Abstract: Provided is a method for transmitting a signal by means of a sidelink terminal in a wireless communication system, according to an embodiment of the present invention. The method for transmitting a signal comprises the steps of: selecting any one of an eNB and a gNB as a synchronization reference; and transmitting a sidelink channel/signal including an SSB (SS/PBCH block) on the basis of synchronization of the base station selected as the synchronization reference, wherein when dual connectivity (DC) is configured for the terminal, the terminal selects a master NB (NodeB) among the eNB as the synchronization reference. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

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: The present disclosure provides a method for transmitting and receiving a sidelink synchronization signal (SLSS) in a wireless communication system. In detail, the method performed by a first terminal includes receiving configuration information related to the SLSS; receiving the SLSS from a second terminal; determining whether the received SLSS is an SLSS related to sidelink communication or an SLSS related to sidelink discovery based on the received configuration information; and transmitting the received SLSS when the received SLSS is the SLSS related to sidelink discovery. Through this, the method proposed in the present disclosure has the effect of reducing unnecessary battery consumption of the first terminal and minimizing interference in the terminals of the neighboring cell.
