Abstract
A method is presented for communicating data in a multibeam satellite system utilizing frequency re-use. The method comprises establishing uplink service beams and downlink service beams between a satellite and a plurality of subscriber terminals. A plurality of the uplink service beams are transmitted to the satellite by re-using at least one common uplink frequency channel. A plurality of the downlink service beams are transmitted from the satellite by re-using at least one common downlink frequency channel. The method further comprises establishing at least one uplink feeder beam and at least one downlink feeder beam between the satellite and a gateway terminal. The at least one uplink feeder beam is transmitted to the satellite by further re-using the at least one common uplink frequency channel. The at least one downlink feeder beam is transmitted from the satellite by further re-using the at least one common downlink frequency channel.
