At present, 80% of the traffic of mobile communication is generated indoors. Therefore, how to develop a new generation indoor distribution system to improve the indoor wireless coverage quality of the 5G mobile communication network has become a key common problem to be solved urgently in 5G network scale networking.
Most indoor common scenes at present have deployed huge passive indoor subsystems during 3G and 4G network infrastructure, and mainly aiming at the application scheme, some radio frequency conversion systems have been proposed in the industry at present, 5G single-channel or double-channel signals are moved to an idle frequency band suitable for transmission of the current indoor distribution system through frequency conversion, then the frequencies are restored in an antenna covering unit, and the signals are transmitted and covered through a new antenna, so that the 5G double-channel signals are transmitted in the current single-channel indoor passive distribution network. However, the current frequency conversion system consists of a conventional 5G RRU, an access unit, and a covering unit, as shown in fig. 1.

In the coverage unit, the functions of frequency conversion reduction, TDD synchronization and amplification are required. For the distributed system, generally, one access unit supports more than 20 covering units, the cost of the covering units determines the manufacturing cost of the whole system, in the covering units, besides the necessary functions of conventional mixing, amplification and the like, the most main factors influencing the cost have two aspects, namely, firstly, the realization of the synchronous function of the covering units is realized, generally, an independent synchronous module is adopted, or a synchronous reference signal is transmitted through the access unit, then, the secondary processing is carried out after the covering units receive the synchronous reference signal, and then, the uplink and downlink switching of an amplifying circuit is controlled. Secondly, frequency conversion frequency source reduction is carried out, in order to enable a system to meet the frequency error requirement of 5G communication, a frequency reference source of a covering unit needs to be consistent with an access unit, the access unit is generally adopted to transmit independent frequency reference signals in the aspect of realization, the reference source reduction is carried out on the covering unit, and then the frequency reference signals are used for an internal phase-locked loop to generate frequency signals required by a mixer. The difficulty and cost of implementing both aspects is relatively large compared to the cost of the cover unit. Therefore, it is necessary to develop a low-cost 5G signal rf conversion distribution system.
