In order to enable those skilled in the art to better understand the technical solutions of the embodiments of the present disclosure, the following description is first made.

Observed Time Difference of Arrival (OTDOA) is a positioning method defined by 3GPP protocol specifications. The basic principle of OTDOA is: the User Equipment (UE) measures the downlink positioning reference signal (Positioning Reference Signal, PRS) sent from multiple transmission points (Transmission Point, TP), and may also include the downlink reference signal (Downlink Reference Signals). , DL-RS) to obtain reference signal time difference (RSTD) measurement values arriving at the UE, and report them to the positioning server in the network to estimate the location of the UE. The positioning server is called a local management function (Location Management Function, LMF) in the New Generation Radio Access Network (NG-RAN).

In the OTDOA positioning process, the LMF needs to first obtain the OTDOA auxiliary information associated with the cell from the base station (Base station, BS) through the positioning protocol specified by 3GPP, such as NRPPa (NR Positioning Protocol A, NRPPa), such as: physical cell ID, The antenna position and PRS configuration of the cell. Then, the UE obtains OTDOA auxiliary information for supporting RSTD measurement from the LMF through a positioning protocol specified by 3GPP, such as LPP (LTE Positioning Protocol, LPP).

The OTDOA basic positioning process including "UE-triggered positioning information transmission process" and "LMF-triggered positioning information transmission process" includes the following 11 steps:

(1) After the UE establishes a connection with the BS, the UE is in a radio resource control connection (RRC_CONNECTED) state.

(2) The positioning server sends a "request positioning capability" message to the UE, requesting the UE to notify the server of the positioning functions that the UE can support.

(3) The UE responds to the positioning server by sending a "provide positioning capability" message. The "Provide Positioning Capability" message reports that the UE means that the terminal supports the positioning capabilities of NG-RAN and OTDOA.

(4) When the downlink positioning assistance data is needed, the UE sends a "request positioning assistance data" message to the positioning server. This message includes requesting the positioning server to provide OTDOA assistance data.

(5) The positioning server sends an "OTDOA Information Request (NRPPa OTDOA INFORMATION REQUEST)" message to the BS, which requests the BS to provide downlink positioning assistance data, such as PRS configuration data.

(6) The BS sends an "OTDOA information response (NRPPa OTDOA INFORMATION RESPONSE)" message to the positioning server. Provide the requested downlink positioning assistance data to the positioning server, including PRS configuration data.

(7) The positioning server provides the positioning assistance data requested by the UE in the "provide positioning assistance data" message, which carries PRS configuration data.

(8) The positioning server sends a "request positioning information" message to the UE. This message requests the UE to measure the downlink PRS of the BS and responds with the measured positioning measurement value.

(9) The UE uses positioning assistance data (for example: PRS configuration data) to measure the downlink signal to obtain a positioning measurement value (for example: RSTD).

(10) The UE sends a "provide positioning information" message to the positioning server, which includes the positioning measurement value obtained by measuring the downlink PRS (for example: RSTD).

(11) The positioning server uses the positioning measurement values obtained by the UE to calculate the position of the UE.

It should be noted that in terms of time, (5) and (6) and (1) to (4) do not have a sequence relationship. That is: (5) and (6) may occur before, after, or at the same time (1) to (4).

"LMF-triggered positioning information transmission process" includes all 11 steps; "UE-triggered positioning information transmission process" includes 10 steps except (8).

The above describes the transmission process of positioning information in the LTE system, but there is currently no relevant solution for the reporting method of the positioning measurement in the NR system.

Based on this, as shown in FIG. 2, an embodiment of the present disclosure provides a method for reporting a positioning measurement value, which is applied to a terminal, and includes:

Step 201: Obtain measurement configuration information, where the measurement configuration information includes S positioning reference signal PRS resources and the reported quantity K of target measurement quantities.

Step 202: Perform measurement on the S PRS resources to obtain N target measurement quantities.

In the embodiment of the present disclosure, after receiving the measurement configuration information, the terminal measures each of the PRS resources to obtain N target measurement quantities.

Step 203: Report the M target measurement quantities.

Here, the terminal may report the M target measurement quantities according to different quantization precisions, or may report a target measurement quantity less than the number configured on the network side, so as to reduce the reporting overhead of the terminal.

According to the method for reporting positioning measurement quantities in the embodiments of the present disclosure, measurement configuration information is obtained, and the measurement configuration information includes S positioning reference signal PRS resources and the reported quantity K of target measurement quantities; the S PRS resources are measured to obtain N target measurement quantities; report the M target measurement quantities, thereby realizing the reporting of positioning measurement quantities, and in the embodiments of the present disclosure, target measurement quantities less than the number configured on the network side can be reported, which can effectively reduce terminal reporting overhead .

