Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of an information reporting method provided in an embodiment of the present invention, and is applied to a network device, such as a base station. As shown in fig. 1, the method comprises the following steps:
step 101, acquiring a first reference signal.
Wherein the first reference signal comprises: at least one reference signal of C-SRS-Pos, PRACH, DMRS, and SRS.
The virtual wavelength is constructed by using phase measurement values measured by C-SRS-Pos transmitted by a plurality of carrier frequencies, so that the space searching speed of the whole-cycle ambiguity is accelerated.
And 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 the measurement method based on a pre-configured or its own policy. The first phase measurement includes at least one of an intra-cycle phase value (M), an integer ambiguity (A), and an integer phase value (N).
There is an uncertainty problem of integer periods, since the receiving side cannot directly measure the number of integer periods of the phase change experienced by the first reference signal on the propagation path through the first reference signal. Integer ambiguity refers to the number of indeterminate or ambiguous integer number of cycles that the receiving side cannot directly measure. The full-cycle phase value refers to the number of integer cycles of the phase change experienced by the first reference signal on the propagation path, which can be directly measured by the receiving side through the first reference signal. The intra-cycle phase value refers to the number of fractional cycles of a phase change experienced by the first reference signal on the propagation path, which can be directly measured by the receiving side through 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 obtained according to at least one of a whole-cycle ambiguity, a whole-cycle phase value, and an intra-cycle phase value.
Wherein the UL-RPOA is: a phase value of a starting time point of a subframe i containing the first reference signal received by the node j with respect to a configurable reference time point or a UL-RPOA reference time point.
Wherein the configurable reference time point is 1900 years, 1 month, 1 day, 0 hour, 0 minute and 0 second. The UL-RPOA reference time point is T0+ T _ SRS, T0 represents a time of a start position of a system radio frame numbered 0, and T _ SRS is (10n ═ SRS)f+nsf)×10-3Wherein n isfAnd nsfRespectively representing the system radio frame number of the subframe i containing the first reference signal and the subframe number in the system radio frame.
The UL-RSPD is as follows: the relative phase difference upstream between node j and reference node i. The UL-RSPD may be calculated as follows:
UL-RSPD ═ P (received subframe, node j) -P (received subframe, node i);
wherein P (receive subframe, node j) represents the phase of the starting time point of a subframe received by the network device from node j, and P (receive subframe, node i) represents the phase of the starting time point of the subframe received by the network device from node i, which is closest in time to the subframe received from node j;
wherein the measurement reference point of the UL-RPOA or the UL-RSPD is a receiving antenna, a receiving antenna connector, or a receiving transceiver array boundary connector of a network device.
The node j comprises a terminal to be positioned, and the node i comprises a reference terminal, a reference base station, a reference cell or a reference TRP. In practical applications, 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, the rectangles in the figure represent the received subframes a from UE i, respectively, and the line 21 in the figure represents the reference time point. Thus, the phase difference between the subframe start time point of the reception subframe a and the reference time point is UL-RPOA. And the small block 22 represents SRS-Pos resources used to determine the starting point in time of one subframe for UE i or UE j.
As shown in fig. 3, two rectangles in the figure represent the received subframe from UE i and the received subframe from UE j, respectively, and the received subframe B is the closest subframe in time between the received subframe a received by UE i and all the subframes received by 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. And the small blocks 31 and 32 represent SRS-Pos resources, respectively, which are used to determine a starting time point of one subframe of UE i or UE j.
Wherein the unit of the first phase measurement is a first unit of time or radians. The first time unit is G times a second time unit, wherein G is a positive number, and the second time unit is a second, millisecond, microsecond or nanosecond.
In the embodiment of the present invention, the calculation method of the first phase measurement amount may be determined according to the content of the first phase measurement amount.
One, if the first phase measurement comprises an integer ambiguity:
(1) the unit of the first phase measurement is a first unit of time:

where u is a configurable adjustment coefficient, and its 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 very high (e.g., FR2), the intra-cycle phase value M (i.e., the fractional part) in the first phase measurement can be ignored, and only the integer ambiguity and the integer phase value can be reported, so as to reduce the reporting overhead.
It should be noted that, according to the formula POA + N + M for the first phase measurement, a is the integer ambiguity and is an unknown quantity for the base station, that is, the base station does not know how many integer cycles have passed compared with the reference time point after receiving the uplink positioning reference signal, so there is ambiguity problem.

