Patent ID: 7388845

Claim:
A method of operating a transmitter in a cell which uses a set of tones to transmit into a first sector of said cell over a plurality of symbol times using tones from said set of tones, the cell including a second sector adjoining said first sector, said transmitter transmitting into said second sector on first and second communications channels, the first communications channel including a first subset of said set of tones during each of a first subset of said plurality of symbol times, the second communications channel including a second subset of said set of tones during each of said first subset of said plurality of times, said first subset of said set of tones and said second subset of said set of tones being different from each other during each symbol time, the method comprising: operating the transmitter to transmit on said first and second channels into said first sector in a synchronous manner with transmissions made by said transmitter into said second sector; and controlling a total transmission power of the tones corresponding to the first channel in the first sector during said first subset of said plurality of symbol times to be greater than 20% and less than 500% of a total power of the tones corresponding to the first channel transmitted into the second sector, during said first subset of said plurality of symbol times.
