Abstract: Methods and apparatus for processing positioning data are provided. In an example, a method for processing positioning data associated with one or more access points includes choosing, for inclusion in the positioning data, one or both of: (1) ranging model parameters to enable a mobile device to compute first heatmap data for multiple points in a ranging region of a heatmap, or (2) second heatmap data for a plurality of points in a non-ranging region of the heatmap. The method can also include transmitting the positioning data, such as to a mobile device. The positioning data can also include both the ranging model parameters and the second heatmap data when the ranging region and the non-ranging region fully or partially overlap, in which case the second heatmap data provides correction data to enable the mobile device to modify the computed heatmap data in the area where the two regions overlap.

Abstract: Methods and apparatuses of providing assistance data of a venue to a mobile device are disclosed. According to aspects of the present disclosure, one approach is to compute a visibility area that may satisfy positioning criteria for a venue, for example a mobile device may observe sufficient signals for positioning in the visibility area. Then, positioning assistance data may be generated that includes the information of signal characteristics in this visibility area. With this approach, the size of the positioning assistance data can be reduced and can be used more efficiently for positioning applications without losing useful information.
