内容摘要:


The emerging cellular networks are expected to support massive connectivity with limited radio resources, where interference is one of the dominant performance affecting factors. In this speech, a variety of in cell and beyond cell interference management techniques are presented for cellular networks.

An integrated access and backhaul (IAB) system assisted by an in-band full duplex (FD) relay is presented to extend the cell coverage while maintaining low latency and high reliability, under strong self-interference (SI) due to FD transmission. Following a cost-effective partial SI cancelation at the FD amplify-and-forward relay, the residual SI may be treated as a useful source at base station (BS) to enhance the receiving diversity. The proposed adaptive interference utilization/cancelation scheme achieves a near optimal bit error rate performance and a superior performance in terms of throughput, energy utilization and resource utilization compared to the pervious work. To enhance interference utilization, a virtual multiple-input multiple-output (MIMO) system is modeled by utilizing the residual loopback SI and assisted by power amplifier gain control at FD relay, leading to higher robustness against SI.

Multi-cell interference management via coordinated multipoint (CoMP) transmission is presented for different scenarios. For a cellular vehicle-to-everything (C-V2X) based platoon system, CoMP is used to mitigate the interference at platoon handover between cells, alongside joint optimization of block length and transmission power. The platoon system achieves an optimal effective throughput at a significant complexity reduction over exhaustive search. For a general cellular network, a non-orthogonal multiple access (NOMA) system with coordinated BSs is presented. With multi-criterion user coordination mode selection and low-complexity joint resource allocation, the proposed system enables enhanced energy efficiency and spectral efficiency. The cell-edge users’ performance can be further enhanced by an unmanned aerial vehicle (UAV)-ground BS coordinated NOMA system, where the cell-edge users are jointly served by UAV and ground BS and under more flexible interference management, thanks to the deployment of UAV.
