The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0142] In some embodiments, the first device 101 may also be a positioning reference unit (PRU).

[0143] In some embodiments, the first entity 102 may be a core network device. The first entity 102 may be a single device, multiple devices, or a group of devices. The first entity 102 may be virtual or physical. The core network, for example, includes at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0144] In some embodiments, the first entity 102 may be, for example, a location management function (LMF) network element; the first entity 102 may also be an access and mobility management function (AMF) network element.

[0145] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0146] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0147] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods.

[0148] 5G NR introduces multiple positioning technologies to accurately locate the UE. For uplink positioning and hybrid uplink and downlink positioning, the gNB configures the UE with an uplink positioning reference signal (PRS). The UE then transmits an uplink PRS, such as a Sounding Reference Signal (SRS), based on the PRS configuration. For downlink positioning, the gNB also transmits a Positioning Reference Signal (PRS).

[0149] Release 18 (R18) introduces carrier phase positioning (CPP) technology. The UE can measure the downlink reference signal carrier phase difference (RSCPD) and / or reference signal carrier phase (RSCP) based on the downlink (DL) positioning reference signal (PRS), and the gNB can measure the uplink (UL) RSCP based on the uplink (UL) positioning reference signal (SRS).

[0150] To improve positioning accuracy, for example, to eliminate the integer ambiguity of CPP measurement, the LMF can configure a measurement time window for the UE, gNB, or PRU, so that the UE and PRU measure PRS in the same time window, or different gNBs measure SRS in the same time window.

[0151] FIG2A is an interactive diagram illustrating a method for measuring a positioning reference signal according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a method for measuring a positioning reference signal, the method comprising:

[0162] In some embodiments, the second message is used to configure one or more time windows for the first device 101 .

[0163] In some embodiments, the multiple time windows are used to instruct the first device 101 to measure the positioning reference signal in the time window, or to request the first device 101 to measure the positioning reference signal in multiple time windows.

[0164] In some embodiments, the name of the second message is not limited, for example, it can be a first indication message, a time window indication message, etc.

[0165] In some embodiments, if the first device 101 is a UE or a PRU, the second message may be a Long Term Evolution Positioning Protocol (LPP) message, such as an LPP request location information message.

[0166] In some embodiments, if the first device 101 is an access network device, the second message may be a New Radio Positioning Protocol A (NRPPa) message, for example, an NRPPa measurement request message.

[0167] In some embodiments, the first device 101 receives the second message sent by the first entity 102 .

[0168] Step S2102 : The first entity 102 sends a first message to the first device 101 .

[0169] In some embodiments, the name of the first message is not limited, for example, it can be a first indication message, measurement indication information, etc.

[0170] In some embodiments, if the first device 101 is a UE or a PRU, the first message may be a Long Term Evolution Positioning Protocol (LPP) message, such as an LPP request location information message.

[0171] In some embodiments, if the first device 101 is an access network device, the first message may be a New Radio Positioning Protocol A (NRPPa) message, for example, an NRPPa measurement request message.

[0172] In some embodiments, the first message may be used to instruct the first device 101 on how to measure the positioning reference signal based on multiple time windows to obtain a positioning reference signal measurement result.

[0173] In some embodiments, the positioning reference signal measurement result may include a first measurement result of carrier phase positioning (CPP).

[0174] In some embodiments, the first message may be used to instruct the first device 101 to measure a positioning reference signal based on multiple positioning reference signal measurement time windows and report the positioning reference signal measurement result.

[0175] For example, if the first device 102 is configured with two time windows, the first message can instruct the first device to measure the positioning reference signal in the two time windows respectively, and obtain a positioning reference signal measurement result corresponding to each time window, that is, obtain two positioning reference signal measurement results.

[0176] In some embodiments, the first measurement result may be at least one of a reference signal carrier phase (RSCP), a reference signal carrier phase difference (RSCPD), etc. This disclosure is not limited thereto.

