Abstract: A UE may obtain a first set of audio packets based on a configured periodic cycle with a network node. The UE may transmit, for the network node, a first set of uplink (UL) transmissions associated with the first set of audio packets based on a first periodic time interval. The first periodic time interval may be different than the configured periodic cycle. The first periodic time interval may be based on a first multiplier and the configured periodic cycle. The UE may be a transmitter UE. The network node may receive, from the transmitter UE, the first set of UL transmissions associated with the first set of audio packets based on the first periodic time interval. The network node may output, for a receiver UE, the first set of UL transmissions associated with the first set of audio packets.

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.

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: Various protocols have been defined that computing devices can use to establish a real-time communication session. These protocols can describe techniques by which the computing devices can negotiate the parameters to use in the communication session, so that each device transmits media that the other device or devices are able to accept. Feedback mechanisms aid in correcting issues with media streams. Techniques can be used to determine the feedback mechanisms supported by a computing device on a session, when the computing device indicates that the computing device supports feedback, but does not specify the types of feedback that the computing device supports. These techniques can include sending a message that requires a response. When the response is received, the sending device can determine a feedback type supported by the receiving device.
