Abstract:
Provided are a method, apparatus and system for acquiring a codebook, the method including: generating, by a base station, a codebook corresponding to N t  ports and r layers transmission according to a first preset condition, the codebook being for feeding back a preceding matrix, the first preset condition being a common set condition between the base station and a terminal, N t  being a port number, and r being a transmission layer number; determining, by the base station, a signaling indication method for selecting a codebook subset corresponding to the codebook according to a second preset condition; and acquiring, by the base station, Codebook Subset Selection (CSS) signaling for selecting the codebook subset correspondingly according to the signaling indication method, and notifying the selected codebook subset to a terminal through the CSS signaling.

Claim (Index 45):
An apparatus for acquiring a codebook, comprising:\n a processor; and a memory for storing instructions executable by the processor; wherein the processor is configured to: generate a main codebook corresponding to N t  ports and r layers transmission according to a first preset condition, the codebook being for feeding back a precoding matrix, the first preset condition being a common set condition between a base station and a terminal; generate a codeword set corresponding to the codebook according to a sixth preset condition and the main codebook; and configure the codebook according to a notification, the notification comprising at least one of: selection information of the codeword set, and selection information of codewords in the codeword set.
