). The first wireless device receives, from the second wireless device, an indication to reselection of sidelink resources, and adjusts the SL active time based on the indication. The first wireless device monitors second PSCCH transmissions from the second wireless device in the adjusted SL active time.

    Abstract: A method and apparatus for periodic transmissions for a configured grant is provided. A first device operating in a wireless communication system transmits, to a second device, a media access control (MAC) protocol data unit (PDU) by using a first resource of a configured grant (CG) in a first period for which the first resource of the CG is associated with a HARQ process identifier (ID), and flushes a HARQ buffer associated with the HARQ process ID in a second period for which a second resource of the CG is associated with the HARQ process ID. Then, the first device ignores a retransmission resource associated with the HARQ process ID based on flushing the HARQ buffer.

    Abstract: The present disclosure relates to method and apparatus for performing mobility in wireless communication system. According to an embodiment of the present disclosure, a method performed by a wireless device in a wireless communication system comprises: receiving a first message comprising handover commands of candidate target cells, each of the handover commands being related to an index; receiving a second message comprising the index related to a first handover command of a candidate target cell among the handover commands, and a second handover command of the candidate target cell; updating the first handover command based on the second handover command; identifying that the candidate target cell satisfies a handover condition for the candidate target cell based on a measurement result for the candidate target cell; and performing a handover to the candidate target cell satisfying the handover condition based on the updated first handover command.

    Abstract: A method and apparatus for reconfiguration of sidelink configuration and sidelink resource allocation in a wireless communication system is provided. Upon leaving a connected state and entering a new state, while in the new state, a first wireless device configured to operate in a wireless communication system keeps performing sidelink transmission to a second wireless device based on a first sidelink configuration received via dedicated signaling, receives, from a network via broadcast signaling, a second sidelink configuration, and performs the sidelink transmission to the second wireless device based on the second sidelink configuration.

    Abstract: Disclosed are a method and apparatus for performing a random access procedure in a wireless communication system. The method for performing a random access procedure according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, configuration information related to random access, wherein the configuration information includes a scaling factor for a back-off indicator (BI) for a specific type of terminal; transmitting a first random access preamble to the base station; receiving, from the base station, a random access response (RAR) in response to the first random access preamble, wherein the RAR includes the BI; and on the basis of the RAR not including a random access preamble identifier (RAPID) associated with the first random access preamble, transmitting a second random access preamble to the base station.
