Zusammenfassung:An apparatus comprising at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus to calculate one or more eigenvectors associated with one or more uplink reference signals. The at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to apply one or more channel hardening matrices based upon the one or more eigenvectors to one or more downlink channel state information reference signals. The at least one memory and the computer program code are further configured to, with the at least one processor, cause the apparatus to receive explicit channel state information from a user equipment.
