[0260] FIG2A is an interactive diagram of a positioning measurement processing method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a positioning measurement processing method, the method comprising:

[0261] Step S2101: The access network device sends a first positioning reference signal to the terminal.

[0262] In some embodiments, the access network device may send the first positioning reference signal to the terminal on multiple first frequency layers used to send the first positioning reference signal.

[0263] The multiple first frequency layers used to send the first positioning reference signal are used for bandwidth aggregation of the first positioning reference signal. That is, the terminal may be a terminal configured with bandwidth aggregation.

[0264] In some embodiments, the terminal may monitor the first positioning reference signal in multiple first frequency layers to obtain a positioning measurement result of the terminal by measuring the first positioning reference signal.

[0265] The first positioning reference signal may be a positioning reference signal (PRS). Optionally, the first positioning reference signal may be sent by an access network device to the terminal. For example, the access network device may send the PRS to the terminal on multiple first frequency layers.

[0266] Step S2102: The terminal determines at least one second frequency layer among multiple first frequency layers used to send the first positioning reference signal.

[0267] It should be noted that the terminal may have the ability to receive the first positioning reference signal on multiple first frequency layers, but when obtaining different types of positioning measurement results, the first frequency layers of the first positioning reference signal used for measurement may be different.

[0268] In some embodiments, the terminal may determine at least one second frequency layer from among the multiple first frequency layers. Optionally, the terminal may have the capability to actively select the second frequency layer, or the terminal may determine the second frequency layer according to an instruction from a core network device.

[0269] In some embodiments, the terminal has the ability to actively select the second frequency layer. For example, the terminal may determine at least one second frequency layer from multiple first frequency layers according to the type of positioning measurement results to be obtained.

[0270] In some embodiments, the positioning measurement result is a positioning measurement result related to carrier phase positioning (CPP), and the terminal may select one first frequency layer from multiple first frequency layers as the second frequency layer.

[0271] The CPP-related positioning measurement result represents a measurement result obtained by the terminal measuring the carrier phase of a reference signal. Optionally, the CPP-related positioning measurement result may include, but is not limited to, a reference signal carrier phase (RSCP) and / or a reference signal carrier phase difference (RSCPD). The CPP-related positioning measurement result may also include other types of positioning measurement results, which are not limited in the embodiments of the present disclosure.

[0272] For example, the terminal may select a second frequency layer from multiple first frequency layers to measure a first positioning reference signal (such as a PRS) to obtain RSCP and / or RSCPD.

[0273] Optionally, the terminal may select a first frequency layer from multiple first frequency layers as the second frequency layer based on the first default condition, where the second frequency layer may be used to measure a CPP-related positioning measurement result.

[0274] For example, the terminal may determine a default frequency layer (default frequency layer) from multiple first frequency layers based on the first default condition, so that the default frequency layer may be used as the second frequency layer for measuring the CPP-related positioning measurement result.

[0275] Optionally, the first default condition may include any one of the following:

[0276] The second frequency level corresponds to the first frequency value in the frequency list;

[0277] The second frequency layer is the frequency layer with the lowest frequency point among the multiple first frequency layers;

[0278] The second frequency layer is the frequency layer with the largest bandwidth among the multiple first frequency layers.

[0279] That is, the default frequency layer may be the frequency layer corresponding to the first frequency in the frequency list; or, the default frequency layer may be the frequency layer with the lowest frequency among multiple first frequency layers; or, the default frequency layer may be the frequency layer with the largest bandwidth among multiple first frequency layers.

[0280] In some embodiments, the positioning measurement result is a CPP-related positioning measurement result, and the terminal can also determine each first frequency layer in multiple first frequency layers as a second frequency layer, so that the first positioning reference signal can be measured separately on each second frequency layer subsequently.

[0281] The introduction of the positioning measurement results related to CPP can be found in the above embodiment and will not be repeated here.

[0282] In some embodiments, the positioning measurement result is a non-time-related positioning measurement result, and the terminal may select at least one first frequency layer from multiple first frequency layers as the second frequency layer.

