Abstract:
A method and a radio access device for performing the method for positioning of a target station (STA) by a radio access device. The method receives sounding feedback, from a target station (STA), for each of a plurality of subbands in response to sending a sounding signal, the sounding feedback comprising channel quality information for each subband of the plurality of subbands. The method calculates an angle-of-arrival (AoA) characteristic from the sounding feedback for at least a subset of the plurality of subbands and maps the AoA characteristics of the at least the subset of the plurality of subbands to a fingerprint in a fingerprint reference map. The method then determines the location of the target STA based on at least the fingerprint.
