摘要： Methods and apparatus are provided for a many to one communication protocol. In one novel aspect, a modified CTS is sent by a receiving wireless communications station in response to a regular RTS. The modified CTS includes an indication for an uplink MU operation. In one embodiment, a modified CTS indicates a restricted access window (RAW) followed by RAW parameter set (RPS). In one embodiment, a subset of wireless communications devices associated with the receiving wireless communications station sends modified PS-poll with uplink data indication. Such PS-poll traffic is protected from passerby wireless communications devices from an OBSS. The receiving wireless communications station sends a modified resource-allocation map frame followed by a regular CTS frame. The subsets of wireless communications devices send their uplink data based on the received resource allocation map. The RTS-originating wireless station either sends its data frame earlier or concurrently with other wireless communications devices.

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： Embodiments of the present invention are drawn to systems, apparatus and methods that provide TSF information for a non-primary link to a non-AP STA operating on a primary link to avoid IDC interference and improve wireless throughput and efficiency. The TSF information includes a TSF offset value used to determining the timing of subsequent transmissions over different wireless links. The TSF offset value can be carried in a beacon frame, probe response frame, association frame, through a Reduced Neighbor Report element or a multi-link element, for example. Beacon frames can include timestamp and TSF offset information transmitted periodically. Some wireless links may share a TSF clock or have fixed TSF offsets.

摘要： A method of sounding and feedback with channel quality information and reduced overhead is provided. A receiving station receives a sounding signal transmitted from an access point over multiple sub-channels of a wide channel in a wireless network. The receiving station detects channel quality based on the received sounding signal for each sub-channel. The receiving station then performs channel estimation based on the received sounding signal and thereby determining feedback information. Finally, the receiving station transmits a feedback message to the access point, the feedback message contains NULL feedback information, reduced feedback information, or channel integrity/quality indicators based on the channel quality information for each sub-channel. Based on the feedback message, the access point may repeat the sounding process, narrow the transmission bandwidth, or select only stations who have indicated uncorrupted channel sounding for MU-MMO transmission.

摘要： System and method of using an AP to individually controlling RTS/CTS duration thresholds for multiple STAs in a WLAN. In response to a STA's association request, the AP determines a duration threshold specific to the STA and encloses this information in an association request response for transmission to the STA. By using a broadcast frame, the AP may instruct multiple STAs to uniformly update their stored duration thresholds. For example, if the duration threshold field in the beacon frame is set to 0, the multiple STAs preserve their current duration thresholds; if the field is set to a non-zero value less than 1023, the multiple STAs all update their duration thresholds to the non-zero value; if this field is set to 1023, the multiple STAs disable the RTS/CTS transmissions. Based on a current threshold and pertinent policies, an STA can decide whether to initiate an RTS/CTS transmission sequence.

摘要： An apparatus capable of multi-link operations with respect to a first link and a second link obtains a second transmission opportunity (TXOP) on the second link after one other apparatus has started a first TXOP on the first link. The apparatus performs one or more transmissions during the second TXOP on the second link such that the second TXOP is at least partially synchronized with the first TXOP on the first link.

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). 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 and obtains a transmit opportunity 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.
