Patent ID: 8842649

Claim:
A method for transmitting data between a radio equipment (RE) and a radio equipment control (REC) of a radio base station via Ethernet, said method comprising: in adaptive physical layer, adapting data frames complying with a remote radio protocol to Ethernet data frames that are suitable for transmission over Ethernet physical layer; and transmitting the adapted Ethernet data frames over the Ethernet physical layer, characterized in that, the adapting comprises: filling the data frames complying with the remote radio protocol with redundant bytes, wherein the redundant bytes include control information inside the Ethernet data frame and control information between the Ethernet data frames, the filling comprising: filling a number of /A/ columns, /K/ columns or /R/ columns between the Ethernet data frames so as to output the Ethernet data frames to the Ethernet physical layer via XAUI interface, wherein the /A/ column, /K/ column and /R/ column are respectively Align column, Sync column and Skip column defined by the Ethernet protocol.
