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 embodiments include methods for determining when to resynchronize voice-over IP (VoIP) communications of the wireless device. Various embodiments may include storing one or more first call characteristics of the VoIP communications between the wireless device and a first base station, detecting whether the VoIP communications are transferred from the first base station to a second base station, analyzing one or more second call characteristics of the VoIP communications between the wireless device and the second base station, determining whether the one or more second call characteristics differ from the one or more first call characteristics, determining, within a total wait time, whether no active voice frames will be transmitted across an uplink, or no active voice frames will be provided to audio decoding, resynchronizing the VoIP communications in response to determining that the one or more second call characteristics differ from the one or more first call characteristics.

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value, to determine a receive time of a first audio packet of a talk spurt, to determine a target delay value associated with a de-jitter buffer based on the arrival delay value and the receive time of the first audio packet. The apparatus also includes a decoder timing control circuitry configured, in response to detecting the first audio being dequeued from the de-jitter buffer, to cause a decoder to start decoding of the first audio packet.

Abstract: Methods, systems, and devices for audio dejittering are described. The method may include determining a mean delay applied to packets in a packet voice communication system, calculating, from the mean delay, a standard deviation for at least a subset of packets in a talk spurt, determining a target delay for the talk spurt by applying a moving average to the standard deviation, and applying the target delay to a first packet from the talk spurt.

Abstract: A device includes a receiver configured to wirelessly receive packets associated with a packet-based communication. The device includes a high-speed motion detector configured to determine whether motion data corresponding to an end device of the packet-based communication indicates a high-speed condition of the end device. The device also includes a high-speed motion compensator configured to adjust a configuration setting associated with the packet-based communication in response to the motion data indicating the high-speed condition.

Abstract: An apparatus includes de-jitter buffer control circuitry configured to determine an arrival delay value based on previously received audio packets, to identify a receive time of a first audio packet of a talk spurt, to determine an offset value of the first audio packet based on the receive time and the arrival delay value, and to adjust a target delay value associated with a de-jitter buffer based on the offset value. The apparatus also includes a de-jitter buffer configured to buffer the first audio packet based on the adjusted target delay value.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify a cycle length associated with a discontinuous communication mode, determine a frame duration associated with the discontinuous communication mode, select a redundancy offset that is greater than or equal to the cycle length, and communicate with a second device in the discontinuous communication mode using the redundancy offset. The device may generate a first frame that includes a set of data and a second frame that includes at least a subset of the set of data and may transmit the first frame at a first time and the second frame at a second time that is separated from the first time at least by the redundancy offset. A device may receive a first frame at a first time and a second frame at a second time that is separated from the first time by the redundancy offset.
