Abstract

Methods and systems are provided for dynamically disabling beamforming functionality of a first frequency band. The first frequency band is determined to have beamforming enabled. The user device is detected as being connected to the first frequency band for access to a wireless telecommunications network. A first fading channel measurement of the first frequency band is determined to be above a threshold. In response to determining that the first fading channel measurement is above the threshold, beamforming of the first frequency band is dynamically disabled.

Claims (44)

1. A system for dynamically disabling beamforming functionality of a first frequency band, the system comprising:

one or more nodes, each of the one or more nodes configured to wirelessly communicate with a user device in a geographic service area; and

one or more processors configured to perform operations comprising:

determine that the first frequency band has beamforming enabled;

detect that the user device is connected to the first frequency band for access to a wireless telecommunications network;

determine that a first fading channel measurement of the first frequency band is above a threshold; and

in response to determining that the first fading channel measurement is above the threshold, dynamically disable beamforming of the first frequency band.

2. The system of claim 1 , the operations further comprising:

dynamically connect the user device to a second frequency band that has a second fading channel measurement at or below the threshold.

3. The system of claim 1 , wherein the threshold is predetermined by an operator based on a location of the user device and historical data of other user devices.

4. The system of claim 1 , wherein the first fading channel measurement is measured using a model that depends on a time difference between input and output.

5. The system of claim 1 , wherein the first fading channel measurement is measured at a receiving end of the user device for a duration of time.

6. The system of claim 1 , wherein the first fading channel measurement is measured using a signal-to-noise ratio, a configuration of an antenna corresponding to the first frequency band, and a receiver type of the user device.

7. The system of claim 1 , the operations further comprising:

determine a second frequency band is beamforming enabled and has a second fading channel measurement at or below the threshold; and

dynamically connect the user device to the second frequency band for access to the wireless telecommunications network.

8. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method for dynamically disabling beamforming functionality of a first frequency band, the method comprising:

determining that the first frequency band and a second frequency band have beamforming enabled;

detecting that a user device is connected to the first frequency band for access to a wireless telecommunications network;

determining a first fading channel measurement of the first frequency band and that it is above a threshold;

determining a second fading channel measurement of the second frequency band and that it is at or below the threshold; and

in response to determining the first fading channel measurement and the second fading channel measurement, dynamically disabling beamforming of the first frequency band.

9. The media of claim 8 , further comprising:

dynamically connecting the user device to the second frequency band.

10. The media of claim 8 , wherein the first fading channel measurement and the second fading channel measurement comprise a filtration of noise prior to measurement.

11. The media of claim 8 , wherein the first fading channel measurement and the second fading channel measurement comprise a measurement of an average duration of how long a signal spends above the threshold.

12. The media of claim 8 , wherein the first fading channel measurement comprises a measurement of a rapidity of fading in beam power corresponding to the first frequency band.

13. The media of claim 8 , further comprising:

prior to determining the first fading channel measurement and the second fading channel measurement, detecting a second user device is connected to the first frequency band for access to the wireless telecommunications network; and

in response to dynamically disabling beamforming of the first frequency band, dynamically connecting the second user device to the second frequency band.

14. The media of claim 8 , wherein the threshold is predetermined based on a channel state information report.

15. The media of claim 14 , wherein the channel state information report is generated at regular intervals of time based on a predetermined reporting rate.

16. The media of claim 8 , wherein the first fading channel measurement included a measurement of fast fading.

17. The media of claim 8 , wherein the first fading channel measurement and the second fading channel measurement are determined based on a time varying channel model.

18. The media of claim 8 , wherein the first fading channel measurement is determined based on a Rayleigh fading model or a Rician fading model.

19. A method for dynamically disabling beamforming functionality of a first frequency band, the method comprising:

determining that the first frequency band has beamforming enabled;

determining that a user device:

(1) is connected to the first frequency band for access to a wireless telecommunications network, and

(2) is capable of connecting to a second frequency band having a higher frequency band than the first frequency band;

determining a first fading channel measurement of the first frequency band and that it is above a threshold; and

in response to determining the first fading channel measurement, dynamically disabling beamforming of the first frequency band.

20. The method of claim 19 , further comprising:

dynamically connecting the user device to the second frequency band for access to the wireless telecommunications network.
