Signaling interference measurement, interference measurement and a feedback method and apparatus

The present invention discloses a method for interference measurement notification signaling, comprising: a network-side interference measurement subframe set or terminal information notification M subframes channel quality measurement subframe set included. The present invention also discloses a method for measuring interference, comprising: the sub-interference measurement terminal receives the network side sending a frame set or a channel quality measurement subframe set notification information, the sub-interference measurement subframe set or a channel quality measurement subframe each set of sub-frames of the interference measurement, calculating an average interference value; terminal determines the interference based on the average value of the CQI information, and to the base station. The present invention also discloses a method for feedback of channel quality information, comprising: a terminal to measure interference on the base station designated subframes, determine CQI based on the measurement result, the CQI to the base station. The present invention also discloses an apparatus for realizing the method. In the present invention, the base station can be accurately determined modulation and coding scheme based on interference measurement results of the terminal, thereby improving data transmission efficiency.
