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 "instantaneous relaying for the 3 way relay channel with circular message exchanges"):
  Abstract: The 3-user discrete memoryless multi-way relay channel with circular message exchange and instantaneous relaying is investigated. We first show that this channel is effectively a 3-user interference channel with receiver message side information for every fixed (and instantaneous) relay mapping. Then, we extend the Han-Kobayashi coding scheme to this channel. Finally, we apply these results to Gaussian channels with amplify-and- forward relaying and present numerical results showing the gain of the proposed scheme compared to the state of the art.

  Member "resource allocation for energy efficient 3 way relay channels":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "game theory for multi access edge computing survey use cases and future trends")
  Member "on the capacity of the k user cyclic gaussian interference channel":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "on the optimality of treating inter cell interference as noise in uplink cellular networks")
  Member "gaussian interference channel capacity to within one bit":

      - Hyperedge HE-3 (induced by source paper "fundamental limits of wireless caching under mixed cacheable and uncacheable traffic")
