Abstract:
A method for retransmitting signals in a MIMO system that uses an HARQ scheme is provided. In the method, an additional codeword-to-layer mapping scheme for retransmission in a MIMO system that uses an HARQ scheme is defined and used to efficiently retransmit signals. In addition, required information is obtained using existing control information to more efficiently retransmit signals in terms of control signal overhead.
