For downlink positioning techniques, the gNB needs to send positioning reference signals (Positioning Reference Signal, PRS).

In Release 18, R18, carrier phase positioning (Carrier Phase Positioning, CPP) techniques are introduced, i.e. the UE may measure DL reference signal carrier phase difference (Reference Signal Carrier Phase difference, RSCPD) based on DownLink (DL) Positioning Reference Signals (PRS) and/or reference signal carrier phase (Reference Signal Carrier Phase, RSCP) and the gNB may measure UL RSCP based on UpLink (UP) positioning reference signals (SRS).

In order to improve positioning accuracy, for example, to eliminate the whole-cycle ambiguity of CPP measurement, the LMF may configure a measurement time window for the UE or the gNB or the PRU, so that the UE and the PRU measure PRS in the same time window, or so that different gnbs measure SRS in the same time window.

In some embodiments, the first measurement is a positioning measurement other than the measurement of the carrier phase positioning CPP.

The specific implementation manner of the first type of measurement refers to the related description of the optional implementation manner of step S2102, which is not described herein.

In some embodiments, if the first entity 102 does not indicate to the first device 101 whether to perform the first type of measurement on the positioning reference signal within a time window, the first device 101 may determine whether to perform the first type of measurement on the positioning reference signal within the time window according to a protocol convention.

In some embodiments, the first device 101 may also determine whether to perform a first type of measurement on the positioning reference signal within the time window based on configuration information of the first device 101 itself.

In step S2203, the first device 101 performs positioning reference signal measurement, and obtains all measurement results.

In some embodiments, if the first device determines to perform measurement of the positioning reference signal within a time window to obtain the first measurement result, the first device may perform measurement of the positioning reference signal within the time window to obtain all measurement results requested by the first entity.

In some embodiments, the first entity 102 requests the first device 101 to report RSCPD, RSRP, and the first device determines to measure the positioning reference signal in the time window based on the protocol convention (or the configuration information) to obtain the first measurement result, and then the first device 101 may measure SRS or PRS in the time window to obtain RSCPD and RSRP.

As shown in fig. 2C, an embodiment of the present disclosure relates to a method for measuring a positioning reference signal, where the method includes:

In step S2301, the first entity 102 sends a first message to the first device 101.

In step S2302, in the case of multiple time windows, the first entity 102 determines an association relationship between the time window and the measurement result.

The association relationship between the time window and the measurement result may also be referred to as a time window associated measurement result, or a time window associated with the measurement result, or the like, which is not limited in this disclosure.

In some embodiments, the measurement comprises a first measurement and/or a measurement of CPP.

In some embodiments, the first entity 102 may associate at least one time window for each measurement. For example, the first entity 102 configures the first device 101 with a time window #1, a time window #2, and a time window #3, and the measurement results requested by the first entity 102 are RSTD, rx-Tx time difference, RSCP. The first entity 102 may associate RSTD with time window #1, rx-Tx time difference with time window #2, RSCP with time window # 3.

In step S2303, the first entity 102 sends a third message to the first device 101.

In some embodiments, the third message may be the same message as the first message, that is, the third message is a time window configuration message, which may include an associated measurement for each time window, etc., which is not limited by the present disclosure.

For example, the first entity 102 configures the first device 101 with the time window #1, the time window #2 through the first message (the third message), and indicates that the association measurement result of the time window #1 is RSCP and the association measurement result of the time window #2 is RSRP in the first message.

In some embodiments, if the third message indicates the association between the time window and the measurement result, the first device 101 may determine, according to the third message, the association between the time window and the measurement result, and perform positioning reference signal measurement within the time window, to obtain the associated measurement result.

In some embodiments, if the third message does not indicate a time window associated with the first measurement result, the first device 101 will not perform positioning reference signal measurements resulting in the first measurement result within the time window. For example, when the first entity 102 does not configure a time window for RSTD, then the first device 101 may not need to make measurements to obtain RSTD within the time window.

In some embodiments, if the third message does not indicate the association between the time window and the measurement result, but requests the measurement result of the first device 101 to report, the first device 101 may determine the association between the time window and the measurement result according to a protocol convention, or configuration information of the first device 101 itself.

In step S2305, the first device 101 sends a fourth message to the first entity 102.

