面向语义信息直传的通信架构

Communication framework for directed transmission of informative semantic

随着聚焦提升带宽和频谱效率的传统通信发展模式渐入瓶颈,越来越多的研究将智能通信的目标从语法层转向语义层,通过感知并传输语义而非完整信号来节省带宽资源。信宿端智能体只需接收可理解语义中有信息部分即可。若能在信源端从语义角度中甄别出对信宿端有信息的部分加以传输,将进一步降低带宽资源和信宿端语义信息处理的时间和功耗。为此,首先探讨了智能体的语义信息处理和理解的过程,并将信宿从信息中感知到的语义划分为冗余语义、难以理解语义(暗语义)和有信息的语义(语信);接着,提出了面向传输语义中有信息的部分的通信范式——语信通信,并将通信范式划分为语法、语义、语信、语用四层;最后,通过仿真实验验证了语信通信的可行性和有效性。这为下一代通信范式的发展提供了新思路和技术牵引。

As the traditional communication development model focusing on enhancing bandwidth and spectrum efficiency is getting bottlenecked,more and more research is shifting the goal of intelligent communication from the syntactic level to the semantic level to save bandwidth resources by sensing and transmitting semantics rather than the complete signal.For the receiver agent,it is enough to receive only the information part of the understandable semantics.If the informative parts from the semantics can be filtered for transmission,it will further reduce the bandwidth resources and the time and power consumption of semantic information processing at the sender-side.To this end,firstly,the process of semantic information processing and comprehension of an intelligent body was explored.Secondly,the semantics perceived by the receiver from the message were classified into redundant semantics,unintelligible semantics,and informative semantic.Then,a communication paradigm oriented to transmitting the informative part of the semantics,called informative communication,was proposed,and the communication paradigm was extended to include four layers:syntax,semantic,informative,and pragmatic.Finally,the feasibility and effectiveness of informative communication were verified through simulation.This provides new ideas and technical traction for the development of next-generation communication models.
