Abstract

Methods, devices and systems for dynamic scheduling of Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Bluetooth can deduce information on the LTE DL/UL activity based at least in part on the LTE frame structure, LTE decision point or the LTE subframe boundary time. In some examples, Bluetooth scheduler can dynamically change the timing of the scheduling algorithm such that it may utilize the knowledge of LTE traffic and may at least partially avoid interference or evaluate the interference level.

First claim

What is claimed is:

1. A method for dynamic Bluetooth scheduling, the method comprising the steps of:
determining, by a Bluetooth device or interface, flexibility of a Bluetooth signal;
receiving, by the Bluetooth device or interface, from a Long Term Evolution (LTE) device or interface, LTE information comprising information relating to a LTE frame structure and an LTE decision point, wherein the LTE frame structure is semi-static and the information relating to the LTE frame structure is conveyed over a Non Real Time (NRT) coexistence interface, and wherein the LTE decision point comprises a notification point for the LTE device to convey one or more messages responsive to a traffic state change; and
scheduling, based at least in part on the LTE information, the Bluetooth signal.

2. The method of claim 1 , wherein the LTE information further comprises information relating to a LTE inactivity duration.

3. The method of claim 1 , wherein the Bluetooth device or interface and the LTE device or interface communicate via a Mobile Wireless Standards (MWS) Coex transport interface.

4. The method of claim 1 , wherein the LTE information comprises Real Time (RT) and Non Real Time (NRT) messages.

5. The method of claim 1 , wherein the LTE decision point is fixed relative to a subframe boundary.

6. A wireless communication device comprising:
a Bluetooth device or interface for sending and receiving one or more Bluetooth signals; and
a Long Term Evolution (LTE) device or interface for sending and receiving one or more LTE signals;
the Bluetooth device or interface configured to receive, from the LTE device or interface, LTE information comprising information relating to a LTE frame structure and an LTE decision point, wherein the LTE frame structure is semi-static and the information relating to the LTE frame structure is conveyed over a Non Real Time (NRT) coexistence interface, and wherein the LTE decision point comprises a notification point for the LTE device to convey one or more messages responsive to a traffic state change; and

to schedule the one or more Bluetooth signals based at least in part on the LTE information.

7. The wireless communication device of claim 6 , wherein the LTE information further comprises information relating to a LTE inactivity duration.

8. The wireless communication device of claim 6 , wherein the Bluetooth device or interface and the LTE device or interface communicate via a Mobile Wireless Standards (MWS) Coex transport interface.

9. The wireless communication device of claim 6 , wherein the LTE information comprises Real Time (RT) and Non Real Time (NRT) messages.

10. The wireless communication device of claim 6 , wherein the LTE decision point is fixed relative to a subframe boundary.

11. A non-transitory computer readable medium including instructions stored thereon, which when executed by one or more processor(s) of a wireless communication device, cause the device to perform operations of:
determining, by a Bluetooth device or interface in the wireless communication device, flexibility of a Bluetooth signal;
receiving, by the Bluetooth device or interface, from a Long Term Evolution (LTE) device or interface in the wireless communication device, LTE information comprising information relating to a LTE frame structure and an LTE decision point, wherein the LTE frame structure is semi-static and the information relating to the LTE frame structure is conveyed over a Non Real Time (NRT) coexistence interface, and wherein the LTE decision point comprises a notification point for the LTE device to convey one or more messages responsive to a traffic state change; and
scheduling, based at least in part on the LTE information, the Bluetooth signal.

12. The computer readable medium of claim 11 , wherein the LTE information further comprises information relating to a LTE inactivity duration.

13. The computer readable medium of claim 11 , wherein the Bluetooth device or interface and the LTE device or interface communicate via a Mobile Wireless Standards (MWS) Coex transport interface.

14. The computer readable medium of claim 11 , wherein the LTE information comprises Real Time (RT) and Non Real Time (NRT) messages.

15. The computer readable medium of claim 11 , wherein the LTE decision point is fixed relative to a subframe boundary.
