The present application relates to the field of wireless communication technologies, and in particular, to a PDCCH monitoring method, apparatus, electronic device and computer readable storage medium. The PDCCH monitoring method includes: determining PDCCH monitoring configuration on a target active downlink bandwidth part (BWP), after a current active downlink BWP is switched to the target active downlink BWP; performing a monitoring process on the PDCCH based on the PDCCH monitoring configuration on the target active downlink BWP. The present application achieves effective monitoring of the PDCCH on the switched active downlink BWP, saves power consumption of the UE, and ensures timely transmission of data.
