Performance Analysis of Open Loop and Closed Loop Power Control Schemes for LTE Uplink

In multi user environment number of users share the same radio resources. A consequence of the limited availability of radio channels in the network is that the same channel has to be assigned to many users. Thus, a signal intended for a certain user will reach other users and introduce interference to their connection, and degrade the quality. This makes the Power Control functionality a vital issue. Power control needs to reduce inter-cell interference level at the same time achieve a required SINR level. The LTE power control mechanism constitutes of a closed loop component operating around an open loop point of operation.
