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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, while the UE is in an active session using a first radio access technology (RAT) associated with a first subscription of the UE, a call request via the first RAT, wherein the call request is associated with a second subscription of the UE. The UE may determine that the call request is received from a serving cell that is associated with fallback from the first RAT to a second RAT for calls. The UE may reject the call request or transition the second subscription to a third RAT based at least in part on the determination that the call request is received via the serving cell that is associated with fallback from the first RAT to the second RAT for calls. Numerous other aspects are described.

Abstract: A configuration is disclosed to enable a UE to preempt SRVCC by triggering a handover to a Wi-Fi network. The apparatus determines whether a Wi-Fi cell is viable as a first target cell, from a plurality of target cells, serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus extends a TTT timer length based at least in part on the determination that the Wi-Fi cell is viable as the target cell serving the UE to continue the active transmission on the Wi-Fi cell. The apparatus initiates a handover to the Wi-Fi cell from the first network prior to the expiration of a TTT timer and prior to the first network initiating a handover to a second target cell, from the plurality of target cells, on a second network.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, via a first subscriber service, at least one protocol data unit (PDU) session. The UE may receive a first internet protocol (IP) address associated with the first subscriber service. The UE may register the first subscriber service with an IP multimedia subsystem (IMS) network using the first IP address. The UE may register a second subscriber service with the IMS network using a second IP address, wherein the second subscriber service uses the at least one PDU session of the first subscriber service. Numerous other aspects are described.

Abstract: In some aspects, a user equipment (UE) may communicate using a first radio access technology (RAT) for a first subscription of the UE, wherein the first RAT is selected from a group that includes a first cellular RAT associated with the first subscription, a second cellular RAT associated with a second subscription of the UE, and a wireless local area network (WLAN) RAT. The UE may communicate using a second RAT for the second subscription of the UE, wherein the second RAT is selected from the group that includes the first cellular RAT associated with the first subscription, the second cellular RAT associated with the second subscription of the UE, and the WLAN RAT. The UE may transition, based at least in part on a condition, a communication link carrying a protocol data unit (PDU) session from the second subscription to the first subscription. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus generally includes an interface configured to obtain at least one voice packet from an access point (AP), wherein the at least one voice packet is obtained during one or more service periods (SPs) of a target wake time (TWT) protocol, and a processing system configured to process the at least one voice packet obtained during the one or more SPs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect that a first subscription, of a plurality of subscriptions associated with the UE, is associated with an active service on a first cellular network. The UE may search, for a second subscription of the plurality of subscriptions, for radio access technologies (RATs) and frequency bands that are compatible with a dual active mode of the UE. In some aspects, the UE may detect that the active service on the first cellular network has ended. Accordingly, the UE may search, for the second subscription, for RATs and frequency bands that are compatible with the dual active mode of the UE and for RATs and frequency bands that are incompatible with the dual active mode, before expiry of a timer associated with a power saving state. Numerous other aspects are described.

Abstract: Methods and devices are disclosed for improving audio quality in a multi-subscription wireless communication device having a first subscription associated with a first radio frequency (RF) resource, and a second subscription associated with a second RF resource. The wireless communication device may detect an active voice call on a modem stack associated with the first subscription, detect an active voice call on a modem stack associated with the second subscription, determine whether audio data processing for the active voice calls will conflict in time based on a first packet exchange timeline and a second packet exchange timeline, and misalign the audio data processing for the active voice call on the modem stack associated with the second subscription in response to determining that audio data processing for the active voice calls will conflict in time.
