Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a video frame was not properly received by the wireless communication device. The wireless communication device may determine whether a reference frame is stored in a buffer of the wireless communication device based at least in part on determining that the video frame was not properly received. The wireless communication device may selectively transmit a negative acknowledgement (NACK) indication based at least in part on determining whether the reference frame is stored in the buffer. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to video telephony are provided. A device may proactively reduce the bitrate at which video is encoded at the beginning of a video call based on one or more radio metrics. Radio metrics used may include received signal strength indicator (RSSI), received signal received quality (RSRQ), received signal received power (RSRP), signal to noise ratio (SNR), power headroom (PHR), and block error rate (BER). The proactive reduction in bitrate is done prior to transmitting or receiving video data. The device may also request that a second device which is transmitting video do so at a reduced bitrate.

Abstract: This disclosure provides systems, methods, and apparatuses for adjusting an encoding timing or a decoding timing in a manner that minimizes disruption of ongoing uplink or downlink traffic. Some aspects more specifically relate to decoupling adjustment of the encoding timing and adjustment the decoding timing to enable independent adjustment of the encoding timing or the decoding timing. In some aspects, a user equipment (UE) may perform adjustment of the encoding timing, relative to an active time indicated by a discontinuous reception (DRX) configuration, at a time at which uplink traffic is absent. Additionally, or alternatively, the UE may perform adjustment of the decoding timing, relative to an active time indicated by a DRX configuration, at a time at which downlink traffic is absent. Accordingly, upon receiving a DRX configuration, the UE may wait until a period in which uplink traffic or downlink traffic is absent to perform a timing adjustment.

Abstract: Embodiments include methods performed by a processor of a receiving wireless device for rendering augmented reality content. The methods may include receiving real image data from a transmitting wireless device via a first data stream, and receiving augmented reality (AR) content from the transmitting wireless device via a second data stream that is an alt video stream, in which the AR content is for display with the real image data. Methods may further include displaying the AR content in conjunction with the real image data.
In some embodiments, the first data stream and the second data stream are Real-time Transport Protocol (RTP) streams.

Abstract: This disclosure provides systems, methods and apparatuses for enabling collision mitigation for a user equipment (UE) operating in a dual active mode. In some aspects, the UE may generate a communication for a first subscription in a first time window associated with a first priority for a time domain division pattern with a second subscription. The UE may transmit, using the first subscription, the communication in a second time window associated with a second priority for the time domain division pattern. For example, the second time window associated with the second priority may be a time window in which traffic for the first subscription is prioritized. In some aspects, the UE may select modified periodic intervals for transmissions of a communication to mitigate collisions associated with the time domain division pattern. For example, a transmission time of the periodic communication may be varied (or randomized) over time.
