Abstract

A wireless device includes a first wireless transceiver and a second wireless transceiver. The first wireless transceiver is configured to communicate via a first wireless network, and includes a first scheduler configured to schedule communication via the first wireless network. The second wireless transceiver is configured to communicate via a second wireless network. The second wireless transceiver includes a second scheduler. The second scheduler is configured to identify a resource allocated to the second wireless transceiver for a transaction via the second wireless network, to identify a portion of the resource used by the second wireless transceiver for the transaction, and to transfer information defining the portion to the first transceiver. The first scheduler is also configured to schedule, based on the information transferred by the second scheduler, the first transceiver to communicate via the first wireless network using the resource allocated to the second wireless transceiver for the transaction.

5. The wireless device of claim 1 , wherein the second scheduler is configured to transfer information comprising a resource use start time and one of a resource use end time and a resource use duration.

6. The wireless device of claim 1 , wherein the second scheduler is configured to transfer information comprising a resource idle start time and one of a resource idle end time and a resource idle duration.

7. The wireless device of claim 1 , wherein the second scheduler is configured to transfer information defining a plurality of different portions of the resource used by the second wireless transceiver for a given communication.

8. The wireless device of claim 1 , wherein the second scheduler is configured to transfer information identifying whether the portion is used by the second wireless transceiver for transmitting or receiving.

9. The wireless device of claim 1 , wherein the first scheduler is configured to configure the first wireless transceiver, based on the information, to access the first wireless network using a portion of the resource other than the defined portion of the resource.

10. A method, comprising:

scheduling, by a wireless device, a first communication via a first wireless network;

identifying, by the wireless device, a wireless resource allocated to the first communication;

identifying, by the wireless device, a portion of the wireless resource used by the first communication;

transferring information defining the identified portion of the resources to a scheduler in the wireless device that schedules a second communication, the information comprising a resource idle start time and one of a resource idle end time and a resource idle duration; and

scheduling, by the wireless device, based on the identified portion of the wireless resource, the second communication via a second wireless network using the wireless resource allocated to the first communication.

11. The method of claim 10 , further comprising transferring information defining the identified portion of the resources to a scheduler in the wireless device that schedules the second communication, the information comprising a resource allocation start time and one of a resource allocation end time and a resource allocation duration.

12. The method of claim 10 , further comprising transferring information defining the identified portion of the resources to a scheduler in the wireless device that schedules the second communication, the information comprising a resource use start time and one of a resource use end time and a resource use duration.

13. A method, comprising:

scheduling, by a wireless device, a first communication via a first wireless network:

identifying, by the wireless device, a wireless resource allocated to the first communication;

identifying, by the wireless device, a portion of the wireless resource used by the first communication, wherein identifying the portion comprises identifying a plurality of different portions of the resource used by the first communication, and a direction of wireless communication of each of the portions; and

scheduling, by the wireless device, based on the identified portion of the wireless resource, a second communication via a second wireless network using the wireless resource allocated to the first communication.

14. The method of claim 13 , further comprising transferring information defining the identified portion of the resources to a scheduler in the wireless device that schedules the second communication, the information comprising a resource idle start time and one of a resource idle end time and a resource idle duration.

15. The method of claim 10 , wherein the scheduling comprises

determining that the identified portion of the resource is used for receiving in the first communication; and

configuring the wireless device to receive via the second wireless network using the identified portion of the resources based on the determining.

16. The method of claim 10 , wherein the scheduling comprises configuring the wireless device to access the second wireless network using a portion of the resource other than the identified portion of the resources.

17. A coexistence scheduler, comprising:
