A wireless device receives configuration parameters indicating: a control resource set (coreset) configured with a first transmission configuration indicator (TCI) state and a second TCI state; and a bitmap comprising a plurality of bits. Each bit of the plurality of bits indicates one of the first TCI state or the second TCI state and is for a respective repetition of repetitions of a downlink control information (DCI). The wireless device receive, via a search space associated with the coreset, each of a plurality of repetitions of a first DCI using an associated TCI state indicated by a respective bit of the plurality of bits.

The present application relates to a user equipment, a base station, and a method for PDCCH repetition. The base station transmits a MIB corresponding to a SSB to the user equipment. The MIB includes a configuration of search space zero. The user equipment receives the MIB corresponding to the SSB from the base station. The user equipment determines that the configuration of search space zero indicates a PDCCH repetition.
