[0136] In one possible implementation, the second sub-node may first process the positioning measurement result, and then send the processed positioning result to the first sub-node as input information of the AI model.
[0137] Step S202: The first node sends a first message to the second node.
[0138] In some embodiments, the second node receives the first message sent by the first node.
[0139] In some embodiments, the first message may include first information, which may be used to indicate the AI-assisted positioning measurement result.

The second node performs AI model inference based on the input information of the AI model to obtain output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0143] The communication method involved in the embodiments of the present disclosure may include at least one of steps S201 to 202. For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and steps S201+S202 may be implemented as independent embodiments, but are not limited thereto.
[0144] In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.
[0145] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
[0146] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or replaced in different embodiments.
[0147] In some embodiments, reference may be made to other optional embodiments described before or after the description corresponding to FIG. 2 .
[0148] In some embodiments, for the Next Generation Radio Access Network (NG-RAN), three artificial intelligence (AI)-based positioning architectures can be considered: AI-assisted positioning, where the AI model is deployed on distributed nodes; AI-assisted positioning, where the AI model is deployed on centralized nodes; and direct UE positioning.
[0149] It should be noted that the AI model involved in this disclosure can also be described as a machine learning model (ML Model), model, etc., and this disclosure does not specifically limit this.
[0150] In one possible implementation, Figure 3A is a schematic diagram of an AI-assisted positioning architecture according to an embodiment of the present disclosure, wherein the AI model is deployed on a centralized node (e.g., a gNB-CU).
[0151] As shown in Figure 3A, in a Central Unit-Distributed Unit (CU-DU) split architecture, an AI model can be deployed on the gNB-CU. Each distributed node (e.g., a gNB-DU) can have one or more Transmission and Receiving Points (TRPs). Measurement results from multiple TRPs (multi-TRPs) serve as input to the same or identical AI model deployed on the gNB-CU. The AI model performs inference based on the input information and outputs inference results.
[0152] It's important to note that in a CU-DU separation architecture, the CU and DU are physically separated and deployed in different entities. In traditional wireless communication networks, the CU and DU are typically integrated into a single entity (such as a base station). By separating the CU and DU, the CU can centrally handle control plane tasks, optimizing network resources. At the same time, the DU can be closer to the terminal, reducing signal transmission latency. Therefore, the CU-DU separation architecture improves network performance, scalability, and reliability, laying the foundation for next-generation wireless communication networks such as 5G and 6G.
[0153] In another possible implementation, Figure 3B is a schematic diagram of another AI-assisted positioning architecture according to an embodiment of the present disclosure, wherein the AI model is deployed on a centralized node (e.g., a location management function (LMF)).
[0154] As shown in Figure 3B, in a CU-DU split architecture, the AI model can be deployed on the LMF. Each distributed node (e.g., gNB-DU) can have one or more Transmission Reception Points (TRPs). Measurement results from multiple transmission reception points (multi-TRPs) are applied as input to the same AI model deployed on the LMF. The AI model can perform inference based on the input information and output the inference results.
[0155] It should be noted that the “AI model deployed on a centralized node” involved in this disclosure can also be described as “the AI model is centrally deployed on the node”, “an AI model is deployed on the centralized node”, “one or more AI models are deployed on the centralized node”, etc. This disclosure does not impose any restrictions on this.
[0156] However, there are still some technical problems. For example, when the AI model is deployed on a centralized node, how to implement AI-assisted positioning measurement, how to support the positioning measurement results on multiple different TRPs as input to the AI model deployed on the centralized node, etc.
[0157] In a first aspect, embodiments of the present disclosure provide a positioning measurement method. Figure 4 is a schematic flow chart illustrating a positioning measurement method according to an embodiment of the present disclosure. The positioning measurement method illustrated in this embodiment may be executed by a first node.
[0158] In some embodiments, the first node may include an access network node, and the second node may include a core network node.
[0159] For example, as shown in Figure 3A, the first node may be a Next Generation Radio Access Network node (NG-RAN node), and the second node may be a Location Management Function (LMF); wherein an AI model is deployed on the NG-RAN node.
