The NR defines a corresponding positioning measurement for each positioning technique, as follows:

(1) NR DL-TDOA: the terminal reports the DL relative signal time difference (Relative Signal Time Difference, RSTD).

(2) NR DL-AoD: the terminal reports DL PRS reference signal received power (Reference Signal Received Power, RSRP).

(3) NR UL-TDOA: the network device reports the relative arrival time (Relative Time of Arrival, RTOA).

In the positioning technology, the DL-TDOA, the UL-TDOA and the Multi-RTT report time measurement values, and the time measurement values are adopted for position calculation; the DL-AoD and UL-AoA use angle measurements for position resolution.

Alternatively, the second communication device may be any communication device that performs a positioning solution. For example, the second communication device may comprise a positioning server and/or a terminal.

For example, for a downlink positioning scenario, the first communication device may be a terminal. The second communication device may be a location server, such as a location management function network element (Location Management Function, LMF).

For example, for an uplink positioning scenario, the first communication device may be a network device. The second communication device may be a location server.

For example, for an uplink and downlink hybrid positioning scenario, the first communication device may be a terminal and/or a network device. The second communication device may be a location server.

For example, for a direct communication link (SL) positioning scenario, the first communication device may be a terminal for other assisted positioning than the terminal to be positioned. The second communication device may be a terminal to be located.

Taking the positioning measurement quantity as A-AoA and taking the first communication device as a network device as an example, the first communication device can carry out smoothing treatment on the original measurement value of A-AoA according to the smoothing information of A-AoA after measuring to obtain the original measurement value of A-AoA, for example, the first communication device can average the original measurement value of A-AoA obtained by the current latest measurement and the original measurement value of A-AoA obtained by the previous multiple measurements to obtain a smoothed measurement value of A-AoA corresponding to the current latest measurement; or the original measured value of A-AoA obtained by the current latest measurement and the smooth measured value of A-AoA corresponding to the previous measurement or the previous measurements are weighted and summed to obtain the smooth measured value of A-AoA corresponding to the current latest measurement; or any other smoothing method, etc., without specific limitation.

Alternatively, the first communication device may determine the smoothed information of the positioning measurement quantity by itself.

Optionally, the determining, by the first communication device, the smoothing information of the positioning measurement quantity may include: smoothing information of the positioning measurement is received. That is, the first communication device may acquire the smoothed information of the positioning measurement amount from the other communication device. For example, the first communication device may receive smoothing information of the positioning measurement from the second communication device; or the first communication device may receive the smoothing information of the positioning measurement quantity from other communication devices, for example, in a SL positioning scenario, the terminal assisting in positioning may receive the smoothing information of the positioning measurement quantity sent by the terminal to be positioned, or may receive the smoothing information of the positioning measurement quantity sent by the positioning server in a network coverage situation.

Alternatively, the smoothing information of the positioning measurement quantity may be associated with the type of positioning measurement quantity. That is, each positioning measurement may have its own corresponding smoothing information. For example, the positioning measurement RSTD may correspond to the smoothing information a, and the positioning measurement RSRP may correspond to the smoothing information B.

After the first communication device obtains the smooth measured value of the positioning measured value according to the smooth information of the positioning measured value, the obtained smooth measured value can be reported to the second communication device, and the second communication device can carry out positioning calculation according to the smooth measured value reported by the first communication device, so that the influence on a positioning result when the single measurement error is larger can be avoided, and the positioning precision is improved.

For example, each smooth measurement value determined by the first communication device may be associated with a timestamp, and each smooth measurement value reported by the first communication device to the second communication device corresponds to a measurement time, which indicates a smooth measurement value obtained by smoothing an original measurement value measured by the corresponding measurement time.

According to the measurement method for positioning provided by the embodiment of the application, the first communication equipment can carry out smoothing treatment on the original measured value of the positioning measurement quantity after measuring the original measured value of the positioning measurement quantity according to the smoothing information of the positioning measurement quantity to obtain the smoothed measured value of the positioning measurement quantity, and report the smoothed measured value to the second communication equipment for positioning calculation, so that the influence of single measurement errors on a positioning result can be avoided, and the positioning precision can be improved.

