In this embodiment, the first device can generate corresponding communication-sensing integrated signals for different sensing capabilities and different sensing service nodes. The generated OFDM-based sensing waveform has good compatibility with the communication system, high spectrum utilization rate, and higher sensing accuracy.

For example: The sensing process includes a coarse sensing process and a fine sensing process. In the coarse sensing process at the initial stage of sensing, the first device has not recognized the target object yet, so the frequency-domain resource occupancy factor can be determined based on the distance accuracy in the resource configuration information, and then the communication and sensing integrated signal can be generated in combination with the comb configuration parameters. In the fine sensing process, the first device has recognized the target object, so the frequency-domain resource occupancy factor can be determined based on the distance resolution in the resource configuration information, and then the communication and sensing integrated signal can be generated in combination with the comb configuration parameters. In this embodiment, for different situations of whether the target object is recognized or not, the communication and sensing integrated signal generated by the first device based on the distance accuracy may be different from the communication and sensing integrated signal generated based on the distance resolution.

[0161] Among them, γ is an algorithm factor, which can be an integer from 1 to 8; p is a system subcarrier adjustment factor, which is a positive integer. Optionally, the value of p corresponding to the NR system can be 3. The frequency domain resource occupancy factor is the smallest integer that satisfies the above formula.

[0162] As an optional embodiment, the value of the comb configuration parameter satisfies the interval formula of the comb configuration, and the value of the comb configuration parameter is within the first range;

[0163] The interval formula of the comb configuration is:

[0164]

[0165] where N comb represents the interval of the comb configuration; m is the comb configuration parameter; Δf is the subcarrier spacing; c is the speed of light; R max is the maximum detection distance.

[0166] In this embodiment, the first device determines the comb configuration parameter m of the communication and sensing integrated signal according to the maximum detection distance, and the first range can be pre-configured or predefined. m is a non-negative integer that satisfies the above formula and has a value within the first range. Optionally, m can be the smallest value that satisfies the above formula, that is, the value of m should not be too large.

[0180] In this embodiment, the resource configuration information may be generated by the first device itself or sent by the second device to the first device. For example: if the first device is a terminal and the second device is a base station, the base station generates the resource configuration information and sends it to the terminal, and the terminal generates and sends a communication sensing integrated signal based on the resource configuration information; or, if the first device is a base station, the base station generates the resource configuration information by itself and generates and sends a communication sensing integrated signal based on the resource configuration information. Among them, the method for the first device to generate resource configuration information is the same as the method for the second device to generate resource configuration information. The second device may also be a terminal, such as a terminal in a direct communication link or a vehicle-to-everything device.

Among them, for the case where no sensing target is recognized, the second device may determine the allocated sensing resources according to the range accuracy, the maximum detection range, and the comb configuration parameter to ensure the accuracy of parameter estimation in the process of identifying the target object.

[0182] For the case where a sensing target is recognized, the second device determines the allocated sensing resources through the range resolution, the maximum detection range, and the comb configuration parameter. The range resolution is the ability to distinguish two or more targets in the same azimuth but at different distances, and can affect the recognition probability and range estimation accuracy in the case of multiple targets. Therefore, for the case where a sensing target is recognized, allocating sensing resources based on the range resolution can ensure the multi-target recognition probability and the target recognition range accuracy. Optionally, the generating of the resource configuration information includes:

[0188] In this embodiment, the first device may determine the resource configuration information of the signal according to the range resolution or range accuracy and the comb configuration parameters of the communication-sensing integrated signal. Among them, for the case where no sensing target is recognized, the first device may determine the allocated sensing resources according to the range accuracy, the maximum detection range, and the comb configuration parameters to ensure the accuracy of parameter estimation in the process of recognizing the target object.
