Patent ID: 7092732

Claim:
A radio-communication control method in the communication system wherein the user terminals which are requesting radio-communication are connected to the wired network via the access points, in which: the received powers of the signals transmitted from a plurality of access points are measured with user terminals and the desired signal pair interference power ratio is obtained from a ratio of the received power of signal at the access point to which a user terminal belongs to the received power of signal at the other access point; when said signal pair interference power ratio is larger than the predetermined signal pair interference power ratio, the user terminal is judged to exist within the non-interference domain; when said signal pair interference power ratio is smaller than the predetermined signal pair interference power ratio, the user terminal is judged to exist within the interference domain; the transmission time from the access point to a user terminal in the non-interference domain and to a user terminal in the interference domain is divided with time to respectively obtain a first time period and a second time period; simultaneous communications are performed, in said first time period, to a plurality of user terminals in the non-interference domain from a plurality of corresponding access points; and communications are performed on the time division basis, in said second time period, to the user terminals in the interference domain from a plurality of access points.
