According to the UL-TDOA time delay positioning method, the position of a terminal is estimated through the relative time difference (Uplink-Relative Time Of Arrival, UL-RTOA, uplink relative arrival time) between the arrival time of SRS-Pos (Sounding Reference Signal for Positioning, a sounding reference signal for positioning) and the reference time of the base station itself according to the difference of the propagation distances of the terminal relative to each base station. The UL-AOA angle positioning method determines the position of the terminal through a plurality of angle parameters according to the position direction of the terminal relative to the base station.

However, the system positioning accuracy of the existing positioning method is low.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart of an information reporting method provided in an embodiment of the present invention, which is applied to a network device, such as a base station. As shown in fig. 1, the method comprises the following steps:

Step 101, a first reference signal is acquired.

Wherein the first reference signal comprises: C-SRS-Pos, SRS-Pos, PRACH, DMRS, and SRS.

The method comprises the steps of constructing a virtual wavelength by using phase measurement values measured by C-SRS-Pos transmitted by a plurality of carrier frequencies, thereby accelerating the space searching speed of the whole-cycle ambiguity.

Step 102, measuring according to the first reference signal to obtain a first phase measurement quantity.

In the embodiment of the present invention, the measurement method of the first phase measurement amount is not limited. The network device may select a measurement method based on a pre-configured or own policy. The first phase measurement includes at least one of an intra-cycle phase value (M), a whole-cycle ambiguity (a), and a whole-cycle phase value (N).

Wherein, the receiving side cannot directly measure the number of integer periods of the phase change undergone by the first reference signal on the propagation path through the first reference signal, so that the problem of uncertainty of the integer periods exists. Integer ambiguity refers to the number of indeterminate or ambiguous integer periods that the receiving side cannot directly measure. The whole-cycle phase value refers to the number of integer cycles of the phase change undergone by the first reference signal on the propagation path by the receiving side, which can be directly measured by the first reference signal. The intra-cycle phase value refers to the number of fractional periods of the phase change undergone by the first reference signal on the propagation path, which the receiving side can directly measure by the first reference signal.

In practical applications, the first phase measurement is UL-POA, UL-RPOA or UL-RSPD, wherein the UL-POA, UL-RPOA or UL-RSPD is derived from at least one of a whole-cycle ambiguity, a whole-cycle phase value, and a intra-cycle phase value.

Wherein, the UL-RPOA is: the phase value of the starting time point of subframe i, which is received by node j, containing the first reference signal, is compared to a configurable reference time point or UL-RPOA reference time point.

Wherein the configurable reference time point is 1900 1 month, 1 day, 0 hour, 0 minutes, 0 seconds. The UL-RPOA reference time point is t0+t_srs, T0 represents the time of the starting position of the system radio frame numbered 0, t_srs= (10 n) _f +n _sf )×10 ^-3 Wherein n is _f And n _sf The system radio frame number of the subframe i containing the first reference signal and the subframe number within the system radio frame are respectively indicated.

The UL-RSPD is: upstream relative phase difference between node j and reference node i. The UL-RSPD may be calculated as follows:

UL-rspd=p (receive subframe, node j) -P (receive subframe, node i);

Wherein node j comprises a terminal to be located and node i comprises a reference terminal, a reference base station, a reference cell or a reference TRP. In practical application, a starting time point of a subframe from the node i or the node j is determined according to at least one first reference signal resource. The first reference signal resource may include: C-SRS-Pos resources, PRACH resources, DMRS resources, SRS resources, and the like.

As shown in fig. 2, rectangles in the figure represent the received subframes a from UE i, respectively, and line 21 in the figure represents a reference time point. Thus, the phase difference between the subframe start time point of the received subframe a and the reference time point is UL-RPOA. While the small box 22 represents SRS-Pos resources used to determine the starting point in time of one subframe of UE i or UE j.

