[0157] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. 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.

[0158] 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).

[0159] In some embodiments, the first entity 102 may be, for example, a location management function (LMF) network element.

[0160] 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.

[0161] 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.

[0163] 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).

[0164] Release 18 (R18) introduces the Carrier Phase Positioning (CPP) technology. This allows the UE to measure the DL 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 to measure the UL RSCP based on the Uplink (UP) Positioning Reference Signal (SRS).

[0165] 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.

[0166] 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:

[0167] Step S2101 : The first entity 102 sends a first message to the first device 101 .

[0172] In some embodiments, the first message is used to indicate a positioning reference signal measurement time window.

[0173] In some embodiments, when the first device 101 is a UE or a PRU, the first message may be a Long Term Evolution Positioning Protocol (LPP) message.

[0174] In some embodiments, the terms “Long Term Evolution Positioning Protocol LPP”, “Long Term Evolution Positioning Protocol”, “LTE Positioning Protocol”, “LTE Positioning Protocol” and the like may be used interchangeably.

[0175] In some embodiments, when the first device 101 is an access network device, the first message may be a New Radio Positioning Protocol NRPPa message.

[0176] In some embodiments, terms such as "New Radio Positioning Protocol NRPPa", "New Radio Positioning Protocol A", "NR Positioning Protocol A", and "NR Positioning Protocol A" can be used interchangeably.

[0177] In some embodiments, the first device 101 receives a first message sent by the first entity 102 .

[0178] Step S2102 : The first entity 102 determines whether the first device 101 performs a first type of measurement on a positioning reference signal within a time window.

[0179] In some embodiments, the first type of measurement is used to obtain a first measurement result other than a measurement result of carrier phase positioning CPP.

[0180] In some embodiments, the first measurement result is other positioning measurement results except the carrier phase positioning CPP measurement result.

[0181] In some embodiments, the first measurement result may include only one other positioning measurement result, or may include multiple other positioning measurement results, which is not limited in this disclosure.

[0182] In some embodiments, the terms “CPP”, “Carrier Phase Positioning”, and “Carrier Phase Positioning” may be used interchangeably.

[0183] In some embodiments, after receiving the first message, the first device 101 may measure the positioning reference signal within the positioning reference signal measurement time window to obtain CPP-related measurement results, such as RSCPD and RSCP.

[0184] In some embodiments, the terms “RSCPD”, “Reference Signal Carrier Phase Difference”, “Reference Signal Carrier Phase Difference”, etc. may be used interchangeably.

[0185] In some embodiments, the terms “RSCP”, “Reference Signal Carrier Phase”, “reference signal carrier phase”, etc. may be used interchangeably.

[0186] In some embodiments, when the first device 101 is a UE or a PRU, a CPP-related measurement result can be obtained by measuring a PRS within a time window.

[0187] In some embodiments, the terms "PRS", "Positioning Reference Signal", "Positioning Reference Signal" and the like may be used interchangeably.

[0188] In some embodiments, when the first device 101 is an access network device, a CPP-related measurement result can be obtained by measuring the SRS within a time window.

[0189] In some embodiments, the terms "SRS", "Sounding Reference Signal", "Sounding Reference Signal" and the like may be used interchangeably.

[0190] In some embodiments, since the CCP-related measurement results need to be measured within a specified time window, the first measurement result may not be measured within the time window, and the CPP-related measurement results can only be reported together with the first measurement result. Therefore, when the time window is configured, the first entity 102 determines whether the first device 101 performs the first type of measurement on the positioning reference signal within the time window. After that, it can assist the first device in determining whether the first measurement result is obtained within the time window.

[0191] Step S2103 : The first entity 102 sends a second message to the first device 101 .

[0192] In some embodiments, the second message is used to indicate whether the first device 101 performs the first type of measurement on the positioning reference signal within the time window.

[0193] In some embodiments, the second message is used to indicate whether the first device 101 needs to use a positioning reference signal within a time window when obtaining the first measurement result.

