DEVICES AND METHODS FOR 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.

1) A multiplexer/demultiplexer device configured to multiplex and demultiplex common public radio interface (CPRI) data streams exchanged between a radio equipment controller (REC) and a plurality of radio equipment (REs), the device comprising:
a REC interface configured to receive a first downlink CPRI data stream from the REC and to transmit a first uplink CPRI data stream to the REC; a plurality of RE interfaces configured to each transmit a respective one of a plurality of second downlink CPRI data streams to a respective one of the plurality of REs and to each receive a respective one of a plurality of second uplink CPRI data streams from a respective one of the plurality of REs; circuitry operatively connected to the REC interface and to the RE interfaces, the circuitry being configured to:
demultiplex the first downlink CPRI data stream received from the REC;generate the plurality of second downlink CPRI data streams from the demultiplexed first downlink CPRI data stream;multiplex the plurality of second uplink CPRI data streams received from the plurality of REs;generate the first uplink CPRI data stream from the multiplexed plurality of second uplink CPRI data streams.
