Abstract

Claims (40)

1 . A communication control device comprising:

control circuitry that;

controls a receiver to receive, from a secondary use communication device that provides a secondary communication service, a request for using at least a part of a frequency band that is used by a primary communication service the request including information regarding a secondary use communication device group that includes the secondary use communication device; and

in response to the request:

generates a first response code according to a result of a judgment regarding the requested use of the frequency band;

generates, based on the result of the judgment, a second response code regarding the requested use of the frequency band in the secondary use communication device group; and

controls a transmitter to transmit a response signal that includes the first response code and the second response code to the secondary use communication device.

2 . The communication control device according to claim 1 ,

wherein the control circuitry makes the judgement based on protection of the primary communication service in use of the frequency band in the request.

3 . The communication control device according to claim 2 ,

wherein the control circuitry makes the judgement based on protection of the primary communication service against interference in the use of the frequency band in the request.

4 . The communication control device according to claim 1 ,

wherein the first response code is classified into a response code group which groups a plurality of responses corresponding to and related to the result of the judgment, and

the control circuitry generates the second response code based on the response code group.

5 . The communication control device according to claim 1 ,

wherein a secondary use communication device group is configured as a coexistence group, and

the second response code includes information related to the coexistence group.

6 . The communication control device according to claim 5 , wherein the second response code indicates a state in which the secondary use communication device and another secondary use communication device in the coexistence group are asynchronous with each other.

7 . The communication control device according to claim 5 ,

wherein the second response code indicates exclusion of the secondary use communication device from the coexistence group.

8 . The communication control device according to claim 5 , wherein the control circuitry generates a response code indicating a state of crosslink interference between the secondary use communication device and another secondary use communication device in the coexistence group.

9 . The communication control device according to claim 5 ,

wherein the second response code indicates invalidity of at least a part of subgroup information regarding the coexistence group.

10 . The communication control device according to claim 5 ,

wherein the second response code indicates incompatibility of the requested frequency band with an allocated band of the primary communication service.

11 . The communication control device according to claim 5 ,

wherein the second response code indicates a change in configuration information transmitted when the use of the secondary use communication device is determined.

12 . A secondary use communication device comprising:

a transmitter that transmits a request for using at least a part of a frequency band that is used by a primary communication service in order to perform a secondary use communication service using the frequency band, to a communication control device that controls use of the frequency band; and

a receiver that receives from the communication control device based on the request, a response signal that includes:

a first response code generated by the communication control device according to a result of a judgment related to the requested use of the frequency band, and

a second response code that is generated by the communication control device based on the judgment, the second response code including information related to the requested use in a secondary use communication device group that includes the secondary use communication device.

13 . The secondary use communication device according to claim 12 ,

wherein the transmitter transmits the request corrected in accordance with the received second response, to the communication control device.

14 . A communication control method performed by a communication control device and comprising:

receiving, from a secondary use communication device that provides a secondary communication service, a request for using at least a part of a frequency band that is used by a primary communication service, the request including information regarding a secondary use communication device group that includes the secondary use communication device; and

in response to the request:

generating a first response code according to a result of a judgment regarding the requested use of the frequency band;

generating, based on the result of the judgment, a second response code regarding the requested use of the frequency band in the secondary use communication device group; and

transmitting a response signal that includes the first response code and the second response code to the secondary use communication device.