[0283] The time-related positioning measurement results may include at least one of reference signal time difference (RSTD), user equipment receive-transport time difference (UE Rx-Tx time difference), and time of arrival (TOA), but are not limited thereto. The time-related positioning measurement results may also include other types of positioning measurement results. It should be noted that other positioning measurement results other than the positioning measurement results listed above are non-time-related positioning measurement results.

[0284] In some embodiments, the positioning measurement result is a non-CPP-related positioning measurement result, and the terminal can select at least one first frequency layer from multiple first frequency layers as the second frequency layer, or the terminal can determine the second frequency layer based on the bandwidth aggregation configuration of the first positioning reference signal.

[0285] Optionally, the terminal may determine, according to a protocol agreement, how to determine the second frequency layer for obtaining non-CPP related positioning measurement results, or the terminal may freely select, based on implementation, how to determine the second frequency layer for obtaining non-CPP related positioning measurement results.

[0286] The non-CPP-related positioning measurement results may include at least reference signal received power (RSRP) and / or reference signal received path power (RSRPP). Optionally, the non-CPP-related positioning measurement results may further include time-related positioning measurement results, for example, the non-CPP-related positioning measurement results may further include angle of arrival (AOA).

[0287] For example, the terminal may select at least one first frequency layer from a plurality of first frequency layers to measure a first positioning reference signal (such as a PRS) to obtain an RSCP and / or an RSRPP.

[0288] For another example, the terminal may measure the first positioning reference signal (such as PRS) according to the bandwidth aggregation configuration of the first positioning reference signal to obtain RSRP and / or RSRPP.

[0289] Through the above embodiment, the terminal can independently determine the second frequency layer for measuring the first positioning reference signal from multiple first frequency layers. In more possible implementations, the terminal can also determine the second frequency layer according to the instruction of the core network device.

[0290] In some embodiments, the core network device can send first indication information to the terminal, and the first indication information can be used to indicate the second frequency layer; the terminal can receive the first indication information sent by the core network device, and thereby select at least one second frequency layer from multiple first frequency layers based on the first indication information.

[0291] In some embodiments, the core network device may send a first positioning request message to the terminal, and the first positioning request message may include first indication information; the terminal may receive the first positioning request message sent by the core network device to obtain the first indication information included in the first positioning request message.

[0292] Optionally, the core network device may send the first positioning request message to the access network device, and the access network device transparently transmits the first positioning request message to the terminal, so that the terminal can receive the first positioning request message sent by the core network device.

[0293] Among them, the first positioning request message can be an LTE Positioning Protocol (LPP) message based on LTE. For example, the first positioning request message can be a message in the LPP message used to request location information (that is, LPP request location information), but is not limited to this. The first positioning request message can also be other types of messages, which is not limited in the embodiments of the present disclosure.

[0294] In some embodiments, the first indication information may indicate the first frequency layer by any one of the following: a frequency point number; a reference frequency point; a common reference point (Point A); a frequency layer index (frequency layer index); a first positioning reference signal resource set identifier (PRS resource set ID); a first positioning reference signal resource identifier; a frequency layer identifier (frequency layer ID).

[0295] Among them, the reference frequency point can be the NR absolute radio frequency channel number (NR absolute radio frequency channel number, NR-ARFCN), but is not limited to this. The reference frequency point can also be other types, which is not limited in the embodiments of the present disclosure.

[0296] Optionally, the first indication information may also indicate the second frequency layer in other ways, which is not limited in the embodiment of the present disclosure.

[0297] In some embodiments, the positioning measurement result is a CPP-related positioning measurement result, and the terminal may select one first frequency layer from multiple first frequency layers as the second frequency layer based on the first indication information.

[0298] The introduction of the positioning measurement results related to CPP can be found in the above embodiment and will not be repeated here.

[0299] For example, the terminal may select a second frequency layer for measuring RSCP and / or RSCPD from multiple first frequency layers according to an instruction of the core network device.