[0194] In some embodiments, when the first device 101 is a UE or a PRU, the first device 101 performs positioning reference signal measurement within a time window, and the first measurement result obtained may be UE Rx-Tx time difference, RSTD, PRS-PSRP, PRS-RSRPP, etc., which is not limited in this disclosure.

[0195] In some embodiments, terms such as "Rx-Tx time difference", "transmit-receive time difference", and "Receive-Transmit time difference" can be used interchangeably.

[0197] In some embodiments, the terms "RSRP", "Reference Signal Received Power", "Reference Signal Receiving Power" and the like may be used interchangeably.

[0198] In some embodiments, terms such as “RSRPP”, “reference signal received path power”, and “reference signal receiving path power” may be used interchangeably.

[0199] In some embodiments, the terms "PRS-PSRP", "PRS-reference signal received power", etc. can be used interchangeably.

[0200] In some embodiments, the terms "PRS-RSRPP", "PRS-path reference signal received power", etc. can be used interchangeably.

[0201] 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 first measurement result obtained may be UL-RTOA, UL-AOA, SRS-RSRPP, gNB Rx-Tx time difference, etc., which is not limited in this disclosure.

[0202] In some embodiments, the terms "UL-RTOA", "UpLink Relative Time of Arrival", "UpLink Relative Time of Arrival" and the like may be used interchangeably.

[0203] In some embodiments, the terms "UL-AOA", "UL Angle of Arrival", "UpLink Angle of Arrival" and the like may be used interchangeably.

[0204] In some embodiments, the terms "SRS-RSRPP", "SRS-path reference signal received power", etc. can be used interchangeably.

[0205] In some embodiments, when the first device 101 is a UE or a PRU, the second message may be a Long Term Evolution Positioning Protocol (LPP) message.

[0206] In some embodiments, when the first device is an access network device, the second message may be a New Radio Positioning Protocol NRPPa message.

[0207] In some embodiments, the first device 101 receives the second message sent by the first entity 102 .

[0208] Step S2104: The first device 101 determines whether to perform a first type of measurement on the positioning reference signal within the time window based on the second message.

[0209] In some embodiments, after receiving the second message, first device 101 may determine whether to perform the first type of measurement on the positioning reference signal within the time window. For example, first device 102 may determine, based on the second message, whether to measure the PRS (or SRS) within the time window to obtain the Rx-Tx time difference.

[0210] In some embodiments, when the first device 101 is a UE or a PRU, the first device 101 can determine whether to measure the PRS within the time window based on the second message to obtain a first measurement result, such as obtaining at least one of UE Rx-Tx time difference, RSTD, PRS-RSRP, PRS-RSRPP, etc., which is not limited in this disclosure.

[0211] In some embodiments, when the first device 101 is an access network device, the first device 101 can determine whether to measure the SRS within the time window based on the second message to obtain a first measurement result, such as obtaining at least one of UL-RTOA, UL-AOA, SRS-RSRPP, gNB Rx-TX time difference, etc., which is not limited in this disclosure.

[0212] In step S2105 , the first device 101 measures the positioning reference signal and obtains all measurement results requested by the first entity 102 .

[0213] In some embodiments, after determining whether to perform the first type of measurement on the positioning reference signal within the time window, the first device 101 may measure the positioning reference signal to obtain all measurement results requested by the first entity.

[0214] For example, the first entity 102 requests the first device 101 to report RSCPD and Rx-Tx time difference, and the second message instructs the first device to measure the positioning reference signal within the time window to obtain a first measurement result. Then the first device 101 can measure the positioning reference signal (SRS or PRS) within the time window to obtain RSCPD and Rx-Tx time difference.

[0215] In some embodiments, the first entity 102 requests the first device 101 to report RSCPD and Rx-Tx time difference, and the second message indicates that the first device does not measure the positioning reference signal within the time window to obtain the first measurement result. Then, the first device 101 can measure the SRS or PRS within the time window to obtain RSCPD, and measure the SRS or PRS in other time periods to obtain the Rx-Tx time difference.

