Abstract

We investigate the practicality of a proposed network-level resource-management scheme for reverse-link transmissions in multimedia wideband code-division multiple-access (WCDMA) communications. The inherently centralized algorithm manages all transmitted powers and rates and base-station assignments to guarantee quality of service while achieving a high spectral efficiency. Approximations make it less computationally complex and allow its partial decentralization. Preliminary simulation experiments and analysis of its sensitivity to path-gain estimation error show reasonable performance. Of interest is its potential combination with closed-loop power control in IMT-2000
