A method for measuring a channel state information reference signal, CSI-RS, performed by a terminal device, the method comprising: • receiving, from a network device, a notification, the notification being used to notify the terminal device of at least one CSI-RS resource set for channel measurements configured by the network device and at least one CSI-RS resource set for interference measurements configured by the network device, o wherein each CSI-RS resource set among the at least one CSI-RS resource set for channel measurements consists of resources used for channel measurements and includes non-zero power CSI-RS resources, and each CSI-RS resource set among the at least one CSI-RS resource set for interference measurements consists of resources used for interference measurements and includes at least one of a zero power CSI-RS resource and a non-zero power CSI-RS resource; • receiving (step 101) an indication from the network device, the indication containing: o first indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for channel measurements, to the terminal device, o second indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for interference measurements, to the terminal device, and o third indication information indicating a channel state information reporting setting identifier, CSI reporting setting ID to the terminal device; • performing (step 103) a channel measurement based on the received first indication information and performing an interference measurement based on the second indication information, and sending a CSI report back to the network device based on the CSI reporting setting ID, wherein the CSI report contains a result of the performed channel measurement and the performed interference measurement. • receiving, from a network device, a notification, the notification being used to notify the terminal device of at least one CSI-RS resource set for channel measurements configured by the network device and at least one CSI-RS resource set for interference measurements configured by the network device, o wherein each CSI-RS resource set among the at least one CSI-RS resource set for channel measurements consists of resources used for channel measurements and includes non-zero power CSI-RS resources, and each CSI-RS resource set among the at least one CSI-RS resource set for interference measurements consists of resources used for interference measurements and includes at least one of a zero power CSI-RS resource and a non-zero power CSI-RS resource; • receiving (step 101) an indication from the network device, the indication containing: o first indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for channel measurements, to the terminal device, o second indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for interference measurements, to the terminal device, and o third indication information indicating a channel state information reporting setting identifier, CSI reporting setting ID to the terminal device; o first indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for channel measurements, to the terminal device, o second indication information indicating a CSI-RS resource set, among the at least one CSI-RS resource set for interference measurements, to the terminal device, and o third indication information indicating a channel state information reporting setting identifier, CSI reporting setting ID to the terminal device; • performing (step 103) a channel measurement based on the received first indication information and performing an interference measurement based on the second indication information, and sending a CSI report back to the network device based on the CSI reporting setting ID, wherein the CSI report contains a result of the performed channel measurement and the performed interference measurement.