[0300] In some embodiments, the positioning measurement result is a non-time-related and / or non-CPP-related positioning measurement result, and the terminal may select at least one first frequency layer from multiple first frequency layers as the second frequency layer based on the first indication information.

[0301] The introduction of the non-time-related positioning measurement results and the non-CPP-related positioning measurement results can be found in the above embodiments, which will not be repeated here.

[0302] For example, the terminal may select at least one second frequency layer for measuring RSRP and / or RSRPP from multiple first frequency layers according to an instruction of the core network device.

[0303] Step S2103: The terminal measures the first positioning reference signal on the second frequency layer to obtain a positioning measurement result.

[0304] In some embodiments, after determining the second frequency layer from the plurality of first frequency layers, the terminal may measure the first positioning reference signal on the second frequency layer to obtain a positioning measurement result.

[0305] In some embodiments, the terminal may measure the first positioning reference signal on a second frequency layer determined from the plurality of first frequency layers to obtain a CPP-related positioning measurement result.

[0306] For example, the terminal may measure the PRS on a second frequency layer determined from the multiple first frequency layers to obtain the RSCP and / or RSCPD.

[0307] In some embodiments, the terminal may use each first frequency layer of the multiple first frequency layers as a second frequency layer, and the terminal may measure the first positioning reference signal on each second frequency layer to obtain a CPP-related positioning measurement result.

[0308] For example, the network configures three first frequency layers for the terminal. The terminal can select each of the three first frequency layers as the second frequency layer, that is, three second frequency layers are determined. The terminal can measure the PRS on each second frequency layer to obtain RSCP and / or RSCPD, that is, the terminal can obtain three positioning measurement results (that is, RSCP and / or RSCPD), where each second frequency layer corresponds to one positioning measurement result.

[0309] In some embodiments, the terminal may measure the first positioning reference signal on at least one second frequency layer determined from the plurality of first frequency layers to obtain a non-time-related and / or non-CPP-related positioning measurement result.

[0310] For example, the terminal may measure the PRS on at least one second frequency layer determined from the multiple first frequency layers to obtain RSRP and / or RSRPP.

[0311] In some embodiments, the terminal may measure the first positioning reference signal according to the bandwidth aggregation configuration of the first positioning reference signal to obtain a non-CPP related positioning measurement result.

[0312] For example, the terminal may measure the PRS according to the bandwidth aggregation configuration of the PRS to obtain RSRP and / or RSRPP.

[0313] Step S2104: The terminal sends the positioning measurement result to the core network device through the access network device.

[0314] In some embodiments, the terminal may send the positioning measurement result to the access network device, and the access network device may transparently transmit the positioning measurement result to the core network device, so that the core network device may receive the positioning measurement result sent by the terminal.

[0315] It should be noted that, when the terminal determines the second frequency layer according to the instructions of the core network device, the second frequency layer determined by the terminal itself is indicated by the core network device. Therefore, the core network device already knows the frequency layer of the terminal measuring the first positioning reference signal. Therefore, the terminal can directly send the positioning measurement results to the core network device.

[0316] In the case where the terminal selects the second frequency layer by itself, the terminal can send second indication information to the core network device, where the second indication information is used to indicate the second frequency layer so that the core network device can locate the terminal according to the second frequency layer indicated by the second indication information.

[0317] In some embodiments, the terminal may send a first positioning response message to the core network device, and the first positioning response message may include second indication information to implement the sending of the second indication information.

[0318] Optionally, the terminal may send the first positioning response message to the access network device, and the access network device may transparently transmit the first positioning response message to the core network device, so that the core network device may receive the first positioning response message sent by the terminal.

[0319] Among them, the first positioning response message can be an LPP message. For example, the first positioning response message can be a message in the LPP message used to provide location information (that is, LPP provide location information), but is not limited to this. The first positioning response message can also be other types of messages, and the embodiments of the present disclosure are not limited to this.

