A method for feeding back information includes: measuring a CQI of a link between each coordinated transmitting node in a coordinated transmitting node set and a terminal; using the CQI of and an RI value corresponding to the link between each coordinated transmitting node and the terminal as parameters of a spectral efficiency calculation function, and obtaining a spectral efficiency value corresponding to the link between each coordinated transmitting node and the terminal; when a value of the selection criterion function is less than or equal to a preconfigured comparison threshold value, selecting a corresponding coordinated transmitting node as a preferred coordinated transmitting node; and sending information of the preferred coordinated transmitting node to a transmitting end for selection. This may reduce uplink feedback overheads and enable the transmitting end to quickly determine the preferred coordinated transmitting node.
