摘要： A method of data acknowledgement includes: transmitting data from a wireless station, transmitting a Block Acknowledgement Request (BAR) from the wireless station, and receiving a Block Acknowledgement (BA) by the wireless station. In one example, the step of transmitting BAR by the wireless station requests an acknowledgment for transmitted data with an access category that has the same priority as the a primary access category. In another example, the step of transmitting BAR by the wireless station requests an acknowledgment for transmitted data with an access category that has the same or higher priority than a primary access category. A wireless device includes at least one transceiver to exchange data with another wireless device, at least one processor, and a memory storing instructions that, when executed by the one or more processors, cause the wireless device to: transmit data, transmit a Block Acknowledgement Request (BAR), and receive a Block Acknowledgement (BA).

摘要： A method of a ranging and positioning with sensor STA/neighbor AP is proposed. An initiating wireless device establishes an FTM procedure with a responding wireless device in an indoor wireless local area network. The initiating device exchanges FTM frames with the responding device and thereby receiving a first set of timestamps from the responding device. The initiating device receives a second set of timestamps associated with the exchanged FTM frames from one or more listening devices. Finally, the initiating device determines location information from the first and the second set of timestamps.

摘要： A method of indoor positioning using Fine Timing Measurement (FTM) protocol with multi-antenna access point (AP) is proposed. In a wireless local area network, an AP has multiple antennas that are strategically located in different physical locations. The AP is used to exchange FTM frames with a wireless station for timing measurement of the FTM frames via its multiple antennas independently. The timing measurement result (e.g., timestamps of transmitting and receiving FTM frames) is then used to determine an absolute location of the station. A simplified Indoor Location operation with simplified deployment is achieved.

摘要： A method of reducing the usable channel bandwidth and increasing the channel bandwidth at run time is provided. The method allows a receiving wireless communications device to inform its corresponding transmitting communications device to either increase, reduce, or maintain the number of usable narrow band channels for the succeeding frame exchange. In a wireless communications channel, channel reduction is accomplished by using a usable channel indicator in a response frame responding to the preceding receiving frame. The usable channel indicator is the means for the receiving communications device to inform the transmitting communications device the preferred narrow band channels that it deems having good channel characteristics.

摘要： A method of supporting incompatible channelization in a wireless communications system is provided. A coordinating device determines a first set of physical parameters of a first wireless channel. The first set of physical parameters includes a channel bandwidth, a central frequency, a transmit power limit, and a modulation and coding scheme. The coordinating device establishes communication with a first set of communications devices over the first wireless channel. The coordinating device then broadcasts a channel-adjustment message and determines a protection period. The channel-adjustment message comprises a set of instructions on how to adjust to a second set of physical parameters of a second wireless channel. A second set of communications devices adjust physical parameters based on the channel-adjustment message. Finally, the coordinating device communicates with the second set of communications devices over the second wireless channel during the protection period.
