摘要： The present disclosure provides a method for notifying an interference measurement signalling, including that: notifying, by a network side, information of M subframes included in an interference measurement subframe set or a channel quality measurement subframe set to a terminal. The present disclosure also provides a method for measuring interference, including that: receiving, by a terminal, a notification of information of an interference measurement subframe set or a quality measurement subframe set sent by a network side, performing interference measurement on each subframe of the interference measurement subframe set or the channel quality measurement subframe set, and calculating an average interference value; and determining, by the terminal, Channel Quality Indication (CQI) information according to the average interference value, and feeding the CQI information back to a base station. The present disclosure further provides a method for feeding back channel quality information, including that: performing, by a terminal, interference measurement on one or more subframes specified by a base station, determining a CQI according to the measurement result, and feeding back the CQI to the base station. The present disclosure also provides devices for implementing above methods. In the present disclosure, the base station can accurately determine a modulation and coding scheme of the terminal according to the interference measurement result, thus improving data transmission efficiency.
