Original Abstract Submitted

Systems and methods for linking Physical Downlink Control Channel (PDCCH) candidates are provided herein. In some embodiments, a method includes: receiving a configuration of a first and second Control Resource Set (CORESET) associated with a first and second Search Space (SS) set; determining that the first and second SS set are configured with a common set of parameters; activating the first and second CORESET with a first and second TCI state; linking a first PDCCH candidate in a first PDCCH monitoring occasion to a second PDCCH candidate in a second PDCCH monitoring occasion; receiving a PDCCH in the first PDCCH candidate and the PDCCH in the second PDCCH candidate; and detecting the PDCCH in the first and the second PDCCH candidates. Some embodiments might provide a simple way for linking PDCCH candidates in two SS sets to support both intra-slot and inter-slot PDCCH repetition in either TDM or FDM manner.
