[0052] The feedback methods, apparatus, devices, and storage media provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0054] Figure 2 This is a flowchart illustrating a feedback method provided in an embodiment of this disclosure. The method is executed by a signal measurement node, such as... Figure 2 As shown, the feedback method may include the following steps:

[0055] Step 201: Determine the configuration information corresponding to each of the M time points. This configuration information is used to configure the processing method corresponding to each time point, where M is a positive integer.

[0056] In one embodiment of this disclosure, the method can be applied to the AI ​​positioning process.

[0057] In one embodiment of this disclosure, the aforementioned "M time points" can be the time points corresponding to the signal processing results that the signal measurement node needs to feed back to the positioning device. In other words, the "M time points" can indicate that the signal measurement node needs to feed back the signal processing results at the M time points to the positioning device.

[0058] Optionally, in one embodiment of this disclosure, the above-mentioned processing method can be a processing method of the actual measured values ​​corresponding to each time point by the signal measurement node, and a signal processing result at each time point can be obtained after processing the actual measured values ​​corresponding to each time point based on the processing method corresponding to each time point. The actual measured values ​​corresponding to each time point can be: the measured values ​​obtained by measuring the reference signal to be measured at each time point, where the reference signal can be a positioning reference signal (PRS) or a sounding reference signal (SRS). Optionally, in one embodiment of this disclosure, the signal processing results at the above-mentioned M time points can be used to determine the positioning location of the device to be positioned to achieve positioning. The device to be positioned can be a signal measurement node, or it can be a device that transmits a reference signal.

[0059] Optionally, in one embodiment of this disclosure, the M time points may correspond to one configuration information, which can be used to configure the processing method corresponding to all the M time points. In another embodiment of this disclosure, the M time points may correspond to at least one configuration information, wherein each configuration information corresponds to at least one time point, and the configuration information can be used to configure the processing method corresponding to the corresponding time point.

[0060] Optionally, in one embodiment of this disclosure, the method for determining configuration information may include at least one of the following:

[0061] Receive configuration information sent by the location server;

[0062] Configuration information is determined based on the agreement.

[0063] Configuration information is determined based on predefined criteria;

[0064] Configuration information is determined based on pre-configuration.

[0065] Optionally, in one embodiment of this disclosure, the signal processing result described above can be the value obtained after quantizing the actual measured value; and in one embodiment of this disclosure, the configuration information described above can include:

[0066] At least one quantization interval corresponding to each time point;

[0067] The quantization results corresponding to each quantization interval.

[0068] Optionally, the quantization intervals corresponding to each time point and the quantization results corresponding to each quantization interval can define the processing method for the actual measured values ​​at each time point. Specifically, the processing method for the actual measured values ​​at each time point can be as follows: the quantization interval to which the actual measured value at a certain time point belongs in at least one quantization interval corresponding to that time point is determined as the target quantization interval, and the quantization result corresponding to the target quantization interval is determined as the signal processing result at that time point.

[0069] For example, Table 1 is a table showing the correspondence between quantization intervals and quantization results included in configuration information provided in an embodiment of this disclosure.

[0070] Table 1

[0071] Signal measurement results <X 000 X < Signal measurement result < X + Y 001 X + Y < Signal measurement result < X + 2Y 010 X + 2Y < Signal measurement result < X + 3Y 011 X + 3Y < Signal measurement result < X + 4Y 100 .... ....

[0072] It is understood that Table 1 merely illustrates one possible correspondence between quantization ranges and quantization results; other possible quantization correspondences may be used in practice. Furthermore, each element in Table 1 exists independently. These elements are listed in the same table as an example, but this does not mean that all elements in the table must exist simultaneously as shown in the table. The value of each element is independent of the values ​​of any other element in Table 1. Therefore, those skilled in the art will understand that the value of each element in Table 1 is an independent embodiment.

[0073] As shown in Table 1, if the correspondence between the quantization interval and the quantization result at a certain time point is as shown in Table 1, then when the actual measured value at that time point is greater than X+Y and less than X+2Y, the processing method corresponding to that time point can be determined as follows: 010 is determined as the signal processing result at that time point.

[0074] Optionally, in one embodiment of this disclosure, the configuration information corresponding to different time points may be the same, or the configuration information corresponding to different time points may be different. For example, the interval lengths of the quantization intervals corresponding to different time points may be the same or different, and the quantization results corresponding to the quantization intervals at different time points may be the same or different. Optionally, the interval lengths of different quantization intervals within at least one quantization interval corresponding to the same time point may also be the same or different.

