Abstract

In a mobile satellite communication system wherein a satellite (410) generates a plurality of spot beams, and both mobile stations and fixed terrestrial stations within the spot beams receive and transmit information on traffic channels (402) and command channels (401), two terrestrial stations (450A, 450B) are assigned a single set of common control channels (401,404,406, 408) for overlapping spot beams.