Further, the reporting the M target measurement quantities includes:

Here, the measurement quality indicator of the target measurement quantity is used to indicate the quality of the RSTD measurement. For example, the predefined RSTD measurement quality indicator in the system is divided into a first level and a second level. Report the measurement quality indicator of the target measurement quantity so that the network device can determine the quantization accuracy of the target measurement quantity or the number of the target measurement quantity reported by the terminal according to the measurement quality indicator. That is to say, the value of M or the quantization accuracy of M target measurement quantities in the embodiment of the present disclosure is determined according to M measurement quality indicators.

The measurement quality indication may include the number of samples used to calculate the measurement volume, the uncertainty indication of the measurement volume, and the like. Among them, the higher the number of samples and the lower the uncertainty, the higher the measurement quality indicator level.

Specifically, the reporting the measurement values and target information corresponding to the M target measurement quantities includes:

Encode the target information to obtain the first reported information;

Further, reporting the measurement values corresponding to the M target measurement quantities includes:

Here, the measurement values corresponding to the M target measurement quantities are reported according to different quantization accuracy, which can effectively reduce the reporting overhead of the terminal.

Specifically, reporting the measurement values corresponding to the M target measurement quantities according to different quantization precisions includes:

For example, the embodiments of the present disclosure are classified into high-precision quantization and low-precision quantization. High-precision quantization is used for the target measurement quantity indicated as the first level of measurement quality, such as 12-bit quantization, and the target measurement quantity indicated as the second level of the measurement quality The measurement quantity is quantized with low precision, such as 8-bit quantization, instead of quantization according to a uniform quantization precision, so as to achieve the purpose of reducing terminal reporting overhead.

Further, in the embodiments of the present disclosure, N≥K, and M<K.

That is, in the specific embodiment of the present disclosure, the terminal reports a target measurement quantity that is less than the number configured on the network side, so as to reduce the reporting overhead of the terminal.

Further, the value of M is equal to the number of first target measurement quantities among the N target measurement quantities;

For example, the pre-defined RSTD measurement quality indicators in the system are divided into the first level and the second level, where the quality of the first level is better than the second level, and the above-mentioned preset threshold may be specifically the value corresponding to the first level, that is, N Among the target measurement quantities, M target measurement quantities whose measurement quality indicator is the first level are reported to the network device.

Further, in the method for reporting positioning measurement quantities of the embodiment of the present disclosure, the reporting of the M target measurement quantities includes:

Further, the reporting the M target measurement quantities includes:

The M target measurement quantities are reported in a differential manner.

Specifically, the difference value of each of the M target measurement quantities and the reference value and the reference value are reported.

Wherein, the reference value is the maximum value, the minimum value of the M target measurement quantities, or the average value of the M target measurement quantities, and the difference value and the reference value adopt different quantization precisions.

In the method for reporting positioning measurement quantities in the embodiments of the present disclosure, the terminal can report measurement quantities less than the number configured on the network side, or report multiple measurement quantities with different quantization precisions, thereby effectively reducing the terminal's reporting overhead.

As shown in FIG. 3, the embodiment of the present disclosure also provides a method for reporting positioning measurement, which is applied to network equipment, including:

Step 301: Send measurement configuration information to the terminal, where the measurement configuration information includes S positioning reference signal PRS resources and the reported quantity K of target measurement quantities.

Step 302: Obtain M target measurement quantities reported by the terminal.

In the embodiment of the present disclosure, after receiving the measurement configuration information, the terminal measures each of the PRS resources to obtain N target measurement quantities, and reports the M target measurement quantities according to different quantization precisions, or Report a target measurement volume smaller than the number configured on the network side to reduce the reporting overhead of the terminal.

According to the method for reporting positioning measurement quantities in the embodiment of the present disclosure, measurement configuration information is sent to the terminal, and the S PRS resources are measured to obtain N target measurement quantities; and the M target measurement quantities reported by the terminal are acquired, So as to realize the reporting of positioning measurement volume.

Further, acquiring the M target measurement quantities reported by the terminal includes:

Further, the obtaining the M measurement values and target information corresponding to the target measurement quantities reported by the terminal includes:

Obtain the first reported information and the second reported information;

In the specific embodiment of the present disclosure, the measurement value and the target information corresponding to the target measurement quantity are divided into different parts, and each part is independently coded and reported.

The method for reporting positioning measurement quantities of the present disclosure will be described below in conjunction with specific embodiments.

