Abstract

The embodiment of the invention discloses a cellular communication system, a data transmission method and equipment thereof and a communication system. The cellular communication system comprises power line interface small cell equipment, wherein the power line interface small cell equipment is connected with core network equipment through a power line, and used for performing power line signal processing, wireless cellular network baseband processing, digital-to-analog conversion and frequency conversion on a downlink signal of a power line carrier frequency returned by the core network equipment through the power line to obtain a downlink analog data signal of a cellular coverage frequency point to be transmitted through an antenna, and / or used for performing frequency conversion, analog-to-digital conversion, wireless cellular network baseband processing and power line signal processing on an uplink analog data signal of a cellular coverage frequency point received by the antenna, and returning the uplink analog data signal to the core network equipment through the power line. A digital returned signal of a cellular communication system is transmitted through power line infrastructure, so that the deployment difficulty of an indoor cellular communication system is lowered, and the deployment cost of the indoor cellular communication system is reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a cellular communication system and its data transmission method, equipment and communication system. Background technique [0002] With the rapid development of wireless communication technology, multimedia services such as image, video, and Internet browsing have become the main service requirements of current mobile users, which makes the user's data traffic demand increase day by day. Therefore, how to provide users with faster and more connections has become the main goal of the evolution of mobile communication systems in the future 5G era. [0003] In the current 5G research, ultra-dense networking will effectively solve the problems of high number of connections and large capacity requirements in the future, and is an important potential networking form. However, in ultra-dense networking, the number of micro base stations is large, and the requirements for the backhau...
