1. A method of wireless communication performed by a first user equipment (UE), comprising:
receiving, from a second UE and using a first fast Fourier transform (FFT) window configuration, a physical sidelink control channel (PSCCH) signal associated with a physical sidelink shared channel (PSSCH) signal, the first FFT window configuration associated with at least one of a first symbol boundary adjustment, a first symbol boundary shift, a first FFT window timing, or a first FFT window location;
identifying, based at least in part on the reception of the PSCCH signal, one or more values of one or more parameters estimated from the PSCCH signal;
selecting, based at least in part on the one or more values of the one or more parameters, a second FFT window configuration to be used to receive the PSSCH signal, the second FFT window configuration associated with at least one of a second symbol boundary adjustment, a second symbol boundary shift, a second FFT window timing, or a second FFT window location; and
receiving, from the second UE, the PSSCH signal using the second FFT window configuration.