[0320] In some embodiments, the second indication information can indicate the first frequency layer through any one of the following items: frequency point number; reference frequency point; common reference point; frequency layer index; first positioning reference signal resource set identifier; first positioning reference signal resource identifier; frequency layer identifier; bandwidth aggregation identifier.

[0321] The reference frequency point may be NR-ARFCN, but is not limited thereto. The reference frequency point may also be other types, which is not limited in the embodiments of the present disclosure.

[0322] Optionally, the second indication information may also indicate the second frequency layer in other ways, which is not limited in the embodiment of the present disclosure.

[0323] Step S2105: The core network device obtains the positioning measurement result.

[0324] In some embodiments, the core network device may receive the positioning measurement result sent by the terminal to obtain the positioning measurement result obtained by the terminal on the second frequency layer.

[0325] It should be noted that, in the case where the terminal determines the second frequency layer according to the instructions of the core network device, the second frequency layer determined by the terminal itself is indicated by the core network device. Therefore, the core network device already knows the frequency layer on which the terminal measures the first positioning reference signal. Therefore, in this case, the core network device only needs to receive the positioning measurement results obtained by the terminal on the second frequency layer.

[0326] In the case where the terminal selects the second frequency layer by itself, the terminal will also send second indication information to the core network device to indicate the second frequency layer. Therefore, in some embodiments, the core network device can also receive the second indication information sent by the terminal to determine the frequency layer used by the terminal to measure the first positioning reference signal based on the second frequency layer indicated by the second indication information.

[0327] In some embodiments, the core network device may receive a first positioning response message sent by the terminal. The first positioning response message may include second indication information, so that the core network device can obtain the second indication information. For an introduction to the first positioning response message and the second indication information, refer to the above embodiment and are not repeated here.

[0328] It should be noted that the frequency layer involved in the embodiments of the present disclosure may also be a bandwidth part (Bandwidth Part, BWP) or a carrier (carrier), but is not limited thereto, and the embodiments of the present disclosure are not limited thereto.

[0329] It should be noted that, in the embodiment of the present disclosure, the first network element of the core network device may interact with the terminal.

[0330] The positioning measurement processing method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2105. For example, step S2102 may be implemented as an independent embodiment, step S2104 may be implemented as an independent embodiment, step S2101 and step S2102 may be implemented as independent embodiments, step S2102 and step S2103 may be implemented as independent embodiments, and step S2103 and step S2104 may be implemented as independent embodiments, but the present invention is not limited thereto.

[0331] In some embodiments, step S2101, step S2102, and step S2103 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0332] In some embodiments, step S2104 is optional and may be omitted or replaced in different embodiments.

[0333] FIG2B is an interactive diagram of a positioning measurement processing method according to an embodiment of the present disclosure. As shown in FIG2B , the embodiment of the present disclosure relates to a positioning measurement processing method, which includes:

[0334] Step S2201: The access network device receives a second positioning reference signal sent by a terminal.

[0335] In some embodiments, the terminal may send the second positioning reference signal to the access network device on multiple third frequency layers used to send the second positioning reference signal.

[0336] The multiple third frequency layers used to send the second positioning reference signal are used for bandwidth aggregation of the second positioning reference signal. That is, the access network device may be a device configured with bandwidth aggregation.

[0337] In some embodiments, the access network device may monitor the second positioning reference signal in multiple third frequency layers to obtain a positioning measurement result of the terminal by measuring the second positioning reference signal.

[0338] The second positioning reference signal may be a sounding reference signal (SRS). Optionally, the second positioning reference signal may be sent by the terminal to the access network device. For example, the terminal may send the SRS to the access network device on multiple third frequency layers.

[0339] Step S2202: The access network device determines at least one fourth frequency layer among multiple third frequency layers used to send the second positioning reference signal.

[0340] It should be noted that the access network device may have the ability to receive the second positioning reference signal on multiple third frequency layers, but when obtaining different types of positioning measurement results, the fourth frequency layer of the second positioning reference signal used for measurement may be different.

[0341] In some embodiments, the access network device may determine at least one fourth frequency layer from multiple third frequency layers. Optionally, the access network device may have the ability to actively select the fourth frequency layer, or the access network device may determine the fourth frequency layer based on an instruction from a core network device.

