[0128] The widespread adoption of 5G technology is bringing tremendous changes to every aspect of our lives. According to the International Telecommunication Union (ITU), 5G will permeate every aspect of future society, building a comprehensive, user-centric information ecosystem. 5G user experience rates can reach 100 megabits per second (Mbit / s) to 1 gigabit per second (Gbit / s), enabling premium services like mobile virtual reality. 5G peak rates can reach 10 Gbit / s to 20 Gbit / s, with traffic density reaching 10 megabits per second per square meter (Mbit / s / m²), supporting a thousand-fold increase in mobile traffic. 5G connection density can reach 1 million per square meter (m²), effectively supporting massive IoT devices. 5G transmission latency can reach milliseconds, meeting the stringent requirements of connected vehicles and industrial control. 5G can support speeds of 500 kilometers per hour (km / h), ensuring a superior user experience even in high-speed rail environments. It is foreseeable that 5G, as a representative of new infrastructure, will reshape the future information society.

[0129] In recent years, AI technology has achieved continuous breakthroughs in numerous fields. The continued development of fields like intelligent voice and computer vision has not only brought a rich variety of applications to smart terminals, but has also found widespread application in education, transportation, home furnishings, healthcare, retail, security, and other fields. While bringing convenience to people's lives, it is also promoting industrial upgrading across various industries. AI technology is also rapidly interpenetrating with other disciplines. Its development integrates knowledge from different disciplines while also providing new directions and methods for their development.

[0130] In wireless AI research, application cases of artificial intelligence include: AI-based CSI enhancement; AI-based beam management; and AI-based positioning.

[0131] In traditional positioning scenarios, a positioning method is configured by a location management function (LMF) to a terminal or a base station.

[0132] With the development of artificial intelligence (AI) technology, positioning can now be performed based on AI models. AI models can be deployed in terminals, base stations, and LMFs.

[0133] For example, the following five deployment methods are included but not limited to:

[0134] For example, AI / machine learning (ML) directly targets:

[0135] 1) UE-based positioning: the model is deployed on the UE side, and AI / ML directly locates;

[0136] 2) UE-assisted LMF-based positioning, the model is deployed on the LMF side, and AI / ML directly locates;

[0137] 3) Next generation radio access network (NG-RAN) node assisted positioning, the model is deployed on the LMF side, and AI / ML directly locates.

[0138] Another example is AI / ML-assisted positioning:

[0139] 4) UE-assisted LMF-based positioning, the model is deployed on the UE side, and AI / ML assists positioning;

[0140] 5) NG-RAN node-assisted positioning: the model is deployed on the next generation NodeB (gNB) side, and AI / ML assists in positioning.

[0141] AI / ML direct positioning can be understood as the AI ​​or ML model outputting location information, that is, obtaining positioning results. AI / ML assisted positioning can be understood as the AI ​​or ML model outputting intermediate parameters for positioning, which can be used to calculate location information. In other words, the AI ​​or ML model does not directly obtain positioning results.

[0142] For 1) and 4), the model is deployed on the terminal side, and the terminal uses the AI ​​model to calculate the terminal's coordinates or intermediate parameters used to calculate the terminal's coordinates, such as arrival time, angle information, line of sight (LoS) or non-line of sight (NLoS). During this process, the terminal may need to report the output information of the AI ​​model to the LMF, such as the coordinates calculated by the AI, or the time, angle, and LoS / NLoS information calculated based on the AI.

[0143] For 2), the model is deployed in LMF. During this process, the terminal needs to report the measurement parameters of the positioning reference signal to the LMF.

[0144] For 5), the model is deployed on the base station side. The base station uses the AI ​​model to calculate the intermediate parameters of the terminal coordinates, such as arrival time, and then reports this parameter to the LMF.

[0145] For 3), the model is deployed in LMF. During this process, the base station needs to report the measurement parameters of the positioning reference signal to the LMF.

[0146] In addition, due to the problem of generalization, AI-based operations are difficult to play their advantages in all scenarios. Therefore, in order to ensure the performance of AI-based operations, it is necessary to monitor the performance of AI operations and determine whether to activate a certain AI model, shut down a certain AI model, or switch AI models based on the monitoring results. Among them, AI-based operations, that is, AI operations, can be, for example, AI-based positioning.

[0147] In traditional non-AI operations, the positioning method used by the terminal or base station is generally configured by LMF.

