Claim 11:
12. A base station comprising:
a controller and a transceiver;
wherein the controller is configured to:
control the transceiver to communicate with a user equipment (UE), using a first bandwidth part having a first bandwidth,
control the transceiver to transmit control data, to the UE, using a first control resource set associated with a common search space (CSS), wherein the first control resource set is conveyed in the first bandwidth part,
change to using a second bandwidth part having a second bandwidth for the communicating, wherein the second bandwidth is different from the first bandwidth, and
control the transceiver to transmit control data, to the UE, using a second control resource set associated with a CSS, wherein the second control resource set is conveyed in the second bandwidth part, and

wherein the second control resource set is different from the first control resource set in a frequency domain, and
respective frequency resource blocks of the first and second control resource sets are configured based on the respective first and second bandwidths.
