Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may start a timer for obtaining quality of experience (QoE) measurements. The UE may obtain the QoE measurements until the timer expires. The UE may transmit information indicating the QoE measurements. Numerous other aspects are described.

First claim

What is claimed is:

1 . A user equipment (UE) for wireless communication, comprising:
a memory; and one or more processors, coupled to the memory, configured to:
start a timer for obtaining quality of experience (QoE) measurements;
obtain the QoE measurements until the timer expires; and
transmit information indicating the QoE measurements.

2 . The UE of claim 1 , wherein the timer runs in an application layer.

3 . The UE of claim 2 , wherein the timer is started based at least in part on the application layer receiving, from a lower layer, one or more of a pause indication, a transmission failure indication, a QoE configuration, a resume measurement indication, or a start measurement indication.

4 . The UE of claim 3 , wherein the one or more processors are configured to receive, from an access stratum layer, timer configuration information to configure the timer per one or more of a service type, a QoE configuration, or a network slice.

5 . The UE of claim 1 , wherein the timer runs in an access stratum (AS) layer.

6 . The UE of claim 5 , wherein the timer is started based at least in part on receiving a pause indication, a resume measurement indication, a start measurement indication, or a QoE configuration.

7 . The UE of claim 5 , wherein the timer is started based at least in part on a transmission failure at the AS layer or entering an idle or inactive state.

8 . The UE of claim 5 , wherein the one or more processors are configured to provide, to an application layer, an indication to stop measurements or an indication that the timer expired.

9 . The UE of claim 5 , wherein the one or more processors are configured to receive, from a base station, timer configuration information that is configured per one or more of a service type, a QoE configuration, or a network slice.

10 . The UE of claim 1 , wherein the one or more processors are configured to release a QoE configuration after the timer expires.

11 . The UE of claim 1 , wherein the one or more processors are configured to release a QoE configuration after a separate release timer expires.

12 . The UE of claim 1 , wherein the one or more processors are configured to:
store one or more QoE measurements of the QoE measurements that are obtained within a time window; and discard any QoE measurements of the QoE measurements that are obtained outside the time window.

13 . The UE of claim 12 , wherein the time window is configured per one or more of a service type, a QoE configuration, or a network slice.

14 . The UE of claim 1 , wherein the one or more processors are configured to stop the obtaining if a storage size of QoE measurements satisfies a storage size threshold.

15 . The UE of claim 1 , wherein the one or more processors are configured to:
store one or more QoE measurements of the QoE measurements that are obtained within a storage size window or a storage queue window; and discard any QoE measurements of the QoE measurements that are obtained outside the storage size window or the storage queue window.

16 . The UE of claim 1 , wherein the one or more processors are configured to store one or more QoE measurements of the QoE measurements that are for one or more of a defined time duration or a defined location.

17 . The UE of claim 1 , wherein the one or more processors are configured to overwrite stored QoE measurements with the QoE measurements if a QoE measurement storage is full.

18 . The UE of claim 17 , wherein the one or more processors are configured to overwrite the stored QoE measurements based at least in part on a result of comparing a service type priority of the stored QoE measurements and a service type priority of the QoE measurements.

19 . The UE of claim 17 , where the one or more processors are configured to overwrite the stored QoE measurements based at least in part on a result of comparing a priority of a time duration or a location of the stored QoE measurements and a priority of a time duration or a location of the QoE measurements.

20 . The UE of claim 17 , where the one or more processors are configured to overwrite the stored QoE measurements based at least in part on receiving an indication from a base station.

21 . A base station for wireless communication, comprising:
a memory; and one or more processors, coupled to the memory, configured to:
transmit, to a user equipment (UE), timer configuration information for measuring a quality of experience (QoE) using a timer; and
receive QoE information indicating QoE measurements obtained by the UE before expiration of the timer.

22 . The base station of claim 21 , wherein the one or more processors are configured to transmit a QoE measurement pause command based at least in part on the QoE information.

23 . The base station of claim 21 , wherein the one or more processors are configured to transmit updated timer configuration information based at least in part on the QoE information.

24 . The base station of claim 21 , wherein the timer runs in an application layer.

25 . The base station of claim 21 , wherein the timer runs in an access stratum layer.

26 . The base station of claim 21 , wherein the timer configuration information configures the timer per one or more of a service type, a QoE configuration, or a network slice.

27 . The base station of claim 21 , wherein the timer configuration information includes configuration information for one or more of a storage size, a time window, a storage size window, or a storage queue window.

28 . The base station of claim 27 , wherein the one or more of the storage size, the time window, the storage size window, or the storage queue window is configured per one or more of a service type, a QoE configuration, or a network slice.

29 . The base station of claim 21 , wherein the timer configuration information includes priority information for overwriting stored QoE measurements with QoE measurements based at least in part on comparing a priority of a time duration or a location of the stored QoE measurements and a priority of a time duration or a location of the QoE measurements.

30 . The base station of claim 21 , wherein the timer configuration information indicates whether to overwrite stored QoE measurements with QoE measurements.

31 . A method of wireless communication performed by a user equipment (UE), comprising:
starting a timer for obtaining new quality of experience (QoE) measurements; obtaining the new QoE measurements until the timer expires; and transmitting information indicating the new QoE measurements.

32 . A method of wireless communication performed by a base station, comprising:
transmitting, to a user equipment (UE), timer configuration information for measuring a quality of experience (QoE) using a timer; and receiving QoE information indicating QoE measurements obtained by the UE before expiration of the timer.
