Abstract
Measurements of mobile signal strength received at the base station are used to determine the portion of power that should be transmitted by the base station to a particular mobile. Each of a plurality of mobiles measure the relative strength of the base station signal specifically intended for that mobile. The relative strength is compared to either the total base station signal power or to a cumulative ranking of the power of signals intended for other mobiles. That comparison is used to determine whether the mobile should increase or decrease its power.
