Abstract

The invention provides a signal transmission system, which is used for indoor signal coverage. The signal transmission system comprises a baseband processing unit, an antenna unit, a RoC-RRU unit andan LAN cable, wherein the antenna unit comprises a local antenna unit and a distributed antenna unit; the distributed antenna unit comprises a radio frequency front-end unit and a first radio access unit; the RoC-RRU unit comprises a remote radio unit and a second radio access unit; the baseband processing unit is connected with the remote radio unit for information interaction; the local antennaunit is connected with the radio remote unit for information interaction; one end of the LAN cable is connected with the radio remote unit through the second radio access unit, and the other end of the LAN cable is connected with the radio front-end unit through the first radio access unit for information interaction. The invention further provides a signal transmission method. According to the signal transmission system, on the premise of realizing high signal coverage, the layout cost and the base station cost can be reduced.

Description

Technical field [0001] This application relates to the field of signal processing technology, and in particular to signal transmission systems and signal transmission methods. Background technique [0002] With the emergence of various broadband applications such as smart home and AR / VR, more and more mobile communications appear indoors. When building wireless access networks, communication operators (such as China Mobile, China Unicom, or China Telecom) need to consider not only deploying macro base stations in a cellular manner outdoors, but also indoors (for example, office buildings, residences, shopping malls, hospitals, etc.). Gymnasiums, schools, etc.) signal coverage issues. [0003] Due to the wide coverage of macro base stations, most of the current macro base stations are deployed through optical fibers; while indoor signal coverage is relatively small, and indoor signal coverage can be carried out through micro base stations. For micro base stations, if signal covera...
