A system and method for controlling the strength of a shared resource sign al transmitted by the satellite transponder (104) in a satellite communications system. The satellite communications system includes a gateway (102) for transmittin g communications signals including a shared resource signal (402), a satellit e transponder (104) for relaying (404) the signals to at least one subscriber unit (106A, B, C) (for example, a phone), and at least one subscriber unit (106) for receiving the signals (406). The method includes the steps of receiving the shared resource signal (406), at each subscriber unit (106), via the satellite transponder (104); measurin g (408), at each subscriber unit (106), a signal strength for the received shared resour ce signal; sending the signal strengths to the gateway (410, 102); and adjusting the power of the shared resource signal transmitted by the satellite transponder (418) based on the signal strengths.
