  We study the meta distribution (MD) of the coverage probability (CP) in
downlink non-orthogonal-multiple-access (NOMA) networks. Two schemes are
assessed based on the location of the NOMA users: 1) anywhere in the network,
2) cell-center users only. The moments of the MD for both schemes are derived
and the MD is approximated via the beta distribution. Closed-form moments are
derived for the first scheme; for the second scheme exact and approximate
moments, to simplify the integral calculation, are derived. We show that
restricting NOMA to cell-center users provides significantly higher mean, lower
variance and better percentile performance for the CP.
