Technical Field

The present application relates to the field of communications technologies, and in particular, to a positioning measurement method, apparatus, device, and storage medium.

Background

A base station needs to measure the position of a User Equipment (UE) in a cell, including the position of the UE through a Positioning Reference Signal (PRS). That is, the UE in the connected state receives the positioning measurement configuration from the base station, and reports the measurement result corresponding to the PRS to the base station according to the positioning measurement configuration, and the base station determines the location information of the UE according to the measurement result.

Since the NR Rel-16 system only considers measurement and reporting of PRS of connected UE, but does not discuss how to measure and report PRS of inactive UE, the positioning measurement configuration currently acquired for the inactive UE is configured by the UE in the connected state, that is, when the UE changes to the inactive state, the positioning measurement configuration configured in the connected state is used.

However, since the positioning measurement configuration is a configuration obtained by the UE in a connected state, when the UE enters an inactive state, there may be a situation that the location of the UE changes, and information indicated in the positioning measurement configuration may have a failure problem, thereby affecting the accuracy of reporting the measurement result by the UE.

The technical scheme described in the embodiment of the present disclosure may be applied to a 5GNR system, and may also be applied to a subsequent evolution system of a 5G NR system.

In order to determine the position of the terminal, the terminal receives the PRS sent by the network device, and measures and reports the PRS.

PRS are signals used by network devices to locate terminals. PRSs are transmitted in resource blocks within a downlink subframe configured for PRS transmission. The PRS corresponds to identification information such as a positioning reference signal resource identification, a sequence identification and the like.

In the related art, after a terminal establishes Radio Resource Control (RRC) connection, a location server sends positioning measurement configuration of a PRS to the terminal through an interface between the location server and the terminal by using an LTE Positioning Protocol (LPP). The positioning measurement configuration includes identification information of PRS received by the terminal and a Priority Order (Priority Order) of the PRS, where the Priority Order is mainly used to instruct the terminal to measure PRS transmitted by Transmission Reference Points (TRPs) that are close to the terminal as much as possible. And the terminal determines the PRS which needs to be measured and reported according to the positioning measurement configuration.

Wherein the terminal is in a Connected (RRC _ Connected) state. In addition to the above connection state, the connection state between the terminal and the network device further includes: an Idle (RRC _ Idle) state and an Inactive (RRC _ Inactive) state. The idle state refers to that no RRC connection is established between the UE and the network device. The connected state means that an RRC connection has been established between the terminal and the network device, and the RRC connection is in an active state. The inactive state means that an RRC connection has been established between the terminal and the network device, but the RRC connection is in the inactive state. The terminal and the network device can realize rapid data transmission in the connected state, however, the resource consumption of the terminal and the resource consumption of the network device are high in the connected state for a long time. And the switch from the idle state to the connected state requires longer time consumption, so that the time delay of entering the connected state is reduced while the resource consumption is reduced, and the state between the connected state and the idle state is introduced into the inactive state.

Since there is no discussion about how PRS measurement and reporting is performed for an inactive terminal in the current NR system, there are two ways for how positioning measurement configuration for an inactive terminal is obtained: the first is that the terminal receives and stores the positioning measurement configuration in a connected state, and when the terminal is converted into an inactivated state, the positioning measurement configuration received in the connected state is used for carrying out measurement and report of the PRS according to the positioning measurement configuration; the second is acquisition based on System Information (System Information) of the current serving base station.

However, when a terminal in an inactive state uses a positioning measurement configuration received while in a connected state, a problem of validity of the positioning measurement configuration may occur. For example, the priority of each reference signal is given by the positioning measurement configuration, and in fact, the priority of the positioning reference signal resource is determined based on the approximate position when the terminal is in the connected state, for example, the terminal is located at a position closer to TRP1 and TRP2, then the priority of the positioning reference signal resource transmitted by TRP1 and TRP2 is higher. Also for example, the positioning measurement configuration gives a reference value for a time measurement based method based on certain PRS resources, which is also determined based on the approximate location of the terminal. When the terminal is switched to the inactive state, if the position changes, the priority information will be outdated, that is, invalid, and if the positioning measurement configuration is used for measuring and reporting the PRS, the accuracy of reporting the measurement result by the terminal is affected.

Based on this, the present disclosure provides a positioning measurement method, which provides a solution for how to ensure the validity of PRS for measurement and reporting by a terminal when the terminal is in an inactive state. The technical solution provided by the present application is described below by means of several embodiments.

and (I) the difference between the h TRPs with the highest priority in the fourth priority and the h TRPs with the highest priority in the TRP reference priority exceeds a second threshold, wherein the fourth priority is determined by the arrival time information of the j TRPs, and the reference priority of the TRP is determined according to the PRS reference priority corresponding to the k PRSs.

