Description

Information transmission method, positioning processing method, device, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a positioning processing method, an apparatus, a terminal, and a network device.

Background

In the DL-AoD Positioning method, a terminal sends configuration information of a Positioning Reference Signal DL-PRS (Downlink Positioning Reference Signal) according to a peripheral TRP (Transmit and Receive Point) provided by an LMF (Location Management Function) unit to Receive the DL-PRS, measures each DL-PRS beam of each TRP, and reports a RSRP (Reference Signal Receiving Power) measurement value to the LMF unit. The LMF unit determines the angle of the terminal relative to each TRP, namely the downlink departure angle DL-AoD, by using RSRP reported by the terminal and other known information (such as the transmission direction of each DL-PRS beam of each TRP). Then, the location of the terminal is calculated using the obtained DL-AoD and the physical coordinates of each TRP.

In a DL-AoD positioning process, if the terminal orientation changes (e.g., rotates), the spatial relationship between the terminal receive beam Rx beam for receiving RSRP and the TRP transmit beam Tx beam for transmitting DL-PRS changes, and the RSRP measurement value no longer accurately reflects the spatial distribution of the DL PRS Tx beam power, resulting in an increased positioning error.

Detailed Description

The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

In the embodiments of the present application, the term "plurality" means two or more, and other terms are similar thereto.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.

First, it should be noted that in the prior art, if the terminal orientation changes (for example, rotates) during a DL-AoD positioning process, the spatial relationship between the terminal receiving beam Rx beam for receiving RSRP and the TRP transmitting beam Tx beam for transmitting DL-PRS changes accordingly; the inventors found that, even if the optimum Rx beam is determined at the beginning of the measurement due to the change of the terminal orientation, the reliability of DL-AoD estimated based on a set of RSRP values measured by the optimum Rx beam is lowered, and the positioning accuracy inevitably deteriorates. In the two methods, since the terminal orientation changes, the RSRP value of the same receiving antenna panel receiving the PRS signal also changes with the change of the terminal orientation, so the reliability of DL-AoD estimated based on the RSRP value is reduced, and the positioning accuracy inevitably deteriorates.

In order to solve the problem that the orientation of a terminal changes to cause an increase in positioning error, embodiments of the present application provide an information transmission method, a positioning processing method, an apparatus, a terminal, and a network device, where the method and the apparatus are based on the same application concept, and because the principles of solving the problem by the method and the apparatus are similar, the implementation of the apparatus and the method may be mutually referred to, and repeated parts are not described again.

As shown in fig. 1, a schematic flow chart of an information transmission method provided in an embodiment of the present invention is shown, where the method includes:

step 101: a terminal receives a positioning reference signal PRS sent by network equipment;

here, in the DL-AoD positioning method, the terminal may receive the PRS according to configuration information of a surrounding TRP provided by a network device (such as an LMF) to transmit the PRS.

Step 102: the terminal respectively executes Reference Signal Received Power (RSRP) measurement and downlink arrival angle (DL-AoA) measurement based on the PRS to obtain a first measurement result; and/or the terminal controls at least two antenna panels of the terminal to respectively measure specified measurement parameters based on the PRS to obtain a second measurement result;

in this step, reference signal received power RSRP measurement and downlink arrival angle DL-AoA measurement are respectively performed based on the PRS, which can be understood that when the terminal measures RSRP based on the PRS, the terminal simultaneously measures DL-AoA in the LCS coordinate system. That is to say, the positioning of the terminal not only refers to RSRP, but also adds a reference item, DL-AoA, which can reflect whether the terminal position changes, which is beneficial to improving the positioning accuracy.

Based on the PRS, at least two antenna panels of the terminal are controlled to respectively measure specified measurement parameters to obtain a second measurement result, and the measurement mode enables the terminal to report the measurement results of the specified measurement parameters respectively by the plurality of antenna panels instead of reporting the RSRP value measured by one antenna panel in the prior art, so that the network equipment can know whether the position of the terminal changes or not based on the measurement results, and the positioning accuracy is improved.

Step 103: and the terminal sends the first measurement result and/or the second measurement result to the network equipment.

