Performance Analysis of Scheduling Strategies in LTE based on Open-Loop Spatial Multiplexing MU-MIMO Transmission Mode

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 UEs throughputs and compared with each other for the different types of schedulers and with different antenna configurations such as 2x2, 2x4, and 4x4.
