[0049] Ranging is used to determine the distance between two terminals and / or the direction and / or the position of one UE relative to another UE.

[0050] Sidelink (SL) is a new link type introduced to support direct communication between V2X devices. Sidelink positioning uses the PC5 interface to locate terminals to obtain absolute position, relative position or ranging information.

[0051] Target UE: In the service based on ranging and / or sidelink positioning, the UE whose distance, direction and / or position are measured relative to the reference plane, reference direction and / or position of the reference UE.

[0052] Reference device: A device that determines the reference plane and reference direction in the service based on ranging and / or sidelink positioning.

[0053] Assistant device: A device that provides assistance information for ranging and / or sidelink positioning when direct ranging and / or sidelink positioning between the reference UE and the target UE is not supported; wherein the assistant device can include a UE or a base station different from the target UE and the reference UE.

[0054] Figure 2 FIG. 1 is a flowchart of a measurement reporting method according to an example embodiment. The measurement reporting method is performed by a user equipment (UE), as shown in FIG. 1, the measurement reporting method can include the steps of: Figure 2

[0055] 101: receiving a measurement request sent by a network side device;

[0056] 102: reporting a measurement report value to the network side device; the measurement report value has a corresponding relationship with a measurement value of the UE, wherein the measurement value of the UE includes a measurement value of ranging of the UE and / or a measurement value of sidelink positioning of the UE.

[0057] The UE can include but is not limited to a mobile phone, a tablet computer, a laptop computer, a personal digital assistant (PDA), a wearable device, a vehicle device, an unmanned aerial vehicle, a roadside device, an Internet of Things (IoT) device, and / or a Narrowband IoT (NB-IOT) device, etc.

[0058] In some examples, the network side device can be a core network device, for example, the network side device can be a location management function (LMF) or a gateway mobile location center (GMLC) or an enhanced serving mobile location center (E-SMLC), etc.​

[0059] In some examples, the network-side device can be a location server independent of the access network device and the core network device. The location server can interact with the UE through a service interface provided by a gateway mobile location center (GMLC).

[0060] It can be understood that the location management function (LMF), the gateway mobile location center (GMLC), the location server and the like are only examples, and in other embodiments, other location server functions and / or base station functions can be replaced, respectively.

[0061] The UE supports ranging and / or sidelink positioning. The UE can be a target UE for ranging and / or sidelink positioning.

[0062] In some examples, the measurement value of the UE for ranging and / or sidelink positioning is used to determine the relative position of one of the UE and the reference device relative to the other.

[0063] In some examples, the measurement value of the UE can be a measurement value between the UE and the reference device, or a measurement value between the UE and the assistance device.

[0064] In some examples, the measurement value of the UE includes a distance measurement value and / or an azimuth angle measurement value.

[0065] In some examples, in step 101, the UE can receive the measurement request sent by the network-side device through a LTE positioning protocol (LPP) message or a NR positioning protocol (NRPP) message.

[0066] In some examples, the measurement request is used to request the UE to perform measurement reporting of ranging and / or sidelink positioning.

[0067] In some examples, the measurement request can include measurement configuration information and / or reporting configuration information.

[0068] The measurement configuration information is used to instruct the UE to perform ranging and / or sidelink positioning measurement.

[0069] The reporting configuration information is used to determine the correspondence between the measurement value of the UE and the measurement report value.

[0070] Exemplarily, the measurement request message can be, for example, NR-DL-TDOA-RequestLocationInformation (NR downlink time difference of arrival-RequestLocationInformation) or NR-DL-AoD-RequestLocationInformation (NR downlink angle of departure-RequestLocationInformation) in an information element (IE).

[0071] In some examples, in step 102, the UE can report the measurement report value through an LPP message or an NRPP message.

[0072] For example, the measurement report value can be carried in NR-DL-TDOA-SignalMeasurementInformation (NR downlink time difference of arrival-SignalMeasurementInformation) or NR-DL-AoD-SignalMeasurementInformation (NR downlink angle of departure-SignalMeasurementInformation) in an IE.

