Abstract: A 6G-oriented heterogeneous large-scale distributed network (Het-LDN) is proposed. It consists of a large number of heterogeneous distributed wireless nodes with low-cost, low-power, high-performance, easy-to-deploy, and easy-to-scalable features, which meets the various requirements of future wireless communications, including realizing extreme cellular system capacity, guaranteeing ultra-high feasibility transmission, supporting massive users' simultaneous access, and acquiring consistent user experience. Hierarchical distributed network structure and multi-link cooperative transmission scheme are presented. Simulation experiments demonstrate its performance advantages in terms of user throughput. It is believed that this network can be a highly competitive commercial solution for 6G.
