摘要： A data unit (e.g., a physical layer convergence procedure (PLCP) protocol data unit (PPDU)) is detected at a first wireless device of a basic service set (BSS). The data unit was sent on a channel from a second wireless device of an overlapping basic service set (OBSS). The data unit is wide-bandwidth, occupying both a primary channel and a secondary channel of the wireless network. The first and second wireless devices are within a same spatial reuse group (SRG). The first wireless device stores the channel bandwidth of the data unit and a receive duration time of the data unit. During the receive duration time of the data unit, a SRG OBSS power density threshold is applied on the secondary channels that are within the channel bandwidth of the data unit, instead of applying a non-SRG OBSS power density threshold on those secondary channels.

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 data unit (e.g., a physical layer convergence procedure, PLCP, protocol data unit, PPDU) is detected at a first wireless device that is a member of a basic service set, BSS (802). The data unit was sent on a channel from a second wireless device that is a member of an overlapping basic service set, OBSS. When the first wireless device ignores the data unit (806) and obtains a transmit opportunity (808) for the channel according to a spatial reuse procedure, then the first wireless device is prohibited from transmitting a frame to a device that is a member of the OBSS during the time interval associated with the transmit opportunity (810).

摘要： A method of indoor positioning using Fine Timing Measurement (FTM) avoiding co-located access point (AP) is proposed. In a wireless local area network, an AP obtains neighboring AP location information and determines a list of co-located BSSIDs. In a first option, an STA first selects an AP and query for AP location and co-located BSSID information using ANQP (Access Network Query Protocol). In a second option, the STA first selects an AP and initiates FTM protocol with the selected AP and thereby obtaining AP location and co-located BSSID information. Upon obtaining the AP location and the co-located BSSID list, the STA can initiates FTM protocol with additional non-co-located BSSs for determining an accurate STA location.

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 determining a distance between mobile wireless devices can include determining a format and bandwidth supported by an initiating Station (STA) and a responding Station (STA) and exchanging one or more sets of Null Data Packet (NDP) frames between the initiating Station (STA) and the responding Station (STA) using the determined format and bandwidth. The distance between the initiating Station (STA) and the responding Station (STA) can then be determined based on timing measurements of the one or more sets of Null Data Packet (NDP) frames exchanged between the initiating Station (STA) and the responding Station (STA).

摘要： A method and apparatus for supporting A-MSDU data transfer in an A-MPDU includes sending capability information from a first network device, receiving onto the first network device an A-MPDU frame that includes A-MSDU data, and sending an acknowledgment from the first network device. A bit field in the capability information indicates if inclusion of A-MSDU data in an A-MPDU is supported. The first network device is a wireless station (STA). The first network device is part of a peer-to-peer network. The A-MSDU is in a data enabled immediate response context. A bit field in the capability information indicates if receiving an A-MPDU frame including A-MSDU data carried in a QoS Data frame without a block acknowledgment agreement is supported.

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.
