Optionally, in one embodiment of the present disclosure, a new work item description (WID) on extending and improving NR positioning is approved in the Radio Access Network (RAN) protocol. One of the core goals is to specify positioning measurement requirements for Low Power High Accuracy Positioning (LPHAP) use-case 6.

Specifically, the enhancements to LPHAP use-case 6 defined in the following related protocols are enabled:

1. Extend the eDRX cycle duration to more than 10.24s in the network resource suspension state (RRC_INACTIVE) to meet the battery life requirements of LPHAP.

Among them, positioning-specific enhancements for eDRX cycles exceeding 10.24 seconds are defined as part of the Rel-18 standard working instruction (WI) and can be used to expand and improve NR positioning.

Work on this goal should be coordinated with work on Rel-18WI on e-Reduced Capability (eRedCap). To this end, the functionality to extend the eDRX cycle beyond 10.24 seconds should be defined as part of Rel-18WI on eRedCap.

Additionally, input from RAN1 can be facilitated via LS when necessary.

2. For UL and DL+UL positioning of UEs in RRC_INACTIVE state, SRS configuration enhancements may be specified based on the SRS positioning validity area to avoid frequent network resource (Radio Resource Control, RRC) connections for SRS (re)configuration [RAN2, RAN1, RAN3].

Among them, SRS can be used for positioning configuration in multiple cells. And the details including interference, timing advance, spatial relationship information, path loss reference and common SRS parameters across multiple cells can be further discussed in normative work.

Among them, one or more SRSs may be pre-configured for positioning configuration [RAN2, RAN3].

Among them, the SRS [RAN2, RAN1] used for positioning activation/request procedures can be pre-configured.

3. A DL Positioning Reference Signal (PRS) measurement solution can be specified for UEs in the RRC_IDLE state and report measurements in the RRC_CONNECTED state [RAN2].

4. An alignment solution between eDRX and PRS configurations may be specified [RAN2].

5. Corresponding new core requirements may be specified, as well as the impact on existing RAN4 specifications identified and specified, including Radio Resource Management (RRM) measurements and procedures [RAN4].

However, when the UE transmits SRS according to UL timing, it has not yet been determined how to define the method and UE behavior of LPHAP so that the UE can perform positioning in the RRC_INACTIVE state.

A positioning measurement method, apparatus, device, and storage medium provided by an embodiment of the present disclosure are described in detail below with reference to the accompanying drawings.

FIG2 is an interactive schematic diagram of a positioning measurement method provided by an embodiment of the present disclosure. As shown in FIG2 , the method may include the following steps:

Step S2101, the terminal adjusts the UL timing;

It should be noted that Table (1) shows the measurement accuracy of the UE positioning receive-transmit (Rx-Tx) time difference in frequency range 1 (FR1) in units of additive white Gaussian noise (AWGN). As shown in Table (1):

Where minimum input output (minimum Io) represents the average Io per resource element (RE) over all physical layer minimum granularity resources in an OFDM symbol. Io can be defined in PRS slots. The same Io range applies to PRS and non-PRS symbols. PRS and non-PRS symbols in the same slot have different Io levels.

Among them, PRS resource duplication can be expressed as follows: Sure, and High-level parameter configuration may be adopted, for example, DL-PRS-Resource Repetition Factor, DL-PRS-Num Symbols, and DL-PRS-Combing Definition in the relevant protocols may be adopted.

Here, Tc refers to the basic timing unit defined in the relevant protocol.

Among them, NOTE 6 means that the same frequency band and the same Io conditions for each frequency band apply to this requirement, which is the same as the corresponding requirement of the PRS bandwidth of the minimum resource blocks (RB) number of the corresponding sub carrier space (SCS).

Here, δ refers to the margin determined in the relevant protocol.

Optionally, in one embodiment of the present disclosure, in order to timely update the correct UL timing to ensure the positioning reception-transmission time difference measurement accuracy requirement required in Table (1), the UE needs to trigger UL timing adjustment when at least one condition is met.

In one embodiment of the present disclosure, when the terminal adjusts the UL timing, the terminal may meet at least one of the following conditions:

Support autonomous adjustment of TA;

SRS validity period conditions;

A cell reselection occurs and the first trigger condition is met;

No cell reselection occurs and the second trigger condition is met.

