[0068] The following is a brief introduction to some of the terms and related technologies involved in the embodiments of this application:

[0069] 1. Peak Spectrum Information: Peak spectrum information is information obtained by processing the echo signal of a sensed signal using specific signal processing methods. It contains target information about the target object, such as the distance between the target object and the sensing device, and the speed of the target object. In signal processing, peak spectrum information can refer to the signal's representation in the frequency domain or its representation in the time domain.

[0070] In frequency domain analysis, a signal is transformed from the time domain to the frequency domain using methods such as Fourier transform, at which point the spectral characteristics of the signal can be observed. In a spectrum graph, the horizontal axis represents frequency, and the vertical axis represents the amplitude or energy of the signal at that frequency. The "peaks" in peak spectral information refer to the maximum amplitude or highest energy within a frequency range; these peaks typically correspond to specific frequency components in the signal. Therefore, in frequency domain analysis, it reveals important characteristics of the signal in the frequency domain.

[0071] In time-domain analysis, signals are directly represented with time as the independent variable, and what can be observed is the waveform of the signal changing over time. In time-domain peak spectrum information, a "peak" refers to the maximum amplitude or highest energy within a time domain; these points reflect the strength or state of the signal at a specific point in time.

[0072] 2. Component Carrier (CC): A component carrier is the basic unit of carrier aggregation. All component carriers are integrated to provide higher data bandwidth for the terminal device. In cooperative sensing, sensing bandwidth and performance can also be improved by aggregating frequency domain resources used for sensing on different component carriers.

[0073] 3. Terminal equipment:

[0074] The terminal devices in this application embodiment may include handheld devices, vehicle-mounted devices, etc., that have wireless communication capabilities. For example, some terminal devices include: mobile phones, tablets, PDAs, laptops, mobile internet devices (MIDs), wearable devices, VR devices, AR devices, wireless terminal devices in industrial control, wireless terminal devices in self-driving, wireless terminal devices in remote medical surgery, wireless terminal devices in smart grids, wireless terminal devices in transportation safety, wireless terminal devices in smart cities, wireless terminal devices in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc., and the embodiments of this application are not limited to these.

[0075] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0076] The terminal equipment in this application embodiment can also be referred to as: user equipment (UE), mobile station (MS), mobile terminal equipment (MT), access terminal equipment, user unit, user station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, user terminal equipment, terminal equipment, wireless communication equipment, user agent, or user device, etc.

[0077] In this embodiment of the application, the device for implementing the function of the terminal device can be the terminal device itself; or it can be a device that enables the terminal device to implement the function, such as a chip system, which can be installed in the terminal device.

[0078] 4. Network equipment

[0079] The network device in this application embodiment can refer to a public mobile communication network device, which is an interface device for terminal devices to access the Internet. It is also a form of radio station, which refers to a radio transceiver station that transmits information with terminal devices in a certain radio coverage area. It includes a base station (BS), which can also be called a base station device. It is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in 2G networks, devices providing base station functionality include base transceiver stations (BTS); in 3G networks, devices providing base station functionality include NodeBs; in 4G networks, devices providing base station functionality include evolved NodeBs (eNBs); in wireless local area networks (WLANs), devices providing base station functionality are access points (APs); in 5G NR, devices providing base station functionality include gNBs and further evolved NodeBs (ng-eNBs). The gNB communicates with terminal devices using NR technology, while the ng-eNB communicates with terminal devices using evolved universal terrestrial radio access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network device 103 in this embodiment also includes devices providing base station functionality in future new data transmission systems.

[0080] In this embodiment of the application, the means for implementing the function of the network device can be the network device itself, or it can be a means that enables the network device to implement the function, such as a chip system, which can be installed in the network device.

[0081] In integrated sensing technologies within communication systems, two main approaches are employed: mono-static sensing systems and bi-static sensing systems. In a mono-static sensing system, both the transmitting and receiving antennas are located at the base station, or the base station antenna array transmits and receives signals in full-duplex mode. In a bi-static sensing system, the transmitting and receiving antennas are placed on different base stations or terminal devices. The signal transmitted by the base station is reflected by the target object and finally received by the sensor. However, these technologies lack collaborative sensing among multiple devices and the ability to interact with the obtained peak spectrum information.

