This application relates to a remote radio unit and a networking system between RRU and BBU. The remote radio unit includes an FPGA unit, a digital intermediate frequency unit, a radio frequency unit and a first network interface unit, and the FPGA unit, the digital intermediate frequency unit and the radio frequency unit are connected in sequence The first network interface unit is connected with the FPGA unit through the RMII interface, and the FPGA unit establishes the first communication connection with the baseband processing unit through the CPRI interface; the FPGA unit is used to receive the RMII interface protocol data from the first network interface unit, and connects through the first communication Transmitting the RMII interface protocol data to the CPU unit of the baseband processing unit, and receiving the first response data in response to the RMII interface protocol data from the CPU unit of the baseband processing unit. The application solves the problems of high cost and long software development cycle of the radio remote unit, and achieves the beneficial effects of reducing the cost of the radio remote unit and shortening its software development cycle.
Description
technical field [0001] The present application relates to the technical field of communication, in particular to a remote radio unit and a networking system of RRU and BBU. Background technique [0002] In the existing wireless communication system, the base station (eNB) of the access network is usually composed of an indoor baseband processing unit (Building Baseband Unit, BBU) and a radio remote unit (Radio Remote Unit, RRU). The remote units are connected through optical fibers or cables, and use protocols such as a common public radio interface (Common Public Radio Interface, CPRI) or an open wireless interface (Open Radio Interface, ORI) for data exchange. [0003] The base stations in the existing wireless communication systems are mostly composed of a baseband processing unit BBU and multiple radio remote units RRU. By placing the base stations in an available central computer room, the baseband part can be processed centrally; at the same time, Optical fibers are u...
