<p>The invention provides a method and a device for pre-coding matrix/vector in a multi-input and multi-output system. The method comprises the steps as follows: a data receiving terminal selects the pre-coding matrix index or the pre-coding vector index of a user by judging whether every data stream of the user transferred is retransmission data stream or not. After the condition that the user retransmission is needed or not is considered, pre-coding index information fed back by the user in a multi-input and multi-output pre-coding system is selected, thereby the throughput of the system is further enhanced.</p> |