[0082] Based on the above problems, the information interaction method, apparatus, and storage medium provided in this application embodiment acquire first peak spectrum information, which is obtained by a first device sensing a target object; receive second peak spectrum information from at least one second device, which is obtained for sensing the target object; and fuse N second peak spectrum information from the second peak spectrum information from at least one second device with the first peak spectrum information to obtain third peak spectrum information, where N is less than or equal to the total number of at least one second device. This enables multiple devices to simultaneously sense the same target object when the first and second devices perform sensing functions. Based on the cooperation of multiple devices, the interaction and fusion of peak spectrum information can improve the sensing performance of the target object.

[0083] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or identical content will not be repeated in different embodiments.

[0084] Reference Figure 1 The image provided in this application illustrates an application scenario for an information interaction method. Figure 1 As shown, it includes: a first network device 11, and at least one second network device (such as...). Figure 1The network includes a second network device 12 and a second network device 13, and a target object 14. The first network device and multiple second network devices sense the target object. Second network device 12 sends second peak spectrum information a1 to the first network device 11, and further, second network device 12 sends second component carrier configuration information b1 to the first network device 11. Second network device 13 sends second peak spectrum information a2 to the first network device 11, and further, second network device 13 sends second component carrier configuration information b2 to the first network device 11. Finally, the first network device 11 fuses the first peak spectrum information, the second peak spectrum information a1, and the second peak spectrum information a2 from the first network device to obtain third peak spectrum information.

[0085] Reference Figure 2 An image illustrating an application scenario of another information interaction method provided in this application, such as... Figure 2 As shown, it includes: a first terminal device 21, multiple second terminal devices (such as second terminal device 22 and second terminal device 23), and a target object 24. The first terminal device and the multiple second terminal devices perceive the target object. Figure 2 The second terminal device 22 sends the second peak spectrum information a3 to the first terminal device 21. Further, the second terminal device 22 sends the second component carrier configuration information b3 to the first terminal device 21. The second terminal device 23 sends the second peak spectrum information a4 to the first terminal device 21. Further, the second terminal device 23 sends the second component carrier configuration information b4 to the first terminal device 21. Finally, the first terminal device 21 fuses the first peak spectrum information, the second peak spectrum information a3, and the second peak spectrum information a4 of the first terminal device to obtain the third peak spectrum information.

[0086] Reference Figure 3 , Figure 3 This is a flowchart illustrating the steps of an information interaction method provided in the embodiments of this application. Figure 1 In some embodiments of this application, the executing entity of the information interaction method is a first device, which may be a network device or a terminal device (such as...). Figure 1 The first network device 11 shown or Figure 2 The first terminal device 21 shown can also be a device capable of supporting network devices or terminal devices to perform related functions, such as a chip system, which can be installed in network devices or terminal devices. The information interaction method includes the following steps:

[0087] S301, obtain the first peak spectrum information.

[0088] Among them, the first peak spectrum information is obtained by the first device sensing the target object.

[0089] In one embodiment, the first device uses a single static sensing method to sense the target object. The specific sensing process is as follows: a first sensing signal is sent to the target object, and then a first echo signal is received in response to the first sensing signal. The first echo signal can be processed, such as by FFT transformation, to obtain the first peak spectrum information.

[0090] In another embodiment, the first device can use a dual static sensing method to sense the target object, that is, another device sends a first sensing signal to the target object, the first device receives a first echo signal returned in response to the first sensing signal, and the first device performs signal processing on the first echo signal to obtain the first peak spectrum information.

[0091] In this application, the first device may also obtain the first peak spectrum information through other means, without limitation.

[0092] For example, it can be adopted Figure 4 The velocity domain peak spectrum shown represents peak spectrum information. Figure 4 The horizontal axis represents velocity in m / s (meters per second), and the vertical axis represents the normalized order of magnitude. Figure 4 In this context, the velocity value corresponding to the peak value is the velocity of the target object. Furthermore, peak spectrum information can also be represented using distance-domain peak spectra or angle-domain peak spectra, allowing the determination of the distance, direction, or velocity between the target object and the first device based on the peak spectrum information.

[0093] S302, receive second peak spectrum information from at least one second device.

