[0024] The technical solutions in the present disclosure will be clearly and completely described below with reference to the drawings in the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present disclosure.

[0025] It should be noted that in the present disclosure, the expressions such as "exemplarily" or "for example" are used to represent as an example, illustration or description.

In addition, "at least one" means one or more, and "multiple" means two or more.

[0028] At present, a base station or a terminal can transmit a wireless signal, and receive a wireless signal reflected by an object to determine information of the object, and realize communication sensing.

[0029] However, in the above method, directly reporting the information of the object has the problem of occupying more transmission resources.

[0030] To solve the above technical problems, the present disclosure provides an information reporting method, executed by a first node, comprising: reporting difference data to a sensing network element; the difference data comprises a difference between sensing data and reference data; the sensing data comprises data of a sensing object obtained by measuring a sensing signal received by the first node. Since the difference data is the difference between the sensing data and the reference data, the difference value is smaller than the sensing data value, so as to reduce the resource overhead of reporting.

[0031] The information reporting method provided by the embodiments of the present disclosure can be applied to an information reporting system as shown in FIG. 1, as shown in FIG. 1, the information reporting system comprises a first node 101, a sensing network element 102 and a sensing object 103.

[0032] The first node 101 is configured to receive a wireless signal reflected by the sensing object 103 to obtain sensing data of the sensing object 103, or to send the sensing data to the sensing network element 102.

[0033] The sensing network element 102 is configured to receive the sensing data sent by the first node 101.

[0034] The sensing object 103 is an object to be sensed and is capable of reflecting a wireless signal.

[0035] In some embodiments, the first node 101 can be a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, and a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) \ virtual reality (VR) device, and the like. The detailed form of the first node is not specially limited in the embodiments of the present disclosure. The first node can interact with a user through one or more of a keyboard, a touchpad, a touch screen, a remote controller, voice interaction, a handwriting device, and the like.

[0036] It should be noted that FIG. 1 is only an exemplary framework diagram, and the number of devices included in FIG. 1 and the names of the devices are not limited.

[0037] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are used to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those skilled in the art can know that, with the evolution of network architecture and the appearance of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0038] The information reporting method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0039] The information reporting method provided by the embodiments of the present disclosure can be executed by the first node 101 in the information reporting system shown in FIG. 1. FIG. 2 shows a flowchart of an information reporting method. As shown in FIG. 2, the information reporting method includes S201.

[0040] S201, report difference data to a sensing network element.

[0041] The difference data includes a difference between sensing data and reference data. The sensing data includes data of a sensing object obtained by measuring a sensing signal received by the first node.

[0042] It should be understood that by emitting a sensing signal into a space where the sensing object is located, the sensing object reflects the sensing signal, and by measuring the sensing signal, sensing data containing information of the sensing object can be obtained.

[0043] In some embodiments, the sensing signal can be emitted by the first node or by the second node. The first node emitting and receiving the sensing signal can be referred to as self-emission and self-reception of the first node. The second node emitting the sensing signal and the first node receiving the sensing signal can be referred to as self-reception of the first node.

[0044] In some embodiments, when the first node is self-emission and self-reception, the sensing object is located within the signal coverage range of the first node. When the first node is self-reception, the first node is located within the signal coverage range of the node emitting the sensing signal.

[0045] In some embodiments, the first node or the second node can be a base station or a terminal. In this way, the process of communication sensing can be that the base station emits the sensing signal and the terminal receives the sensing signal. Or the base station emits the sensing signal and the base station receives the sensing signal. Or the terminal emits the sensing signal and the base station receives the sensing signal. Or the terminal emits the sensing signal and the terminal receives the sensing signal. The device receiving the sensing signal is the first node.

[0046] For example, when the sensing signal is transmitted by the first node and the first node is the base station A, the process of communication sensing can be: the base station B transmits the sensing signal, the base station A receives the sensing signal or the terminal transmits the sensing signal, and the base station A receives the sensing signal. When the sensing signal is transmitted by the first node and the first node is the terminal A, the process of communication sensing can be: the base station transmits the sensing signal, the terminal A receives the sensing signal or the terminal B transmits the sensing signal, and the terminal A receives the sensing signal.

