    摘要: Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples communicate the CSD mode in a signaling message. Specifically, a CSD mode is set in an access point the sent to a mobile device. The signaling messages may be either a point-to-point message or a broadcast message. The access point or location server may set the current CSD mode from a plurality of mobile devices by crowd sourcing. For example, the plurality of mobile devices may report what CSD mode was detected. Alternative, the plurality of mobile devices may send a channel impulse response (CIR), or the like, to a location server and the location server may determine what CSD mode is currently used by the access point.

    摘要: Navigation assistance information for a mobile station is acquired based on a feature descriptor of an image of a visual beacon captured by the mobile station. The navigation assistance information includes locations of neighboring visual beacons, locations of wireless positioning resources; user environmental context information. The navigation assistance information may then be used to assist in navigating within the local environment. The visual beacon may be an artificial feature, such as a QR code or other type of matrix or bar code or a natural feature, such as a statute or architectural detail. The mobile station may request navigation assistance by transmitting the feature descriptor to a server. The server retrieves the navigation assistance information from a database based on the feature descriptor and optionally location information, which may also be provided in the navigation assistance request, and transmits the navigation assistance information to the mobile station.