[0075] Optionally, in one embodiment of this disclosure, when the configuration information corresponding to different time points is different, the interval length of the quantization interval corresponding to a time point within a specific time range can be smaller than the interval length of the quantization interval corresponding to a time point outside the specific time range. Optionally, the specific time range may include the arrival time of the first path of the reference signal under test arriving at the signal measurement node (i.e., the first path arrival time). The specific time range can be understood as: the time near the arrival time of the first path of the reference signal under test arriving at the signal measurement node.

[0076] Furthermore, the following explains why the quantization interval length corresponding to a time point within a specific time range should be less than the quantization interval length corresponding to a time point outside the specific time range.

[0077] Specifically, as described above, the process of determining the signal processing results at the M time points is as follows: The received reference signals at the M time points are measured to obtain signal measurement results; then, these M time point signal measurement results are quantized to obtain the signal processing results at the M time points. These M time point signal processing results are primarily used to subsequently determine the location of the device being located. It should be understood that, for the signal measurement node, noise signals may exist before and after receiving the reference signal. Furthermore, in the subsequent positioning process, accurate positioning is mainly achieved based on the signal processing results corresponding to the reference signal (i.e., the valid signal). Signal processing results corresponding to noise signals may not achieve accurate positioning. Therefore, it is necessary to ensure that the signal processing results corresponding to the reference signal are more accurate; for example, it should be ensured that the signal processing results corresponding to the reference signal are closer to the signal measurement results before quantization, thereby achieving accurate positioning.

[0078] Based on this, this disclosure includes the arrival time of the first path of the reference signal to be measured at the signal measurement node within a specific time range, thus including the reception time of the reference signal by the signal measurement node within the specific time range. Therefore, time points within the specific time range can be approximated as the time points when the signal measurement node receives the reference signal, and time points outside the specific time range can be approximated as the time points when the signal measurement node does not receive the reference signal (e.g., the time points when the signal measurement node receives noise signals). Simultaneously, the quantization interval length corresponding to time points within the specific time range is smaller than the quantization interval length corresponding to time points outside the specific time range. That is, the quantization granularity of the processing method corresponding to time points within the specific time range is smaller, while the quantization granularity of the processing method corresponding to time points outside the specific time range is larger. This ensures the quantization accuracy of the signal measurement results at time points within the specific time range, making the signal processing results obtained after quantization at time points within the specific time range closer to the signal measurement results before quantization. In other words, it ensures that the signal processing results corresponding to the reference signal are more accurate, thereby ensuring that precise positioning can be achieved subsequently based on the signal processing results at M time points. Meanwhile, by making the quantization granularity of signal measurement results located outside a specific range larger, the quantization complexity can be reduced and the quantization efficiency improved.

[0079] Step 202: Measure the reference signal to be measured to obtain the actual measured value.

[0080] Step 203: Based on the configuration information, process the actual measurement values ​​at M time points to obtain the signal processing results at M time points.

[0081] Optionally, in one embodiment of this disclosure, the aforementioned "quantizing the actual measured values ​​at M time points based on configuration information to obtain signal processing results at M time points" may include: determining the target quantization interval to which the actual measured value at each time point belongs in at least one quantization interval corresponding to each time point; and determining the quantization result corresponding to the target quantization interval as the signal processing result at each time point. For details regarding this part, please refer to the detailed description in Table 1 of step 201 above.

[0082] Step 204: Feed back the signal processing results at M time points to the positioning server.

[0083] Optionally, in one embodiment of this disclosure, signal processing results at M time points are fed back to the positioning server so that the positioning server can determine the location of the device being positioned based on the signal processing results at the M time points, thereby achieving precise positioning. The device being positioned can be the aforementioned signal measurement node, or it can be a device that transmits reference signals.

[0084] In summary, in the feedback method provided by this disclosure, the signal measurement node determines the configuration information corresponding to each of the M time points. This configuration information is used to configure the processing method corresponding to each time point, where M is a positive integer. Furthermore, the signal measurement node measures the reference signal to be measured to obtain the actual measured value, and processes the actual measured values ​​at the M time points based on the configuration information to obtain the signal processing results at the M time points; then, it feeds back the signal processing results at the M time points to the positioning server. Therefore, when the signal measurement node needs to feed back signal processing results at multiple time points, the method of this disclosure can determine the signal processing results at each time point, thereby achieving successful feedback of the signal processing results and ensuring the stable execution of the positioning process.

[0085] Figure 3 This is a flowchart illustrating a feedback method provided in an embodiment of this disclosure. The method is executed by a signal measurement node, such as... Figure 3 As shown, the feedback method may include the following steps:

[0086] Step 301: Measure the reference signal to be measured to obtain the actual measured value.

[0087] Step 302: Determine the reference value corresponding to each of the M time points.

