Abstract: One embodiment relates to a method for a first terminal to transmit a sidelink signal in a wireless communication system, the method comprising: a step in which the first terminal determines at least one from among transmission parameters, a CSI-RS transmission configuration, and a DMRS configuration; and a step in which the first terminal transmits the sidelink signal to a second terminal, on the basis of at least one from among the transmission parameters, CSI-RS transmission configuration, and DMRS configuration. The terminal determines, on the basis of establishment of a unicast connection with the second terminal, a first value corresponding to a relative difference from the second terminal by using information included in a message from the second terminal and sensor information, and determines at least one from among the transmission parameters, CSI-RS transmission configuration, and DMRS configuration on the basis of the first value.

Abstract: In a wireless communication system, a third party different from both terminals or a base station, which are parties to vehicle-to-everything (V2X) communication, may be involved in resource allocation for the V2X communication. For example, a first terminal performing V2X communication with a second terminal receives recommendation information recommending a resource available for the V2X communication from a third terminal and performs the V2X communication with the second terminal by using a recommended resource determined based on the recommendation information or a resource selected by the first terminal based on the recommendation information.

Abstract: One embodiment of the present invention relates to a method for receiving a sidelink synchronization signal (SLSS) by a terminal in a wireless communication system, comprising the steps of: receiving a physical sidelink broadcast channel (PSBCH); determining which of global navigation satellite systems (GNSS) or an eNB is to be a synchronization source according to priority information included in the PSBCH; and receiving an SLSS associated with the determined synchronization source, wherein the terminal determines that the priority information is valid only when a public land mobile network (PLMN) associated with the priority information matches a PLMN to which the terminal belongs.

Abstract: An embodiment of the present disclosure proposes a method for a first user equipment (UE) to measure a channel occupancy ratio (CR) in a wireless communication system, the method including: a step in which the first UE transmits a signal to a second UE; and a step in which the first UE measures the CR on the basis of the amount of resources for signal transmission, wherein the CR is measured by using at least any one among a scaling value and a bias value which are set on the basis of a comparison result between the transmission power for transmitting the signal and a threshold. 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.
