1. A user equipment (UE) having a reduced bandwidth capability, the UE comprising:
a receiver configured to receive control resource set (CORESET) transmissions from a gNB, the CORESET transmissions following a frequency hopping pattern across a set of sub-bands, each sub-band of the set of sub-bands being a subset of a system bandwidth available from the gNB; and
processor circuitry configured to:
determine a sub-band location associated with the CORESET transmissions, the sub-band location determined from information received from a physical downlink control channel (PDCCH) transmission, and
control the receiver according to the determined sub-band location,
wherein the frequency hopping pattern is based on a randomization parameter for determination of each sub-band such that continuous PDCCH transmission blocking is avoided.
