Abstract

A method of providing communications can be provided by at least one space-based and/or terrestrial component of a first system/operator transmitting/receiving information using spectrum allocated to a second system/operator at an aggregate interference level at a space-based component of the second system/operator that is less than or substantially equal to a predetermined threshold. Related other methods, systems, and radioterminals are also disclosed.

Claims

1. A radioterminal comprising:

a transmitter/receiver circuit configured to transmit/receive information to/from a terrestrial component of a first system/operator using spectrum that is allocated to a first space-based component of the first system/operator and using spectrum that is allocated to a second space-based component of a second system/operator.

2. A radioterminal according to claim 1 further comprising a baseband processor circuit configured to provide data to/from the transmitter/receiver circuit.

3. A radioterminal according to claim 2 wherein an aggregate interference controller is configured to adjust at least one parameter associated with the radioterminal to maintain an aggregate interference to be less than or substantially equal to a predetermined threshold.

4. A radioterminal according to claim 3 wherein the aggregate interference controller is configured to limit a number of radioterminals, to assign a data mode to a number of radioterminals and/or to assign a vocoder mode to a number of radioterminals.

5. A radioterminal according to claim 3 wherein the predetermined threshold comprises a level that is specified by the International Telecommunications Union.

6. A radioterminal according to claim 1 wherein the spectrum that is allocated to the first space-based component of the first system/operator and the spectrum that is allocated to the second space-based component of the second system/operator are non-overlapping in frequency ranges.

7. A radioterminal operating method, the method comprising:

transmitting/receiving information to/from a terrestrial component of a first system/operator using spectrum that is allocated to a first space-based component of the first system/operator and using spectrum that is allocated to a second space-based component of a second system/operator.

8. A method according to claim 7 further comprising providing data to/from the transmitting/receiving.

9. A method according to claim 8 further comprising adjusting at least one parameter associated with the radioterminal to maintain an aggregate interference to be less than or substantially equal to a predetermined threshold.

10. A method according to claim 9 wherein adjusting at least one parameter comprises limiting transmitting by the radioterminal, assigning a data mode to the radioterminal and/or assigning a vocoder mode to the radioterminal.

11. A radioterminal according to claim 9 wherein the predetermined threshold comprises a level that is specified by the International Telecommunications Union.

12. A radioterminal according to claim 7 wherein the spectrum that is allocated to the first space-based component of the first system/operator and the spectrum that is allocated to the second space-based component of the second system/operator are non-overlapping in frequency ranges.