According to the information transmission method, the positioning reference signal PRS sent by the network equipment is received through the terminal; respectively performing received power RSRP measurement and downlink arrival angle DL-AoA measurement based on the PRS to obtain a first measurement result; and/or controlling at least two antenna panels of the terminal to respectively measure specified measurement parameters based on the PRS to obtain a second measurement result; and sending the first measurement result and/or the second measurement result to the network equipment, so that the network equipment can determine whether the orientation of the terminal changes or not based on the measurement result obtained by the measurement mode through the measurement mode, and obtain the reliability of each RSRP measurement value, thereby being beneficial to improving the positioning accuracy.

As an optional implementation manner, in step 102 of the method according to the embodiment of the present invention, the terminal respectively performs reference signal received power RSRP measurement and downlink angle of arrival DL-AoA measurement based on the PRS, and obtains a first measurement result, including:

here, the first N first candidate RSRP measurement values in the order from large to small among the plurality of first candidate RSRP measurement values may be specifically selected as the first RSRP measurement value.

It should be noted that each first RSRP measurement value corresponds to a DL-AoA measurement value.

Here, specifically, the measurement result related to the DL-AoA measurement is obtained based on N DL-AoA measurement values corresponding to the N first RSRP measurement values, respectively.

Optionally, the measurement results relating to DL-AoA positioning measurements comprise at least one of:

a DL-AoA measurement value corresponding to each first RSRP measurement value;

here, the DL-AoA measurement value is obtained by the terminal measuring AoA of the downlink PRS according to its own LCS coordinate system. That is, the terminal measures the DL-AoA in the terminal LCS coordinate system based on the PRS, which is a directly obtained measurement result. Wherein each RSRP measurement value corresponds to one DL-AoA measurement value.

it should be noted that, at the terminal side, the possible numerical range of DL-AoA in the LCS coordinate system is divided into several intervals, and the identifiers are numbered sequentially. The DL-AoA measurement value measured in the terminal LCS coordinate system each time is located in a specific value interval, and the number of the value interval is the DL-AoA number index.

If the measurement result related to the DL-AoA positioning measurement sent by the terminal to the network device is the DL-AoA number corresponding to each first RSRP measurement value, the amount of reported data can be reduced.

Range of DL-AoA variation;

it should be noted that the DL-AoA variation range is obtained based on DL-AoA measurement values corresponding to all reported first RSRP measurement values.

Specifically, in a DL-AoD measurement process, a group of RSRP measurement values is obtained through measurement, and the terminal selects a part of RSRP measurement values (i.e., a first RSRP measurement value) to report to the network device. The first reported RSRP measurement value corresponds to one DL-AoA measurement value, the DL-AoA measurement values corresponding to all the reported first RSRP measurement values form a set, and the variation range of the value in the set is called as a DL-AoA variation range. If the measurement result related to the DL-AoA positioning measurement sent by the terminal to the network equipment is the DL-AoA variation range, the reported data volume can be reduced.

here, similarly to the above, all DL-AoA measurement values corresponding to the reported first RSRP measurement value form a set, and the terminal can determine whether the DL-AoA changes according to the change of the values in the set.

Here, the terminal side can complete the judgment, the calculation burden of the network equipment side is reduced, and the first indication information can be reported through 1 bit, so that the reported data volume can be reduced.

optionally, whether the orientation of the terminal changes is determined by any one of a DL-AoA measurement value corresponding to each first RSRP measurement value, a DL-AoA number corresponding to each first RSRP measurement value, a DL-AoA change range, and first measurement indication information, or whether the orientation of the terminal changes is determined by a reception beam adjustment capability possessed by the terminal.

It should be noted that the receive beam adjustment capability is a terminal capability. The terminal has acquired the optimal RX beam direction (e.g., via QCL relationships) before receiving the PRS signal. In the positioning measurement process, if the terminal direction changes, the terminal can switch the RX beam, the optimal RX beam is kept to receive the PRS signal, and the reliability of the RSRP measurement value in the measurement process is ensured, so that RSRP measurement errors caused by the change of the RX beam direction are avoided, and the positioning accuracy of the network equipment side on the terminal is further influenced.

