Transmission power determination method, communication device and program

摘要

There is provided a method for determining an acceptable transmission power for a second communication service making secondary usage of a spectrum assigned to a first communication service, comprising the step of determining the acceptable transmission power based on quality of a radio signal required in the first communication service, an interference level or a noise level in the first communication service, and a path loss on a communication path about one or more secondary usage node that transmits a radio signal of the second communication service.

1. A method for determining a communication mode information for a second communication service making secondary usage of a spectrum assigned to a first communication service, the method comprising:
determining the communication mode information based on a quality of a first radio signal required in the first communication service, an interference level or a noise level in the first communication service, and a path loss information on a communication path about one or more secondary usage nodes that transmit a second radio signal of the second communication service; acquiring location data from a database that stores the location data indicating a location of a primary usage node that receives the first radio signal of the first communication service; and calculating the path loss information on the communication path about the one or more secondary usage nodes based on the location of the primary usage node indicated by the location data and a location of the one or more secondary usage nodes.
