PROBLEM TO BE SOLVED: To provide an efficient feedback mechanism to enable closed-loop MIMO operation.SOLUTION: To execute radio communication in a closed-loop MIMO (multiple input, multiple output) system, a feedback data structure is communicated between a first radio node and a second radio node through a radio channel. The feedback data structure includes an indicator to identify coding applied to the second radio node, related to a signal communicated between the second radio node and the first radio node. The information of the feedback data structure is based on a radio channel state detected in the first radio node. The indicator identifies different coding used for a corresponding band of a different radio channel. |
