Abstract: The present application provides a method for transmitting or receiving a sidelink signal by a terminal in a wireless communication system. Specifically, the method for transmitting or receiving a sidelink signal comprises the steps of: transmitting a first sidelink signal during a transmission period by using a transmission resource selected among resource units included in a first transmission resource pool; monitoring resource units included in a second transmission resource pool; and transmitting a second sidelink signal during the transmission period by using a selected transmission resource on the basis of a result of the monitoring among the resource units included in the second transmission resource pool when a resource pool changes from the first transmission resource pool to the second transmission resource pool, wherein the second transmission resource pool is included in a reception resource pool corresponding to the first transmission resource pool.

Abstract: A method of operating a Tx user equipment (UE) in a wireless communication system includes transmitting a random access preamble corresponding to a synchronization signal block (SSB) by the Tx UE, receiving a random access response in response to the random access preamble by the Tx UE, establishing a link with a Rx UE by the Tx UE, and transmitting a radio resource control (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.

Abstract: A method for receiving a feedback signal of a base station in a wireless communication system comprises the steps of: transmitting a data packet to a terminal; monitoring, during a preset monitoring interval, a first feedback signal representing whether the data packet has been successfully received or not; determining whether the first feedback signal monitored during the preset monitoring interval is an ACK signal or a NACK signal; and retransmitting the data packet to the terminal when the first feedback signal is determined to be the NACK signal. A first monitoring interval for monitoring the first feedback signal in order to determine the NACK signal may be set to be different from a second monitoring interval for monitoring the first feedback signal in order to determine the ACK signal.

Abstract: The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for performing sidelink transmission prioritized over the uplink transmission in wireless communication system, the method comprising: generating uplink data and sidelink data to be transmitted in a subframe; determining that uplink transmission is denied in the subframe if sidelink transmission is prioritized over the uplink transmission; and transmitting the sidelink data in the subframe where the uplink transmission is denied, wherein the subframe is one of subframes allowed for denial of the uplink transmission during a validity period.

Abstract: An embodiment of the present invention provides a method for a first UE to transmit a physical sidelink shared channel (PSSCH) in a wireless communication system, the PSSCH transmission method comprising: a step of excluding subframes, used by a second UE, from candidate subframes for PSSCH transmission; and a step of selecting a subframe for transmitting a PSSCH and transmitting the PSSCH, after excluding the subframes, used by the second UE, from the candidate subframes, wherein the subframes used by the second UE include subframes assumed to be repeatedly used by the second UE according to a reservation period of the second UE, wherein, if the reservation period of the second UE is smaller in value than a predetermined value, the shorter the reservation period of the second UE becomes, the greater the number of the subframes assumed to be repeatedly used becomes.

Abstract: Disclosed in the present application is a method for receiving by a terminal a multicast signal in a wireless communication system. Specifically, the method comprises the steps of: attempting to receive, from a network, a control signal for scheduling a multicast signal; receiving the multicast signal from the network and performing decoding on the basis of the control signal; and transmitting a data negative acknowledgement signal to the network when the decoding of the multicast signal fails, wherein a control negative acknowledgement signal is transmitted to the network when the reception of the control signal has failed.
