The UE supports ranging and/or sidelink positioning. The UE may serve as a target UE for ranging and/or sidelink positioning.

In some examples, the measurement values of ranging and/or sidelink positioning of the UE are used to determine the relative position of one of the UE and the reference device relative to the other.

In some examples, the measurement value of the UE may be a measurement value between the UE and a reference device; it may also be a measurement value between the UE and an auxiliary device.

In some examples, the measurement values of the UE include distance measurements and/or azimuth angle measurements.

In some examples, the measurement request is used to request the UE to perform ranging and/or measurement reporting of sidelink positioning.

In some examples, the measurement request may include measurement configuration information and/or reporting configuration information.

After the UE performs ranging and/or sidelink measurement according to the measurement request to obtain the measurement value, the measurement report value corresponding to the measurement value may be determined based on the corresponding relationship.

In some examples, the correspondence may be one or more sets; different sets of correspondence may be related to different reporting granularity factors, which can meet the mapping requirements of different long and short ranging ranges and/or different ranging accuracies.

Embodiments of the present disclosure propose a measurement reporting method. The UE receives the measurement request sent by the network side device and reports the measurement report value to the network side device. Compared with directly reporting the ranging and/or sidelink positioning of the UE, Measurement values, by reporting measurement report values corresponding to the measurement values, can reduce the signaling overhead caused by reporting measurement results and reduce waste of network resources.

In one embodiment, the corresponding relationship is related to reporting granularity.

Here, the reporting granularity refers to the smallest unit of the reported measurement value.

The reporting granularity of distance measurement values refers to the smallest unit of reported distance measurement values.

For example, the minimum unit of the reported distance measurement can be 100 centimeters, 1 meter, or 2 meters, etc.

The reporting granularity of the azimuth angle measurement value is the smallest unit of the reported azimuth angle measurement value.

For example, the minimum unit of the reported azimuth angle measurement value can be 10 degrees, 20 degrees, or 30 degrees, etc.

The reporting granularity can reflect the reporting accuracy of measurement values of ranging and/or sidelink positioning. The larger the reporting granularity, the lower the reporting accuracy. On the contrary, the smaller the reporting granularity, the higher the reporting accuracy.

In some embodiments, the reporting granularity is determined according to a protocol agreement or a reporting granularity factor configured by the network side device.

Here, the reporting granularity factor refers to a parameter that can affect the reporting granularity.

Different reporting granularity factors correspond to different reporting granularities.

In some examples, the reporting granularity factor is positively related to the reporting granularity. That is, the larger the reporting granularity factor is, the greater the reporting granularity is; the smaller the reporting granularity factor is, the smaller the reporting granularity is.

In some examples, the relationship between the reporting granularity and the reporting granularity factor may be: M=2 ^k , where M represents the reporting granularity, k represents the reporting granularity factor, and the value of k is an integer. .

In one embodiment, the measurement report value has a corresponding relationship with the measurement value of the UE, which may include:

When the measurement value of the UE is greater than or equal to the first threshold and less than the second threshold, the measurement report value is the first value; wherein the difference between the second threshold and the first threshold is Degree related.

In some examples, the first threshold and the second threshold may be determined based on the reporting granularity and reporting range.

In some examples, the reporting scope is a reporting scope agreed upon by a protocol or configured by a network.

In some examples, the reporting scope can be divided into multiple sub-ranges based on reporting granularity. The difference between the maximum and minimum values of different subranges corresponds to different measurement report values.

In one embodiment, the measurement report value corresponding to the measurement value of the UE may be an index (distance index) value. For example, the index value is an integer. Since the measurement report value is an index value, the number of bits of the measurement report value is significantly smaller than the total number of bits of the UE's measurement value. Therefore, the signaling overhead caused by reporting the measurement results can be further reduced and the waste of network resources can be reduced.

In one embodiment, the measured values include at least one of the following:

The ranging measurement value of the UE includes: a distance measurement value and/or an azimuth measurement value between the UE and a reference device;

The measurement value of the sidelink positioning of the UE includes: the distance measurement value between the UE and the reference device, and/or the azimuth angle measurement value.

