Abstract
The present disclosure provides a method and apparatus for transmitting the beamforming matrix. The method includes calculating the maximum value mv(k) of the real part and imaginary part of the elements in subcarrier's beamforming matrix; carrying out a M bits quantization to mv(k) and obtaining the quantization amplitude Mv(k), calculating the linear part Mvlin(k) of Mv(k); carrying out a respectively Nb bits quantization to the real part and imaginary part of every element in V(k) by Mvlin(k), and obtaining the quantized beamforming matrix Vq(k); Nb is positive integer; transmitting said quantization amplitude Mv(k) and said quantized beamforming matrix Vq(k).
