Abstract

Provided are a method and apparatus for transmitting CSI feedback information for multiple beams. The method includes: transmitting information for indicating a type of the CSI feedback information; transmitting a first type of CSI feedback information in the CSI feedback information for the multiple beams by using a first type of CSI feedback manner, wherein the first type of CSI feedback information includes at least first transmission rank information, first channel quality information and feedback information for a first beam in the multiple beams; and transmitting a second type of CSI feedback information in the CSI feedback information for the multiple beams by using a second type of CSI feedback manner, wherein the second type of CSI feedback information includes at least second transmission rank information, second channel quality information, and feedback information for beams other than the first beam in the multiple beams.