In some embodiments, the fourth priority is obtained by ranking the j TRPs according to the order of arrival time, that is, the earlier the arrival time of the TRP is, the higher the priority level of the TRP in the fourth priority is.

That is, the h TRPs with the earliest arrival time are different from the h TRPs with the highest priority among the TRP reference priorities. The above differences are represented by at least one TRP difference, or at least y differences, 1 < y < h, or all differences, which are not limited herein.

Optionally, the resource configuration information indicates a second reference TRP, or when the resource configuration information indicates a second reference RPS, the TRP corresponding to the second reference RPS is determined as the second reference TRP.

Optionally, a target priority is corresponding to the RSRP and the time of arrival information. In one example, if the priority of RSRP is higher than the arrival time information, a fifth priority corresponding to the PRS is preferentially determined according to the RSRP, and if at least two PRSs have the same RSRP, the fifth priority is determined according to the arrival time information; or if the priority of the arrival time information is higher than the RSRP, preferentially determining a fifth priority corresponding to the PRS according to the arrival time information, and if the arrival time information of at least two PRSs is the same, determining according to the RSRP. The target priority may be preset by the terminal, or may be indicated by the location server and/or the access network device, which is not limited herein.

Illustratively, according to the target weight relationship, the RSRP and the arrival time information are integrated to calculate evaluation scores corresponding to the PRSs, and ranking is performed according to the evaluation score of each PRS to obtain a fifth priority of the PRS. The target weight relationship may be preset by the terminal, or may be indicated by the location server and/or the access network device, which is not limited herein.

When the terminal determines that the resource configuration information is in the failure state, reporting is performed according to the RSRP or the arrival time information of the k PRSs, that is, when the terminal completes measurement and/or reporting of the PRSs by the technical scheme provided by the embodiment of the application, even if the resource configuration information is determined to be in the failure state, the positioning measurement result can be timely reported to the location server and/or the access network equipment, and the terminal does not need to re-enter the connection state to acquire new resource configuration information, so that the terminal can measure the PRSs without a measurement interval, and the positioning measurement delay is reduced.

steps

After the location server and/or the access network device receives the resource configuration information request, new resource configuration information is fed back to the terminal in a small data transmission mode, and the terminal can measure and/or report the PRS according to the new resource configuration information.

Illustratively, step 9021 and step 9022 are implemented as two parallel steps, that is, step 901, step 9021 and step 9031 are implemented as one scheme, and step 901 and step 9022 are implemented as another scheme.

When the terminal determines that the resource configuration information is in the failure state, the terminal acquires new resource configuration information from the location server and/or the access network device again to perform measurement and/or report of the PRS according to the new resource configuration information, that is, when the measurement and/or report of the PRS by the terminal is completed by the technical scheme provided by the embodiment of the application, if the resource configuration information is determined to be in the failure state, the terminal acquires the new resource configuration information without using the failed resource configuration information, thereby improving the accuracy of the PRS measurement and/or report.

The concept of the scheme of the embodiment of the disclosure is as follows:

the terminal receives positioning reference signal resource configuration and/or reporting information sent by network equipment, and when the terminal is in an RRC _ inactive state, the terminal judges the validity of the PRS configuration and/or reporting information.

a) The network device includes a Location Management Function (LMF) and/or a serving base station.

(II) the positioning reference signal resource configuration information comprises at least one of the following:

a) configuration information of positioning reference signals:

i. positioning reference signal set ID, positioning reference signal resource ID, occupied time domain position, frequency domain position, sequence ID and the like.

The positioning reference signal may be transmitted periodically, aperiodically, or semi-persistent.

Priority of a set of positioning reference signal resources.

Priority order of individual PRSs: this priority order is given primarily to instruct the terminal to try to measure PRS transmitted by some TRPs closer to the terminal.

nr-DL-PRS-ReferenceInfo: it is mainly given which PRS time is referred to when the time-based measurement is made.

1. The method based on time measurement comprises the following steps:

(a) a reference signal time difference RSTD, a reference signal time difference;

(b) receiving a sending time difference value and an RxTx time difference value;

(c) relative arrival time: relative time of arrival;

(d) time difference of arrival: time difference of arrival.

(III) how the terminal judges the validity:

1) and the terminal measures the RSRP of each PRS and judges the effectiveness of the RSRP.

