METHOD FOR DATA COMMUNICATION BETWEEN RADIO CONTROL EQUIPMENT AND RADIO EQUIPMENT, RADIO CONTROL EQUIPMENT AND RADIO EQUIPMENT

摘要

In a conventional base transceiver station, a radio equipment control (REC) and radio equipment (RE) are provided for each mobile communication system, and radio signal data (IQ data) is independently received and transmitted. Therefore, in order to handle a plurality of mobile communication systems, large facility and costs are required. The RE is shared so as to use a plurality of types of a radio signal, and data (IQ data) of a plurality of types of the radio signal and monitoring control data are variably arranged in a transfer frame for transmitting and receiving data between the RE and the RECs. A plurality of types of data are simultaneously transmitted and received by one communication link between the RECs and the RE.
