Abstract
Quality of Service (QoS) requirements, such as fairness, transmission power, average throughput and spectral efficiency, are a set of the important parameters that assess the performance of scheduling algorithms. One of the crucial goals of future cellular systems is to minimize transmission power while increasing system performance. Long Term Evolution-Advanced (LTE-A) is the most viable wireless broadband network that strongly supports QoS by using Admission Control (AC) and Packet Scheduling (PS). In LTE-A, Proportional Fair (PF) scheduling algorithm and its modified versions have proved to be the commonly used scheduling algorithms for their ability to provide fairness while Best Channel Quality Indicator (CQI) scheduling algorithm guarantees high throughput. This thesis presents uplink scheduling algorithm called, Modified Proportional Fairness Scheduling (MPF-BCQI) Algorithm with Best CQI consideration, by considering a tradeoff balance between throughput and fairness among users by combining Best CQI and PF schedulers’ metrics. Moreover, we enhance the PF scheduler performance using proposed averaging methods namely; median, range and geometric mean for computing the average throughput which is further used to determine the scheduling priority. IV The performance evaluation is presented using Vienna system level simulator. The results reveal that the performance of the proposed scheduler, with the proposed averaging methods in PF, gives better performance than the compared-to original schedulers as fairness is increased by 63% compared to the original Best CQI, average throughput is increased by 6.16% compared to the original Proportional Fairness and spectral efficiency is increased by 3.7% compared to the original Proportional Fairness.
