Abstract
A communications system and method of operating the communications system includes a high altitude communication device that communicates with a plurality of user terminals and a gateway station. The gateway station couples the users to terrestrial networks and other users. The high altitude communication device has gateway station that assigns a first code to a beam of a first plurality of users. The gateway station continually determines whether an interference occurs between the first beam and the second beam by determining whether the first interference contour intersects the second interference contour when the first interference contour intersects the second interference contour. The gateway station declares an interference when the contours intersect and reassigns a second resource to the first beam.