[0216] In some embodiments, when the first device 101 is a UE or a PRU, all measurement results requested by the first entity 102 can be obtained by measuring the PRS within a configured time window.

[0217] In some embodiments, when the first device is an access network device, all measurement results requested by the first entity 102 may be obtained by measuring the SRS within a configured time window.

[0218] Step S2106 : The first device 101 sends a fourth message to the first entity 102 .

[0219] In some embodiments, the fourth message includes the measurement result.

[0220] In some embodiments, when the first device 101 is a UE or a PRU, the fourth message may be a Long Term Evolution Positioning Protocol (LPP) message.

[0221] In some embodiments, when the first device is an access network device, the fourth message may be a New Radio Positioning Protocol NRPPa message.

[0222] In some embodiments, after obtaining all measurement results requested by the first entity 102 , the first device 101 may report the measurement results to the first entity 102 .

[0223] In some embodiments, the measurement result reported by the first device 101 is the first measurement result and the CPP-related measurement result.

[0224] In some embodiments, the first entity 102 receives the fourth message sent by the first device 101 .

[0225] The positioning reference signal measurement method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2106. For example, step S2101 may be implemented as an independent embodiment, step S2102 may be implemented as an independent embodiment, and steps S2101+S2103 may be implemented as independent embodiments, but are not limited thereto.

[0226] 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.

[0227] In this embodiment, the first entity indicates to the first device a positioning reference signal measurement time window and whether to perform positioning reference signal measurements within the time window to obtain a first measurement result. The first device can then measure and report the positioning reference signal based on the first entity's instructions. This ensures that the first device and the first entity have a consistent understanding of how to use the time window, and thus, a consistent understanding of the positioning measurement results, thereby improving the reliability and accuracy of positioning in the communication system.

[0228] FIG2B is an interactive diagram of a positioning reference signal measurement method according to an embodiment of the present disclosure. As shown in FIG2B , an embodiment of the present disclosure relates to a positioning reference signal measurement method, the method comprising:

[0229] Step S2201: The first entity 102 sends a first message to the first device 101.

[0230] For a detailed introduction to step S2201, please refer to the above step S2101.

[0231] Step S2202: The first device 101 determines whether to perform a first type of measurement on a positioning reference signal within a time window.

[0232] In some embodiments, the first type of measurement is used to obtain a first measurement result other than a measurement result of carrier phase positioning CPP.

[0233] In some embodiments, the first measurement result is other positioning measurement results except for the measurement result of the carrier phase positioning CPP.

[0234] The specific implementation of the first type of measurement refers to the description of the optional implementation of step S2102, which will not be repeated here.

[0235] 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 the time window, then the first device 101 can determine whether to perform the first type of measurement on the positioning reference signal within the time window according to the protocol agreement.

[0236] In some embodiments, the first device 101 may also determine whether to perform the first type of measurement on the positioning reference signal within the time window according to configuration information of the first device 101 itself.

[0237] In step S2203 , the first device 101 performs positioning reference signal measurement to obtain all measurement results.

[0238] In some embodiments, if the first device determines to perform positioning reference signal measurement within the time window to obtain a first measurement result, then the first device may perform positioning reference signal measurement within the time window to obtain all measurement results requested by the first entity.

[0239] In some embodiments, the first entity 102 requests the first device 101 to report RSCPD and RSRP, and the first device determines to measure the positioning reference signal within the time window based on the protocol agreement (or configuration information) to obtain a first measurement result. Then, the first device 101 can measure the SRS or PRS within the time window to obtain RSCPD and RSRP.

[0240] In some embodiments, the first entity 102 requests the first device 101 to report RSCPD and RSRP, and the first device determines not to measure the positioning reference signal within the time window based on the protocol agreement (or configuration information) to obtain a first measurement result. Then, the first device 101 can measure the SRS or PRS within the time window to obtain RSCPD, and measure the SRS or PRS in other time periods to obtain RSRP.

