“…In addition, the scheduling algorithm must also consider fairness and QoS requirements of users' service. Previous works in [13]- [16] investigated the influence of several scheduling algorithms with variety designs intended to improve the data rate, fairness, and QoS in the downlink LTE system.…”

LTE is the next step of the broadband cellular technology evolution. It is referred as the fourth generation (4G) technology which offers better performance in throughput, latency, and spectral efficiency. It uses OFDM that is proven to combat inter-symbol-interference (ISI), multipath fading, and enabling scalable bandwidth allocation. Downlink LTE uses OFDM technology variation called OFDMA which enables multiple users accessing system resources at the same time. The increasing demand of real time services with larger bandwidth requirement makes the utilization of scheduling algorithms to manage system resource is very important. A scheduling algorithm which resides in eNB plays a key role in optimizing network capacity, throughput, and cell edge performances. The Proportional Fairness algorithm offers a good trade-off between total throughput and fairness values for users handled in the network. In this paper, we use Proportional Fairness algorithm with adaptive bandwidth allocation in LTE downlink system in order to improve scheduler performance when handling real time video service. The simulation results show that the proposed algorithm is able to increase system performance in terms of throughput, delay, and fairness.

“…This equation results in Pareto optimal condition, hence when scheduling a user, the vector rate change of -th user should meet the following equation: (9) Using this equation, system stability can be achieved if the following matrix equation selects every user: (10) Where is the -th user's average data rate in the previous time slot. This equation results in a good trade-off between system throughput and fairness, but when implementing it in real time services result in high packet delay violation [17] since the delay is not considered in this matrix calculation.…”

Scheduling algorithm is one of many ways to increase system capacity and Quality of Service (QoS) in a telecommunication network. Designing a scheduling algorithm for a wireless network is challenging because its channel condition changes randomly according to the user's position. This paper investigated the performance of our proposed scheduling algorithm when managing multi-service flows in the downlink LTE network. The algorithm is the improvement of Proportional Fairness (PF) algorithm. The Extended-PF algorithm is a channel-aware scheduling algorithm that exploits users' channel condition information for calculating scheduling matrix in every scheduling process. Our simulation results showed that our proposed algorithm was able to provide better system's spectral efficiency.
