Hybrid networking method of pRRU between eCPRI protocol and CPRI protocol in 5G system

Abstract

The invention discloses a hybrid networking method for pRRUs between an eCPRI protocol and a CPRI protocol in a 5G system, in a hardware system, the pRRUs simultaneously have two sets of clock systemsrequired by two data communication interface protocols of eCPRI and CPRI, two groups of SFP photoelectric conversion modules on the pRRUs are respectively SFP0 and SPF1, and two mutually independentlogic high-speed serial bus interfaces Serdes of an FPGA; wherein the two protocols are respectively responsible for processing an eCPRI protocol and a CPRI protocol. According to the invention, the interface type of the RRU can be flexibly changed, and the RRU can be conveniently connected with a 5G base station, a pRRU and a CPRI HUB (extension connection equipment of a CPRI interface protocol and equipment capable of extending one CPRI interface into a plurality of CPRI interfaces) equipment. Thus, the 5G sector density is reduced, frequent switching of UE equipment is reduced, the networkoptimization difficulty is reduced, and the network comprehensive construction cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a mixed networking method of pRRU between eCPRI protocol and CPRI protocol in 5G system. Background technique [0002] At present, pRRU (miniature remote radio unit) is a product structure form in the 5G communication system, and has been widely used in the coverage of the 5G communication system. However, due to the high frequency band of 5G signals, the attenuation of wireless signals in space is relatively large, so the construction density of 5G base stations will be very high. However, due to the complex terrain in the city and the more complex indoor environment, the sector switching of 5G will be more frequent and complicated. The wireless network optimization (referred to as network optimization refers to the various aspects of wireless network optimization after the completion of the communication network. A kind of optimization (including hardware, sof...

AI Technical Summary

Problems solved by technology

In some areas with complex terrain, signal overlap areas are likely to occur between sectors, and mutual interference occurs

At the same time, there will be signal gaps in some areas, that is, areas that cannot be covered by nearby RRUs.

The area of ​​these blank areas is not large, so it is not suitable to add another RRU for coverage, because it is easy to cause serious inter-sector interference problems, and the sector density is too high, it is also easy to cause frequent sector switching problems, affecting communication efficiency , and finally the construction cost of doing so is too high
