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: A method and apparatus for a sidelink of a wireless communication system are proposed. A transmission UE can contiguously or non-contiguously allocate radio resources through sidelink communication. A specific resource allocation method is selected in consideration of latency of sidelink data/packets or other factors. For example, a specific resource allocation method can be determined based on whether a plurality of contiguous subchannels is allocated to radio resources before a first time, which is determined based on latency of data/packets.
