Abstract: Embodiments of the present invention disclose a precoding control indication feedback method, a user equipment, and a base station. Channel capacity values corresponding to precoding matrices in a precoding matrix set are calculated. A sequence number of a precoding matrix corresponding to a maximum channel capacity value is used as a PCI to be used.
