1. A method performed by a User Equipment (UE), the method comprising:
receiving from a network node, via a higher layer, a configuration of one or more search space sets which are associated with one or more control resource sets (CORESETs), for one or more Physical Downlink Control Channels (PDCCHs), wherein each search space set is associated with a CORESET and comprises a number of PDCCH candidates and each PDCCH candidate comprises a number of resource elements or control channel elements (CCEs) and the UE monitoring for one or more Downlink Control Information (DCIs) of a format or formats as indicated via the higher layer in the configured PDCCH candidates;
receiving from the network node, via the higher layer, a configuration or indication of an association of one or more of said search space sets with a search space set pool, wherein the higher layer configuration of a search space set comprises a parameter that comprises a value of a search space set pool ID, index, or indicator, and wherein at least two PDCCH candidates from one or more search space sets in the search space set pool that are associated with the same slot, comprise or carry a same DCI content; and
applying the configuration or indication of the association for receiving one or more PDCCHs on the one or more search space sets.
