1. A transmission control method comprising:
- enabling secondary usage by a second communication service of a communication spectrum primarily assigned to a first communication service by;
determining whether transmission of a notification signal associated with the second communication service is available;
in response to determining that transmission of the notification signal associated with the second communication service is not available, waiting to transmit the notification signal until transmission of the notification signal associated with the second communication service becomes available; and
transmitting the notification signal indicating an acceptable transmission power for the second communication service which does not cause interference to the first communication service.

Abstract
There is provided a communication device including: a communication unit that receives a beacon for a second communication service making secondary usage of a spectrum assigned to a first communication service; and a control unit that controls a transmission power to be used for transmission of a radio signal of the second communication service from the communication unit based on location data included in the beacon and indicating a location of a transmission source node of the beacon and a location of an interfered node interfered by the second communication service.
