    Abstract: Logic of an access point may transmit a null data packet for beamforming training and transmit a beamforming report poll to the first station on a user list before receiving a transmission from the first station on the user list. Logic may wait for a timeout period to determine whether the first station on the user list will respond to the null data packet prior to transmitting the beamforming report poll. Logic may receive from the first station an indication that the first station is a slow beamforming report responder. Logic may reorder the user list to position a fast beamforming responder as the first station. And logic of the station may determine that the station is unable to complete and transmit the report so the logic may wait to transmit the beamforming report in response to a subsequent beamforming report poll frame.

    Abstract: Examples are disclosed for techniques for allowing a wireless device to wake up a low power device while remaining compatible with other devices and wireless protocols. A first station determines that a low power device needs to wake up all or a portion of its circuitry in order to send and/or receive data from the first station. The first station sends a legacy preamble according to a standard wireless communication method such as according to IEEE 802.11 or Bluetooth addressed to the low power device. Legacy stations will recognize that a device is accessing the medium and will abstain from transmitting data during the transaction(s) between the first station and the low power device. The first station then sends a wake up payload according to a low power wireless communication method such as ASK or FSK to the low power device. The low power device recognizes the wake up payload and wakes up its main radio such as an IEEE 802.11 or Bluetooth radio. The first station sends and/or receives data to/from the low power device according to the standard wireless communication method. If there is no more data to send or receive, low power device powers down at least its main radio.

    Abstract: When a wireless communications device intends to communicate with another device over a wide channel consisting of multiple narrow channels, but detects interference on one or more of those narrow channels, it may restrict subsequent communications with that other device to those narrow channels that don't suffer from the interference. In one embodiment the device may simply refuse to monitor the interfering channel(s) for signals for a particular period of time. In another embodiment the device may use a CTS to signal the other device not to use the interfering narrow channel(s). That may result in using a wide channel with a reduced bandwidth for communications.

    Abstract: Logic for communications with an efficient acknowledgement (ACK) procedure for fragmented frames. Logic may determine an acknowledgement protocol to handle more fragments of a frame than the maximum that can be included in a bitmap of an NDP (null data packet) block acknowledgement (BlockACK). Logic may determine fragment indices to associate with an implicit ACK policy. Logic may read the Fragment Number field value in the Sequence Control field of a data frame to determine the fragment index. Logic may transmit an NDP BlockACK frame for every X fragments with fragment indices greater than X−1 so that L NDP BlockACK frames can acknowledge N fragmented frames. Logic may determine a bit number in a bitmap associated with a fragment index.

    Abstract translation: 用于与分段帧的有效确认(ACK)过程通信的逻辑。 逻辑可以确定处理帧的更多片段的确认协议,而不是可以包括在NDP(空数据分组)块确认(BlockACK)的位图中的最大值。 逻辑可以确定与隐式ACK策略关联的片段索引。 逻辑可以读取数据帧的序列控制字段中的片段编号字段值,以确定片段索引。 逻辑可以为片段索引大于X-1的每个X片段发送NDP BlockACK帧,以便L NDP BlockACK帧可以确认N个分片帧。 逻辑可以确定与片段索引相关联的位图中的位数。
