Patent ID: 8331398

Claim:
A method of constructing a resource allocation map in a case where a base station allocates a radio resource to a plurality of mobile terminals by using a localized resource block in a mobile communication system, the localized resource block being a localized sub-channel composed of neighboring sub-carriers, the method comprising: including, by the base station, a mobile terminal identifier column where identifiers of the mobile terminals are continuously displayed, in the resource allocation map; setting, by the base station, an index for each mobile terminal according to an order in which the mobile terminal identifiers are displayed, and allocating an index of a mobile terminal corresponding to each of resource blocks of the radio resource for each resource block, the resource block being a unit of a minimal radio resource found by dividing a radio resource used when data is transmitted; including, by the base station, an index bit pattern where indexes allocated for the individual resource blocks are arranged according to an order of the resource blocks included in the radio resource, in the resource allocation map, wherein the index for each mobile terminal and the index bit pattern are described in bit notation; and between the including of the mobile terminal identifier column in the resource allocation map, and the setting of an index for each mobile terminal and the allocating of an index of a mobile terminal for each resource block, determining, by the base station, the number of bits that form the index, wherein the number of bits that form the index is calculated, by the base station, by Equation {log 2 (M)}, where reference character M indicates the number of mobile terminals.
