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 "the degrees of freedom region of the mimo cognitive interference channel with no csit"):
  Abstract: The cognitive interference channel (C-IC) is defined as the interference channel (i.e., it consists of two transmitter-receiver pairs) in which any subset of the four terminals is cognitive. The degrees of freedom (dof) region of the C-IC is studied for the case in which there is perfect and no channel state information at the receivers and the transmitters, respectively. The inner and outer-bounds to the dof region are proposed. These bounds yield the perfect characterization of dof region, except for a few cases of cognition for which, over a small subset of all possible values of the number of antennas at four terminals, the bounds are not tight. Lastly, an example on the feasibility of the interference alignment, without the knowledge of the actual channel realizations at the transmitters, is presented.
