Abstract

Methods and apparatuses for enhancing the reliability and performance of the PDCCH in a wireless network. The method performed by a UE comprises: receiving a configuration of search space sets for the PDCCH, each search space set comprises a number of PDCCH candidates made up of a number of resource elements; monitoring for DCIs of a specific format as indicated in the configured PDCCH candidates; wherein a configuration or an indication of an association of the search space sets with a search space set pool is provided to the UE, and at least two PDCCH candidates from the search space sets are associated with the same DCI content, or an association of two or more TCI states with a single CORESET is obtained from the network node; and applying the configuration(s) or indication of the association for receiving one or more PDCCH(s) on the search space sets.
