摘要： Methods, apparatuses, and devices are disclosed to estimate a position of a mobile device using, for example, beacon signals transmitted using virtual access points utilizing a single, physical transceiver. Determination that beacon signals emanate from a single, physical transceiver may be based, at least in part, on a similarity among acquired beacon signals conveying identifiers, such as media access control identification (MAC ID) addresses and/or basic service set identifiers (BSSIDs), and on measurement of beacon signal characteristics, such as received signal strength at a mobile device and/or round trip time between the mobile device and the transceiver.

摘要： Methods for mobility indication of wireless Access Points (APs) are disclosed. An AP may determine mobility indication information, based, in part, on at least one of: configuration information on the AP pertaining to mobility; and/or wireless signal measurements associated with the AP, and/or captured images associated with the AP, and/or sensor measurements associated with the AP. The AP may transmit the mobility indication information for the AP. The mobility indication information may indicate that the AP is mobile and/or characterize the mobility. The mobility indication information may further include a request to remove information associated with the AP from location determination databases, location assistance databases, and/or base station almanacs. Disclosed methods also pertain to a User Equipments (UE), which may receive wireless signals with mobility indication information associated with an AP; and determine a suitability of the AP for determining the UEs location based on the received mobility indication information.

摘要： Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.