Here, the terminal side can complete the judgment, the calculation burden of the network equipment side is reduced, and the second indication information can be reported through 1 bit, so that the reporting quantity can be reduced.

optionally, whether the reception beam of the terminal is changed is determined by any one of a DL-AoA measurement value corresponding to each first RSRP measurement value, a DL-AoA number corresponding to each first RSRP measurement value, a DL-AoA change range, and first measurement indication information, or whether the orientation of the terminal is changed is determined by reception beam adjustment capability possessed by the terminal.

Here, the terminal side can complete the judgment, the calculation burden of the network equipment side is reduced, and the third indication information can be reported through 1 bit, so that the reporting quantity can be reduced.

It should be noted that, in the case that the terminal has the receiving beam adjusting capability, the fourth indication information may be reported. When the terminal receives PRS signals by adopting an optimal RX beam, reporting is carried out by combining with RSRP measurement values, and meanwhile, reporting that DL-AoA in GCS (Global coordination System) is not changed. And when the terminal RX beam is in adjustment, reporting by combining with the RSRP measurement value, and reporting that DL-AoA in a GCS coordinate system changes.

Here, the terminal side can complete the determination, so that the calculation burden of the network device side is reduced, and the fourth indication information can be reported by 1 bit, so that the reporting number can be reduced.

As an optional implementation manner, in step 102 of the method according to the embodiment of the present invention, the controlling, by the terminal, based on the PRS, at least two antenna panels of the terminal to measure specified measurement parameters respectively to obtain a second measurement result includes:

here, the specified measurement parameters include, but are not limited to, RSRP. That is, the specified measurement parameters also include DL-AoA.

It should be noted that, when the specified measurement parameters include RSRP and DL-AoA, based on the PRS, at least two antenna panels are controlled to respectively measure the specified measurement parameters, so as to obtain a plurality of second candidate RSRP measurement values and a plurality of DL-AoA measurement values.

M second candidate RSRP measurement values are selected from the second candidate RSRP measurement values to serve as second RSRP measurement values, M is larger than or equal to 2, and M is a positive integer;

here, the first M second candidate RSRP measurement values in the multiple second candidate RSRP measurement values in descending order may be specifically selected as the second RSRP measurement value.

it should be noted that one DL-AoD measurement includes multiple PRS measurements, and according to the configuration of the network device, at each PRS measurement, one PRS is measured simultaneously by each antenna panel of the terminal. In one PRS measurement, each antenna panel gets a measurement of a specified measurement parameter. Because the antenna panel is distributed at different positions of the terminal and has different receiving directions, the measured values of the specified measurement parameters of different antenna panels in the same PRS measurement can be different, and the network equipment can determine whether the direction of the terminal changes or not by reporting the measured values of the specified measurement parameters of different antenna panels.

In this case, the second measurement result reported to the network device by the terminal includes RSRP measurement values obtained by measuring RSRPs by each antenna panel, so that the network device can know whether the orientation of the terminal changes based on the RSRP measurement values obtained by measuring RSRPs by each antenna panel, thereby obtaining the reliability of each RSRP measurement value, and selecting the RSRP measurement values with consistent reliability to perform positioning calculation, which is beneficial to improving positioning accuracy.

If the M second RSRP measurement values include RSRP measurement values measured by partial antenna panels in at least two of the antenna panels, determining at least one of the M second RSRP measurement values and M second RSRP measurement values as a second measurement result:

here, the measurement value specifically refers to an RSRP measurement value, or an RSRP measurement value and a DL-AoA measurement value.

here, since the measured values of the specified measurement parameters (not limited to RSRP, but also DL-AoA) of different antenna panels in the same PRS measurement may be different, the difference or ratio therebetween may be referred to as a measurement difference value. Here, the terminal reports the measurement difference value obtained by measuring the specified measurement parameter between the antenna panels corresponding to the positioning reference signal resources, so that the reported data volume can be reduced.

