Claim of US Patent No. 10,142,995

1. A master node of a second wireless communication system which is secondarily operated based on a first frequency channel used by a first wireless communication system, the master node comprising:a power control unit configured to:
request a transmission power allocation from a communication control device;
transmit information associated with a position of the master node to the communication control device;
receive a response from the communication control device, wherein the response includes a given transmission power allocation for the second wireless communication system;
determine that the second wireless communication system is permitted to operate and the given transmission power allocation is proper; and
set the given transmission power allocation to a wireless communication unit based on the determination,
wherein the given transmission power allocation is based on an interval between a reference point of the first wireless communication system and the master node, wherein the interval satisfies a condition, and
wherein the condition is based on a guard area for the first wireless communication system and a communication distance associated with the second wireless communication system.