Example one:

The network side configures the terminal to measure S=30 PRS resources, and the PRS resources correspond to different or the same cells, and the network side configures the terminal to report K=20 RSTD measurement values of different cells.

(1) The terminal receives the configuration of the network, measures each PRS resource separately, and obtains the measurement results of the time of arrival (TOA) of N=25 (N≤S) different cells.

(2) The terminal calculates N-1=24 RSTD measurement values from N=25 TOA results, where each RSTD measurement value is the difference between the TOA value of this resource and the TOA value of the reference resource.

(3) The terminal determines the RSTD measurement quality indicator corresponding to each of the N-1=24 RSTD measurement values, which is used to indicate the quality of the RSTD measurement. For example, the pre-defined RSTD measurement quality indicator in the system is divided into a first level and a second level, where the quality of the first level is better than the second level.

(4) The terminal only reports the RSTD measurement value corresponding to the first level to the network side. For example, define RSTD _{i to} represent the i-th RSTD measurement value, where i=1, 2,..., N-1. If the terminal determines that the measurement quality indicator corresponding to the RSTD _i with i=1, 2, 3, 5, 8, 9 is the first level, and the other RSTDs are the second level. Then the terminal only reports M=6 RSTDs indicating the measurement quality as the first level to the network side, and at the same time reports M=6 to the network. Since the number M of RSTDs reported by the terminal side is less than the number of RSTDs configured on the network side, in order for the network side to decode correctly, it is necessary to report M=6 as the first part to the network and RSTD as the second part to the network.

(5) The RSTD is reported in a differential manner.

Among them, the reference value RSTD _ref = min{RSTD _i , i = 1, 2, 3, 5, 8, 9}, (M-1) differential values are expressed as:

The reference value can be quantized in high bits, and the difference value can be quantized in low bits.

(6) The network side receives the reports of the first part and the second part. According to the decoding of the first part, M=6 is obtained, and then it is determined that the second part contains 6 RSTDs, and then the second part is decoded to obtain (M-1) difference values

And a reference value RSTD _ref .

In this embodiment, the terminal reports a measurement quantity that is less than the number configured on the network side, that is, reports the target measurement quantity whose measurement quality is indicated as the first level to the terminal, so as to reduce the reporting overhead of the terminal.

Embodiment two:

(3) The terminal determines the RSTD measurement quality indicator corresponding to each of the N-1=24 RSTD measurement values, which is used to indicate the quality of the RSTD measurement. For example, the pre-defined RSTD measurement quality indicator in the system is divided into a first level and a second level, where the quality of the first level is better than the second level. The terminal determines that the measurement quality indicator corresponding to the RSTD _i with i=1, 2, 3, 5, 8, 9 is the first level, and the remaining RSTDs are the second level.

(4) The terminal reports K0=6 RSTD measurement values corresponding to the first level and K-K0=14 RSTD measurement values corresponding to the second level to the network side. For example, the terminal determines to report RSTD _{i with} i=1, 2, ..., 20 to the network side, and at the same time, the terminal reports the RSTD measurement quality indicator corresponding to this K=20 RSTD measurement values to the network side. In order for the network side to be able to decode correctly, it is necessary to report K=20 RSTD measurement quality indicators to the network as the first part, and report the RSTD measurement values to the network as the second part.

(5) The RSTD is reported in a differential manner.

Among them, the reference value RSTD _ref =min{RSTD _i , i=1, 2, ..., 20}, (K-1) differential values are expressed as:

Among them, the difference value uses high-precision quantization and low-precision quantization according to the corresponding RSTD measurement quality. For example for

12-bit quantization is used, and for

Use 8-bit quantization.

(6) The network side receives the reports of the first part and the second part. According to the decoding of the first part, the measurement quality indicator of each of the K=20 RSTD measurement values is obtained, and the second part is determined to contain 6 high-precision quantized RSTDs and 13 low-precision quantized RSTDs. Perform decoding to get K-1=19 difference values

And a reference value RSTD _ref .

In this embodiment, the terminal reports the target measurement quantity according to different quantization accuracy, that is, the target measurement quantity indicated as the first level of measurement quality is reported with high-precision quantization, and the measurement quality indication is indicated as the target measurement quantity of the second level with low precision. Quantify the reporting to reduce the reporting overhead of the terminal.

Of course, in the embodiments of the present disclosure, when reporting target measurement quantities that are less than the number configured on the network side, the reporting is performed according to different quantization precisions.

In the method for reporting positioning measurement quantities in the embodiments of the present disclosure, the terminal can report measurement quantities less than the number configured on the network side, or report multiple measurement quantities with different quantization accuracy, or combine the above two methods, which can be effective Reduce terminal reporting overhead.
