Abstract: One or multiple bit restricted access window (RAW) end point determination within for single user, multiple user, multiple access, and/or MIMO wireless communications. A RAW is defined in which only devices of the particular class (e.g., low power class, Z class, smart meter station (SMSTA) class, etc.) are allowed access to the communication medium. Indication of the end of such a RAW may be included within one or more bits set within a signal field (SIG) field of a framer packet generated by a given device within the system and transmitted to one or more other devices. After completion of the RAW, other respective devices of at least one other type of class may be provided access to the communication medium. The manner of access to the communication media outside of the RAW may be varied (e.g., scheduled, based on carrier sense multiple access/collision avoidance (CSMA/CA), etc.).

Abstract: Management frame map directed operational parameters within multiple user, multiple access, and/or MIMO wireless communications. A management frame map may be generated within and transmitted from a first wireless communication device to a group of other wireless communication devices. Thereafter, certain subsequently transmitted packets may be analyzed and processed by the receiving wireless communication devices based on that earlier received management frame map. One or more operational parameters are determined for a subsequently transmitted packet based on the previously received management frame map. The operational parameters govern the manner in which at least a portion of the subsequently transmitted packet is processed.

Abstract: Acknowledgment and/or receiver recovery mechanisms for scheduled responses within multiple user, multiple access, and/or MIMO wireless communications. Explicit scheduling information is provided from a first wireless communication device (e.g., an access point (AP), a transmitting wireless communication device) to a number of other wireless communication devices (e.g., wireless stations (STAs), receiving wireless communication devices) directing those other wireless communication devices a manner by which responses (e.g., acknowledgments (ACKs), block acknowledgments (BACKs), training feedback frames, etc.) are to be provided to the first wireless communication device there from. Such direction may include the order, timing, cluster assignment, etc. by which each respective wireless communication device is to provide its respective response to the first wireless communication device. In the event of the first wireless communication device failing to receive at least one response from at least one of the other wireless communication devices, various communication medium recovery mechanisms may be performed.

Abstract: A wireless communication device (alternatively, device) includes a processing circuitry configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications. A device generates and transmits a request to send (RTS) to group (RTG) frame to other devices. In response to the RTG frame, the device receives clear to send (CTS)(s) from one or more of the other devices and generates and transmits an orthogonal frequency division multiple access (OFDMA) data frame to those one or more of the other devices based thereon. The RTG frame can include different RTSs transmitted via different channels, sub-channels, sub-carriers, etc. to the different other devices.

Abstract: A relay wireless communication device is discovered using probe request. A source device that intends to transmit one or more frames to a destination device transmits the probe request to request a probe response from one or more potential relay devices. A relay device transmits a probe response to the source device when the relay device may operate to forward the one or more frames from the source device to the destination device. The relay device employs one or more considerations to determine its eligibility to serve as relay for the source and destination devices. The source device selects one of the potential relay devices based on their provided probe responses. The source device may select an optimal relay device based upon two or more received probe responses.

Abstract: Differential feedback within multiple user, multiple access, and/or MIMO wireless communications. After full feedback signal(s) have been received by a communication device (e.g., one that is to be performing beamforming for use in subsequent signal transmission), differential feedback signal(s) are received. Those differential feedback signal(s) are employed to update the full feedback signal(s) thereby generating updated/modified full feedback signals. Over time, such updated/modified full feedback signals may subsequently be further updated based upon later received inferential feedback signal(s). Such differential feedback signaling takes advantage of time and/or frequency correlation in a communication channel to provide for reduced feedback overhead by feeding back a difference or delta (Δ) relative to a previous value. For example, instead of providing full feedback signals in each respective/successive communication, feedback overhead is reduced by providing a difference or delta (Δ).

Abstract: Multi-user null data packet (MU-NDP) sounding within multiple user, multiple access, and/or MIMO wireless communications. Within communication systems including multiple wireless communication devices (e.g., one or more APs, STAs, etc.), channel sounding of the selected communication links between the various wireless communication devices is performed. A MU-NDP announcement frame is transmitted to and received by various wireless communication devices indicating which of those wireless communication devices (e.g., one, some, or all) are being sounded. Then, respective NDP sounding frames are transmitted via the communication links corresponding to those wireless communication devices (e.g., one, some, or all) are being sounded, and sounding feedback signals are subsequently sent back to the original transmitting wireless communication device. In some instances, after transmission of the MU-NDP announcement frame, a clear to send (CTS) is sent from at least one of the wireless communication devices thereby precipitating the transmission of the NDP sounding frames.

Abstract: Aspects of a method and system for medium access control (MAC) layer specialization for voice and multimedia data streams are presented. Aspects of the method include determining a number of attempts for transmitting one or more medium access control (MAC) frames. Aspects of the system may include a processor that enables determination of a number of attempts for transmitting one or more MAC frames. A maximum number for such attempts may be determined based on one or more priority levels associated with different portions of multimedia information being communicated via a wireless medium and contained within the one or more MAC frames.

Abstract: Session recovery after network coordinator or AP restart for single user, multiple user, multiple access, and/or MIMO wireless communications. Restart or reset of a network coordinator (e.g., an access point (AP) or other network coordinator type device) may occur for various reasons (e.g., a power cycle or power failure, inadequate failover protection, scheduled or planned power outages such as for including network maintenance, software upgrades, etc.). Upon determination of network coordinator restarted or reset, a singular bit within a communication from the network coordinator indicates synchronization or not of the its timing synchronization function (TSF) (e.g., with other devices in the communication system, such as wireless stations (STAs), smart meter stations (SMSTAs), etc.). A given device (e.g., STA, SMSTA, etc.) can provide its current TSF to the network coordinator so that it can resynchronize, re-establish its scheduled for wake times of those devices (e.g., target wake times (TWTs)), etc.
