Abstract

Power and spectrum are limited resource, so always we needed efficient control techniques to handle them in every generation. In this paper an efficient uplink power control algorithm is proposed for LTE-Advanced relay networks to improve coverage area. It is a co-operative power control method. It is developed using the utility function concept that belongs to economic theory. This algorithm is a distributed one, which is to be set up in mobile stations operating at 3GPP LTE or LTE-Advanced relay networks. In this the Lagrangian equation is used to solve the utility function to achieve optimal power control in the network. The outage probability analysis is carried out for the coverage area determination. It is observed that the proposed algorithm improves the cell edge user performance by maintaining the defined power levels in every mobile, improves the base station coverage area and decreases the interference level in the network.
