Abstract

For OFDMA (Orthogonal Frequency Division Multiple Access)-based broadband systems, a frequency reuse factor of 1 has been highly desirable for more improved channel throughput However, the forward link capacity is rapidly decreased at the cell boundary region due to the increase in the ICI (InterCell Interference) This paper presents a QoS (Quality of Service) maintenance technique by measuring a SIR-based channel capacity and by performing a radio resource reservation at the initial service setup time In order to prove the effectiveness of the proposed algorithm, two difference radio resource management schemes are compared associated with multiple classes.
