Systems and method with different utilization of satellite frequency bands by a space-based network and an ancillary terrestrial network
First Claim
1. A method of operating a radioterminal communications system including a space-based network comprising a space-based component and an ancillary terrestrial network comprising at least one ancillary terrestrial component, the method comprising:
- preferentially communicating between the ancillary terrestrial network and a radioterminal over a first time interval using frequencies from a first and/or second satellite frequency band; and
preferentially communicating between the space-based network and the radioterminal over a second time interval using frequencies from the first and/or second satellite frequency band, wherein the first and second time intervals are non-overlapping.

Abstract
A radioterminal communications system includes an ancillary terrestrial component configured to receive from at least some of a plurality of radioterminals using frequencies from a first satellite frequency band (e.g., an L-band) and to transmit to at least some of the plurality of radioterminals using frequencies from a second satellite frequency band (e.g., an S-band). The system further includes a space-based component configured to communicate with the plurality of radioterminals using at least some of the frequencies from the first satellite frequency band and/or at least some of the frequencies from the second satellite frequency band. In some embodiments the ancillary terrestrial component communicates with radioterminals using a Time Division Duplex (TDD) mode and the space-based component communicates with the same or other radioterminals using a Frequency Division Duplex (FDD) and/or a TDD mode.
