Abstract: Measurements from a plurality of Access Points (APs) may be used to determine that at least one AP in the plurality is mobile. Measurements from APs determined to be mobile may be excluded when determining a User Equipment (UE) location. Disclosed embodiments also pertain to AP mobility characterization. AP mobility may be determined based on range rate measurements such as Round Trip Time measurements between the AP and UE; or a Doppler frequency shift relative to a nominal frequency used by the AP for transmissions. Based on range rate measurements, a probability of mobility may be assigned to APs. Information pertaining to APs that are determined to be stationary or associated with a low probability of mobility may be reported to a location server. Information pertaining to APs determined to be mobile or associated with a higher probability of mobility may not be reported to a location server.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing an enhanced network scan. In one aspect, during a network scan of a first frequency band, a station (STA) may provide a probe request to an access point (AP) of a communication network via the first frequency band. The probe request may indicate the STA supports communications in both the first frequency band and a second frequency band. Based on a probe response received from the AP, the STA may determine whether the AP supports communications in both the first frequency band and the second frequency band. The STA may determine to terminate the network scan without scanning the second frequency band in response to determining that the AP supports communications in both the first frequency band and the second frequency band.

Abstract: A wireless access point enables or rejects a wireless connection request from a mobile device based on a round trip time (RTT) measurement and an angle of arrival (AoA) measurement for signals from the mobile device. After receiving a wireless connection request from the mobile device, the wireless access point obtains the RTT and the AoA measurements for the mobile device. The wireless access point determines if the RTT and the AoA measurements for the mobile device are within predefined RTT and AoA ranges that define a physical boundary with respect to the wireless access point. The wireless connection is accepted if the RTT and AOA measurements are within the predefined RTT and AoA ranges and are otherwise rejected. If desired, a plurality of physical boundaries may be used, each with different predefined RTT and AoA ranges, and each physical boundary may have a different predefined time limit range.

Abstract: A method and apparatus for establishing a direct link between wireless stations (STAs) in a wireless network, as performed by an access point (AP). The AP monitors communications routed through the AP between a first STA and a second STA in the wireless network, and determines a quality of the communications routed through the AP. The AP selectively establishes a direct link between the first STA and the second STA based at least in part on the quality of the communications routed through the AP.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless stations (STAs) may have traffic to exchange between one another. Through establishing a direct connection with another STA, communications may flow directly from one STA to the other STA, without occupying resources of the network at the access point (AP). This may make the network more efficient, as the AP may direct those unused resources to other communication needs. When establishing a direct connection between STAs, the STAs may be unable or have difficulty determining a signal strength because different signals may be based on different transmission powers. In some examples, it may be beneficial to use a ranging frame, such as a fine timing measurement (FTM) frame, for determining a signal strength between two STAs.

Abstract: Methods, systems, and apparatuses for wireless communication are described at a device. A device may utilize telescopic discovery techniques to efficiently preserve a wireless connection until a previously connected device returns within range of the connection. In one example, the device may transmit a discovery request intended for the other device according to a first interval after determining the wireless connection. If a response is not received, the device may adjust the transmission interval to be a second interval. The device may then compare the second interval with a maximum interval to determine whether the second interval is greater than the maximum interval. If the second interval is less than the maximum the device may transmit a discovery request according to the second interval. Otherwise, the device may transmit discovery requests according to the maximum interval until a discovery response is received from the other device.
