Abstract:
1. A method of partitioning resource spaces and assigning physical channels and power in an OFDMA (orthogonal frequency division multiple access)-based cellular system which comprises a plurality of base stations and a plurality of cells associated with the base stations, said method comprising: (a) partitioning a resource within each slot of the cellular system into resource spaces, in common in adjacent cells of the cellular system; (b) further partitioning the partitioned resource spaces into resource sets according to respective sizes of physical channels in the adjacent cells, wherein the resource sets within one resource space of one of the adjacent cells are arranged to be collided as uniformly as possible with all the resource sets within the same resource space of another adjacent cell; (c) assigning the physical channels classified based on characteristics to the partitioned resource sets within the respective resource spaces; (d) allocating a transmit power of the resource space to a physical channel which, among the physical channels assigned to the resource set, uses a fixed transmit power; and (e) allocating a power within the maximum transmit power of the resource space to a physical channel which, among the physical channels assigned to the resource set, uses a variable transmit power.