[0241] Step S2204 : The first device 101 sends a fourth message to the first entity 102 .

[0242] In some embodiments, the fourth message includes the measurement result and an associated time window of the measurement result.

[0243] In some embodiments, to ensure that the first entity 102 understands the measurement result in a consistent manner with the first device 101 , the first device may also report the associated time window of the measurement result to the first entity 102 when reporting the measurement result.

[0244] In some embodiments, the first message indicates the positioning reference signal measurement time window #1, the first entity 102 requests the first device to report RSCPD and RSRP, and the first device 101 determines that the RSCPD and RSRP are obtained by measuring the positioning reference signal in time window #1. Then, after the first device 101 obtains the RSCPD and RSRP by measuring, it can report the RSCPD and RSRP through the fourth message and report the time window #1 at the same time to indicate to the first entity 102 that the RSCPD and RSRP are obtained by measuring the positioning reference signal in time window #1.

[0245] In some embodiments, the first message indicates positioning reference signal measurement time window #1 and time window #2. First entity 102 requests the first device to report RSCPD and RSRP. First device 101 determines that RSCPD is obtained by measuring the positioning reference signal in time window #1 and RSRP is obtained by measuring the positioning reference signal in time window #2. After obtaining the RSCPD and RSRP through measurement, first device 101 may report the RSCPD and RSRP through a fourth message, with the RSCPD associated with time window #1 and the RSRP associated with time window #2. This indicates to first entity 102 that the RSCPD was obtained by measuring the positioning reference signal in time window #1 and the RSRP was obtained by measuring the positioning reference signal in time window #2.

[0246] The positioning reference signal measurement method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2204. For example, step S2201 may be implemented as an independent embodiment, step S2202 may be implemented as an independent embodiment, and steps S2201+S2203 may be implemented as independent embodiments, but are not limited thereto.

[0247] 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.

[0248] In this embodiment, after the first entity indicates a positioning reference signal measurement time window to the first device, the first device determines whether to perform the first type of measurement on the positioning reference signal within the time window based on protocol provisions or its own configuration information, and then measures and reports the positioning reference signal. This improves the efficiency of positioning in the communication system.

[0249] FIG2C is an interactive diagram illustrating a method for measuring a positioning reference signal according to an embodiment of the present disclosure. As shown in FIG2C , an embodiment of the present disclosure relates to a method for measuring a positioning reference signal, the method comprising:

[0250] Step S2301: The first entity 102 sends a first message to the first device 101.

[0251] For a detailed introduction to step S2201, please refer to the above step S2101.

[0252] Step S2302: In the case of multiple time windows, the first entity 102 determines the association relationship between the time windows and the measurement results.

[0253] Among them, the association relationship between the time window and the measurement result can also be called the associated measurement result of the time window, or the associated time window of the measurement result, or the measurement result associated with the time window, or the time window associated with the measurement result, etc., which is not limited in this disclosure.

[0254] In some embodiments, the measurement results include a first measurement result and / or a measurement result of the CPP.

[0255] In some embodiments, the first entity 102 may associate at least one time window with each measurement result. For example, the first entity 102 configures time window #1, time window #2, and time window #3 for the first device 101. The first entity 102 requests measurement results such as RSTD, Rx-Tx time difference, and RSCP. The first entity 102 may associate RSTD with time window #1, Rx-Tx time difference with time window #2, and RSCP with time window #3.

[0256] Step S2303 : The first entity 102 sends a third message to the first device 101 .

[0257] In some embodiments, the third message is used to indicate an association between the time window and the measurement result.

[0258] In some embodiments, the third message may be a measurement result reporting request message, which may include all measurement results requested to be reported by the first device 101 and the associated time window of each measurement result.

[0259] For example, the first entity 102 configures time window #1 and time window #2 for the first device 101 through a first message. In addition, the first entity 102 requests the first device 101 to report RSCP, RSTD and RSRP through a third message, and the third message indicates that the associated time windows of RSCP and RSTD are both time window #1, and the associated time window of RSRP is time window #2.

