Transmission power control method, communication device and program
First Claim
1. An electronic device, comprising:
- one or more antenna units; and
processing circuitry configured to;
obtain a request for secondary usage of a spectrum assigned to a first communication service, the request comprising location information of at least one secondary usage node; and
notify an acceptable transmission power level for a second communication service to the at least one secondary usage node, wherein the acceptable transmission power level is determined based, at least in part, on the location information.

Abstract
There is provided a method for controlling a transmission power in a second communication service making secondary usage of a spectrum assigned to a first communication service, with use of any node of one or more secondary usage node that transmits a radio signal of the second communication service, comprising the steps of: acquiring an acceptable interference power allocated to the second communication service; calculating a total sum of interference power levels on the first communication service based on transmission powers respectively required for the one or more secondary usage node; and excluding any secondary usage node of the one or more secondary usage node from allocation of the transmission power when the calculated total sum of interference power levels is larger than the acceptable interference power.

14. A secondary usage node, comprising:
-
one or more antenna units; and processing circuitry configured to; transmit a request for secondary usage of a spectrum assigned to a first communication service to a management node, the request for secondary usage comprising location information of the secondary usage node; and receive an acceptable transmission power level for a second communication service from the management node, wherein the acceptable transmission power level is determined based, at least in part, on the location information. - View Dependent Claims (15, 16, 17, 18, 19)
