Abstract: An apparatus and methods are provided for opportunistically conducting data communications on multiple wireless channels. In these methods, a device is engaged in data communications with a second device and receives a conflicting communication demand requiring action on one or more channels other than the data-communication channel (e.g., to conduct a channel scan, to issue or receive a beacon). The device arranges a schedule of channel switches to satisfy the communication demand and advises the second device of the schedule, and may explicitly invite the second device to implement the schedule. To the extent the second device does so, the data communications continue on the other channels. The devices may be participating in a synchronized peer-to-peer communication environment that requires their attendance on the data-communication channel and that is not associated with the other channels.

Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. In prior art designs, the instantaneous jitter is derived from a weighted history of the media stream, and consequently only packets that have already arrived are used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.
