Abstract

A method for wireless communication may comprise, for example, automatically determining first power settings for a first radio access technology (RAT) based on second power settings for a second RAT, and automatically applying the first power settings as power settings for the first RAT.

Claims

1. A method for wireless communication, the method comprising:

automatically determining first power settings for a first radio access technology (RAT) based on second power settings for a second RAT; and

automatically applying the first power settings as power settings for the first RAT, wherein

automatically determining the first power settings comprises determining a power setting function reflecting one or more differences between a first frequency band associated with the first RAT and a second frequency band associated with the second RAT, wherein the power setting function is based on at least one of a constant offset value, receiver sensitivity of the first RAT, receiver sensitivity of the second RAT, or a combination thereof.

2. The method of claim 1, wherein the power setting function is further based on at least one of interference at the first RAT, interference at the second RAT, or a combination thereof.

3. The method of claim 2, further comprising determining the interference at the first RAT based on at least one of measurements at a network listen module or measurements received from mobile entities.

4. The method of claim 1, wherein the constant offset value is a function of propagation profiles of the first and second frequency bands.

5. The method of claim 1, wherein automatically determining the first power settings comprises receiving the first power settings from a network node comprising an operations, administration, and maintenance (OAM) node.

6. The method of claim 1, further comprising adjusting power for the first RAT in response to a change in power for the second RAT.

7. The method of claim 1, further comprising automatically applying the first power settings as power settings for the second RAT.

8. An apparatus for wireless communication, comprising:

at least one processor configured to;

automatically determine first power settings for a first radio access technology (RAT) based on second power settings for a second RAT, and automatically apply the first power settings as power settings for the first RAT, wherein

the at least one processor is configured to automatically determine the first power settings by determining a power setting function reflecting one or more differences between a first frequency band associated with the first RAT and a second frequency band associated with the second RAT, wherein the power setting function is based on at least one of a constant offset value, receiver sensitivity of the first RAT, receiver sensitivity of the second RAT, or a combination thereof; and

a memory coupled to the at least one processor for storing data.

9. The apparatus of claim 8, wherein the power setting function is further based on at least one of interference at the first RAT, interference at the second RAT, or a combination thereof.

10. The apparatus of claim 9, wherein the at least one processor is further configured to determine the interference at the first RAT based on at least one of measurements at a network listen module or measurements received from mobile entities.

11. The apparatus of claim 8, wherein the constant offset value is a function of propagation profiles of the first and second frequency bands.

12. The apparatus of claim 8, wherein the at least one processor is configured to automatically determine the first power settings by receiving the first power settings from a network node comprising an operations, administration, and maintenance (OAM) node.

13. The apparatus of claim 8, wherein the at least one processor is further configured to adjust power for the first RAT in response to a change in power for the second RAT.

14. The apparatus of claim 8, wherein the at least one processor is further configured to automatically apply the first power settings as power settings for the second RAT.

15. An apparatus for wireless communication in a common radio node supporting multiple radio access technologies (RAT), comprising:

means for automatically determining first power settings for a first radio access technology (RAT) based on second power settings for a second RAT; and

means for automatically applying the first power settings as power settings for the first RAT, wherein

the means for automatically determining the first power settings comprises means for determining a power setting function reflecting one or more differences between a first frequency band associated with the first RAT and a second frequency band associated with the second RAT, wherein the power setting function is based on at least one of a constant offset value, receiver sensitivity of the first RAT, receiver sensitivity of the second RAT, or a combination thereof.

16. The apparatus of claim 15, wherein the power setting function is further based on at least one of interference at the first RAT, interference at the second RAT, or a combination thereof.

17. The apparatus of claim 16, wherein the means for determining the interference at the first RAT comprises means for determining the interference based on at least one of measurements at a network listen module or measurements received from mobile entities.

18. The apparatus of claim 15, wherein the constant offset value is a function of propagation profiles of the first and second frequency bands.

19. The apparatus of claim 15, wherein the means for automatically determining the first power settings comprises means for receiving the first power settings from a network node comprising an operations, administration, and maintenance (OAM) node.

20. The apparatus of claim 15, further comprising means for adjusting power for the first RAT in response to a change in power for the second RAT.

21. The apparatus of claim 15, further comprising means for automatically applying the first power settings as power settings for the second RAT.

22. A non-transitory computer-readable medium comprising code, which, when executed by at least one computer, causes the at least one computer to perform operations for wireless communication in a common radio node supporting multiple radio access technologies (RAT), the non-transitory computer-readable medium comprising:

code for automatically determining first power settings for a first radio access technology (RAT) based on second power settings for a second RAT; and

code for automatically applying the first power settings as power settings for the first RAT, wherein

the code for automatically determining the first power settings comprises code for determining a power setting function reflecting one or more differences between a first frequency band associated with the first RAT and a second frequency band associated with the second RAT, wherein the power setting function is based on at least one of a constant offset value, receiver sensitivity of the first RAT, receiver sensitivity of the second RAT, or a combination thereof.

23. The non-transitory computer-readable medium of claim 22, wherein the power setting function is further based on at least one of interference at the first RAT, interference at the second RAT, or a combination thereof.

24. The non-transitory computer-readable medium of claim 23, wherein the code for determining the interference at the first RAT comprises code for determining the interference based on at least one of measurements at a network listen module or measurements received from mobile entities.