[0260] In some embodiments, the third message and the first message may be the same message, that is, the third message is a time window configuration message, which may include associated measurement results of each time window, etc., which is not limited in this disclosure.

[0261] For example, the first entity 102 configures time window #1 and time window #2 for the first device 101 through the first message (third message), and indicates in the first message that the associated measurement result of time window #1 is RSCP and the associated measurement result of time window #2 is RSRP.

[0262] It should be noted that, in the embodiment of the present disclosure, a time window may be associated with a CPP and one other positioning measurement result; or, a time window may be associated with a CPP and all other positioning measurement results; or, a time window may be associated with only one CPP, or, only one other positioning measurement result, etc., and the present disclosure does not limit this.

[0263] In the embodiment of the present disclosure, step S2301 may be executed simultaneously with step S2302 and step S2303, and the present disclosure does not limit this.

[0264] In some embodiments, when the first device 101 is a UE or a PRU, the third message may be a Long Term Evolution Positioning Protocol (LPP) message.

[0265] In some embodiments, when the first device 101 is an access network device, the third message may be a New Radio Positioning Protocol NRPPa message.

[0266] In some embodiments, the first device 101 receives a third message sent by the first entity 102 .

[0267] In step S2304 , the first device 101 performs positioning reference signal measurement within the time window to obtain associated measurement results.

[0268] In some embodiments, if the third message indicates the association relationship between the time window and the measurement result, the first device 101 can determine the association relationship between the time window and the measurement result based on the third message, and perform positioning reference signal measurement within the time window to obtain the associated measurement result.

[0269] In some embodiments, if the third message does not indicate a time window associated with the first measurement result, the first device 101 does not perform positioning reference signal measurements to obtain the first measurement result within the time window. For example, if the first entity 102 does not configure a time window for RSTD, the first device 101 may not need to perform measurements to obtain RSTD within the time window.

[0270] In some embodiments, if the third message does not indicate the association between the time window and the measurement result, but requests the first device 101 to report the measurement result, then the first device 101 can determine the association between the time window and the measurement result based on the protocol agreement or the configuration information of the first device 101 itself.

[0271] Step S2305 : The first device 101 sends a fourth message to the first entity 102 .

[0272] For a detailed introduction to step S2305, please refer to the above-mentioned step S2105 and / or step S2205.

[0273] The positioning reference signal measurement method involved in the embodiments of the present disclosure may include at least one of steps S2301 to S2305. For example, step S2301 may be implemented as an independent embodiment, step S2302 may be implemented as an independent embodiment, and steps S2301+S2303 may be implemented as independent embodiments, but are not limited thereto.

[0274] 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.

[0275] In this embodiment, the first entity indicates a positioning reference signal measurement time window to the first device. In the case of multiple time windows, after determining the association between the time window and the measurement result, the first entity indicates the association between the time window and the measurement result to the first device. The first device then measures and reports the positioning reference signal within the time window. Thus, by indicating the association between the time window and the measurement result to the first device based on the first entity, a consistent understanding of the positioning measurement results between the first entity and the first device is ensured, thereby improving the accuracy of positioning in the communication system.

[0276] FIG3A is a flow chart of a method for measuring a positioning reference signal according to an embodiment of the present disclosure. As shown in FIG3A , the embodiment of the present disclosure relates to a method for measuring a positioning reference signal, which is used by a first device 101 and includes:

[0423] Step S5101: The first entity 102 sends a first message to the first device 101.

[0424] In some embodiments, the first message is used to indicate a positioning reference signal measurement time window.

[0425] Step S5102: The first device 101 determines whether to perform a first type of measurement on a positioning reference signal within a time window.

[0426] For a detailed description of steps S5101 - S5102 , please refer to the above embodiment description.

[0427] 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 the first type of measurement on the positioning reference signal within the time window, thereby improving the efficiency of positioning in the communication system.

[0428] The following is an exemplary introduction to the above method.

