Bandwidth based and/or scenario based feature selection for high line-of-sight/non-line-of-sight classification accuracy

Abstract

A method performing by an apparatus, including: receiving (), from a network entity or transmitting to a user device, one or more feature set lists each including a plurality of feature sets possibly in a priority order or rank order associated with the apparatus or the user device, wherein the one or more feature set lists are based on at least one of the following: one or more bandwidth parts configured for the apparatus or the user device, one or more bandwidth capabilities of the apparatus or the user device, or one or more radio environment scenarios; and classifying or selecting channel measurements of the one or more received signals per measurement by the apparatus or by the user device, to estimate a likelihood of a propagation condition classification including one of: line-of-sight (LOS), non-line-of-sight (NLOS) and obstructed line-of-sight, based on the feature sets to determine positioning of the apparatus or the user device.