[0148] In some embodiments, for AI-based positioning, when the AI ​​model is deployed on the terminal side or the base station side, if the LMF detects a performance degradation of the AI ​​model, it can configure non-AI positioning parameters for the terminal or base station where the AI ​​model is deployed. However, the LMF configuration of non-AI positioning parameters is time-consuming. If the performance of the AI ​​model degrades dramatically during this process, continuing to use the AI ​​model for positioning may result in positioning failure or inaccurate positioning results.

[0149] Therefore, the present disclosure provides a positioning method, in which a first device receives configuration information of an AI positioning method and configuration information of a non-AI positioning method sent by a second device, so that when the performance of the AI ​​model drops sharply, the configuration information of the non-AI positioning can be directly used for non-AI positioning, thereby avoiding positioning failure or inaccurate positioning.

[0161] FIG2 is a schematic diagram illustrating an interaction of a positioning method according to an embodiment of the present disclosure. As shown in FIG2 , an embodiment of the present disclosure relates to a positioning method for a communication system 100, the method comprising:

[0162] In step S2101 , the second device 102 sends configuration information of a first positioning method and configuration information of a second positioning method to the first device 101 .

[0163] In some embodiments, the first device 101 receives configuration information of a first positioning method and configuration information of a second positioning method sent by the second device 102. The first positioning method is an AI-based positioning method, and the second positioning method is a non-AI-based positioning method.

[0164] In some embodiments, the non-AI based positioning method includes at least one of the following: a positioning method based on downlink angle-of-departure (DL-AoD); a positioning method based on downlink time difference of arrival (DL-TDOA); a positioning method based on exclusive chip identity (ECID); and a positioning method based on assisted global navigation satellite system (A-GNSS).

[0165] In some embodiments, the configuration information of the first positioning method may include at least one of the following: indication information for direct positioning based on the AI ​​model, direct positioning indicates that the output result of the AI ​​model is location information; indication information for indirect positioning based on the AI ​​model, indirect positioning indicates that the output result of the AI ​​model is an intermediate parameter for calculating location information; configuration information of the reference signal used by the first positioning method; configuration information for the first positioning method to report the positioning results.

[0166] Optionally, the configuration information of the first positioning method may include instruction information for direct positioning based on an AI model. Direct positioning based on an AI model means that the AI ​​model directly outputs location information. The configuration information of the first positioning method may instruct the first device to directly obtain location information using the AI ​​model.

[0167] Optionally, the configuration information of the first positioning method may include instruction information for indirect positioning based on an AI model. Indirect positioning based on an AI model means that the AI ​​model outputs intermediate parameters for calculating location information. The first device may calculate the location information based on the output result of the AI ​​model.

[0168] Optionally, the configuration information of the first positioning method may include the configuration information of the reference signal used by the first positioning method. In the process of positioning based on the AI ​​model, it is necessary to measure the reference signal to obtain measurement data. The measurement data includes, for example, the reference signal received power (RSRP), the angle of arrival (AOA) of the reference signal, the Rx-Tx Time Difference of the reference signal, etc., which are not listed one by one in this disclosure. The measurement data of the reference signal can be used to input into the AI ​​model for positioning. The second device can indicate the configuration information of the reference signal to the first device in the configuration information of the first positioning method. For example, the configuration information of the reference signal may include the frequency domain resources, time domain resources, beam information for receiving the reference signal, etc. corresponding to the reference signal. This disclosure does not give examples one by one, but is not limited to this.

[0169] Optionally, the configuration information of the first positioning method may include configuration information for reporting the positioning result by the first positioning method. For example, the configuration information for reporting the positioning result may include whether it is necessary to report an additional path, such as whether to report the arrival time of the additional path and other information. For another example, the configuration information for reporting the positioning result may include the granularity of the reported time information. The granularity of the time information represents the unit corresponding to the time information. Different granularities correspond to different absolute time lengths. For another example, the configuration information for reporting the positioning result may include whether it is necessary to report LoS / NLoS information. For another example, the configuration information for reporting the positioning result may include whether it is necessary to report power information, etc. The above examples in the present disclosure are merely exemplary and are not limited thereto.

[0170] In some embodiments, the configuration information of the second positioning method may include at least one of the following: configuration information of a reference signal used by the second positioning method for positioning; and configuration information for reporting positioning results by the second positioning method.

