Abstract

System and techniques for radio spectrum sharing are described herein. A free radio spectrum block may be identified. An identification packet of the free radio spectrum block may be published. Here, the identification packet may include at least one of available spectrum, time, or area corresponding to the free radio spectrum block. An acknowledgement to the identification packet may be received. A provider of the free radio spectrum block may then be caused to cease radio communication on the available spectrum for the time and area specified in the identification packet.

First claim

What is claimed is:

1. A system for radio spectrum sharing, the system comprising:
a scheduler to:
identify a free radio spectrum block;
cause a provider of the free radio spectrum block to cease radio communication on available spectrum for a time and area specified in an identification packet;
determine a use for a portion of the free radio spectrum block when radio communications are ceased for the freed radio spectrum block: and
cause resumption of radio communication on the available spectrum in response to receipt of a threshold number of acknowledgements to a reclamation packet; and

a transceiver to:
publish the identification packet of the free radio spectrum block, the identification packet including at least one of the available spectrum, the time, or the area corresponding to the free radio spectrum block;
receive an acknowledgement to the identification packet;
publish the reclamation packet; and
receive acknowledgements to the reclamation packet.

2. The system of claim 1 , wherein the threshold number of acknowledgements are equal to a number of acknowledgements received to the identification packet.

3. The system of claim 1 , wherein, to receive the acknowledgment to the identification packet, the transceiver is to:
subscribe to a pending interest that matches the identification packet.

4. The system of claim 3 , wherein, to subscribe to the pending interest, the transceiver is to:
specify a number of expected acknowledgements, the number of expected acknowledgments cause a pending interest controller to keep the pending interest for at least as many acknowledgments as specified.

5. The system of claim 1 , wherein, to identify the free radio spectrum block, the scheduler is to:
obtain a parameter of the free radio spectrum block from a licensed shared access (LSA) incumbent; and
wherein the transceiver is to:
receive an interest packet from an LSA licensee, the interest packet including an indication of the parameter; and
wherein, to publish the identification packet, the transceiver is to transmit the identification packet to the LSA licensee.

6. The system of claim 5 , wherein, to transmit the identification packet to the LSA licensee, the transceiver is to:
encrypt the identification packet with a key for the LSA licensee, the key acquired prior to receipt of the interest packet.

7. The system of claim 5 , wherein the transceiver is to:
transmit a reclamation data packet in response to a reclamation interest packet maintained by the LSA licensee during a period of use of the free radio spectrum block by the LSA licensee; and
wherein the scheduler is to:
cause resumption of use of a radio spectrum of the free radio spectrum block in response to a reclamation acknowledgment by the LSA licensee.

8. The system of claim 1 , wherein, to identify the free radio spectrum block, the scheduler is to:
obtain a parameter of the free radio spectrum block from an incumbent; and
wherein the transceiver is to:
receive an interest packet from a general authorized access (GAA) device, the interest packet including an indication of the parameter.

9. The system of claim 8 , wherein, to identify the free radio spectrum block, the transceiver is to:
receive a second interest packet from a priority access licensee (PAL), the interest packet including an indication of the parameter.

10. The system of claim 9 wherein the scheduler is to:
receive a registration request from the PAL; and
register the PAL.

11. A method for radio spectrum sharing, the method comprising:
identifying, via a scheduler, a free radio spectrum block;
publishing, via a transceiver, an identification packet of the free radio spectrum block, the identification packet including at least one of available spectrum, time, or area corresponding to the free radio spectrum block;
receiving, via the transceiver, an acknowledgement to the identification packet;
causing a provider of the free radio spectrum block to cease radio communication on the available spectrum for the time arid area specified in the identification packet;
determining a use for a portion of the free radio spectrum block;
publishing a reclamation packet;
receiving acknowledgements to the reclamation packet; and
causing resumption of radio communication on the available spectrum in response to receiving, a threshold number of acknowledgements to the reclamation packet.

12. The method of claim 11 , wherein identifying the free radio spectrum block includes:
obtaining a parameter of the free radio spectrum block from an incumbent; and
receiving an interest packet from a general authorized access (GAA) device, the interest packet including an indication of the parameter.

13. The method of claim 12 , wherein identifying the free radio spectrum block includes:
receiving a second interest packet from a priority access licensee (PAL), the interest packet including an indication of the parameter.

14. The method of claim 11 , wherein receiving the acknowledgment to the identification packet includes subscribing to a pending interest that matches the identification packet.

15. The method of claim 14 , wherein subscribing to the pending interest includes specifying a number of expected acknowledgements, the number of expected acknowledgments causing a pending interest controller to keep the pending interest for at least as many acknowledgments as specified.

16. At least one non-transitory machine readable medium including instructions for radio spectrum sharing, the instructions, when executed by processing circuitry, cause the processing circuitry to perform operations comprising:
identifying a free radio spectrum block;
publishing an identification packet of the free radio spectrum block, the identification packet including at least one of available spectrum, time, or area corresponding to the free radio spectrum block;
receiving an acknowledgement to the identification packet;
causing a provider of the free radio spectrum block to cease radio communication on the available spectrum for the time and area specified in the identification packet;
determining a use for a portion of the free radio spectrum block;
publishing a reclamation packet;
receiving acknowledgements to the reclamation packet; and
causing resumption of radio communication on the available spectrum in response to receiving a threshold number of acknowledgements to the reclamation packet.

17. The at least one non-transitory machine readable medium of claim 16 , wherein the threshold number of acknowledgements are equal to a number of acknowledgements received to the identification packet.

18. The at least one non-transitory machine readable medium of claim 16 , wherein receiving the acknowledgment to the identification packet includes subscribing to a pending interest that matches the identification packet.

19. The at least one non-transitory machine readable medium of claim 18 , wherein subscribing to the pending interest includes specifying a number of expected acknowledgements, the number of expected acknowledgments causing a pending interest controller to keep the pending interest for at least as many acknowledgments as specified.

20. The at least one non-transitory machine readable medium of claim 16 , wherein identifying the free radio spectrum block includes:
obtaining a parameter of the free radio spectrum block from a licensed shared access (ISA) incumbent; and
receiving an interest packet from an LSA licensee, the interest packet including an ind