[0094] Among them, the second peak spectrum information is obtained by the second device for the target object, and each second device obtains one second peak spectrum information.

[0095] In one embodiment, the second device can use a single static sensing method to sense the target object. The specific sensing process is as follows: a second sensing signal is sent to the target object, and then a second echo signal is received in response to the second sensing signal. The second echo signal can be processed, such as by FFT transformation, to obtain the second peak spectrum information.

[0096] In another embodiment, the second device may also use a dual static sensing method to sense the target object, that is, another device sends a second sensing signal to the target object, the second device receives a second echo signal returned in response to the second sensing signal, and the second device performs signal processing on the second echo signal to obtain the second peak spectrum information.

[0097] In this application, the second device may also obtain the second peak spectrum information through other means, without limitation.

[0098] Furthermore, referring to Figure 1 and Figure 2The second device can be a network device or a terminal device.

[0099] In this embodiment of the application, the second device and the second peak spectrum information are in one-to-one correspondence, for example, in Figure 1 In the process, the second network device 12 obtains the second peak spectrum information a1, and the second network device 13 obtains the second peak spectrum information a2.

[0100] Furthermore, it should be noted that in some other embodiments of this application, the first device may also obtain at least one second peak spectrum information from a network (such as a core network) or a server, wherein each second peak spectrum information is peak spectrum information perceived by the second device from the target object. For example, the second device may report the second peak spectrum information to the network, and the first device may obtain at least one second peak spectrum information by requesting the network to obtain at least one peak spectrum information perceived by the second device.

[0101] Of course, the second device sends the second peak spectrum information, and correspondingly, the first device receives the second peak spectrum information. For example, the second device can also send the second peak spectrum information to the first device through the link between the first and second devices. For instance, if both the first and second devices are terminal devices, the link between them is a side link. Or, if both the first and second devices are network devices, the link between them is a link between network devices.

[0102] S303, fuse N second peak spectrum information and first peak spectrum information from at least one second device to obtain third peak spectrum information.

[0103] Where N is less than or equal to the total number of at least one second device. It can be understood that if the total number of at least one second device is M, then the first device receives M second peak spectrum information. When N = M, the first device fuses the first peak spectrum information and all (M) received second peak spectrum information to obtain the third peak spectrum information. When N is less than M, the first device fuses the first peak spectrum information and a portion (N) of the received M second peak spectrum information. In this embodiment, N is an integer greater than or equal to 1.

[0104] In some embodiments, the N second peak spectrum information are second peak spectrum information from at least one second device that meets a certain condition. For example, these N second peak spectrum information come from the N second devices that are closer to the first device. Alternatively, these N second peak spectrum information can be N second peak spectrum information randomly selected from the second peak spectrum information from at least one second device.

[0105] In the embodiments of this application, the first peak spectrum information and the second peak spectrum information can be fused using any fusion method to obtain the third peak spectrum information. For example, the third peak spectrum information can be obtained by weighted averaging of the first peak spectrum information and the second peak spectrum information. Another example is to calculate the average value after zero-padding and / or smoothing the first and second peak spectrum information respectively. This application does not limit the fusion method of the first and second peak spectrum information.

[0106] For example, third-peak spectral information can be used to estimate sensing parameters. For instance, third-peak spectral information can be used to estimate one or more pieces of information about a target object, such as its position, angle, or velocity.

[0107] This application embodiment is based on collaborative perception of peak spectrum information. Multiple devices (first device and second device) can simultaneously perceive the same target object. The obtained peak spectrum information is aggregated on the first device, and multiple peak spectrum information (first peak spectrum information and second peak spectrum information) are fused on the first device to obtain the final third peak spectrum information, which can improve the perception performance of the target object.

[0108] Reference Figure 5 , Figure 5 This is a flowchart illustrating the steps of an information interaction method provided in the embodiments of this application. Figure 2 In some embodiments of this application, the executing entity of the information interaction method is a first device, and the information interaction method includes the following steps:

[0109] S501, obtain the first component carrier configuration information.

[0110] The first component carrier configuration information is used to configure the first sensing signal of the sensing target object so as to obtain the first peak spectrum information based on the first sensing signal.

