1. A method for reporting beams of interest for positioning measurements, comprising: receiving, at a user equipment (UE) from a base station, a plurality of beams, wherein receiving the plurality of beams comprises detecting one or more channel taps corresponding to each of the plurality of beams; determining, by the UE, a time of arrival of each beam of the plurality of beams; identifying, by the UE from the plurality of beams, one or more beams of interest for determining a positioning measurement of the base station based on the times of arrival of the plurality of beams; sending, by the UE to the base station, a report including identifiers of each of the one or more beams of interest; and receiving, at the UE from the base station, based on the report identifying each of the one or more beams of interest, at least one beam carrying positioning reference signals for the base station in a same direction as a direction of the one or more beams of interest.
