The present invention provides a combining device for combining radio signals during uplink transmission in an indoor communication system. The system comprises an Ethernet switch connected to a base station and to at least a first and second radio remote headend (RRH). The RRH is adapted for expanding the wireless coverage of the base station. The combining device comprises: means for receiving at least a packet flow from the Ethernet switch, wherein the packet flow comprises packets from at least the first and second RRH, the packet comprises packet data, RRH identification and time stamp of the packets; means for separating the packets according to the RRH origin into at least first and second RRH packet, using the RRH identification; and means for matching the packets with identical time stamp between the first and the second RRH packets. The combining device also comprises means for summing the packet data of the matched packets and means for transmitting the summation of the packet data to the Ethernet switch.