[0177] In some embodiments, after the first entity 102 sends the first message to the first device 101, the first device 101 may receive the first message and, based on the instructions in the first message, determine a measurement behavior for the positioning reference signal based on multiple time windows. For example, the positioning reference signal may be measured based on each time window to obtain a positioning reference signal measurement result corresponding to each time window; or the positioning reference signal may be measured based on a specified time window among the multiple time windows to obtain a positioning reference signal measurement result corresponding to the specified time window, etc., which are not limited in this disclosure.

[0178] In some embodiments, when the first device 101 is a UE or a PRU, the first device 101 can determine the measurement behavior of the PRS based on multiple time windows based on the first message; when the first device 101 is an access network device, the first device 101 can determine the measurement behavior of the SRS based on multiple time windows based on the first message.

[0179] In some embodiments, if the first message indicates that the measurement behavior is to measure the positioning reference signal in each time window, then after the UE or PRU receives the first message, it measures the PRS in each time window and obtains a positioning reference signal measurement result corresponding to each time window; after the access network device receives the first message, it measures the SRS in each time window and obtains a positioning reference signal measurement result corresponding to each time window.

[0180] In some embodiments, the second message and the first message may be the same message, for example, both are time window configuration messages, etc., which is not limited in the present disclosure.

[0181] In the embodiment of the present disclosure, step S2101 can be executed simultaneously with step S2102, and the present disclosure does not limit this.

[0182] Step S2103: When the first message indicates that a measurement result is associated with a time window, the first device 101 performs positioning reference signal measurement in each time window to obtain a measurement result corresponding to each time window.

[0183] In some embodiments, after receiving the first message sent by the first entity 102 , the first device 101 may determine how to measure the positioning reference signal based on multiple time windows and obtain a positioning reference signal measurement result.

[0184] In some embodiments, the first message instructs the first device 101 to report a positioning reference signal measurement result for each time window. The first message indicates that a positioning reference signal measurement result is associated with a time window, or the first message indicates that a time window is associated with a positioning reference signal measurement result.

[0185] In some embodiments, a positioning reference signal measurement result corresponding to a time window may be a first measurement result of a CPP corresponding to each time window, for example, each time window corresponds to an RSCP and an RSCPD; or, each time window corresponds to an RSCP; or, each time window corresponds to an RSCPD, etc.

[0186] In some embodiments, the positioning reference signal measurement result may further include a second measurement result of other positioning reference signal measurements except the CPP.

[0187] In some embodiments, the second measurement result may also be referred to as other positioning measurement results, which is not limited in this disclosure.

[0188] In some embodiments, a positioning reference signal measurement result corresponding to a time window may be a first measurement result and a second measurement result corresponding to each time window; or, a first measurement result and multiple second measurement results corresponding to a time window may be, and the present disclosure does not limit this.

[0189] For example, a positioning reference signal measurement result corresponding to a time window may be an RSCP and an RSRP corresponding to a time window; or it may be an RSCP, an RSCPD, a reference signal received power (RSRP), and a reference signal time difference (RSTD) corresponding to a time window, etc., which is not limited in this disclosure.

[0190] In some embodiments, if the first device 101 is a UE or a PRU, the first device 101 may measure the PRS in each time window and obtain a positioning reference signal measurement result corresponding to each time window.

[0191] For example, the first entity 102 configures two time windows and requests the UE or PRU to measure the PRS in the time windows to obtain the RSCP. Then, the UE or PRU measures the PRS in the two time windows and obtains two RSCP values.

[0192] In some embodiments, if the first device 101 is an access network device, the first device 101 measures a channel sounding reference signal (SRS) in each time window, and obtains a positioning reference signal measurement result corresponding to each time window.

[0193] For example, the first entity 102 configures two time windows and requests the access network device to measure the SRS in the time windows to obtain the RSCP. Then, the access network device measures the SRS in the two time windows and obtains two RSCP values.

[0194] In some embodiments, if the first device 101 is a UE or a PRU, the second measurement result may be UE Rx-Tx time difference, RSTD, PRSRSRP, PRS-path reference signal receiving power (Reference Signal Receiving Path Power, RSRPP), etc., which is not limited in this disclosure.

