Method and device for determining indication signalling of pilot signal for channel measurement and method and device for feeding back csi

A method for determining indication signalling of a pilot signal for channel measurement, comprising:

• receiving, by a terminal, Downlink (DL) control signalling, which comprises transmission resource configuration information of non-periodic Channel State Information Reference Signal (CSI-RS), from a NodeB, wherein the transmission resource configuration information of the non-periodic CSI-RS is used for determining a location of the non-periodic CSI-RS,
• wherein the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Downlink Shared Channel (PDSCH) are received from the NodeB by the terminal in the same Downlink Control Information (DCI) format of the DL control signalling;
• or,
• the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Uplink Shared Channel (PUSCH) are received from the NodeB by the terminal in the same DCI format of the DL control signalling.

A device for determining indication signalling of a pilot signal for channel measurement, which is applied to a NodeB and comprises:

• a first sending component, configured to send 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,
• wherein the first sending component is configured to:
• send the transmission resource configuration information of the non-periodic CSI-RS and resource allocation information of a Physical Downlink Shared Channel (PDSCH) to the terminal in the same Downlink Control Information (DCI) format of the DL control signalling;
• or,
• send 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 DCI format of the DL control signalling.