[0073] In some examples, the correspondence between the measurement value of the UE and the measurement report value can be a correspondence configured by a protocol or a network side device.

[0074] In another example, the correspondence between the measurement value of the UE and the measurement report value can be determined according to measurement report information configured by a protocol or a network side device.

[0075] After the UE performs ranging and / or sidelink measurement to obtain a measurement value according to the measurement request, the measurement report value corresponding to the measurement value can be determined according to the correspondence.

[0076] In some examples, the correspondence can be one or more sets; different sets of the correspondence can be related to different reporting granularity factors, and can meet the mapping requirements of different ranging ranges and / or different ranging accuracies.

[0077] Embodiments of the present disclosure propose a measurement reporting method, in which a UE receives a measurement request sent by a network side device, and reports a measurement report value to the network side device. Compared with directly reporting a ranging and / or sidelink positioning measurement value of the UE, by reporting a measurement report value having a correspondence with the measurement value, the signaling overhead caused by reporting the measurement result can be reduced, and network resource waste can be reduced.

[0078] In one embodiment, the correspondence is related to reporting granularity.

[0079] Here, the reporting granularity of the distance measurement value refers to the minimum unit of the reported distance measurement value.

[0080] The reporting granularity of the distance measurement value refers to the minimum unit of the reported distance measurement value.

[0081] For example, the minimum unit of the reported distance measurement value can be 100 cm, 1 m, or 2 m, etc.

[0082] The reporting granularity of the azimuth angle measurement value refers to the minimum unit of the reported azimuth angle measurement value.

[0083] For example, the minimum unit of the reported azimuth angle measurement value can be 10 degrees, 20 degrees, or 30 degrees, etc.

[0084] The reporting granularity can reflect the reporting accuracy of the ranging and / or sidelink positioning measurement value. The larger the reporting granularity, the lower the reporting accuracy, and vice versa, the smaller the reporting granularity, the higher the reporting accuracy.

[0085] In some embodiments, the reporting granularity is determined according to a reporting granularity factor configured by a protocol or the network side device.

[0086] Here, the reporting granularity factor refers to a parameter that can affect the size of the reporting granularity.

[0087] Different reporting granularity factors correspond to different reporting granularities.

[0088] In some examples, the reporting granularity factor is positively correlated with the reporting granularity. That is, the larger the reporting granularity factor, the larger the reporting granularity; the smaller the reporting granularity factor, the smaller the reporting granularity.

[0089] In some examples, the relationship between the reporting granularity and the reporting granularity factor can be: M = 2 k where M represents the reporting granularity, and k represents the reporting granularity factor, and the value of k is an integer.

[0090] In one embodiment, the measurement report value has a corresponding relationship with the measurement value of the UE, which can include:

[0091] When the measurement value of the UE is greater than or equal to a first threshold value and less than a second threshold value, the measurement report value is a first value; wherein the difference between the second threshold value and the first threshold value is related to the reporting granularity.

[0092] In some examples, the first threshold value and the second threshold value can be determined according to the reporting granularity and the reporting range.

[0093] In some examples, the reporting range is a reporting range agreed by a protocol or configured by a network.

[0094] In some examples, the reporting range can be divided into a plurality of sub-ranges according to a reporting granularity. The difference between the maximum value and the minimum value of different sub-ranges corresponds to different measurement reporting values.

[0095] In an embodiment, the measurement reporting value corresponding to the measurement value of the UE can be an index value. For example, the index value is an integer. Since the measurement reporting value is an index value, the number of bits of the measurement reporting value is significantly smaller than the total number of bits of the measurement value of the UE, so as to further reduce the signaling overhead caused by reporting the measurement result and reduce the waste of network resources.

[0096] In an embodiment, the measurement value includes at least one of:

[0097] The measurement value of the UE's ranging includes a distance measurement value between the UE and the reference device, and / or an azimuth angle measurement value;

[0098] The measurement value of the UE's sidelink positioning includes a distance measurement value between the UE and the reference device, and / or an azimuth angle measurement value.

