[0156] 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 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.

[0157] In the 6G network, there are demand scenarios that the traditional data-oriented communication mode is difficult to meet. For example, the emergence of 6G new services (such as Metaverse services) requires 6G networks to support wireless transmission of a large amount of data; 6G applications with a large number of nodes (such as collaborative robots and super-intelligent Internet of Things) require 6G networks to provide fast system response and reliable and efficient information interaction; more network resources in 6G networks need to be used for real-time updating of information and analysis of user data to ensure that 6G networks can provide better service experience.

[0158] The development of semantic communication and the promotion of 6G are complementary. On the one hand, the availability and connectivity of distributed computing and AI networks everywhere 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, so the development of 6G networks can provide a good network foundation for semantic communication, and the successful development of semantic communication can fully realize the vision of 6G.

[0159] By developing semantic communication, not only can the wireless data transmission burden of 6G networks be reduced, but also the efficiency of 6G network management and control can be improved, and semantic information can be used to design effective network resource allocation schemes for 6G.

[0160] In some embodiments, a semantic communication system can be divided into four types: classic semantic communication, semantic-oriented communication, goal-oriented communication, and semantic-aware communication.

[0161] 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.

[0162] In some embodiments, semantic-oriented communication can use semantic information reconstruction to reconstruct the original data.

[0163] In some embodiments, the target-oriented communication can utilize 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 directly map the semantic features to channel input symbols after being encoded by a joint source channel and received by the receiver, which can directly utilize the decoded semantic features to complete the task.

[0164] In some embodiments, semantic-aware communication can achieve data processing according to information context and perception of the environment to adapt to different communication needs.

[0165] For semantic communication, not only the reliable transmission of data itself is concerned, but also whether the receiver can make correct decisions and perform expected tasks after receiving the information. The core of semantic communication lies in extracting semantic information from data and saving bandwidth resources through efficient transmission methods to improve network capacity and communication efficiency. Non-semantic communication usually refers to traditional communication methods, which mainly focus on accurate transmission of data without special consideration of the semantic content of data.

[0166] In the communication process, the semantic communication sender can adopt a semantic communication method or a non-semantic communication method to send data according to the current business needs. However, if the communication performance is degraded or the system fails (for example, when the error rate of semantic decoding is detected to exceed a predetermined limit), the semantic communication system needs to be able to flexibly switch to another communication mode to maintain the stability and reliability of data transmission.

[0294] In some embodiments, the third indication information can be sent by the fourth communication device to the first communication device.

[0295] In some embodiments, the third indication information is used to indicate the communication data for which the first communication device switches between semantic communication and non-semantic communication.

[0296] In some embodiments, the first communication device can receive the third indication information sent by the fourth communication device, to determine, according to an indication of the third indication information, for which part of the communication data the switching is performed.

[0297] In some embodiments, the fourth communication device for indicating the second indication information and the fourth communication device for indicating the third indication information can be the same or different, and the embodiments of the present disclosure do not limit this.

[0298] In some embodiments, the communication data for which the switching is performed is communication data satisfying a corresponding condition, and the communication data for which the switching is performed can be at least one of communication data with channel decoding accuracy satisfying a fifth threshold, communication data with semantic accuracy satisfying a sixth threshold, communication data with semantic importance satisfying a seventh threshold, communication data with semantic information amount satisfying an eighth threshold, and communication data with semantic freshness satisfying a ninth threshold, but the present disclosure is not limited thereto.

[0299] In some embodiments, semantic importance (Value of Information, VoI) can be used to indicate the relevance of semantic information to a semantic communication process, for example, the semantic importance can be used to indicate the relevance of semantic information to a semantic reconstruction process, for example, the semantic importance can be used to indicate the relevance of semantic information to the execution of a semantic processing task, and the like, but the present disclosure is not limited thereto.

[0300] In some embodiments, the semantic information amount can be used to indicate the amount of information carried by the semantic information and the effectiveness of the amount of information carried by the semantic information, and the like, but the present disclosure is not limited thereto.

[0301] In some embodiments, the semantic freshness can be used to indicate the degree of obsolescence of the semantic information. Optionally, the semantic freshness can be used to indicate the degree of obsolescence of the semantic information received by the semantic communication receiving end device or any intermediate transmission node located between the semantic communication sending end device and the semantic communication receiving end device. For example, the semantic freshness can be defined as the difference between the time (i.e., the current time) of receiving the semantic information and the data packet timestamp, which can be used to indicate the generation time of the data packet, but is not limited thereto.

[0302] In some embodiments, the fifth threshold value is agreed upon by the protocol, or the fifth threshold value is indicated by the fifth communication device, or the fifth threshold value is determined by the first communication device.
