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: 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 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.