[0047] It should be understood that the difference data is the difference between the sensing data and the reference data, and the difference is smaller than the value of the sensing data. Therefore, the resource overhead of the reported data can be reduced.

[0048] In some embodiments, the data can be quantized in the process of reporting the data by the node. That is, for a data, the actual information reported is the bit sequence corresponding to the quantization interval in which the data is located, rather than the data itself. On the one hand, the value of the reported data is smaller, which can improve the granularity of the quantization interval. At this time, the higher the quantization accuracy is, the smaller the quantization noise is. Therefore, compared with reporting the sensing data, reporting the difference data with a smaller value can improve the accuracy of the sensing result of the sensing object obtained by the sensing network element, and can improve the sensing accuracy of the communication sensing. On the other hand, the number of quantization bits can also be reduced, so that the bit sequence reported is shorter. In this way, the transmission resources required for communication sensing can be reduced.

[0049] For example, it is assumed that the number of quantization bits when reporting the sensing data is 2, the quantization interval includes [0, 1], [1, 2], [2, 3], [3, 4], the value of the sensing data to be reported is 0.5, and the difference data to be reported is 0.1. In the case where the number of quantization bits is unchanged and the granularity of the quantization interval is improved, the quantization interval when reporting the difference data can be [0, 0.2], [0.2, 0.3], [0.3, 0.4], [0.4, 0.5]. At this time, the quantization noise corresponding to the reported sensing data is 0.5, and the quantization noise corresponding to the reported difference data is 0.1. Therefore, reporting the difference data can reliably reduce the quantization noise and improve the accuracy of the communication sensing. It is assumed that in the case where the number of quantization bits is reduced to 1, the quantization interval can be [0, 0.3], [0.3, 0.5]. At this time, the quantization noise corresponding to the reported sensing data is 0.5, and the quantization noise corresponding to the reported difference data is 0.2, which can reliably reduce the quantization noise, and the length of the bit sequence to be reported changes from 2 to 1. In this way, the accuracy of the communication sensing is improved, and the transmission resources required for the communication sensing are also reduced.

[0050] In some embodiments, the reference data is determined by one of the following: pre-configuration, pre-definition, and determination based on a reference sensing signal received by the first node. The reference sensing signal and the sensing signal corresponding to the sensing data are transmitted by the same node.

[0051] Exemplarily, when the reference data is determined by pre-configuration, the reference data can be pre-configured for the first node.

[0052] Exemplarily, when the reference data is determined by pre-definition, the perception network element can send the reference data to the first node, and the first node receives the reference data.

[0053] Exemplarily, when the reference data is determined based on the reference perception signal received by the first node, the node sending the perception signal can send the reference perception signal, the first node receives the reference perception signal, and determines the perception data of the perception object corresponding to the reference perception signal. The first node determines the perception data of the perception object corresponding to the reference perception signal as the reference data.

[0054] In some embodiments, the first node can also determine historical perception data as the reference data. The historical perception data is the perception data determined by the first node based on the perception signal received before the latest received perception signal.

[0055] In some embodiments, the differential data is reported by one of the following reporting manners: periodic reporting, event reporting, and event-triggered periodic reporting.

[0056] Exemplarily, the first node can report the differential data once every 1 second.

[0057] Exemplarily, the first node can report the differential data when the value of the differential data meets the reporting condition.

[0058] Exemplarily, the first node can start to periodically report the differential data (such as reporting once every 1 second) when the value of the differential data meets the reporting condition.

[0059] In some embodiments, the differential data includes at least one of the following: a differential operation result of the perception signal, a differential operation result of the channel information corresponding to the perception signal, a differential operation result of intermediate perception data, and a differential operation result of the perception result corresponding to the perception object. The intermediate perception data is data generated in the process of determining the perception result based on the perception signal or the channel information.

[0060] In some embodiments, the perception signal includes at least one of the following: a time domain signal and a frequency domain signal.

[0061] In some embodiments, the perception signal received by the first node can be a time domain orthogonal frequency division multiplexing (OFDM) symbol.

[0062] The following will be explained in the case of the sensing signal being a time domain signal or the sensing signal being a frequency domain signal. The sensing signal being a time domain signal is scenario one, and the sensing signal being a frequency domain signal is scenario two.