[0195] In some embodiments, when the first device 101 is an access network device, the second measurement result may be UL uplink relative arrival time (UpLink Relative Time of Arrival, UL-RTOA), UL arrival angle (Angle of Arrival, AOA), SRS-RSRPP, gNBRx-TX, time difference, etc., which is not limited in this disclosure.

[0196] Step S2104 : The first device 101 sends a third message to the first entity 102 .

[0197] In some embodiments, the name of the third message is not limited, for example, it can be a measurement result reporting message, a measurement result reporting request message, etc.

[0198] In some embodiments, if the first device 101 is a UE or a PRU, the third message may be a Long Term Evolution Positioning Protocol (LPP) message, such as "LPP request location information".

[0199] In some embodiments, if the first device 101 is an access network device, the third message may be a New Radio Positioning Protocol A (NRPPa) message, for example, an NRPPa measurement report message.

[0200] In some embodiments, the third message is used to report the measurement result to the first entity 102 .

[0201] The third message may include the measurement result and / or a time window associated with the measurement result.

[0202] In some embodiments, the first message indicates the relationship between the positioning reference signal measurement result and the time window, and the first device 101 may send the measurement result to the first entity 102 only through the third message to reduce signaling overhead.

[0203] In some embodiments, the first message does not indicate the relationship between the positioning reference signal measurement result and the time window. In order to ensure that the first entity 102 understands the positioning reference signal measurement result consistently with the first device 101, the first device 101 may also report the time window associated with the positioning reference signal measurement result to the first entity 102 when reporting the positioning reference signal measurement result.

[0204] In some embodiments, the third message may include a time window associated with each measurement result.

[0205] In some embodiments, the time window associated with the positioning reference signal measurement result may be used to indicate the time window in which the first device 101 measures the positioning reference signal to obtain the measurement result.

[0206] In some embodiments, the positioning reference signal measurement result may be associated with an identity document (ID) of a time window, or an index of a time window, which is not limited in the present disclosure.

[0207] For example, the first entity 102 configures three time windows for the first device 101 via a second message: time window #1, time window #2, and time window #3. The first message does not indicate the relationship between the time windows and the positioning reference signal measurement results. First device 101 determines, based on protocol agreement or its own policy, that time window #1 is associated with the measurement result RSCP, time window #2 is associated with the measurement result RSRP, and time window #3 is associated with the measurement result RSTD. After obtaining the positioning reference signal measurement results, first device 101 can report the measurement results RSCP, RSRP, and RSTD to the first entity 102 via a third message. The third message also indicates that the time window associated with RSCP is time window #1, the time window associated with RSRP is time window #2, and the time window associated with RSTD is time window #3.

[0208] In some embodiments, the first entity 102 receives the third message sent by the first device 101 .

[0209] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, step S2103 may be implemented as an independent embodiment, steps S2101+S2102+S2103 may be implemented as an independent embodiment, and steps S2102+S2103 may be implemented as a separate embodiment, but the present invention is not limited thereto.

[0210] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0211] In the disclosed embodiments, when a first entity configures multiple positioning reference signal (PRS) measurement time windows for a first device and indicates to the first device that a PRS measurement result is associated with a time window, the first device can measure and report the PRS based on the first entity's instructions. This ensures that, when the first device is configured with multiple time windows, the first device and the first entity have a consistent understanding of the use of the multiple time windows, thereby ensuring a consistent understanding of the PRS measurement results between the first device and the first entity, thereby improving the accuracy and reliability of positioning in the communication system.

[0212] FIG2B is an interactive diagram of a positioning reference signal measurement method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a positioning reference signal measurement method, the method comprising:

[0213] Step S2201: The first entity 102 sends a second message to the first device 101.

[0214] The second message is used to configure one or more time windows for the first device 101.

[0215] Step S2202 : The first entity 102 sends a first message to the first device 101 .

[0216] For a detailed introduction to steps S2201-S2202, please refer to the above steps S2101-S2102.

