Optimal Resource Allocation for Power-Efficient MC-NOMA with Imperfect Channel State Information
Zhiqiang Wei, Derrick Wing Kwan Ng, Jinhong Yuan +1
In this paper, we study power-efficient resource allocation for multicarrier non-orthogonal multiple access (MC-NOMA) systems. The resource allocation algorithm design is formulate…
Fairness Comparison of Uplink NOMA and OMA
Zhiqiang Wei, Jiajia Guo, Derrick Wing Kwan Ng +1
In this paper, we compare the resource allocation fairness of uplink communications between non-orthogonal multiple access (NOMA) schemes and orthogonal multiple access (OMA) schem…
Performance Analysis of a Hybrid Downlink-Uplink Cooperative NOMA Scheme
Zhiqiang Wei, Linglong Dai, Derrick Wing Kwan Ng +1
This paper proposes a novel hybrid downlinkuplink cooperative NOMA (HDU-CNOMA) scheme to achieve a better tradeoff between spectral efficiency and signal reception reliability than…
