1. A method for wireless communication at a device, comprising:
receiving, from a second device, control signaling comprising an indication of a set of measurement beams for beamformed communication in accordance with the set of measurement beams satisfying a condition, the set of measurement beams being one of a plurality of sets of measurement beams;
selecting a subset of measurement beams from the set of measurement beams, wherein the selected subset of measurement beams is selected in accordance with a number of measurement beams of the selected subset of measurement beams being less than a number of elements of a channel covariance matrix, and wherein the number of measurement beams is less than a total number of measurement beams of the set of measurement beams;
determining a subset of elements of the channel covariance matrix based at least in part on signal strength or phase measurements associated with the selected subset of measurement beams;
determining remaining elements of the channel covariance matrix based at least in part on one or more approximations using the determined subset of elements of the channel covariance matrix; and
performing the beamformed communication via a set of estimated beam weights for communication, wherein the set of estimated beam weights is based at least in part on the channel covariance matrix.
