Abstract

A method to use RSs for per-user elevation beamforming is described. An eNB sends, to a UE, an indication of which RSs in a plurality of RSs sound in the elevation dimension and which RSs in the plurality of RSs sound in the azimuthal dimension. Then, the eNB sends, to the UE, the plurality of RSs using a plurality of antenna. The UE separates the plurality of RSs into the first portion and the second portion based at least in part on the indication and sends elevation and azimuthal feedback based on the received RSs to the eNB. The eNB determines beamforming weights for the plurality of antenna based at least in part on the elevation feedback and the azimuthal feedback. Apparatus and computer readable media are also described.