[0342] In some embodiments, the access network device has the ability to actively select the fourth frequency layer. For example, the access network device can determine at least one fourth frequency layer from multiple third frequency layers according to the type of positioning measurement results to be obtained.

[0343] In some embodiments, the positioning measurement result is a CPP-related positioning measurement result, and the terminal may select a third frequency layer from multiple third frequency layers as the fourth frequency layer.

[0344] The CPP-related positioning measurement result represents a measurement result obtained by the terminal measuring the carrier phase of a reference signal. Optionally, the CPP-related positioning measurement result may include, but is not limited to, RSCP and / or RSCPD. The CPP-related positioning measurement result may also include other types of positioning measurement results, which are not limited in the embodiments of the present disclosure.

[0345] For example, the access network device may select a fourth frequency layer from multiple third frequency layers to measure the second positioning reference signal (such as SRS) to obtain RSCP and / or RSCPD.

[0346] Optionally, the access network device may select a third frequency layer from multiple third frequency layers as a fourth frequency layer based on the second default condition, wherein the fourth frequency layer may be used to measure a CPP-related positioning measurement result.

[0347] For example, the access network device may determine a default frequency layer from multiple third frequency layers based on the second default condition, so that the default frequency layer may be used as the fourth frequency layer for measuring the CPP-related positioning measurement result.

[0348] Optionally, the second default condition may include any one of the following:

[0349] The fourth frequency level corresponds to the first frequency value in the frequency list;

[0350] The fourth frequency layer is the frequency layer with the lowest frequency point among the multiple third frequency layers;

[0351] The fourth frequency layer is a frequency layer with the largest bandwidth among the plurality of third frequency layers.

[0352] That is, the default frequency layer may be the frequency layer corresponding to the first frequency in the frequency list; or, the default frequency layer may be the frequency layer with the lowest frequency point among multiple third frequency layers; or, the default frequency layer may be the frequency layer with the largest bandwidth among multiple third frequency layers.

[0353] In some embodiments, the positioning measurement result is a CPP-related positioning measurement result, and the terminal can also determine each of the multiple third frequency layers as the fourth frequency layer, so that the second positioning reference signal can be measured on each fourth frequency layer separately.

[0354] The introduction of the positioning measurement results related to CPP can be found in the above embodiment and will not be repeated here.

[0355] In some embodiments, the positioning measurement result is a non-time-related positioning measurement result, and the access network device may select at least one frequency layer from multiple third frequency layers as the fourth frequency layer.

[0356] The time-related positioning measurement results may include at least one of uplink relative time of arrival (UL RTOA), RSTD, gNB receive-transmit time difference (gNB Rx-Tx time difference), and TOA, but are not limited thereto. The time-related positioning measurement results may also include other types of positioning measurement results. It should be noted that positioning measurement results other than the aforementioned positioning measurement results are non-time-related positioning measurement results.

[0357] For example, the access network device may select at least one fourth frequency layer from multiple third frequency layers to measure the second positioning reference signal (such as SRS) to obtain RSCP and / or RSRPP.

[0358] In some embodiments, the positioning measurement result is a non-CPP-related positioning measurement result, and the access network device can select at least one frequency layer from multiple third frequency layers as the fourth frequency layer, or the access network device can determine the fourth frequency layer based on the bandwidth aggregation configuration of the second positioning reference signal.

[0359] Optionally, the terminal may determine, according to a protocol agreement, how to determine the fourth frequency layer for obtaining non-CPP related positioning measurement results, or the terminal may freely choose, based on implementation, how to determine the fourth frequency layer for obtaining non-CPP related positioning measurement results.

[0360] The non-CPP related positioning measurement results may include at least RSRP and / or RSRPP. Optionally, the non-CPP related positioning measurement results may further include time-related positioning measurement results, for example, the non-CPP related positioning measurement results may further include AOA.

