METHOD, APPARATUS AND SYSTEM FOR BASEBAND RF INTERFACE BEARER TRANSMISSION

摘要

Disclosed is a method for baseband RF interface bearer transmission, comprising: transforming a service signal of a client device to a first baseband signal, wherein the client device is an external device of a remote system which an RF Remote Unit (RRU) and a Building Baseband Unit (BBU) belong to; multiplexing the first baseband signal and the original baseband signal between the RRU and the BBU to a second baseband signal, wherein the transmission rate of the second baseband signal is faster than the transmission rate of the original baseband signal; bearing the second baseband signal on the baseband RF interface, and transmitting the second baseband signal on the line between the RRU and the BBU. Also disclosed are a control apparatus for baseband data processing, base station transceiver apparatus and system. Through the embodiment of the invention, the service signal of the external client device of the remote system is mapped into the baseband signal and transmitted. Thereby the cost is low and the supervision is also easy to perform.
