Power Control based Resource Allocation in LTE Uplinks

Abstract

Uplink power control is essential in 3GPP Long Term Evolution (LTE) to reduce interference caused by adjacent cell users and extending the user equipment (UE) battery life. In open loop power control, no feedback is given by the base station to the user equipments whereas in closed loop power control, feedback for power control is given by eNodeB to UE. Resource scheduling algorithm with power control technique is proposed in this paper, which considers channel characteristics and minimum power requirement at the base station for successful reception of a signal. Simulation results show that (i) the RBs are allocated to maximum UEs based on SINR and power control, (ii) the interference caused by the UEs in the adjacent cell is reduced thereby maximizing the uplink data rate.
