Description
Technical Field
The invention relates to the technical field of fifth-generation mobile communication, in particular to a 5G terminal anti-interference degree testing method, a 5G terminal anti-interference degree testing system and 5G terminal anti-interference degree testing equipment.
Background
The 5G (5 th-Generation, fifth Generation mobile communication technology), which is called fifth Generation mobile communication technology, is also called fifth Generation mobile communication technology, and is an extension after 4G (4 th-Generation, fourth Generation mobile communication technology) is under study. There is currently no public specification or official document of any telecommunications company or standardization body mentioning 5G.
Future 5G technology is evolving towards network diversification, broadband, integration and intellectualization. With the popularity of various intelligent terminals, mobile data traffic will show explosive growth in 2020 and later. In the future 5G network, the cell radius is reduced, the number of low-power nodes is increased, and the method is one of core technologies for ensuring that the future 5G network supports 1000 times of flow increase. Therefore, ultra-dense heterogeneous networks are a key technology for improving data traffic for future 5G networks.
Future wireless networks will deploy various wireless nodes more than 10 times beyond existing sites, within the macro coverage area, inter-site distances will remain within 10 meters, and support servicing 25000 users per kilometer. Meanwhile, the proportion of the number of active users to the number of stations can be 1:1, namely the one-to-one correspondence between users and service nodes. The densely deployed network shortens the distance between the terminal and the node, so that the power and the spectrum efficiency of the network are greatly improved, the network coverage area is enlarged, the system capacity is expanded, and the flexibility of the service among different access technologies and different coverage layers is enhanced. Although ultra-dense heterogeneous network architecture has great development prospect in 5G, the reduction of the distance between nodes, more dense network deployment will make the network topology more complex, so that the problem of incompatibility with the existing mobile communication system easily occurs. In 5G mobile communication networks, interference is a problem that must be addressed. The interference in the network is mainly: common frequency interference, shared spectrum resource interference, interference among different coverage layers, and the like. In 5G networks, the transmission losses of neighboring nodes are typically not very different, which results in multiple interference sources of similar strength, further degrading network performance.
However, the inventors found that there are at least the following problems in the prior art:
in the research of the fifth generation mobile communication technology, no public specification or official document of any telecom company or standard establishment refers to 5G, and the capability of testing the interference resistance of a 5G terminal cannot be realized at present.
