Conclusion
MIMO communication is an indispensable key technology for the 6G wireless network. Under the requirement of extremely low-latency communication in 6G, the MIMO capacity exhibits the channel capacity collapse effect. The spatiotemporal exchangeability theory of MIMO channel and the spatiotemporal 2-D channel coding are promising approaches to combat this effect and to enable extreme connectivity for 6G. Fundamental researches in this area are still in its beginnings. Comprehensive simulation validations and constructing experimental systems in practical scenarios are necessary to further validate relevant theories and technologies. They are helpful to promote research in this area towards maturity.
