Efficient Power Allocation for Multi-Cell Uplink NOMA Network
2019
2019 IEEE 89th Vehicular Technology Conference (VTC2019-Spring)
Preserved Fulltext
Specifically, we propose a power optimization technique for NOMA to improve the sum-rate in a multi-cell environment. ...
The simulation results show that the proposed NOMA approach outperforms conventional orthogonal multiple access (OMA) technique in the multi-cell uplink scenario. ...
To fill this glaring gap in NOMA literature, we aim to develop a comprehensive case study of uplink NOMA system that optimizes the power allocation to manage interference in a multi-cell environment. ...
