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.

[ What is claimed is:] [1.] A method of adjusting transmission power of a transmitter during a communication with a receiver, said transmitter transmitting a burst signal to said receiver, said method comprising the steps of:broadcasting an upper threshold signal strength value, a lower threshold signal strength value, and a nominal signal quality value to the receiver;measuring a received signal strength of said burst signal received by said receiver;developing a signal quality value for said burst signal received by said receiver;setting a power control bit to a first value if said received signal strength is lower than said lower threshold signal strength value;setting said power control bit to a second value if said received signal strength is higher than said upper threshold signal strength value;setting said power control bit to the first value if said signal quality value is lower than said nominal signal quality value and said received strength signal is both higher than said lower threshold signal strength value and lower than said upper threshold signal strength value; and,setting said power control bit to the second value if said signal quality value is higher than said nominal signal quality value and said received strength signal is both higher than said lower threshold signal strength value and lower than said upper threshold signal strength value.
