摘要： The present invention relates to methods and arrangements in a multi-antenna radio communication system, in particular to methods and arrangements for improved multiple HARQ transmission in such systems. While HARQ transmission schemes, as known in the art, only can consider the fact whether or not a transmission attempt has been successful the present invention provides a HARQ retransmission scheme that considers the reception quality for already performed transmissions of a same data packet when selecting a resource allocation for necessary re-transmissions. Resource allocation for retransmissions is based on a pre-defined metric indicating a quality of the reception of the previous transmission attempts. Such a metric can be derived from a quality measure derived in the receiver unit, e.g. a CQI or CSI-based value, or an appropriate measure of the mutual information, e.g. the accumulated conditional mutual information (ACMI) .
摘要翻译：本发明涉及多天线无线电通信系统中的方法和装置，特别涉及用于改进这种系统中的多个HARQ传输的方法和装置。尽管本领域已知的HARQ传输方案只能考虑传输尝试是否成功的事实，但是本发明提供了一种HARQ重传方案，其在选择一个或多个节点时考虑已经执行的相同数据分组的传输的接收质量资源分配进行必要的重新传输。用于重传的资源分配基于指示先前传输尝试的接收质量的预定义度量。这样的度量可以从在接收机单元中导出的质量度量导出，例如，基于CQI或基于CSI的值，或相互信息的适当度量，例如。累积条件互信息（ACMI）。
