摘要:

研究了下行非正交多址接入(NOMA)网络中覆盖概率的Meta分布。基于NOMA用户的位置评估两种方案:1)网络中的任何地方,2)仅小区中心用户。这两个计划的MD的时刻推导和MD近似通过β分布。对于第一种方案,导出了闭合形式的力矩;对于第二种方案,导出了精确和近似的力矩,以简化积分计算。我们表明,限制NOMA小区中心用户提供了显着更高的平均值,更低的方差和更好的百分位性能的CP。

英文摘要:

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.