For example, the smoothing indication parameter may perform smoothing processing by using an ON indication, and then the first communication device may perform smoothing processing ON the raw measurement value of the positioning measurement value after measuring the raw measurement value of the positioning measurement value, and report the smoothed measurement value.

For example, the smoothing indication parameter may indicate that the smoothing is not performed by using the OFF indication, and then the first communication device may not perform smoothing processing on the raw measurement value of the positioning measurement value after measuring the raw measurement value of the positioning measurement value, and report the raw measurement value.

(2) A smoothing number indicating smoothing using the original measurement value of the target number.

Optionally, the target number is the smoothed number indicated in the above smoothing information.

For example, if the number of smoothing is N (N is an integer greater than 1), the first communication device may perform smoothing processing using N raw measurement values of a positioning measurement value when calculating a smoothed measurement value of the positioning measurement value, to obtain a smoothed measurement value. Alternatively, the N raw measurements of the positioning measurement may be N measurements.

(3) Smoothing filter coefficients indicating relevant parameters for determining the smoothed measurement value.

For example, the first communication device may determine a smoothed measurement value of the positioning measurement quantity based on the smoothing filter coefficient indicated by the smoothing information after measuring the raw measurement value of the positioning measurement quantity.

For example, after N measurements are performed to obtain N raw measurement values of the positioning measurement values, the first communication device may perform weighted summation on the N raw measurement values according to the smoothing filter coefficients, that is, each raw measurement value is multiplied by a corresponding smoothing filter coefficient and summed to obtain a smoothed measurement value of the positioning measurement value.

For example, the smoothing information of the positioning measurement amount indicates that the smoothing process is performed on the raw measurement value of the positioning measurement amount from the start of the time stamp Timestamp1 to the last measurement. For example, indicating that Timestamp 1=15, the first communication device may perform smoothing processing on the raw measurement value of the positioning measurement amount from the time point of Timestamp 1=15 to the current time point, to obtain a smoothed measurement value of the positioning measurement amount corresponding to the current last measurement.

(5) And a smoothed threshold value, wherein the threshold value is used for indicating that the original measured value meeting the target threshold condition is used for smoothing.

Alternatively, the target gate condition may be determined according to a smoothed threshold value indicated by the smoothing information. The original measured value meeting the target threshold condition may include the original measured value itself being higher than a threshold value indicated by the smoothing information; or may include that a certain measurement corresponding to the raw measurement is above a threshold indicated by the smoothing information; or other threshold conditions, etc.

For example, the smoothed threshold value indicates a threshold value S1 of the TOA, and the first communication device may perform smoothing processing using an original measurement value of the TOA higher than the threshold value S1 when calculating the smoothed measurement value of the TOA.

For example, the smoothed threshold value indicates a threshold value S2 of RSRP, and the first communication device may perform smoothing processing using an original measurement value of TOA having a corresponding RSRP higher than the threshold value S2 when calculating the smoothed measurement value of TOA.

For example, for a downlink location scenario, the second communication device may be a location server, such as an LMF.

For example, for an uplink positioning scenario, the second communication device may be a positioning server.

For example, for an uplink and downlink hybrid location scenario, the second communication device may be a location server.

For example, for a SL positioning scenario, the second communication device may be a terminal to be positioned.

In the embodiment of the application, the second communication equipment can determine the smooth measured value of the positioning measurement quantity and perform positioning calculation according to the determined smooth measured value of the positioning measurement quantity, thereby avoiding the influence on the positioning result when the single measurement error is larger and being beneficial to improving the positioning precision.

Optionally, the determining, by the second communication device, a smoothed measurement of the positioning measurement may include:

Alternatively, the second communication device may calculate a smoothed measurement value of the positioning measurement amount from the smoothed information of the positioning measurement amount after measuring the original measurement value of the positioning measurement amount, and perform positioning calculation using the smoothed measurement value.

For example, for a SL positioning scene, the terminal to be positioned may measure the arrival angle AoA of the SL-PRS, and then perform smoothing processing on the measurement result of the AoA according to the smoothing information of the AoA, to obtain a smoothed measurement value of the AoA, and use the smoothed measurement value of the AoA to perform positioning calculation.

Alternatively, when the calculation of the smoothed measurement value is performed, if the first smoothed measurement value needs to be calculated, the second communication device may perform smoothing processing using the raw measurement value of the positioning measurement value, to obtain the first smoothed measurement value.

