1. A method of operating a user equipment (UE), comprising:
receiving location assistance data that comprises information that indicates a line of sight (LOS) condition associated with a first propagation path between a wireless network node and the UE, wherein the first propagation path is associated with an identifier of one or more resources of a reference signal for positioning (RS-P), and wherein the first propagation path is one of a plurality of paths between the wireless network node and the UE and the LOS condition is specifically indicated for the first propagation path; and
determining a location estimate of the UE based in part on one or more positioning measurements associated with the RS-P on the first propagation path and the indicated LOS condition, wherein the one or more measurements associated with the RS-P are performed after the location assistance data is received,
wherein the indicated LOS condition indicates a probability or confidence level of the first propagation path being a LOS propagation path.
