摘要： A wireless access device transmits encoded media streams to at least first and second clients over a shared wireless channel. First and second transmission windows are established in a transmission frame interval for transmission of media packets to the first and second clients, respectively. An unused portion of one of the transmission windows is identified using, for example, transmission status information (from the wireless access device) associated with the media packets. The unused portion of the transmission window is adaptively reallocated for use in transmission of media packets associated with the other transmission window. In one mode of operation, the reallocation process may trigger a reversal in the order of the first and second transmission windows in subsequent transmission frame intervals.

摘要： Polling using B-ACK for occasional back-channel traffic in VoWIFI applications. Within wireless communication systems having a relatively asymmetric channel (e.g., relative more downstream traffic than upstream), certain upstream communications (e.g., acknowledgments (ACKs) and/or block acknowledgments (B-ACKs)) include indication therein (e.g., piggybacked therein) that a given downstream located communication device desires/needs to make upstream communication. In some instances, specificity is also provided therein to indicate the type of information to be transmitted upstream. Such a communication protocol mitigates (or eliminates) contention between upstream and downstream traffic in an environment with significantly more downstream traffic (e.g., such as ongoing downstream traffic that may include streaming video). A coordinating device (e.g., access point (AP)) may employ such upstream provided indicia to coordinate upstream and downstream communications within the wireless communication system in a non-contentious manner that does not deleteriously affect ongoing downstream traffic.