[0111] Specifically, the first component carrier configuration information includes at least one of the following:

[0112] The identifier of the first component carrier used to sense the target object;

[0113] First radio frequency carrier frequency;

[0114] First subcarrier spacing;

[0115] The first time-domain symbol count and the first time-domain symbol interval;

[0116] The number of symbols in the first frequency domain and the symbol interval in the first frequency domain; or...

[0117] The first size of the sampled data.

[0118] In this embodiment, the first component carrier configuration information is configured by the core network device to the first device. Alternatively, the first device may obtain the first component carrier configuration information through other means. For example, if the first device is a terminal device, the first component carrier configuration information may also be sent to the first device by the access network device (such as a base station).

[0119] The first component carrier configuration information may include some or all of the items mentioned above. For example, when the first component carrier configuration information includes some of the items mentioned above, the first device can determine other items not included in the first component carrier configuration information based on prior information or relevant configurations in the protocol.

[0120] For example, if the first device has previously configured a first sensing signal based on the identifier of the first component carrier, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, the first number of frequency-domain symbols and the first frequency-domain symbol spacing, and the first size of the sampled data, then it can store the association relationship between the identifier of the first component carrier, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, the first number of frequency-domain symbols and the first frequency-domain symbol spacing, and the first size of the sampled data as prior information. If the current first component carrier configuration information only includes the identifier of the first component carrier, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, the first number of frequency-domain symbols and the first frequency-domain symbol spacing, and the first size of the sampled data that have a mapping relationship with the identifier of the first component carrier can be determined based on the prior information. Then, the first sensing signal can be configured based on the identifier of the first component carrier, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, the first number of frequency-domain symbols and the first frequency-domain symbol spacing, and the first size of the sampled data.

[0121] Alternatively, in some embodiments, if the first device has a mapping or association relationship between any of the following: the identifier of the first component carrier of the target object, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, the first number of frequency-domain symbols and the first frequency-domain symbol spacing, and the first size of the sampled data, then when the first device obtains the first component carrier configuration information which includes only one or more of these, it can determine other items based on the mapping or association relationship.

[0122] For example, the first component carrier configuration information includes: the identifier of the first component carrier used to sense the target object, the first radio frequency carrier frequency, the first subcarrier spacing, and the first size of the sampled data.

[0123] The identifier of the first component carrier is associated with the first time domain symbol number, the first time domain symbol interval, the first frequency domain symbol number, and the first frequency domain symbol interval.

[0124] Furthermore, when the first component carrier configuration information includes some of the aforementioned items, the remaining items can also be obtained through other means, without limitation.

[0125] Specifically, the first component carrier can be one or more, such as CC1 and CC2, where CC1 and CC2 are identified by identifier 1 and identifier 2 respectively. Identifier 1 and identifier 2 are both identifiers of the first component carrier. The first radio frequency carrier frequency is the radio frequency carrier frequency used by the first device to transmit the first sensing signal. Furthermore, the first subcarrier is the subcarrier used by the first device to transmit and receive signals. The first subcarrier spacing refers to the frequency spacing between adjacent first subcarriers in the frequency domain. The first time-domain symbol count is the number of time-domain symbols used by the first device to transmit and receive signals. The first time-domain symbol spacing is the time-domain symbol spacing used by the first device to transmit and receive signals. The first frequency-domain symbol count is the number of frequency-domain symbols used by the first device to transmit and receive signals, and the first frequency-domain symbol spacing is the frequency-domain symbol spacing used by the first device to transmit and receive signals. Specifically, the first size of the sampled data refers to the size of the data sampled each time the first echo signal is processed.

[0126] S502, send the first sensing signal.

[0127] In this embodiment, the first sensing signal is configured based on the first component carrier configuration information. That is, the first sensing signal is transmitted based on at least one of the first component carrier, the first radio frequency carrier frequency, the first subcarrier spacing, the first number of time-domain symbols and the first time-domain symbol spacing, or the first number of frequency-domain symbols or the first frequency-domain symbol spacing.

[0128] S503 receives the first echo signal returned.

[0129] In this process, the first device sends a first sensing signal to the target object, the target object reflects the first sensing signal to obtain a first echo signal, and the first device receives the first echo signal reflected by the target object.

[0130] S504 performs signal processing on the first echo signal to obtain the first peak spectrum information.

