Abstract: This disclosure provides a physical downlink control channel (PDCCH) monitoring control method and a related device. The method includes, in the event that an active bandwidth part (BWP) of a terminal has changed from a first BWP to a second BWP, determining whether to perform PDCCH monitoring during a target discontinuous reception onduration (DRX-onduration), where when a BWP switching time point for the terminal is outside an onduration, the target DRX-onduration is an onduration next to the BWP switching time point; and when the BWP switching time point for the terminal is within the onduration, the target DRX-onduration is an onduration within which the BWP switching time point falls.
