摘要： The present invention relates to automatic repeat request (ARQ) in wireless communication systems wherein a coded message block is spread over a plurality of sub-carriers or components. According to the invention an equalizing HARQ method is introduced. The equalizing HARQ identifies (215) and retransmits (230) the most distorted parts of a received coded message block. In addition, the retransmitted parts can optionally be relocated (225) to components of higher quality, which ensures good retransmission quality for those badly distorted parts in the prior transmission. After a soft-bit combination in a receiving node, the final received codeword experience an equalized quality variation with low multi-state performance loss.

摘要： A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.
