    Abstract: The present disclosure relates to a positioning method using a sidelink, and a device. According to one aspect, a method of performing positioning through a sidelink by a vehicle terminal can comprise the steps of: receiving a request positioning reference signal (PRS) from a positioning terminal; determining the positioning terminal-based direction angle on the basis of the request PRS; determining a response PRS ID corresponding to the request PRS ID of a request RRS, on the basis of the determined direction angle; and transmitting a response PRS corresponding to the determined response PRS ID. The vehicle terminal is capable of communicating with at least one of another vehicle terminal, a UE related to an autonomous driving vehicle, the BS or a network.

    Abstract: A method for performing wireless communication by a first device includes: receiving information related to a time division duplex (TDD) slot configuration, transmitting, to a second device, a sidelink-synchronization signal block (S-SSB), the S-SSB including a sidelink primary synchronization signal, a sidelink secondary synchronization signal, and a physical sidelink broadcast channel, and transmitting, to the second device, a physical sidelink shared channel based on the information related to the TDD slot configuration. Candidate resources to which a bitmap related to a sidelink resource pool is applied (i) are configured based on the information related to the TDD slot configuration and (ii) include one or more slots. Configuration information related to a sidelink symbol included in each of the one or more slots is received, the configuration information including information related to a position of the sidelink symbol configured to be the same for the candidate resources.