[0429] This disclosure is used to solve the problem of how to constrain traditional measurement behavior after configuring a time window. The optional implementation solutions are as follows:

[0430] The present disclosure relates to a method for measuring a positioning reference signal. Taking a first device as a terminal UE, a PRU, or a gNB as an example, the method includes:

[0431] If a time window is configured, the time window can be applied to CPP and other legacy measurements (eg, Rx-Tx time difference, RSRP, RSRPP).

[0432] If a time window is configured, the time window may apply to CPP and the LMF may indicate whether it is used for legacy measurements (additional indication). If there is no additional indication from the LMF, the time window is only used for CPP-related measurement results, or it is up to the UE or gNB to decide whether the time window is used for legacy measurements.

[0433] If a time window is configured, the LMF can indicate which measurement type the time window applies to, including CPP and legacy measurements. If the LMF does not indicate, it is up to the UE or gNB to decide whether to use the time window.

[0434] 1. When the LMF configures a time window for the UE, PRU, or gNB, the time window is used to instruct the UE, PRU, or gNB to measure the positioning reference signal in the time window.

[0435] 2. The UE or PRU (equivalent to the measurement behavior of the UE or PRU specified in the protocol) measures the PRS within a given time window and obtains all measurement results requested by the LMF. For example, if the LMF requests the UE to report RSCPD and Rx-Tx time difference, the UE can measure the PRS within the time window and obtain RSCPD and Rx-Tx time difference.

[0436] 3. The gNB measures the SRS in a given time window and obtains all measurement results requested by the LMF. For example, if the LMF requests the gNB to report RSCPD and Rx-Tx time difference, the gNB can measure the SRS within the time window and obtain RSCPD and Rx-Tx time difference.

[0437] 4. The UE or PRU measures the PRS in a given time window and obtains CPP-related measurement results, such as RSCPD and RSCP. It can also determine whether to measure the PRS in the time window based on the LMF's instructions to obtain measurement results other than CPP. For example, the LMF instructs the UE or PRU whether to measure the PRS in the time window to obtain the Rx-Tx time difference.

[0438] 5. Based on 4, if there is no indication, the UE or PRU determines whether to measure the PRS in the time window based on implementation, and obtains measurement results other than CPP.

[0439] 6. The gNB measures the SRS in a given time window and obtains CPP-related measurement results, such as RSCPD and RSCP. It can also determine whether to measure the SRS in the time window based on the LMF's instructions to obtain measurement results other than CPP. For example, the LMF instructs the gNB whether to measure the PRS in the time window to obtain the Rx-Tx time difference.

[0440] 7. Based on 6, if there is no indication, the gNB determines based on implementation whether to measure SRS in the time window and obtain measurement results outside of CPP.

[0441] 8. The LMF may indicate to the UE / PRU / gNB the measurement results to which the time window applies, including CPP-related measurements and positioning measurements outside of CPP. If the LMF does not indicate this, the UE / PRU / gNB may determine, based on implementation, which measurement results to apply to the time window.

[0442] 9. The LMF may request the UE / PRU / gNB to report measurement results and configure a time window for each measurement result. That is, each measurement result may be associated with one 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 measurement result, the UE / PRU / gNB does not need to perform measurements in the time window configured for other measurement results.

[0443] 10. The indication may be sent via an LPP message (LPP location information request) or an NRPPa message (measurement request).

[0444] 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 terminal 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., a RAN) in any of the above methods.

[0445] 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. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits, and the functions of some or all of the units or modules can be realized by designing the hardware circuits. The above-mentioned hardware circuits can be understood as one or more processors; for example, in one implementation, the above-mentioned hardware circuit is an application-specific integrated circuit (ASIC), which realizes the functions of some or all of the above units or modules by designing the logical relationship of the components in the circuit; for example, in another implementation, the above-mentioned hardware circuit can be realized by a programmable logic device (PLD). Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

[0446] In the embodiments of the present disclosure, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of the hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA.
