Query: Bounds on the Capacity of the Multiple Access Diamond Channel with
  Cooperating Base-Stations   A diamond network is considered in which the central processor is connected,
via backhaul noiseless links, to multiple conferencing base stations, which
communicate with a single user over a multiple access channel. We propose
coding techniques along with lower and upper bounds on the capacity. Our
achievability scheme uses a common cloud coding strategy based on the technique
proposed by Wand, Wigger, and Zaidi (2018) and extends it beyond two relays.
Our upper bounds generalize the method proposed by Bidokhti and Kramer for the
two relay diamond network without cooperation (2016) and lead to new bounds for
the multiple relay setting. Specializing our upper bounds for the two relay
scenario (with cooperation), we provide new bounds and improve
state-of-the-art.