[0099] In some examples, the reference device can include a reference UE and / or a base station used as a reference point.

[0100] In some examples, the distance measurement value can be obtained by multiplying the transmission time of the ranging signal and / or the positioning reference signal (PRS) of the sidelink between the UE and the reference device by the speed of light.

[0101] In some examples, the azimuth angle can be an azimuth angle of arrival (AOA) or an azimuth angle of departure (AOD).

[0102] In some examples, the reporting granularity factor includes:

[0103] A first reporting granularity factor for determining the reporting granularity of the distance measurement value of the UE; the reporting granularity of the distance measurement value is used to determine the first correspondence relationship between the distance measurement value and the distance measurement reporting value with the distance reporting range;

[0104] And / or,

[0105] a second reporting granularity factor used to determine a reporting granularity of the azimuth measurement value of the UE; the reporting granularity of the azimuth measurement value is used to determine a second correspondence between the azimuth measurement value and an azimuth measurement report value with the azimuth reporting range.

[0106] In some examples, the distance reporting range and / or the azimuth reporting range can be determined according to a protocol agreement or a reporting configuration information sent by the network side device.

[0107] In some examples, the determination process of the first correspondence can include:

[0108] determining a reporting granularity of the distance measurement value according to the first reporting granularity factor, and determining a plurality of distance ranges according to the reporting granularity of the distance measurement value and the distance reporting range;

[0109] determining a correspondence between a plurality of distance report values and the plurality of distance ranges to obtain the first correspondence.

[0110] In some examples, the plurality of distance report values and the plurality of distance ranges have a one-to-one correspondence.

[0111] In some examples, the distance measurement report value corresponding to the distance measurement value can be a distance index. The distance index has an integer value.

[0112] In some examples, the reporting granularity of the distance measurement value and the first reporting granularity factor can have a relationship of M1=2 k1 wherein M1 represents the reporting granularity of the distance measurement value, and k1 represents the first reporting granularity factor, and the value of k1 is an integer.

[0113] 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, n first distance ranges can be determined between the minimum reporting distance and the maximum reporting distance, and a second distance range with an upper limit value of the minimum reporting distance and a third distance range with a lower limit value of the maximum reporting distance are determined. Wherein, when (y1-x1) / M1 is an integer, m is equal to (y1-x1) / M1; when (y1-x1) / M1 is not an integer, m is an integer value obtained by rounding up (y1-x1) / M1.

[0114] In some examples, the plurality of distance measurement report values corresponding to the second distance range, the m first distance ranges, and the third distance range are sequentially increased.

[0115] For example, the distance measurement report value corresponding to the second distance range is distance_0, the distance measurement report values corresponding to the first distance ranges are distance_1, distance_2, … distance_m in sequence, and the distance measurement report value corresponding to the third distance range is distance_m+1.

[0116] 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 can be updated at the same time or remain unchanged.

[0117] In some examples, the determination process of the second correspondence relationship can include:

[0118] determining the reporting granularity of the azimuth measurement value according to the second reporting granularity factor, and determining a plurality of azimuth ranges according to the reporting granularity of the azimuth measurement value and the azimuth reporting range;

[0119] determining the correspondence relationship between the plurality of azimuth report values and the plurality of azimuth ranges to obtain the second correspondence relationship.

[0120] In some examples, the azimuth measurement value and the azimuth measurement report value have a one-to-one correspondence relationship.

[0121] In some examples, the azimuth measurement report value corresponding to the azimuth measurement value can be a direction index. The value of the direction index is an integer.

[0122] In some examples, the relationship between the reporting granularity of the azimuth measurement value and the second reporting granularity factor can be M2=2 k2 wherein M2 represents the reporting granularity of the azimuth measurement value, and k2 represents the second reporting granularity factor, and the value of k2 is an integer.

