Dynamic power control in cellular systems has long been used for interference reduction, dynamic range control, and terminal battery savings. The analysis and numerical study, in shadow-fading environments, of power control algorithms based on received desired-signal levels are reported. Variational analysis of a simple case shows that compensation for 1/2 the dB value of path-loss variation is the optimal policy for S/I management, rather than the full-compensation algorithm. Simulations of more general cases verify this result and show the degree of robustness to errors and implementation constraints.