As shown in fig. 3, two rectangles in the figure represent a received subframe from UE i and a received subframe from UE j, respectively, and received subframe B is a closest in time subframe among a received subframe a received by UE from UE i and all subframes received from UE j. Thus, the phase difference between the subframe start time point of the reception subframe a and the subframe start time point of the reception subframe B is UL-RSPD. While

squares

31 and 32 represent SRS-Pos resources used to determine the starting point in time of one subframe of UE i or UE j, respectively.

Wherein the unit of the first phase measurement is a first time unit or radian. The first time unit is G times of a second time unit, wherein G is a positive number, and the second time unit is seconds, milliseconds, microseconds or nanoseconds.

In the embodiment of the present invention, the calculation mode of the first phase measurement amount may be determined according to the content included in the first phase measurement amount.

1. If the first phase measurement includes integer ambiguity:

(1) The unit of the first phase measurement amount is a first time unit:

in this case, the whole-cycle phase value is an integer part of a first time unit of the remaining phase measurement value part of the first phase measurement amount.

(2) The unit of the first phase measurement is radian:

In this case, the intra-cycle phase value is a fraction of 2pi of the phase measurement value of the first phase measurement amount.

Specifically, if the unit of the first phase measurement amount is a first time unit, the first phase measurement amount may be calculated in different manners according to different contents included in the first phase measurement amount.

poa=u×a+n+m; or alternatively

POA＝A+N+M。

poa=u×a+m; or alternatively

POA＝A+M。

POA＝N+M。

specifically, if the unit of the first phase measurement amount is an arc, the first phase measurement amount may be calculated in different manners according to different contents included in the first phase measurement amount.

poa= (u×a+n+m) ×2pi; or alternatively

POA＝(A+N+M)×2π。

poa= (u×a+m) ×2pi; or alternatively

POA＝(A+M)×2π。

POA＝(N+M)×2π。

in the above formula, POA represents the first phase measurement amount; u represents an adjustment coefficient, which is an integer greater than or equal to 0; a represents integer ambiguity; n represents the whole cycle phase value; m represents the intra-week phase value.

Wherein, the report resolution ratio R of the whole cycle ambiguity _A The method comprises the following steps:

wherein k is _A Is 0 or a positive integer, the value of which is configurable, k _A The smaller the value, the higher the resolution.

Wherein, the report resolution ratio R of the whole cycle phase value _N The method comprises the following steps:

In addition, can also rootThe resolution k is configured according to at least one information of carrier working frequency, carrier bandwidth, SCS (Sub Carrier Spacing, subcarrier interval), indoor or outdoor, positioning accuracy requirement and the like _N Or k _M To meet the positioning accuracy requirement.

Step 103, reporting the first phase measurement quantity.

In practice, the base station may report the first phase measurement to an LMF (Location Management Function ), LMC (Location Management Center, location management center) or other location processing unit.

Referring to fig. 4, fig. 4 is a flowchart of an information reporting method provided by an embodiment of the present invention, which is applied to a location management device. The location management device may be an LMF, LMC or other location processing unit. As shown in fig. 4, the method comprises the following steps:

Step 401, receiving a first phase measurement.

Wherein the first phase measurement includes at least one of an intra-cycle phase value, a whole-cycle ambiguity, and a whole-cycle phase value. The meaning of each information in the first phase measurement amount can be referred to the description of the foregoing embodiment.

And step 402, performing position calculation of the terminal according to the first phase measurement quantity.

Wherein, on the basis of the above embodiment, the positioning management device may further receive at least one of measurement quality indication information and measurement confidence level information.

If the network device reports the time delay measurement quantity, the positioning management device can also receive the time delay measurement quantity and the relation between the first phase measurement quantity and the time delay measurement quantity, so that the position calculation of the terminal is facilitated. If the network equipment does not report the time delay measurement quantity, the positioning management equipment can also obtain the time delay measurement quantity according to the first phase measurement quantity, so that the position calculation of the terminal is facilitated.

In an embodiment of the invention, the first phase measurement is in nanoseconds, including integer ambiguity, integer phase values, and intra-week phase values.

