Patent ID: 8116780

Claim:
A dynamic resource allocation method based on a frequency reuse partitioning, the method comprising the steps of: a) dividing a signal reception coverage into cells based on a frequency reuse partitioning method; b) acquiring a ratio of a summation of transmission rates that have been allocated to a user in a current position of a cell to a transmission rate requested by the user, and selecting a candidate user to receive a channel allocated thereto based on the ratio; c) acquiring distance information for the selected candidate user to receive the channel allocated thereto; and d) checking whether the selected candidate user is in an inner cell area or an outer cell area based on the acquired distance information, and if the candidate user is in the inner cell area, selecting a subchannel group among subchannel groups having a Frequency Reuse Factor (FRF) lower than a predetermined threshold value and allocating subcarriers of the selected subchannel group, or if the candidate user is in the outer cell area, selecting a subchannel group among subchannel groups having a FRF higher than the threshold value and allocating subcarriers of the selected subchannel group.
