In this paper, the problem of QoS-driven power control in the uplink of CDMA wireless networks supporting multiple services is considered. Due to the need for supporting simultaneously various services with diverse QoS requirements, users associated with a nested utility function which appropriately represents their degree of satisfaction in relation to the expected tradeoff between their QoS-aware actual uplink throughput performance and the corresponding power consumption. Based on this framework, the problem is formulated as a non-convex non-cooperative Multi-Service Uplink Power Control (MSUPC) game where users aim selfishly at maximizing their utility-based performance under the imposed physical limitations.
