摘要： System having baseband units; a radio equipment controller module; radio equipment modules coupled to a physical antenna port having a slave port coupled to a master port of the radio equipment controller module or another radio equipment module. The radio equipment modules receive an uplink antenna-carrier stream from a physical antenna port and transmit the stream to its slave port and, if a master port is connected to another radio equipment module, it synchronizes and sums the stream with an uplink antenna-carrier stream from said master port, creating a summed uplink antenna-carrier stream transmitted to its slave port. The radio equipment modules receive a downlink antenna-carrier stream from the radio equipment controller module or another radio equipment module to its slave port for transmission to said physical antenna port and, if a master port is connected to another radio equipment module, forwards the downlink antenna-carrier stream to the master port.