[0063] Scenario one: the difference operation result of the sensing signal is a difference operation result of a time domain OFDM symbol.

[0064] Exemplarily, assuming that the time domain OFDM symbols received by the first node are y1,..., yN, and the time domain OFDM symbol serving as a reference is y0, at this time, the difference operation result of the sensing signal is y1-y0,..., yN-y0. N-1 , the time domain OFDM symbol serving as a reference is y0, at this time, the difference operation result of the sensing signal is y1-y0,..., yN-y0. N-1

[0065] Exemplarily, in the case of the time domain OFDM symbol being used to extract Doppler information, assuming that the time domain OFDM symbols are y0, y1,..., yN, at this time, the difference operation result of the sensing signal is y1-y0,..., yN-y0. N-1 N-1

[0066] It should be understood that, since in the case of the difference operation result of the time domain OFDM symbol being used to extract Doppler information, the Doppler domain loses the 0 frequency component, the information of the dynamic target will not be lost. Therefore, subtracting the first time domain OFDM symbol y0 from each time domain OFDM symbol, the difference operation result obtained can not contain the result 0 of y0-y0. Since the difference process can eliminate the energy of the static target, more quantization dynamic range can be reserved for the weak dynamic target, so that the quantization noise and the overhead of the report can be reduced.

[0067] Scenario two: the first node can first convert the time domain OFDM symbol into a frequency domain OFDM symbol, and determine the difference operation result of the frequency domain OFDM symbol as the difference operation result of the sensing signal. Alternatively, the first node can first determine the difference operation result of the time domain OFDM symbol, and then convert the difference operation result of the time domain OFDM symbol into the difference operation result of the frequency domain OFDM symbol.

[0068] Exemplarily, assuming that the time domain OFDM symbols received by the first node are y1,..., yN, and the frequency domain OFDM symbol serving as a reference is Y0, at this time, converting the time domain OFDM symbol into a frequency domain OFDM symbol can obtain Y1,..., YN, and the difference operation result of the sensing signal is Y1-Y0,..., YN-Y0. N-1 N- N-1

[0069] ​​​​​​Exemplarily, assuming that the time-domain OFDM symbols received by the first node are y1, y2,..., yN, and the time-domain OFDM symbol taken as the reference is y0, the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained. N-1 , the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained. N-1 , the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained. N-1 , the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained.

[0070] Exemplarily, in the case where the difference operation results of the frequency-domain OFDM symbols are used to extract Doppler information, assuming that the time-domain OFDM symbols y0, y1,..., yN are received by the first node, and the difference operation results of the frequency-domain OFDM symbols Y1-Y0, Y2-Y0,..., YN-Y0 can be obtained. N-1 , the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained. N-1 , the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained.

[0071] It should be understood that, since in the case where the difference operation results of the frequency-domain OFDM symbols are used to extract Doppler information, the 0 frequency component is lost in the Doppler domain, the information of the dynamic target will not be lost. Therefore, the difference operation results obtained by subtracting each frequency-domain OFDM symbol from the first frequency-domain OFDM symbol Y0 can not contain the result 0 of Y0-Y0. Since the difference operation process can eliminate the energy of the stationary target, more quantization dynamic range can be reserved for the weak dynamic target, so that the quantization noise and the overhead of the report can be reduced.

[0072] In some embodiments, the channel information corresponding to the sensing signal comprises at least one of: time-domain channel information, frequency-domain channel information.

[0073] The difference operation results of the channel information corresponding to the sensing signal will be explained below in the case where the channel information corresponding to the sensing signal is time-domain channel information or the channel information corresponding to the sensing signal is frequency-domain channel information. The case where the channel information corresponding to the sensing signal is time-domain channel information is scenario three, and the case where the channel information corresponding to the sensing signal is frequency-domain channel information is scenario four.

[0074] Scenario three: the difference operation results of the channel information corresponding to the sensing signal are the difference operation results of the time-domain channel information.

[0075] In some embodiments, the first node can estimate the time-domain channel information based on the time-domain OFDM symbols, and determine the difference operation results of the time-domain channel information.