Wherein, integer ambiguity A in the first phase measurement: i.e. the integer ambiguity part in the first phase measurement.

When the first phase measurement amount is in units of nanoseconds, the whole-cycle phase value N in the first phase measurement amount is an integer part of nanoseconds of the remaining phase measurement value portion excluding the whole-cycle ambiguity in the first phase measurement amount.

When the first phase measurement amount is in nanoseconds, the intra-cycle phase value M in the first phase measurement amount is a fraction of nanoseconds of the remaining phase measurement value portion excluding the integer ambiguity in the first phase measurement amount.

The calculation method of the first phase measurement quantity is as follows:

poa=u×a+n+m when the first phase measurement amount is in nanoseconds;

where u is a configurable adjustment coefficient, whose value is 0 or a positive integer, A is the integer ambiguity, N is the integer phase value, and M is the intra-cycle phase value.

If the carrier frequency is high (e.g., FR 2), the intra-cycle phase value M (i.e., the fractional portion) in the first phase measurement may be ignored, and only the integer ambiguity and the integer phase value may be reported, so as to reduce reporting overhead.

It should be noted that, according to the calculation formula poa=u×a+n+m of the first phase measurement quantity, a is a whole-cycle ambiguity, and a is an unknown quantity to the base station, that is, the base station does not know how many whole cycles have elapsed compared with the reference time point after receiving the uplink positioning reference signal, so there is an ambiguity problem. The integer ambiguity a cannot be obtained by measurement but by spatial search, the integer ambiguity a being an integer number of nanoseconds. The whole-cycle phase value N is a whole-cycle phase value that can be obtained by the base station by measuring, is a known quantity to the base station, is an integer part of nanoseconds in the phase value that can be obtained by measuring, and is an integer part of nanoseconds in the remaining phase measurement value part excluding the whole-cycle ambiguity in the first phase measurement quantity. The intra-cycle phase value M is a intra-cycle phase value that can be obtained by the base station by measuring, a known quantity to the base station, a fraction of nanoseconds in the phase value that can be obtained by measuring, and a fraction of nanoseconds in the remaining phase measurement value portion excluding the integer ambiguity in the first phase measurement quantity. The whole-cycle phase value N + the intra-cycle phase value M together constitute a phase value known to the base station.

For example, as shown in fig. 5, it is assumed that gNB1 is a serving base station of UE1, gNB2 is a neighboring base station of UE1, and gNB1 and gNB2 receive uplink positioning reference signals SRS-Pos1 and SRS-Pos2 sent by UE1, respectively. The adjustment coefficient u is configured to be 1, and assuming that gNB1 calculates the integer ambiguity a1=923 ns, n1=51 ns, m1=0.28 ns from SRS-Pos1 measurements from UE1, gNB2 calculates the integer ambiguity a2=1265 ns, n2=72 ns, m2=0.65 ns from SRS-Pos2 measurements from UE1, then:

the value of the first phase measurement quantity obtained from SRS-Pos1 is: poa1=u+a1+n1+m1=1+923+51+0.28= 974.28 (nanoseconds)

The value of the first phase measurement quantity obtained from SRS-Pos2 is: poa2=u+a2+n2+m2=1×1265+72+0.65= 1337.65 (nanoseconds)

If the positioning scheme is based on the base station (gNB-based), gNB1 or gNB2 can calculate the values of the first phase measurement quantities for the SRS-Pos1 and the SRS-Pos2 according to the above formula, and then UE position calculation is completed.

In the case of a base station assisted (gNB-assisted) positioning scheme, gNB1 would report a1=923 nanoseconds, n1=51 nanoseconds, m1=0.28 nanoseconds, obtained from SRS-Pos1, and gNB would report a2=1265 nanoseconds, n2=72 nanoseconds, m2=0.65 nanoseconds, and other measurements obtained from SRS-Pos2 to the LMF, which would make further UE position solutions according to the above equation.

