TECHNIQUES FOR PDCCH MONITORING AGGREGATION

Abstract:

Wireless communications systems and methods related to a downlink search space with or without PDCCH monitoring aggregation in a wireless communication network are provided. A UE receives a monitoring configuration from a BS including a repetition of DCI over a plurality of PDCCH monitoring occasions of a search space. The monitoring configuration indicates one or more forms of diversity between PDCCH monitoring occasions. Diversity may be achieved, for example, by a CORESET frequency allocation difference, a PDCCH monitoring occasion frequency resource allocation difference, and/or different hashing functions for the CCE index of PDCCH monitoring occasions within a CORESET. Additional diversity is possible by using different beams and other methods. When activated either explicitly or implicitly, UE monitors for PDCCH transmissions from the first device utilizing the configured PDCCH monitoring aggregation.
