A common scenario in the communication and sensing integrated technology is that a base station spontaneously receives, i.e. the base station sends a sensing signal and receives the sensing signal reflected or scattered by the surrounding environment. However, in this scenario, the base station is limited in viewing angle and has poor perceived performance. Disclosure of Invention The application provides a sensing method and a sensing device, which can improve the sensing performance. In a first aspect, a communication method is provided, which may be performed by a first terminal, or a component of the first terminal, for example, a processor, a chip, or a system-on-chip of the first terminal, or a logic module or software capable of implementing all or part of the functions of the first terminal. The method comprises the steps of receiving sensing signal configuration information from a Radio Access Network (RAN) node, wherein the sensing signal configuration information is used for configuring sensing resources, sending or receiving sensing signals on the sensing resources, and determining sensing results according to measurement results corresponding to the sensing signals and the position of a first terminal, wherein the position of the first terminal is fixed. Based on the scheme, the fixed-position terminal can send or receive the sensing signal on the sensing resource, namely, compared with the sensing mode of self-receiving by the base station, the fixed-position terminal is introduced to assist sensing, so that the RAN node and the fixed-position terminal can perform network end cooperative sensing, further more visual angles can be provided, and sensing performance is improved. For example, based on more perceived perspectives, a perceived target can be more fully imaged or a moving target can be perceived more accurately, such as a fixed-position terminal can provide a fixed position reference such that the perception of the moving target is enhanced. In addition, because the position of the terminal is fixed, the position of the terminal cannot change along with time, the accurate position of the terminal can be accurately obtained when the perception result is determined, and the problem that the perception precision is low due to the fact that the position of the mobile terminal is difficult to obtain or the position is inaccurate when the mobile terminal is adopted for assisting in perception is avoided, so that the perception performance is further improved. In one possible design, the method further comprises determining measurement results corresponding to the sensing signals according to the sensing signals, and sending the measurement results corresponding to the sensing signals to the sensing network element. Based on the possible design, the terminal can provide more visual angles for perception compared with the self-receiving of the RAN node based on the measurement result obtained by the perception signal, thereby improving the perception performance. For example, taking an environment reconstruction use case as an example, more visual angles can help the sensing network element to perform more complete imaging on the sensing target, or perform more accurate reconstruction on the environment, taking a g
