Description

Communication method and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and a related device. Background With the development and progress of communication technology, in future cellular networks, a base station not only can realize interconnection of people and objects, but also has a sensing function, and an enabling technology for realizing coexistence, mutual assistance and reciprocity of the communication function and the sensing function is called communication sensing integration. With the advanced research and development of integrated communication (ISAC) INTEGRATED SENSING AND in academia and industry, the use of radio frequency signals of a communication system to perform sensing tasks is becoming an increasingly popular research direction. For example, the base station may be used as a transmitting end to send a sensing signal, and other base stations, transmission receiving points (transmission reception point, TRP), or terminal devices may be used as receiving ends and computing nodes to receive sensing signals reflected and scattered by objects in the environment, and determine sensing results according to the received sensing signals. But the perceived signal is a wireless signal in the communication system, and occupies wireless transmission resources (transmission resources for short) of the communication system. How to improve the accuracy of the sensing result under the condition of saving the transmission resources of the communication system so as to meet the requirements of sensing tasks becomes a problem to be solved urgently. Disclosure of Invention Through analysis, the accuracy of the sensing result is improved by expanding the time domain resource of the sensing signal sent by the transmitting end. In order to improve accuracy of the sensing result, the transmitting end may send the sensing signal in a fixed larger number (N is a positive integer greater than 1) of time domain resource units. It is assumed that when the transmitting end transmits the sensing signal in M (M is a positive integer greater than 1) time domain resource units, the accuracy of the sensing result just meets the requirement of the sensing task. When N is greater than M, time domain resources are wasted, and when N is less than M, accuracy of a sensing result may not meet requirements of a sensing task, and user experience is reduced. Therefore, the application provides a communication method and a related device, wherein after receiving a sensing signal, a receiving end informs a transmitting end of re-sensing the sensing signal or not re-sensing the sensing signal based on the sensing signal, thereby being beneficial to improving the accuracy of a sensing result under the condition of saving time domain resources. The scheme provided by the application is described below. In a first aspect, the present application provides a method of communication. The execution main body of the method is a receiving end, and the receiving end is used for receiving the sensing signal. The application is not limited to the type of receiving end, and for example, the receiving end may be a communication device in a communication system. The communication device may be a communication apparatus or may be a part of a component in a communication apparatus, where the part of the component may be a processor, a chip (or a chip system), a logic module, a software product, or the like. The present application is not limited to the type of communication device, and for example, the communication device may be a terminal or a network device. In the method, a receiving end receives a first sensing signal, wherein the first sensing signal is a sensing signal sent by a transmitting end at a first transmission resource, and the sensing signal is used for sensing the position of a target object. Then, the receiving end may send a first message based on the first sensing signal, where the first message includes first information or second information, where the first information indicates that a sensing result based on the first sensing signal does not meet a requirement, and the second information indicates that a sensing result based on the first sensing signal meets a requirement. The receiving end is beneficial to the meeting condition of the accuracy of the sensing result estimated based on the sensing signal on the requirement of the sensing task by executing the method, and the transmitting end is informed of re-sensing the sensing signal or not re-sensing the sensing signal based on the meeting condition. Therefore, the method is beneficial to informing the transmitting end of retransmitting the sensing signal when the accuracy does not meet the requirement (the number of the time domain resource units occupied by the sensing signal is smaller than M at the moment), and informing the transmitting end of not retransmitting