[0217] Step S2203: When the first message indicates that one measurement result is associated with multiple time windows, the first device 101 performs positioning reference signal measurement in each of the multiple time windows to obtain multiple first measurement results.

[0218] In some embodiments, after the first entity 102 sends the first message, the first device 101 can receive the first message and, based on the first message, determine that the first device 101 needs to perform positioning reference signal measurement in each time window of multiple time windows to obtain multiple first measurement results.

[0219] In some embodiments, the first message instructs the first device 101 to report one positioning reference signal measurement result for multiple time windows. The first message indicates that one positioning reference signal measurement result is associated with multiple time windows, or the first message indicates that multiple time windows are associated with one positioning reference signal measurement result.

[0220] In some embodiments, a positioning reference signal measurement result corresponding to multiple time windows may be a first measurement result of a CPP corresponding to multiple time windows, such as a RSCP and a RSCPD corresponding to multiple time windows; or, a RSCP corresponding to multiple time windows; or, a RSCP corresponding to multiple time windows; or, a RSCPD corresponding to multiple time windows, etc.

[0221] In some embodiments, a positioning reference signal measurement result corresponding to multiple time windows may be a first measurement result and a second measurement result corresponding to multiple time windows; or, a first measurement result and multiple second measurement results corresponding to multiple time windows, and so on. This disclosure does not limit this.

[0222] For example, a positioning reference signal measurement result corresponding to multiple time windows may be one RSCP and one RSRP corresponding to multiple time windows; or one RSCP, one RSCPD, one RSRP and one RSTD corresponding to multiple time windows, etc., which is not limited in this disclosure.

[0223] In some embodiments, the first device 101 may report any one of the first measurement results measured based on multiple time windows and the second measurement result to the first entity 102 .

[0224] In some embodiments, if the first device 101 is a UE or a PRU, the first device 101 may measure the PRS in each time window to obtain multiple RSCPs, and report any one RSCP together with other positioning reference signal measurement results to the first entity 102 .

[0225] In some embodiments, if the first device 101 is an access network device, the first device 101 measures the SRS in each time window to obtain multiple RSCPs, and reports any RSCP together with other positioning reference signal measurement results to the first entity 102 .

[0226] Step S2204: Perform positioning reference signal measurement in multiple time windows to obtain a second measurement result.

[0227] In some embodiments, the reported positioning reference signal measurement result also includes a second measurement result of other positioning reference signal measurements except the CPP.

[0228] In some embodiments, the second measurement result may be other positioning measurement results in addition to the first measurement result of the CPP.

[0229] In some embodiments, the first device 101 may perform positioning reference signal measurement in each of a plurality of time windows to obtain a result other than the CPP corresponding to each time window, and then average or fuse the plurality of results other than the CPP to obtain a second measurement result.

[0230] For example, the first device performs positioning reference signal measurement in each time window to obtain an RSRP corresponding to each time window, then averages the RSRPs corresponding to multiple time windows to obtain an average RSRP, and uses the average RSRP as the second measurement result.

[0231] In some embodiments, the first message may instruct the first device 101 to perform positioning reference signal measurements within multiple time windows to obtain a first measurement result; or, the first message may also instruct the first device 101 to perform positioning reference signal measurements within multiple time windows to obtain a first measurement result and a second measurement result, and so on. This disclosure is not limited to this.

[0232] In some embodiments, the first device 101 may also determine to perform positioning reference signal measurement within multiple time windows according to a protocol agreement or its own policy to obtain a second measurement result.

[0233] In some embodiments, when the first device 101 is a UE or a PRU, the first device 101 performs positioning reference signal measurement in each time window of multiple time windows, and the second measurement result obtained may be UE Rx-Tx time difference, RSTD, PRSRSRP, PRS-path reference signal receiving power (Reference Signal Receiving Path Power, RSRPP), etc., which is not limited in this disclosure.

[0234] In some embodiments, when the first device 101 is an access network device, the first device 101 measures the positioning reference signal within the time window, and the second measurement result obtained may be UL uplink relative arrival time (UpLink Relative Time of Arrival, UL-RTOA), UL arrival angle (Angle of Arrival, AOA), SRS-RSRPP, gNBRx-TX, time difference, etc., which is not limited in this disclosure.