[0088] Optionally, in one embodiment of this disclosure, each time point corresponds to a reference value, and at least two time points correspond to the same reference value.

[0089] Optionally, in one embodiment of this disclosure, the method for determining the reference value corresponding to each time point may include: the signal measurement node autonomously determining and / or determining, based on the transmission from the positioning server, which time points correspond to the same reference value; the signal measurement node assigning reference values ​​to the time points that correspond to the same reference value.

[0090] For example, assuming M is 3, if the signal measurement node autonomously determines that the first and second time points correspond to the same reference value, then the signal measurement node can assign the same reference value to the first and second time points, while assigning a different reference value to the third time point than to the first and second time points.

[0091] Optionally, in another embodiment of this disclosure, the method for determining the reference value corresponding to each time point may include: determining the reference value corresponding to each time point based on the transmission of the positioning server.

[0092] Step 303: Determine the offset of the actual measured value at each time point relative to the corresponding reference value at each time point.

[0093] For example, suppose the reference value at a certain time point is A, and the actual measured value at that time point is B. Then the offset value at that time point is either BA or AB.

[0094] Step 304: Determine the configuration information corresponding to each time point. The configuration information is used to configure the processing method corresponding to each time point, where M is a positive integer. The configuration information includes at least one of the following: at least one first quantization interval corresponding to the reference value corresponding to each time point, the quantization result corresponding to each first quantization interval, at least one second quantization interval corresponding to the offset value corresponding to each time point, and the quantization result corresponding to each second quantization interval.

[0095] Optionally, in one embodiment of this disclosure, the length of the first quantization interval corresponding to the same time point may be the same as or different from the length of the second quantization interval; the length of the first quantization interval corresponding to the reference values ​​at different time points may be the same as or different; and the length of the second quantization interval corresponding to the offset values ​​at different time points may be the same as or different.

[0096] For details regarding the roles of the first quantization interval and the second quantization interval, as well as the roles of the quantization results corresponding to the first quantization interval and the second quantization interval, please refer to the relevant introduction in Table 1 above.

[0097] Step 305: Based on the configuration information, quantize the reference value and offset value corresponding to the time point to obtain the signal processing result at the time point.

[0098] Optionally, in one embodiment of this disclosure, the aforementioned "quantization of reference values ​​and offset values ​​corresponding to time points based on configuration information" may include:

[0099] Step a: Quantize the reference value corresponding to the time point based on the first quantization interval and the quantization result corresponding to the first quantization interval; Optionally, the target quantization interval to which the reference value corresponding to each time point belongs in at least one first quantization interval corresponding to the reference value at each time point is determined; The quantization result corresponding to the target quantization interval is determined as the quantized result of the reference value corresponding to each time point.

[0100] Step b: Quantize the offset value corresponding to the time point based on the second quantization interval and the quantization result corresponding to the second quantization interval; Optionally, the target quantization interval to which the offset value corresponding to each time point belongs in at least one second quantization interval corresponding to the offset value at each time point; The quantization result corresponding to the target quantization interval is determined as the quantized result of the offset value corresponding to each time point;

[0101] Step c: Determine the quantized results of the reference values ​​corresponding to each time point and / or the quantized results of the offset values ​​corresponding to each time point as the processing results at each time point.

[0102] Step 306: Feed back the signal processing results at M time points to the positioning server.

[0103] Optionally, in one embodiment of this disclosure, signal processing results at M time points are fed back to the positioning server so that the positioning server can determine the location of the device being positioned based on the signal processing results at the M time points, thereby achieving precise positioning. The device being positioned can be the aforementioned signal measurement node, or it can be a device that transmits reference signals.

[0104] Optionally, in one embodiment of this disclosure, when the signal measurement node autonomously determines which time points correspond to the same reference value in step 302 above, the signal measurement node can also send indication information to the positioning server, which can indicate which time points correspond to the same reference value.

[0105] Optionally, in another embodiment of this disclosure, when the signal measurement node determines the reference value corresponding to each time point based on the transmission of the positioning server in step 302 above, the signal processing result fed back by the signal measurement node to the positioning server in step 306 may only include the quantized result of the offset value corresponding to each time point.

[0106] In summary, in the feedback method provided by this disclosure, the signal measurement node determines the configuration information corresponding to each of the M time points. This configuration information is used to configure the processing method corresponding to each time point, where M is a positive integer. Furthermore, the signal measurement node measures the reference signal to be measured to obtain the actual measured value, and processes the actual measured values ​​at the M time points based on the configuration information to obtain the signal processing results at the M time points; then, it feeds back the signal processing results at the M time points to the positioning server. Therefore, when the signal measurement node needs to feed back signal processing results at multiple time points, the method of this disclosure can determine the signal processing results at each time point, thereby achieving successful feedback of the signal processing results and ensuring the stable execution of the positioning process.

