Abstract: A method for performing wireless communication by a first device is proposed in an embodiment. The method may comprise the steps of: configuring one or more bandwidth parts (BWPs) associated with communication with a base station; receiving first control information from a first search space for the first control information on the one or more BWPs; and receiving second control information from a second search space for the second control information on the one or more BWPs. For example, on the basis of the base station allocating, to the first device, resources associated with sidelink transmission in a carrier in which Uu communication is performed, the first search space and the second search space can overlap.

Abstract: A method for performing wireless communication by a first device and a device for supporting same are provided. The method may comprise the steps of: receiving a physical sidelink shared channel (PSSCH) from a second device; determining a physical sidelink feedback channel (PSFCH) resource associated with the PSSCH; and transmitting hybrid automatic repeat request (HARQ) feedback to the second device on the PSFCH resource. Here, the PSFCH resource can be determined on the basis of a sub channel associated with the PSSCH, a slot associated with the PSSCH, a cast type of communication between the first device and the second device, an ID of the first device, and a source ID of the second device.

Abstract: Provided herein is a method for performing, by a first apparatus, wireless communication and an apparatus for supporting the same. The method may include the steps of generating a Phase Tracking—Reference Signal (PT-RS), transmitting a Physical Sidelink Control Channel (PSCCH) to a second apparatus, mapping, based on a Cyclic Redundancy Check (CRC) on the PSCCH, the PT-RS to a subcarrier on a Physical Sidelink Shared Channel (PSSCH) resource related to the PSCCH, and transmitting the PT-RS to the second apparatus.