For example, in one embodiment of the present disclosure, the terminal can autonomously adjust the UL timing when it supports autonomous adjustment of TA, meets the SRS validity period condition, cell reselection occurs, and meets the first trigger condition. Alternatively, the terminal can autonomously adjust the UL timing when it supports autonomous adjustment of TA, meets the SRS validity period condition, no cell reselection occurs, and meets the second trigger condition. Alternatively, the terminal can autonomously adjust the UL timing when it supports autonomous adjustment of TA and meets the SRS validity period condition. Alternatively, the terminal can autonomously adjust the UL timing when it supports autonomous adjustment of TA. Alternatively, the terminal can autonomously adjust the UL timing when it meets the SRS validity period condition. Alternatively, the terminal can autonomously adjust the UL timing when cell reselection occurs and the first trigger condition is met. Alternatively, the terminal can autonomously adjust the UL timing when no cell reselection occurs and the second trigger condition is met.

Optionally, in one embodiment of the present disclosure, TA may be used for UE uplink transmission, which means that in order to ensure that the UE uplink packet arrives at the eNB at a desired time, the radio frequency transmission delay caused by the distance is estimated and the data packet is sent in advance by a corresponding time.

In one embodiment of the present disclosure, the UE may maintain the TA in the serving cell. For example, the UE may maintain the TA in the last serving cell.

Optionally, in an embodiment of the present disclosure, the SRS validity period condition may be, for example, that the terminal is within the SRS positioning validity period area.

Among them, in one embodiment of the present disclosure, in the case of LPHAP, UL timing is crucial to ensure higher accuracy for transmitting SRS, especially in the RRC_INACTIVE state. In this case, if the UE is in the RRC_INACTIVE state and moves within the valid area, the TA value will not be updated. This may cause the TA to be misaligned, resulting in a decrease in positioning accuracy. Therefore, when positioning is performed by a UE in the RRC_INACTIVE state within the SRS positioning validity period area, the determination of the UL timing needs to support the determination of the valid TA and support autonomous adjustment of the TA.

Optionally, in one embodiment of the present disclosure, if configured by the network, the UE can automatically adjust the TA when cell reselection occurs according to the UE function. The UE can send LS to RAN4 to inquire about the feasibility and necessary conditions for adjusting the TA. For example, it can be inquired whether the above behavior is applicable when the DL reference timing difference between the last camping cell and the current camping cell exceeds a threshold, how the UE adjusts the TA, or whether it is necessary to define additional RRM procedures to obtain the timing difference, etc.

Among them, in one embodiment of the present disclosure, the first trigger condition refers to a trigger condition that the terminal needs to meet when cell reselection occurs. The first trigger condition can be, for example, that the measurement interval between the first DL reference time Ta,old1 of the last serving cell before the terminal reselects the cell and the second DL reference time Ta,new1 of the current serving cell after the terminal reselects the cell is greater than the first interval threshold K1*, that is, Ta,new1-Ta,old1 is greater than K1*.

Wherein, Ta,new1 refers to the second DL reference time of the current serving cell, specifically, it may refer to the reference time of "(Nta+Nta_offset)*Tc" in the current serving cell. Ta,old1 refers to the first DL reference time of the last serving cell, specifically, it may refer to the reference time of "(Nta+Nta_offset)*Tc" in the last serving cell. Nta refers to the measurement value sent to the UE as part of the timing advance command. Nta_offset is a fixed value that varies according to different frequency bands and subcarrier spacings.

Among them, in one embodiment of the present disclosure, the second trigger condition refers to a trigger condition that the terminal needs to meet when no cell reselection occurs. Since the location of the UE may change over time, it is necessary to continuously maintain the terminal timing information. The second trigger condition may be, for example, that the measurement interval between the third DL reference time Ta,old2 of the last measurement time point before the terminal timing information changes and the fourth DL reference time Ta,new2 of the current measurement time point after the terminal timing information changes is greater than the second interval threshold K2*, that is, Ta,new2-Ta,old2 is greater than K2*.

The last measurement time point may be, for example, the measurement time point of the last positioning measurement before the terminal timing information changes. The third DL reference time Ta,old2 of the last measurement time point may be, for example, the DL reference time used in the positioning measurement process when the positioning measurement was last performed before the terminal timing information changed.

The current measurement time point may be, for example, the measurement time point when the terminal timing information is changed and the fourth DL reference time Ta,new2 of the current measurement time point may be, for example, the DL reference time used in the positioning measurement process when the terminal timing information is changed and the positioning measurement is currently performed.