[0160] For another example, as shown in FIG3B , the first node may be an NG-RAN node, and the second node may be an LMF; wherein an AI model is deployed on the LMF.
[0161] In some embodiments, the first node may include a first sub-node and a second sub-node, wherein the first sub-node may include a centralized unit in the access network node, and the second sub-node may include a distributed unit in the access network node.
[0162] For example, as shown in Figure 3A, the NG-RAN node may include gNB-CU and distributed nodes such as gNB-DU1 and gNB-DU2; among which, an AI model is deployed on the gNB-CU.
[0163] It should be noted that the “first node”, “second node”, “first sub-node” and “second sub-node” can distinguish different nodes participating in the positioning measurement process, and do not represent any special limitation on the present disclosure.
[0164] As shown in FIG4 , the positioning measurement method may include the following steps:
[0165] In step S401 , it is determined to use AI-assisted positioning measurement.
[0166] In step S402, a first message is sent to the second node, where the first message includes first information, and the first information is used to indicate an AI-assisted positioning measurement result.
[0167] For example, the NG-RAN node may determine to use AI-assisted positioning measurement; further, the NG-RAN node may send a measurement feedback message based on the New Radio Positioning Protocol A (NR Positioning Protocol A, NRPPa) to the LMF, wherein the measurement feedback message based on NRPPa may include first information, and the first information is used to indicate the AI-assisted positioning measurement result.
[0168] The NRPPa-based measurement feedback message may specifically include but is not limited to: an NRPPa measurement response message, an NRPPa measurement report message, an NRPPa AI positioning measurement feedback message, an NRPPa AI positioning measurement report message, and the like.
[0169] It should be noted that the embodiment shown in FIG. 4 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0170] Optionally, the second node may receive a first message sent by the first node, wherein the first message includes first information, and the first information is used to indicate an AI-assisted positioning measurement result.
[0171] According to an embodiment of the present disclosure, after determining to use AI-assisted positioning measurement, the first node can indicate the AI-assisted positioning measurement result to the second node by sending a first message to the second node. Accordingly, when the AI model is deployed on a centralized node, it can support the input of positioning measurement results obtained on multi-TRP into the AI model and obtain the inference result output by the AI model, thereby realizing AI-assisted positioning measurement, and then the terminal's position can be calculated based on the AI-assisted positioning result, which is conducive to improving the accuracy of terminal positioning.
[0172] In some embodiments, in step S401, the first node may determine to use AI-assisted positioning measurement according to an instruction of the second node, or may determine AI-assisted positioning measurement based on its own implementation.
[0173] In one possible implementation, the second node may decide to use AI-assisted positioning measurement. In this case, the determination to use AI-assisted positioning measurement may include: receiving a second message sent by the second node, wherein the second message includes second information, and the second information is used to request AI-assisted positioning measurement; and determining to use AI-assisted positioning measurement based on the second information.
[0174] Optionally, the second node sends a second message to the first node, wherein the second message includes second information, and the second information is used to request AI-assisted positioning measurement.
[0175] The second message may specifically include but is not limited to: NRPPa measurement request message, NRPPa measurement request message, NRPPa AI measurement request message, etc.
[0176] The second information may be, for example, AI-assisted positioning measurement request information (AI-assisted POS request).
[0177] The second information may include at least one of the following: an AI-assisted positioning measurement indicator; positioning measurement requirement information, used to request input information of the AI model.
[0178] For example, the LMF may decide to use AI-assisted positioning measurement and may send a second message to the NG-RAN node, wherein the second message may include an AI-assisted positioning measurement indication and / or positioning measurement requirement information; further, the NG-RAN node may receive the second message sent by the LMF and may determine to use AI-assisted positioning measurement based on the AI-assisted positioning measurement indication and / or positioning measurement requirement information.
[0179] In the above embodiment, the LMF may only send the AI-assisted positioning measurement indication to the NG-RAN node, and the NG-RAN node may determine the input requirements of the AI model on its own. Alternatively, the LMF may directly send the input requirements of the AI model to the NG-RAN node.
[0180] In some other possible implementations, the first node (e.g., gNB-CU) may decide to use AI-assisted positioning measurement. In this case, the determination to use AI-assisted positioning measurement includes: determining to use AI-assisted positioning measurement based on implementation.