[0235] In some embodiments, the second measurement result may include a measurement result corresponding to each measurement type. That is, the second measurement result may include one or more measurement results of different types. For example, the second measurement result obtained by the UE may include a UE ERx-Tx time difference; or the second measurement result obtained by the UE may include a UE ERx-Tx time difference and an RSRP, where the UE ERx-Tx time difference and the RSRP are obtained based on measurements in all time windows.

[0236] In some embodiments, the first device 101 may perform positioning reference signal measurements in multiple time windows to obtain a first measurement result and a second measurement result, and report the first measurement result and the second measurement result together to the first entity 102 .

[0237] In some embodiments, if the first message does not indicate the relationship between the time window and the second measurement result, and the first device 101 determines based on the protocol and its own policy that the second measurement result will not be obtained within multiple time windows, then the first device 101 can measure outside the multiple time windows to obtain the second measurement result, and report the first measurement result together with the second measurement result.

[0238] For example, if the first device 101 determines not to obtain the second measurement result within multiple time windows, the first device may measure the SRS or PRS within other time periods to obtain the second measurement result such as the Rx-Tx time difference.

[0239] Step S2205: The first device 101 sends a third message to the first entity.

[0240] The third message includes the measurement result and / or a time window associated with the measurement result.

[0241] In some embodiments, the first message indicates the relationship between the measurement result and the time window, and the first device 101 may send the measurement result to the first entity 102 only through the third message to reduce signaling overhead.

[0242] In some embodiments, the first message does not indicate the relationship between the measurement result and the time window. In order to ensure that the first entity 102 understands the measurement result consistently with the first device 101, the first device 101 may also report the time window associated with the measurement result to the first entity 102 when reporting the measurement result.

[0243] The communication method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2205. For example, step S2202 can be implemented as an independent embodiment, step S2203 can be implemented as an independent embodiment, step S2201+S2202+S2203+S2205 can be implemented as an independent embodiment, and step S2202+S2203+S2204 can be implemented as a separate embodiment, but the present invention is not limited thereto.

[0244] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0245] In the disclosed embodiments, when a first entity configures multiple positioning reference signal (PRS) measurement time windows for a first device and indicates to the first device that a PRS measurement result is associated with multiple time windows, the first device can measure and report PRS based on the first entity's instructions. This ensures that, when the first device is configured with multiple time windows, the first device and the first entity have a consistent understanding of the use of the multiple time windows, thereby ensuring a consistent understanding of the PRS measurement results between the first device and the first entity, thereby improving the accuracy and reliability of positioning in the communication system.

As shown in FIG2C , an embodiment of the present disclosure relates to a method for measuring a positioning reference signal, the method comprising:

[0247] Step S2301: The first entity 102 sends a second message to the first device 101.

[0248] The second message is used to configure one or more time windows for the first device 101.

[0249] Step S2302 : The first entity 102 sends a first message to the first device 101 .

[0250] For a detailed description of steps S2301 and S2302, please refer to the above steps S2101 and S2102.

[0251] Step S2303: The first device 101 selects at least one target time window from the multiple time windows.

[0252] In some embodiments, the first message may indicate that one positioning reference signal measurement result is associated with at least one target time window. The first message may indicate that at least one target time window is associated with one positioning reference signal measurement result.

[0253] In some embodiments, a positioning reference signal measurement result corresponding to at least one target time window may be a first measurement result of a CPP corresponding to at least one target time window, for example, at least one target time window corresponds to an RSCP and an RSCPD; or, at least one target time window corresponds to an RSCP; or, at least one target time window corresponds to an RSCPD, etc.

[0254] In some embodiments, a positioning reference signal measurement result corresponding to at least one target time window may be a first measurement result and a second measurement result corresponding to at least one target time window; or, it may be a first measurement result and multiple second measurement results corresponding to at least one target time window, and so on. This disclosure is not limited to this.

