Abstract
There is provided a doing apparatus including a communication control device including a power allocation unit configured to allocate transmission power for secondary use of a frequency channel protected for a primary system to a secondary system. The power allocation unit switches power allocation methods between a first group of secondary systems of which a distance from the primary system is less than a prescribed threshold and a second group of secondary systems of which a distance from the primary system exceeds the prescribed threshold.
Claims12
A communication control device comprising
- a power allocation unit configured to:
- obtain information on a primary system from a server;
- obtain information on a secondary system;
- calculate a distance of the secondary system from the primary system based on the obtained information;
- classify the secondary system into a first group of which the distance from the primary systems is less than a prescribed threshold and a second group of which the distance from the primary system exceeds the prescribed threshold;
- allocate a transmission power to the first group with a first power allocation method;
- and
- allocate a transmission power to the second group with a second power allocation method,
- wherein the first power allocation method has a greater computational cost than that of the second power allocation method.
A method for allocating transmission power for secondary use of a frequency channel protected for a primary system to a secondary system, the method comprising:
- obtaining information on a primary system from a server;
- obtaining information on a secondary system;
- calculating a distance of the secondary system from the primary system based on the obtained information;
- classifying the secondary system into a first group of which the distance from the primary systems is less than a prescribed threshold and a second group of which the distance from the primary system exceeds the prescribed threshold;
- allocating a transmission power to the first group with a first power allocation method;
- and
- allocating a transmission power to the second group with a second power allocation method,
- wherein the first power allocation method has a greater computational cost than that of the second power allocation method.
A computer readable medium on which a program is stored for causing a computer of a communication control device to function as
- a power allocation unit configured to:
- obtain information on a primary system from a server;
- obtain information on a secondary system;
- calculate a distance of the secondary system from the primary system based on the obtained information;
- classify the secondary system into a first group of which the distance from the primary systems is less than a prescribed threshold and a second group of which the distance from the primary system exceeds the prescribed threshold;
- allocate a transmission power to the first group with a first power allocation method;
- and
- allocate a transmission power to the second group with a second power allocation method,
- wherein the first power allocation method has a greater computational cost than that of the second power allocation method.
