Abstract EN
Orthogonal Frequency Division Multiplexing (OFDM) with dynamic scheduling and resource allocation is a key component of most emerging broadband wireless access networks such as Worldwide Interoperability for Microwave Access (WiMAX) and Long Term Evolution (LTE).
Resource allocation mechanisms in LTE are very critical issues, because scheduling algorithms have the main responsibility for determining how to allocate radio resources for different users.
In this paper a dynamically adapted Proportional Fair (PF) scheduling algorithm for capacity enhancement of LTE system is proposed.
Performance comparison with the conventional PF downlink scheduler, which is characterized by high fairness but with low throughput, and the Best-Channel Quality Indicator( Best-CQI) scheduling algorithm which is characterized by high throughput but with poor fairness performance is presented.
Simulation results show that the proposed algorithm enhances the overall system capacity and also provides fairness in the distribution of the resources.
The proposed algorithm improves the average cell throughput by more than 31 %, with a slight degradation in the fairness level as compared with the conventional Proportional Fair PF scheduling algorithm
