Abstract: Methods and device for user terminal based fast handoff are provided. User terminal builds a neighbor group list in which possible neighbor access points (APs) are divided into one or more groups. When a handoff needs to be prepared, the user terminal performs intermittently multiple pre-break probing subphases according to the neighbor group list while not breaking connection with a current serving AP. In each PBP subphase, signal qualities of neighbor APs in one group are probed in a manner of active probing. The user terminal selectively performs handoff according to the probed signal qualities of the neighbor APs. The user terminal may build the neighbor group list based on information of neighbor APs derived through overlapped channel scanning or information of neighbor APs received from the serving AP. The neighbor APs belonging to the same group work on the same channel and in each PBP subphase, a group of neighbor APs may be probed by using unicast probe request.

Abstract: Input streams for acoustic echo cancellation are associated with timestamps using reference times from a common clock. A render delay occurs between when an inbound signal is written to a buffer and when it is retrieved for rendering. A capture delay occurs between when a capture signal is written to a buffer and when it is retrieved for transmission. Both the render delay and the capture delay are variable and independent of one another. A render timestamp applies the render delay as an offset to a reference time at which the inbound signal is written to the buffer for rendering. A capture timestamp applies the capture delay as an offset to a reference time at which when the capture signal is retrieved for transmission. Applying the delay times as offsets to the reference times from the common clock facilitates synchronizing the streams for echo cancellation.
