1. A method of permitting real-time borrowing of carriers in a cellular communication system having a plurality of distinct carriers, the cellular communication system having a plurality of substantially similar cell clusters, each cell cluster having a plurality of cells wherein each cell has at least one base station capable of sending and receiving transmissions, each cell having a plurality of adjacent cells, the method comprising the steps of:

  • determining a total number of distinct carriers (CT) available for use by the cellular communication system, the total number of distinct carriers being at most equal to the plurality of distinct carriers;

    specifying a cell cluster size (N) for the cellular communication system where N=the number of cells in a cell cluster;

    selecting N disparate groups of carriers from the total number of distinct carriers, each carrier within the N disparate groups of carriers being substantially distinct from any other carrier within the N disparate groups of carriers;

    respectively assigning the N disparate groups of carriers to the N cells of each cell cluster wherein one carrier group is assigned to each cell; and

    segmenting the group of carriers assigned to each respective cell into a plurality of carrier subgroups assigned for lending to a predetermined adjacent cell, the number of carrier subgroups respectively corresponding to at least the plurality of adjacent cells, the carriers of each of the carrier subgroups being respectively designated for lending from the respective cell to said predetermined adjacent cell.
