This report explores the bottlenecks in
the evolution of 5G/6G systems from planar cellular coverage to full-dimensional coverage (characterized by ultra-long-range, ultra-dense, and ultra-high-altitude coverage). It proposes key technologies for full-dimensional coverage systems, including:
– Dense interference management principles
– Networked interference management techniques
– Novel resource-cell coverage architectures
– Ultra-dense coverage methods
– Three-dimensional, seamless, and hole-free continuous coverage methods
– Remote self-organizing, companion-style coverage methods
These technologies can boost the transmission rate per unit area by an order of magnitude.
Furthermore, the report outlines pathways to break through the limitations of traditional wireless cellular coverage: transitioning from signal coverage to capacity coverage, from planar to three-dimensional coverage, from fixed to wide-area on-demand coverage, and ultimately to green, low-carbon coverage. These insights provide valuable references for accelerating the broader application of 5G—such as in the low-altitude economy, vertical industries/key zones, strategic oil and gas exploration, and emergency disaster relief—and for shaping the architecture of future 6G systems.
