1. A method for monitoring a physical downlink control channel (PDCCH), comprising:
monitoring, by a terminal device, the PDCCH according to first configuration information, wherein the first configuration information is used for indicating a first PDCCH search space for monitoring the PDCCH; and
performing, by the terminal device, extra PDCCH monitoring according to second configuration information after a first monitoring time point if downlink control information (DCI) is detected by the terminal device at the first monitoring time point in the first PDCCH search space; wherein the second configuration information is used for indicating a second PDCCH search space for performing the extra PDCCH monitoring; wherein the method further comprises:
receiving, by the terminal device, radio resource control (RRC) signaling, a medium access control control element (MAC CE) or a broadcast message, carrying the second configuration information.
