CHANNEL STATE INFORMATION (CSI) MEASUREMENT METHOD, TERMINAL, AND NETWORK SIDE DEVICE

This application discloses a channel state information CSI measurement method, a terminal, and a network-side device, and pertains to the field of communication technologies. The CSI measurement method of embodiments of this application includes: sending, by the network-side device, CSI measurement configuration information to the terminal, where the CSI measurement configuration information is used for configuring a target CSI measurement resource associated with measurement of target CSI information; and receiving, by the network-side device, the target CSI information from the terminal. The target CSI information includes at least one of the following: Doppler shift, Doppler spread, Doppler spectrum, time domain channel correlation matrix, delay spread, average delay, delay spectrum, and frequency domain channel correlation matrix.
