1. A method of wireless positioning performed by a base station, the method comprising:
determining a channel profile for a multipath channel between the base station and a user equipment (UE) based on at least one positioning reference signal (1) transmitted to the UE by the base station or (2) received from the UE by the base station, wherein the at least one positioning reference signal is transmitted to the UE or received from the UE on one or more radio beams;
compressing the channel profile into a compressed representation of the channel profile; and
transmitting the compressed representation of the channel profile to a network entity to enable the network entity to determine a location of the UE.