(a) For example, the terminal determines the priority and/or reference PRS of each PRS according to the RSRP of each PRS:

the RSRP may be L1-RSRP or L3-RSRP; the RSRP may be an RSRP of a first path or an RSRP of a multipath.

Specifically, for example, the UE may report the measurement results of M PRSs at most, and then the UE reports the measurement results of M PRSs with the highest priority according to the priority. However, in view of RSRP measurement, how to determine the priority configuration aging in this configuration information may be determined according to one of the following determination conditions:

the first condition is as follows: the M PRSs with the strongest RSRP are different from the M PRSs with the strongest priority.

The differences may be at least one, at least X, or all.

And a second condition: the PRS with the strongest RSRP is not among the M PRSs with the strongest priority.

And (3) carrying out a third condition: the PRS with the strongest RSRP is not the one with the strongest priority.

(b) Or the terminal judges the priority and/or reference PRS of the PRS according to the RSRP of each TRP, wherein the RSRP of each TRP is the average value of the N strongest RSRPs contained in each TRP or the RSRP of the strongest PRS in the TRP.

Specifically, for example, the UE can report the measurement results of M PRSs at most, and then the measurement results of M PRSs with the highest priority are reported by the priority UE, where the M PRSs are from L TRPs. However, in view of RSRP measurement, how to determine the priority configuration aging in this configuration information may be determined according to one of the following determination conditions:

the first condition is as follows: the L TRPs with the strongest RSRP are different from the L TRPs with the strongest priority.

The differences may be at least one, or at least Y, or all.

And a second condition: the TRP with the strongest RSRP is not among the L TRPs with the strongest priority.

And (3) carrying out a third condition: the TRP with the strongest RSRP is not the TRP with the strongest priority.

2) And the terminal measures the arrival time of each PRS and judges the validity of the PRS according to the arrival time.

(a) And the terminal judges the priority and/or reference PRS of each PRS according to the arrival time of all paths or the arrival time of the first path of each PRS.

Specifically, for example, the UE may report the measurement results of M PRSs at most, and then the UE reports the measurement results of M PRSs with the highest priority according to the priority. However, how to judge the priority configuration aging in this configuration information according to the measurement of the arrival time may be determined according to one of the following judgment conditions:

the first condition is as follows: the M PRSs with the earliest arrival time are different from the M PRSs with the strongest priority.

The differences may be at least one, at least X, or all.

And a second condition: the PRS with the earliest arrival time is not among the M PRSs with the strongest priority.

And (3) carrying out a third condition: the PRS with the earliest arrival time is not the PRS with the strongest priority.

(b) Or the terminal judges the priority and/or reference PRS of the PRS according to the arrival time of each TRP, wherein the arrival time of each TRP is the average value of the arrival times of the N PRSs with the earliest arrival time contained in each TRP or the value of the arrival time of the PRS with the earliest arrival time contained in the TRP.

The time of arrival may be the time of arrival of a first path or the time of arrival of a multipath.

Specifically, for example, the UE can report the measurement results of M PRSs at most, and then the measurement results of M PRSs with the highest priority are reported by the priority UE, where the M PRSs are from L TRPs. However, how to judge the priority configuration aging in this configuration information according to the measurement of the arrival time may be determined according to one of the following judgment conditions:

the first condition is as follows: the L TRPs with the earliest arrival time are different from the L TRPs with the strongest priority.

The differences may be at least one, or at least Y, or all.

And a second condition: the TRP with the earliest arrival time is not among the L TRPs with the strongest priority.

And (3) carrying out a third condition: the TRP with the earliest arrival time is not the TRP with the strongest priority

3) And the terminal comprehensively judges the priority and/or reference PRS of each PRS according to the arrival time and the RSRP of each PRS.

(a) Comprehensive judgment, RSRP can be considered firstly, and if the RSRP is the same, the arrival time is considered; or vice versa.

(b) The integrated judgment may be that the two occupy different weights, such as 0.5 and 0.5, or one weight is larger and the other is smaller.

And fourthly, after the terminal judges that the configuration information is invalid, the terminal acts.

1) Reporting the measurement result of the PRS based on the new priority, such as reporting the M PRSs with the strongest RSRP, or reporting the measurement result of the M PRSs with the earliest arrival time (angle-based method)

2) And reporting the measurement result based on the new reference PRS, and reporting the ID of the reference PRS. For example, the new reference PRS is the PRS with the strongest RSRP or the PRS with the earliest arrival time (time-based method)

3) Or initiating random access to enter a connection state, and reacquiring a new PRS configuration.

4) Or request a new PRS configuration using an sdt (small data transmission) method.
