Disclosed are a channel information feedback method, and a pilot and beam transmission method, system and device. The channel information feedback method comprises: transmitting, by a base station, M types of pilot signals, wherein the M types of pilot signals respectively correspond to M pilot ports; configuring, by the base station, N pilot ports from the M pilot ports to a terminal through signalling, where M is a positive integer, and N is a positive integer less than M; receiving and detecting, by the terminal, pilot signals of the N pilot ports; and according to the quality of the received signals, selecting K pilot ports from the N pilot ports, and feeding back channel information about a channel formed by the K pilot ports and the terminal, where K is a positive integer less than N. |
