We study power control in multicell CDMA wireless networks
as a team optimization problem where each mobile
attains its individual fixed target SIR level by transmitting
with minimum possible power level. We derive conditions
under which the power control problem admits a unique
feasible solution. Using a Lagrangian relaxation approach
similar to [8] we obtain two decentralized dynamic power
control algorithms: primal and dual power update, and establish
their global stability utilizing both classical Lyapunov
theory and the passivity framework [12]. We show
that the robustness results of passivity studies [6, 7] as well
as most of the stability and robustness analyses of [8] in
the literature are applicable to the power control problem
considered. In addition, some of the basic principles of call
admission control are investigated from the perspective of
the model adopted in this paper. We illustrate the proposed
power control schemes through simulations.
