In order to determine the position of the terminal, the terminal receives the PRS sent by the network equipment, and measures and reports the PRS.
PRS is a signal used by a network device to locate a terminal. PRS are transmitted in resource blocks within a downlink subframe configured for PRS transmission. The PRS corresponds to identification information such as positioning reference signal resource identification, sequence identification and the like.
In the related art, after a terminal establishes a radio resource control (Radio Resource Control, RRC) connection, a location server transmits a positioning measurement configuration of PRS to the terminal through an interface between the location server and the terminal using an LTE positioning protocol (LTE positioning Protocol, LPP). The positioning measurement configuration includes the identification information of PRS received by the terminal and the Priority Order (Priority Order) of PRS, where the Priority Order is mainly used to instruct the terminal to measure PRS sent by some transmission reference points (Transmission Reference Point, TRP) that are as close to the terminal as possible. And the terminal determines PRS needed 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 states, the connection states between the terminal and the network device include: an Idle (rrc_idle) state and an Inactive (rrc_inactive) state. The idle state refers to that no RRC connection has been 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 an inactive state. The terminal and the network device can realize rapid data transmission in the connection state, however, the resource consumption of the terminal and the resource consumption of the network device are high in the connection state for a long time. And a longer time is required for switching from the idle state to the connection state, so that the time delay for entering the connection state is reduced while the resource consumption is reduced, and the state between the connection state and the idle state is introduced into the inactive state.
Since no discussion is made on how PRS measurements and reporting are performed for the terminal in the inactive state in the current NR system, there are two approaches to how positioning measurement configuration is obtained for the terminal in the inactive state: the first is that the terminal receives and stores the positioning measurement configuration when in a connection state, and when the terminal is switched to a non-activation state, the positioning measurement configuration received when in the connection state is used for carrying out PRS measurement and reporting according to the positioning measurement configuration; the second is acquired based on system information (System Information) of the current serving base station.
However, when a terminal in an inactive state uses a location measurement configuration received while in a connected state, a problem of validity of the location measurement configuration may occur. For example, the positioning measurement configuration gives the priority of each reference signal, and in fact, the priority of the positioning reference signal resource is determined based on the approximate location when the terminal is in the connected state, for example, the terminal is located closer to TRP1 and TRP2, and then the priority of the positioning reference signal resource transmitted by TRP1 and TRP2 is higher. Also for example, the positioning measurement configuration gives that the reference value of the time measurement based method is based on a certain PRS resource, which is also determined based on the approximate location of the terminal. When the terminal is switched into the inactive state, if the position changes, the priority information will be outdated, namely invalid, if the positioning measurement configuration is used for PRS measurement and reporting, 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 guarantee the validity of PRS measured and reported by a terminal when the terminal is in an inactive state. The technical scheme provided by the application is described and illustrated by the following embodiments.
Referring to fig. 2, a flowchart of a positioning measurement method according to an embodiment of the disclosure is shown. The method may be applied in a terminal in the communication system shown in fig. 1. The method comprises the following steps.

Optionally, the arrival time information includes at least one of a reference PRS time difference value, a receive transmit time difference value, a relative arrival time, and an arrival time difference.

In response to entering the connected state, new resource configuration information sent by the location server and/or the access network device is received, step 9031.
In the embodiment of the application, when the resource configuration information is determined to be in a failure state, the terminal needs to re-activate the RRC connection with the access network equipment so as to acquire new resource configuration information from the location server and/or the access network equipment, and measure and/or report PRS (radio resource configuration) according to the new resource configuration information.
In step 9022, when the resource configuration information is in the failure state, a transmission method of small data transmission is used to transmit the resource configuration information request.
The transmission mode of the small data transmission (SMALL DATA transmission) has less influence on the network, such as signaling overhead, network resources, reconfiguration delay and the like. After the position server and/or the access network equipment receives the resource configuration information request, the terminal feeds back new resource configuration information to the terminal in a transmission mode of small data transmission, and the terminal can measure and/or report PRS according to the new resource configuration information.
Illustratively, steps 9021 and 9022 are implemented as two side-by-side steps, i.e., steps 901, 9021, 9031 are implemented as one scheme, and steps 901 and 9022 are implemented as another scheme.
In summary, according to the technical scheme provided by the embodiment of the application, when the terminal in the inactive state needs to perform measurement and/or reporting of the PRS, the validity of the resource configuration information of the PRS received in the connection state is determined, so as to ensure the validity of the PRS performing measurement and/or reporting.
When the terminal determines that the resource configuration information is in the failure state, the terminal acquires new resource configuration information from the position server and/or the access network equipment again so as to measure and/or report the PRS according to the new resource configuration information, namely, when the terminal finishes measuring and/or reporting the PRS by using the technical scheme provided by the embodiment of the application, if the resource configuration information is judged to be in the failure state, the terminal acquires the new resource configuration information without using the failed resource configuration information, and the accuracy of measuring and/or reporting the PRS is improved.