[0181] It should be noted that the "determining the use of AI-assisted positioning measurements based on implementation" referred to in this disclosure can also be described as "determining the use of AI-assisted positioning measurements based on at least one of the following information: configuration in the node; computing power of the node; energy consumption of the node; or load of the node." The configuration in the node can be pre-configured or configured by Operation Administration and Maintenance (OAM).
[0182] For example, the gNB-CU can determine whether to use AI-assisted positioning measurements based on the Operation Administration and Maintenance (OAM) configuration.
[0183] Optionally, the second node may send a third message to the first node, the third message including third information, the third information being used to request a traditional positioning measurement. The first node may receive the third message sent by the second node and determine, based on the third information, that positioning measurements need to be performed. Furthermore, the first node may determine, based on the OAM configuration, to use AI-assisted positioning measurements.
[0184] The third message may specifically include but is not limited to: an NRPPa measurement request message, an NRPPa measurement request message, etc. The third message does not include an AI-assisted positioning measurement indication and / or positioning measurement requirement information.
[0185] In some embodiments, the positioning measurement requirement information may include at least one of the following: a requested TRP identifier; an AI model identifier; a channel impulse response (CIR) measurement request; a power delay profile (PDP) measurement request; a delay profile (DP) measurement request; or a traditional positioning measurement request.
[0186] Among them, the requested TRP identifier is used to indicate the TRP requested among multiple TRPs. The AI model identifier can be used to indicate the AI model to which the requested positioning measurement result is applied. The DP measurement request may include configured threshold information, and the threshold information may be absolute threshold information or relative threshold information. Traditional positioning measurement requests may specifically include but are not limited to: base station transmit and receive time difference (gNB-RxTxTimeDiff) measurement request, uplink sounding reference signal received power (UL-SRS-RSRP) measurement request, uplink arrival angle (Uplink Angles of Arrival, UL-AoA) measurement request, uplink relative arrival time (Uplink Relative Time of Arrival, UL-RTOA) measurement request, multiple uplink arrival angles (Multiple UL-AoA) measurement request, uplink sounding reference signal reference signal received path power (UL SRS Reference Signal Received Path Power, UL SRS-RSRPP) measurement request, etc.
[0187] In some embodiments, the input information (AI input) of the AI model may include at least one of the following: TRP identifier; AI model identifier; CIR measurement result; PDP measurement result; DP measurement result; traditional positioning measurement result.
[0188] The TRP identifier is used to indicate that the input information of the AI model comes from a specific TRP among multiple TRPs. The AI model identifier is used to indicate that the input information of the AI model is for a specific AI model. The CIR measurement result may include time information, amplitude information (including real and imaginary amplitude information), and / or phase information corresponding to the sampling point. The PDP measurement result may include sampling time information and / or amplitude information. The DP measurement result may include time information and / or threshold information, where the threshold information may be absolute threshold information or relative threshold information. Traditional positioning measurement results may specifically include, but are not limited to: gNB-RxTxTimeDiff measurement result, UL-SRS-RSRP measurement result, UL-AoA measurement result, UL-RTOA measurement result, multiple UL-AoA measurement result, UL SRS-RSRPP measurement result, etc.
[0189] In some embodiments, before step S402, the method may further include: determining positioning measurement requirement information, wherein the positioning measurement requirement information is used to request input information of the AI model; performing positioning measurement according to the positioning measurement requirement information to obtain input information of the AI model.
[0190] In some possible implementations, the first node may determine the positioning measurement requirement information based on an instruction from the second node. In this case, the method for determining the positioning measurement requirement information may include: determining the positioning measurement requirement information based on second information in a second message sent by the second node.
[0191] For example, the NG-RAN node can receive a second message sent by the LMF, and the second message includes positioning measurement requirement information. The NG-RAN node can perform positioning measurement according to the positioning measurement requirement information included in the second message to obtain input information of the AI model.
[0192] In some other possible implementations, the first node may determine the positioning measurement requirement information based on its own implementation. In this case, the manner of determining the positioning measurement requirement information includes: determining the positioning measurement requirement information based on implementation.