In the embodiment of the invention, the first phase measurement quantity comprises three pieces of information including integer ambiguity, integer phase value and intra-week phase value, and the unit of the first phase measurement quantity is nanosecond. After the first phase measurement quantity is reported, the distance value is obtained by directly multiplying the first phase measurement quantity by the light speed instead of the carrier wave wavelength, the distance value is obtained by directly multiplying the first phase measurement quantity by the light speed, the phase value is consistent for different carrier wave wavelengths, and the resolution is consistent, so that the speed and the efficiency of the position calculation of the UE are improved, and the positioning precision of the system is also improved.

In an embodiment of the present invention, the first phase measurement is in radians including integer ambiguity, integer phase values, and intra-cycle phase values.

Wherein, integer ambiguity A in the first phase measurement: i.e. the integer ambiguity fraction in the first phase measurement; when the first phase measurement amount is in radians, the whole-cycle phase value N in the first phase measurement amount is an integer multiple part of 2pi of the remaining phase measurement value part excluding the whole-cycle ambiguity in the first phase measurement amount; when the first phase measurement amount is in radians, the intra-cycle phase value M in the first phase measurement amount is a fraction of 2pi of the remaining phase measurement value portion excluding the integer ambiguity in the first phase measurement amount.

The calculation method of the first phase measurement quantity is as follows:

when the first phase measurement amount is in radians, poa= (u×a+n+m) ×2pi;

If the carrier frequency is high (e.g., FR 2), the intra-cycle phase value M (i.e., the fractional portion) in the first measurement may be ignored, and only the integer ambiguity and the integer phase value may be reported, so as to reduce reporting overhead.

It should be noted that, according to the calculation formula poa= (u×a+n+m) ×2pi of the first phase measurement amount, the whole-cycle ambiguity a is a whole-cycle ambiguity, and is an unknown quantity to the base station, that is, the base station does not know how many whole cycles have elapsed compared with the reference time point after receiving the uplink positioning reference signal, so there is a problem of ambiguity. The integer ambiguity a cannot be obtained by measurement but by spatial search, the integer ambiguity a being an integer number 2 pi. The whole-cycle phase value N is the whole-cycle phase value that the base station can obtain by measuring, is a known quantity to the base station, is an integer multiple of 2pi in the phase values that can be obtained by measuring, and is an integer multiple of 2pi in the remaining phase measurement value portion excluding the whole-cycle ambiguity in the first phase measurement quantity. The intra-cycle phase value M is a fraction of 2pi of the phase values that the base station can obtain by measuring, and is a fraction of 2pi of the remaining phase measurement values excluding the integer ambiguity in the first phase measurement amount, which is a known quantity to the base station. The whole-cycle phase value N + the intra-cycle phase value M together constitute a phase value known to the base station.

For example, as shown in fig. 6, it is assumed that gNB1 is a serving base station of UE1, gNB2 is a neighboring base station of UE1, and gNB1 and gNB2 receive transmitted uplink positioning reference signals SRS-Pos1 and SRS-Pos2 of UE1, respectively. The adjustment coefficient u is configured to be 1, and assuming that gNB1 calculates integer ambiguity a1=4032, n1=89, m1=0.35, and gNB2 calculates integer ambiguity a2=3876, n2=96, m2=0.86, based on SRS-Pos1 measurement from UE1, then:

the value of the first phase measurement quantity obtained from SRS-Pos1 is:

POA1＝(u*A+N+M)×2π＝(1*4032+89+0.35)×2π

= 4121.35 ×2pi (radian)

The value of the first phase measurement quantity obtained from SRS-Pos2 is:

POA1＝(u*A+N+M)×2π＝(1*3876+96+0.86)×2π

= 3972.86 ×2pi (radian)

In the case of a base station assisted (gNB-assisted) positioning scheme, gNB1 reports the measurements a1=4032, n1=89, m1=0.35, obtained from SRS-Pos1, and gNB2 reports the measurements a2=3876, n2=96, m2=0.86, obtained from SRS-Pos2, to the LMF, which performs further UE position calculation according to the above equation.

