Abstract:
Techniques for setting up a packet-switched video telephony (PSVT) call are described. A mobile originated (MO) device may transmit an invitation for the PSVT call to a mobile terminated (MT) device. The invitation may initiate a process to reserve and identify video and audio resources to establish the PSVT call. The MO device may determine whether the video resources are available. If the video resources are not available but audio resources are available, the MO device may instead establish the PSVT call with only an audio stream call between the MO device and the MT device. If audio resources become available ahead of video resources, the PSVT call may be established with an audio stream first and a video stream is automatically added to the call when video resources are reserved later, or the PSVT call is downgraded to a VoIP call if the video resources cannot be reserved.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, during an active call on a first radio access technology (RAT), a signal strength associated with the first RAT is within a particular range above a handover threshold. The UE may determine, based at least in part on a signal strength of a second RAT, that the active call would be moved from the second RAT to a third RAT after a handover from the first RAT to the second RAT, and, may trigger mobility from the second RAT to the third RAT based at least in part on the determination that the signal strength associated with the first RAT is within the particular range and the determination that the active call would be moved from the second RAT to the third RAT. Numerous other aspects are provided.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify an indication of an occurrence of a handover. The UE may adjust a delay used by a buffer based at least in part on the indication of the occurrence of the handover. The UE may process one or more packets of the buffer based at least in part on the adjustment of the delay used by the buffer. Numerous other aspects are described.
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:
Various embodiments include methods performed by a processor of a computing device for managing Radio Access Technology (RAT) capability during a Wireless Local Area Network (WLAN)-only mode. Various embodiments may include determining whether the computing device is in a WLAN-only mode, and removing circuit-switched RATs from the RAT capability of the computing device in response to determining that the computing device is in the WLAN-only mode. This determination may be made during system bootup of the computing device, upon detecting the change in the WLAN settings and/or based on a notification message from a multimedia subsystem indicating that the computing device is in the WLAN-only mode. Some embodiments may further include transmitting a service request with only packet-switched (PS) RATs included in a RAT priority list to a Non-Access Stratum (NAS) layer of the computing device, in which the PS RATs include Long Term Evolution (LTE) and New Radio (NR).
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may set a target delay value for a dejitter buffer of the UE based at least in part on jitter delays of silence descriptor (SID) packets that are received by the UE. The UE may receive, after the SID packets, media packets into the dejitter buffer. The UE may release the media packets from the dejitter buffer based at least in part on the target delay value. Numerous other aspects are described.
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.
Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first communication connection associated with a first subscription or associated with a first network slice, wherein the first communication connection is a default connection for the UE for data traffic. The UE may establish a second communication connection associated with a second subscription or associated with a second network slice. The UE may receive, from a device via a wireless local area network provided by the UE or via a wired connection, a data traffic packet associated with one or more parameters. The UE may route the data traffic packet to the second communication connection based at least in part on the one or more parameters. The UE may transmit the data traffic packet using the second communication connection. Numerous other aspects are described.
Abstract:
Various embodiments include methods and user equipment (UE) for mobile-terminated call handling when a latency-sensitive service (LSS) is active on the UE. Embodiments may include determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation and determining whether a latency-prone service command is received that includes service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS. In response to determining that a latency-prone service command is received the MT call invitation may be rejected, but in response to determining that a latency-prone service command is not received, MT call alerting may be allowed.