[0076] Exemplarily, assuming that the time-domain OFDM symbols received by the first node are y1, y2,..., yN, and the time-domain OFDM symbol taken as the reference is y0, the difference operation results of the time-domain OFDM symbols y1-y0, y2-y0,..., yN-y0 can be obtained. N-1, the time-domain channel information as a reference is h0. At this time, the first node estimates the time-domain channel information based on the time-domain OFDM symbols as h1,..., h N-1 , the difference operation result of the time-domain channel information is h1-h0,..., h N-1 -h0.

[0077] Exemplarily, in the case that the difference operation result of the time-domain channel information is used to extract Doppler information, it is assumed that the time-domain OFDM symbols received by the first node are y0, y1,..., y N-1 . At this time, the time-domain channel information is h0, h1,..., h N-1 , the difference operation result of the time-domain channel information is h1-h0,..., h N-1 -h0.

[0078] It should be understood that, since in the case that the difference operation result of the time-domain channel information is used to extract Doppler information, the 0 frequency component is lost in the Doppler domain, the information of a dynamic target will not be lost. Therefore, the difference operation result obtained by subtracting the first time-domain channel information h0 from each time-domain channel information can not contain the result 0 of h0-h0. Since the difference operation process can eliminate the energy of a static target, more quantization dynamic range can be reserved for a weak dynamic target, so that the quantization noise and overhead of reporting can be reduced.

[0079] In some embodiments, the first node can convert the time-domain OFDM symbols into frequency-domain OFDM symbols; and estimate the frequency-domain channel information based on the frequency-domain OFDM symbols and the perception signal, and convert the frequency-domain channel information into time-domain channel information; and then, the difference operation result of the time-domain channel information can be determined.

[0080] In some embodiments, the time-domain channel information can be truncated based on an expected time delay or an expected distance range to obtain expected time-domain channel information. And the difference operation result of the expected time-domain channel information is determined as the difference operation result of the channel information corresponding to the perception signal.

[0081] Scenario four: the difference operation result of the channel information corresponding to the perception signal is the difference operation result of the frequency-domain channel information.

[0082] In some embodiments, the first node can convert the time-domain OFDM symbols into frequency-domain OFDM symbols; and estimate the frequency-domain channel information based on the frequency-domain OFDM symbols and the perception signal; and then determine the difference operation result of the frequency-domain channel information.

[0083] Exemplarily, it is assumed that the time-domain OFDM symbols received by the first node are y1,..., y N-1, the frequency domain channel information as the reference is H0. At this time, the frequency domain OFDM symbols are Y1,..., Y N-1 , the first node estimates the time domain channel information as H1,..., H N-1 , the difference operation result of the time domain channel information is H1-H0,..., H N-1 -H0.

[0084] In some embodiments, the first node can first determine the difference operation result of the time domain channel information, and then convert the difference operation result of the time domain channel information into the difference operation result of the frequency domain channel information.

[0085] In some embodiments, in the case that the difference operation result of the sensing signal or the channel information corresponding to the sensing signal is used to extract Doppler information, the time domain OFDM symbol received by the first node is a symbol within the coherent processing time.

[0086] It should be understood that the coherent processing time includes a plurality of time domain OFDM symbols, and coherent processing of these symbols can obtain Doppler information.

[0087] In some embodiments, the difference operation result of the intermediate sensing data includes at least one of the following: a difference operation result of a delay spread spectrum, a difference operation result of a Doppler spectrum, a difference operation result of a micro-Doppler spectrum, a difference operation result of an angle spectrum, a difference operation result of a signal strength spectrum, a difference operation result of a time delay related to a sensing object, a difference operation result of an angle related to a sensing object, a difference operation result of Doppler information related to a sensing object, a difference operation result of micro-Doppler information related to a sensing object, and a difference operation result of phase information related to a sensing object.

[0088] It should be understood that the difference operation result of the delay spread spectrum can be used to determine the time delay information related to the sensing object. The difference operation result of the Doppler spectrum can be used to determine the frequency shift information related to the sensing object, and further determine the motion information of the sensing object. The difference operation result of the micro-Doppler spectrum can be used to determine the micro-motion information of the sensing object. The difference operation result of the angle spectrum can be used to determine the incident angle, the exit angle, and other information of the sensing signal, and further determine the angle information related to the sensing object. The difference operation result of the signal strength spectrum can be used to determine the signal strength change information of the sensing signal, and further obtain the position information of the sensing object.

