Current network technologies evolve toward the sixth generation of mobile communications (6G) systems. To achieve the performance requirements of high data rate, low latency, and massive connection, full-duplex (FD) wireless communication is one possible solution to provide high throughput and channel utilization. However, it is difficult to do so for legacy communication nodes. A distributed fairness-aware full-duplex dual-hop link scheduling algorithm, named weighted full duplex (W-FD), is proposed to achieve the efficient node selection and dynamic relay probing. The scheduling weight that considered traffic load, mutual interference, and response interval is employed to ensure link load balance. A node with a higher scheduling weight in the neighborhood is selected as the link establishment object to build a full-duplex link. Better than conventional half-duplex(HD) link scheduling, W-FD reduces link scheduling interval and ensures the access opportunities for legacy nodes. Simulation result shows that throughput and delay performance are improved. Compared with the existed full-duplex link scheduling, W-FD could better reflect the fairness of scheduling in multi-nodes and asymmetric-packets networks, and ensure the throughput and delay performance.

6G网络公平感知分布式双跳异构半双工链路调度

当前的网络技术向第六代移动通信 (6G) 系统发展。为了实现高数据速率、低延迟和海量连接的性能要求，全双工 (FD) 无线通信是提供高吞吐量和信道利用率的一种可能的解决方案。然而，对于传统的通信节点来说，这样做是很困难的。为了实现高效的节点选择和动态中继探测，提出了一种分布式公平感知全双工双跳链路调度算法，称为加权全双工（W-FD）。采用考虑流量负载、相互干扰和响应间隔的调度权重来保证链路负载均衡。选择邻域内调度权重较高的节点作为链路建立对象，建立全双工链路。W-FD优于传统的半双工（HD）链路调度，减少了链路调度间隔并确保了遗留节点的接入机会。仿真结果表明，吞吐量和延迟性能都有所提高。与现有的全双工链路调度相比，W-FD更能体现多节点和非对称分组网络中调度的公平性，保证吞吐量和时延性能。