[0361] For example, the access network device may measure the second positioning reference signal (such as SRS) according to the bandwidth aggregation configuration of the second positioning reference signal to obtain at least one of RSRP, RSRPP, and UL AOA.

[0362] Through the above embodiments, the access network device can independently determine the fourth frequency layer for measuring the second positioning reference signal from multiple third frequency layers. In more possible implementations, the access network device can also determine the fourth frequency layer according to the instructions of the core network device.

[0363] In some embodiments, the core network device can send third indication information to the access network device, and the third indication information can be used to indicate the third frequency layer; the access network device can receive the third indication information sent by the core network device, and thereby select at least one fourth frequency layer from multiple third frequency layers based on the third indication information.

[0364] In some embodiments, the core network device may send a second positioning request message to the access network device, and the second positioning request message may include third indication information; the access network device may receive the second positioning request message sent by the core network device to obtain the third indication information included in the second positioning request message.

[0365] Among them, the second positioning request message can be a New Radio Positioning Protocol A (NRPPa) message. For example, the second positioning request message can be a measurement request message in the NRPPa message (that is, an NRPPa measurement request), but is not limited to this. The second positioning request message can also be other types of messages, which is not limited in the embodiments of the present disclosure.

[0366] In some embodiments, the third indication information can indicate the second frequency layer through any one of the following items: frequency point number; reference frequency point; common reference point; frequency layer index; frequency layer identifier; second positioning reference signal resource set identifier (SRS resource set ID); second positioning reference signal resource identifier.

[0367] The reference frequency point may be NR-ARFCN, but is not limited thereto. The reference frequency point may also be other types, which is not limited in the embodiments of the present disclosure.

[0368] Optionally, the third indication information may also indicate the fourth frequency layer in other ways, which is not limited in this embodiment of the present disclosure.

[0369] In some embodiments, the positioning measurement result is a CPP-related positioning measurement result, and the access network device may select a frequency layer from multiple third frequency layers as the fourth frequency layer based on the third indication information.

[0370] The introduction of the positioning measurement results related to CPP can be found in the above embodiment and will not be repeated here.

[0371] For example, the access network device may select a fourth frequency layer for measuring RSCP and / or RSCPD from multiple third frequency layers according to an instruction of the core network device.

[0372] In some embodiments, the positioning measurement result is a non-time-related and / or non-CPP-related positioning measurement result, and the access network device can select at least one third frequency layer from multiple third frequency layers as the fourth frequency layer based on the third indication information.

[0373] The introduction of the non-time-related positioning measurement results and the non-CPP-related positioning measurement results can be found in the above embodiments, which will not be repeated here.

[0374] For example, the access network device may select at least one fourth frequency layer for measuring at least one of RSRP, RSRPP, and UL AOA from multiple third frequency layers according to an instruction of the core network device.

[0375] In step S2203, the access network device measures the second positioning reference signal on the fourth frequency layer to obtain a positioning measurement result.

[0376] In some embodiments, after determining the fourth frequency layer from multiple third frequency layers, the access network device may measure the second positioning reference signal on the fourth frequency layer to obtain a positioning measurement result.

[0377] In some embodiments, the access network device may measure the second positioning reference signal on a fourth frequency layer determined from the plurality of third frequency layers to obtain a CPP-related positioning measurement result.

[0378] For example, the access network device may measure the SRS on a fourth frequency layer determined from the multiple third frequency layers to obtain the RSCP and / or RSCPD.

[0379] In some embodiments, the access network device may use each third frequency layer of multiple third frequency layers as a fourth frequency layer, and the access network device may measure the second positioning reference signal on each fourth frequency layer to obtain a CPP-related positioning measurement result.

[0380] For example, the network configures three third frequency layers for the access network device, then the access network device can select each of the three third frequency layers as the fourth frequency layer, that is, three fourth frequency layers are determined, and the access network device can measure the SRS on each fourth frequency layer to obtain RSCP and / or RSCPD, that is, the access network device can obtain three positioning measurement results (that is, RSCP and / or RSCPD), where each fourth frequency layer corresponds to a positioning measurement result.