[0089] In some embodiments, the time delay related to the sensing object can be determined based on the delay spread spectrum, and the difference operation result of the time delay related to the sensing object can be obtained.

[0090] It should be understood that the difference operation result of the time delay information related to the sensing object can be used to determine the position information or the position change information of the sensing object.

[0091] In some embodiments, the Doppler information related to the sensing object can be determined based on the Doppler spectrum, and then the difference operation result of the Doppler information related to the sensing object can be obtained.

[0092] It should be understood that the difference operation result of the Doppler information related to the sensing object can be used to determine the motion information (such as the speed information, the vibration information) of the sensing object or the change information of the motion information.

[0093] In some embodiments, the micro-Doppler information related to the sensing object can be determined based on the micro-Doppler spectrum, and then the difference operation result of the micro-Doppler information related to the sensing object can be obtained.

[0094] It should be understood that the difference operation result of the micro-Doppler information related to the sensing object can be used to determine the slight motion information of the sensing object or the change information of the slight motion information.

[0095] In some embodiments, the difference operation result of the time delay information related to the sensing object can be obtained by measuring the time domain orthogonal frequency division multiplexing symbol in the sensing signal to obtain the time delay information of the sensing object, and determining the difference operation result of the time delay information related to the sensing object based on the time delay information of the sensing object and the reference data corresponding to the time delay information.

[0096] In some embodiments, the reference data corresponding to the time delay information can be determined in one of the following ways: pre-configuration, pre-definition by the sensing network element, and time delay information of a line-of-sight (LOS) path in the sensing signal.

[0097] In some embodiments, the difference operation result of the phase information related to the sensing object can be obtained by determining the phase information related to the sensing object based on the time domain orthogonal frequency division multiplexing symbol in the sensing signal, and determining the difference operation result of the phase information related to the sensing object based on the phase information related to the sensing object and the reference data corresponding to the phase information.

[0098] It should be understood that since the sensing object reflects the sensing signal, the phase of the sensing signal changes, and therefore, reporting the phase information related to the sensing object enables the sensing network element to reliably determine the position information of the sensing object.

[0099] In addition, the difference operation result of the phase information related to the sensing object enables the sensing network element to reliably determine the position change information or the distance information of the sensing object.

[0100] In some embodiments, the difference operation result of the perception result comprises at least one of a difference operation result of a radar cross section of the perceived object, a difference operation result of a position of the perceived object, a difference operation result of a speed of the perceived object, a difference operation result of a number of the perceived object, and a difference operation result of a distance between the perceived object and a reference point.

[0101] It should be understood that the radar cross section of the perceived object is used to indicate an area of the perceived object reflecting the perception signal; based on the radar cross section of the perceived object, the profile information of the perceived object can be reliably determined; and the difference operation result of the radar cross section of the perceived object can reliably determine the profile change information of the perceived object.

[0102] In some embodiments, the reference point can be a location of the first node or a pre-set other location.

[0103] In combination with the embodiment shown in FIG. 2, as shown in FIG. 3, the information reporting method further comprises S301.

[0104] S301, sending first information to the perception network element.

[0105] The first information is used to indicate the perception capability of the first node.

[0106] It should be understood that the first node can report the perception capability of the first node to the perception network element, so that the perception network element can determine the type of the perception data reported by the perception network element based on the perception capability of the first node.

[0107] In combination with the embodiment shown in FIG. 3, as shown in FIG. 4, the information reporting method further comprises S401.

[0108] S401, receiving configuration information sent by the perception network element.

[0109] The configuration information is determined based on the perception capability of the first node. The configuration information is used for the first node to perform communication perception.

[0110] In some embodiments, the configuration information is used to indicate or comprise at least one of a perception mode of the first node for communication perception, a perception role of the first node for communication perception, a data type of the perception data reported by the first node, a difference reporting manner of the first node, and corresponding reference data when the first node performs difference reporting.

