measuring, by the terminal device, a plurality of downlink reference signals;
determining, by the terminal device, a value of a parameter using the measurement,
wherein whether a Channel State Information (CSI) report is associated with one of the plurality of the downlink reference signals or is associated with two of the plurality of the downlink reference signals, is based on the value of the parameter; and
transmitting, by the terminal device, the CSI report based on the measurement and the parameter,
wherein the CSI report comprises one precoding information in a case where the value of the parameter indicates that the CSI report is associated with one of the plurality of the downlink reference signals, and the CSI report comprises two precoding informations in a case where the value of the parameter indicates that the CSI report is associated with two of the plurality of the downlink reference signals.
