<p>A CPRI interface data transmission method and the device and system thereof, include that: after a transmitter adjusts CPRI data to frames adapting to Ethernet transmission (510), the transmitter transmits the frames via Ethernet line (520); a receiver receives the frames adapting to Ethernet transmission via Ethernet line (530), adjusts the frames adapting to Ethernet transmission to CPRI frames, and obtains CPRI data (540). Before transmitting a CPRI frame of CPRI data, the frame head is transmitted by IQ bandwidth. Between different CPRI frames, the inter frame gap is transmitted by IQ bandwidth. The system applying the method and device of the invention can reduce the transmission cost of CPRI data.</p> |