[0123] For example, assuming that the reporting granularity of the azimuth measurement value determined according to the second reporting granularity factor is M2, the minimum reporting azimuth of the azimuth reporting range is x2, and the maximum reporting azimuth is y2, n first azimuth ranges can be determined between the minimum reporting azimuth and the maximum reporting azimuth, and a second azimuth range with an upper limit value of the minimum reporting azimuth and a third azimuth range with a lower limit value of the maximum reporting azimuth are determined. Wherein, when (y2-x2) / M2 is an integer, n is equal to (y2-x2) / M2; when (y2-x2) / M2 is not an integer, n is an integer value obtained by rounding up (y2-x2) / M2.

[0124] In some examples, the plurality of azimuth measurement report values corresponding to the second azimuth range, the n first azimuth ranges and the third azimuth range are sequentially increased.

[0125] For example, the azimuth measurement report value corresponding to the second azimuth range is distance_0, the distance measurement report values corresponding to the n first azimuth ranges are direction_1, direction_2, … direction_n in sequence, and the azimuth measurement report value corresponding to the third azimuth range is distance_n+1.

[0126] 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 of the azimuth reporting range and / or the minimum reporting azimuth angle can be updated or remain unchanged.

[0127] Figure 3 FIG. 1 is a flowchart of a measurement reporting method according to an example embodiment. The measurement reporting method is performed by a network side device, such as a location server, a gateway mobile location center (GMLC), an enhanced serving mobile location center (E-SMLC), a location management function (LMF), a base station, a user equipment (UE), and / or the like. Figure 3 As shown in FIG. 1, the measurement reporting method can include the following steps:

[0131] In some examples, the network side device can be a core network device, for example, the network side device can be a location management function (LMF) or a gateway mobile location center (GMLC) or an enhanced serving mobile location center (E-SMLC) or the like.

[0132] In other examples, the network side device can be a location server independent of an access network device and a core network device. The location server can interact with the UE through a service interface provided by the gateway mobile location center (GMLC).

[0133] It can be appreciated that the location management function (LMF), gateway mobile location center (GMLC), location server, etc. are only examples, and in other embodiments, can be replaced by other location server functions and / or base station functions, respectively.

[0134] The UE supports ranging and / or sidelink positioning. The UE can be a target UE for ranging and / or sidelink positioning.

[0135] In some examples, the measurement value of the UE for ranging and / or sidelink positioning is used to determine the relative position of one of the UE and the reference device relative to the other.

[0136] In some examples, the measurement value of the UE can be a measurement value between the UE and the reference device, or a measurement value between the UE and the assistance device.

[0137] In some examples, the measurement value of the UE includes a distance measurement value and / or an azimuth angle measurement value.

[0138] In some examples, in step 201, the network-side device can send a measurement request to the UE through an LTE positioning protocol (LPP) message or an NR positioning protocol (NRPP) message.

[0139] In some examples, the measurement request is used to request the UE to perform measurement reporting of ranging and / or sidelink positioning.

[0140] In some examples, the measurement request can include measurement configuration information and / or reporting configuration information.

[0141] The measurement configuration information is used to instruct the UE to perform ranging and / or sidelink positioning measurement.

[0142] The reporting configuration information is used to determine the correspondence between the measurement value of the UE and the measurement report value.

[0143] For example, the measurement request message can be NR-DL-TDOA-RequestLocationInformation (NR downlink time difference of arrival-RequestLocationInformation) or NR-DL-AoD-RequestLocationInformation (NR downlink azimuth angle of departure-RequestLocationInformation) in an information element (IE).

[0144] In some examples, in step 202, the network-side device can receive the measurement report value reported by the UE through an LPP message or an NRPP message.

[0145] For example, the measurement report value can be carried in an NR-DL-TDOA-SignalMeasurementInformation (NR downlink time difference of arrival-signal measurement information) or an NR-DL-AoD-SignalMeasurementInformation (NR downlink angle of departure-signal measurement information) in an IE.

[0146] In some examples, the measurement report value corresponding to the measurement value can be an index value. For example, the index value is an integer.

[0147] In some examples, the correspondence between the measurement value of the UE and the measurement report value can be a correspondence agreed upon by a protocol or configured by the network-side device.

