  • Patent number: 9635647
    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.

  • Patent number: 9622247
    Abstract: Preamble and header bit allocation for power savings within multiple user, multiple access, and/or MIMO wireless communications. Within a multi-user packet, information (e.g., partial address information) related to a recipient group of wireless communication devices (e.g., as few as one wireless communication device or any subset of a number of wireless communication devices, sometimes including all of the wireless communication devices) is emplaced within a PHY (e.g., physical layer) header of such a multi-user packet to be communicated within a multi-user (MU) environment. Such recipient indicating information can be encoded with relatively higher robustness (e.g., lower coding rates, lower ordered modulation, cyclic redundancy check (CRC), etc.) that remaining portions of the multi-user packet. Various portions of the remainder of the multi-user packet may respectively correspond to different wireless communication devices (e.g.

  • Patent number: 9621474
    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).

    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.

  • Patent number: 9456306
    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.

  • Patent number: 9439219
    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.
