SYSTEMS AND METHODS 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 communications system including a space-based network comprising a satellite and a terrestrial network comprising a base station, the method comprising:
- receiving communications at the base station from a radioterminal using frequencies from a first satellite frequency band;
communicating from the base station to the radioterminal using frequencies from a second satellite frequency band; and
communicating between the satellite and the radioterminal 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,wherein the first satellite frequency band comprises a first one of an L-band of frequencies and an S-band of frequencies and wherein the second satellite frequency band comprises a second one of the L-band of frequencies and the S-band of frequencies.

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.
