Abstract: Disclosed herein is a terminal configured to receive information about one or more periodic uplink resources for transmission of HARQ-ACK information for multicast data, monitor a PDCCH in a search space for multicast configured on a specific downlink frequency resource, and detect DCI having a CRC scrambled with a G-RNTI. On a basis that the DCI indicates a specific index, and at least one of the one or more periodic uplink resources is associated with the specific index indicated by the DCI, the terminal may transmit an activation confirmation message to activate the at least one periodic uplink resource associated with the specific index.

Abstract: A method and apparatus for indicating sidelink (SL) radio link failure (RLF) in a wireless communication system is provided. A first wireless device may initialize the counter to zero upon 1) establishing the PC5-RRC connection with the second wireless device, or 2) configuring or reconfiguring the maximum number of the counter. A first wireless device may increase the counter based on no reception of any acknowledgement to the transmission of the MAC PDU. A first wireless device may indicate Sidelink (SL) Radio Link Failure (RLF) for the PC5-RRC connection based on that the counter reaches the maximum number of the counter.

Abstract: The present invention relates to a communication between MAC layer entity and PHY layer entity for parallel random access procedures of dual connectivity. In this scheme, a first PHY entity of a user equipment informs a failure of a random access preamble transmission to a first MAC entity of the UE. Then, the first MAC entity continues or stops a random access procedure without performing procedures for a random access failure.

Abstract: Disclosed are a method and device for performing uplink transmission and reception in a wireless communication system. The method by which a terminal performs an uplink transmission, according to an embodiment of the present disclosure, comprises the steps of: receiving a first downlink transmission and a second downlink transmission from a base station; and transmitting, to the base station, first HARQ-ACK information associated with the first downlink transmission and second HARQ-ACK information associated with the second downlink transmission, which have been multiplexed on a PUCCH, wherein, on the basis of the first downlink transmission being a unicast SPS downlink transmission and the second downlink transmission being a multicast downlink transmission being scheduled by first DCI, a resource for the PUCCH may be based on information related to the unicast SPS downlink transmission.
