Optionally, the measurement configuration may be preconfigured by the network device to the terminal, and is used for configuring the terminal to perform carrier phase measurement, where when the terminal receives the measurement configuration, the terminal determines that it needs to perform measurement reporting of CPP, and may receive a reference signal based on the measurement configuration, so as to perform carrier phase measurement based on the reference signal. Alternatively, the measurement configuration may include a time-frequency domain position of the reference signal, etc., and the terminal may receive the reference signal based on the time-frequency domain position of the reference signal.

Optionally, the network device may send at least one reference signal to the terminal, where at least some of the reference signals may have different frequency domain locations, and optionally, the frequency domain locations may be, for example, positioning frequency layers (positioning frequency layer, PFLs), where one PFL may correspond to one or more reference signals.

Step 2102, the terminal performs carrier phase measurement based on the single measurement sample to obtain a measurement result for the single measurement sample.

Alternatively, the measurement samples may be understood as reference signals, for example, wherein at least one sampling interval may be configured for the reference signals, and the terminal may perform carrier phase measurement by measuring the reference signals in the sampling interval, which may be configured by the network device, for example, may be carried in a measurement configuration configured by the network device as described above.

Alternatively, the above-mentioned "the measurement result for a single measurement sample is obtained by performing carrier phase measurement based on a single measurement sample" can be understood as, for example: and carrying out carrier phase measurement on the reference signal in the single sampling interval to obtain a measurement result of the reference signal in the single sampling interval. Alternatively, the single sampling interval may be any sampling interval of the terminal. Alternatively, the terminal may perform measurement based on the above measurement configuration when performing carrier phase measurement on the reference signal, where the measurement configuration may include, for example, a measurement period, a measurement object (MeasObject) (i.e., a reference signal to be measured), a measurement interval configuration (MeasGapConfig), and the like.

Alternatively, the above measurement result may include, for example, at least one of:

reference Signal Carrier Phase (RSCP);

reference signal carrier phase difference (Reference signal carrier phase difference, RSCPD).

Step 2103, the terminal reports the first measurement report to the network device.

Alternatively, the terminal may report the first measurement report to the network device based on the measurement result of the single measurement sample, which may be included in the first measurement report.

Optionally, in some embodiments, when the terminal is to report the first measurement report to the network device, the terminal may first determine the accuracy of the measurement result of the single measurement sample, and further determine whether the accuracy of the measurement result of the single measurement sample meets a first condition (such as whether the accuracy is greater than a first threshold), report the first measurement report when the accuracy of the measurement result of the single measurement sample meets the first condition, and not report the first measurement report when the accuracy of the measurement result of the single measurement sample does not meet the first condition.

For example, the terminal may compare the measurement result of the single measurement sample with a predetermined ideal measurement result, determine that the accuracy of the measurement result of the single measurement sample satisfies the first condition when the difference therebetween is smaller than the first threshold, and otherwise determine that the accuracy of the measurement result of the single measurement sample does not satisfy the first condition.

As can be seen from steps 2102 and 2103, after measuring a single measurement sample to obtain a measurement result of the single measurement sample, the terminal reports the first measurement report based on the measurement result of the single measurement sample, so that in some embodiments, the time for the CPP to successfully complete the measurement and report (or referred to as the time for successfully measuring and reporting the first measurement report corresponding to the CPP) is determined based on the time required by the terminal to report the measurement of the single measurement sample. That is, when calculating the time for successful completion of measurement and reporting of CPP, the number of measurement samples N may be made _sample ＝1。

Optionally, in some embodiments, the terminal may perform some other measurements besides the carrier phase measurement, such as radio resource management (Radio Resource Management, RRM) measurement, radio link monitoring (Radio Link Monitoring, RLM) measurement, beam failure detection (Beam Failure Detection, BFD) measurement, etc., optionally, when other measurements than CPP are also performed based on a single measurement sample, the terminal may report a second measurement report while reporting the first measurement report, where the second measurement report may be: measurement reports corresponding to other measurements than CPP, the second measurement report may include, for example, a reference signal time difference (Reference Signal Time Difference, RSTD), etc.; alternatively, when other measurements than CPP are measured based on a plurality of measurement samples, the terminal may report the first measurement report and the second measurement report separately, respectively.