[0381] In some embodiments, the access network device may measure the second positioning reference signal on at least one fourth frequency layer determined from the plurality of third frequency layers to obtain a non-time-related and / or non-CPP-related positioning measurement result.

[0382] For example, the access network device may measure the SRS on at least one fourth frequency layer determined from the multiple third frequency layers to obtain at least one of RSRP, RSRPP, and UL AOA.

[0383] In some embodiments, the access network device may measure the second positioning reference signal according to the bandwidth aggregation configuration of the second positioning reference signal to obtain a non-CPP related positioning measurement result.

[0384] For example, the access network device may measure the SRS according to the bandwidth aggregation configuration of the SRS to obtain RSRP and / or RSRPP.

[0385] Step S2204: The access network device sends the positioning measurement result to the core network device.

[0386] It should be noted that, in the case where the access network device determines the fourth frequency layer according to the instructions of the core network device, the fourth frequency layer determined by the access network device itself is indicated by the core network device. Therefore, the core network device already knows the frequency layer on which the access network device measures the second positioning reference signal. Therefore, the access network device directly sends the positioning measurement results obtained on the fourth frequency layer to the core network device.

[0387] In the case where the access network device selects the fourth frequency layer by itself, the access network device can send fourth indication information to the core network device, where the fourth indication information is used to indicate the fourth frequency layer, so that the core network device can perform terminal positioning according to the fourth frequency layer indicated by the fourth indication information.

[0388] In some embodiments, the access network device may send a second positioning response message to the core network device, and the second positioning response message may include fourth indication information to implement the sending of the fourth indication information.

[0389] Among them, the second positioning response message can be an NRPPa message. For example, the second positioning response message can be a measurement report message (that is, NRPPa measurement report) or a measurement update message (that is, NRPPa measurement update) in the NRPPa message, but is not limited to this. The second positioning response message can also be other types of messages, which is not limited in the embodiments of the present disclosure.

[0390] In some embodiments, the fourth indication information can indicate the fourth frequency layer through any one of the following items: frequency point number; reference frequency point; common reference point; frequency layer index; frequency layer identifier; second positioning reference signal resource set identifier; second positioning reference signal resource identifier frequency point number; bandwidth aggregation identifier.

[0391] The reference frequency point may be NR-ARFCN, but is not limited thereto. The reference frequency point may also be other types, which is not limited in the embodiments of the present disclosure.

[0392] Optionally, the fourth indication information may also indicate the fourth frequency layer in other ways, which is not limited in this embodiment of the present disclosure.

[0393] Step S2205: The core network device obtains the positioning measurement result.

[0394] In some embodiments, the core network device may receive the positioning measurement result sent by the access network device to obtain the positioning measurement result measured by the access network device on the fourth frequency layer.

[0395] It should be noted that, in the case where the access network device determines the fourth frequency layer according to the instructions of the core network device, the second frequency layer determined by the access network device is itself indicated by the core network device. Therefore, the core network device already knows the frequency layer on which the access network device measures the second positioning reference signal. Therefore, in this case, the core network device only needs to receive the positioning measurement results obtained by the access network device on the fourth frequency layer.

[0396] In the case where the access network device selects the fourth frequency layer by itself, the access network device will also send fourth indication information to the core network device to indicate the fourth frequency layer. Therefore, in some embodiments, the core network device can also receive the fourth indication information sent by the access network device to determine the frequency layer used by the access network device to measure the second positioning reference signal based on the fourth frequency layer indicated by the fourth indication information.

[0397] In some embodiments, the core network device may receive a second positioning response message sent by the access network device. The second positioning response message may include fourth indication information, so that the core network device can obtain the fourth indication information. For an introduction to the second response message and the fourth indication information, refer to the above embodiment and are not further described here.

[0398] It should be noted that the frequency layer involved in the embodiments of the present disclosure may also be a BWP or a carrier, but is not limited thereto, and the embodiments of the present disclosure are not limited thereto.