In the embodiment of the invention, the first phase measurement quantity comprises three pieces of information including whole-cycle ambiguity, whole-cycle phase value and intra-cycle phase value, and the unit of the first phase measurement quantity is radian. The integer ambiguity and the integer phase value are integer multiples of 2 pi, which is an integer multiple of the phase within one wavelength in a real physical sense.

In an embodiment of the invention, the first phase measurement is in nanoseconds, which includes a full cycle phase value and a intra-cycle phase value.

When the first phase measurement amount is in units of nanoseconds, the entire-cycle phase value N in the first phase measurement amount is an integer part of nanoseconds of the phase measurement value in the first phase measurement amount;

when the first phase measurement amount is in nanoseconds, the intra-cycle phase value M in the first phase measurement amount is a fraction of nanoseconds of the phase measurement value in the first phase measurement amount;

the calculation method of the first phase measurement quantity is as follows:

when the first phase measurement amount is in nanoseconds, poa=n+m;

where N is the whole circumference phase value and M is the intra-circumference phase value.

If the carrier frequency is high (e.g., FR 2), the intra-week phase value M (i.e., the fractional portion) in the first measurement may be ignored, and only the entire-week phase value may be reported, so as to reduce reporting overhead.

Note that, according to the calculation formula poa=n+m of the first phase measurement amount, the whole-cycle phase value N is a whole-cycle phase value that can be obtained by the base station by measurement, is a known amount to the base station, and is an integer part of nanoseconds among the phase values that can be obtained by measurement, and is also an integer part of nanoseconds of the phase measurement value in the first phase measurement amount. The intra-week phase value M is a phase value within the week that the base station can obtain by measuring, a known quantity to the base station, a fraction of nanoseconds in the phase value that can be obtained by measuring, and a fraction of nanoseconds in the phase measurement value in the first phase measurement quantity. The whole-cycle phase value N + whole-cycle phase value M together constitute a phase value known to the base station.

For example, as shown in fig. 7, it is assumed that gNB1 is a serving base station of UE1, gNB2 is a neighboring base station of UE1, and gNB1 and gNB2 respectively receive uplink positioning reference signals SRS-Pos1 and SRS-Pos2 sent by UE 1. Assuming that gNB1 calculates n1=51 nanoseconds from SRS-Pos1 measurements from UE1, m1=0.28 nanoseconds, gNB2 calculates n2=72 nanoseconds from SRS-Pos2 measurements from UE1, m2=0.65 nanoseconds:

the value of the first phase measurement quantity obtained from SRS-Pos1 is:

Poa1=n1+m1=51+0.28= 51.28 (nanoseconds)

The value of the first phase measurement quantity obtained from SRS-Pos2 is:

poa2=n2+m2=72+0.65= 72.65 (nanoseconds)

In the case of a base station assisted (gNB-assisted) positioning scheme, gNB1 would report the measurement values of n1=51 ns, m1=0.28 ns, and gNB2 would report the measurement values of n2=72 ns, m2=0.65 ns, etc. obtained from SRS-Pos1 to the LMF, which would make further UE position solutions according to the above equation.

In the embodiment of the present invention, the first phase measurement amount includes two pieces of information of the whole-cycle phase value and the intra-cycle phase value, and the unit thereof is nanoseconds. After the first phase measurement quantity is reported, the distance value is obtained by directly multiplying the distance value with the light speed without multiplying the distance value with the carrier wave wavelength, the phase value is consistent for different carrier wave wavelengths, and the resolution is consistent.

In an embodiment of the invention, the first phase measurement is in radians comprising a full cycle phase value and a intra-cycle phase value.

When the first phase measurement amount is in radians, the whole-cycle phase value N in the first phase measurement amount is an integer multiple part of 2pi of the phase measurement value in the first phase measurement amount; when the first phase measurement amount is in radians, the intra-cycle phase value M in the first phase measurement amount is a fraction of 2pi of the phase measurement value in the first phase measurement amount.

