<p>A wireless communication method includes a mobile terminal for supporting precoding matrix feedback for multi-user and single-user multiple-input and multiple-output (MIMO) systems. The wireless communication method also includes obtaining, at the mobile terminal, channel state information comprising at least gain information and relative-phase information. Further, the method includes generating precoding matrices comprising bg, p1, p2, and p3 bit groups, wherein each of the precoding matrices are generated by quantization using at least the gain information and the relative-phase information between antenna elements. The method also includes selecting the best precoding matrix among the generated precoding matrices, and transmitting the bit sequence representing the selected precoding matrix to a base station.</p> |
