MULTIPLEXING AND DEMULTIPLEXING COMMON PUBLIC RADIO INTERFACE DATA STREAMS

摘要

Devices and methods are provided to allow the multiplexing and demultiplexing of Common Public Radio Interface (CPRI) data streams exchanged between a Radio Equipment Control (REC) and a plurality of Radio Equipment (RE) in a radio base station system. The device is generally configured to demultiplex a first downlink CPRI data stream received from the REC, generate a plurality of second downlink CPRI data streams from the demultiplexed first downlink CPRI data stream, multiplex a plurality of second uplink CPRI data streams received from the plurality of REs, and generate a first uplink CPRI data stream from the multiplexed plurality of second uplink CPRI data streams.