For example, as shown in fig. 7, it is assumed that a gNB1 is a serving base station of a UE1, a gNB2 is a neighbor base station of the UE1, and the gNB1 and the gNB2 respectively receive uplink positioning reference signals SRS-Pos1 and SRS-Pos2 transmitted by the UE 1. Assuming that gNB1 calculated from SRS-Pos1 measurements from UE1 yields N1-51 nsec, M1-0.28 nsec, gNB2 calculated from SRS-Pos2 measurements from UE1 yields N2-72 nsec, and M2-0.65 nsec, then:

After the first phase measurement quantity is reported, the distance value is obtained without multiplying the first phase measurement quantity by the carrier wavelength, but the distance value can be obtained by directly multiplying the first phase measurement quantity by the light speed, the phase value is consistent for different carrier wavelengths, and the resolution is also consistent.
In an embodiment of the present invention, the unit of the first phase measurement is radian, which includes a full-cycle phase value and an intra-cycle phase value.
When the first phase measurement is in radian, the whole-cycle phase value N in the first phase measurement is an integral multiple part of 2 pi of the phase measurement value in the first phase measurement; when the first phase measurement is in radians, the intra-cycle phase value M in the first phase measurement is a fractional multiple of 2 pi of the phase measurement in the first phase measurement.
The calculation method of the first phase measurement quantity comprises the following steps:
when the first phase measurement is in radians, POA ═ N + M × 2 pi;
where N is the whole-cycle phase value and M is the intra-cycle phase value.
If the carrier frequency is very high (e.g. FR2), the intra-cycle phase value M (i.e. the fractional part) in the first measurement quantity can be ignored, and only the whole-cycle phase value can be reported, so as to reduce the reporting overhead.
Note that, the calculation formula POA of the first phase measurement amount is (N + M) × 2 pi. The whole-cycle phase value N is a whole-cycle phase value that can be obtained by the base station through measurement, is a known quantity to the base station, is an integral multiple part of 2 pi in the phase value that can be obtained through measurement, and is also an integral multiple part of 2 pi in the phase measurement value in the first phase measurement quantity.

For example, as shown in fig. 8, it is assumed that a gNB1 is a serving base station of a UE1, a gNB2 is a neighbor base station of the UE1, and a gNB1 and a gNB2 are uplink positioning reference signals SRS-Pos1 and SRS-Pos2 transmitted by a UE1, respectively. Assuming that gNB1 calculated from SRS-Pos1 measurements from UE1 yields N1-89 and M1-0.35, and gNB2 calculated from SRS-Pos2 measurements from UE1 yields N2-96 and M2-0.86, then:
the values of the first phase measurement obtained from SRS-Pos1 are:
POA1 ═ N + M × 2 pi ═ 89+0.35 × 2 pi ═ 89.35 × 2 pi (radians)
The values of the first phase measurement obtained from SRS-Pos2 are:
POA1 ═ N + M × 2 pi ═ 96+0.86 × 2 pi ═ 96.86 × 2 pi (radians)
If the positioning scheme is based on a base station (gNB-based), the gNB1 or gNB2 may calculate values of the first phase measurement quantities for SRS-Pos1 and SRS-Pos2 according to the above formula, thereby completing the UE position solution.
If the positioning scheme is a base station-assisted (gNB-assisted) positioning scheme, the gNB1 reports the measured values of N1-89 and M1-0.35 obtained from SRS-Pos1, and N2-96 and M2-0.86 obtained from SRS-Pos2 to the gNB1 or LMF, and the gNB or LMF performs further UE position resolution according to the above formula.
In the embodiment of the present invention, the first phase measurement includes two items of information, i.e., a whole-cycle phase value and an intra-cycle phase value, and the unit is radian. The phase value of the whole circle is integral multiple of 2 pi, which is integral multiple of the phase in one wavelength in real physical sense.
In an embodiment of the invention, the following resolution may also be calculated:
resolution of integer ambiguity: reported resolution R of whole-cycle phase valueAComprises the following steps:
Figure BDA0002491467610000231
wherein k isAIs 0 or a positive integer, the value of which is configurable, kAThe smaller the value, the higher the resolution.
Resolution of whole-cycle phase values: reported resolution R of whole-cycle phase valueNComprises the following steps:
Figure BDA0002491467610000232
wherein k isNIs 0 or a positive integer, the value of which is configurable, kNThe smaller the value, the higher the resolution.
Resolution of intra-cycle phase values: the intra-cycle phase values have a different resolution than the full-cycle phase values. Reported resolution R of phase value in cycleMComprises the following steps:
Figure BDA0002491467610000233
wherein k isMIs 0 or a positive integer, the value of which is configurable, kMThe larger the value, the higher the resolution.
