A method of wireless communication by a user equipment (UE) comprises receiving, from a base station, multiple reference signals, and estimating a channel based on the received reference signals. The channel comprises multiple channel paths. The method also includes quantizing an angle of arrival (AoA) of each channel path into one of a group of quantization levels. The method further includes reporting to the base station the quantized angle of arrival, and also a delay and/or power level for the quantized angle of arrival.