[0148] In other examples, the correspondence between the measurement value of the UE and the measurement report value can be determined according to the measurement report information configured by the protocol or the network-side device.

[0149] The measurement report value can be determined according to the correspondence and the measurement value after the UE performs ranging and / or sidelink measurement according to the measurement request to obtain the measurement value.

[0150] In some examples, the correspondence can be one or more sets; different sets of the correspondence can be related to different reporting granularity factors, and can meet the mapping requirements of different ranging ranges and / or different ranging accuracies.

[0151] Embodiments of the present disclosure propose a measurement reporting method, in which a UE receives a measurement request sent by a network-side device and reports a measurement report value to the network-side device. Compared with directly reporting the measurement value of ranging and / or sidelink positioning of the UE, by reporting the measurement report value having a correspondence with the measurement value, the signaling overhead caused by reporting the measurement result can be reduced, and the waste of network resources can be reduced.

[0152] In one embodiment, the correspondence is related to reporting granularity.

[0153] Here, the reporting granularity refers to the minimum unit of the reported measurement value.

[0154] The reporting granularity of the distance measurement value refers to the minimum unit of the reported distance measurement value.

[0155] For example, the minimum unit of the reported distance measurement value can be 100 cm, 1 m, or 2 m, etc.

[0156] The reporting granularity of the azimuth measurement value is the minimum unit of the reported azimuth measurement value.

[0157] For example, the minimum unit of the reported azimuth measurement value can be 10 degrees, 20 degrees, or 30 degrees, etc.

[0158] The reporting granularity can reflect the reporting accuracy of the ranging and / or sidelink positioning measurement value. The greater the reporting granularity, the lower the reporting accuracy, and vice versa, the smaller the reporting granularity, the higher the reporting accuracy.

[0159] In some embodiments, the reporting granularity is determined according to a reporting granularity factor agreed by a protocol or configured by the network side device.

[0160] Here, the reporting granularity factor refers to a parameter that can affect the size of the reporting granularity.

[0161] Different reporting granularity factors correspond to different reporting granularities.

[0162] In some examples, the reporting granularity factor is positively correlated with the reporting granularity. That is, the greater the reporting granularity factor, the greater the reporting granularity; the smaller the reporting granularity factor, the smaller the reporting granularity.

[0163] In some examples, the relationship between the reporting granularity and the reporting granularity factor can be: M = 2 k where M represents the reporting granularity, and k represents the reporting granularity factor, and the value of k is an integer.

[0164] In one embodiment, the measurement report value has a corresponding relationship with the measurement value of the UE, which can include:

[0165] When the measurement value of the UE is greater than or equal to a first threshold value and less than a second threshold value, the measurement report value is a first value; wherein the difference between the second threshold value and the first threshold value is related to the reporting granularity.

[0166] In one embodiment, the measurement report value has a corresponding relationship with the measurement value of the UE, which includes:

[0167] When the measurement value of the UE is greater than or equal to a first threshold value and less than a second threshold value, the measurement report value is a first value; wherein the difference between the second threshold value and the first threshold value is related to the reporting granularity.

[0168] In some examples, the first threshold value and the second threshold value can be determined according to the reporting granularity and the reporting range.

[0169] In some examples, the reporting range is a reporting range agreed by a protocol or configured by a network. In some examples, the reporting range can be divided into multiple sub-ranges according to a reporting granularity. A difference between a maximum value and a minimum value of different sub-ranges corresponds to different measurement reporting values.

[0170] In an embodiment, the measurement reporting value corresponding to the measurement value can be an index. For example, the index is an integer. Since the measurement reporting value is an index, the number of bits of the measurement reporting value is significantly less than the total number of bits of the measurement value, so as to further reduce the signaling overhead caused by reporting the measurement result and reduce the waste of network resources.