For a detailed description of step S2305, reference may be made to step S2105 and/or step S2205 described above.

Fig. 5 is an interactive schematic diagram illustrating a measurement method of a positioning reference signal according to an embodiment of the present disclosure. As shown in fig. 5, an embodiment of the present disclosure relates to a measurement method of a positioning reference signal, for a positioning system including a first device and a first entity, the method including:

in step S5101, the first entity 102 sends a first message to the first device 101.

In step S5102, the first device 101 determines whether a first type of measurement is performed on the positioning reference signal within the time window.

A detailed description of steps S5101-S5102 may be described with reference to the above embodiments.

In this embodiment, after the first entity indicates the positioning reference signal measurement time window to the first device, the first device determines whether to perform a first type of measurement on the positioning reference signal within the time window. Thereby, the efficiency of communication system positioning is improved.

The following is an exemplary description of the above method.

The method for solving the problem of how to restrict the traditional measurement behavior after the time window is configured comprises the following optional implementation scheme:

the embodiment of the disclosure relates to a measurement method of a positioning reference signal, taking a first device as a terminal UE or PRU or gNB as an example, the method comprises:

if a time window is configured, the time window may be applicable to CPP and other conventional measurements (e.g., rx-Tx moveout, RSRP, RSRPP).

If a time window is configured, the time window may be applicable to the CPP and the LMF may indicate whether it is used for traditional measurements (additional indication). If the LMF has no additional indication, the time window is only used for CPP related measurements or it is decided by the UE or the gNB whether the time window is used for legacy measurements.

If a time window is configured, the LMF may indicate which measurement the time window applies to, including CPP and legacy measurements. If the LMF does not indicate, then the UE or gNB decides whether to use the time window.

1. When the LMF configures the UE or PRU or gNB with a time window, the time window is used to instruct the UE or PRU or gNB to measure the positioning reference signal in the time window.

The UE or PRU (equivalent to the measurement behaviour of a protocol-agreed UE or PRU) measures PRS over a given time window, resulting in all measurements requested by the LMF. For example, the LMF requests the UE to report RSCPD, rx-Tx time difference, then the UE may measure PRS within a time window, resulting in RSCPD and Rx-Tx time difference.

gNB measures SRS in a given time window, yielding all measurements requested by LMF. For example, if the LMF requests that the gNB report RSCPD, rx-Tx time difference, the gNB may measure SRS during the time window to obtain RSCPD and Rx-Tx time difference.

The UE or PRU measures PRS in a given time window to obtain CPP related measurement results, such as RSCPD and RSCP, and can determine whether to measure PRS in the time window according to the indication of LMF to obtain measurement results beyond CPP, such as LMF indicates whether the UE or PRU measures PRS in the time window to obtain Rx-Tx time difference.

5. Based on 4, if there is no such indication, the UE or PRU determines whether to measure PRS in a time window based on the implementation, resulting in a measurement result other than CPP.

The gNB measures the SRS in a given time window to obtain measurement results related to CPP, such as RSCPD and RSCP, and can determine whether to measure the SRS in the time window according to the indication of LMF to obtain measurement results beyond CPP, such as LMF indicates whether gNB measures the PRS in the time window to obtain Rx-Tx time difference.

7. Based on 6, if there is no such indication, the gNB determines, based on implementation, whether to measure SRS in a time window, resulting in a measurement result other than CPP.

Lmf may indicate to UE/PRU/gNB the measurement results of the time window application, including CPP related measurement results and positioning measurement results other than CPP. If the LMF does not have the indication, the UE/PRU/gNB can determine, based on implementation, what measurement results to apply.

The lmf may request the UE/PRU/gNB to report the measurements and configure a time window for each measurement, i.e. each measurement may be associated with 1 or more time windows. For example, RSTD corresponds to time window 1, rx-Tx time difference corresponds to time window 2, and RSCP corresponds to time window 3. If the LMF does not configure a time window for a certain measurement result, the UE/PRU/gNB does not need to make measurements in that time window (the time window configured for other measurement results).

10. The indication may be sent by an LPP message (LPP location information request) message or an NRPPa message (measurement request).

The embodiments of the present disclosure also provide an apparatus for implementing any of the above methods, for example, an apparatus is provided, where the apparatus includes a unit or a module for implementing each step performed by the terminal in any of the above methods.
