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

The PRS is a signal used by a network device to locate a terminal. The PRS is transmitted in resource blocks in the downlink subframe configured for PRS transmission. The PRS corresponds to identification information such as a positioning reference signal resource identification and a sequence identification.

In related technologies, after the terminal establishes a radio resource control (Radio Resource Control, RRC) connection, the location server uses the LTE positioning protocol (LTE positioning Protocol, LPP) to send the positioning measurement configuration of the PRS to the terminal through the interface between the location server and the terminal. . The positioning measurement configuration includes the identification information of the PRS received by the terminal and the priority order of the PRS (Priority Order). The above priority order is mainly to instruct the terminal to try to measure some transmission reference points (Transmission Reference) that are closer to the terminal. Point, TRP) sent by the PRS. The terminal determines the PRS that needs to be measured and reported according to the above positioning measurement configuration.

Wherein, the above-mentioned 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 also includes: an idle (RRC_Idle) state and an inactive (RRC_Inactive) state. Wherein, the idle state means 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 fast data transmission in the connected state, however, the resource consumption of the terminal and the resource consumption of the network device in the long-term connected state are high. It takes a long time to switch from the idle state to the connected state. Therefore, while reducing resource consumption, the delay in entering the connected state is reduced, and an inactive state is introduced, which is a state between the connected state and the idle state.

Since there is no discussion on how to measure and report PRS for inactive terminals in the current NR system, there are currently two ways to obtain the positioning measurement configuration for inactive terminals: the first is that the terminal is connected Receive and save the above positioning measurement configuration in the state. When the terminal turns into an inactive state, use the positioning measurement configuration received in the connected state to perform PRS measurement and report according to the positioning measurement configuration; the second is based on the current serving base station System Information (System Information) to obtain.

However, when the terminal in the inactive state uses the positioning measurement configuration received in the connected state, there will be a problem of the validity of the positioning measurement configuration. For example, the positioning measurement configuration gives the priority of each reference signal. In fact, the priority of this positioning reference signal resource is determined based on the approximate location when the terminal is in the connected state. For example, the terminal is in a position closer to TRP1 and TRP2. , then the priority of the positioning reference signal resources sent by TRP1 and TRP2 will be higher. Another example is that the positioning measurement configuration provides that the reference value of the method based on time measurement is based on a certain PRS resource, which is also determined based on the approximate location of the terminal. When the terminal is in the inactive state, if the location changes, the priority information will be outdated, that is, invalid. If the above positioning measurement configuration is used for PRS measurement and reporting, it will affect the terminal's ability to perform measurement results. reported accuracy.

Based on this, the present disclosure provides a positioning measurement method, and provides a solution for how to ensure the validity of the PRS measured and reported by the terminal when the terminal is in an inactive state.

Specifically, for example, the UE can report the measurement results of M PRSs at most, so according to the priority, the UE reports the measurement results of the M PRSs with the highest priority. However, according to the measurement of arrival time, how to judge the priority configuration timeliness in this configuration information can be based on one of the following judgment conditions:

Condition 1: The M PRSs with the earliest arrival time are different from the M PRSs with the strongest priority.

The differences are present in at least one, or at least X, or all.

Condition 2: The PRS with the earliest arrival time is not among the M PRSs with the strongest priority.

Condition 3: The PRS with the earliest arrival time is not the PRS with the strongest priority.

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

The time of arrival may be the time of arrival of the first path or the time of arrival of multiple paths.

Specifically, for example, the UE can report the measurement results of M PRSs at most, so according to the priority, the UE reports the measurement results of the M PRSs with the highest priority, and the M PRSs come from the L TRPs. However, according to the measurement of arrival time, how to judge the priority configuration timeliness in this configuration information can be based on one of the following judgment conditions:

Condition 1: The L TRPs with the earliest arrival time are different from the L TRPs with the strongest priority.

The differences are present in at least one, or at least Y, or all.

Condition 2: The TRP with the earliest arrival time is not among the L TRPs with the highest priority.

Condition 3: The TRP with the earliest arrival time is not the TRP with the strongest priority

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

(a) For comprehensive judgment, the RSRP can be considered first, and if the RSRP is the same, the arrival time should be considered; or vice versa.

(b) Comprehensive judgment, the two can also occupy different weights, such as 0.5 and 0.5, or one weight is larger and the other weight is less.

(4) After the terminal determines that the configuration information is invalid, the terminal acts.

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

2) Report the measurement results based on the new reference PRS and report the reference PRS ID. 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 initiate random access to enter the connected state, and reacquire new PRS configuration.

4), or use the SDT (small data transmission) method to request a new PRS configuration.