[0171] In an embodiment, the measurement value includes at least one of:

[0172] The measurement value of the UE's ranging includes a distance measurement value between the UE and a reference device, and / or an azimuth angle measurement value;

[0173] The measurement value of the UE's sidelink positioning includes a distance measurement value between the UE and a reference device, and / or an azimuth angle measurement value.

[0174] In some examples, the reference device can include a reference UE and / or a base station used as a reference point.

[0175] In some examples, the distance measurement value can be obtained by multiplying a transmission time of a ranging signal and / or a positioning reference signal (PRS) of a sidelink between the UE and the reference device by the speed of light.

[0176] In some examples, the azimuth angle can be an azimuth angle of arrival (AOA) or an azimuth angle of departure (AOD).

[0177] In some examples, the reporting granularity factor includes:

[0178] A first reporting granularity factor for determining a reporting granularity of the distance measurement value of the UE; the reporting granularity of the distance measurement value is used to determine a first correspondence relationship between the distance measurement value and a distance measurement reporting value with a distance reporting range;

[0179] and / or,

[0180] A second reporting granularity factor is used to determine a reporting granularity of the azimuth measurement value of the UE; the reporting granularity of the azimuth measurement value is used to determine a second correspondence between the azimuth measurement value and an azimuth measurement report value with the azimuth reporting range.

[0181] In some examples, the distance reporting range and / or the azimuth reporting range can be determined according to a protocol agreement or reporting configuration information sent by the network side device.

[0182] In some examples, the determination process of the first correspondence can include:

[0183] A reporting granularity of the distance measurement value is determined according to the first reporting granularity factor, and a plurality of distance ranges are determined according to the reporting granularity of the distance measurement value and the distance reporting range.

[0184] A correspondence between a plurality of distance report values and a plurality of distance ranges is determined to obtain the first correspondence.

[0185] In some examples, the plurality of distance report values and the plurality of distance ranges have a one-to-one correspondence.

[0186] In some examples, the distance measurement report value corresponding to the distance measurement value can be a distance index. The distance index has an integer value.

[0187] In some examples, the reporting granularity of the distance measurement value and the first reporting granularity factor can have a relationship of M1=2 k1 wherein M1 represents the reporting granularity of the distance measurement value, and k1 represents the first reporting granularity factor, and the value of k1 is an integer.

[0188] 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, n first distance ranges can be determined between the minimum reporting distance and the maximum reporting distance, and a second distance range with an upper limit value of the minimum reporting distance and a third distance range with a lower limit value of the maximum reporting distance are determined. Wherein, when (y1-x1) / M1 is an integer, m is equal to (y1-x1) / M1; when (y1-x1) / M1 is not an integer, m is an integer value obtained by rounding up (y1-x1) / M1.

[0189] In some examples, the plurality of distance measurement report values corresponding to the second distance range, the m first distance ranges, and the third distance range are sequentially increased.

[0190] For example, the distance measurement report value corresponding to the second distance range is distance_0, the distance measurement report values corresponding to the first distance ranges are distance_1, distance_2, … distance_m in sequence, and the distance measurement report value corresponding to the third distance range is distance_m+1.

[0191] 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 can be updated at the same time or remain unchanged.

[0192] In some examples, the determination process of the second correspondence relationship can include:

[0193] The reporting granularity of the azimuth measurement value is determined according to the second reporting granularity factor, and a plurality of azimuth ranges are determined according to the reporting granularity of the azimuth measurement value and the azimuth reporting range.

[0194] A correspondence relationship between a plurality of azimuth report values and a plurality of azimuth ranges is determined to obtain the second correspondence relationship.

[0195] In some examples, the azimuth measurement value and the azimuth measurement report value have a one-to-one correspondence relationship.

[0196] In some examples, the azimuth measurement report value corresponding to the azimuth measurement value can be a direction index. The value of the direction index is an integer.

[0197] In some examples, the relationship between the reporting granularity of the azimuth measurement value and the second reporting granularity factor can be M2=2 k2 wherein M2 represents the reporting granularity of the azimuth measurement value, and k2 represents the second reporting granularity factor, and the value of k2 is an integer.

