Quality of Experience Measurement

1 . A method comprising:

sending, by a master base station of a wireless device to a secondary base station of the wireless device, a request message comprising one or more available radio access network (RAN) visible quality-of-experience (QoE) metrics that can be collected by the secondary base station from the wireless device, wherein the wireless device is connected to the master base station and the secondary base station;

in response to the request message, receiving, by the master base station from the secondary base station, a message comprising at least one first RAN visible QoE metric that can be collected by the secondary base station from the wireless device; and

sending, by the master base station to the wireless device, a radio resource control (RRC) message, after receiving the message, to reconfigure the wireless device.

2 . The method of claim 1 , further comprising sending by the master base station to the secondary base station, a secondary node reconfiguration complete message.

3 . The method of claim 1 , wherein the request message comprises:

a secondary node modification request message;

a secondary node addition request message; or

a secondary node release request message.

4 . The method of claim 1 , wherein the message comprises:

a secondary node modification request acknowledge message;

a secondary node addition request acknowledge message;

a secondary node release request acknowledge message.

5 . The method of claim 1 , wherein the one or more available RAN visible QoE metric comprises at least one of:

buffer level;

playout delay for media startup;

an application layer buffer level;

an initial playout delay;

a round-trip time;

a jitter duration;

a correction duration;

an average throughput;

a device information;

rendered viewports;

a codec information;

representation switch events;

play list;

a media presentation description (MPD) information;

an interactivity summary; or

an interactivity event list.

6 . The method of claim 1 , wherein the secondary base station selects the at least one first RAN visible QoE metric based on the one or more available RAN visible QoE metrics.

7 . The method of claim 1 , wherein the request message further comprises a RAN visible QoE metrics query indication.

8 . The method of claim 1 , further comprising sending, by the master base station to the secondary base station, a message to configure dual connectivity for one or more services of the wireless device.

9 . The method of claim 8 , the one or more services are provided via radio resources of the master base station and the secondary base station.

10 . The method of claim 8 , the one or more services comprise at least one of:

a streaming service;

a multimedia telephony service for IMS (MTSI) service;

a virtual reality (VR) service;

an extended reality (XR) service;

a multimedia broadcast and multicast service (MBMS); or

a multicast broadcast service (MBS).

11 . The method of claim 8 , the one or more services are associated with a packet flow.

12 . The method of claim 11 , wherein the packet flow comprises at least one of:

a quality-of-service (QOS) flow;

a data radio bearer (DRB); or

a protocol data unit (PDU) session.

13 . A master base station of a wireless device, the master base station comprising one or more processors and memory storing instructions that, when executed by the one or more processors, cause the master base station at least to perform:

sending, to a secondary base station of the wireless device, a request message comprising one or more available radio access network (RAN) visible quality-of-experience (QoE) metrics that can be collected by the secondary base station from the wireless device, wherein the wireless device is connected to the master base station and the secondary base station;

in response to the request message, receiving, from the secondary base station, a message comprising at least one first RAN visible QoE metric that can be collected by the secondary base station from the wireless device; and

sending, to the wireless device, a radio resource control (RRC) message, after receiving the message, to reconfigure the wireless device.

14 . The master base station of claim 13 , further comprising sending by the master base station to the secondary base station, a secondary node reconfiguration complete message.

15 . The master base station of claim 13 , wherein the request message further comprises a RAN visible QoE metrics query indication.

16 . The master base station of claim 13 , further comprising sending, by the master base station to the secondary base station, a message to configure dual connectivity for one or more services of the wireless device.

17 . The master base station of claim 16 , the one or more services are provided via radio resources of the master base station and the secondary base station.

18 . The master base station of claim 16 , the one or more services are associated with a packet flow.

19 . The master base station of claim 18 , wherein the packet flow comprises at least one of:

a quality-of-service (QOS) flow;

a data radio bearer (DRB); or

a protocol data unit (PDU) session.

20 . A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a master base station of a wireless device, cause the master base station to perform:

sending, to a secondary base station of the wireless device, a request message comprising one or more available radio access network (RAN) visible quality-of-experience (QoE) metrics that can be collected by the secondary base station from the wireless device, wherein the wireless device is connected to the master base station and the secondary base station;

in response to the request message, receiving, from the secondary base station, a message comprising at least one first RAN visible QoE metric that can be collected by the secondary base station from the wireless device; and

sending, to the wireless device, a radio resource control (RRC) message, after receiving the message, to reconfigure the wireless device.
