Abstract: Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: obtaining configuration information including at least one of information related to a fixed frame period (FFP) and information related to an FFP offset; and monitoring a physical sidelink control channel (PSCCH) or a physical sidelink shared channel (PSSCH) from a second device during a first time within a first FFP determined by the configuration information, wherein the PSCCH is a channel carrying first sidelink control information (SCI) for scheduling of the PSSCH and second SCI, wherein the PSSCH is a channel carrying the second SCI and data, and wherein, based on a failure to monitor the PSCCH from the second device during the first time within the first FFP, the monitoring of the PSCCH from the second device is skipped during a second time outside the first time within the first FFP.