In some examples, the reference device may include a reference UE and/or a base station used as a reference point.

In some examples, the distance measurement value may be obtained based on the transmission time of the ranging signal and/or the positioning reference signals (PRS) of the sidelink between the UE and the reference device multiplied by the speed of light.

In some examples, the azimuth angle may be an azimuth angle of arrival (AOA) or an azimuth angle of departure (Azimuth angle of departure, AOD).

In some examples, the reporting granularity factors include:

The first reporting granularity factor is used to determine the reporting granularity of the distance measurement value of the UE; the reporting granularity of the distance measurement value is used to determine the distance measurement value and the distance measurement report value based on the distance reporting range.

and / or,

Second correspondence between reported values of angle measurements.

In some examples, the distance reporting range and/or the azimuth angle reporting range may be determined according to a protocol agreement or reporting configuration information sent by the network side device.

In some examples, the determining process of the first correspondence may include:

Determine the reporting granularity of distance measurement values based on the first reporting granularity factor, and determine multiple distance ranges based on the reporting granularity of distance measurement values and the distance reporting range;

Correspondences between multiple distance report values and multiple distance ranges are determined to obtain the first correspondence.

In some examples, there is a one-to-one correspondence between the plurality of distance report values and the plurality of distance ranges.

In some examples, the distance measurement report value corresponding to the distance measurement value may be a distance index. The value of the distance index is an integer.

In some examples, the relationship between the reporting granularity of the distance measurement value and the first reporting granularity factor may be: M1 = 2 ^k1 , where M1 represents the reporting granularity of the distance measurement value, and k1 represents the first reporting granularity. Granularity factor, the value of k1 is an integer.

For example, assuming that the reporting granularity of the distance measurement value determined according to the first reporting granularity factor is M1, the minimum reporting distance of the distance reporting range is x1, and the maximum reporting distance is y1, then the minimum reporting distance and the maximum reporting distance can be n first distance ranges are determined, a second distance range whose upper limit is the minimum reported distance, and a third distance range whose lower limit is the maximum reported distance are determined. Among them, when (y1-x1)/M1 is an integer, m is equal to (y1-x1)/M1; when (y1-x1)/M1 is not an integer, m is obtained by rounding up (y1-x1)/M1 Integer value.

In some examples, multiple distance measurement report values corresponding to the second distance range, the m first distance ranges, and the third distance range are incremented in sequence.

For example, the distance measurement report value corresponding to the second distance range is distance_0, the distance measurement report values corresponding to m first distance ranges are distance_1, distance_2,...distance_m, and the distance measurement report value corresponding to the third distance range is distance_m. +1.

In some examples, if the first reporting granularity factor is updated, the reporting granularity of the distance measurement value is updated according to the updated first reporting granularity factor. In this example, the maximum reporting distance and/or the minimum reporting distance of the distance reporting range may be updated at the same time or remain unchanged.

In some examples, the process of determining the second corresponding relationship may include:

Determine the reporting granularity of the azimuth angle measurement value according to the second reporting granularity factor, and determine multiple azimuth angle ranges based on the reporting granularity of the azimuth angle measurement value and the azimuth angle reporting range;

Correspondences between multiple azimuth angle report values and multiple azimuth angle ranges are determined to obtain the second correspondence relationship.

In some examples, there is a one-to-one correspondence between the azimuth measurement values and the azimuth measurement report values.

In some examples, the azimuth angle measurement report value corresponding to the azimuth angle measurement value may be a direction index. The value of the orientation index is an integer.

In some examples, the relationship between the reporting granularity of the azimuth angle measurement value and the second reporting granularity factor may be: M2 = 2 ^k2 , where M2 represents the reporting granularity of the azimuth angle measurement value, and k2 represents the third 2. Report the granularity factor, and the value of k2 is an integer.

