A method for beam reporting, applied in a New Radio, NR, system, comprising: using, by a terminal device, reference signal resources in a configured first set for channel measurement for a beam and reference signal resources in a configured second set for interference measurement for the beam; wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set; and calculating and reporting, by the terminal device, Signal-to-Interference and Noise Ratio, SINR, based on results of the channel measurement and the interference measurement; wherein the reference signal resources in the first set are Channel State Information - Reference Signal, CSI-RS, resources and/or Synchronization Signal, SSZ Physical Broadcast Channel, PBCH, resources, the reference signal resources in the second set are CSI-RS resources and/or Non-Zero-Power, NZP, CSI-RS and/or Channel State Information - Interference Measurement, CSI-IM, resources; wherein when QCL-Type D configuration is configured to the CSI-RS resource or SS/PBCH block in the first set, the terminal device receives associated CSI-RS resource in the second set for interference measurement by taking that the associated CSI-RS resource is quasi co-located to a Reference Signal, RS, which is the RS with QCL-Type D configuration in a Transmission Configuration Index, TCI, state configured to the CSI-RS resource in the first set or the RS with respect to QCL configuration for the SS/PBCH block in the first set; wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set in the following way: the reference signal resources in the first set and the reference signal resources in the second set are configured in sequence; a reference signal resource in the first set is associated with one or more reference signal resources in the second set according to a position of the reference signal resource in the first set and positions of the one or more reference signal resources in the second set. using, by a terminal device, reference signal resources in a configured first set for channel measurement for a beam and reference signal resources in a configured second set for interference measurement for the beam; wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set; and calculating and reporting, by the terminal device, Signal-to-Interference and Noise Ratio, SINR, based on results of the channel measurement and the interference measurement; wherein the reference signal resources in the first set are Channel State Information - Reference Signal, CSI-RS, resources and/or Synchronization Signal, SSZ Physical Broadcast Channel, PBCH, resources, the reference signal resources in the second set are CSI-RS resources and/or Non-Zero-Power, NZP, CSI-RS and/or Channel State Information - Interference Measurement, CSI-IM, resources; wherein when QCL-Type D configuration is configured to the CSI-RS resource or SS/PBCH block in the first set, the terminal device receives associated CSI-RS resource in the second set for interference measurement by taking that the associated CSI-RS resource is quasi co-located to a Reference Signal, RS, which is the RS with QCL-Type D configuration in a Transmission Configuration Index, TCI, state configured to the CSI-RS resource in the first set or the RS with respect to QCL configuration for the SS/PBCH block in the first set; wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set in the following way: the reference signal resources in the first set and the reference signal resources in the second set are configured in sequence; a reference signal resource in the first set is associated with one or more reference signal resources in the second set according to a position of the reference signal resource in the first set and positions of the one or more reference signal resources in the second set.
