Abstract
Communications are conducted between a space-based component of the wireless communications system and radioterminals using a plurality of forward link cells and a plurality of return link cells, the return link cells having a greater number of cells per frequency reuse cluster than the forward link cells. At least some of the forward and return link cells may use at least some frequencies of a terrestrial wireless communications system having an adjacent and/or overlapping coverage area. Forward links of the at least some of the forward and return link cells may have a greater link bandwidth than return links of the at least some of the forward and return link cells.
Claims53
A method of operating a wireless communications system, the method comprising:
- communicating between a space-based component of the wireless communications system and radioterminals using a plurality of forward link cells and a plurality of return link cells, the return link cells having a greater number of cells per frequency reuse cluster than the forward link cells, wherein at least some of the forward and return link cells use at least some frequencies of a terrestrial wireless communications system having an adjacent and/or overlapping coverage area.
A wireless communications system comprising:
- a space-based component configured to communicate with radioterminals using a plurality of forward link cells and a plurality of return link cells, the return link cells having a greater number of cells per frequency reuse cluster than the forward link cells, at least some of the forward and return link cells use at least some frequencies of a terrestrial wireless communications system having an adjacent and/or overlapping coverage area.
A wireless communications system comprising:
- a space-based component configured to communicate with radioterminals using a plurality of forward link cells and a plurality of return link cells the return link cells having a greater number of cells per frequency reuse cluster than the forward link cells;
- and
- an ancillary terrestrial component adjacent and/or overlapped at least some of the forward link cells and the return link cells and configured to communicate with radioterminals using at least some frequencies used by the at least some of the forward and return link cells.
A terrestrial wireless communications system comprising at least one station configured to communicate with radioterminals in a coverage area adjacent and/or overlapped by forward link cells and return link cells served by a space-based component of a mobile satellite communication system, wherein the return link cells have a greater number of cells per frequency reuse cluster than the forward link cells and the at least one station of the terrestrial wireless communications system is configured to use at least some frequencies used by the forward and return link cells.