[0198] For example, assuming that the reporting granularity of the azimuth measurement value determined according to the second reporting granularity factor is M2, the minimum reporting azimuth of the azimuth reporting range is x2, and the maximum reporting azimuth is y2, n first azimuth ranges can be determined between the minimum reporting azimuth and the maximum reporting azimuth, and a second azimuth range with an upper limit value of the minimum reporting azimuth and a third azimuth range with a lower limit value of the maximum reporting azimuth are determined. Wherein, when (y2-x2) / M2 is an integer, n is equal to (y2-x2) / M2; when (y2-x2) / M2 is not an integer, n is an integer value obtained by rounding up (y2-x2) / M2.

[0199] In some examples, the plurality of azimuth measurement report values corresponding to the second azimuth range, the n first azimuth ranges and the third azimuth range are sequentially increased.

[0200] For example, the azimuth measurement report value corresponding to the second azimuth range is distance_0, the distance measurement report values corresponding to the n first azimuth ranges are direction_1, direction_2, … direction_n in sequence, and the azimuth measurement report value corresponding to the third azimuth range is distance_n+1.

[0201] 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 of the azimuth reporting range and / or the minimum reporting azimuth angle can be updated or kept unchanged.

[0202] To further explain any embodiment of the present disclosure, several specific embodiments are provided below.

[0203] An information processing method is provided in the embodiments of the present disclosure, and the method can include the following steps.

[0204] S1: A network side device configures measurement and reporting configuration information of ranging to a UE through a first message.

[0205] The network side device can be a location server.

[0206] Here, the first message can be an LPP message or an NRPP message. For example, the first message can be NR-DL-TDOA-RequestLocationInformation (NR downlink time difference of arrival-RequestLocationInformation) or NR-DL-AoD-RequestLocationInformation (NR downlink angle of departure-RequestLocationInformation) in an information element (IE).

[0207] The reporting configuration information at least includes a reporting granularity factor k1 (for example, the first reporting granularity factor in the above embodiments) and a reporting granularity factor k2 (for example, the second reporting granularity factor in the above embodiments) of distance and / or azimuth for ranging measurement reporting, and 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.

[0208] S2: The UE reports the measurement result of the distance and azimuth value relative to the reference point to the location server through a second message.

[0209] The second message can be an LPP message or an NRPP message. For example, the second message can be: NR-DL-TDOA-SignalMeasurementInformation (NR downlink time difference of arrival-signal measurement information) in an IE or NR-DL-AoD-SignalMeasurementInformation (NR downlink azimuth of departure-signal measurement information) in an IE.

[0210] When reporting the measurement result, the UE maps the measurement result and reports a measurement report value of the measurement result mapping. The mapping of the measurement result reporting is as follows:

[0211] Suppose the reporting range of the distance measurement value is [x1, y1], and the reporting granularity size is 2 k1 , which can be in meters or centimeters. For example, if the value of k1 is -1, the reporting mapping of the distance measurement value is as follows:

[0212]

[0213] It can be understood that each element in the above table exists independently, and 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 independent of 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.

[0214] It can be understood that for the reporting of the distance, the value of k1 can be set according to actual needs. In some examples, the k1 can take a positive integer value, for example, k1 is 5, and the unit is centimeter, then the reporting granularity is 32 centimeters. In some other examples, the k1 can take a negative integer value, for example, k1 is -2, and the unit is meter, then the reporting granularity is 0.25m; for example, k1 is -3, then the reporting granularity is 0.125m.

[0215] Suppose the reporting range of the azimuth measurement value is [x2, y2], and the reporting granularity size is 2 k2 , which can be in degrees or radians.

[0216] For example, if the value of k2 is 1, the reporting mapping of the azimuth measurement value is as follows:

[0217]

[0218] It can be understood that each element in the above table exists independently, and the 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 independent of 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.

[0219] 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, the value of k1 can be a positive integer, for example, the value of k2 can be 0, 1, 2, and the reporting granularity is 1 degree, 2 degrees and 4 degrees respectively.
