1. A network node configured to communicate with a wireless device (WD), the network node comprising:
processing circuitry configured to:
determine a sparse search space (SS) configuration of the WD to monitor a physical downlink control channel (PDCCH) in a sparse SS in a first bandwidth part (BWP);
determine a dense SS configuration of the WD to monitor the PDCCH in a dense SS in a second BWP; and
select one of the determined sparse SS configuration and the determined dense SS configuration; and
a radio interface in communication with the processing circuitry, the transceiver configured to:
transmit to the WD an indication of the selected SS configuration to be configured by the WD, a bandwidth, center frequency and number of layers of transmission from the network node to the WD remaining unchanged by a change in search space configuration of the WD.
