Codebook configuration method and user equipment
The present invention provides a codebook configuration method and user equipment. The UE receives a reference signal that is of an antenna whose quantity of antenna ports is X and that is sent by a base station and configuration information of a codebook subset restriction for the quantity X of antenna ports, where the configuration information of the codebook subset restriction for the quantity X of antenna ports includes first configuration information and second configuration information; determines, according to the configuration information of the codebook subset restriction for the quantity X of antenna ports, a precoding matrix on which channel measurement and feedback need to be performed; and obtains, by means of measurement according to the reference signal, the precoding matrix on which channel measurement and feedback need to be performed and that is of antenna ports.
