    摘要: A method, apparatus, and computer program for continuing transmission during handover are presented. A communication connection is established between a source base station and a mobile relay base station comprising a distributed antenna system (DAS). The DAS includes multiple spatially distributed antenna units (DAUs), wherein at least part of the DAUs are used for forming a cluster of sub-cells within a coverage area of the mobile relay base station and at least part of the DAUs are used for communicating with a fixed cellular network infrastructure over multiple backhaul links. A first backhaul link is then handed over from the source base station to a target base station. After the handover, data transfer between the source base station and at least one backhaul link still linked to the source base station is continued, and remaining backhaul link(s) are released from the source base station according to a determined criterion.

    摘要: The invention relates to apparatuses, methods, a system, computer programs, computer program products and computer-readable media. Matched-filtered samples are conveyed instead of antenna samples, so that data rates in the interface between a remote radio head and the BTS or base band hotel may be lower. For detecting data, the matched filtered data samples are processed by using information on the radio channel.

    摘要: The modulator has an input (30) which receives data to be modulated. A plurality of memory regions acting as look-up tables (38-44) are arranged to contain information relating to the modulation method to be carried out by the modulator. At least one of the memory regions provides time independent modulation values and at least one of the memory regions provides time dependent modulation values. Values provided by the memory region is dependent on the data received via the input. Processing means provide a modulating signal based on the values provided by the memory regions.
