human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "leo small satellite constellations for 5g and beyond 5g communications"):
  Abstract: The next frontier for 5G and post-5G networks towards truly ubiquitous connectivity is the use of Low Earth Orbit (LEO) small-satellite constellations to support the three 5G use cases: enhanced mobile broadband (eMBB), massive machine-type communications (mMTC), and ultra-reliable low-latency communications (URLLC). This paper provides a comprehensive overview of the architectural and technology components that enable the full integration of these networks into 5G and post-5G systems.

Includes members:
  Member "architectures and key technical challenges for 5g systems incorporating satellites":
    also connected through other hyperedges:
