    Abstract: A multi-user super-frame (MU-SF), as controlled by a MU-SF owner, is used to govern the manner by which various wireless communication devices have access to the communication medium. When various wireless communication devices operate within a wireless communication system, communication medium access can be handled differently for wireless communication devices having different capabilities. Per the MU-SF, those having a first capability may get medium access in accordance with a first operational mode (e.g., carrier sense multiple access/collision avoidance (CSMA/CA)), while those having a second capability may get medium access in accordance with a second operational mode (e.g., scheduled access). The respective durations for each of the first operational mode and the second operational mode within various MU-SFs need not be the same; the respective durations thereof may be adaptively modified based on any number considerations.

    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).

    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: Time division multiple access (TDMA) media access control (MAC) adapted for single user, multiple user, multiple access, and/or MIMO wireless communications. Various com systems may include smart meter stations (SMSTAs) and/or wireless stations (STAs). Appropriate coordination is made with respect to such communication devices to ensure appropriate uplink (and/or downlink) communications between a network manager or coordinator (e.g., an access point (AP)) and the SMSTAs and/or STAs. With respect to SMSTAs, the relative duration of time that such communication devices are awake and operative versus asleep (or in a reduced power and/or functionality state) can be significant. Certain implementations may include a relatively large number of such communication devices (e.g., 10s, 100s, 1000s, or more), and appropriate coordination and scheduling of such communications to/from them is made using one or more variations of TDMA signaling (e.g., including different respective service periods (SPs), communication medium access operational modes, adaptation thereof, etc.).

    Abstract: Response frame modulation coding set (MCS) selection within single user, multiple user, multiple access, and/or MIMO wireless communications. With respect to any exchange between communication devices in which there is a response frame, a first frame (e.g., an eliciting frame) is a first transmitted from the eliciting communication device to the responding communication device, and a second frame (e.g., a response frame) is transmitted from the responding communication device to the eliciting communities device. Appropriate selection of MCS to be used within the response frame may be determined explicitly or implicitly. One or more parameters (e.g., a limit parameter, a reduction parameter, etc.) may be used to determine the MCS of the response frame. The MCS employed for a response frame may be selected from a basic MCS set that ensures all response frames from any responding communication device may be properly received by the eliciting communication device.
