摘要： There is provided a method comprising receiving at least one measured signal characteristic from a user equipment, the user equipment being located at a user equipment location; comparing the at least one measured signal characteristic to at least one of a plurality of signal characteristics, each signal characteristic being associated with a respective measurement point; and determining, based on the comparing, a probability that the user equipment location is a first location.

摘要： Methods and apparatus for sensor selection for localization and tracking are provided. A method (300) performed at an access point (101, 101a, 101b, 101c, 901, 902, 903) comprises: determining, a detectability of the access point (101, 101a, 101b, 101c, 901, 902, 903) for localization for a target device (102), based on channel state information of a radio link between the target device (102) and the access point (101, 101a, 101b, 101c, 901, 902, 903) (302); and determining whether the access point (101, 101a, 101b, 101c, 901, 902, 903) is to be used for position estimation of the target device (102) or not based on the detectability (304). A localization server (103) may further eliminate access points (101, 101a, 101b, 101c, 901, 902, 903) at poor positions from position estimation, by using a predefined weighted-kernel approach.
