Title:
METHOD FOR TRANSMITTING AND RECEIVING DOWNLINK CONTROL CHANNEL, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/080511
Kind Code:
A1
Abstract:
The present disclosure discloses a method by which a terminal receives a physical downlink control channel (PDCCH) in a wireless communication system. In particular, the method may comprise: receiving, through an upper layer, first information related to search space set group (SSSG) switching and second information related to PDCCH monitoring skipping; receiving downlink control information (DCI) indicating a PDCCH monitoring skipping operation through a search space set; determining a duration of the PDCCH monitoring skipping operation on the basis of the DCI and an SSSG corresponding to the search space set; and receiving the PDCCH after the duration ends.
