Abstract
Provided are a method and device for determining indication signalling of a pilot signal for channel measurement, and method and device for feeding back CSI. The method for determining indication signalling of pilot signal for channel measurement includes: a NodeB sends DL control signalling, which includes transmission resource configuration information of a non-periodic 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. The non-periodic CSI-RS is determined according to the transmission resource configuration information of the non-periodic CSI-RS, and channel measurement is further performed according to the non-periodic CSI-RS, so that the problems of higher overhead and resource waste caused by periodical sending of a CSI-RS in the related art may be solved, resources are saved, and sending overhead is reduced.