In specific application, the resolution k can be configured according to at least one item of information such as carrier working frequency, carrier bandwidth, SCS, indoor or outdoor, positioning accuracy requirement and the likeNOr kMTo meet the positioning accuracy requirement.
For example: if the system positioning accuracy requirement is centimeter level, the positioning distance resolution is required to be 1 centimeter. If the system configuration requires that, when the first phase measurement consists of a full cycle phase value and an intra-cycle phase value, and the first time unit is nanoseconds, 1 nanosecond corresponds to 0.3 meters.
Suppose a system configuration kAWhen 0, the resolution of the whole-cycle phase value is:
Figure BDA0002491467610000234
i.e. the time resolution of the whole-cycle phase values is 1 nanosecond, the corresponding range resolution is 0.3 meters.
Suppose a system configuration kMThen the resolution of the intra-cycle phase values is:
Figure BDA0002491467610000241
i.e., the temporal resolution of the phase values in the week is 1/32 nanoseconds, corresponding to a range resolution of about 0.01 meters.
It can thus be seen that the resolution of the first phase measurement, consisting of the whole-cycle phase value and the intra-cycle phase value, can be on the order of 1 cm.
In the embodiment of the invention, each first phase measurement quantity can correspond to measurement quality indication information. The measurement quality indication information of the first phase measurement quantity comprises: error value EVError resolution ERAnd the number of error sampling points ENAnd/or the like. Wherein the error value ERMeans an optimal estimate of the uncertainty of the measured value; error resolution ERIs the error value EVThe quantization step size of the indicated domain; number of error sampling points ENRefers to calculating an error value EVThe number of measurements used.
Each first phase measurement may correspond to measurement confidence level information. Confidence level Y refers to: error value E of the first phase measurementVIn a confidence interval [ Xmin,Xmax]I.e.:
Y=Prob{Xmin≤EV≤Xmax}
wherein, Xmin,XmaxAre all greater than 0 for configuration information.
For example, when the unit of the first phase measurement is nanosecond, the error value EVWith 5 bits instead, different bit sequences representing different error values, and error resolution ERSelected by UE from {0.01m, 0.1m, 1m, 10m } setReporting to meet different indoor or outdoor positioning accuracy requirements. Number of error sampling points ENThe number of sampling points used by the UE for error measurement may be set to 1000, for example.
And when the system configures a confidence interval [ X ]min,Xmax]Is [0 cm, 5 cm ]]If the first phase measurement has 1000 error values EV950 error values are in the interval 0 cm, 5 cm]When, the confidence level Y is 95%. The base station can measure and report the confidence level so that the LMF and the like can evaluate the measurement quality of the phase measurement quantity.
When the base station reports, there may be the following two reporting modes:
(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) through the first phase measurement, if the phase measurement is configured, the delay measurement will not be reported.
(2) And 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 correlation or corresponding relation between the first phase measurement quantity and the time delay measurement quantity, thereby facilitating the measurement quantity combination at the receiving side.
In particular, since a plurality of positioning methods can be simultaneously configured and used, such as a positioning method based on time measurement and a positioning method based on phase measurement; meanwhile, in order to support a plurality Of positioning methods, a plurality Of positioning measurement quantities are also configured at the same time, such as a delay measurement quantity (TOA or TDOA) and a Phase measurement quantity (POA (Phase Of Arrival) or PDOA (Phase Difference Of Arrival)). Because the phase measurement is more accurate and has higher precision, and the time delay measurement can be calculated from the phase measurement, the time delay measurement can not be reported any more if the phase measurement is configured.
In addition, considering that if the base station reports the delay measurement and the first phase measurement simultaneously, the reliability of positioning can be improved, and the positioning delay is reduced, the system can also configure the base station to report the phase measurement and the delay measurement simultaneously. In this case, in order to combine the measurement quantities at the receiving side, the base station reports the correlation between the phase measurement quantity and the delay measurement quantity at the same time when reporting the measurement quantities.
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 at the same time and also reports the incidence relation between the phase measurement quantity and the time delay measurement quantity, so that the signaling overhead of reporting can be reduced, or the positioning accuracy is improved.
It can be seen from the above description that, by adopting the scheme of the embodiment of the present invention, a more accurate position of the terminal can be calculated through the reported information of the whole cycle phase value and the cycle phase value of the phase measurement, and the like, thereby avoiding the terminal positioning position deviation caused by insufficient accuracy of the time delay measurement in the prior art, and further improving the system positioning accuracy.