[0131] In some embodiments of this application, the first device may perform signal processing on the first echo signal based on one or more of Fourier transform, multiple signal classification algorithms, or any other spatial spectrum estimation transformation method to obtain first peak spectrum information. The specific method used for signal processing can be determined by the first device based on a predefined strategy, indicated by the network, or predefined through a protocol; this application does not limit this approach.

[0132] Specifically, based on the first size of the sampled data in the first component carrier configuration information, the first echo signal is sampled, and then signal processing is performed to obtain the first peak spectrum information.

[0133] S505, receive second component carrier configuration information from at least one second device.

[0134] The second component carrier configuration information is configured in the second device by the core network. Alternatively, in this embodiment, the second device may also obtain the second component carrier configuration information through other means.

[0135] The second component carrier configuration information is used to configure the second sensing signal. Specifically, the second device sends the second sensing signal to the target object based on the second component carrier, then receives the second echo signal of the second sensing signal, and determines the second peak spectrum information based on the second echo signal.

[0136] Specifically, the second component carrier configuration information includes at least one of the following:

[0137] The identifier of the second component carrier used to sense the target object;

[0138] Second radio frequency carrier frequency;

[0139] Second subcarrier spacing;

[0140] The second time-domain symbol count and the second time-domain symbol interval;

[0141] The number of symbols in the second frequency domain and the symbol interval in the second frequency domain; or...

[0142] The second size of the sampled data.

[0143] In this embodiment, the second component carrier configuration information is configured by the core network device to the second device. Alternatively, the second device can obtain the second component carrier configuration information through other means. For example, if the second device is a terminal device, the second component carrier configuration information can also be sent to the second device by the access network device (such as a base station).

[0144] In this embodiment, the received second component carrier configuration information may include some or all of the aforementioned items. For example, when including some items, the first device may determine other items not included in the first component carrier configuration information based on prior information or relevant configurations in the protocol.

[0145] For example, if the first device previously received second component carrier configuration information including the identifier of the second component carrier, the second radio frequency carrier frequency, the second subcarrier spacing, the second number of time-domain symbols and the second time-domain symbol spacing, the second number of frequency-domain symbols and the second frequency-domain symbol spacing, and the second size of the sampled data, then the association between the identifier of the second component carrier, the second radio frequency carrier frequency, the second subcarrier spacing, the second number of time-domain symbols and the second time-domain symbol spacing, the second number of frequency-domain symbols and the second frequency-domain symbol spacing, and the second size of the sampled data can be stored as prior information to configure the association relationship between the second sensing signal. If the currently received second component carrier configuration information only includes the identifier of the second component carrier, the second radio frequency carrier frequency, the second subcarrier spacing, the second number of time-domain symbols and the second time-domain symbol spacing, the second number of frequency-domain symbols and the second frequency-domain symbol spacing, and the second size of the sampled data that have a mapping relationship with the identifier of the second component carrier can be determined based on the prior information.

[0146] Alternatively, in some embodiments, if the target object's second component carrier identifier, second radio frequency carrier frequency, second subcarrier spacing, second time domain symbol number and second time domain symbol spacing, second frequency domain symbol number and second frequency domain symbol spacing and second size of sampled data are mapped or associated, then when the received second component carrier configuration information only includes one or more of these, the first device can determine other items based on the mapping or association relationship.

[0147] For example, the second component carrier configuration information includes: the identifier of the second component carrier used to sense the target object, the second radio frequency carrier frequency, the second subcarrier spacing, and the second size of the sampled data.

[0148] In this context, the identifier of the second component carrier is associated with the second time-domain symbol number, the second time-domain symbol interval, the second frequency-domain symbol number, and the second frequency-domain symbol interval.

[0149] Furthermore, when the second component carrier configuration information includes some of the aforementioned items, the remaining items can also be obtained through other means, without limitation.