The variation range of the measurement difference value obtained by measuring the specified measurement parameters between any two antenna panels;

it should be noted that, since one DL-AoD measurement includes multiple PRS measurements, a measurement difference value of a specified measurement parameter between any two antenna panels can be obtained in each PRS measurement, and the terminal selects a part of PRS measurements to obtain an RSRP measurement value to report to the network device. The measurement difference values of the specified measurement parameters between any two antenna panels corresponding to the PRS measurements (RSRP difference between any two antenna panels or DL-AoA difference between any two antenna panels) form a set. The variation range of the values in the set is referred to as the variation range of the measurement difference of the specified measurement parameter between the antennas panel.

acquiring the reliability of a set of first RSRP measurement values according to the DL-AoA variation range, the first indication information, the second indication information, the third indication information or the fourth indication information, and determining the position of the terminal according to the reliability of the set of the first RSRP measurement values;

it should be noted that, if the network device receives the DL-AoA change range, it shows that the DL-AoA in the terminal LCS coordinate system changes during the whole RSRP measurement process. Based on this information, the network device can obtain the reliability of the set in which the first RSRP measurement value is located, that is, the reliability of the set of RSRP measurement values.

Here, if the DL-AoA variation range varies within a small range, it indicates that the orientation of the terminal has not changed, and the reliability of the set of the first RSRP measurement values is consistent, and positioning calculation may be performed using RSRP measurement values in the set of RSRP measurement values.

If the network equipment receives the first indication information, that is, the network equipment receives whether the DL-AoA in the LCS coordinate system of the terminal changes, the situation that whether the direction of the terminal changes in the whole RSRP measuring process is reflected. Based on this information, the reliability of the set in which the first RSRP measurement value is located, that is, the reliability of the set of RSRP measurement values, can also be obtained.

And if the network equipment receives the second indication information, the network equipment receives whether the position of the terminal is changed. Based on this information, the reliability of the set in which the first RSRP measurement value is located, that is, the reliability of the set of RSRP measurement values, can also be obtained.

If the network device receives the third indication information, the network device receives whether the terminal receiving beam changes. Based on the information, the reliability of the set of the first RSRP measurement values, that is, the reliability of the set of RSRP measurement values, can also be obtained.

If the network device receives the fourth indication information, that is, if the network device receives whether DL-AoA in the GCS coordinate system changes, it indicates whether the terminal receiving beam changes in the whole RSRP measurement process, and based on the information, the reliability of the set where the first RSRP measurement value is located, that is, the reliability of the set of RSRP measurement values can also be obtained.

If the orientation of the terminal is changed, the distribution of values in the DL-AoA measurement values is uneven, and if the DL-AoA measurement values are distributed in a stepped manner (for example, the distribution condition is that the values in the DL-AoA measurement values have a plurality of data groups, the data in each group are relatively close, and the data difference between every two groups is large), the credibility of the group in which the same step is located is consistent, and a first RSRP measurement value in one group is selected for positioning calculation. And if the RSRP is Gaussian distribution, the RSRP measurement value measured at this time is not selected for positioning calculation.

or determining the position of the terminal based on a first RSRP measurement value except for a first RSRP measurement value corresponding to a numerical value of which the difference between any two numerical values in the DL-AoA measurement value or the DL-AoA number is larger than a second preset threshold value;

it should be noted that, if the network device receives the DL-AoA measurement value corresponding to each first RSRP measurement value, the reliability of each first RSRP measurement value is obtained through the DL-AoA value distribution status, and then the first RSRP measurement values with the same reliability are used for positioning calculation, so that the positioning accuracy can be improved; or, the difference between any two values in the DL-AoA measurement values is smaller than the DL-AoA measurement value of the first preset threshold, that is, the first RSRP measurement value corresponding to the DL-AoA measurement value with a relatively close value and a small difference in the DL-AoA measurement values is used for positioning calculation, so that the positioning accuracy can be improved; or, the DL-AoA measurement value with the difference between any two values being greater than the second preset threshold value is eliminated, that is, the first RSRP measurement value corresponding to the DL-AoA measurement value with the larger difference in value among the DL-AoA measurement values is not used for positioning calculation, and the remaining first RSRP measurement value is used for positioning calculation, so that the positioning accuracy can be improved.

