Abstract

Aspects of the disclosure relate to power reduction measures that can be employed by wireless user equipment (UE) participating in an extended reality (XR) application. A wireless UE, while operating in a first power state, may receive, from an XR service provider, a plurality of packets corresponding to a video frame. The UE may reassemble and decode the received packets to reproduce the video frame. Once the UE determines it has received information sufficient to reproduce the video frame, the UE may enter a second power state, different from the first power state, for a predetermined amount of time. Other aspects, embodiments, and features are also claimed and described.

Claims29

Dependent claims

A method of wireless communication operable at a user equipment (UE), the method comprising:

receiving, while operating in a first power state, a first subset of packets of a plurality of packets, the first subset of packets corresponding to at least a first portion of a video frame of an initial state;
continuing to monitor for, based on the first subset of packets comprising less than a predetermined frame reproduction threshold of video data to reproduce the video frame in a reproduced state, an indication of transmission of a second subset of packets of the plurality of packets;
receiving the second subset of packets of the plurality of packets corresponding to at least a second portion of the video frame in the initial state, wherein the plurality of packets corresponding to the video frame in the initial state comprises the first subset of packets and the second subset of packets;
transmitting, based on the plurality of packets satisfying the predetermined frame reproduction threshold, a low-power state indicator indicating an intention of the UE to enter a second power state, different from the first power state;
and
outputting, while operating in the second power state, the video frame in the reproduced state.

A user equipment (UE), comprising:

a processor;
a transceiver;
and
a memory comprising instructions,
wherein the processor configured to execute the instructions and cause the user equipment to:
receive, via the transceiver while operating in a first power state, a first subset of packets of a plurality of packets, the first subset of packets corresponding to a video frame of an initial state;
continue to monitor for, based on the first subset of packets comprising less than a predetermined frame reproduction threshold of video data to reproduce the video frame in a reproduced state, an indication of transmission of a second subset of packets of the plurality of packets based on the determination that the first subset of packets comprises less than the predetermined frame reproduction threshold of video data to reproduce the video frame in the reproduced state;
receive, via the transceiver, the second subset of packets of the plurality of packets corresponding to at least a second portion of the video frame in the initial state, wherein the plurality of packets corresponding to the video frame in the initial state comprises the first subset of packets and the second subset of packets;
transmit, via the transceiver and based on the plurality of packets satisfying the predetermined frame reproduction threshold, a low-power state indicator signaling an intention of the UE to enter a second power state, different from the first power state;
and
output the video frame in the reproduced state while operating in the second power state.

8 more elements

A method of wireless communication operable at a user equipment (UE), the method comprising:

receiving, while operating in a first power state, a plurality of packets corresponding to a video frame of an initial state;
determining the plurality of packets satisfy a predetermined frame reproduction threshold, wherein the plurality of packets comprise information configured to reproduce the video frame in a reproduced state, wherein determining the plurality of packets satisfy the predetermined frame reproduction threshold comprises:
utilizing a first layer of the UE to determine that at least a subset of the plurality of packets comprises a threshold level of video data to generate the video frame in the reproduced state;
passing, from the first layer of the UE to a second layer of the UE, a message from the first layer of the UE to the second layer of the UE indicating that at least the subset of the plurality of packets comprises the threshold level of video data to generate the video frame in the reproduced state;
and
determining that the plurality of packets satisfies the predetermined frame reproduction threshold;
transmitting, based on determining the plurality of packets satisfy the predetermined frame reproduction threshold, a low-power state indicator indicating an intention of the UE to enter a second power state, different from the first power state;
and
outputting, while operating in the second power state, the video frame in the reproduced state.

6 more elements

A user equipment (UE), comprising:

a processor;
a transceiver;
and
a memory comprising instructions,
wherein the processor configured to execute the instructions and cause the user equipment to:
receive, via the transceiver while operating in a first power state, a plurality of packets corresponding to a video frame of an initial state;
determine the plurality of packets comprise a predetermined frame reproduction threshold of encoded video data that, when decoded, is configured to output the video frame in a reproduced state different from the initial state, wherein to determine the plurality of packets comprise the threshold amount of encoded video data, the processor is configured to cause the UE to pass a message from a first layer of the UE to a second layer of the UE indicating that the plurality of packets comprise the threshold amount of encoded video data to reproduce the video frame in the reproduced state;
transmit, via the transceiver and based on the determination that the plurality of packets satisfy the predetermined frame reproduction threshold, a low-power state indicator signaling an intention of the UE to enter a second power state, different from the first power state;
and
output the video frame in the reproduced state while operating in the second power state.
