摘　　要：现有以香农信息论为基础的现代无线通信技术已经无法满足爆发式增长的数据传输需求,以“达意”为目标的语义通信有望突破香农极限的约束。面向蜂窝语义通信系统,分析传统蜂窝网络资源分配以及基于语义的无线资源分配通信范式、性能收益,研究资源分配模型的有效性、可靠性、频谱效率以及传输效率,从可分配的资源和性能评价这两个角度分别研究了传统蜂窝网络和语义通信网络资源分配的优化目标,归纳整理了现有语义通信资源分配方案的应用场景及研究方法。The existing modern wireless communication technology based on Shannon information theory can no longer meet the explosive growth in data transmission demand.Semantic communication with the aim of conveying meaning is expected to break through the constraints of Shannon's limit.This paper focuses on cellular semantic communication systems and analyzes the communication paradigm and performance benefits of traditional cellular network resource allocation and semantic-based wireless resource allocation.Then the resource allocation models are studied in terms of the effectiveness,reliability,spectral efficiency,and transmission efficiency.The optimization goals of resource allocation in traditional cellular networks and semantic communication networks are investigated from the perspectives of allocable resources and performance evaluation.Finally,the application scenarios and research methods are summarized for the existing semantic communication resource allocation schemes.
