Abstract

Methods and systems for auto coexistence priority selection for a SCO link are disclosed. Aspects of one method may include a first Bluetooth device communicating with a collocated WLAN device via a coexistence method. The first Bluetooth device, prior to executing a non-SCO task, which may comprise tasks that do not involve SCO packet transfer, may communicate low priority via the coexistence method if a Bluetooth SCO link is present between the first Bluetooth device and a second Bluetooth device, and if a current task being handled by the first Bluetooth device is a high priority task. If a SCO link is not present between the first and second Bluetooth devices, and if the current non-SCO task is a high priority task, the first Bluetooth device may communicate high priority via the coexistence method prior to executing the non-SCO task.

Claims

1. A device comprising:

at least one processor circuit configured to;

receive a task from a co-located first device, wherein the task is assigned a high priority by the first device and the task is performed without a point-to-point link;

determine whether the point-to-point link with a second device is currently present;

reassign the assigned high priority to a low priority if the point-to-point link is determined to be present;

communicate a low priority signal corresponding to the reassigned low priority with regard to the task via a coexistence method with a co-located third device if the point-to-point link is determined to be present; and

communicate a high priority signal corresponding to the assigned high priority with regard to the task via the coexistence method with the co-located third device if the point-to-point link is determined to be not present.

2. The device of claim 1, wherein the at least one processor circuit is further configured to:

after communicating the low priority signal, transitioning priority from the low priority to the high priority when the point-to-point link is determined to no longer be present.

3. The device of claim 1, wherein the at least one processor circuit is further configured to:

after communicating the high priority signal, transitioning priority from the high priority to the low priority when the point-to-point link is determined to be present.

4. The device of claim 1, wherein the at least one processor circuit is further configured to:

enable transmission of the co-located third device based at least on the communicated high or low priority signal of the task.

5. The device of claim 1, wherein the at least one processor circuit is further configured to:

initiate execution of the task.

6. The device of claim 1, wherein the task is associated with a first type of packets and the point-to-point link is associated with a second type of packets, the second type of packets being associated with a higher priority than the first type of packets.

7. A method comprising:

receiving, at a traffic arbitration device, a task from a first device co-located with the traffic arbitration device, wherein the task is assigned a high priority by the first device and the task is exclusive of transmitting a first type of packets;

determining, by the traffic arbitration device, a link with a second device for transmitting the first type of packets is currently present;

reassigning, by the traffic arbitration device, the assigned high priority of the task to a low priority when the link is determined to be present;

communicating, by the traffic arbitration device, a first signal corresponding to the reassigned low priority with regard to the task via a coexistence method with a co-located third device when the link is determined to be present; and

communicating, by the traffic arbitration device, a second signal corresponding to the assigned high priority with regard to the task via the coexistence method with the co-located third device when the link is determined to be not present.

8. The method of claim 7, wherein the first device transmits on a first channel having a first bandwidth and the co-located third device transmits on a second channel having a second bandwidth that is greater than the first bandwidth.

9. The method of claim 7, further comprising:

after communicating the first signal, transitioning priority of the task, by the traffic arbitration device, from the low priority to the high priority when the link is determined to no longer be present.

10. The method of claim 7, further comprising:

after communicating the second signal, transitioning priority of the task from the high priority to the low priority when the link is determined to be present.

11. The method of claim 7, further comprising enabling transmission of the co-located third device based at least on the communicated first or second signal associated with the task.

12. The method of claim 7, further comprising executing the task.

13. The method of claim 12, wherein the executing of the task comprises at least one of transmitting at least one packet in at least one frame or receiving at least one packet in at least one frame.

14. The method of claim 7, wherein the link comprises a point-to-point link and the task comprises a point to multi-point task.

15. A computer program product comprising instructions stored in a tangible non-transitory computer-readable storage medium, the instructions comprising:

instructions to receive, by a traffic arbitration device, a task from a first device co-located with the traffic arbitration device, wherein the task is assigned a high priority by the first device and the task is associated with transmitting a first type of packets;

determining, by the traffic arbitration device, whether a link with a second device for transmitting a second type of packets is currently present, wherein the second type of packets are associated with a higher priority than the first type of packets;

reassigning, by the traffic arbitration device, the assigned high priority of the task to a low priority if the link is determined to be present;

communicating, by the traffic arbitration device, a first signal corresponding to the reassigned low priority with regard to the task via a coexistence method with a co-located third device if the link is determined to be present; and

communicating, by the traffic arbitration device, a second signal corresponding to the assigned high priority with regard to the task via the coexistence method with the co-located third device if the link is determined to be not present.

16. The computer program product of claim 15, wherein the instructions further comprise:

instructions to, after communicating the first signal, transitioning priority of the task, by the traffic arbitration device, from the low priority to the high priority when the link is determined to no longer be present.

17. The computer program product of claim 15, wherein the instructions further comprise:

instructions to, after communicating the second signal, transitioning priority of the task from the high priority to the low priority when the link is determined to be present.

18. The computer program product of claim 15, wherein the instructions further comprise:

instructions to enable transmission of the co-located third device based at least on the communicated first or second signal of the task.

19. The computer program product of claim 15, wherein the instructions further comprise:

instructions to initiate execution of the task.

20. The computer program product of claim 15, wherein the link comprises a point-to-point link and the task comprises a point to multi-point task.
