Jointly Coordinated GUE-to-BS Multipoint Terminals in Dense Multi-UAV C-NOMA Network Environment

초록

This paper presents a jointly coordinated multipoint (JT-CoMP) wireless terminals with unmanned aerial vehicle (UAV) based cooperative non-orthogonal multiple access (C-NOMA) cellular network. A total of ten (10) terminals were structured. Stochastic analysis of the scheme's impact with anticipated estimations of its inherent network variation challenges within the confined spectrum-sharing zone is conducted and mitigated. We then introduced four (4) novel GUEs-BSs terminal communication protocols to orchestrate communication among the deployed component terminals. The four communication protocols are the single-hop (direct), the multihop, the selective-decode-and-forward (SDP), and the incremental-decode-and-forward (IDF) protocol models. The proposed multi-UAV uplink-downlink (UL-DL) model is later deployed into direct-dense and relay-dense network environments to ascertain its robustness. As depicted, the model's performance evaluation validates antenna gain, low transmission power and improved normalized throughput in both line-of-sight (LoS) and non-line-of-sight (NLoS) conditions.
