摘要

提高频谱效率是下一代第五代移动通信(5G)系统的一个重要问题。基于 5G 信号格式的全双工蜂窝(FDC)和动态全双工(DDC)系统(5G-FDC 和 5G-DDC)因将带内全双工(IBFD)引入 5G 而备受关注。然而,基站(BS)的自干扰(SI)和用户设备(UE)的用户间干扰(IUI)是实现 FDC 和 DDC 系统的重大障碍。本研究针对 5G 的信号配置和信道编码,提出了一种基于连续干扰消除的 IUI 消除(IUIC)方案。此外,我们还为 5G-DDC 引入了用户调度和自适应调制算法。我们利用链路和系统级仿真对所提出的方案进行了评估。结果表明,在接收质量下降 3.4 dB 的情况下,IUI 明显降低了 40 dB。此外,与传统 5G-DDC 相比,我们的 IUIC 方法降低了近距离 UE 对的 IUI,扩大了 IBFD 操作的候选 UE 对,并将下行链路时隙中的 IBFD 应用率显著提高了 51.0%。此外,当 BS 和 UE 发射功率达到最大值时,上行链路平均吞吐量增益增加了 11.4%。

Inter-User Interference Cancellation Scheme for 5G-Based Dynamic Full-Duplex Cellular System
Improving spectral efficiency is an important issue for the next generation of the 5th generation mobile communication (5G) systems. Full-duplex cellular (FDC) and dynamic-FDC (DDC) systems based on the 5G signal format (5G-FDC and 5G-DDC) have gained substantial attention for introducing in-band full-duplex (IBFD) into 5G. However, self-interference (SI) at a base station (BS) and inter-user interference (IUI) in user equipment (UE) are significant hurdles in implementing FDC and DDC systems. This study proposes an IUI cancellation (IUIC) scheme based on successive interference cancellation tailored to the signal configuration and channel coding of 5G. Additionally, we introduce user scheduling and adaptive modulation algorithms for 5G-DDC. We evaluate the proposed schemes using link- and system-level simulations. The results demonstrate a remarkable 40 dB reduction in IUI with a 3.4 dB decline in reception quality. Furthermore, our IUIC method reduces the IUI of close-distance UE pairs, expands the candidate UE pairs for IBFD operation, and significantly enhances the IBFD application ratio in the downlink slot by 51.0% compared to conventional 5G-DDC. Moreover, the gain of the uplink average throughput increases by 11.4% when the BS and UE transmission powers are at their maximum.
