Abstract
The present disclosure provides a method and apparatus for transmitting and receiving Channel State Information. The said transmitting method includes calculating the maximum value m(k) of real part and imaginary part of each element in CSI matrix H(k) of the sub-carrier; carrying out M bit quantization to m(k) to obtain the quantization amplitude M(k); calculating the linear portion M(k) of M(k); using M(k) for carrying out Nbit quantization to real part and imaginary part of each element in H(k) respectively to obtain the quantized CSI matrix H(k); Nbeing a positive integer; and transmitting said quantization amplitude M(k) and said quantized CSI matrix H(k).
