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. |
