METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION

摘要

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 H ( k ) of real part and imaginary part of each element in CSI matrix H eff ( k ) of the sub-carrier; carrying out M bit quantization to m H ( k ) to obtain the quantization amplitude M H ( k ) ;calculating the linear portion M H lin k of M H ( k );using M H lin k for carrying out N b bit quantization to real part and imaginary part of each element in H eff ( k ) respectively to obtain the quantized CSI matrix H eff ( k ); N b being a positive integer; and transmitting said quantization amplitude M H (k) and said quantized CSI matrix H eff q k .
