Abstract
Provided are a dynamic resource allocation method based on frequency reuse partitioning for an Orthogonal Frequency Division Multiple Access (OFDMA) system, and a frame transmission method therefor. The dynamic resource allocation method includes: a) dividing a coverage into cells based on frequency reuse partitioning; b) selecting a candidate user to receive a channel allocated thereto based on the ratio; c) acquiring distance information for the candidate user; and d) checking whether the candidate user is in an inner or outer cell area based on the distance information. If the candidate user is in the inner cell area, a subchannel group among subchannel groups having a Frequency Reuse Factor (FRF) lower than a threshold value is selected and subcarriers of the selected subchannel group is allocated. If the candidate user is in the outer cell area, a subchannel group among subchannel groups having a FRF higher than the threshold value is selected.
