Abstract: 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.

Abstract: Disclosed are methods for positioning. An example method may include sensing, at an apparatus in a space, at least one another apparatus in the space, determining first information including a position of the at least one another apparatus relative to the apparatus, transmitting the first information to the at least one another apparatus, and receiving from the at least one another apparatus second information including a position of the apparatus relative to the at least one another apparatus. Related apparatuses, system and computer readable media are also disclosed.
