A method for determining indication signalling of a pilot signal for channel measurement, comprising: sending, by a NodeB, Downlink, DL, control signalling, which comprises transmission resource configuration information of non-periodic Channel State Information Reference Signal, CSI-RS, to a terminal, wherein the transmission resource configuration information of the non-periodic CSI-RS is used for determining a location of the non-periodic CSI-RS, and the non-periodic CSI-RS is used for instructing the terminal to perform channel measurement, wherein sending, by the NodeB, the DL control signalling, which comprises the transmission resource configuration information of the non-periodic CSI-RS, to the terminal comprises: sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a PDSCH to the terminal in the same control signalling format of the DL control signalling; or, sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Uplink Shared Channel, PUSCH, to the terminal in the same control signalling format of the DL control signalling; wherein when DL Grant of the DL control signalling triggers CSI feedback, the terminal feeds back a CSI on an Nth subframe after the DL Grant triggers the CSI feedback, wherein N is a natural number more than or equal to 1, and a value of N is a fixed integer or configured by high-layer signalling. sending, by a NodeB, Downlink, DL, control signalling, which comprises transmission resource configuration information of non-periodic Channel State Information Reference Signal, CSI-RS, to a terminal, wherein the transmission resource configuration information of the non-periodic CSI-RS is used for determining a location of the non-periodic CSI-RS, and the non-periodic CSI-RS is used for instructing the terminal to perform channel measurement, wherein sending, by the NodeB, the DL control signalling, which comprises the transmission resource configuration information of the non-periodic CSI-RS, to the terminal comprises: sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a PDSCH to the terminal in the same control signalling format of the DL control signalling; or, sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Uplink Shared Channel, PUSCH, to the terminal in the same control signalling format of the DL control signalling; sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a PDSCH to the terminal in the same control signalling format of the DL control signalling; or, sending, by the NodeB, the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Uplink Shared Channel, PUSCH, to the terminal in the same control signalling format of the DL control signalling; wherein when DL Grant of the DL control signalling triggers CSI feedback, the terminal feeds back a CSI on an Nth subframe after the DL Grant triggers the CSI feedback, wherein N is a natural number more than or equal to 1, and a value of N is a fixed integer or configured by high-layer signalling.
