Abstract

Methods, devices and systems for dynamic scheduling of Wi-Fi or Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Wi-Fi or Bluetooth can perform coexistence decisions including Wi-Fi and Bluetooth channel or Adaptive Frequency Hopping (AFH) selection based on modem calculated Rx or Tx indications and device geo location, maximum allowed transmit power per channel for Wi-Fi, and the LTE modem connection state.

First claim

What is claimed is:

1. A method comprising:
identifying, by a wireless communication device, a geographical location of the wireless communication device, based at least in part on a geographical map table corresponding to a mobile country code (MCC), wherein the geographical map table comprises geographical location information, received from an access point;
determining, by the wireless communication device, one or more long term evolution (LTE) operating band channels and one or more wireless fidelity (Wi-Fi) operating band channels, based at least in part on the geographical location information; and
selecting, by the wireless communication device, at least one first LTE operating band of the one or more LTE operating band channels as a Wi-Fi safe channel, based at least in part upon:
an estimated performance degradation of the wireless communication device, associated with an estimated interference level between at least one LTE signal and at least one Wi-Fi signal, on the at least one, first LTE operating band of the one or more LTE operating band channels, or
an estimate that the Wi-Fi safe channel will be switched, by the wireless communication device, to at least one second LTE operating band channel of the one or more LTE operating band channels.

2. The method of claim 1 , further comprising:
determining, by the wireless communication device, the estimated interference level between the at least one LTE signal and at least one Wi-Fi signal using a downlink error rate.

3. The method of claim 1 , wherein the selection is based at least in part upon dynamically scheduling, by the wireless communication device, transmissions of the at least one LTE signal or the at least one Wi-Fi signal, from a LTE radio or a Wi-Fi radio.

4. The method of claim 1 , further comprising:
receiving, by the wireless communication device, LTE information of the one or more LTE operating band channels, the LTE information comprising real time (RT) and non-real time (NRT) messages.

5. A wireless communication device comprising:
at least one memory comprising computer-executable instructions stored thereon; and
one or more processing elements to execute the computer-executable instructions to:
identify a geographical location of the wireless communication device, based at least in part on a geographical map table corresponding to a mobile country code (MCC), wherein the geographical map table comprises geographical location information, received from an access point;
determine one or more long term evolution (LTE) operating band channels and one or more wireless fidelity (Wi-Fi) operating band channels based at least in part on the geographical location; and
select at least one first LTE operating band channel of the one or more LTE operating band channels as a Wi-Fi safe channel, based at least in part upon:
an estimated performance degradation of the wireless communication device, associated with an estimated interference level between at least one LTE signal from the access point and at least one Wi-Fi signal, on the at least one first LTE operating band channel of the one or more LTE operating band channels, or
an estimate that the Wi-Fi safe channel will be switched, by the wireless communication device, to at least one second LTE operating band channel of the one or more LTE operating band channels.

6. The device of claim 5 , wherein a Wi-Fi device or a LTE device in the wireless communication device communicates via a mobile wireless standards (MWS) coexistence transport interface.

7. The device of claim 5 , wherein a Wi-Fi device or a LTE device in the wireless communication device communicates via a Wi-Fi host interface.

8. The device of claim 5 , wherein the one or more processing elements execute the computer-executable instructions that further cause the one or more processing elements to:
receive LTE information of the one or more LTE operating band channels, wherein the LTE information comprises real time (RT) and non-real time (NRT) messages.

9. A non-transitory computer readable storage device including instructions stored thereon, which when executed by one or more processor(s) of a wireless communication device, cause the wireless communication device to perform operations of:
identifying a geographical location of the wireless communication device, based at least in part on a geographical map table corresponding to a mobile country code (MCC), wherein the geographical map table comprises geographical location information, received from an access point;
determining one or more long term evolution (LTE) operating band channels and one or more wireless fidelity (Wi-Fi) operating band channels, based at least in part on the geographical location; and
selecting at least one first LTE operating band of the one or more LTE operating band channels as a Wi-Fi safe channel, based at least in part upon:
an estimated performance degradation of the wireless communication device, associated with an estimated interference level between at least one LTE signal from the access point and at least one Wi-Fi signal, on the at least one first LTE operating band channel, of the one or more LTE operating band channels, or
an estimate that the Wi-Fi safe channel will be switched, by the wireless communication device, to at least one second LTE operating band channel of the one or more LTE operating band channels.

10. The device of claim 9 , wherein a Wi-Fi device or LTE device in the wireless communication device communicates via a mobile wireless standards (MWS) coexistence transport interface.

11. The device of claim 9 , wherein a Wi-Fi device or LTE device in the wireless communication device communicates via a Wi-Fi host interface.

12. The device of claim 9 , wherein the one or more processor(s) of the wireless communication device execute the instructions to cause the wireless communication device to further perform operations of:
receiving LTE information of the one or more LTE operating band channels, wherein the LTE information comprises real time (RT) and non-real time (NRT) messages.

13. A method comprising:
identifying, by a wireless communication device, a geographical location of the wireless communication device, based at least in part on a geographical map table corresponding to a mobile country code (MCC), wherein the geographical map table comprises geographical location information, received from an access point;
determining, by the wireless communication device, one or more long term evolution (LTE) operating band channels, based at least in part on the geographical location; and
selecting, by the wireless communication device, at least one first LTE operating band channel of the one or more LTE operating band channels as a Bluetooth safe channel, based at least in part upon:
an estimated performance degradation of the wireless communication device, associated with an estimated interference level between at least one LTE signal from the access point and at least one Bluetooth signal, on the at least one first LTE operating band channel, of the one or more LTE operating band channels, or
an estimate that the Bluetooth safe channel will be switched, by the wireless communication device, to at least one second LTE operating band channel of the one or more LTE operating band channels.

14. The method of claim 13 , further comprising:
determining, by the wireless communication device, the estimated interference level between the at least one LTE signal from the access point and at least one Bluetooth signal using a downlink error rate.

15. The method of claim 13 , wherein the selecting is base
