1. A method for wireless communications at a user equipment (UE), comprising:
measuring, at the UE, a reference signal from a network entity using two or more beamforming parameters for two or more antennas to identify at least a first narrow beam with a beamforming gain that exceeds beamforming gains of one or more other narrow beams, wherein the first narrow beam has a first beam direction and a first beam width;
determining, at the UE, a second beam direction and a second beam width for a first wide beam, wherein the second beam direction is based at least in part on the first beam direction and the second beam width is a multiple of the first beam width and based at least in part on the first beam width; and
transmitting a set of wide beam parameters to the network entity that indicate the second beam direction and the second beam width of the first wide beam.
