RADIO COMMUNICATION SYSTEM, RADIO COMMUNICATION DEVICE AND RADIO COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system capable of ensuring SINR (signal-to-interference and noise ratio) of an occupied bandpass by assigning a power density being different from that of the occupied bandpass to a shared bandpass, and improving a stable communication and a frequency utilization efficiency.SOLUTION: A radio communication system comprises: a plurality of base stations; and a plurality of terminal stations for communicating with the base stations, and in the system, a plurality of base stations communicate with a plurality of terminal stations via wireless lines while sharing same frequency bandpass. The base station comprises: a shared bandpass for allowing mutual interference by sharing a part or all of same frequency bandpass; bandpass assigning means for assigning a bandpass divided into the occupied bandpass which does not interfere with each other, by occupying a part of the same frequency bandpass, respectively; power assigning means for assigning different powers to each of the shared bandpass and the occupied bandpass; and date assigning means for arranging date in the shared bandpass and the occupied bandpass respectively.