[0150] Specifically, the second component carrier can be one or more, for example, second component carriers such as CC2 and CC3, where CC2 and CC3 are identifiers 2 and 3 respectively, and identifiers 2 and 3 are both identifiers of the second component carrier. The second radio frequency carrier frequency is the radio frequency carrier frequency used by the second device to transmit the second sensing signal. Furthermore, the second subcarrier is the subcarrier used by the second device to transmit and receive signals. The second subcarrier spacing refers to the frequency spacing between adjacent second subcarriers in the frequency domain. The second time-domain symbol number is the number of time-domain symbols used by the second device to transmit and receive signals. The second time-domain symbol spacing is the time-domain symbol spacing used by the second device to transmit and receive signals. The second frequency-domain symbol number is the number of frequency-domain symbols used by the second device to transmit and receive signals, and the second frequency-domain symbol spacing is the frequency-domain symbol spacing used by the second device to transmit and receive signals. Specifically, the second size of the sampled data refers to the size of the data sampled each time the second echo signal is processed.

[0151] In this embodiment, the second device sends the second component carrier configuration information to the first device. For example, the second device can send the second component carrier configuration information to the first device via a downlink control message or a shared data channel.

[0152] S506, receive second peak spectrum information from at least one second device.

[0153] In this embodiment, different second peak spectral information is sensed by different second devices. There is a one-to-one correspondence between the second peak spectral information and the second device.

[0154] Specifically, the second device sends a second sensing signal to the target object, the target object reflects the second sensing signal to obtain a second echo signal, and the second device receives the second echo signal reflected by the target object.

[0155] For example, the second device can sample the second echo signal based on the second size of the sampled data in the second component carrier configuration information, and then perform signal processing to obtain the second peak spectrum information.

[0156] In this embodiment, a second peak spectrum information is taken as an example. One way for the first device to obtain the second peak spectrum information is as follows: the second device sends the second peak spectrum information, and correspondingly, the first device receives the second peak spectrum information. For example, the second device can send the second peak spectrum information to the first device through a certain signaling or message (e.g., a downlink control message).

[0157] In this embodiment, the other first device obtains the second peak spectrum information by acquiring it from a network (such as a core network) or a server. For example, the first device sends a peak spectrum information acquisition request to the network (such as a core network) or a server, requesting peak spectrum information perceived by one or more second devices located within a first location range. The location of the second device within the first location range is less than or equal to a certain threshold relative to the location of the first device.

[0158] S507, based on the first component carrier configuration information and the second component carrier configuration information of N second devices among at least one second device, the first peak spectrum information and the N second peak spectrum information are fused to obtain the third peak spectrum information.

[0159] Among them, the N second peak spectrum information and the N second component carrier configuration information of the second device correspond one-to-one.

[0160] In this process, signal processing for different sub-bands generates peak spectrum information. Using this peak spectrum information and certain processing methods (such as weighted summation), new third peak spectrum information can be obtained. Since this third peak spectrum information contains signal characteristic information from multiple sub-bands, it can be used for more accurate parameter estimation. For example, in radar signal processing, the third peak spectrum information can be used to estimate parameters such as the velocity, range, and angle (relative to the base station) of a target object. By utilizing the rich information in the third peak spectrum, the accuracy and reliability of parameter estimation can be significantly improved.

[0161] Specifically, the component carrier configuration information of different devices that implement cooperative sensing may be different. For example, different devices may use different frequency domain bandwidths and different frequency domain subcarrier intervals for sensing, which brings great challenges to the fusion of peak spectrum information for cooperative sensing. This application fuses the first peak spectrum information and the second component carrier configuration information of N second devices in at least one second device to obtain the third peak spectrum information, which can support cooperative sensing of multiple devices under the condition of using different component carrier configuration information.

[0162] In the embodiments of this application, the specific fusion method is not limited.

[0163] This application uses first component carrier configuration information and second component carrier configuration information, which can achieve better fusion of first peak spectrum information and second peak spectrum information to obtain more accurate third peak spectrum information.

[0164] S508, determine the location information of the target object based on the third peak spectrum information.

[0165] The location information includes at least one of the following:

[0166] The spatial coordinates of the target object;

[0167] The distance between the target object and the first device;

[0168] The distance between the target object and the second device;

[0169] The orientation of the target object relative to the first device; or,

[0170] The orientation of the target object relative to the second device.

[0171] For example, the peak value in the third peak spectrum information is determined, and the location information corresponding to the peak value is determined using some mathematical mapping methods. This application does not limit the specific process of determining the location information of the target object based on the third peak spectrum information.

