Communication control device, communication control method, communication device, communication method, and communication system
First Claim
1. A communication control device comprising:
- a circuitry configured to;
make communication with one or more secondary communication nodes operating a secondary system using at least one of a frequency channel allocated to a primary system or a frequency channel adjacent to the frequency channel;
determine a first upper limit number of frequency channels allocated to the primary system;
allocate transmission power to each secondary system or each secondary communication node in each secondary system based on the determined first upper limit number per frequency channel used by the secondary system; and
restrict transmission power based on a power allocation result.

Abstract
Provided is a communication control device including a communication unit configured to make communication with one or more secondary communication nodes operating a secondary system using at least one of a frequency channel allocated to a primary system and a frequency channel adjacent to the frequency channel, a determination unit configured to determine an upper limit number of secondary systems or secondary communication nodes to be allocated with transmission power, and a power allocation unit configured to allocate transmission power to each secondary system or each secondary communication node in each secondary system based on the determined upper limit number and the acceptable interference amount of the primary system.

15. A communication control method using a communication control device for making communication with one or more secondary communication nodes operating a secondary system by use of at least one of a frequency channel allocated to a primary system or a frequency channel adjacent to the frequency channel, comprising:
-
determining a first upper limit number of frequency channels allocated to the primary system; allocating transmission power to each secondary system or each secondary communication node in each secondary system based on the determined first upper limit number per frequency channel used by the secondary system; and restricting transmission power based on transmission power allocation. - View Dependent Claims (16, 17, 18, 19)

20. A communication device operating a secondary system by use of at least one of a frequency channel allocated to a primary system or a frequency channel adjacent to the frequency channel, comprising:
a circuitry configured to; receive a transmission power allocation result from a communication control device configured to allocate transmission power to each secondary system or each secondary communication node in each secondary system based on an upper limit number of secondary systems or secondary communication nodes to be allocated with transmission power; and restrict transmission power based on the transmission power allocation result.
