Abstract:
1. A method for reducing multi-cell interference in a wireless communication system, the wireless communication system having a first base station whose communication signals with its covered terminals are interfered by communication signals transmitted between at least one interfering base station and its covered terminals, the method comprising; configuring, by the first base station, at least one inactive time slot in a transmit frame during which communications with its covered terminals are detectably reduced while communications between the at least one interfering base station and its covered terminals are maintained as normal; and detecting characteristics of interfering signals generated by the communications between the at least one interfering base station and its terminals during the inactive time slot; canceling the interfering signals by increasing a signal to interference and noise ratio of communication signals transmitted between the first base station and its terminals during the remaining portion of the transit frame based on the detected characteristics of the interfering signals.