[0193] It should be noted that the phrase "determining positioning measurement requirement information based on implementation" in this disclosure can also be described as "determining positioning measurement requirement information based on at least one of the following information: AI model requirements; node configuration." The node configuration can be pre-configured or configured by Operation Administration and Maintenance (OAM).
[0194] For example, the NG-RAN node can receive a second message sent by the LMF, where the second message only includes an AI-assisted positioning measurement indication but does not include positioning measurement requirement information. Alternatively, the NG-RAN node can receive a third message sent by the LMF and decide to use AI-assisted positioning measurement based on the OAM configuration. The NG-RAN node can then determine the positioning measurement requirement information based on the OAM configuration, and perform positioning measurement based on the positioning measurement requirement information to obtain input information of the AI model.
[0195] In some other possible implementations, the first node may determine the positioning measurement requirement information by combining the two aforementioned methods, which are not further described here. For example, if an AI model is deployed on the gNB-CU, the gNB-CU may not only obtain the first positioning measurement requirement information indicated by the second information in the second message, but may also determine the second positioning measurement requirement information based on its own implementation. The gNB-CU may then adjust the second positioning measurement requirement information based on the first positioning measurement requirement information and request AI model input information from the gNB-DU based on the adjusted second positioning measurement requirement information.
[0196] In some embodiments, under the CU-DU separation architecture, the first node includes a first sub-node and a second sub-node. In this case, determining the positioning measurement requirement information includes: the first sub-node determines the positioning measurement requirement information and sends the positioning measurement requirement information to the second sub-node; performing positioning measurement according to the positioning measurement requirement information to obtain input information of the AI model includes: the second sub-node performs positioning measurement according to the positioning measurement requirement information, obtains the input information of the AI model, and sends the input information of the AI model to the first sub-node.
[0197] For example, after the gNB-CU determines to use AI-assisted positioning measurement and determines positioning measurement requirement information, it may send a fourth message to the gNB-DU, where the fourth message includes the positioning measurement requirement information; further, the gNB-DU may perform positioning measurement based on the positioning measurement requirement information sent by the gNB-CU to obtain input information for the AI model; further, the gNB-DU may send a fifth message to the gNB-CU, where the fifth message may include input information for the AI model (AI inputs request).
[0198] The fourth message may be an F1AP AI measurement request message, which may specifically include but is not limited to an F1AP measurement request message, etc. The positioning measurement requirement information included in the fourth message may be, for example, AI input request information (AI inputs request).
[0199] The fifth message may be an F1AP AI measurement feedback message, which may specifically include, but is not limited to, an F1AP measurement response message, an F1AP measurement report message, and an F1AP AI measurement report message. In one possible implementation, the gNB-DU may first process the positioning measurement results and then send the processed positioning results as input information to the gNB-CU. For example, the input information to the AI model sent by the gNB-DU to the gNB-CU may be eigenvalues processed by singular value decomposition (SVD), but is not limited thereto.
[0200] In some embodiments, an AI model is deployed on the first node, and the first information includes output information of the AI model; the method further includes: performing AI model reasoning based on the input information of the AI model to obtain output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0201] For example, as shown in Figure 3A, an AI model is deployed on the gNB-CU; the gNB-CU can receive the input information of the AI model sent by the gNB-DU, and can perform AI model inference based on the received AI model input information to obtain the output information (AI outputs) of the AI model; further, the gNB-CU can also use the output information of the AI model as the first information and send a first message including the first information to the LMF; the LMF can calculate the position of the terminal based on the output information of the AI model included in the first message, that is, the LMF can locate the terminal based on the output information of the AI model included in the first message.
[0202] In the above embodiment, the gNB-CU sends positioning measurement request information to the gNB-DU, requesting the gNB-DU to perform corresponding positioning measurements to obtain AI model input information. The gNB-CU then performs AI model inference based on the AI model input information sent by the gNB-DU, obtaining AI model output information. Consequently, when the AI model is deployed on the gNB-CU, it can support inputting positioning measurement results obtained over multi-TRPs into the AI model and obtaining inference results from the AI model output, thereby implementing AI-assisted positioning measurements. The terminal's position can then be calculated based on the AI-assisted positioning results, thereby improving terminal positioning accuracy.
