A spectrum sharing method is proposed for the systems which share the same frequency band or adjacent bands with different priorities. The proposed method adaptively controls transmission power according to information offered by high-priority system receivers. We give theoretical capacities achieved by low-priority systems when the proposed method and a conventional method are applied. As for the conventional method, a low-priority terminal is assumed to use constant transmit power and starts its transmission if it does not interfere high-priority systems. Numerical results confirm that the proposed method attains 1.5-2 times larger capacity than the conventional method. |
