A Novel Method For Downlink Frequency Allocation For Next Generation Wireless Networks
Abstract
Cellular systems such as 802.16e (Wi-max) and 3GPP Long Term Evolution (LTE) and all other currently
emerging technologies are based on orthogonal frequency division multiple access (OFDMA). OFDMA is basically a
combination of FDM and TDM. OFDMA suffers from heavy inter cell interference from the neighboring base stations
because they use the same frequency range, especially those who are in edge suffer from heavy inter cell interference. The
proposed scheme consists of ICIC management and fine PRB allocation by using simple and effective graph based
framework. Simulation results show that the proposed algorithm can achieve utilization of spectrum efficiently and
effectively while maintaining balanced performance between cell edge and cell center users in multi cell networks. Therefore
realize the goal of future wireless networks in terms of providing high performance to anyone from anywhere.
