    摘要： The deferral mechanism described herein may improve medium reuse in a wireless network with transmit power imbalances. For example, in one embodiment, an apparatus employing the deferral mechanism described herein may comprise a receiver to sense a data unit transmitted on a medium associated with the wireless network, wherein the data unit may comprise information indicating a transmit power associated therewith. Furthermore, the apparatus may comprise one or more processors to initiate a transmission on the medium associated with the wireless network if the apparatus is not an intended receiver of the sensed data unit, the transmit power associated with the data unit exceeds a transmit power associated with the apparatus, and a received power associated with the data unit does not equal or exceed a clear channel assessment threshold plus a difference between the transmit power associated with the data unit and the transmit power associated with the apparatus.

    摘要： A method includes creating a plurality of data fragments from a single data unit. The method also includes transmitting the plurality of data fragments to a receiver and receiving an acknowledgement from the receiver after transmitting a last data fragment of the plurality of data fragments. The method further includes selectively interpreting the acknowledgement as a multi-fragment acknowledgement (MFA) in response to a value of a fragment sequence number (FGSN) of the last data fragment. The MFA indicates receipt or non-receipt by the receiver of each of the plurality of data fragments of the single data unit.

    摘要： A method is provided for wirelessly transmitting from a transmitter to one or more receivers within a multi-user (MU) multiple-input and multiple-output (MIMO) communication system. A number of concurrent (spatial) streams are dynamically allocated in a MU-MIMO transmission to each of a plurality of served receivers to maximize total data transmitted on each transmission. Streams are allocated according to a corresponding transmission queue length for each receiver and the number of receive antennas used by each of the served receivers. A transmission timer is started upon sending the transmission. A random backoff counter is also started upon one of either: (a) expiration of the transmission timer or (b) receipt of data at a transmission queue. A new transmission is sent upon expiration of the random backoff counter if the transmission timer has expired. Otherwise, the random backoff counter is restarted one or more times until the transmission timer has expired.

    摘要： Systems, methods, and devices for acknowledging communications from a plurality of wireless devices in a wireless network are described herein. In some embodiments, an access point for the wireless network transmits a group acknowledgment (ACK) to indicate whether communications (packets) from the plurality of wireless devices have been received or correctly decoded within some time interval. Each wireless device may have a different time interval associated with it. For some embodiments, the time interval for a wireless device is relative to when a previous group ACK was sent. A group ACK may include a bitmap. In some embodiments, the bitmap indicating whether a communication has been received or correctly decoded may be transmitted as part of a beacon.
