Description

Communication method, communication device and communication system The present application is a divisional application, the application number of the original application is 202411607339.8, the original application date is 2024, 11 and 12, and the whole content of the original application is incorporated by reference. Technical Field The present application relates to the field of communications technologies, and in particular, to a communication method, a communication device, and a communication system. Background In a communication awareness integrated scenario, a device may contain multiple modules, or support multiple awareness modes. For example, a device for star flash location (SPARKLINK POSITIONING, SLP) includes a star flash link low power (SPARKLINK LOW-energy, SLE) module and an SLP module (i.e., the SLP device supports both perceived modes of SLB and SLP). SLE and SLP can support human body perception, wherein the SLE-based sensing has the characteristics of low power consumption and narrow bandwidth, and the SLP-based sensing has the characteristics of high power consumption, large bandwidth and high measurement accuracy. For devices supporting multiple sensing modes, a proper sensing mode can be selected for sensing measurement so as to better adapt to sensing tasks and save power consumption. In general, for two devices supporting the same sensing mode, the performed sensing procedure may include several phases of sensing capability interaction, sensing measurement session establishment (or sensing configuration), sensing measurement interaction (or sensing measurement), and sensing measurement session closure (or sensing termination). However, in the stage of performing the sensing measurement interaction, if there is a situation that the sensing mode needs to be switched, the current sensing measurement needs to be ended, and the sensing process is re-performed once, such as renegotiating sensing parameters, configuring sensing parameters, and the like. Obviously, in a scene of needing to switch the sensing mode for multiple times, the sensing parameters need to be renegotiated for multiple times, and each time of switching needs to be reconfigured, so that the efficiency and flexibility of switching the sensing mode are low, and the caused system overhead is large. Therefore, how to improve the efficiency and flexibility of switching the sensing modes in the case that the device supports multiple sensing modes is a problem to be solved. Disclosure of Invention The application provides a communication method, a communication device and a communication system, which are used for improving the efficiency and flexibility of perception measurement. In a first aspect, an embodiment of the present application provides a communication method, where the method may be applied to a first device, or a component of the first device (such as a processor, a chip, or a chip system, or a system on a chip, or a logic node, a logic module, or software that can implement all or part of a function of the first device, or an apparatus that is used in cooperation with the first device. Taking the first device as an example, the method comprises the steps that the first device detects that the requirement of switching the sensing mode exists in the process of executing sensing measurement by adopting a first sensing mode and a second device, and the first device sends first information to the second device based on the requirement, wherein the first information is used for indicating the second device to switch the sensing mode. In an embodiment of the present application, the first device detects that there is a need to switch the sensing mode, which may include, but is not limited to, any one or more of the following: (1) The first device detects a sensing signal or a sensing scene change; for example, the first device (e.g. the sensing node) determines that the sensing mode needs to be switched when detecting that the current variation of the sensing signal reaches a set threshold, or determines that the sensing mode needs to be switched when detecting that the user enters a room. (2) The first equipment detects that the sensing task changes; the change of the sensing task may include a change of a level of the sensing task, a change of accuracy of the sensing task, and the like. For example, if the first device (e.g., the sensing node) detects that the level of the sensing task is high or the accuracy requirement of the sensing task is high, it confirms that the sensing mode needs to be switched. (3) The first device detecting that the perceived measurement is disturbed; For example, if the first device (e.g., a sensing node) detects that there is signal interference on the currently measured channel or frequency bin, it confirms that the sensing mode needs to be switched. (4) The first device detects a perceived air interface resource change. For example, if the first device (e.g. the sensing node) detects
