Abstract: Methods, systems, and devices for wireless communications are disclosed by the present application. A request to establish a call using a first connection may be received, the first connection using a first radio access technology to communicate with a radio access network. During execution of a procedure to establish the call, a command to handover communications from the first connection to a second connection that uses a second radio access technology to communicate with the radio access network may be received. The second connection may be established in response to the command, and a message indicating that the request to establish the call was successfully received may be transmitted over the second connection. Also, a message indicating that an alert of the call is being issued may be transmitted over the second connection.

Abstract: Embodiments include systems and methods for wireless device signaling a network regarding customized ringing signal (CRS) capability and use of such information by the network. Various embodiments may receiving from the network an INVITE message notifying the wireless device of an incoming call, determining whether the INVITE message indicates that the network provides CRS service if the wireless device supports a CRS function, and including an indication in a response to the INVITE that the wireless device supports the CRS function in response to determining that the INVITE message includes an alert information header field indicating that the network provides CRS service. Various embodiments include a network computing device receiving such information and performing negotiations for CRS service with the wireless device only if the wireless device indicates CRS functional capability.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station associated with a first radio access technology (RAT), a neighbor cell list including entries for at least a first set of neighbor cells and a second set of neighbor cells, the first set of neighbor cells and the second set of neighbor cells associated with a second RAT. The UE may determine that the first set of neighbor cells is associated with a first network operator and that the second set of neighbor cells is associated with a second network operator. The UE may measure at least one neighbor cell of the neighbor cell list based at least in part on prioritization of the first set of neighbor cells relative to the second set of neighbor cells. Numerous other aspects are described.

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 receive, via a first connection of a dual connectivity mode, a first packet having a first sequence number. The UE may receive, via a second connection of the dual connectivity mode, a second packet having a second sequence number. The UE may determine, based at least in part on the first sequence number and the second sequence number, that the first packet is received out of order. The UE may maintain a packet order for reception of subsequent packets via the first connection or the second connection. The UE may drop the first packet based at least in part on the determination that the first packet is received out of order. Numerous other aspects are provided.
