摘要： One method for controlling operation of a repeater in radio communication system comprises determination whether operation of a node in the radio communication system benefits from assistance of a repeater and transmitting, from the node in the radio communication system, a radio signal to the repeater being indicative of an order to promptly activate the repeater if the benefit exists. One complementary method for controlling operation of a repeater in radio communication system comprises detection (252), in the repeater, of a radio signal being indicative of an order to activate the repeater. Amplification in the repeater is activated (254) as a response to such a detected radio signal and uplink traffic from a user terminal being located in a vicinity of the repeater and/ or downlink traffic to the user terminal is amplified (256). A repeater, a node, a user terminal and a system operating according to the method are presented.

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）。

摘要： 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.
摘要翻译：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。