If the network equipment receives the DL-AoA numbers corresponding to the first RSRP measurement values, the reliability of each first RSRP measurement value is obtained through the distribution condition of the DL-AoA numbers, and then the first RSRP measurement values with consistent reliability are used for positioning calculation, so that the positioning accuracy can be improved; or, the difference between any two numerical values in the DL-AoA numbers is smaller than the DL-AoA number of the first preset threshold, that is, the first RSRP measurement value corresponding to the DL-AoA number with the numerical value closer and the little difference in the DL-AoA numbers is used for positioning calculation, so that the positioning accuracy can be improved; or, the DL-AoA numbers with the difference between any two numerical values being greater than the second preset threshold value are eliminated, that is, the first RSRP measurement values corresponding to the DL-AoA numbers with the larger difference in value among the DL-AoA numbers are not used for positioning calculation, and the remaining first RSRP measurement values are used for positioning calculation, so that the positioning accuracy can be improved.

As an optional implementation manner, the determining the location of the terminal according to the second measurement result includes:

acquiring the reliability of a set of M second RSRP measurement values according to the variation range of the measurement difference value or the fifth indication information, and determining the position of the terminal according to the reliability of the set of M second RSRP measurement values;

it should be noted that, if the network device receives the variation range of the measurement difference value between any two antenna panels corresponding to each positioning reference signal resource, the variation condition of the value of the measurement difference value measured for the specified measurement parameter between any two antenna panels in the whole RSRP measurement process is reflected, and based on this information, the network device obtains the reliability of the reported set of RSRP measurement values.

And if the network equipment receives the fifth indication information, namely the information about whether the terminal direction changes or not, the situation that whether the terminal direction changes or not in the whole RSRP measuring process is reflected. Based on the information, the network device can obtain the reliability of the reported set of RSRP measurement values.

Or acquiring the reliability of each second RSRP measurement value according to the numerical distribution condition of the difference values, and determining the position of the terminal according to the reliability of each second RSRP measurement value;

or determining the position of the terminal according to a second RSRP measurement value corresponding to a difference value smaller than a third preset threshold value in the difference values;

or, determining the position of the terminal based on a second RSRP measurement value except for a second RSRP measurement value corresponding to a difference value larger than a fourth preset threshold value in the difference values.

Here, if the network device receives the measurement difference value between any two antenna panels corresponding to each positioning reference signal resource, based on this, the network device can obtain the reliability of each reported RSRP measurement value through the distribution status of the measurement difference value between any two antenna panels obtained by each PRS measurement, and then the RSRP measurement values with consistent reliability are used for positioning calculation, so that the positioning accuracy can be improved; or, the difference between any two values in the measurement difference values is smaller than the measurement difference value of the third preset threshold, that is, the RSRP measurement value corresponding to the measurement difference value with a smaller difference, which is closer to the value in the measurement difference values, is used for positioning calculation, so that the positioning accuracy can be improved; or, the difference between any two values in the measurement difference values is larger than the measurement difference value of the fourth preset threshold, that is, the RSRP measurement value corresponding to the measurement difference value with the larger difference in the measurement difference values is eliminated, and is not used for positioning calculation, and the remaining RSRP measurement values are used for positioning calculation, so that the positioning accuracy can be improved.

the preset control signaling is Radio Resource Control (RRC) signaling, media access control unit (MAC-CE) signaling or Downlink Control Information (DCI) signaling.

In the positioning processing method of the embodiment of the present invention, a network device receives a first measurement result and/or a second measurement result sent by a terminal, where the first measurement result is obtained by the terminal performing reference signal received power RSRP measurement and downlink arrival angle DL-AoA measurement respectively based on a received positioning reference signal PRS, and the second measurement result is obtained by the terminal controlling at least two antenna panels of the terminal to measure specified measurement parameters respectively based on the PRS, and a location of the terminal is determined according to the first measurement result and/or the second measurement result.

The following describes the implementation process of the method of the present invention in terms of interaction between the terminal and the network device.

