摘要： Provided is a method for retransmitting packet in a Multiple Input Multiple Output (MIMO) system. The method includes: in a receiving block, decoding packets received from a transmitting block and detecting whether an error exists or not in the packets; if the error is detected, transmitting a negative acknowledgement (NACK) signal informing transmission failure of the packets to the transmitting block; calculating channel quality information (CQI) values for transmission-failed packets after performing successive interference cancellation (SIC) with respect to all antenna combinations to retransmit the transmission-failed packets; and selecting an antenna combination having CQI values of the transmission-failed packets which are equal to or greater than respective initial CQI values of the transmission-failed packets among the antenna combinations, and transmitting information of the selected antenna combination to the transmitting block.

摘要： The present invention relates a method and apparatus for transmitting/receiving data using multiple codewords in a communication system using SC-FDMA (single carrier frequency division multiple access). A transmitter generates the multiple codewords for user data and transmits the generated multiple codewords. A receiver receives the multiple codewords and sequentially performs decoding and SIC (successive interference cancellation) on the received multiple codewords. Therefore, this structure can minimize a PAPR (peak to average power ratio) and considerably reduces interference between symbols in a frequency selective fading environment.
