Query: CGN: A Capacity-Guaranteed Network Architecture for Future Ultra-Dense
  Wireless Systems   The sixth generation (6G) era is envisioned to be a fully intelligent and
autonomous era, with physical and digital lifestyles merged together. Future
wireless network architectures should provide a solid support for such new
lifestyles. A key problem thus arises that what kind of network architectures
are suitable for 6G. In this paper, we propose a capacity-guaranteed network
(CGN) architecture, which provides high capacity for wireless devices densely
distributed everywhere, and ensures a superior scalability with low signaling
overhead and computation complexity simultaneously. Our theorem proves that the
essence of a CGN architecture is to decompose the whole network into
non-overlapping clusters with equal cluster sum capacity. Simulation results
reveal that in terms of the minimum cluster sum capacity, the proposed CGN can
achieve at least 30% performance gain compared with existing base station
clustering (BS-clustering) architectures. In addition, our theorem is
sufficiently general and can be applied for networks with different
distributions of BSs and users.