[0172] In this embodiment, the first device can interact with the second device to obtain the second component carrier configuration information configured by the network for the second device. Based on its own configured first and second component carrier configuration information, the first device can fuse various peak spectrum information to achieve peak spectrum-level cooperative perception.

[0173] It is understood that, in the embodiments of this application, reference is made to... Figure 1 The process involves multiple network devices (a first network device and a second network device, such as a base station) performing mono-static sensing on the target object, with the first network device aggregating the data to obtain the third peak spectrum information. Specifically, each second network device sends its own sensed second peak spectrum information and second component carrier configuration information. The first network device then performs peak spectrum-level cooperative sensing (fusion of peak spectrum information) based on this second peak spectrum information, second component carrier configuration information, and its own first peak spectrum information and first component carrier configuration information to obtain the third peak spectrum information.

[0174] Reference Figure 2 Multiple terminal devices perform mono-static perception of the target object, and the third peak spectrum information is obtained by aggregating the data on the first terminal device, thus realizing peak spectrum-level collaborative perception.

[0175] In summary, this application achieves accurate positioning of the target object by acquiring first peak spectrum information, which is obtained by a first device sensing the target object; receiving second peak spectrum information from at least one second device, which is obtained by sensing the target object; and fusing N second peak spectrum information from the second peak spectrum information from at least one second device with the first peak spectrum information, where N is less than or equal to the total number of at least one second device. This enables the fusion of multiple peak spectrum information obtained from multiple devices to obtain the third peak spectrum information, the collaborative sensing of multiple devices, and the interaction of the sensed peak spectrum information.

[0177] S601, obtain the second peak spectrum information.

[0178] The second peak spectrum information is obtained by the second device sensing the target object.

[0179] In the embodiments of this application, reference is made to Figure 1 and Figure 2 The second device can be a network device or a terminal device. Different second peak spectrum information is perceived by different second devices. There is a one-to-one correspondence between the second peak spectrum information and the second device.

[0180] Specifically, the second device sends a second sensing signal to the target object, the target object reflects the second sensing signal to obtain a second echo signal, and the second device receives the second echo signal reflected by the target object.

[0181] In some embodiments, the second echo signal is sampled based on the second size of the sampled data in the second component carrier configuration information, and then signal processing is performed to obtain the second peak spectrum information. Furthermore, this application may also perform signal processing on the second echo signal in other ways to obtain the second peak spectrum information, without limitation.

[0182] In this embodiment, the second device sends the second peak spectrum information and the second component carrier configuration information to the first device via sensing information. That is, the second device sends sensing information to the first device, which includes the second peak spectrum information and the second component carrier configuration information.

[0184] The specific implementation process of the second device sending the second peak spectrum information to the first device can be referred to in S506, and will not be repeated here.

[0185] In this embodiment of the application, after the second device senses the second peak spectrum information, it sends the second peak spectrum information to the first device, so that the first device can fuse the peak spectrum information to realize the collaborative sensing of multiple devices and the interaction of the sensed peak spectrum information, which can improve the sensing performance of the target object.

[0200] It is understood that there is no necessary order between S706 and S702 to S705. The second component carrier configuration information can be sent before or after S702, and can be sent separately from or together with the second peak spectrum information. This application does not limit the timing of sending the second component carrier configuration information.

In another embodiment, the second device may send signaling to the first device, the signaling carrying second peak spectrum information and second component carrier configuration information; this is not limited.

[0203] In one embodiment, the second peak spectrum information is transmitted via a link between the first device and the second device. It can be understood that, when both the first device and the second device are network devices, reference is made to... Figure 1 The second peak spectrum information and / or the second component carrier configuration information are sent to the first device through the link between the first network device and the second network device.

Figure 2 The second peak spectrum information and / or the second component carrier configuration information are sent to the first device through the sidelink between the first device and the second device.

[0205] In one embodiment, the second peak spectrum information is transmitted via forwarding through the sensing function of the core network device, wherein both the first and second devices are network devices or both are terminal devices. The second device sends the second peak spectrum information and / or the second component carrier configuration information to the sensing function (SF) of the core network device, and then the sensing function of the core network device sends the second peak spectrum information and / or the second component carrier configuration information to the first device.

[0206] In this embodiment of the application, the sensing function of the core network device is a network element or functional node in the core network device.
