Title:
PHYSICAL DOWNLINK CONTROL CHANNEL (PDCCH) MONITORING WITH OVERLAPPING RESOURCES
Document Type and Number:
WIPO Patent Application WO/2019/139716
Kind Code:
A1
Abstract:
Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.
