    Abstract: A wireless communication device (alternatively, device, WDEV, etc.) includes a 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 generates and transmits a first signal that includes a field that specifies an acceptable interference level (AIL) for concurrent communication for use by a first other WDEV to determine whether a transmission from the first other WDEV to a second other WDEV acceptably or unacceptably interferes with another transmission from the WDEV. Concurrent communication (e.g., from the WDEV to a third other WDEV, and from the first other WDEV to the second other WDEV) may be made when the AIL compares favorably with the AIL.

    Abstract: A wireless communication device (WDEV) receives, detects, snoops, etc. (generally, “receives”) signals that are transmitted between two other WDEVs and extracts information therefrom to determine the location of the WDEV. These signals can include fine timing measurement (FTM) and/or timestamps related information as part of a frame exchange procedure between those two other WDEVs. A new protocol specifies when such an FTM and/or timestamps frame exchange procedure is performed between the two other WDEVs, and the WDEV intelligently detects/receives such signals at such specified times. When the WDEV operates in a reduced power or sleep state, the WDEV awakens from the reduced power or sleep state at the appropriate times to detect FTM and/or timestamps related information of such a frame exchange procedure. The WDEV then can process such FTM and/or timestamps related information for use in determining the location of the WDEV relative to the two other WDEVs.

    Abstract: A signaling protocol allows for speed frame exchange between different wireless communication devices within single user, multiple user, multiple access, and/or MIMO wireless communication system. A listening wireless communication device analyzes state of speed frame indicator bits within frames transmitted from a first other wireless communication device to determine the entire radio frame exchanges between that first other wireless communication device and a second other wireless communication device. The second other wireless communication device may be a hidden node relative to the listening wireless communication device such that all or less than all transmissions from the hidden node are received by the listening device. The listening wireless communication device determines the status of the communication medium (e.g., the air in the context of a wireless communication system), so that it can transmit successfully without interfering with any ongoing communications between the first and second other wireless communication devices.

    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 (e.g., generally, a device) includes a communication interface and a processor configured to support communications with one or more other devices. In an example of operation, the device supports first communications based on a first communication protocol with a first network coordinator device and identifies a second network coordinator device that operates based on a second communication protocol when supporting those first communications. The device also determines one or more operational parameters associated with the second network coordinator device. When one or more conditions is/are appropriate, the device interworks the first communications and second communications based on the second communication protocol with the second network coordinator device. The degree of interworking is based on one or more considerations associated with one or more of the first and second communication protocols, the first and second network coordinator devices, local and/or remote operating conditions, etc.

    Abstract: A transceiver of an apparatus supports communication with at least one additional apparatus. A processing module processes at least a portion of media access control (MAC) header content of a MAC frame within a signal received via the at least one transceiver or generated internally. In particular, the MAC header content, and optionally the MAC payload content, is processed based on a filter and classification agreement between the apparatus and the at least one additional apparatus to classify the MAC frame.
