Abstract
A load shedding method and apparatus to enhance uplink margin between a terrestrial terminal (14) and a satellite (12) in a satellite based communications system (10) is provided. The terrestrial terminal (14) includes a multi-carrier network (40) that generates a plurality of uplink carrier channels. A RF transmit and receive system (48) transmits the plurality of uplink carrier channels to the satellite (12). A terminal control unit (46) determines an attenuation level on the plurality of uplink carrier channels transmitted to the satellite (12). The terminal control unit (46) also instructs the multi-carrier network (40) to increase or decrease the number of uplink carrier channels to be transmitted to the satellite.
