Abstract

In this paper, the authors developed a new prioritization function integrated within a new resource allocation process for an OFDMA system. In this paper a new prioritization function is proposed where the resource allocation problem is divided in two phases; the minimum requirements satisfaction, and; the spectral efficiency maximization of the unallocated resources. Compared with the Proportional Fair (PFS) and the Prioritization Function (PRF) algorithms whose have been designed based on the average bit rate requirements without considering neither the states of the buffers or the VBR nature of the traffic, the proposed scheme overcome these restrictions by the support of a designed Packet Data Scheduler (PDS) based on the input buffers status.