[0203] In some embodiments, an AI model is deployed on the second node, and the first information includes input information of the AI model.
[0204] Optionally, the second node may perform AI model reasoning based on the input information of the AI model to obtain output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0205] For example, as shown in Figure 3B, an AI model is deployed on the LMF; the gNB-CU can receive the input information of the AI model sent by the gNB-DU, and can use the input information of the AI model as the first information to send a first message including the first information to the LMF; the LMF can perform AI model inference based on the input information of the AI model included in the first message to obtain output information of the AI model; the LMF can also calculate the position of the terminal based on the output information of the AI model obtained by inference, that is, the LMF can locate the terminal based on the output information of the AI model.
[0206] In the above embodiment, the gNB-CU can request the gNB-DU to perform corresponding positioning measurements to obtain AI model input information by sending positioning measurement request information to the gNB-DU. The gNB-CU can then feed the AI model input information back to the LMF, allowing the LMF to perform AI model inference based on the AI model input information sent by the gNB-CU and obtain AI model output information. Accordingly, when the AI model is deployed on the LMF, it can support inputting positioning measurement results obtained on multi-TRPs into the AI model and obtaining AI model inference results, thereby implementing AI-assisted positioning measurement. The terminal's position can then be calculated based on the AI-assisted positioning results, which helps improve terminal positioning accuracy.
[0207] In a second aspect, embodiments of the present disclosure provide a positioning measurement method. Figure 5 is a schematic flow chart illustrating another positioning measurement method according to an embodiment of the present disclosure. The positioning measurement method illustrated in this embodiment may be executed by a second node.
[0208] As shown in FIG5 , the positioning measurement method may include the following steps:
[0209] In step S501, a first message sent by a first node is received, where the first message includes first information, and the first information is used to indicate an AI-assisted positioning measurement result.
[0210] For example, the first node may be an NG-RAN node, and the second node may be an LMF; the LMF may receive an NRPPa-based measurement feedback message sent by the NG-RAN node, wherein the NRPPa-based measurement feedback message may include first information, and the first information is used to indicate the AI-assisted positioning measurement result.
[0211] The NRPPa-based measurement feedback message may specifically include but is not limited to: an NRPPa measurement response message, an NRPPa measurement report message, an NRPPa AI positioning measurement feedback message, an NRPPa AI positioning measurement report message, and the like.
[0212] In some embodiments, the AI model can be deployed on a centralized node, for example, the AI model can be deployed on a gNB-CU or LMF.
[0213] It should be noted that the embodiment shown in FIG. 5 can be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific selection can be made as needed and the present disclosure does not limit it.
[0214] Optionally, the first node may determine to use AI-assisted positioning measurements.
[0215] Optionally, the first node may send a first message to the second node, wherein the first message includes first information, and the first information is used to indicate the AI-assisted positioning measurement result.
[0216] According to an embodiment of the present disclosure, after determining to use AI-assisted positioning measurement, the first node can indicate the AI-assisted positioning measurement result to the second node by sending a first message to the second node. Accordingly, when the AI model is deployed on a centralized node, it can support the input of positioning measurement results obtained on multi-TRP into the AI model and obtain the inference result output by the AI model, thereby realizing AI-assisted positioning measurement, and then the terminal's position can be calculated based on the AI-assisted positioning result, which is conducive to improving the accuracy of terminal positioning.
[0217] In some embodiments, the first node may determine to use AI-assisted positioning measurement based on an instruction from the second node, or may determine AI-assisted positioning measurement based on its own implementation.
[0218] In one possible implementation, the second node may decide to use AI-assisted positioning measurement. In this case, the method further includes: sending a second message to the first node, wherein the second message includes second information, and the second information is used to request AI-assisted positioning measurement.
[0219] Optionally, the first node may receive a second message sent by the second node, wherein the second message includes second information, and the second information is used to request AI-assisted positioning measurement.
[0220] The second message may specifically include but is not limited to: NRPPa measurement request message, NRPPa measurement request message, NRPPa AI measurement request message, etc.
[0221] The second information may be, for example, AI-assisted positioning measurement request information (AI-assisted POS request).
