Abstract

Radio communication system includes terminal including unit detecting radar wave transmitted through second-frequency channel, first-and-second-frequency channels through which radar wave fails to be transmitted being simultaneously utilized or one of first-and-second-frequency channels being utilized, unit generating radar-detection information including information indicating detection time when detecting unit detects radar wave, and information indicating frequency channel through which radar wave is transmitted, and unit transmitting radar-detection information, and base station including unit receiving radar-detection information, unit generating radar-occurrence information based on received-radar-detection information, radar-occurrence information including information indicating occurrence time when radar wave occurs, information indicating period of occurrence of radar wave, and information indicating frequency channel through which radar wave is transmitted, and unit transmitting radar-occurrence information, terminal further including unit receiving radar-occurrence information, and unit communicating with other terminals through second-frequency channel without using ba…