Step 2104, the network device performs CPP based on the first measurement report.

Alternatively, the network device may determine the location of the terminal based on the measurement results of the single measurement sample, e.g. determine an absolute location and/or a relative location, which may be, for example, the relative location of the terminal and the network device, thereby successfully implementing the CPP.

As can be seen from the foregoing, in the embodiments of the present disclosure, when a terminal performs carrier phase measurement, the terminal may measure a single measurement sample to obtain a measurement result of the single measurement sample, and may report based on the measurement result of the single measurement sample after obtaining the measurement result of the single measurement sample.

The positioning measurement reporting method according to the embodiment of the present disclosure may include at least one of step S2101 to step S2104. For example, step S2101 may be implemented as a separate embodiment, step S2102 may be implemented as a separate embodiment, and step S2101+s2102 may be implemented as a separate embodiment, but is not limited thereto.

In this embodiment mode or example, the steps may be independently, arbitrarily combined, or exchanged in order, and the alternative modes or examples may be arbitrarily combined, and may be arbitrarily combined with any steps of other embodiment modes or other examples without contradiction.

As shown in fig. 2B, an embodiment of the present disclosure relates to a positioning measurement reporting method, for use in a communication system 100, the method including:

step 2201, the network device sends a reference signal to the terminal.

A detailed description of step 2201 may be described with reference to the above embodiments.

Step 2202, the terminal performs carrier phase measurement based on the single PFL to obtain a measurement result for the single PFL.

Alternatively, the above-mentioned "carrier phase measurement based on a single PFL results in a measurement for a single PFL" can be understood as, for example: and carrying out carrier phase measurement on at least one reference signal on the single PFL to obtain a measurement result of at least one reference signal corresponding to the single PFL. Alternatively, the terminal may perform the measurement based on the measurement configuration in the embodiment of fig. 2A when performing the carrier phase measurement, and a detailed description of this part may be described with reference to the above-described embodiments.

RSCP；

RSCPD。

step 2203, the terminal reports the first measurement report to the network device.

Alternatively, the terminal may report the first measurement report to the network device based on the measurement result of the single PFL, which includes the measurement result of the single PFL.

Optionally, in some embodiments, when the terminal is to report the first measurement report to the network device, the terminal may determine the accuracy of the measurement result of the single PFL, and further determine whether the accuracy of the measurement result of the single PFL meets a second condition (e.g., whether the accuracy is greater than a second threshold), report the first measurement report when the accuracy of the measurement result of the single PFL meets the second condition, and not report the first measurement report when the accuracy of the measurement result of the single PFL is not met.

For example, the terminal may compare the measurement result of the single PFL with a predetermined ideal measurement result, determine that the accuracy of the measurement result of the single PFL satisfies the second condition when the difference therebetween is smaller than the second threshold, and otherwise determine that the accuracy of the measurement result of the single PFL does not satisfy the second condition.

As can be seen from the above steps 2202 and 2203, after measuring a single PFL, the terminal reports the first measurement report based on the measurement result of the single PFL, so that in some embodiments, the time for the CPP to successfully complete the measurement and report (or referred to as the time for successfully measuring and reporting the first measurement report corresponding to the CPP) is determined based on the time required by the terminal to report the measurement of the single PFL. That is, when calculating the time for successful completion of measurement and reporting of CPP, the total number of PFLs L may be made l=1.

Optionally, in some embodiments, the terminal may perform some other measurements besides the carrier phase measurement, such as RRM measurement, RLM measurement, BFD measurement, and so on, optionally, when other measurements besides CPP are also measurements based on a single PFL, the terminal may report a second measurement report at the same time as the first measurement report, where the second measurement report may be: measurement reports corresponding to other measurements than CPP, the second measurement report may include RSTD, for example; alternatively, when other measurements than CPP are measured based on a plurality of PFLs, the terminal may report the first measurement report and the second measurement report separately, respectively.