[0255] For example, a positioning reference signal measurement result corresponding to at least one target time window may be an RSCP and an RSRP corresponding to at least one target time window; or it may be an RSCP, an RSCPD, an RSRP and an RSTD corresponding to at least one target time window, etc., which is not limited in this disclosure.

[0256] In some embodiments, the first device may select at least one target time window from a plurality of time windows based on an instruction of the first message.

[0257] In some embodiments, the first entity 102 may indicate the target time window through the first message, for example, indicating the ID or index of the target time window. Then, the first device 101 may select at least one target time window from the multiple time windows according to the instruction of the first message.

[0258] In some embodiments, based on a policy of the first device 101 , at least one target time window is selected from a plurality of time windows.

[0259] In some embodiments, if the first message does not indicate a target time window, the first device 101 may select at least one target time window based on a policy.

[0260] In some embodiments, the policy of the first device 101 may be to select at least one target time window based on a preset window interval.

[0261] For example, the multiple time windows indicated in the second hour are time window 1, time window 2, time window 3, and time window 4. If the preset window interval is 1 time window, the target time window can include time window 1 and time window 3; if the preset window interval is 2 time windows, the target time window can include time window 1 and time window 4.

[0262] In some embodiments, the strategy of the first device 101 may be to randomly select a preset number of time windows as target time windows based on the number of time windows indicated by the second message, wherein the preset number is less than or equal to the number of time windows indicated by the second message.

[0263] In some embodiments, the first device 101 may select at least one target time window from multiple time windows based on a protocol agreement.

[0264] Step S2304: Perform positioning reference signal measurement within at least one target time window to obtain a measurement result.

[0265] In some embodiments, after determining at least one target time window, positioning reference signal measurement is performed on each target time window within the at least one target time window to obtain a positioning reference signal measurement result corresponding to the at least one target time window.

[0266] In some embodiments, if the first device 101 is a UE or a PRU, the first device 101 may measure the PRS in each target time window within at least one target time window to obtain a positioning reference signal measurement result.

[0267] In some embodiments, if the first device 101 is an access network device, the first device 101 may measure the SRS in each target time window within at least one target time window to obtain a positioning reference signal measurement result.

[0268] In some embodiments, if the first device 101 is a UE or a PRU, the first device 101 may measure the PRS in each target time window within at least one target time window to obtain at least one RSCP, and use any one of the at least one RSCP as the first measurement result.

[0269] In some embodiments, if the first device 101 is an access network device, the first device 101 measures the SRS in each target time window within at least one target time window to obtain at least one RSCP, and uses any one of the at least one RSCP as the first measurement result.

[0270] In some embodiments, the first device 101 may perform positioning reference signal measurement in each target time window of at least one target time window to obtain a second measurement result corresponding to each target time window, and then use the average value of the second measurement results corresponding to at least one target time window as a second measurement result corresponding to at least one target time window.

[0271] In some embodiments, the first message may instruct the first device 101 to perform positioning reference signal measurement within at least one target time window to obtain a first measurement result; or, the first message may also instruct the first device 101 to perform positioning reference signal measurement within at least one target time window to obtain a first measurement result and a second measurement result, etc. This disclosure is not limited to this.

[0272] In some embodiments, the measurement result may be a first measurement result; or, it may be a first measurement result and a second measurement result; or, it may be a first measurement result and multiple second measurement results corresponding to at least one target time window, and so on. This disclosure does not limit this.

[0273] Step S2305: The first device 101 sends a third message to the first entity.

[0274] The third message includes the measurement result and / or a time window associated with the measurement result.

[0275] In some embodiments, the first message indicates the relationship between the measurement result and the time window, and the first device 101 may send the measurement result to the first entity 102 only through the third message to reduce signaling overhead.

[0276] In some embodiments, the third message may include any one of the plurality of first measurement results and the second measurement result.

[0277] In some embodiments, the first message does not indicate the relationship between the positioning reference signal measurement result and the time window. In order to ensure that the first entity 102 understands the positioning reference signal measurement result consistently with the first device 101, the first device 101 may also report the time window associated with the measurement result to the first entity 102 when reporting the positioning reference signal measurement result.

