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. The PCI to be used, a CQI indicating downlink channel quality, and ACK/NACK indicating a data decoding result are borne over an uplink HS-DPCCH. The same are fed back to a corresponding base station node to instruct the base station node to select a MIMO single-stream manner or a single-antenna manner to send data to be sent.
