1. A method comprising:
receiving, by a wireless device, radio resource control (RRC) messages comprising a first bitmap of frequency allocation of a search space (SS), wherein each bit of the first bitmap indicates whether frequency resources of the SS are mapped to a respective resource block (RB) set of RB sets of a bandwidth part (BWP);
monitoring, based on the first bitmap indicating that the SS is mapped to first RB sets of the RB sets, a physical downlink control channel (PDCCH) via the SS on the first RB sets;
receiving a first downlink control information (DCI) comprising a second bitmap of RB set indication, wherein each bit of the second bitmap indicates whether a respective RB set, of the RB sets, is available for downlink reception; and
monitoring, based on the first bitmap and based on the second bitmap indicating a second RB set of the first RB sets as being available for downlink reception, the PDCCH via the SS on the second RB set.
