1. A method of identifying virtual anchors performed by a network entity, comprising:
obtaining a set of data samples associated with a user equipment (UE), each data sample of the set of data samples comprising a location of the UE and a set of multipath components (MPCs) obtained by the UE at the location of the UE; and
determining whether any MPCs in a subset of non-line-of-sight (NLOS) MPCs selected from at least one set of MPCs are associated with any previously identified virtual anchors in a database of found virtual anchors,
wherein one or more first NLOS MPCs are removed from the set of data samples based on the one or more first NLOS MPCs being associated with a previously identified virtual anchor, and
wherein one or more second NLOS MPCs are added to the database of found virtual anchors based on the one or more second NLOS MPCs not being associated with any previously identified virtual anchor.
