For communication systems that can provide awareness services, there is a need for an awareness device to provide awareness data to another device. When the sensing device provides sensing data to another device, how to ensure accuracy of the sensing data becomes a technical problem to be solved. Disclosure of Invention The application provides a communication method and a communication device, which are used for improving the accuracy of transmitted perception data. In a first aspect, the present application provides a communication method, which may be executed by a first communication device, where the communication device may be, for example, a network device or an access network device or a terminal, and in the case where no special explanation is made, the communication device of the present application may refer to the communication device itself, or may be a component in the communication device (for example, a processor, a circuit, a chip, or a chip system, etc.), or may also be a logic module or software capable of implementing all or part of functions of the network device or the access network device or the terminal, where the first communication device itself is exemplified by a first communication device, and the communication method includes transmitting perception data through P frequency domain resources, where P frequency domain resources are different in perception data, where P is a positive integer greater than or equal to 1, and where the transmission of perception data through P frequency domain resources includes, for a first frequency domain resource in P frequency domain resources, transmitting first perception data through the first frequency domain resources, and, if first acknowledgement information is received, transmitting second perception data through the first frequency domain resources or stopping transmission of perception data through the first frequency domain resources, and if the first acknowledgement information is received, the first acknowledgement information is used to indicate that the first frequency domain resources are not successfully transmitted in the first frequency domain resources, and if the first frequency domain resources are not successfully transmitted in the first frequency domain resources, and the first frequency domain resources are not successfully received. In the present application, a device that receives the perceived data transmitted by the first communication device through P frequency domain resources is referred to as a second communication device.