Step 2204, the network device performs CPP based on the first measurement report.

Alternatively, the network device may determine the location of the terminal, such as determining an absolute location and/or a relative location, which may be, for example, the relative location of the terminal and the network device, based on the measurement results of the individual PFLs, thereby successfully implementing the CPP.

As can be seen from the foregoing, in the embodiments of the present disclosure, when a terminal performs carrier phase measurement, the terminal may measure a single PFL to obtain a measurement result of the single PFL, and may report based on the measurement result of the single PFL after obtaining the measurement result of the single PFL.

For example, step S2201 may be implemented as an independent embodiment, step S2202 may be implemented as an independent embodiment, and step s2201+s2202 may be implemented as an independent embodiment, but is not limited thereto.

In some embodiments, the method may include the method described in the embodiments of the communication system side, the terminal side, the network device side, and so on, which are not described herein.

The positioning measurement reporting method according to the embodiments of the present disclosure may include at least one of step S5101 to step S5102. For example, step S5101 may be implemented as an independent embodiment, and step S5102 may be implemented as an independent embodiment, but is not limited thereto.

The following is an exemplary description of the above method.

In the previous RAN1 conference, both parties agree to introduce two NR carrier phase location measurements (RSCP and RSCPD).

Alternatively, the downlink RSCPD measurement period requires:

FFS the same requirements should apply to DL RSCP/RSCPD and related legacy measurements when reported together with legacy positioning measurements.

Whether the FFS re-uses existing Rel-17 requirements or not, based on RAN 1's discussion of CPP measurement time window.

In general, if CPP measurements are reported together with other legacy measurements, the existing legacy reporting delay requirement (reporting delay requirements, i.e., the time to successfully measure and report the first measurement report corresponding to the CPP described above) of UE (i.e., the aforementioned terminal) PRS (i.e., the aforementioned reference signal) measurements can be reused for CPP measurements.

For example, if RSCPD needs to be reported with RSTD that provides an integer portion of the ToA estimate, the same existing measurement reporting delay requirements should apply to both.

In RANs 4#108, the following protocol is achieved:

RSCP/RSCPD is reported with other positioning measurements, the same measurement period requirements (i.e. Rx-Tx time difference/RSTD measurements) should apply.

FFS-whether the existing Rx-Tx time difference/RSTD measurement period applies RSCP/RSCPD is not explicitly used when reporting with other positioning measurements.

Therefore, a detailed measurement method of CPP of the UE will be further decided.

Example 1: UE CPP measurement based on single sample (single sample).

At the RAN1 conference, the following protocol is achieved.

Each DL RSCP/RSCPD measurement instance is obtained by means of a sample only.

From the perspective of RAN4 RRM, the CPP requirements should be based on only a single sample. Therefore, we can also propose:

the requirements of the proposed 1 dl RSCP/RSCPD, including measurement report delay (measurement reporting delay) and accuracy (accuracy), should be defined by only a single sample.

Example 2: UE CPP measurement based on single PFL.

At the same time, RAN1 also agrees to:

when DL RSCPD/RSCP measurements are reported with DL RSTD/UE Rx-Tx time difference measurements, DL RSCPD/RSCP measurements are obtained from only a single DL PFL.

Alternatively, from the RAN1 point of view, the reporting of carrier phase measurements from one DL PFL has no impact on the reporting of DL RSTD and/or UE Rx-Tx time difference measurements from the same DL PFL or other DL PFLs.

However, in existing (e.g., current in current 38.133), the requirements of other PRS measurements are applicable to multiple PFLs. For example

i is an index of the positioning frequency layer.

Alternatively, if the total measured positioning frequency layer number is 1, the current existing requirements (i.e., the above equation) can be reused for RSCP/RSCPD.

Thus, we can propose:

proposal 2 rscp/rsdp measurement report period requirements may be defined as:

i is an index to locate the frequency layer,

l is the total number of positioning frequency layers, L being equal to 1 for RSCP/RSCP requirements.

