Wireless fronthaul system for simulating optical transmission facing 5G power reuse

Abstract

The present invention provides a wireless fronthaul system for simulating optical transmission facing 5G power reuse. The system comprises a BBU pool, feed line fibers, a far-end mode, distributed fibers, a user terminal UE and a RRU unit. The BBU pool is connected with the far-end node through an optical line terminal via the feed line fibers, the output end of the far-end node is connected with the input end of the distributed fibers, the output end of the distributed fibers is connected with the RRU unit, and the output end of the RRU unit is sent to the user terminal UE through the antenna via an air interface. The wireless fronthaul system for simulating optical transmission facing 5G power reuse realizes the reuse of the simulation signals based on the subcarrier modulation at the signal power dimension so as to improve the spectral efficiency in the future mobile communication system and increase the transmission capacity. Besides, the wireless fronthaul system for simulating optical transmission facing 5G power reuse can distinguish different user data through the size of the superposed signal power and select the size of the power according to the distance from a user to the base station processing unit to realize the power reuse so as to solve the problem that the system performance is not balanced caused by the far and near effect of the wireless terminal access user.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a wireless fronthaul system for analog optical transmission for 5G power multiplexing. Background technique [0002] With the rapid development of communication technology and the continuous evolution of technical standards, the emergence of the fourth generation mobile communication technology (4G) has enabled its data service transmission rate to reach 100 megabits or even gigabits per second, which can meet certain requirements to a certain extent. demand for broadband mobile communication applications. However, with the continuous growth of the popularization and application of intelligent terminals and the demand for new mobile services, the demand for wireless transmission rate increases exponentially, and the transmission rate of wireless communication will still be difficult to meet the application requirements of future mobile communication. ...
