摘要： The invention provides devices, systems, methods and software for allowing interoperability between legacy stations and extended-range stations in a wireless network By way of example, an access point is configured to transmit communications in a first mode and/or a second mode The first mode might not employ extended-range technology, such that communications transmitted in the first mode can be received and/or interpreted by legacy stations, while the second mode might employ extended-range technology, such that communications transmitted in the second mode can be received by extended-range stations outside the range of basic-range communications As another example, the access point is configured to establish transmission Vflndows,' such that legacy stations are free to transmit duπng a first time peπod, in which extended-range stations are prohibited from transmission, followed by a second time peπod, in which extended-range stations are free to transmit, while transmission from legacy stations is prohibited.

摘要： Circuits, methods, and apparatus that provide high-throughput control fields that, among other functions, provide efficient TXOP handoffs in wireless networks. A handoff may be made by setting one or more bits in a field in a QoS frame, such as the HT control or other appropriate field.. Various conditions may be placed on a handoff by a granting station. For example, conditions specifying where a station receiving a TXOP handoff may send data, what the receiving station may do with any remaining TXOP, or what types of data may be transmitted by the receiving station may be imposed. These various conditions may be combined or omitted in any logic combination.

摘要： This disclosure provides methods, devices and systems for radio frequency (RF) sensing in wireless communication systems. In some implementations, a transmitter device transmits sounding sequences configured for channel estimation over a wireless channel to a receiver device. The transmitter device also transmits or receives non-sounding frames associated with a channel report of the receiver device. The transmitter device transmits a frame soliciting the channel report from the receiver device. The transmitter device receives the channel report, which may include channel state information (CSI) of the wireless channel responsive to at least the sounding sequences. Some types of channel reports may take longer to generate than other types of channel reports. Transmitting or receiving the non-sounding frames during the time period may prevent other devices from accessing the wireless channel when the receiver device needs additional time to generate a certain type of channel report.

摘要： Generally, the described techniques provide for protection mechanisms for sounding training signals transmitted between wireless devices when performing ranging sounding estimation. For example, sounding training signals may be encoded to include a sequence of phase rotations or cyclic shifts to protect the sounding training signal from peer devices. In some cases, encoding information associated with a long training field (LTF) may be transmitted either before or after the LTF is transmitted. Additionally or alternatively, a time delay may be introduced to the sounding training signal, where timing information may be removed from one or more fields of the sounding training signal and the time delay may be appended to an interframe spacing. Alternatively, a frame may be split into multiple frames with the sounding training signal in a first frame, and timing information in a second frame that is offset in time from the first frame.

摘要： This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for enhanced channel selection in a network having multiple access points (APs). The enhanced channel selection may optimize the overall performance of the network by incorporating considerations about the impact on other APs in a big-picture view of the network. In one aspect, enhanced channel selection may combine a first channel selection process at a first AP (based on first channel selection by the first AP) with a second channel selection at a Multi-AP Controller. Coordination between the first AP and the Multi-AP Controller may improve a channel selection technique to optimize channel selection based on considerations of the overall network.

摘要： This disclosure provides systems, methods and apparatus, including computer programs encoded on computer-readable media, for steering an association of a device in a network having multiple access points (APs). In one aspect, a first AP can obtain per-AP metric information regarding a plurality of other APs in the network. The per-AP metric information may include backhaul performance information regarding at least one wireless backhaul channel in the network. The per-AP metric information may include an estimated air time fraction value reported by the other APs. A selection to steer the device from the first AP to a second AP can be based, at least in part, on the per-AP metric information. In some implementations, a Multi-AP Controller can redistribute per-AP metric information collected from multiple APs in the network. In some implementations, a topology of the network may be optimized by steering a child AP to another wireless backhaul link.

摘要： This disclosure provides systems, methods, and apparatuses for implementing changes to Basic Service Set (BSS) parameters of an access point (AP) in a synchronized manner across multiple physical layer (PHY) formats. In some implementations, an AP may enable STAs that use different PHY formats to implement the changes at substantially the same time. For example, the change in BSS may be aligned with a target beacon transmission time (TBTT) of a first PHY format, and the AP may broadcast information, in a second PHY format, pointing to the TBTT of the first PHY format. In some other implementations, the AP may enable the STAs to implement the changes at different times. For example, STAs using a first PHY format may implement the change at a TBTT of the first PHY format, whereas STAs using a second PHY format may implement the change at a TBTT of the second PHY format.

摘要： Adaptive threshold selection in overlapping basic service set (OBSS) packet power save (PPS) is discussed in which a mobile device may monitor transmissions from at least one OBSS access point and activate a dynamic OBSS PPS with an initial nap threshold in response to the transmissions from the at least one OBSS access point exceeding a predefined threshold. The mobile device may calibrate the initial nap threshold. Such calibration may include monitoring a set of throughput parameters associated with throughput of a basic service set (BSS) access point in response to the activating and adjusting the initial nap threshold in response to changes in one or more throughput parameters of the set of throughput parameters.

摘要： Methods, systems, and devices for wireless communication are described. An access point (AP) may win access to an unlicensed frequency channel for a transmission opportunity. For the transmission opportunity, the AP may dynamically schedule a duration of time to be used for uplink transmissions and a duration of time to be used for downlink transmissions. The schedule may be based on a comparison of values for a parameter monitored by the AP. The parameter may be monitored for uplink traffic and for downlink traffic. The parameter may indicate the latency experienced by each direction of traffic, or an intolerance of each direction of traffic to delay. The AP may schedule the uplink and downlink durations to compensate for the discrepancy in latency between the two directions of traffic.

摘要： Methods, systems, and apparatuses are described for adaptive dwell time for scan procedures. A wireless station (STA) may identify a scan period during which a passive scan procedure is performed on a first channel. The STA may analyze a channel congestion metric during at least a portion of the scan period. The STA may transition from the passive scan procedure to an active scan procedure on the first channel during the scan period based at least in part on the analyzed channel congestion metric.
