Methods and apparatuses for measuring CSI
First Claim
1. A method for measuring channel state information (CSI), comprising:
- a terminal device receiving configuration information from a network side device, wherein the configuration information is used for indicating channel state information interference measurement resources configured for multiple subframe groups by the network side device, and each subframe group in the multiple subframe groups comprises one or more subframes;
the terminal device receiving at least one of the following first information from the network side device;
uplink-downlink configuration information, downlink control information (DCI);
the terminal device determining a subframe where a channel state information interference measurement resource is located is a downlink subframe, according to the configuration information and the first information;
the terminal device executing interference measurement by using the channel state information interference measurement resource within the downlink subframe.

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.
