Abstract
Provided are methods and apparatuses for measuring CSI. The method comprises: a terminal device determining whether a subframe a channel state information interference measurement resource is located on is a downlink subframe; when the subframe where the channel state information interference measurement resource is located is a downlink subframe, the terminal device executing interference measurement by using the channel state information interference measurement resource. By means of the present disclosure, the technical problem is solved that it is difficult to effectively perform the CSI measurement caused when a base station flexibly adjust uplink-downlink configuration in a related technology, thereby achieving the technical effect of improving the data transmission performance of a system.
