Abstract: Example embodiments of the present disclosure relate to full-duplex communications. A device determines a frequency offset between a first center frequency of a first subband and a second center frequency of a carrier.

The device also determines a target sampling rate based at least on a subcarrier spacing and the number of resource blocks in the set of resource blocks. The device further processes a signal received on the first subband based on the frequency offset and the target sampling rate. In this way, the sampling rate and the frequency offset can be adaptive to a bandwidth of the first subband, thereby improving the processing of the signal.
