  In this paper, we consider a hybrid scheme of coordinated multi-point (CoMP)
technology in MISO heterogeneous communication networks based on power domain
non-orthogonal multiple access (PD-NOMA). We propose a novel method based on
matching game with externalities to realize the hybrid scheme where the number
of the cooperative nodes are variable. Moreover, we propose a new matching
utility function to manage the interference caused by CoMP and NOMA techniques.
  We also devise robust beamforming to cope with the channel uncertainty. In
this regard, we focus on both no CSI and partial CSI cases to increase the
achievable data rate.
  We provide the complexity analysis of both schemes which shows that the
complexity of the partial CSI approach is more than that of the no CSI method.
  Results evaluate the performance of proposed CoMP scheme and the sensibility
of our methods, Index Terms, CoMP technology, hybrid scheme, matching game with
