Difficulties Encountered
The main difficulty encountered is to establish the contents of the time table. Due to some special circumstances, I cannot go to school for normal classes. Therefore, some of the previous courses had some confusion, which caused my actual work content and schedule content to not match each other.
This Week’s Results
This week, I focused on the key technologies of 5G
For 5G, there are six key technologies. The first of these is an ultra-dense heterogeneous network. 5G networks are developing in the direction of network diversification, broadband, integration and intelligence. With the popularity of various smart terminals, mobile data traffic will show explosive growth in 2020 and beyond. In the future 5G network, reducing the cell radius and increasing the number of low-power nodes is one of the core technologies to ensure that the future 5G network will support a 1,000-fold traffic increase. Therefore, ultra-dense heterogeneous networks have become the key technology for future 5G networks to increase data traffic.
The second is Self-organizing network. In traditional mobile communication networks, network deployment and operation and maintenance are mainly relied on manually, which consumes a lot of human resources and increases operating costs, and network optimization is not ideal. In the future, 5G networks will face the challenges of network deployment , operation, and maintenance. This is mainly due to the existence of various wireless access technologies in the network, and the different network node coverage capabilities. The relationship between them is intricate. Therefore, the intelligence of self-organizing network (SON) will become an indispensable key technology for 5G networks.
The third is the Content Distribution Network.In 5G, audio, video, and image services for large-scale users have grown rapidly. The explosive growth of network traffic will greatly affect the service quality of users accessing the Internet. How to effectively distribute high-traffic business content and reduce the delay for users to obtain information has become a major challenge for network operators and content providers. Relying solely on increasing bandwidth does not solve the problem. It is also affected by factors such as routing congestion and delay in transmission, and the processing power of the website server. The occurrence of these problems is closely related to the distance between user servers. Content distribution network (CDN) will play an important role in supporting the capacity of future 5G networks and user access
The fourth is D2D communication.The fourth is D2D communication. In 5G networks, network capacity and spectrum efficiency need to be further improved. Richer communication modes and better end-user experience are also the direction of 5G evolution. Device-to-device communication (D2D) has the prospect of potentially improving system performance, enhancing user experience, reducing base station pressure, and improving spectrum utilization. Therefore, D2D is one of the key technologies in the future 5G network.
The fifth is M2M communication.M2M (machine to machine, M2M), as the most common application form of the Internet of Things, has achieved commercial application in the fields of smart grid, safety monitoring, urban informatization, environmental monitoring
The sixth is information Center Network (ICN).With the increasing proliferation of real-time audio, high-definition video and other services, traditional TCP / IP networks based on location communication cannot meet the requirements of data traffic distribution. The network presents an information-centric development trend. As a new network architecture, the goal of ICN is to replace the existing IP
