摘要：
A technique is provided for receiving, by a user device from a base station, a first reference signal via a plurality of base station transmit beams; selecting, based on the first reference signal received via the plurality of transmit beams, beam indices for a subset of correlation coefficients to be reported to the base station; receiving, by the user device from the base station, a second reference signal via a plurality of the transmit beams; determining, based on the selected beam indices, the subset of correlation coefficients of a correlation matrix based on the second reference signal received via each of the plurality of transmit beams; and reporting, by the user device to the base station, the subset of correlation coefficients.
