摘要：A distributed radio base station (20) comprises a radio equipment controller(REC) (22) situated at a main site (23) and a radio equipment (RE) (24) situated at a remotesite (25). A remote unit (102, 104, 106, 108, 110, 124) configured to engage in directcommunications with the radio equipment controller (REC) is also situated at the remotesite (25). An internal interface (26) connects the radio equipment controller (REC) and theradio equipment (RE). Advantageously, the internal interface (26) also encapsulates thedirect communications between the radio equipment controller (REC) (22) and theremote unit, thereby obviating a separate physical link between the radio equipmentcontroller (REC) and the remote unit. A new physical link (130) transmits, between theradio equipment (RE) and the remote unit, the direct communications between the radioequipment controller (REC) and the remote unit which are encapsulated over the internalinterface (26). The remote unit can take various differing forms, including that of anantenna (102) with remote electrical tilt control; a tower mounted amplifier (TMA) (104);a Transmission network unit (106); a separate radio base station (108) which is co-located

at the remote site; a proprietary equipment unit (110); or even one or more cascadedradio equipments (RE) (124).
