Abstract: In an example, a method of processing data includes, in a video telephony session between a local device and a remote device, where the video telephony session includes at least one video connection between the local device and the remote device, identifying, by the local device, degraded playback of video data at the remote device. The method also includes, in response to identifying the degraded playback, terminating, by the local device, a video connection of the at least one video connection.

Abstract: A method of wireless communication, performed by a user equipment (UE), includes: participating in a first communication session associated with a first subscriber identity module (SIM) and participating in a second communication session associated with a second SIM, wherein the UE comprises the first SIM and the second SIM; applying a higher priority of access to radio frequency (RF) resources of the UE to transmissions of the first communication session over transmissions of the second communication session; detecting a first type of packet within a data queue, the first type of packet being associated with the first communication session; in response to the detecting of the first type of packet, changing the higher priority of access to the transmissions of the second communication session; and returning the higher priority of access to the transmissions of the first communication session subsequent to the first type of packet being transmitted.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may calculate one or more parameters associated with a quality of communications between the UE and a base station. The UE may determine a bitrate for performing the communications based on the one or more calculated parameters prior to receiving a bitrate recommendation from the base station, and the UE may transmit, prior to receiving the bitrate recommendation from the base station, a request to perform the communications in accordance with the determined bitrate. The base station may determine whether to accept the requested bitrate, and perform the communications with the UE in accordance with the determination.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may dynamically indicate a resolution change to a display of the UE during a video call. For example, a first UE may communicate a configuration message with a second UE to establish a video call between the first UE and the second UE and indicate a first value for a resolution of a display of the first UE. During the video call, the first UE may identify a change to the resolution of the display and may transmit a message to the second UE that indicates the change to the resolution. In response to receiving the message, the second UE may encode one or more packets including video information for the video call according to a second value for the resolution and transmit the one or more packets to the first UE.

Abstract: Methods, systems, and devices for video frame rendering are described. A device, such as a user equipment (UE) may receive a set of video packets over a video connection (e.g., a video telephone service) and generate a set of video frames based on the set of video packets. The device may determine to render a video frame of the set of video frames based on a frame type of the video frame or a rendering criteria including a video quality of the video frame, or both. In some examples, the frame type may include a perfect frame or a corrupted frame. The device may render the video frame of the set of video frames based on the frame type of the video frame or the video frame satisfying the rendering criteria, or both, and output the rendered video frame for display.

Abstract: Disclosed are techniques for communication. In an aspect, a communications devices communicates, from an upper communication layer (e.g., application layer) to a lower communication layer (e.g., transport layer), indication(s) to prioritize certain frames (e.g., recovery frames and/or feedback frames) over other frames (e.g., Inter frames) associated with the same QCI bearer for a video streaming session. The lower communication layer may place the prioritized frames ahead of the non-prioritized frames in a lower layer transmission buffer based on the indication. The communications device may transmit one or more packets carrying the first set of frames before one or more packets carrying the second set of frames based on the first set of frames being placed ahead of the second set of frames in the lower layer transmission buffer.

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value, to determine a receive time of a first audio packet of a talk spurt, to determine a target delay value associated with a de-jitter buffer based on the arrival delay value and the receive time of the first audio packet. The apparatus also includes a decoder timing control circuitry configured, in response to detecting the first audio being dequeued from the de-jitter buffer, to cause a decoder to start decoding of the first audio packet.

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value based on previously received audio packets, to identify a receive time of a first audio packet of a talk spurt, to determine an offset value of the first audio packet based on the receive time and the arrival delay value, and to adjust a target delay value associated with a de-jitter buffer based on the offset value. The apparatus also includes a de-jitter buffer configured to buffer the first audio packet based on the adjusted target delay value.
