Feedback?
The first paragraph says "CSI needs to be estimated at the receiver and usually quantized and feedback to the transmitter..." In addition to the sentence having bad grammar construction, Channel Estimation typically does NOT include any "feedback" to the transmitter.

The next sentence is poorly constructed as well: "The method is called Channel estimation." What method? CSI is a piece of information, and Channel Estimation is a method used to characterize a channel.
