Patent ID: 7177645

Claim:
In a wireless system comprising a first plurality of wireless networks, each wireless network comprising at least one base station and at least one subscriber terminal associated therewith, wherein at least one of the communication links extending between at least one of a first plurality of base stations and one or more subscriber terminals adapted to communicate with said at least one base station, experiences interferences resulting from communications exchanged along at least one communication link comprised in a different wireless network, a method of allocating sub-frames within one or more communication time frames for eliminating said interferences, which method comprises: for each wireless network, classifying each of the operative links extending between its base station and the subscriber terminals associated therewith by the interferences to which said link would be subjected due to transmissions of communications in at least one other wireless network; allocating within one or more of the communication time frames designated for transmission and/or reception of communications along said first plurality of wireless networks, at least two sub-frames; determining which of the links will be allowed to carry communications during each of said at least two sub-frames, wherein the determination is made to satisfy a selection condition whereby none of the links associated with a certain sub-frame be subjected to interferences caused by communications transmitted along any of the other links carrying communications during that sub-frame; and communicating radio signals between each of the base stations and their respective one or more subscriber terminals during said at least two sub-frames, wherein the communication is carried in accordance with the determination step.