The calculation method of the first phase measurement quantity is as follows:

when the first phase measurement amount is in radians, poa= (n+m) ×2pi;

Note that, according to the calculation formula poa= (n+m) ×2pi of the first phase measurement amount. The whole phase value N is the whole phase value that the base station can obtain by measuring, a known quantity to the base station, an integral multiple fraction of 2pi in the phase values that can be obtained by measuring, and an integral multiple fraction of 2pi in the phase measurement values in the first phase measurement quantity. The intra-week phase value M is a intra-week phase value that the base station can obtain by measuring, a known quantity to the base station, a fraction of 2pi in the phase values that can be obtained by measuring, and a fraction of 2pi in the phase measurement values in the first phase measurement quantity. The whole-cycle phase value N + whole-cycle phase value M together constitute a phase value known to the base station.

For example, as shown in fig. 8, it is assumed that gNB1 is a serving base station of UE1, gNB2 is a neighboring base station of UE1, and gNB1 and gNB2 are uplink positioning reference signals SRS-Pos1 and SRS-Pos2 transmitted by UE1, respectively. Assuming that gNB1 is calculated n1=89, m1=0.35 from SRS-Pos1 measurements from UE1, gNB2 is calculated n2=96, m2=0.86 from SRS-Pos2 measurements from UE1, then:

the value of the first phase measurement quantity obtained from SRS-Pos1 is:

poa1= (n+m) ×2pi= (89+0.35) ×2pi= 89.35 ×2pi (radian)

The value of the first phase measurement quantity obtained from SRS-Pos2 is:

poa1= (n+m) ×2pi= (96+0.86) ×2pi=96.86×2pi (radian)

In the case of a base station assisted (gNB-assisted) positioning scheme, gNB1 reports the measured values of n1=89, m1=0.35, n2=96, m2=0.86, and the like obtained from SRS-Pos1 to gNB1 or LMF, and the gNB or LMF performs further UE position calculation according to the above formula.

In the embodiment of the invention, the first phase measurement quantity comprises two pieces of information, namely a whole-cycle phase value and a cycle phase value, and the unit of the first phase measurement quantity is radian. The whole phase value is integral multiple of 2 pi and is integral multiple of the phase in one wavelength in the true physical sense.

In an embodiment of the present invention, the following resolutions may also be calculated:

resolution of integer ambiguity: reporting resolution R of whole cycle phase value _A The method comprises the following steps:

wherein k is _A Is 0 or a positive integer, the value of which is configurable, k _A The smaller the value, the more resolutionHigh.

Resolution of the whole cycle phase value: reporting resolution R of whole cycle phase value _N The method comprises the following steps:

Resolution of intra-week phase values: the intra-week phase value has a different resolution than the whole-week phase value. Report resolution R of intra-week phase values _M The method comprises the following steps:

In a specific application, the resolution k can be configured according to at least one item of information such as carrier operating frequency, carrier bandwidth, SCS, indoor or outdoor, positioning accuracy requirement, etc _N Or k _M To meet the positioning accuracy requirement.

By way of example: if the system positioning accuracy is required to be in the centimeter level, the positioning distance resolution is required to be 1 centimeter. If the system configuration requires that the first phase measurement consists of the whole cycle phase value and the intra-cycle phase value, and the first time unit is nanoseconds, 1 nanosecond corresponds to 0.3 meters.

Let it be assumed that the system configuration k _A =0, then the resolution of the full cycle phase value is:

that is, the time resolution of the whole-cycle phase value is 1 nanosecond, and the corresponding distance resolution is 0.3 meter.

Let it be assumed that the system configuration k _M =5, then the intra-week phase valueThe resolution of (2) is:

that is, the time resolution of the intra-week phase value is 1/32 nanoseconds, and the corresponding distance resolution is about 0.01 meters.

