14. A method comprising:
receiving first information for a number of N>1 search space sets, wherein, for each of the N search space sets, the first information includes:
an index, wherein search space sets are indexed in an ascending order of respective indexes,
a periodicity, wherein the periodicity is same for all of the N search space sets, and
an indication that the N search space sets are linked for receptions of physical downlink control channel (PDCCH) candidates, wherein;
a PDCCH candidate is received over a number of control channel elements (CCEs) corresponding to a CCE aggregation level, and
PDCCH candidates, for search space sets from the N search space sets, with same index and with same CCE aggregation level provide identical information;
determining a number of N PDCCH reception occasions for N PDDCH candidates with same index and same CCE aggregation level, respectively, according to the first information, wherein a n-th PDCCH reception occasion from the N PDCCH reception occasions is according to a n-th search space set from the N search space sets; and
receiving N PDCCHs in the N PDCCH reception occasions.
