Abstract

The present application provides a signal transmission system for indoor signal coverage. The signal transmission system includes a baseband processing unit, an antenna unit, a RoC-RRU unit and a LAN cable, and the antenna unit includes a local antenna unit and a distributed antenna unit. The distributed antenna unit includes a radio frequency front-end unit and a first radio access unit, the RoC-RRU unit includes a remote radio unit and a second radio access unit, and the baseband processing unit is connected to the remote radio unit For information exchange, the local antenna unit is connected to the remote radio unit for information exchange, one end of the LAN cable is connected to the remote radio unit through the second radio access unit, and the other end is connected to the remote radio unit through the second A radio access unit is connected with the radio frequency front-end unit for information exchange. The present application also provides a signal transmission method. Through the present application, it is possible to reduce deployment costs and base station costs on the premise of achieving high signal coverage.

Description

technical field [0001] The present application relates to the technical field of signal processing, and in particular to a signal transmission system and a signal transmission method. Background technique [0002] With the emergence of various broadband applications such as smart home and AR / VR, more and more mobile communications are appearing indoors. Communication operators (such as: China Mobile, China Unicom or China Telecom) when building wireless access networks, in addition to considering deploying macro base stations outdoors in the form of cells, they also need to consider indoors (such as office buildings, residences, shopping malls, hospitals, Gymnasiums and schools, etc.) signal coverage issues. [0003] Due to the wide coverage of macro base stations, most macro base stations are currently deployed through optical fibers; however, indoor signal coverage is relatively small, and indoor signal coverage can be carried out through micro base stations. For micro b...