The terminal timing information may include TA, for example. Ta,new2 refers to the fourth DL reference time of the current measurement time, and specifically refers to the reference time of "(Nta+Nta_offset)*Tc" at the current measurement time point. Ta,old2 refers to the third DL reference time of the last measurement time point, and specifically refers to the reference time of "(Nta+Nta_offset)*Tc" at the last measurement time point.

Optionally, in one embodiment of the present disclosure, the DL reference time follows the current DL timing. For example, the DL reference time may follow the DL timing of the current camping cell, the DL timing of the current serving cell, or the DL timing of the current measurement time. The "first", "second", "third", and "fourth" in the first DL reference time, the second DL reference time, the third DL reference time, and the fourth DL reference time are only used to distinguish the remaining DL reference times.

In one embodiment of the present disclosure, the first interval threshold K1* refers to the interval threshold adopted by the first trigger condition. The second interval threshold K2* refers to the interval threshold adopted by the second trigger condition. The "first" and "second" in the first interval threshold K1* and the second interval threshold K2* are only used to distinguish the other interval thresholds.

Optionally, in one embodiment of the present disclosure, the second interval threshold K2* may be determined by a threshold determining factor, for example; wherein,

Threshold determining factors may include, for example, at least one of the following:

eDRX cycle duration;

Adjustment factor N of eDRX cycle duration.

For example, in one embodiment of the present disclosure, the second interval threshold K2* may be N*eDRX, that is, N times the eDRX cycle duration. N may be, for example, a positive integer.

Optionally, in an embodiment of the present disclosure, the second interval threshold K2* may also include other factors in addition to the eDRX cycle duration and the adjustment coefficient N of the eDRX cycle duration.

Optionally, in an embodiment of the present disclosure, the UL timing refers to the timing when the SRS performs uplink transmission. The UL timing may include, for example, conditionally triggerable autonomous UL timing and conditionally untriggerable autonomous UL timing.

In one embodiment of the present disclosure, conditionally triggerable autonomous UL timing refers to a UL timing that can be autonomously adjusted by the terminal when at least one condition is met. During the adjustment process of conditionally triggerable autonomous UL timing, the terminal can, for example, maintain a positioning receive-transmit time difference measurement.

In one embodiment of the present disclosure, the condition that autonomous UL timing cannot be triggered refers to the UL timing that the terminal cannot perform autonomous adjustment when at least one condition is met. During the adjustment process of autonomous UL timing that cannot be triggered, the terminal can, for example, stop a positioning receive-send time difference measurement.

For example, in one embodiment of the present disclosure, when the terminal supports autonomous adjustment of TA and meets the SRS validity period condition, if UL timing adjustment occurs, the terminal needs to abandon the ongoing positioning reception-transmission time difference measurement.

For example, in one embodiment of the present disclosure, when the terminal supports autonomous adjustment of TA, meets the SRS validity period conditions, cell reselection occurs, and the first trigger condition is met, the terminal can continue to perform positioning reception-transmission time difference measurement even if UL timing adjustment occurs.

Optionally, in an embodiment of the present disclosure, when adjusting the UL timing, the terminal may determine a maximum time adjustment amplitude and a minimum adjustment step corresponding to the UL timing, and adjust the UL timing according to the maximum time adjustment amplitude and the minimum adjustment step.

In one embodiment of the present disclosure, the maximum time adjustment amplitude Tq refers to the maximum value to which the time amplitude of the UL timing can be adjusted. The maximum time adjustment amplitude Tq may be smaller than the amplitude threshold, for example.

In one embodiment of the present disclosure, the minimum adjustment step size Tp refers to the minimum value of the UL timing step size that can be adjusted. The minimum adjustment step size Tp, for example, needs to meet the measurement accuracy requirement. The measurement accuracy requirement, for example, can be the minimum accuracy requirement of the UL timing.

Optionally, in an embodiment of the present disclosure, when the terminal adjusts the UL timing according to the maximum time adjustment amplitude and the minimum adjustment step, the terminal may dynamically adjust the UL timing according to the maximum time adjustment amplitude and the minimum adjustment step. For example, the terminal may adjust the UL timing in the form of dynamic reduction.

For example, in one embodiment of the present disclosure, the terminal may first adjust the UL timing with 1/2Tq, and then adjust the UL timing with 1/4Tq.
