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.

Claims

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 LTE device or interface, LTE information comprising information relating to a LTE frame structure, a LTE Downlink or Uplink frame or subframe boundary, or a LTE decision point; and

scheduling, based at least in part on the LTE information, the Bluetooth signal.

2. The method of claim 1, wherein the LTE information comprises information relating to a LTE frame structure, a LTE Downlink or Uplink frame or subframe boundary, a LTE inactivity duration, and a LTE decision point.

a Bluetooth device or interface for sending and receiving one or more Bluetooth signals; and

a 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, a LTE Downlink or Uplink frame or subframe boundary, or a LTE decision point; and

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

9. The device of claim 8, wherein the LTE information comprises information relating to a LTE frame structure, a LTE Downlink or Uplink frame or subframe boundary, a LTE inactivity duration, and a LTE decision point.
