Abstract
A method and a device for transmitting and receiving channel state information in a wireless communication system are disclosed. A method for transmitting channel state information (CSI) according to one embodiment of the present disclosure may comprise the steps of: receiving configuration information related to CSI from a base station; receiving a CSI-reference signal (CSI-RS) on one or more CSI resources from the base station; and transmitting the CSI to the base station on the basis of the configuration information. The CSI may include a precoding matrix indicator (PMI) corresponding to indexes of a codebook for indicating a precoding matrix, and the PMI may include one or more amplitude coefficient indicators for indicating an amplitude coefficient and/or one or more phase coefficient indicators for indicating one or more phase coefficients.