For example, assuming that the reporting granularity of the azimuth angle measurement value determined according to the second reporting granularity factor is M2, the minimum reported azimuth angle of the azimuth angle reporting range is x2, and the maximum reported azimuth angle is y2, then the minimum reported azimuth angle can be n first azimuth angle ranges are determined between the angle and the maximum reported azimuth angle, and a second azimuth angle range with an upper limit value being the minimum reported azimuth angle and a third azimuth angle range with a lower limit value being the maximum reported azimuth angle are determined. Among them, when (y2-x2)/M2 is an integer, n is equal to (y2-x2)/M2; when (y2-x2)/M2 is not an integer, n is obtained by rounding up (y2-x2)/M2 Integer value.

In some examples, a plurality of azimuth angle measurement report values corresponding to the second azimuth angle range, the n first azimuth angle ranges, and the third azimuth angle range are sequentially increased.

For example, the azimuth measurement report value corresponding to the second azimuth range is distance_0, the distance measurement report values corresponding to n first azimuth ranges are direction_1, direction_2,...direction_n, and the azimuth angle corresponding to the third azimuth range is The measurement report value is distance_n+1.

In some examples, if the second reporting granularity factor is updated, the reporting granularity of the azimuth measurement value is updated according to the updated second reporting granularity factor. In this example, the maximum azimuth distance and/or the minimum reported azimuth of the azimuth reporting range may be updated simultaneously or remain unchanged.

Therefore, the signaling overhead caused by reporting the measurement results can be further reduced and the waste of network resources can be reduced.

In one embodiment, the measured values include at least one of the following:

The measurement value of the ranging of the UE includes: the distance measurement value between the UE and the reference device, and/or the azimuth angle measurement value;

Granularity factor, the value of k1 is an integer.

For example, assuming that the reporting granularity of the distance measurement value determined according to the first reporting granularity factor is M1, the minimum reporting distance is x1, and the maximum reporting distance is y1, then n can be determined between the minimum reporting distance and the maximum reporting distance. a first distance range, and determine a second distance range whose upper limit is the minimum reported distance and a third distance range whose lower limit is the maximum reported distance. Among them, when (y1-x1)/M1 is an integer, m is equal to (y1-x1)/M1; when (y1-x1)/M1 is not an integer, m is obtained by rounding up (y1-x1)/M1 Integer value.

In some examples, multiple distance measurement report values corresponding to the second distance range, m first distance ranges, and third distance ranges are sequentially increased.

For example, the distance measurement report value corresponding to the second distance range is distance_0, the distance measurement report values corresponding to m first distance ranges are distance_1, distance_2,...distance_m, and the distance measurement report value corresponding to the third distance range is distance_m. +1.

In some examples, if the first reporting granularity factor is updated, the reporting granularity of the distance measurement value is updated according to the updated first reporting granularity factor. In this example, the maximum reporting distance and/or the minimum reporting distance of the distance reporting range may be updated at the same time or remain unchanged.

In some examples, the determining process of the second correspondence relationship may include:

Determine the reporting granularity of the azimuth angle measurement value according to the second reporting granularity factor, and determine multiple azimuth angle ranges based on the reporting granularity of the azimuth angle measurement value and the azimuth angle reporting range;

Determine the correspondence between multiple azimuth report values and multiple azimuth ranges to obtain the second correspondence.

In some examples, there is a one-to-one correspondence between the azimuth angle measurement value and the azimuth angle measurement report value.

In some examples, the azimuth angle measurement report value corresponding to the azimuth angle measurement value may be a direction index. The value of the orientation index is an integer.

In some examples, the relationship between the reporting granularity of the azimuth angle measurement value and the second reporting granularity factor may be: M2=2 ^k2 , where M2 represents the reporting granularity of the azimuth angle measurement value, k2 represents the second reporting granularity factor, and the value of k2 is an integer.

For example, assuming that the reporting granularity of the azimuth angle measurement value determined according to the second reporting granularity factor is M2, the minimum reported azimuth angle of the azimuth angle reporting range is x2, and the maximum reported azimuth angle is y2, then the minimum reported azimuth angle can be n first azimuth angle ranges are determined between the angle and the maximum reported azimuth angle, and a second azimuth angle range with an upper limit value being the minimum reported azimuth angle and a third azimuth angle range with a lower limit value being the maximum reported azimuth angle are determined. Among them, when (y2-x2)/M2 is an integer, n is equal to (y2-x2)/M2; when (y2-x2)/M2 is not an integer, n is obtained by rounding up (y2-x2)/M2 Integer value.

