Abstract
Provided is a method for evaluating spectrum utilization efficiency in a radio system sharing frequency. The method for evaluating spectrum utilization efficiency of a frequency sharing radio system in a radio environment having a first radio system using at least one specific frequency in an allocated frequency band and a second radio system sharing the frequency band allocated by the first radio system, includes calculating net coverage per unit area based on a design parameter on the first radio system and a design parameter on the second radio system; and evaluating spectrum utilization efficiency based on the calculated net coverage per unit area.

A method for evaluating spectrum utilization efficiency of a frequency sharing radio system in a radio environment having a first radio system using at least one specific frequency in an allocated frequency band and a second radio system sharing the frequency band allocated by the first radio system, comprising:
- calculating a net coverage per unit area based on a design parameter of the first radio system and a design parameter of the second radio system;
- and
- evaluating spectrum utilization efficiency based on the calculated net coverage per unit area.
A method for evaluating spectrum utilization efficiency of a frequency-sharing radio system in a radio environment having a first radio system using at least one specific frequency in an allocated frequency band and a second radio system sharing the frequency band allocated to the first radio system, comprising:
- calculating a sum of coverage by frequency sharing based on a design parameter of the first radio system and a design parameter of the second radio system;
- calculating a net coverage by subtracting the region overlapped according to the frequency from the addition of the calculated coverage;
- and
- evaluating spectrum utilization efficiency based on the calculated net coverage.