When the calculation of the smoothed measurement value is performed, if the second smoothed measurement value needs to be calculated, the second communication device may perform smoothing processing by using the raw measurement value of the positioning measurement value and the corresponding carrier phase measurement value, to obtain the second smoothed measurement value.

For example, for a downlink positioning scenario, the first communication device may be a terminal.

For example, for an uplink positioning scenario, the first communication device may be a network device.

For example, for an uplink and downlink hybrid positioning scenario, the first communication device may be a terminal and/or a network device.

For example, for a SL positioning scenario, the first communication device may be a terminal for other assisted positioning than the terminal to be positioned.

Optionally, when performing positioning measurement, the first communication device may determine smoothing information of the positioning measurement quantity to be measured first, and after measuring to obtain an original measurement value of the positioning measurement quantity, may perform smoothing processing on the original measurement value of the positioning measurement quantity according to the smoothing information to obtain a corresponding smoothed measurement value. Then, the first communication device can report the obtained smooth measured value to the second communication device, and the second communication device can perform positioning calculation according to the smooth measured value reported by the first communication device, so that the influence on a positioning result when a single measurement error is larger can be avoided, and the positioning precision is improved.

For example, the smoothing indication parameter may adopt ON indication to perform smoothing processing, and then the first communication device or the second communication device may perform smoothing processing ON the original measurement value of the positioning measurement value after measuring the original measurement value of the positioning measurement value, and report the smoothed measurement value.

For example, the smoothing indication parameter may indicate that the smoothing is not performed by using the OFF indication, and then the first communication device or the second communication device may not perform smoothing processing on the raw measurement value of the positioning measurement value after measuring the raw measurement value of the positioning measurement value, and report the raw measurement value.

For example, if the smoothing number is N (N is an integer greater than 1), the first communication device or the second communication device may perform smoothing processing using N raw measurement values of a certain positioning measurement value when calculating a smoothed measurement value of the positioning measurement value, to obtain a smoothed measurement value. Alternatively, the N raw measurements of the positioning measurement may be N measurements.

For example, the first communication device or the second communication device may determine a smoothed measurement value of the positioning measurement quantity based on the smoothing filter coefficient indicated by the smoothing information after measuring the raw measurement value of the positioning measurement quantity.

For example, after N measurements are performed to obtain N raw measurement values of the positioning measurement values, the first communication device or the second communication device may perform weighted summation on the N raw measurement values according to the smoothing filter coefficient, that is, each raw measurement value is multiplied by a corresponding smoothing filter coefficient and summed to obtain a smoothed measurement value of the positioning measurement value.

For example, the smoothing information of the positioning measurement amount indicates that the smoothing process is performed on the raw measurement value of the positioning measurement amount from the start of the time stamp Timestamp1 to the last measurement. For example, indicating that Timestamp 1=15, the first communication device or the second communication device may perform smoothing processing on the raw measurement value of the positioning measurement amount from the time point of Timestamp 1=15 to the current time point, to obtain a smoothed measurement value of the positioning measurement amount corresponding to the current last measurement.

For example, the smoothed threshold value indicates a threshold value S1 of the TOA, and the first communication device or the second communication device may perform smoothing processing using an original measurement value of the TOA higher than the threshold value S1 when calculating the smoothed measurement value of the TOA.

For example, the smoothed threshold value indicates a threshold value S2 of RSRP, and the first communication device or the second communication device may perform smoothing processing using an original measurement value of TOA corresponding to RSRP higher than S2 when calculating the smoothed measurement value of TOA.

According to the measuring method for positioning, the second communication device can determine the smooth measured value of the positioning measurement quantity and perform positioning calculation according to the smooth measured value, so that the influence of single measurement errors on a positioning result can be avoided, and the positioning accuracy can be improved.

And when the terminal performs measurement reporting, measuring all PRS resources sent by each network device. The first path TOA of the best one PRS resource, such as the first path TOA of PRS resource 2, is determined, for example, among the y=8 PRS resources transmitted by network device 2. According to the configuration of the positioning server, the smoothed measurement value of the TOA is obtained by performing N measurements on PRS resource 2 to obtain toa_0, toa_1, …, toa_ (N-1), and smoothing the toa_ (N-1)) by using a smoothing filter coefficient (a (0), a (1), …, a (N-1)), where the following formula is shown:

smooth measurement of TOA = a (0) toa_0+a (1) toa_1+ … +a (N-1) toa_n-1

The N times of measurement results can be obtained by combining the latest N-1 times of measurement results stored by the terminal with the current measurement results. If the positioning server does not indicate a smoothing filter coefficient and is configured to need smoothing, each smoothing filter coefficient may take a value of 1/N.

