Abstract: Proposed is a method for performing wireless communication by a first device. The method may comprise a step of receiving a channel state information reference signal (CSI-RS) through a physical sidelink shared channel (PSSCH) from a second device, measuring a channel state through the CSI-RS on the basis of a reference type associated with the PSSCH, and transmitting information about the channel state to the second device. For example, the reference type associated with the PSSCH may be determined on the basis of whether a slot including a resource associated with the PSSCH includes a resource associated with a physical sidelink feedback channel (PSFCH).
