Abstract
We study power control in multicell CDMA wireless net-
works as a team optimization problem where each mobile
attains at the minimum its individual fixed target SIR level
and beyond that optimizes its transmission power level ac-
cording to its individual preferences. We derive conditions
under which the power control problem admits a unique
feasible solution. Using a Lagrangian relaxation approach
