Apparatus and methods for apparatus positioning are provided. Solution includes receiving (300) by an apparatus from a network element a signal having multipath propagated signal components and obtaining time domain samples of the multipath propagated signal components, mapping (302) the time domain samples to one or more frequency offset-delay pairs to obtain frequency offsets and delays of the received multipath propagated signal components, calculating (304) angle of arrival of one or more multipath propagated signal components, determining (306) the multipath propagated signal component corresponding to the direct propagation path between the apparatus and the network element, and controlling (308) the utilisation of the angle of arrival and delay of the multipath propagated signal component corresponding to the direct propagation path in the determination of the location of the apparatus.
Offline Radio Maps for Device-Specific GNSS Rescue Areas
Disclosed is an approach to enable optimized GNSS augmentation via learning at a mobile device. In particular, the mobile device could identify device-specific GNSS rescue area(s), the device-specific GNSS rescue area(s) corresponding to geographic area(s) visited by the mobile device in which (i) at least one GNSS-based position estimate is or was unavailable and (ii) the mobile device had demand for positioning data of at least a particular quality level. The mobile device could then receive, from positioning server(s), an offline radio map representing radio data only for the device-specific GNSS rescue area(s), and could store the offline radio map in a local data storage device. In turn, the mobile device could perform position estimation(s) using the offline radio map representing radio data only for the device-specific GNSS rescue area(s).
System and method for determining a location area of a mobile user
Systems and methods are provided for determining location area of mobile user devices. In a mobile device, a first area probability as a likelihood that the mobile device is located within a first area and a second area probability indicative of the mobile device being located within a second area may be determined, with the first area probability determined based on a first probability and a second probability, and the second area probability determined based on a third probability and a fourth probability. The first probability, second probability, third probability, and fourth probability are determined based on assessing strength received in the respective area from a first base station or a second base station. A determination of whether the mobile device is located in the first area or the second area is made based on the first area probability and the second area probability.
