    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.

    Abstract: A method for acquiring uplink grant information, UE, and a base station are provided, where the method includes: obtaining, by UE, configuration signaling that includes a code channel number of a downlink control channel, and monitoring, on at least one code channel of the downlink control channel according to the configuration signaling, a channel that bears uplink grant information. During implementation of HSUPA by applying embodiments of the present invention, code channel resources of a downlink control channel that are supported by the UE are more than code channel resources of an uplink control channel; therefore, when a channel that bears uplink grant information is sent by using a code channel resource of the downlink control channel, flexibility of scheduling the UE by a system can be increased, and overheads of downlink code channel resources can also be reduced.