Example one based on DL-AoA measurements

S1: the terminal reports the terminal capability to the network equipment;

here, if the terminal has the receiving beam adjusting capability, the terminal reports the receiving beam adjusting capability to the network device.

S2: based on the terminal capability reported by the terminal, the network equipment configures terminal side DL-AoA measurement parameters and a reporting mode;

s3: a terminal receives a DL-AoA measurement parameter and a reporting mode issued by network side equipment;

s4: and when the terminal measures the DL RSRP based on the received PRS, the terminal simultaneously measures DL-AoA in a terminal LCS coordinate system.

It should be noted that m RSRP measurement values can be obtained by one DL-AoD measurement, and n RSRP measurement values (specifically, the first n RSRP measurement values in the m RSRP measurement values sorted from large to small) are selected and used for reporting to the network device. Here, each RSRP measurement corresponds to one DL-AoA measurement.

Mode 1: a DL-AoA measurement value in a UE LCS coordinate system corresponding to each RSRP;

mode 2: DL-AoAindex in UE LCS coordinate system corresponding to each RSRP;

mode 3: range of DL-AoA variation.

Mode 4: whether the DL-AoA in the terminal LCS coordinate system changes.

Mode 5: whether the orientation of the terminal has changed.

Mode 6: whether the terminal's RX beam direction changes.

Mode 7: whether the DL-AoA in the GCS coordinate system of the terminal changes or not.

S6: and the terminal reports the n RSRP measurement values to the network equipment and obtains a related measurement result based on a reporting mode.

S7: and the network equipment receives the measurement result reported by the terminal, and performs positioning calculation to obtain the position of the terminal.

Here, how to perform positioning calculation on the related measurement results obtained based on different reporting modes to obtain the position of the terminal is already explained in the foregoing, and is not described here again.

Example two different antenna Panel based measurements

S11: the terminal reports the terminal capability;

here, if the terminal has a plurality of antenna panels, the terminal reports the antenna panels to the network device.

S12: based on the terminal capability reported by the terminal, the network equipment configures the terminal side positioning measurement parameters and the reporting mode;

s13: a terminal receives a positioning measurement parameter and a reporting mode issued by network side equipment;

s14: if the terminal has t antenna panels, one PRS is measured simultaneously by the t antenna panels of the terminal for each PRS measurement.

Here, one DL-AoD measurement includes m PRS measurements, each of which outputs measured values corresponding to t designated measurement parameters. And selecting n RSRP measurement values for reporting to the network equipment. The n RSRP measurement values belong to a certain PRS measurement, respectively. Here, the specified measurement parameters include RSRP and may also include DL-AoA. That is, each time PRS measurement is performed, the t antenna panels panel are respectively used to measure RSRP based on PRS, and DL-AoA in the LCS coordinate system of the terminal is measured at the same time.

S14: the terminal determines one or more reporting modes based on the configuration of the network equipment. Specifically, based on PRS measurements corresponding to n RSRP measurement values, a multi-antenna panel related measurement result corresponding to a reporting mode is calculated.

Mode 1: when reporting RSRP, reporting the measured values corresponding to the specified measurement parameters of each antenna panel corresponding to each downlink positioning reference signal resource DL PRS resource;

mode 2: when reporting RSRP, reporting a measured value difference value corresponding to a specified measurement parameter between any two antenna panels corresponding to each DL PRS resource;

mode 3: when reporting RSRP, reporting the variation range of the measured value difference value corresponding to the specified measurement parameter between any two antenna panels corresponding to each DL PRS resource;

mode 4: and reporting whether the terminal direction changes or not when reporting the RSRP.

Here, whether the orientation of the terminal is changed may be determined based on the amount of change in the measured value difference value.

S15: and the network equipment reports n RSRP measurement values and the multi-antenna panel related measurement result corresponding to the reporting mode.

S16: and the network equipment receives the measurement result reported by the terminal, and performs positioning calculation to obtain the position of the terminal.

Here, how to perform positioning calculation on the related measurement results obtained based on different reporting modes to obtain the position of the terminal is already explained in the foregoing, and details are not described here.
