Executive Summary
The development of information technology is a process of continuous emergence and integration
of new technologies. The 5G era has completed the integration of information and communication
technology (ICT). In the trend of evolution to 6G, ICT is further integrated with big Data, artificial
intelligence technology, presenting the characteristics of ICDT (Information, Communication，big
Data Technology) integration.
ICDT integrated 6G is an end-to-end information processing and service system. It is a mobile
information network with strong connectivity, strong computing power, strong intelligence, and
strong security. A large number of new technologies and new functions have become candidates
for 6G design, and the performance of the scheme has been verified at different levels such as
theory, simulation and prototype.
This white paper attempts to classify and integrate 6G potential technologies and solutions from a
system perspective, and gives technical system suggestions. According to functional characteristics,
6G technology can be roughly divided into four directions: wireless communication, wireless
network, functional architecture and system operation. Among them, wireless communication
aims to improve the point-to-point transmission performance, wireless network aims to achieve
the capabilities of multi-band networking, enhanced coverage, network sensing, lean network and
the full life-cycle information process through platform-based, structured, service-oriented and
biochemical design. The goal of system networking is to achieve self-growth, self-optimization and
self-evolution of network operation capabilities, and improve energy and resource efficiency.
In terms of wireless communication and networking, the integrated sensing and communication,
reconfigurable intelligent surface and intelligent interference coordination have attracted much
attention, and are also the key directions of 5G enhancement. At present, these technologies have
completed the design of technical solutions and prototype solutions, and are undergoing field
testing. In terms of network architecture and functions, lean network, intelligent native network,
service-based wireless network, mobile computing network, digital twin network, intelligent