[0107] Figure 4 This is a flowchart illustrating a feedback method provided in an embodiment of this disclosure. The method is executed by a signal measurement node, such as... Figure 4 As shown, the feedback method may include the following steps:

[0108] Step 401: In response to the signal measurement node being a terminal device, determine the configuration information corresponding to each base station participating in the positioning.

[0109] Optionally, in one embodiment of this disclosure, the positioning process (such as an AI positioning process) typically involves a terminal device and multiple base stations. The device being located can be a terminal device or any of the multiple base stations. The signal measurement node can be a terminal device, or it can be any of the base stations. Optionally, when the signal measurement node is a terminal device, each base station can send a reference signal (e.g., a PRS) to the terminal device, so that the terminal device can measure and process the reference signals sent by each base station.

[0110] Optionally, in one embodiment of this disclosure, when the signal measurement node is a terminal device, the terminal device can determine the configuration information corresponding to each base station. The configuration information is used to configure the processing method corresponding to the actual measurement value of the reference signal sent by the base station at each of the M time points corresponding to the base station. Then, the terminal device can subsequently process the actual measurement value of the reference signal sent by each base station at the M time points based on the configuration information corresponding to each base station.

[0111] Optionally, in one embodiment of this disclosure, a base station may correspond to a configuration information, which can be used to configure the processing method corresponding to all time points among the M time points corresponding to the base station.

[0112] For example, assuming the signal measurement node is a terminal device, and the base stations participating in the positioning are base station #1, base station #2, and base station #3, the terminal device can determine the configuration information #1 corresponding to base station #1, the configuration information #2 corresponding to base station #2, and the configuration information #3 corresponding to base station #3. Configuration information #1 is used to configure the processing method corresponding to the actual measured values ​​at each of the M time points corresponding to the reference signal sent by base station #1. Configuration information #2 is used to configure the processing method corresponding to the actual measured values ​​at each of the M time points corresponding to the reference signal sent by base station #2. Configuration information #3 is used to configure the processing method corresponding to the actual measured values ​​at each of the M time points corresponding to the reference signal sent by base station #3.

[0113] Optionally, in another embodiment of this disclosure, a base station may correspond to at least one configuration information, and each configuration information may correspond to at least one time point. The configuration information may be used to configure the processing method corresponding to the corresponding time point.

[0114] For example, assuming the signal measurement node is a terminal device, the base stations participating in the positioning are base station #1, and the M time points corresponding to base station #1 are: time point #1, time point #2, time point #3, ..., time point #M. Then, this base station can have configuration information #1, configuration information #2, configuration information #3, ..., configuration information #M.

[0158] (1) A positioning measurement result feedback method, applied to a positioning signal measurement node, wherein the measurement feedback result includes information from M time sampling points, characterized in that the information at each time sampling point is quantized.

[0159] For example, to provide feedback on the channel impulse response, it is necessary to feed back the real and imaginary parts of the measured signal at multiple time sampling points; similarly, to provide feedback on the power distribution, it is necessary to feed back the power of the measured signal at multiple time sampling points.

[0160] (2) Based on (1), the quantization granularity is the same at each time sampling point.

[0164] (6) Based on (5), receive a configuration message from the positioning server, the configuration message including the quantization granularity corresponding to the time sampling point.

[0165] Specifically, the positioning server can estimate the arrival time of the positioning reference signal to the measurement node along the first path. For time sampling points near the estimated time, the corresponding quantization granularity is smaller, while for time sampling points outside the first path arrival time range, the corresponding quantization granularity can be larger.

[0169] (10) Based on (8), receive the configuration information of the positioning server, and determine the quantization granularity based on the configuration information.

[0170] (11) Based on (7), the quantization granularity corresponding to the N base stations is different.

[0171] (12) Based on (11), receive a configuration message from the positioning server, the configuration message including the independent quantization granularity for each base station.

[0172] (13) Based on (1), the information feedback at the sampling point includes reference value and offset information. The information at the reference point can be determined based on the reference value and offset value. The reference value is for at least two time sampling points, and the offset value is for one time sampling point.

[0173] (14) Based on (13), the reference value and the offset value are quantized.

[0174] (15) Based on (14), the quantization granularity of the reference value and the offset value can be different, and the quantization granularity can be determined based on pre-configuration or configuration information.

[0175] (16) Based on (15), the reference value may be different for different time sampling points of the same base station. The quantization granularity may be determined based on pre-configuration or configuration information.

[0176] (17) Based on (16), the reference value may differ for different base stations. The quantization granularity may be determined based on pre-configuration or configuration information.
