Abstract:
1. A second base station for use in a second communications cell located adjacent a first communications cell in which a first base station transmits first and second carrier signals, the first carrier signal having a first carrier frequency with communication bandwidth, the second carrier signal having a second carrier frequency with communications bandwidth, the second carrier frequency being different from the first carrier frequency, a first amount of power being allocated by the first base station for transmitting the first carrier signal and a second amount of power being allocated by the first base station to transmit the second carrier signal, the first amount of power being less than the second amount of power, the second base station comprising: means for transmitting a third carrier signal and a fourth carrier signal, the third carrier signal having the same carrier frequency as said first carrier signal, the fourth carrier signal have the same carrier frequency as said second carrier signal; and means for allocating transmission power to the third and fourth carrier signals to maintain a power difference between said third and fourth carrier signals, the transmission power allocated to the third carrier signal being greater than the transmission power allocated to the fourth carrier signal.
