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 enhanced beamforming procedure to achieve spatial reuse and thereby improving cell edge performance and area throughput is proposed. The enhanced beamforming method increases the likelihood of channel access under dense deployment condition, reduces interference to OBSS, reduces collision during reception, and increases the likelihood of spatial reuse in dense deployment scenario thus leading to higher network throughput.

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.

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 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.
