Classification: CPC H | IPC H

Claim 13:
14. A communication system, comprising:
a master communication control device; and
a first slave communication control device and a second slave communication control device following the master communication control device, wherein
the first slave communication control device includes first circuitry that:
acquires a first spectrum grant request following a first scheme from a second radio system, of a plurality of second radio systems, that performs a wireless communication using a radio wave of a frequency band used by a first radio system, and
calculates a communication parameter of the second radio system under the first slave communication control device based on an interference margin notified from the master communication control device,
the second slave communication control device includes second circuitry that:
acquires a second spectrum grant request following a second scheme from the second radio system, of the plurality of second radio systems, that performs a wireless communication using a radio wave of a frequency band used by the first radio system, and
calculates a communication parameter of the second radio system under the second slave communication control device based on the interference margin notified from the master communication control device, and
the master communication control device includes circuitry that causes the slave communication control devices to calculate the communication parameters of the plurality of second radio systems under the first and second slave communication control devices, in a predetermined slave communication control device order.
