Title:
METHOD AND APPARATUS FOR DETECTING PHYSICAL DOWNLINK CONTROL CHANNEL
Document Type and Number:
WIPO Patent Application WO/2021/088783
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and an apparatus for detecting a physical downlink control channel, relating to the technical field of communications. The method for detecting a physical downlink control channel is used in a terminal, and comprises: acquiring at least two search space sets and switching conditions, the at least two search space sets comprising a first search space set and a second search space set; and switching between the first search space set and the second search space set according to the switching conditions to implement PDCCH detection. The technical solution of the present invention can implement switching of a terminal between different search space sets.
