    • 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) .

    • A method for allocating power and channels to connections in a multi-channel access based wireless communication system in which each connection is acting independently of the other. The quality of each channel of a connection is measured at successive time steps (n, n+1). The measurements from a previous time step (n) are used to allocate, in the following time step (n+1), an average power of all channels the connection uses as well as individual power settings in-between said channels. The average power is controlled using an outer fairness loop balancing the average channel power against average bit rate per channel. The individual power settings is controlled using an inner capacity loop allocating much power to good channels and restricted power to poor channels. Each loop has a respective target relation and the results of the loops are combined in order to determine transmission power in the next time step. The method is of distributed character and may execute on individual receiving nodes. Further, it may be applied in the up link or in the down link. The invention also relates to transmitting and receiving nodes provided with means for executing the method.
    • 一种用于在基于多信道接入的无线通信系统中的连接上分配功率和信道的方法,其中每个连接独立于另一个。 在连续的时间步长(n,n + 1)测量连接的每个通道的质量。 来自先前时间步长(n)的测量值用于在随后的时间步长(n + 1)中分配所述连接使用的所有通道的平均功率以及所述通道之间的各个功率设置。 平均功率使用平衡通道功率与每个通道的平均位速率平衡的外部公平环来控制。 使用内部容量环路控制各个功率设置,为良好的通道分配大量功率,并将功率限制在较差的通道。 每个循环具有各自的目标关系,并且组合循环的结果以便在下一个时间步长中确定发射功率。 该方法具有分布式特征,可以在各个接收节点上执行。 此外,它可以应用于上行链路或下行链路。 本发明还涉及提供有用于执行该方法的装置的发送和接收节点。
