Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a request to a network entity to establish a voice communication session with another UE that may be subscribed to a video service. The UE may transmit an indication of a video streaming parameter for the video service for streaming one-way video transmissions from the network entity to the UE for display during establishment of the voice communication session. The UE may transmit an indication of an updated video streaming parameter to the network entity to reduce the video quality for the video service. The network entity may reduce the video streaming quality for the one or more one-way video transmissions to the UE based on the updated video streaming parameter.

Abstract: In an embodiment, a user equipment (UE) groups a plurality of images. The UE displays a first image among the plurality of images, determines an object of interest within the first image and a desired level of zoom, and determines to lock onto the object of interest in association with one or more transitions between the plurality of images. The UE determines to transition to a second image among the plurality of images, and detects, based on the lock determination, the object of interest within the second image. The UE displays the second image by zooming-in upon the object of interest at a level of zoom that corresponds to the desired level of zoom.

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: A method and apparatus improve Voice over Internet Protocol (VOIP) call setup success rate and latency. The method provides for attempting a mobile originated packet switched call, by a user equipment (UE), across a packet switched network with a transmission control protocol (TCP) connection of the Internet Protocol multimedia subsystem (IMS) session. A silent redial of the mobile originated packet switched call is performed in response to a failure of the mobile originated packet switched call, via a circuit switched network. A keep alive message is transmitted over the packet switched network after the circuit switched network call, which allows reconnection to the packet switched network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a condition associated with a first radio access technology (RAT) is satisfied. The UE may select a cell, from a list of anchor cells associated with a second RAT and configured for dual-connectivity, for a connection based at least in part on the determination that the condition associated with the first RAT is satisfied. The UE may establish the connection with the selected cell. Numerous other aspects are provided.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE sets up an evolved packet system fallback (EPSFB) call procedure that is associated with network-configured inter-frequency measurements to be performed by the UE at a first inter-frequency measurement interval. The UE punctures some or all of the network-configured inter-frequency measurements during the EPSFB call procedure.

Abstract: Apparatus, methods, and computer-readable media for adjusting transmit power headroom for a secondary link while operating in an NSA mode are disclosed herein. An example method for wireless communication at a UE includes receiving a request to enter a multi-connectivity mode in which the UE is able to transmit data to a first base station via a first access link or to a second base station via a second access link. The example method also includes determining a first maximum uplink transmit power for transmissions using the first access link. Additionally, the example method includes determining a second maximum uplink transmit power for transmissions using the first access link based on uplink transmissions transmitted during an evaluation window. The example method also includes transmitting, via the first access link, at least one uplink transmission based on the second maximum uplink transmit power.

Abstract: Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving a request for a wireless connection from an application associated with one or more user equipment (UE) route selection policy (URSP) rules, attempting to establish the wireless connection for the application via a first subscriber identity module (SIM) according to one or more of the URSP rules associated with the application that are supported by the first SIM, and taking one or more actions to establish the wireless connection for the application via a second SIM if the attempt to establish the wireless connection for the application via the first SIM fails.
