An efficient burst packing algorithm for OFDMA systems

Orthogonal Frequency Division Multiple Access (OFDMA) targets to provide broadband connectivity to wide area coverage in mobile environments, which results in significant design challenges in the Medium Access Control (MAC) layer to provide an efficient resource allocation in a cost-effective manner. This paper proposes a two dimensional (2D) Burst Packing (BP) algorithm for OFDMA down Link (DL) subframe that can provide the service providers with an efficient, fast, flexible and high spectral efficiency method to allocate system resources among the Mobile Stations (MSs). The proposed Orientation-Based Burst Packing algorithm uses the Orientation Factors (OF) of the bursts as a criteria to achieve the challenging issues in the BP problem. The simulation results show that the proposed algorithm can achieve a high packing efficiency up to 99.2 % when the burst size ratio (BSR) is 50 %.
