1. A method comprising:
obtaining elevation angle information for a plurality of user devices, wherein the elevation angle information includes, for each of the plurality of user devices, a best or preferred beam elevation angle used by a network node for communication with the user device;
estimating an elevation angle distribution for the plurality of user devices based on the elevation angle information;
determining, based on the elevation angle distribution, a set of analog beamforming weights to be used for hybrid beamforming, wherein each analog beamforming weight of the set of analog beamforming weights is associated with an analog elevation angle; and
adjusting the set of analog beamforming weights based on at least one of a set of pre-tilt angle beamforming weights or an estimated mechanical downtilt angle.
