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: 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 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: 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 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.

Abstract: A user equipment (UE) expedites cell reselection by reselecting a neighbor cell prior to call setup. In one instance, the UE measures a signal quality of a serving cell and a signal quality of the neighbor cell. The UE starts a reselection timer for reselecting the neighbor cell based on the measured signal quality of the serving cell and the measured signal quality of the neighbor cell. The UE reselects the neighbor cell prior to a scheduled expiration of the reselection timer.

Abstract: A user equipment (UE) expedites cell reselection. In one instance, the UE starts a reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.