[0222] The second information may include at least one of the following: an AI-assisted positioning measurement indicator; positioning measurement requirement information, used to request input information of the AI model.
[0223] For example, the LMF may decide to use AI-assisted positioning measurement and may send a second message to the NG-RAN node, wherein the second message may include an AI-assisted positioning measurement indication and / or positioning measurement requirement information; further, the NG-RAN node may receive the second message sent by the LMF and may determine to use AI-assisted positioning measurement based on the AI-assisted positioning measurement indication and / or positioning measurement requirement information.
[0224] In the above embodiment, the LMF may only send the AI-assisted positioning measurement indication to the NG-RAN node, and the NG-RAN node may determine the input requirements of the AI model on its own. Alternatively, the LMF may directly send the input requirements of the AI model to the NG-RAN node.
[0225] In some other possible implementations, the decision to use AI-assisted positioning measurements may be made by a first node (e.g., a gNB-CU), and the first node is expected to determine the use of AI-assisted positioning measurements based on the implementation. For example, the gNB-CU may determine the use of AI-assisted positioning measurements based on an OAM configuration. In this case, the method may further include: sending a third message to the first node, the third message including third information, the third information being used to request a traditional positioning measurement.
[0226] Optionally, the first node may receive a third message sent by the second node, and determine that positioning measurement needs to be performed based on the third information, and the first node may determine to use AI-assisted positioning measurement based on the configuration of OAM.
[0227] The third message may specifically include but is not limited to: an NRPPa measurement request message, an NRPPa measurement request message, etc. The third message does not include an AI-assisted positioning measurement indication and / or positioning measurement requirement information.
[0228] In some embodiments, the positioning measurement requirement information may include at least one of the following: a requested TRP identifier; an AI model identifier; a CIR measurement request; a PDP measurement request; a DP measurement request; or a traditional positioning measurement request.
[0229] The requested TRP identifier is used to indicate the requested TRP among multiple TRPs. The AI model identifier can be used to indicate the AI model to which the requested positioning measurement result is applied. The DP measurement request may include configured threshold information, which may be absolute threshold information or relative threshold information. Traditional positioning measurement requests may specifically include, but are not limited to: gNB-RxTxTimeDiff measurement request, UL-SRS-RSRP measurement request, UL-AoA measurement request, UL-RTOA measurement request, Multiple UL-AoA measurement request, UL SRS-RSRPP measurement request, etc.
[0230] In some embodiments, the input information of the AI model (AI inputs) may include at least one of the following: TRP identifier; AI model identifier; CIR measurement result; PDP measurement result; DP measurement result; traditional positioning measurement result.
[0231] The TRP identifier is used to indicate that the input information of the AI model comes from a specific TRP among multiple TRPs. The AI model identifier is used to indicate that the input information of the AI model is for a specific AI model. The CIR measurement result may include time information, amplitude information (including real and imaginary amplitude information), and / or phase information corresponding to the sampling point. The PDP measurement result may include sampling time information and / or amplitude information. The DP measurement result may include time information and / or threshold information, where the threshold information may be absolute threshold information or relative threshold information. Traditional positioning measurement results may specifically include, but are not limited to: gNB-RxTxTimeDiff measurement result, UL-SRS-RSRP measurement result, UL-AoA measurement result, UL-RTOA measurement result, multiple UL-AoA measurement result, UL SRS-RSRPP measurement result, etc.
[0232] Optionally, the first node may determine positioning measurement requirement information. The first node may also perform positioning measurement according to the positioning measurement requirement information to obtain input information of the AI model.
[0233] In some possible implementations, the first node may determine the positioning measurement requirement information according to an instruction of the second node. In this case, the first node may determine the positioning measurement requirement information according to second information in a second message sent by the second node.
[0234] For example, the NG-RAN node can receive a second message sent by the LMF, and the second message includes positioning measurement requirement information. The NG-RAN node can perform positioning measurement according to the positioning measurement requirement information included in the second message to obtain input information of the AI model.
[0235] In some other possible implementations, the first node may determine the positioning measurement requirement information based on its own implementation. In this case, the first node may determine the positioning measurement requirement information based on the implementation.
