The invention provides a channel state information reporting method, a channel state information reporting device and user equipment. The method includes the following steps that: measurement configuration information that is sent by a network side is acquired; a transmission scheme for calculating channel state information is determined according to the measurement configuration information; codebook part information and channel quality indication information which are required to be reported are calculated according to the determined transmission scheme for calculating the channel state information; and the channel state information is reported according to the calculated codebook part information and channel quality indication information. With the channel state information reporting method, the channel state information reporting device and the user equipment provided by the present invention adopted, transmission scheme assumptions can be obtained in an NR (New Radio) system, andthe channel state information can be reported timely.
