Overview
Multiple-input, multiple-output (MIMO) channels have not only the degrees of freedom of time and frequency involved in classical Shannon's information theory, but also the degrees of freedom in space. MIMO has become the most effective core means of 4G and 5G to improve system capacity and spectral efficiency[1].。It can be expected that in the future, on the basis of 5G, the air-space-ground-sea ubiquitous communication network will be adopted, and new spectrum, ultra-large-scale antennas, and large-scale distributed collaborative MIMO will be usedTechnologies such as communication and sensing integration will develop wireless transmission systems with wider coverage, higher transmission rates, higher reliability, and lower latency, so as to build a new generation of universal, intelligent, and full-service mobile information infrastructure.
Green communication networks are not only the common vision of the industry to reduce network costs, but also the only way for the world to achieve the "dual carbon" goal。With the introduction of more new frequencies, new technologies, and new field recordings, the energy consumption of hyperscale MIMO will become increasingly prominent. At the same time, due to the constraints of devices and interference, the spatial diversity gain brought by larger-scale MIMO will also tend to be saturated, and intelligent MIMO combined with artificial intelligence (AI) technology may bring new vitality to communication networks.
This report focuses on green and intelligent hyper-scale MIIMO, and expounds the current hot technologies and research status of hyper-scale MIMO technology from the two dimensions of energy saving and intelligence.
Chapter 3 focuses on the green energy-saving network architecture, on the one hand, from the perspective of improving the existing network architecture to achieve network energy saving, on the other hand, Cell-free, RIS and other technologies, and describes the potential energy-saving solutions in 6G networks.
The fourth chapter focuses on wireless air technology, combined with the current network status and standard progress, and analyzes the potential air interface energy-saving methods in current and future communication networks.
Chapter 5 focuses on the application of AI technology in ultra-large-scale MIMO, and firstly introduces the intelligent channel state information feedback method and beam management scheme from the perspective of space-based technology. Then, combined with the characteristics of communication network, the potential direction of network energy-saving management is analyzed.
Based on the content of this technical report, green and intelligent hyperscale MIMO will bring huge benefits to the future 6G mobile communication network, but there are still many challenges, such as the forward compatibility of network architecture, the balance between network energy consumption and performance, and the low complexity and reliability of AI technology.
