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