Abstract: A method of performing an operation for a first user equipment (UE) in a wireless communication system includes determining a slot for transmitting a physical uplink control channel (PUCCH) based on a value related to the number of slots from a physical sidelink feedback channel (PSFCH) to the PUCCH by the first UE, and transmitting, to a base station (BS), feedback information based on the PSFCH through the PUCCH in the slot by the first UE. The value related to the number of slots is applied based on a last of slots for the PUCCH, overlapped with a slot for the PSFCH on a time axis.

Abstract: An embodiment of the present invention relates to a method for transmitting a synchronization signal in a wireless communication system. The method comprises: a step of generating a secondary synchronization signal from a combination of two sequences; and a step of transmitting the synchronization signal. The manner of combination of the two sequences varies depending on the sub-frame number to which the secondary synchronization signal is transmitted, and if the generation of the secondary synchronization signal is performed by a terminal, then the sub-frame number which determines the manner of combination is considered to be the same.

Abstract: One embodiment of a modification of a semi-persistent scheduling (SPS) operation triggered by a terminal in a wireless communication system may be a single hybrid automatic repeat request (HARQ) process according to a plurality of SPS configurations. In other words, an eNodeB (eNB) can provide, to a UE, the plurality of SPS configurations covering a variety of message sizes. Another embodiment of a modification of an SPS operation triggered by a terminal may be a negative acknowledgement (NACK) with respect to a single HARQ process according to a plurality of SPS configurations and an SPS resource grant. In other words, an eNB provides, to a UE, the plurality of SPS configurations covering a dynamic reconfiguration of a message generation period, and whenever a specific SPS resource grant is not used for transmission, the terminal can transmit the NACK with respect to the SPS resource grant.

Abstract: Disclosed are a method for transmitting and receiving data in a wireless communication system supporting vehicle-to-everything (V2X) communication, and an apparatus therefor. Specifically, a method for transmitting and receiving data by a first terminal in a wireless communication system supporting V2X comprises the steps of: receiving, from a base station, downlink control information (DCI) including resource allocation information related to the transmission of control information for a sidelink; transmitting, to a second terminal, the control information for the sidelink on the basis of the resource allocation information; and transmitting at least one type of data to the second terminal, wherein the control information for the sidelink can be transmitted in a second subframe positioned after a predetermined offset from a first subframe in which the downlink control information is received.

Abstract: Provided are an operation method in accordance with uplink semi-persistent scheduling (SPS) of a terminal in a wireless communication system and a terminal using the method. The method is characterized by: receiving, from a base station, downlink control information (DCI) for indicating activation or release of uplink SPS; and decoding the DCI on the basis of a first radio network temporary identifier (RNTI) or a second RNTI. If the DCI is a first DCI for SPS for transmitting a signal to the base station, the DCI is decoded on the basis of the first RNTI, and, if the DCI is a second DCI for SPS for transmitting a vehicle-to-everything (V2X) signal, the DCI is decoded on the basis of the second RNTI. And the first RNTI and second RNTI are RNTIs that are different from each other.

Abstract: Provided is a method for a relay that supports a time division duplex (TDD) operation for temporally multiplexing a first link, which is either an uplink or downlink, and a second link, which is different from the first link. The method comprises: receiving, by the relay, a first radio signal through a first reception antenna for the first link; limiting, by the relay, an amplification rate of a first transmission antenna for the first link or an amplification rate of a second transmission antenna for the second link, based on an amplitude of the first radio signal; and relaying, by the relay, the first radio signal through the first transmission antenna without decoding the first radio signal if the amplification rate of the second transmission antenna is limited.