[0111] In some embodiments, the perception capability of the first node comprises at least one of a perception mode supported by the first node, a processing capability of the first node, a perception role supported by the first node, and a perception accuracy supported by the first node.

[0112] In some embodiments, the sensing mode of the first node comprises at least one of: the first node transmitting the sensing signal and the first node receiving the sensing signal, the second node transmitting the sensing signal and the first node receiving the sensing signal.

[0113] It should be understood that the first node reports to the sensing network element the sensing mode that the first node can support, and the sensing network element can determine the sensing mode that the first node needs to adopt based on the demand (such as the scenario of communication sensing, whether there is other equipment that can cooperate with the first node to complete communication sensing). In this way, it can be ensured that the first node can reliably perform communication sensing, and the first node can adopt the sensing mode that best meets the demand, ensuring the effectiveness of communication sensing and improving user experience.

[0114] In some embodiments, the processing capability of the first node comprises one of: no capability of processing the sensing signal, capability of processing the sensing signal to obtain intermediate sensing data, and capability of processing the sensing signal to obtain a sensing result.

[0115] For example, when the processing capability reported by the first node is no capability of processing the sensing signal, the sensing network element can determine that the difference data reported by the first node is the difference operation result of the sensing signal. When the processing capability reported by the first node is the capability of processing the sensing signal to obtain intermediate sensing data, the sensing network element can determine that the difference data reported by the first node is the difference operation result of the intermediate sensing data. When the processing capability reported by the first node is the capability of processing the sensing signal to obtain a sensing result, the sensing network element can determine that the difference data reported by the first node is the difference operation result of the sensing result of the sensing object. In this way, it can be ensured that the first node can perform a reliable information reporting process.

[0116] In some embodiments, the sensing role comprises at least one of: a sensing signal transmitting end, a sensing signal receiving end, and a sensing management end.

[0117] It should be understood that when the sensing role of the first node is the sensing signal transmitting end, the first node can transmit the sensing signal.

[0118] In some embodiments, managing and controlling the signal transmitting end and the signal receiving end can comprise at least one of: a time of transmitting the sensing signal, a signal strength of transmitting the sensing signal, a direction of transmitting the sensing signal, a range of transmitting the sensing signal, and a type of processing result of the received sensing signal by the signal receiving end.

[0119] It can be understood that after the first node reports the sensing role supported by the first node, the sensing network element can determine the sensing role of the first node based on the demand. In this way, the available resources of the communication sensing can be reliably coordinated, the communication sensing effectiveness is guaranteed, and the resource utilization rate is improved.

[0120] For example, it is assumed that the first node supports the sensing management end, and at this time, the sensing network element can determine the sensing role of the first node as the sensing management end, so that the first node can manage the process of communication sensing. In this way, the sensing network element does not have to be responsible for the management of the communication sensing process, thereby saving the resources of the sensing network element.

[0121] In some embodiments, the sensing role of the first node can be multiple.

[0122] For example, it is assumed that the sensing role of the first node can be the sensing signal sending end, the sensing signal receiving end, and the sensing management end. In this way, the first node can autonomously control the control information of the transmission or reception of the sensing signal, and transmit or receive the sensing signal based on the control information.

[0123] In some embodiments, the sensing accuracy includes at least one of the following: distance accuracy, distance resolution accuracy, speed accuracy, speed resolution accuracy, angle accuracy, angle resolution accuracy, and time delay information accuracy.

[0124] It should be understood that the sensing accuracy supported by different first nodes can be different. The sensing accuracy supported by the first node is reported to the sensing network element, and the sensing network element can determine whether to call the first node to complete the communication sensing based on whether the sensing accuracy supported by the first node can meet the sensing demand. Or the sensing network element can determine the sensing accuracy required by the first node based on the sensing demand, and make the first node report information based on the required sensing accuracy.

[0125] In some embodiments, the first node can report second information to the sensing network element, and the second information is used to indicate whether the first node supports differential reporting (i.e., whether to report differential data).

[0126] In some embodiments, the configuration information sent by the sensing network element to the first node further includes whether the first node performs differential reporting.

[0127] In some embodiments, the information reporting method provided by the embodiments of the present disclosure can also be executed by the sensing network element 102 in the information reporting system shown in FIG. 1.
