摘要： The present invention relates to methods and arrangements that enable easy integration of on/off repeaters in a radio access network and a minimized signaling for the UE repeater selection. This is achieved by a solution where the RBSs are working in a pre- coding mode and where the repeaters are measuring the downlink reference signals, selecting pre-coding matrices and feeding the index of selection back (i.e. the PMI) to the RBS, in analogy with what a UE does. This allows the RBS to distinguish the UE repeater selection, without introducing any extra uplink report or interaction between UEs and repeaters, by comparing the index from the UE with the indices from different repeaters.
摘要翻译：本发明涉及能够容易地集成无线电接入网络中的开/关转发器和用于UE中继器选择的最小化信令的方法和装置。这通过解决方案实现，其中RBS以预编码模式工作，并且其中中继器正在测量下行链路参考信号，选择预编码矩阵并将选择指数返回（即，PMI）到RBS，在类似于UE所做的工作。这允许RBS通过将来自UE的索引与来自不同中继器的索引进行比较来区分UE中继器选择，而不引入任何额外的上行链路报告或UE与中继器之间的交互。

摘要： The disclosure relates to methods and apparatuses that allow for channelisation code allocation adapted for uplink MIMO transmissions. A method for use in a user equipment of a telecommunication system comprises spreading data symbols of a plurality of streams to be transmitted from the user equipment as MIMO transmissions. The step of spreading the data symbols comprises allocating, for each stream, at least one channelisation code (62) to be applied for spreading the data symbols of the stream. The plurality of streams are allocated channelisation codes (62) from a predefined code tree (61) of applicable channelisation codes such that any channelisation code (62) is allocated to more than one stream only if there is no applicable channelisation code left in the code tree (61) which currently is not allocated for any stream. The channelisation code allocation scheme makes it possible to avoid inter- stream interference in many scenarios of uplink MIMO transmissions.
