Résumé:
This letter focuses on clustering and Resource Block
(RB) allocation in multi-carrier uplink networks using Power-
Domain Non Orthogonal Multiple Access (PD-NOMA). The
optimization objective is time-based Proportional Fairness. PD-NOMA
is applied per frame and RB only if the achieved
individual data rates are larger with PD-NOMA than with
Time Division Multiple Access. The clustering algorithm recursively
uses maximum weight matching to build clusters per
RB. Given the clusters, RB allocation is then optimal. The
proposed algorithm provides a good trade-off between reduced
overall network latency and rate improvement compared to two
reference algorithms.
