Abstract: A CSI measurement method, a CSI acquisition method, a terminal and a network device are provided, to measure CSI. The terminal performs interference measurement to acquire initial interference measurement result, determine the CSI based on the initial interference measurement result and an interference measurement parameter configured by the network device, and then report the determined CSI to the network device. The interference measurement parameter is configured by the network device, so the interference measurement parameter configured by the network device is capable of reflecting an actual situation of interference information, and interference information acquired by the terminal based on the interference measurement parameter matches interference information for actual transmission in a better manner. As a result, it is able to improve a matching degree between the interference information acquired by the terminal and the interference information for the actual transmission, thereby to enable a network to select a more appropriate parameter for link adaptation.