In another implementation, the smoothing information of the positioning measurement quantity indicates that the positioning measurement quantity started by the Timestamp1 is smoothed until the last measurement. For example, timestamp 1=15 is indicated, so that after receiving the smoothing information, the terminal may smooth the positioning measurement values from the time point of Timestamp 1=15 to the current time, for example, average the positioning measurement values to obtain a smoothed measurement value or multiply each of the positioning measurement values by a corresponding smoothing filter coefficient to obtain a smoothed measurement value.

In another implementation, the TOA corresponding to the measured TOA is smoothed above the threshold T (the value of T is indicated in the smoothing information), and similar to the above formula, for example, the TOAs may be averaged to obtain a smoothed measurement value. And reporting the difference value between the calculated smoothed measurement value of the TOA and the smoothed measurement value of the TOA of the reference resource as RSTD of the network equipment 2. The reference resource may be configured by a positioning server and the smoothed measurement of the TOA of the reference resource is also calculated in the same smoothed manner as the smoothed measurement of the TOA. Other network devices are similar to this and will not be described in detail. And after receiving the RSTD measurement report of the terminal, the positioning server performs position calculation of the terminal and determines the position of the terminal. The N measurements are measurements of PRS resource 2 transmitted at N different times. By the method, the RSTD measurement accuracy is improved, and the positioning accuracy can be improved.

In another implementation, the positioning server does not indicate smooth information of the positioning measurement to the terminal. The terminal may request the smooth information of the positioning measurement quantity from the positioning server according to the accuracy of the measurement result, and the positioning server indicates the smooth information of the positioning measurement quantity to the terminal according to the request.

In another implementation, the positioning server does not indicate smooth information of the positioning measurement to the terminal. The terminal determines the smooth information of the positioning measurement quantity by itself, and the terminal can report the smooth information determined by itself to the positioning server.

In addition, when the terminal reports, each positioning measurement quantity can be associated with a plurality of time stamps, and the smooth measurement values corresponding to a plurality of different measurement times.

In addition, the positioning server may also configure corresponding smoothing parameters for each positioning measurement in the smoothing information of the positioning measurement. For example, a smoothing number, smoothing filter coefficient, etc. are configured for the positioning measurement RSTD; another smoothing number, smoothing filter coefficients, etc. are configured for the positioning measurement RSRP.

Example 2:

for uplink positioning, a service network device of the terminal configures q=16 SRS resources for the terminal, and each SRS resource is shaped differently and points to different directions. The positioning server configures each of the p=3 network devices (denoted as network device 0, network device 1 and network device 2) for positioning the terminal to report an angle measurement quantity, which includes A-AoA and Z-AoA. The positioning server configures the q=16 SRS resources to the 3 network devices, and indicates smooth information of the positioning measurement quantity to the 3 network devices. The smoothing information of the positioning measurement quantity includes a smoothing indication parameter, which indicates ON. The smoothing information of the positioning measurement quantity may further include a smoothing number N, which indicates that a result of using the N measurements is smoothed to obtain a smoothed measurement value. Further, smoothing filter coefficients may be included in the smoothing information of the positioning measurement quantity.

The serving network device of the terminal measures the horizontal dimension angle and the vertical dimension angle of each of the q=16 SRS resources. According to the configuration of the positioning server, the smoothed measurement values of the horizontal dimension angle and the vertical dimension angle are smoothed results of angle measurement values of N times of measurement, and are as follows:

smooth measured values of A-AoA = a (0) A-AoA _0+a (1) A-AoA _1+ … +a (N-1) A-AoA _ (N-1)

Where A-AoA _0, A-AoA _1, …, A-AoA _ (N-1) are horizontal dimensional angle measurements of different times for one SRS resource, and (a (0), a (1), …, a (N-1)) are smoothing filter coefficients. The smoothed measurement of the vertical dimension angle Z-AoA is similar to A-AoA and will not be described in detail herein. The service network device of the terminal reports the smooth measurement values of the horizontal dimension angle and the vertical dimension angle of each resource of q=16 SRS resources to the positioning server. Similarly, each other network device also measures the smoothed measured values of the smoothed horizontal dimension angle and the smoothed vertical dimension angle, and reports the smoothed measured values to the positioning server. And after the positioning server receives the reporting of the angle measurement quantity of each network device, the positioning server performs position calculation of the terminal and determines the position of the terminal.

