Abstract

A method by a user equipment (UE) is described. The method includes receiving, 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 of a search space set, receiving a second RRC parameter with a second information element structure to define how and where to search for PDCCH candidates of a search space set, and a search space set corresponds to two types of search space set, wherein the first information element structure is capable of indicating of which one of the two types the search space set is, the second information element structure is only capable of indicating one fixed type.

Claims7

Dependent claims

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.
