| 1. A method for allocating resources for individual sectors in an orthogonal frequency division multiplexing (OFDM) mobile
communication system, the method comprising the steps of:
dividing a hill subcarrier band into a first subcarrier region and a second subcarrier region having a same size;
allocating subcarriers selected from the first subcarrier region based on a first subcarrier allocation pattern as downlink
resources for sectors in a first service zone among a plurality of sectors included in one cell;
allocating subcarriers selected from the second subcarrier region based on a second subcarrier allocation pattern as downlink
resources for sectors in a second service zone; and
performing one of a first operation and a second operation when a load for a downlink in one of the sectors is greater than
a load for a downlink in a neighboring sector,
wherein the cell includes a predetermined number of sectors, the predetermined number is a multiple of 2 and is at least equal
to 6, and the sectors in the first service zone neighbor the sectors in the second service zone,
wherein the first operation comprises releasing downlink resources allocated for the neighboring sector and then reallocating
the released downlink resources as downlink resources for the one of the sectors, and the second operation comprises narrowing
an antenna beamwidth forming the one of the sectors and widening an antenna beamwidth forming the neighboring sector.
