Abstract

Aspects presented herein may improve the performance of mobile/computer applications. Aspects presented herein may enable mobile/computer applications to differentiate entities that are associated with UEs or entities running the navigations applications, thereby enabling the mobile/computer applications (or their associated servers) to have a more accurate understanding of the conditions surrounding the UEs and their users. In one aspect, a network node obtains first information including at least one feature associated with a plurality of devices. The network node selects a first subset of the plurality of devices for a measurement based on the at least one feature associated with the plurality of devices (or the network node may exclude a second subset of the plurality of devices from the measurement).

First claim

What is claimed is:

1. An apparatus for wireless communication at a network node, comprising:
at least one memory; and
at least one processor coupled to the at least one memory and, based at least in part on information stored in the at least one memory, the at least one processor is configured to:
obtain first information including at least one feature associated with a plurality of devices;
classify, based on the first information, a first subset of devices in the plurality of devices as a cluster of user equipments (UEs) collocated with each other; and
perform a traffic prediction based on treating the cluster of UEs as one UE.

2. The apparatus of claim 1 , wherein the network node is a user equipment (UE), a component of the UE, a base station, a component of the base station, a network entity, or a location server.

3. The apparatus of claim 1 , wherein to obtain the first information, the at least one processor is configured to obtain the first information from the plurality of devices, at least one base station or a component of the at least one base station, at least one road side unit RSU), or a combination thereof.

4. The apparatus of claim 1 , wherein the traffic prediction is associated with at least one of: a navigation application, a position location application, an advertisement application, a messaging application, a location server, a crowd-sourcing server, or a venue statistic calculation.

5. The apparatus of claim 1 , wherein the at least one feature corresponds to an approximate location of the plurality of devices, a relative location of the plurality of devices, a location of the plurality of devices on corresponding travel ways, a number of the plurality of devices, Doppler information associated with the plurality of devices, an orientation of the plurality of devices, a speed of the plurality of devices, or a combination thereof.

6. The apparatus of claim 1 , wherein the at least one feature corresponds to a position of the plurality of devices, and wherein the position of the plurality of devices is based on vehicle-to-everything (V2X) positioning, ultra-wideband (UWB) positioning, Wi-Fi positioning, control plane positioning, or a combination thereof.

7. The apparatus of claim 1 , wherein the at least one feature corresponds to an acceleration of each of the plurality of devices.

8. The apparatus of claim 1 , wherein the at least one feature corresponds to sound captured by the plurality of devices.

9. The apparatus of claim 1 , wherein to classify, based on the first information, the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other, the at least one processor is configured to:
receive sounds recorded by the first subset of devices in the plurality of devices; and
classify the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other based on the sounds recorded by the first subset of devices being similar.

10. The apparatus of claim 9 , wherein the sounds include hum of tires, engine noise, air turbulence, passengers talking, music, or a combination thereof.

11. The apparatus of claim 1 , wherein the at least one processor is further configured to:
instruct the first subset of devices to perform at least one measurement with one or more other devices to verify an accuracy of the first information.

12. The apparatus of claim 1 , wherein the at least one processor is further configured to:
augment the first information with data received from at least one other platform, wherein classification of the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other is further based on the data.

13. The apparatus of claim 1 , wherein the at least one processor is further configured to:
verify or confirm an accuracy of classification of the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other based on radio frequency (RF) sensing.

14. The apparatus of claim 1 , wherein to classify, based on the first information, the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other, the at least one processor is configured to:
exclude, based on the first information, a second subset of devices in the plurality of devices that is classified as a pedestrian UE, wherein the pedestrian UE correspond to a UE being held by, or co-located with, a pedestrian.

15. The apparatus of claim 1 , wherein the at least one feature corresponds to an identification of the plurality of devices or one or more objects associated with the plurality of devices.

16. The apparatus of claim 15 , wherein the identification of the plurality of devices or the one or more objects associated with the plurality of devices is based on using at least one sensor associated with an advanced driver assistance systems (ADAS).

17. A method of wireless communication at a network node, comprising:
obtaining first information including at least one feature associated with a plurality of devices;
classifying, based on the first information, a first subset of devices in the plurality of devices as a cluster of user equipments (UEs) collocated with each other; and
performing a traffic prediction based on treating the cluster of UEs as one UE.

18. The method of claim 17 , wherein obtaining the first information comprises obtaining the first information from the plurality of devices, at least one base station or a component of the at least one base station, at least one road side unit (RSU), or a combination thereof.

19. The method of claim 17 , wherein the at least one feature corresponds to an approximate location of the plurality of devices, a relative location of the plurality of devices, a location of the plurality of devices on corresponding travel ways, a number of the plurality of devices, Doppler information associated with the plurality of devices, an orientation of the plurality of devices, a speed of the plurality of devices, or a combination thereof.

20. The method of claim 17 , wherein the at least one feature corresponds to a position of the plurality of devices, and wherein the position of the plurality of devices is based on vehicle-to-everything (V2X) positioning, ultra-wideband (UWB) positioning, Wi-Fi positioning, control plane positioning, or a combination thereof.

21. The method of claim 17 , wherein the at least one feature corresponds to an acceleration of each of the plurality of devices or to sound captured by the plurality of devices.

22. The method of claim 17 , wherein classifying, based on the first information, the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other comprises:
receiving sounds recorded by the first subset of devices in the plurality of devices; and
classifying the first subset of devices in the plurality of devices as the cluster of UEs collocated with each other based on the sounds recorded by the first subset of devices being similar.

23. The method of claim 22 , the sounds include hum of tires, engine noise, air turbulence, passengers talking, music, or a combination thereof.
