Abstract	We propose a scheme of optimal resource management for reverse-link transmissions: in multimedia wideband code-division multiple-access (WCDMA) communications. It is to guarantee quality of service (QoS) by resource allocation (transmitted power and rate) and achieve high spectral efficiency by base-station assignment. The approach takes the form of a nonlinear-programming large-scale optimization problem: maximizing an abstraction for the profit of a service provider subject to QoS satisfaction. Due to its max-max structure, solving the optimization problem directly entails a high computational complexity. Instead, the problem is reformulated to: a mixed integer nonlinear-programming (MINLP) problem. Then, binary variables indicating base-station assignments are relaxed to their continuous analogs to make a computer solution feasible. Preliminary simulation results show the effectiveness in a multicell network.
