Abstract:
1. A method for reducing multi-cell signal interferences in a wireless communication network, the method comprising: dividing an available frequency spectrum into a plurality of channels; segregating a first wireless communication coverage unit into a first number of geographical segments; grouping the channels into a second number of channel blocks; assigning each channel block to at least one of the segregated geographical segments with predetermined priorities; and repeating the above steps for each neighboring wireless communication coverage unit of the first wireless communication coverage unit, wherein the channels in different channel blocks exhibit no higher mutual interference than the channels in the same channel block, and wherein the channel block assigned for each segregated segment of the first wireless communication coverage unit is different from the channel block assigned for the segregated segment of a second wireless communication coverage unit that immediately borders with the segregated segment of the first wireless coverage unit even if the first and second wireless communication coverage units share the same frequency spectrum, wherein a location of a wireless terminal entering the first wireless communication coverage unit is detected by utilizing one or more segregated access code channels (ACCs) for the segregated geographical segments of the first wireless communication coverage unit to identify the wireless terminal wherein the ACCs and the segments bear a one-to-one relationship.