(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, etc.
The positioning reference signal may be periodic, aperiodic, or semi-persistent.
Locating the priority of the set of reference signal resources.
Priority order of each PRS: this priority order is mainly given to instruct the terminal to measure PRS transmitted by some TRPs as close as possible to the terminal.
Nr-DL-PRS-ReferenceInfo: mainly giving which PRS time to reference when making time-based measurements.
1. The method based on time measurement comprises the following steps:
(a) A reference signal time difference value RSTD REFERENCE SIGNAL TIME DIFFERENCE;
(b) Receiving a transmission time difference value, rxTx time difference values;
(c) Relative arrival time: RELATIVE TIME of arival;
(d) Time difference of arrival: TIME DIFFERENCE of arival.
(III) how the terminal judges the validity:
1) The terminal measures the RSRP of each PRS and judges the validity according to 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 the RSRP of the first path or the RSRP of the multipath.
Specifically, for example, the UE may report the measurement results of M PRSs at most, and then, according to the priority, the UE reports the measurement results of M PRSs with the highest priority. However, from the perspective of RSRP measurement, how to determine the priority configuration age in this configuration information may be based on one of the following determination conditions:
condition one: the M PRSs with the strongest RSRP are different from the M PRSs with the strongest priorities.
The differences are embodied in at least one difference, or at least X differences, or all differences.
Condition II: the PRS with the strongest RSRP is not among the M PRSs with the strongest priorities.
And (3) a third condition: the PRS with the strongest RSRP is not the PRS with the strongest priority.
(B) Or the terminal judges the priority/REFERENCE PRS of the PRS according to the RSRP of each TRP, wherein the RSRP of each TRP is the average value of N strongest RSRPs contained by each TRP or the RSRP of the strongest PRS in the TRP.
The RSRP may be L1-RSRP or L3-RSRP; the RSRP may be the RSRP of the first path or the RSRP of the multipath.
Specifically, for example, the UE may report the measurement results of M PRSs at most, and then, according to the priority, the UE reports the measurement results of M PRSs with the highest priority, where the M PRSs are from L TRPs. However, from the perspective of RSRP measurement, how to determine the priority configuration age in this configuration information may be based on one of the following determination conditions:
condition one: the L TRPs with the strongest RSRP are different from the L TRPs with the strongest priorities.
The differences are embodied in at least one difference, or at least Y differences, or all differences.
Condition II: the TRP with the strongest RSRP is not among the L TRPs with the strongest priorities.
And (3) a third condition: the TRP with the strongest RSRP is not the one with the strongest priority.
2) The terminal measures the arrival time of each PRS and judges the validity 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 of each PRS or the arrival time of the first path.
Specifically, for example, the UE may report the measurement results of M PRSs at most, and then, according to the priority, the UE reports the measurement results of M PRSs with the highest priority. However, from the measurement of the arrival time, how to determine the aging of the priority configuration in this configuration information may be based on one of the following determination conditions:
Condition one: the M PRSs with the earliest arrival time are different from the M PRSs with the strongest priorities.
The differences are embodied in at least one difference, or at least X differences, or all differences.
Condition II: the PRS with the earliest arrival time is not among the M PRSs with the strongest priorities.
And (3) 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/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 earliest arrival times contained in each TRP or the arrival time value with earliest arrival times in the PRSs contained in the TRP.
The arrival time may be the arrival time of the first path or the arrival time of the multipath.
Specifically, for example, the UE may report the measurement results of M PRSs at most, and then, according to the priority, the UE reports the measurement results of M PRSs with the highest priority, where the M PRSs are from L TRPs. However, from the measurement of the arrival time, how to determine the aging of the priority configuration in this configuration information may be based on one of the following determination conditions:
condition one: the L TRPs with the earliest arrival time are different from the L TRPs with the strongest priorities.
The differences are embodied in at least one difference, or at least Y differences, or all differences.
Condition II: the TRP with the earliest arrival time is not among the L TRPs with the strongest priorities.
And (3) 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) The comprehensive judgment can be carried out by considering RSRP firstly, and if the RSRP is the same, the arrival time is considered; or vice versa.
(B) The comprehensive judgment can also be that the two occupy different weights, such as 0.5 and 0.5, or one weight is larger and the other weight is smaller.
And fourthly, after the terminal judges that the configuration information is invalid, the terminal acts.
1) Reporting PRS measurement results based on new priority, such as reporting M PRSs with strongest RSRP, or reporting M PRSs with earliest arrival time (angle-based method)
2) Report the measurement results based on the new REFERENCE PRS and report REFERENCE PRS ID. For example, new REFERENCE PRS is the strongest PRS of RSRP or the earliest PRS of arrival time (time-based method)
3) Or initiating random access to enter a connection state, and re-acquiring new PRS configuration.
4) Or request a new PRS configuration using an SDT (SMALL DATA transmission) method.
