Abstract

In 4G technology especially LTE relaying and orthogonal frequency division multiple access (OFDMA) are widely accepted techniques in downlink. To obtain ubiquitous coverage with high data rate to user terminals even in difficult channel conditions (e.g. cell edge) a centralized RRM algorithm has been proposed for cellular fixed relay networks in downlink OFDMA. The proposed method provides the fairness for user with minimal impact on network throughput. The average user throughput has been calculated for various bit error rate in this method. This method is queue aware and jointly performs three functions namely dynamic routing, fair scheduling and load balancing among cell nodes. This method is different from others because of its low level of complexity. Interference is analyzed between CDMA – DS base station and OFDMA base station. Additional isolation required and path losses are calculated when the two stations are not co-sited.
