Abstract

In some wireless communications systems, devices may support minimization of drive test (MDT) reporting, quality of service (QoS) reporting, and quality of experience (QoE) measurements. A user equipment (UE) and the serving base station may obtain measurements in accordance with a measurement configuration that indicates various triggering events or reporting adjustment factors associated with the measurements. The measurement configuration may indicate a triggering event such as the start of an application or service at the UE, and the UE may obtain MDT or QoE measurements based on identifying the application or service. Additionally, the serving base station may obtain MDT and QoE measurements based on identifying the application and service or a notification from the UE. The UE and the serving base station may identify reporting adjustment factors based on network slicing, area configurations and times of the day affecting the reporting interval and reporting amount for the measurement report.

First claim

What is claimed is:

1. A method for wireless communications at a user equipment (UE) comprising:
receiving, from an operations, administration, and maintenance (OAM) interface, a measurement configuration for performing quality of experience measurements to include in a quality of experience report;
identifying, from the measurement configuration, one or more triggering events which, upon occurrence, trigger the quality of experience measurements;
detecting a start of an application or a service at the UE, wherein the start of the application or service is one of the one or more triggering events;
obtaining the quality of experience measurements based at least in part on the start of the application or the service being one of the one or more triggering events;
transmitting, to a serving network device, an indication that the one or more triggering events has occurred;
obtaining minimization of drive test measurements based at least in part on the start of the application or service being one of the one or more triggering events, wherein obtaining the minimization of drive test measurements comprises obtaining one or more localization measurements as one or more received signal strength indicator measurements or round trip time measurements, and wherein the one or more localization measurements are associated with common location information, wireless local area network information, Bluetooth location information, sensor information, or any combination thereof; and
transmitting, to the serving network device, a report associated with the quality of experience measurements and the minimization of drive test measurements.

2. The method of claim 1 , further comprising:
identifying one or more application or service identifiers (IDs) associated with the application or service;
comparing the one or more application or service IDs to a list of IDs stored at the UE, wherein the list of IDs comprises IDs for applications or services associated with the one or more triggering events; and
determining that the one or more application or service IDs is contained in the list of IDs stored at the UE based at least in part on the comparing.

3. The method of claim 2 , further comprising:
generating the quality of experience report to include the one or more application or service IDs based at least in part on determining that the one or more application or service IDs is contained in the list of IDs stored at the UE.

4. The method of claim 2 , further comprising:
obtaining minimization of drive test measurements based at least in part on the start of the application or the service being one of the one or more triggering events, wherein obtaining the minimization of drive test measurements comprises obtaining radio resource management measurements based at least in part on determining that the one or more application or service IDs is contained in the list of IDs stored at the UE.

5. The method of claim 4 , wherein the radio resource management measurements comprise at least one of a reference signal received power measurement or a reference signal received quality measurement.

6. The method of claim 4 , wherein the radio resource management measurements comprise periodic measurements, event-triggered measurements, or any combination thereof.

7. The method of claim 1 , further comprising:
obtaining minimization of drive test measurements based at least in part on the start of the application or the service being one of the one or more triggering events, wherein obtaining the minimization of drive test measurements comprises obtaining one or more quality of service measurements based at least in part on the start of the application or the service triggering the obtaining of the one or more quality of service measurements.

8. The method of claim 7 , wherein the one or more quality of service measurements comprise one or more packet delay measurements or packet loss rate measurements.

9. The method of claim 1 , further comprising:
receiving, in the measurement configuration, an indication that the UE is to include one or more application or service identifiers in a report, wherein the one or more application or service identifiers prompt quality of service measurements by the serving network device.

10. The method of claim 9 , wherein the quality of service measurements by the serving network device comprise a data volume measurement, an internet protocol throughout measurement, a packet delay measurement, a packet loss measurement, or any combination thereof.

11. An apparatus for wireless communications, comprising:
one or more processors;
memory coupled with the one or more processors; and
instructions stored in the memory and executable by the one or more processors to cause the apparatus to:
receive, from an operations, administration, and maintenance (OAM) interface, a measurement configuration for performing quality of experience measurements to include in a quality of experience report;
identify, from the measurement configuration, one or more triggering events which, upon occurrence, trigger the quality of experience measurements;
detect a start of an application or a service at a user equipment (UE), wherein the start of the application or the service is one of the one or more triggering events;
obtain the quality of experience measurements based at least in part on the start of the application or the service being one of the one or more triggering events;
transmit, to a serving network device, an indication that the one or more triggering events has occurred;
obtain minimization of drive test measurements based at least in part on the start of the application or service being one of the one or more triggering events, wherein obtaining the minimization of drive test measurements comprises obtaining one or more localization measurements as one or more received signal strength indicator measurements or round trip time measurements, and wherein the one or more localization measurements are associated with common location information, wireless local area network information, Bluetooth location information, sensor information, or any combination thereof; and
transmit, to the serving network device, a report associated with the quality of experience measurements and the minimization of drive test measurements.

12. The apparatus of claim 11 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
identify one or more application or service identifiers (IDs) associated with the application or service;
compare the one or more application or service IDs to a list of IDs stored at the UE, wherein the list of IDs comprises IDs for applications or services associated with the one or more triggering events; and
determine that the one or more application or service IDs is contained in the list of IDs stored at the UE based at least in part on the comparing.

13. The apparatus of claim 11 , wherein the instructions are further executable by the one or more processors to cause the apparatus to:
obtain minimization of drive test measurements based at least in part on the start of the application or the service being one of the one or more triggering events, wherein, to obtain the minimization of drive test measurements, the instructions are executable by the processor to cause the apparatus to obtain one or more localization measurements based at least in part on the start of the application or service triggering the obtaining of the one or more localization measurements.

14. The apparatus of claim 12 , wherein the instructions are further executable by the one or more processors to
