How does the standardization process for 6G differ from previous generations?

The development of 6G was still in its early stages, and there weren't established finalized standards for 6G yet. However, based on the general trends and the evolution from previous generations (like 5G), here are some technical aspects that might be considered or could potentially differ in the standardization process for 6G:

1. Higher Frequencies and Spectral Efficiency: 6G is anticipated to operate at significantly higher frequencies (terahertz band), which would allow for much faster data rates compared to 5G. Standardizing these higher frequencies and ensuring reliable communication at such ranges would be a key focus. Spectral efficiency improvements are also crucial to make better use of the available frequency bands.
2. Novel Antenna Technologies: Given the higher frequencies, new antenna technologies may be required to enable efficient transmission and reception of signals. These might include metamaterials, beamforming, massive MIMO (Multiple Input Multiple Output), or even technologies beyond MIMO to enhance coverage, capacity, and reliability.
3. Integration of AI and Machine Learning: 6G is expected to heavily involve AI and machine learning to optimize network performance, manage resources, predict user behavior, and adapt to dynamic environments. Standardization efforts might involve defining protocols and interfaces to integrate AI algorithms within the network infrastructure.
4. Green and Sustainable Networks: Energy efficiency and sustainability might play a more prominent role in 6G standardization. Efforts could focus on designing energy-efficient hardware, reducing network carbon footprint, and optimizing power consumption in devices and network components.
5. Ultra-Reliable Low-Latency Communication (URLLC): While 5G made strides in reducing latency, 6G might aim for even lower latency and higher reliability, enabling applications like real-time remote surgery, autonomous vehicles, and highly responsive tactile internet. Standardization might involve defining stringent requirements and protocols to achieve URLLC.
6. Security and Privacy Enhancements: With the proliferation of connected devices and data exchange, enhanced security and privacy measures would be a significant concern in 6G. Standardization might emphasize robust encryption, authentication protocols, and privacy-preserving techniques to safeguard user data and communications.
7. Global Collaboration and Interoperability: Given the global nature of communication standards, the standardization process for 6G would likely involve collaboration among international organizations, governments, industry players, and academia to ensure interoperability and global deployment.
8. Regulatory Challenges and Spectrum Allocation: As with previous generations, regulatory challenges concerning spectrum allocation and licensing will be significant in the standardization process. Determining suitable frequency bands, licensing procedures, and global coordination would be crucial.
9. New Use Cases and Applications: 6G may introduce entirely new use cases and applications that were not previously feasible. Standardization efforts would need to anticipate and cater to these emerging applications, ensuring the network's capability to support them effectively.
