摘要:

无人机在低空经济中发挥了重要作用,并已应用于各种场景。然而,随着无人机数量的增加和无线数据的爆炸性增长,现有的面向比特的通信网络已接近香农容量,无法满足面向比特的无人机通信网络中指挥控制(C&C)传输的超可靠低延迟通信(URLLC)服务质量(QoS)要求。为解决这一问题,我们提出了一种在有限无线资源下用于多无人机的语义感知C&C传输方案。具体地,我们利用语义相似度来测量每个无人机在连续传输时间间隔(TTI)内C&C消息的变化,并捕获无人机间C&C消息的相关性,从而实现多播传输。基于语义相似度和无人机命令的重要性,我们设计了一个触发函数来量化无人机的QoS。然后,为了最大化长期QoS并利用语义相似度带来的C&C消息多播机会,我们开发了一种近端策略优化(PPO)算法,以联合决定传输模式(单播/多播/空闲)以及基站(BS)与无人机之间有限资源块(RB)的分配。实验结果表明,与面向比特的无人机传输相比,我们提出的语义感知框架显著提高了传输效率和有效性。

英文摘要:

Uncrewed aerial vehicles (UAVs) have played an important role in the low-altitude economy and have been used in various applications. However, with the increasing number of UAVs and explosive wireless data, the existing bit-oriented communication network has approached the Shannon capacity, which cannot satisfy the quality of service (QoS) with ultra-reliable low-latency communication (URLLC) requirements for command and control (C\&C) transmission in bit-oriented UAV communication networks. To address this issue, we propose a novel semantic-aware C\&C transmission for multi-UAVs under limited wireless resources. Specifically, we leverage semantic similarity to measure the variation in C\&C messages for each UAV over continuous transmission time intervals (TTIs) and capture the correlation of C\&C messages among UAVs, enabling multicast transmission. Based on the semantic similarity and the importance of UAV commands, we design a trigger function to quantify the QoS of UAVs. Then, to maximize the long-term QoS and exploit multicast opportunities of C\&C messages induced by semantic similarity, we develop a proximal policy optimization (PPO) algorithm to jointly determine the transmission mode (unicast/multicast/idle) and the allocation of limited resource blocks (RBs) between a base station (BS) and UAVs. Experimental results show that our proposed semantic-aware framework significantly increases transmission efficiency and improves effectiveness compared with bit-oriented UAV transmission.