Alternatively, when introducing single sample (single sample) based UE CPP measurements, single PFL based UE CPP measurements, the affected specifications in the existing protocol (TS 33.133 v 18.2.0) may be:

when the physical layer receives the last of the NR-TDOA-ProvidAlsitostata message and the NR-TDOA-RequestLocationInformation message from the LMF through the LPP, the UE should be able to measure a plurality of DL RSCP/RSCDP measurements within a measurement period as defined below:

wherein i is an index of a positioning frequency layer;

l is the total number of positioning frequency layers, L is "1" if the requirements apply only to RSCP/RSCPD measurements (i.e., CPP measurements) in Rel 18;

T _effect,i is a measurement period of PRS RSCP/RSCDP measurement in the positioning frequency layer i;

T _RSTD,i time required for measurement of PRS RSCP/RSCP measurements in positioning frequency layer i: the definition is as follows:

wherein N is _RxBeam,i Is the UE Rx beam scanning factor. In FR 1N _RxBeam,i =1; in FR2, if the UE supports the capability of locating the frequency band of frequency layer i, N _RxBeam,i Equal to the value reported by the UE in supplantedloweRxBeamSweeptingfactor-FR 2, and the LMF indicates the value of lowerRxBeamSweeptinfactor-FR 2 in NR-TDOA-request location information, otherwise N _RxBeam,i Equal to 8;

N _TEG,i Is carried out by NR-DL-TDOA-RequestLocationInformationMessassame DL-PRS-resource ewithdiffeentxtegs-r 17[34 ]]Indicated number of Rx TEGs requesting UE to measure PRS resources, and in case of indication "N0", N _TEG,i Is the maximum number of Rx TEGs that the UE can support to measure the same PRS resources reported in NR-UE-TEG-Capability.

k _TEG,simul,i Is the number of Rx TEGs that the UE can measure simultaneously, k _TEG,simul,i May be reported by means of measures MDL-PRS-resource ewithdiffertextgssimul.

K _p,PRS,i Is the scaling factor of the positioning frequency layer to be measured in the relevant measurement gap mode, which is defined as K for UEs configured with concurrent measurement gaps (concurrent measurement gap) _p,PRS,i ＝N _total /N _available The method comprises the steps of carrying out a first treatment on the surface of the For UEs not configured with concurrent measurement gaps, it is defined as K _p,PRS,i ＝1；

For the duration of maximum (T _PRS,i Mgrp_max), where mgrp_max is the maximum MGRP per UE MG and per FR MG for all configurations within the same frequency range as the positioning frequency layer, and starting from any associated gap occasion that covers PRS occasions:

N _total is the total number of relevant gap opportunities covering PRS opportunities within a window, includingDiscarded and non-discarded instances of intra-window correlation measurement gaps

N _available The number of non-discarded relevant gap occasions covering PRS occasions within window W after further considering MG collisions by applying the selected gap collision rule;

if N _available =0, then the requirement is inapplicable;

is the maximum number of DL PRS resources in the positioning frequency layer I configured in one slot;

L _{available_PRS,i} is at _{Tavailable_PRS,i} Duration of available PRS in positioning frequency layer i to be measured during; in the same way as PRS duration K defined in the existing protocol. For L _{available_PRS,i} Only PRS resources that are not muted and that overlap completely or partially with the MG are considered;

N _sample is the number of PRS measurement samples, where

N in the following cases _sample ＝1：

If the UE supports supported dl-PRS-processing samples and the LMF requests the UE to perform positioning measurements with a reduced number of samples, the following condition is satisfied:

PRS bandwidth is within active BWP, and

the difference amplitude between the SS-RSRP of the serving cell and the PRS-RSRP of the neighboring cell is within 6 dB.

And if the target of the measurement is RSCP/RSCPD

N in the following cases _sample ＝2：

If the UE supports supported dl-PRS-processing samples and the LMF requests the UE to perform positioning measurements with a reduced number of samples, the following condition is not satisfied:

PRS bandwidth is within active BWP, and

Otherwise, N _sample ＝4。
