Communication control device, communication control method, and wireless communication device for frequency sharing among high-priority wireless networks

A communication control method, comprising:

• in a first communication control device:
• controlling at least one first wireless communication device;
• acquiring, from a frequency management device, a right for a high-priority access of at least one frequency band of a spectrum;
• transmitting first information to a second communication control device, wherein
• the frequency management device is different from each of the first communication control device and the second communication control device,
• the at least one frequency band of the spectrum is assigned to the at least one first wireless communication device and at least one second wireless communication device,
• the at least one second wireless communication device is controllable by the second communication control device,
• the at least one frequency band is available for the high-priority access,
• the first information includes second information, and
• the second information corresponds to the at least one frequency band available for the high-priority access;
• receiving, from the second communication control device, third information indicating a location of installation of the at least one second wireless communication device, wherein the location of installation corresponds to one of an indoor location or an outdoor location;
• permitting the high-priority access for the at least one second wireless communication device in a case where the third information indicates the location of installation of the at least one second wireless communication device is the indoor location;
• and
• restricting the high-priority access for the at least one second wireless communication device in a case where the third information indicates the location of installation of the at least one second wireless communication device is the outdoor location.

• the at least one frequency band of the spectrum is assigned to the at least one first wireless communication device and at least one second wireless communication device,
• the at least one second wireless communication device is controllable by the second communication control device,
• the at least one frequency band is available for the high-priority access,
• the first information includes second information, and
• the second information corresponds to the at least one frequency band available for the high-priority access;
• receiving, from the second communication control device, third information indicating a location of installation of the at least one second wireless communication device, wherein the location of installation corresponds to one of an indoor location or an outdoor location;
• permitting the high-priority access for the at least one second wireless communication device in a case where the third information indicates the location of installation of the at least one second wireless communication device is the indoor location;
• and
• restricting the high-priority access for the at least one second wireless communication device in a case where the third information indicates the location of installation of the at least one second wireless communication device is the outdoor location.

A first wireless communication device, comprising:

• circuitry configured to:
• transmit a first message to a first communication control device, wherein
• the transmitted first message includes a first request for transmission of information to a second communication control device,
• the information is related to a frequency band of a spectrum available for access,
• the spectrum is assigned to a communication service,
• the frequency band is utilizable by a second wireless communication device,
• the frequency band is shared between the first communication control device and the second communication control device,
• the information corresponds to the frequency band shared between the first communication control device and the second communication control device,
• the first communication control device receives the first message from the first wireless communication device and transmits the first message to the second communication control device,
• the second communication control device transmits a second message to the second wireless communication device based on the first message,
• the transmitted second message includes a second request for activation of a component carrier for carrier aggregation, and
• the second wireless communication device is controllable by the second communication control device;
• receive a response from the second wireless communication device based on the second request,
• wherein the response indicates the activation of the component carrier;
• utilize the spectrum assigned to the communication service;
• and
• utilize the frequency band for the carrier aggregation based on the activation of the component carrier.
