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.

Claims

1. A transmission power control method enabling secondary usage by a second communication service of a communication spectrum primarily assigned to a first communication service, the method comprising:

receiving a beacon for the second communication service;

acquiring location data associated with the second communication service; and

transmitting a signal for the second communication service based on the acquired location data.
