1. A user equipment (UE), comprising:
a receiver configured to receive a first physical downlink control channel (PDCCH) that provides a first downlink control information (DCI) format, wherein:
the first DCI format indicates a first configuration for reception of second PDCCHs, and
a PDCCH from the second PDCCHs provides a second DCI format; and
a processor, operably connected to the receiver, the processor configured to determine:
parameters for reception of the second PDCCHs based on the first configuration after the reception of the first DCI format, and
parameters for reception of the second PDCCHs based on a second configuration before the reception of the first DCI format.
