    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: A method and arrangement in a first mobile terminal (600) for determining allocation of radio resources for DMO communication amongst a group of mobile terminals. M the first mobile terminal, a first determining module 600a determines a communication (Sout, Sin) with a second mobile terminal (602) of the group. A second determining module (600b) determines a resource element (RE) for communication by applying a predefined cryptographic function P based on a terminal identification (K)). The cryptographic function has been configured in the mobile terminals of the group to provide terminal-specific resource elements for different mobile terminals within respective radio frames.