[0236] For example, the NG-RAN node can receive a second message sent by the LMF, where the second message only includes an AI-assisted positioning measurement indication but does not include positioning measurement requirement information. Alternatively, the NG-RAN node can receive a third message sent by the LMF and decide to use AI-assisted positioning measurement based on the OAM configuration. The NG-RAN node can then determine the positioning measurement requirement information based on the OAM configuration, and perform positioning measurement based on the positioning measurement requirement information to obtain input information of the AI model.
[0237] In some embodiments, under the CU-DU separation architecture, the first node includes a first sub-node and a second sub-node. In this case, the first sub-node determines positioning measurement requirement information and sends the positioning measurement requirement information to the second sub-node; the second sub-node performs positioning measurement according to the positioning measurement requirement information, obtains input information of the AI model, and sends the input information of the AI model to the first sub-node.
[0238] For example, after the gNB-CU determines to use AI-assisted positioning measurement and determines the positioning measurement requirement information, it can send the positioning measurement requirement information to the gNB-DU. Furthermore, the gNB-DU can perform positioning measurement based on the positioning measurement requirement information sent by the gNB-CU to obtain input information for the AI model. Furthermore, the gNB-DU can send the input information for the AI model to the gNB-CU.
[0239] In one possible implementation, the gNB-DU may first process the positioning measurement results and then send the processed positioning results to the gNB-CU as input to the AI model. For example, the input to the AI model sent by the gNB-DU to the gNB-CU may be eigenvalues processed by SVD, but is not limited to this.
[0240] In some embodiments, an AI model is deployed on the first node, and the first information includes output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0241] Optionally, the first node may perform AI model reasoning based on the input information of the AI model to obtain output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0242] For example, as shown in Figure 3A, an AI model is deployed on the gNB-CU; the gNB-CU can receive the input information of the AI model sent by the gNB-DU, and can perform AI model inference based on the received AI model input information to obtain the output information (AI output) of the AI model; further, the gNB-CU can also use the output information of the AI model as the first information and send a first message including the first information to the LMF; the LMF can calculate the position of the terminal based on the output information of the AI model included in the first message, that is, the LMF can locate the terminal based on the output information of the AI model included in the first message.
[0243] In the above embodiment, the gNB-CU sends positioning measurement request information to the gNB-DU, requesting the gNB-DU to perform corresponding positioning measurements to obtain AI model input information. The gNB-CU then performs AI model inference based on the AI model input information sent by the gNB-DU, obtaining AI model output information. Consequently, when the AI model is deployed on the gNB-CU, it can support inputting positioning measurement results obtained over multi-TRPs into the AI model and obtaining inference results from the AI model output, thereby implementing AI-assisted positioning measurements. The terminal's position can then be calculated based on the AI-assisted positioning results, thereby improving terminal positioning accuracy.
[0244] In some embodiments, an AI model is deployed on the second node, and the first information includes input information of the AI model. In this case, the method further includes: performing AI model reasoning based on the input information of the AI model to obtain output information of the AI model, and the output information of the AI model is used to locate the terminal.
[0245] For example, as shown in Figure 3B, an AI model is deployed on the LMF; the gNB-CU can receive the input information of the AI model sent by the gNB-DU, and can use the input information of the AI model as the first information to send a first message including the first information to the LMF; the LMF can perform AI model inference based on the input information of the AI model included in the first message to obtain output information of the AI model; the LMF can also calculate the position of the terminal based on the output information of the AI model obtained by inference, that is, the LMF can locate the terminal based on the output information of the AI model.
[0246] In the above embodiment, the gNB-CU can request the gNB-DU to perform corresponding positioning measurements to obtain AI model input information by sending positioning measurement request information to the gNB-DU. The gNB-CU can then feed the AI model input information back to the LMF, allowing the LMF to perform AI model inference based on the AI model input information sent by the gNB-CU and obtain AI model output information. Accordingly, when the AI model is deployed on the LMF, it can support inputting positioning measurement results obtained on multi-TRPs into the AI model and obtaining AI model inference results, thereby implementing AI-assisted positioning measurement. The terminal's position can then be calculated based on the AI-assisted positioning results, which helps improve terminal positioning accuracy.
