BEAM MANAGEMENT IN A SATELLITE COMMUNICATION SYSTEM |
摘要 |
A method (400, fig. 4) for beam management in a satellite communication system (10) which simplifies cell-to-cell hand-offs within a footprint (90) of a satellite (20) and between two or more satellites (20) is disclosed. The method includes the steps of providing multiple beam stripes (130, fig. 2) extending across the footprint (90) in a direction corresponding to the direction of flight (60) of the satellite, grouping the beam stripes (130) into one or more beam groups (150, fig. 3), and selectively associating hardware groups (300) comprised of hardware resources to support beam groups (150). Method (400) also can include steps (450-470) for determining and compensating for undesirable system effects arising as a result of the relative motion of the Earth (50, fig. 1) with respect to satellites (20) of system (10). A satellite (20, fig. 10 and 11) designed and configured to execute method (400) also is disclosed.
