    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: A method for multiple input multiple output wireless communication begins by determining protocols of wireless communication devices within a proximal region. The method continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by determining the number of transmit antennas. The method continues, when the protocols of the wireless communication devices within the proximal region are of the like protocol, formatting a preamble of a frame of the wireless communication utilizing at least one of cyclic shifting of symbols, cyclic shifting of tones, sparse tone allocation, and sparse symbol allocation based on the number of transmit antennas.

    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: Communications are coordinated between different respective wireless communication device groups in a multiple delivery traffic indication map (DTIM) per device signaling scheme. Different respective wireless communication devices (e.g., wireless stations (STAs)) may communicate with a manager/coordinator wireless communication device (e.g., access point (AP)) at different times and for different reasons. The manager/coordinator wireless communication device generates and transmits beacons to the wireless communication devices specifying times during which communications may be supported with the manager/coordinator wireless communication device. A restricted access window (RAW) information element (IE) within a beacon includes at least one restricted access window (RAW) to specify a wireless communication device authorized to communicate with the manager/coordinator wireless communication device. Different wireless communication device groups may communicate with the manager/coordinator wireless communication device at different periodicities, and any one wireless communication device may be included in more than one wireless communication device group.

    Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(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 WDEV(s) and to generate and process signals for such communications. A WDEV determines capabilities of other WDEVs and generates a first orthogonal frequency division multiple access (OFDMA) frame that includes resource unit (RU) allocation specified for the other WDEVs and media access controller (MAC) padding (e.g., selected based on capability of at least one of the other WDEVs. The WDEV then transmits the first OFDMA frame to the other WDEVs to be processed by them and then receives a second OFDMA frame from the other WDEVs based on the RU allocation.

    Abstract: A relay wireless communication device is implemented to perform buffer management and coordination with a source wireless communication device. A relay wireless communication device (generally, a relay) informs a source wireless communication device (source) of the status of memory therein to store messages intended for a destination wireless communication device (destination). For example, the source transmits information to the relay, which buffers information before forwarding it on to the destination. This buffering may be a function of the source having additional information intended for the relay and/or destination. The relay performs appropriate signaling, such as suspend transmission requests and resume transmission requests, to inform other devices in the system of its memory storage status (e.g., such as when having an actual or anticipated overflow). In one implementation, a suspend transmission request may be implemented by setting a particular bit within a communication from the relay to the source.

    Abstract: Mixed mode operations within multiple user, multiple access, and/or MIMO wireless communications. Certain communication systems can include wireless communication devices of various capabilities therein (e.g., IEEE Task Group ac (TGac VHT), IEEE 802.11 amendment TGn, IEEE 802.11 amendment TGa, and/or other capabilities, etc.). In one manner of classification, wireless communication devices having legacy and newer/updated capabilities may inter-operate with one another, operate within a common region, and/or communicate via a common access point (AP). Coordination of such wireless communication devices (e.g., legacy and newer/updated) provides for their respective operation on a same set of clusters in accordance with various operational modes including: (1) time dividing medium access between the wireless communication devices of various capabilities, (2) assigning primary cluster(s) for a first capability set and assigning non-primary cluster(s) for a second capability set, etc., and/or (3) any combination of operational modes (1) and (2).
