Abstract
Techniques for wireless communication are described. A device may generate a channel covariance matrix using a quantity of beams that is less than a quantity of elements of the channel covariance matrix. The device may utilize a scheme for selecting a subset of beams for generating the channel covariance matrix. The device may generate one or more diagonal elements of the channel covariance matrix based on measurements of a first number of beams of the subset. The device may generate other elements of the channel covariance matrix based on measurements of a second number of beams of the subset. The device may also approximate one or more remaining elements of the channel covariance matrix based on the generated elements. The device may determine a set of beams for selecting the subset of beams, and may communicate beamformed signaling via a beam that is based on the generated channel covariance matrix.
