Utility-Based Uplink Power Control in CDMA Wireless Networks with Real-Time Services
In this paper we address the problem of efficient power allocation in the uplink of CDMA wireless networks, emphasizing on the support of realtime services’ QoS prerequisites. The corresponding problem is formulated as a non-cooperative game where users aim selfishly at maximizing their utilitybased performance under the imposed physical limitations. A user’s utility reflects its degree of satisfaction with respect to its actual throughput performance, QoS requirements fulfillment, and the corresponding power consumption. The existence and uniqueness of a Nash equilibrium point of the proposed Uplink Power Control (UPC) game is proven, where all users have attained a targeted SINR value or transmit with their maximum power, leading essentially to an SINR-balanced network. The properties of equilibrium in a pure optimization theoretical framework are studied, and the tradeoffs between users’ overall throughput performance and real-time services strict QoS requirements in channel a...
