1. A user equipment (UE), comprising:
a receiver configured to receive, from a base station, a first radio resource control (RRC) parameter with a first information element structure to define how and where to search for PDCCH candidates for a first search space set and a second RRC parameter with a second information element structure to define how and where to search for PDCCH candidates for a second search space set, wherein
each of the first search space set and the second search space set corresponds to either of a first type of search space set and a second type of search space set,
the first information element structure includes a third RRC parameter capable of designating which one of the two types the first search space set is, and
the second information element structure includes a fourth RRC parameter capable of designating the first type of search space set but not capable of designating the second type of search space set,
the receiver is configured to monitor, in the first search space set, PDCCH candidates for DCI formats indicated based on the first RRC parameter, and
the receiver is configured to monitor, in the second search space set, PDCCH candidates for DCI formats indicated based on the second RRC parameter.
