Abstract

Aspects of the present disclosure provide a method for wireless communications that may be performed (e.g., by a user equipment) for location information reporting. The method generally includes determining one or more properties of the UE and adjusting one or more parameters of location information reporting based on the determined one or more properties.

identifying, based at least in part on the determined one or more properties of the UE, one or more parameters for determining the location of the UE, wherein identifying one or more parameters for determining the location of the UE comprises adjusting a number of times the UE can request location information using the WWAN data services based on the determined data usage threshold;

determining the location of the UE based on data from the selected one or more location information devices, wherein the data is generated based, at least in part, on the one or more parameters; and

reporting the determined location of the UE.

2. The method of claim 1, wherein the determining one or more properties of the UE comprises determining at least one of a battery level or charging state.

3. The method of claim 2, wherein:

the determining at least one of a battery level or charging state comprises determining that the battery level exceeds a threshold value or determining that a battery is charging; and

selecting the one or more location information devices comprises enabling a satellite positioning system (SPS) receiver.

4. The method of claim 1, wherein the determining one or more properties of the UE comprises determining a frequency of requests for location information.

5. The method of claim 1, wherein the determining one or more properties of the UE comprises determining the UE is currently at a previously known location.

6. The method of claim 1, wherein the one or more parameters comprises an acceptable level of location accuracy.

7. The method of claim 1, wherein the one or more parameters comprises a frequency with which the UE can request location information from the selected one or more location information devices.

8. The method of claim 1, wherein the one or more parameters comprises a maximum number of requests for location information the UE can make during a service period.

9. An apparatus for wireless communications by a user equipment (UE), comprising:

at least one processor configured to;

determine one or more properties of the UE, wherein the one or more properties include at least power state, last known location information, and a data usage threshold;

select, based at least in part on the determined one or more properties of the UE, one or more location information devices of a plurality of location information devices of the UE to activate for determining a location of the UE, wherein selecting the one or more location information devices comprises selecting wireless wide area network (WWAN) data services to use for determining the location of the UE;

identify, based at least in part on the determined one or more properties of the UE, one or more parameters for determining the location of the UE, wherein identifying one or more parameters for determining the location of the UE comprises adjusting a number of times the UE can request location information using the WWAN data services based on the determined data usage threshold;

determine the location of the UE based on data from the selected one or more location information devices, wherein the data is generated based, at least in part, on the one or more parameters; and

report the determined location of the UE; and

a memory coupled to the at least one processor.

10. The apparatus of claim 9, wherein the at least one processor is further configured to determine at least one of a battery level or charging state.

11. The apparatus of claim 10, wherein the at least one processor is further configured to:

determine that the battery level exceeds a threshold value or determining that a battery is charging; and

select the one or more location information devices by enabling a satellite positioning system (SPS) receiver.

12. The apparatus of claim 9, wherein the at least one processor is further configured to determine a frequency of requests for location information.

13. The apparatus of claim 9, wherein the at least one processor is further configured to determine the UE is currently at a previously known location.

14. The apparatus of claim 9, wherein the one or more parameters comprises an acceptable level of location accuracy.

15. The apparatus of claim 9, wherein the one or more parameters comprises a frequency with which the UE can request location information from the selected one or more location information devices.

16. The apparatus of claim 9, wherein the one or more parameters comprises a maximum number of requests for location information the UE can make during a service period.

17. An apparatus for wireless communications by a user equipment (UE), comprising:

means for determining one or more properties of the UE, wherein the one or more properties include at least power state, last known location information, and a data usage threshold;

means for selecting, based at least in part on the determined one or more properties of the UE, one or more location information devices of a plurality of location information devices of the UE to activate for determining a location of the UE, wherein the means for selecting the one or more location information devices comprises means for selecting wireless wide area network (WWAN) data services to use for determining the location of the UE;