In another implementation, the positioning server does not indicate smooth information of the positioning measurements to the network device. Any one or more of the network device 0, the network device 1, and the network device 2 may request the measurement quantity smoothing information from the positioning server according to the accuracy of the measurement result, and according to the request, the positioning server indicates the smoothing information of the positioning measurement quantity to the network device 0, the network device 1, and the network device 2.

In another implementation, the positioning server does not indicate smooth information of the positioning measurements to the network device. The network device determines the smooth information of the positioning measurement by itself, and at the same time, the network device can report the smooth information determined by itself to the positioning server.

Example 3:

fig. 3 is a schematic diagram of a direct communication link positioning scheme according to an embodiment of the present application, as shown in fig. 3, a target terminal sends SL-PRS auxiliary information to a vehicle 2/3/4 through radio resource control (Radio Resource Control, RRC) signaling. The SL-PRS auxiliary information comprises SL-PRS configuration information and reported measurement quantity information, such as reported AoA and receiving-transmitting time difference. The reported measurement quantity information includes smoothing information of the positioning measurement quantity, such as a smoothing indication parameter, which indicates ON. The smoothing information of the positioning measurement quantity may further include a smoothing number N, which indicates that a result of using the N measurements is smoothed to obtain a smoothed measurement value. Further, smoothing filter coefficients may be included in the smoothing information of the positioning measurement quantity.

The target terminal sends a first trigger signaling to trigger the vehicle 2/3/4 to send SL-PRS. When the target terminal receives the SL-PRS transmitted by the vehicle 2/3/4, a smoothed measurement value of the angle of arrival AoA of each SL-PRS, denoted aoa_r, is determined, and the smoothed measurement value is obtained by smoothing N times of angle measurement values according to the smoothed information of the positioning measurement values. Meanwhile, the target terminal sends a second trigger signaling to the vehicle 2/3/4 to indicate the SL-PRS sending time of the target terminal, the target terminal sends the SL-PRS, the vehicle 2/3/4 receives the SL-PRS and respectively determines a smooth measurement value of an arrival angle AoA of the SL-PRS, which is denoted as AoA_t, and the vehicle 2/3/4 obtains the smooth measurement value of the angle N times according to the smooth information of the positioning measurement value. Meanwhile, the vehicles 2/3/4 determine a smoothed measure of their time difference of transmitting and receiving SL-PRSs, denoted as T_rxtx, respectively. And the vehicle 2/3/4 feeds back the AoA_t and T_rxtx obtained by the smoothing calculation to the target terminal. While the target terminal determines a smoothed measure of the time difference in its transmission and reception SL-PRS, denoted t_txrx. And the target terminal calculates the distance and angle information between the vehicles according to the AoA_r, the AoA_t, the T_rxx and the T_txrx, so as to solve the relative position relationship between the target terminal and the vehicle 2/3/4, thereby realizing the relative positioning.

In another implementation, the target terminal does not indicate smooth information of the positioning measurement to the vehicle 2/3/4. One or more of the vehicles 2/3/4 may request the target terminal for the smooth information of the positioning measurement amount according to the accuracy of the measurement result, and the target terminal indicates the smooth information of the positioning measurement amount to the vehicle 2/3/4 according to the request. Alternatively, one or more of the vehicles 2/3/4 may autonomously determine the smoothing information of the positioning measurement, and the vehicle 2/3/4 may report the autonomously determined smoothing information to the target terminal.

The vehicle 2/3/4 may also receive or request from the location server smooth information of the location measurement configured by the location server when the target terminal and the vehicle are within network coverage.

