1. A physical downlink control channel (PDCCH) monitoring method by a user equipment (UE), the PDCCH monitoring method comprising:
receiving higher layer signaling including PDCCH monitoring configuration information for a target active downlink bandwidth part (BWP) on a current active downlink BWP, wherein the PDCCH monitoring configuration information indicates a relationship between a PDCCH monitoring configuration for the current active downlink BWP and a PDCCH monitoring configuration for the target active downlink BWP;
determining the PDCCH monitoring configuration for the target active downlink BWP, based on the relationship, after the current active downlink BWP is switched to the target active downlink BWP; and
performing a monitoring process on a PDCCH based on the PDCCH monitoring configuration for the target active downlink BWP,
wherein the PDCCH monitoring configuration for the target active downlink BWP comprises at least one of:
a periodicity of PDCCH monitoring;
a number of times to perform the PDCCH monitoring; or
an aggregation level (AL) of a control channel element (CCE) of the PDCCH monitoring.
