Abstract

This paper is to study the system level performance of LTE uplink and presents some evaluation methodologies. Joint orthogonal user grouping, proportional fairness scheduling and open loop power control are evaluated in Virtual MIMO single carrier -frequency division multiplexing access (SC-FDMA) systems. Open loop power control is proposed to use in the uplink of LTE. Simulation results show that open loop power control can improve the system throughput, lower system interference condition and satisfy the fairness criterion among users.
