摘要
We present a model for efficient and robust power control in the downlink of Wideband CDMA wireless systems. The model is based on microeconomics, and takes into account both the congestion, in terms of increased interference, that a mobile user imposes to other users, and the downlink resource constraint, which involves the total transmission power at the base station. We discuss the application of the model for supporting service differentiation, and investigate various alternatives and their corresponding tradeoffs. Our approach involves adjusting the target signal quality based on weights declared by mobile users.
