PRECODED INFORMATION ACQUISITION DEVICE, METHOD AND SYSTEM

WIPO Patent Application WO/2016/054809

A1

Disclosed in an embodiment of the present invention is a precoded information acquisition device, comprising: a determination module, for determining a conversion quantity according to a steering vector and a range of an angle of departure of an antenna pattern; a transmission module, for transmitting to a terminal the information of the conversion quantity determined by the determination module, the information of the conversion quantity being used by the terminal to determine a PMI according to the information of the conversion quantity, a codebook for acquiring channel information and a pilot frequency measurement result; a receiving module, for receiving the PMI reported by the terminal. A network node transmits to the terminal the conversion quantity containing antenna information, and the terminal feeds back the PMI according to the conversion quantity, such that the network node can fully and flexibly acquire the channel information to adapt to application scenarios of different antenna patterns and different angles of departure.
