Disclosed herein are an operating method of a first terminal in a wireless communication system and a device for supporting the method. According to an embodiment applicable to the present disclosure, the method may include performing, by the first terminal, a beam alignment with a second terminal and receiving, by the first terminal, downlink control information (DCI) associated with the second terminal from a base station. Herein, the DCI may be decoded based on at least one of a common radio network temporary identifier (RNTI), a sidelink-RNTI (SL-RNTI) of the second terminal, and a sidelink connection specific ID. In addition, the method may further include receiving, by the first terminal, a physical sidelink control channel (PSCCH) and a physical sidelink shared channel (PSSCH) from the second terminal based on the DCI.

An embodiment of the present disclosure provides a method for performing sidelink communication by a first device. The method may comprise the steps of: reserving a first reservation resource on the basis of a first sensing operation within a sensing window; on the basis of a second sensing operation within the sensing window, reserving a second reservation resource partially overlapping with the first reservation resource; obtaining a first RSRP value of the first reservation resource; obtaining a second RSRP value of the second reservation resource; deriving a sum value on the basis of the first RSRP value and the second RSRP value; and on the basis that the sum value exceeds a first threshold value, excluding the first reservation resource and the second reservation resource from available resources for sidelink communication of the first device.