In some examples, the plurality of azimuth angle measurement report values corresponding to the second azimuth angle range, the n first azimuth angle ranges, and the third azimuth angle range are sequentially increased.

For example, the azimuth measurement report value corresponding to the second azimuth range is distance_0, the distance measurement report values corresponding to n first azimuth ranges are direction_1, direction_2,...direction_n, and the azimuth angle corresponding to the third azimuth range is The measurement report value is distance_n+1.

In some examples, if the second reporting granularity factor is updated, the reporting granularity of the azimuth angle measurement value is updated according to the updated second reporting granularity factor. In this example, the maximum azimuth distance and/or the minimum reported azimuth angle of the azimuth angle reporting range may be updated at the same time or remain unchanged.

In order to further explain any embodiments of the present disclosure, several specific examples are provided below.

Embodiments of the present disclosure provide an information processing method, which may include the steps:

S1: The network side device configures ranging (Ranging) measurement and reports configuration information to the UE through the first message.

The network side device may be a location server.

Here, the first message may be an LPP message or an NRPP message. For example, the first message may be: NR-DL-TDOA-RequestLocationInformation (NR downlink arrival time difference - positioning request information) or NR-DL-AoD-RequestLocationInformation (NR downlink departure position) in the information element (Information Element, IE). angular-positioning request information).

The reporting configuration information at least includes: a reporting granularity factor k1 (for example, the first reporting granularity factor in the above embodiment) and a reporting granularity factor k2 (for example, the distance and/or azimuth angle reported by ranging measurements). , the second reporting granularity factor in the above embodiment), the value ranges of k1 and k2 can be (k1_min, k1_max) and (k2_min, k2_max) respectively, where k1_min, k1_max and k2_min, k2_max are all integers;

S2: The UE reports the measurement results of the distance and orientation values relative to the reference point to the location server through the second message.

The second message may be an LPP message or an NRPP message. For example, the second message may be: NR-DL-TDOA-SignalMeasurementInformation (NR downlink arrival time difference-signal measurement information) in IE or IE NR-DL-AoD-SignalMeasurementInformation (NR downlink departure azimuth angle-signal measurement information) .

When reporting the measurement result, the UE maps the measurement result and reports a measurement report value mapped to the measurement result. The mapping method for reporting measurement results is as follows:

Assume that the reported range of distance measurement values is [x1, y1], then the reported granularity size is 2 ^k1 , and the unit can be meters or centimeters. For example, if the value of k1 is -1, the reported distance measurement value is mapped as follows:

It can be understood that each element in the above table exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is not dependent on the value of any other element in the table. Therefore, those skilled in the art can understand that the value of each element in the table is an independent embodiment.

It can be understood that, for distance reporting, the value of k1 can be set according to actual needs. In some examples, the value of k1 can be a positive integer. For example, if k1 is 5 and the unit is centimeters, then the reported granularity is 32 centimeters. In other examples, the value of k1 can be a negative integer. For example, if k1 is -2 and the unit is meters, the reported granularity is 0.25m; for another example, if k1 is -3, the reported granularity is 0.125m.

Assume that the reporting range of the azimuth measurement value is [x2, y2], then the reporting granularity is 2 ^k2 , and the unit can be degrees (degree) or radians (rad).

For example, if the k2 value is 1, the reported mapping of the azimuth measurement value is as follows:

It can be understood that each element in the above table exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is not dependent on the value of any other element in the table. Therefore, those skilled in the art can understand that the value of each element in the table is an independent embodiment.

It can be understood that, for the reporting of the azimuth angle, the value of k2 can be set according to actual needs. In some examples, k1 can take a value of a positive integer. For example, k2 can take a value of 0, 1, and 2, and the unit is a degree, and the reporting granularity is 1 degree, 2 degrees, and 4 degrees respectively.

The embodiment of the present disclosure provides a measurement reporting method, which can reduce the accuracy error of ranging and/or sidelink positioning measurement by configuring a reporting granularity factor and mapping the measurement results of distance and/or azimuth measurement in ranging measurement.