[0278] In some embodiments, the third message may include any one of the multiple first measurement results, a time window associated with any one of the first measurement results, and the second measurement result.

[0380] FIG5 is an interactive diagram of a positioning reference signal measurement method according to an embodiment of the present disclosure. As shown in FIG6 , an embodiment of the present disclosure relates to a positioning reference signal measurement method for a positioning system including a first device and a first entity, the method comprising:

[0381] Step S5101: The first entity 102 sends a first message to the first device 101.

[0382] In some embodiments, the first message is used to instruct the first device 101 to measure the positioning reference signal based on multiple positioning reference signal measurement time windows and report the positioning reference signal measurement results, where the measurement results include a first measurement result of carrier phase positioning CPP.

[0383] For a detailed description of step S5101, please refer to the above embodiment description.

[0384] The following is an exemplary introduction to the above method.

[0385] The present disclosure is used to solve the problem of how to trigger an LMF network element to establish user plane positioning based on an association request of a Positioning Reference Unit (PRU). The optional implementation solutions are as follows:

[0386] When the LMF provides multiple time windows to the UE or PRU or gNB through the second message, the multiple time windows are used to instruct the UE or PRU or gNB to measure the positioning reference signal in the time window, or to request the UE or PRU or gNB to measure the positioning reference signal in multiple time windows.

[0387] The LMF uses the first message to instruct the UE, PRU, or gNB on how to measure the positioning reference signal based on the time window to obtain the measurement result. Specifically, it includes:

[0388] Option 1:

[0389] The UE or PRU measures the PRS in each time window, obtains a measurement result for each time window, and then reports the measurement result for each time window to the LMF. For example, if the LMF configures two time windows and requests the UE or PRU to measure the PRS in the time window to obtain the RSCP, the UE measures the PRS in the two time windows, obtains two RSCP values, and reports the two RSCP values ​​to the LMF.

[0390] The gNB measures the SRS in each time window, obtains a measurement result for each time window, and reports the measurement result to the LMF. For example, if the LMF configures two time windows and requests the gNB to measure the SRS in each time window to obtain the RSCP, the gNB measures the PRS in the two time windows, obtains two RSCP values, and reports them to the LMF.

[0391] In some embodiments, each measurement result is associated with a time window, where the associated time window indicates the time window in which the UE, PRU, or gNB measured the positioning reference signal to obtain the measurement result. For example, the associated time window identifier (ID) or index can be used.

[0392] Option 2:

[0393] The UE or PRU measures the PRS in each time window, obtains a measurement result, and reports it to the LMF.

[0394] The gNB measures the SRS in each time window, obtains a measurement result, which is obtained by measuring all time windows and reported to the LMF.

[0395] In some embodiments, the measurement results do not include CPP-related measurement results, such as RSCP and RSCPD.

[0396] Option 3:

[0397] The UE or PRU selects at least one time window to measure the PRS, obtains a measurement result, and reports it to the LMF.

[0398] The gNB selects at least one time window to measure the PRS, obtains a measurement result, and reports it to the LMF.

[0399] The UE, PRU, or gNB indicates a time window associated with the measurement result. The associated time window is used to indicate the time window in which the UE, PRU, or gNB measured the positioning reference signal and obtained the measurement result. For example, the associated time window identifier (ID) or index (index) may be used.

[0400] In some embodiments, the first message may be sent to the UE and PRU via an LPP message (e.g., LPP request location information); and sent to the gNB via an NRPPa message (e.g., NRPPa measurement request message).

[0401] In some embodiments, the UE or PRU reports the measurement results and / or the associated time window via an LPP message (eg, LPP provide location information).

[0402] In some embodiments, the gNB reports the measurement results and / or the associated time window via an NRPPA message (e.g., NRPPa: measurement report).

[0403] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a first device (e.g., a terminal UE, a positioning reference unit PRU, or an access network device) in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a first entity (e.g., an LMF, etc.) in any of the above methods.

[0404] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device.