Example 4:

the positioning server instructs the terminal to report the first smoothed measurement value. The first smoothed measurement value is an original measurement value based on DL-TDOA, UL-TDOA, multi-RTT, DL-AoD, UL-AoA, etc., and provides a corresponding smoothed measurement value, which may include, for example, RSTD, RTOA, terminal transceiving time difference, and network equipment transceiving time difference, RSRP, aoA, etc.

Based on the raw measurements of DL-TDOA, UL-TDOA, multi-RTT, DL-AoD, UL-AoA, etc., the smoother used to obtain the corresponding smoothed measurements may be expressed as follows:

y(k)＝f(y _m (k),y _m (k-1),y _m (k-2),…,y(k-1),y(k-2),…)

Where y (k) is at time t=t _k Reported smoothed measurement value of certain positioning measurement value after smoothing operation, y _m (k) At time t _k The raw measurement of the positioning measurement is obtained. f () is a smoothing function, depending on the smoothing algorithm. For example, using a time [ t ] _k ,t _k-1 ,…,t _k-M-1 ]The time t is obtained from the measured raw measurement value of the positioning measurement quantity _k The expression of the smoothing function f () used may be:

y(k)＝a ₀ y _m (k)+a ₁ y _m (k-1)+a ₂ y _m (k-2)+…+a _M-1 y _m (k-M+1)

wherein { a }, a ₀ ,a ₁ ,…,a _M-1 Is a smoother parameter, andin one embodiment, a ₀ ＝a ₁ ＝…＝a _M-1 ＝1/M。

In one embodiment, the smoothing function f () expression used may be:

y(k)＝w ₀ y _m (k)+(1-w _o )y(k-1)

in the formula, the smoother has only one weighting parameter w ₀ (0<w ₀ <1)。

Assuming that the positioning server requests the terminal to report the first smooth measured value of the RSTD, the terminal sends the first smooth measured value of the RSTD obtained through calculation to the positioning server, and the positioning server performs positioning.

In another embodiment, the positioning server instructs the terminal to report the second measurement of smoothness. The second smoothed measurement value is a raw measurement value based on DL-TDOA, UL-TDOA, multi-RTT, DL-AoD, UL-AoA, etc., and a carrier phase measurement value to provide a corresponding smoothed measurement value, which may also be referred to as a carrier phase smoothed measurement value, and the used smoother may be expressed as follows:

y(k)＝f(y _m (k),y _m (k-1),y _m (k-2),…,φ _m (k),φ _m (k-1),…,y(k-1),y(k-2),…)

Where y (k) is at time t=t _k Reported smoothed measurement value of certain positioning measurement value after smoothing operation, y _m (k) At time t _k The raw measurement value of the positioning measurement value phi obtained _m (k) At time t _k The carrier phase measurements obtained.

For example, using a time [ t ] _k ,t _k-1 ,…,t _k-M-1 ]The measured raw measurement of the positioning measurement quantity and the NR carrier phase measurement value are obtained to obtain a time t _k The expression of the smoothing function f () used may be:

y(k)＝a ₀ y _m (k)+a ₁ y _m (k-1)+a ₂ y _m (k-2)+…+a _M-1 y _m (k-M+1)+b ₀ φ _m (k)+b ₁ φ _m (k-1)+b ₂ φ _m (k-2)+…+b ₂ φ _m (k-M+1)

or,

y(k)＝a ₀ y _m (k)+a ₁ y _m (k-1)+a ₂ y _m (k-2)+…+a _M-1 y _m (k-M+1)+b ₀ g(φ _m (k))+b ₁ g(φ _m (k-1))+b ₂ g(φ _m (k-2))+…+b ₂ g(φ _m (k-M+1))

wherein { a }, a ₀ ,a ₁ ,…,a _M-1 Sum { b } ₀ ,b ₁ ,…b _M-1 And the value of each parameter is larger than 0 and smaller than 1, and g () is a transformation function.

In one embodiment, the expression of the smoothing function f () used may be:

y(k)＝w ₀ y _m (k)+(1-w _o )(y(k-1)+(φ _m (k)-φ _m (k-1))

or,

y(k)＝w ₀ y _m (k)+(1-w _o )(y(k-1)+g(φ _m (k)-φ _m (k-1)))

And if the positioning server requests the terminal to report the second smooth measured value of the RSTD, the terminal sends the second smooth measured value of the RSTD obtained through calculation to the positioning server, and the positioning server performs positioning.
