METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING ACK/NACK SIGNAL TO SUPPORT HYBRID AUTOMATIC REPEAT REQUEST FOR MULTI-LAYER TRANSMISSION |
摘要 |
A method and apparatus for transmitting an Acknowledge (ACK)/Non-Acknowledge (NACK) signal to support Hybrid Automatic Repeat reQuest (H-ARQ) in an Orthogonal Frequency Division Multiplexing (OFDM) system are provided. A controller selects one of a plurality of Discrete Fourier Transform (DFT) input positions mapped to data channels over which a received data stream is transmitted in a group corresponding to a layer over which the received data stream is transmitted. The plurality of input positions is grouped into N groups for N layers for transmitting different data streams, and the input positions in each group are mapped to different data channels. A transmission module transmits an ACK/NACK signal for the received data stream over the DFT input position selected by the controller.
