  In this paper, joint transmission coordinated multipoint (JT-CoMP) is
exploited by using virtual user pairing non-orthogonal multiple access
(VP-NOMA), termed as JT-CoMP VP-NOMA. The technique combines both VP-NOMA for
enhancing ergodic sum capacity (ESC) and JT-CoMP for inter-cell interference
mitigation. To show the performance gains, ESC of a three-cell scenario is
analyzed as a key performance metric. The analytical and simulation results of
JT-CoMP VP-NOMA are compared with orthogonal multiple access (OMA),
non-orthogonal multiple access (NOMA), and VP-NOMA. It is shown that the
proposed JT-CoMP VP-NOMA outperforms the other schemes in the viewpoint of ESC.
