Abstract--We consider an uplink power control
problem where each mobile wishes to maximize its
throughput (which depends on the transmission pow-
ers of all mobiles) but has a constraint on the average
power consumption. A finite number of power levels
are available to each mobile. The decision of a
mobile to select a particular power level may depend
on its channel state. We consider two frameworks
concerning the state information of the channels of
other mobiles: (i) the case of full state information
and (ii) the case of local state information. In each of
the two frameworks, we consider both cooperative as
well as non-cooperative power control. We manage to
characterize the structure of equilibria policies and,
more generally, of best-response policies in the non-
