PROBLEM TO BE SOLVED: To solve the problem in which, although an 8b10b coding scheme is used for the existing CPRI, the scheme has many overhead parts and a band usage amount is oppressed.SOLUTION: A CPRI transmission scheme makes it possible to perform transmission with mere 8bit(8b) between a control base band part (Base Band Unit;BBU) and a radio part (Remote Radio Head;RRH) of a radio base station, formerly transmitted in an existing CPRI with a frame length of 10bit (10b), to reduce a band usage amount. |
