Optimal SIR-Based Power Control Strategies for Wireless CDMA Networks
Overview One aspect of the wireless communications power control problem that has received little attention is the designs of control algorithms that explicitly consider the tradeoff between the costs of transmit power and SIR error. This paper proposes a novel optimal control algorithm for distributed power control in cellular communication systems. The paper assumes that each mobile acts independently. The interference caused by the transmissions of mobiles in other cells is lumped with the background interference. The paper defines a cost for each mobile that consists of a weighted sum of power, power update, and Signal-to-Interference Ratio (SIR) error and obtain the corresponding optimal control law assuming the interference value does not change significantly from one measurement to the next.