It can thus be seen that the resolution of the first phase measurement, which consists of the whole circumference phase value and the intra-circumference phase value, can be in the order of 1 cm.

In an embodiment of the present invention, each of the first phase measurement amounts may correspond to measurement quality indication information. The measurement quality indication information of the first phase measurement quantity comprises: error value E _V Error resolution E _R Number of error samples E _N And the like. Wherein the error value E _R The optimal estimated value of the measured value uncertainty is referred to; error resolution E _R Refers to the error value E _V Quantization step length of the indication domain; error sampling point number E _N Refers to calculating an error value E _V The number of measurements used.

Each first phase measurement may correspond to measurement confidence level information. Confidence level Y refers to: error value E of first phase measurement quantity _V Is within confidence interval [ X ] _min ,X _max ]Is, that is:

Y＝Prob{X _min ≤E _V ≤X _max }

wherein X is _min ，X _max Is configuration information, and is larger than 0.

For example, when the unit of the first phase measurement amount is nanoseconds, the error value E _V With 5 bits instead, different bit sequences represent different error values, and error resolution E _R The UE selects and reports the {0.01m,0.1m,1m,10m } set to meet different positioning precision requirements indoors or outdoors. Error sampling point number E _N Is the number of samples the UE uses for error measurement, and may be set to 1000, for example.

While when the system configures the confidence interval [ X ] _min ,X _max ]Is [0 cm, 5 cm ]]At the same time, if 1000 error values E of the first phase measurement quantity _V With 950 error values lying in the interval 0 cm, 5 cm]At this time, confidence level y=95%. The base station may measure and report the confidence level for the LMF or the like to evaluate the measurement quality of the current phase measurement.

When the base station reports, the following two reporting modes can be adopted:

(1) And the base station reports one of the first phase measurement quantity and the time delay measurement quantity.

Since the base station can calculate the corresponding TOA (Time Of Arrival) or TDOA (Time Difference Of Arrival ) from the first phase measurement amount, if the phase measurement amount is configured, the delay measurement amount will not be reported any more.

(2) The base station simultaneously reports the first phase measurement quantity and the time delay measurement quantity.

The base station reports the first phase measurement quantity and the time delay measurement quantity, and configures the association or corresponding relation between the first phase measurement quantity and the time delay measurement quantity, so that the measurement quantity combination at the receiving side is facilitated.

In particular, since a plurality of positioning methods can be configured and used simultaneously, such as a positioning method based on time measurement and a positioning method based on phase measurement; meanwhile, in order to support various positioning methods, various positioning measurement amounts such as a delay measurement amount (TOA or TDOA) and a Phase measurement amount (POA (Phase Of Arrival) or PDOA (Phase Difference Of Arrival )) are also configured at the same time. Since the phase measurement is more accurate and the delay measurement can be calculated from the phase measurement, if the phase measurement is configured, the delay measurement will not be reported.

In addition, considering that if the base station reports the delay measurement quantity and the first phase measurement quantity at the same time, the reliability of positioning can be improved, the positioning delay is reduced, and the system can also configure the base station to report the phase measurement quantity and the delay measurement quantity at the same time. In this case, in order to facilitate the measurement combining at the receiving side, the base station may report the association relationship between the phase measurement and the delay measurement at the same time when reporting the measurement.

The base station only reports one of the phase measurement quantity and the time delay measurement quantity, or the base station reports the time delay measurement quantity and the phase measurement quantity simultaneously, and also reports the association relationship between the phase measurement quantity and the time delay measurement quantity, so that the signaling overhead can be reduced, or the positioning accuracy can be improved.

According to the scheme provided by the embodiment of the invention, the more accurate position of the terminal can be calculated through the information reported by the whole-cycle phase value, the intra-cycle phase value and the like of the phase measurement quantity, so that the deviation of the positioning position of the terminal caused by the insufficient precision of the delay measurement quantity in the prior art is avoided, and the positioning precision of the system is improved.
