Communication control device, communication control method, communication device, communication method, and communication system
First Claim
1. A communication control device comprising:
- 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, anda 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;
a control unit configured to restrict transmission power for communication with another secondary communication node based on a power allocation result received by the communication unit.
