Communication control method, communication device, and program

A communication device comprising:

• a communication unit to transmit and receive radio signals for a second communication service making secondary usage of a spectrum assigned to a first communication service;
• and
• a control unit to control communication by the communication unit, wherein the control unit:
• controls the communication unit to receive a radio signal transmitted for the first communication service in a first period on a time axis,
• determines a parameter value to be used for controlling communication of the second communication service based at least in part on the radio signal received in the first period,
• senses for a radio signal transmitted for the second communication service through the communication unit during a second period subsequent to the first period, and
• controls the communication unit to transmit a beacon for the second communication service based at least in part on the parameter value in a third period subsequent to the second period when a radio signal for the second communication service is not detected in the second period.

At least one storage storing executable instructions that, when executed by a computer that controls a communication device including a communication unit that is able to transmit and receive a radio signal for a second communication service making secondary usage of a spectrum assigned to a first communication service cause the computer to function as:

• a control unit to control communication by the communication unit, the control unit executing a process including:
• controlling the communication unit to receive a radio signal transmitted for the first communication service in a first period on a time axis;
• determining a parameter value to be used for controlling communication of the second communication service based at least in part on the radio signal received in the first period;
• sensing for a radio signal transmitted for the second communication service through the communication unit during a second period subsequent to the first period;
• and
• controlling the communication unit to transmit a beacon for the second communication service based at least in part on the parameter value in a third period subsequent to the second period when a radio signal for the second communication service is not detected in the second period.
