Abstract

A method and system for adjusting the transmission power of a transmitter during a communication with a receiver in a mobile satellite communication system is disclosed herein. The method comprises establishing at least one threshold signal strength value for a transmitted burst; measuring the received signal strength of the burst received by the receiver; comparing the received signal strength with the threshold value; and setting a power control bit based on the comparison. The system comprises a plurality of mobile terminals having a first stored threshold value; a satellite adapted to communicate with each of the mobile terminals; at least one gateway in communication with the satellite, the gateway having a second stored threshold value, and including a routine for measuring the received signal strength of a burst signal transmitted from the mobile terminal, for comparing the received signal strength with the second stored threshold value, and for adjusting the transmission power of the gateway based on the comparison; and each of the mobile terminals including a routine for measuring the received signal strength of a burst signal transmitted from the gateway to the mobile terminals, for comparing the received signal strength with the first stored threshold value, and for adjusting the transmission power of the mobile terminal based on the comparison.
