Abstract:In this paper we will study the architecture of the Long Term Evolution LTE of Universal Mobile Telecommunication System UMTS with Multi User Multiple Input Multiple Output MU-MIMO technique. Open-Loop Spatial Multiplexing OLSM is one of nine transmission modes in LTE networks, in OLSM transmissions are configured with minimal feedback from the UE; we will consider OLSM in this study while performing three different types of scheduling algorithms that are used in LTE. The implementation of this study will use MATLAB software with LTE system level simulation, and results will collected for UE's throughputs and compared with each other for the different types of schedulers and with different antenna configurations such as 2x2, 2x4, and 4x4.

“…Nevertheless, it is hard to derive useful conclusions since there is no reference or comparison to other admission control methods. Finally, there are various works on the scheduling phase of LTE that grant priority to the VoIP traffic service (Choi et al, 2007;Puttonen et al, 2008;Saha and Quazi, 2009). The main idea behind these contributions is that the prioritization of the voice packets takes place once the connection has been admitted in the system.…”

“…Nevertheless, due to the lack of delay and PLR thresholds, they are not suitable for supporting simultaneously real-time and non real-time traffic [2]. For group 4, authors in [8] proposed a priority mode for VoIP traffic over 3G LTE. In their scheduler, VoIP priority mode is executed when there is VoIP packet in the queue.…”

Abstract-The Long Term Evolution (LTE) is a high data rates and fully All-IP network. It is developed to support well to multimedia services such as Video, VoIP, Gaming, etc. So that, the real-time services such as VoIP, video, etc. need to be optimized. Nevertheless, the deployment of such live stream services having many challenges. Scheduling and allocating radio resource are very important in LTE network, especially with multimedia services such as VoIP. When voice service transmitted over LTE network, it is affected by many network impairments where there are three main factors including packet loss, delay, and jitter. This study proposes a new scheduler which is based on VoIP priority mode, Wideband (WB) E-model, QoS-and Channel-Aware (called WE-MQS-VoIP Priority scheduler) for voice services in LTE downlink direction. The proposed scheduling scheme is built based on the WB E-model and Maximum Queue Size (MQS). In addition, we integrate the VoIP priority mode into our scheduling scheme. Since the proposed scheduler considers the VoIP priority mode and user perception, thus, it improves significantly the system performance. The results demonstrate that the proposed scheduler not only meets QoS demands of voice calls but also outperforms Modified Largest Weighted Delay First (M-LWDF) in terms of delay, Packet Loss Rate (PLR) for all number of user (NU) and excepting NU equals 30, respectively. For Fairness Index (FI), cell throughput, and Spectral Efficiency (SE), the difference among the packet schedulers is not significant. The performance evaluation is compared in terms of Delay, PLR, Throughput, FI, and SE.
