[0149] Semantic communication can deliver the most relevant information to all communication participants after pre-processing the data based on artificial intelligence technology, thereby reducing network burden. Semantic communication can achieve higher level of intelligent communication in terms of semantics and effectiveness, and change the communication nodes from simple symbol exchange senders and receivers to more intelligent agents to exchange the semantic part of the data in the communication process, thereby efficiently achieving the communication goal.

[0150] The development of semantic communication and the promotion of 6G are complementary. On the one hand, the availability and connectivity of distributed computing and ubiquitous AI networks in 6G will enable semantic communication to be deployed on a large scale, and on the other hand, semantic communication overcomes the limitations of traditional communication and can greatly improve network performance. Therefore, the development of 6G network can provide a good network foundation for semantic communication, and the successful development of semantic communication can fully realize the vision of 6G.

[0151] By developing semantic communication, not only can the wireless data transmission burden of 6G network be reduced, but also the network management efficiency can be improved, and semantic information can be used to design effective network resource allocation schemes for 6G.

[0152] In some embodiments, a semantic communication system can be divided into four types: classic semantic communication, semantic-oriented communication, target-oriented communication, and semantic-aware communication.

[0153] In some embodiments, classic semantic communication mainly focuses on data transmission, and focuses on the accuracy of each bit and each symbol, and all bits and symbols are equally important.

[0154] In some embodiments, semantic-oriented communication can use semantic information reconstruction to reconstruct the original data.

[0155] In some embodiments, target-oriented communication can use semantic information to complete intelligent communication tasks, including but not limited to image retrieval, speech recognition, scene classification, etc. In the process of target-oriented semantic communication, semantic features serving intelligent tasks in the source data can be extracted to map the semantic features to channel inputs after joint source-channel coding, and the receiving end can directly use the decoded semantic features to complete the task.

[0156] In some embodiments, semantic-aware communication can achieve data processing according to information context and environmental perception to adapt to different communication needs.

[0157] In some embodiments, semantic communication tasks can be processed through a semantic communication module. Optionally, the semantic communication module can undertake the processing task of semantic information during transmission to reduce the amount of data transmission in the semantic communication process and improve transmission efficiency.

[0158] In some embodiments, the semantic communication module can be deployed at the UE side or the network side (such as gNB, CN, etc.).

[0159] In some embodiments, the semantic communication module can include a semantic processor (SP), a semantic database (SD), a semantic control (SC) module, and a semantic security gateway (SSG).

[0160] In some embodiments, the semantic processor can be used to implement the processing of semantic information. The semantic processor can extract semantic information from the compressed transmission data through an AI model, remove non-critical information in the transmission data, and only retain the most semantically valuable elements, thereby reducing the amount of data transmission in the communication process and improving transmission efficiency.

[0161] In some embodiments, the semantic processor can directly interact with the data source, receive raw communication data, and send processed information to the user side, while also being able to receive feedback information for continuously optimizing and adjusting the semantic analysis strategy and data processing strategy of the semantic processor.

[0162] In some embodiments, the semantic database can be used to store and manage semantic data processing model (such as deep neural network model) parameters and related configuration information, and can also be used to store processed data information (which can be key information extracted by the semantic processor or other processed semantic representation forms), and can also be used to provide a query interface so that the semantic processor can retrieve and obtain model parameters, configuration information, or semantic knowledge stored in the database. Optionally, the query interface can support dynamic loading, updating, and configuration of the semantic processor, thereby realizing flexible semantic processing capabilities.

[0163] In some embodiments, the semantic database can interact with the semantic processor to provide the semantic processor with data information processing models or related configurations, and the semantic database can store data information processed by the semantic processor. In addition, when other parts of the semantic communication system or external applications need to access the data stored in the semantic database, the semantic database can provide data retrieval functions and data access interfaces.

[0164] In some embodiments, the semantic control module can provide access control functions. Optionally, the semantic control module can be responsible for user access control, so as to select a base station with corresponding computing capability for the user to access when the user needs to perform semantic communication instead of a traditional communication process and needs to access a cell; the semantic control module can also be responsible for access control to the gNB, i.e., determining whether to respond to a semantic processing transmission request from the network side based on its own capability and processing data.

[0165] In some embodiments, if different tasks of different sources are to be performed, the semantic control module can also be used to select a corresponding information processing model or related configuration in the semantic database for better semantic communication.

[0166] In some embodiments, the semantic control module can also be used for optimizing network configuration and resource management. Optionally, the gNB can optimize the performance and response capability of the entire network, dynamically schedule and allocate resources, monitor and manage the quality of service, make dynamic negotiation and decision, and detect and recover faults according to the semantic information extracted by the semantic control module, so as to realize intelligent resource utilization, performance optimization and user demand satisfaction.

[0167] In some embodiments, the semantic control module can interact with the user to receive the user's access request and identify the user's needs (including but not limited to the user's semantic communication needs and the requirement for computing capability). Through the interaction with the user, the semantic control module can determine the user's access authority and select a base station suitable for the user's needs. In addition, the semantic control module can also interact with the semantic database module to obtain information about information processing models and related configurations.

[0168] In some embodiments, the semantic security gateway can be used to protect the security and privacy of semantic communication. Optionally, the semantic security gateway can perform encryption of semantic data, access control and other security mechanisms to ensure the confidentiality and integrity of semantic information; in addition, the semantic security gateway can detect malicious behavior, sensitive information and security threats by analyzing the semantic content of the data, and take corresponding security measures to protect the security and privacy of the network and the user.

[0169] In some embodiments, the semantic security gateway can be located in the gNB or the UE.

[0170] In some embodiments, the semantic security gateway can directly interact with the semantic information after semantic processing. Unlike traditional security gateways, the semantic security gateway adds security mechanisms such as data encryption, identity verification and access control from the semantic point of view, and can protect the security mechanisms from the transmission content by performing simple semantic analysis.

[0171] Referring to FIG. 2, FIG. 2 is an interaction process diagram of a semantic communication module of an access network according to an embodiment of the present disclosure. As shown in FIG. 2, after the terminal triggers a user access request, the terminal can send the access request to the CU, so as to realize semantic access control of the user through the semantic control module, so that the terminal can realize semantic communication with the network side after access. In the semantic communication process, the DU / CU can receive communication data from a data source, so as to interact with the semantic database through the semantic control module based on the received communication data, so as to realize model search and query, and then realize selection of a semantic model for better semantic communication. After the semantic model suitable for semantic communication is selected, the communication data received by the DU / CU can be processed through the semantic processor based on the selected semantic model, so as to realize extraction of semantic information, and the semantic information extracted by the semantic processor can be stored through the semantic database. In addition, in the semantic communication process, the semantic security gateway can be used to realize network management and forwarding functions.

[0172] In the semantic communication of different sources and different tasks, the semantic control module needs to select a corresponding information processing model or related configuration from the semantic database. How to assist the semantic control module to effectively select and configure the model so as to more accurately select and configure the model suitable for the current task and source, and thus realize more effective semantic communication, is a problem that needs to be considered.