[0171] Optionally, the configuration information of the second positioning method may include configuration information of a reference signal used by the second positioning method. For details, please refer to the example corresponding to the configuration information of the first positioning method, which is not described in detail in this disclosure. The configuration information of the reference signal used by the first positioning method and the configuration information of the reference signal used by the second positioning method may be the same or different.

[0172] Optionally, the configuration information of the second positioning method may include configuration information for reporting positioning results by the second positioning method. For details, please refer to the example corresponding to the configuration information for reporting positioning results by the first positioning method, which is not further described in this disclosure. The configuration information for reporting positioning results by the first positioning method and the configuration information for reporting positioning results by the second positioning method may be the same or different.

[0173] Step S2102 : The second device 102 sends first information to the first device 101 .

[0174] In some embodiments, the first device 101 receives the first information sent by the second device 102 .

[0175] In some embodiments, the first information is used to indicate the use of the first positioning method and / or the second positioning method for positioning. It is understood that when the second device sends configuration information for the first positioning method and configuration information for the second positioning method to the first device, the first device may be unable to determine whether to use the first positioning method or the second positioning method for positioning. Therefore, the second device may send the first information to the first device to instruct the first device to use the first positioning method and / or the second positioning method for positioning.

[0176] Optionally, the first information may indicate that a first positioning method is used for positioning, and the first device may use the first positioning method for positioning based on configuration information of the first positioning method.

[0177] Optionally, the first information may indicate that a second positioning method is used for positioning, and the first device may use the second positioning method for positioning based on configuration information of the second positioning method.

[0178] Optionally, the first information may indicate that positioning is performed using a first positioning method and a second positioning method. For example, intermediate parameters for positioning may be obtained based on the first positioning method, and then a positioning result may be obtained based on the second positioning method, thereby obtaining the location information. For another example, intermediate parameters for positioning may be obtained based on the second positioning method, and then a positioning result may be obtained based on the first positioning method, thereby obtaining the location information.

[0179] In some embodiments, if the first information indicates the use of a first positioning method and a second positioning method for positioning, the first information may also be used to indicate that the first positioning method is the primary positioning method and the second positioning method is the secondary positioning method. Alternatively, the first information may also be used to indicate that the second positioning method is the primary positioning method and the first positioning method is the secondary positioning method.

[0180] For example, if the first information indicates that the first positioning method is the primary positioning method and the second positioning method is the secondary positioning method, the main positioning process is implemented using the first positioning method, and individual steps can be implemented using the second positioning method. Conversely, if the first information indicates that the first positioning method is the secondary positioning method and the second positioning method is the primary positioning method, the main positioning process is implemented using the second positioning method, and individual steps can be implemented using the first positioning method. For another example, if the first information indicates that the first positioning method is the primary positioning method and the second positioning method is the secondary positioning method, positioning prioritizes the first positioning method. When the first positioning method is not applicable, for example, when the performance of the AI ​​model degrades, the second positioning method is used. Conversely, if the first information indicates that the second positioning method is the primary positioning method and the first positioning method is the secondary positioning method, positioning prioritizes the second positioning method. When the second positioning method is not applicable, the first positioning method is used.

[0181] In some embodiments, the configuration information for the first positioning method and the configuration information for the second positioning method may be carried by the first information. For example, the configuration information for the first positioning method and the configuration information for the second positioning method may be included in two elements of the first information, respectively. The two elements of the first information may be, for example, two information fields of the first information.

[0182] In some embodiments, the configuration information for the first positioning method and the configuration information for the second positioning method may be sent by the second device at once. That is, the two units of the first information may be sent by the second device at once. Alternatively, the configuration information for the first positioning method and the configuration information for the second positioning method may be sent by the second device at two times. That is, the two units of the first information may be sent by the second device at two times.

[0183] In some embodiments, the first information may be a Long Term Evolution Positioning Protocol message, for example, a Request Location Information message.

[0184] In some embodiments, the name of the first information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0185] Step S2103: The first device 101 performs positioning based on the first information.

[0186] In some embodiments, the first device 101 may perform positioning based on the first information. For example, the first positioning method and / or the second positioning method may be used to perform positioning based on an indication of the first information.

[0187] Step S2104 : The first device 101 sends third information to the second device 102 .

[0188] In some embodiments, the second device 102 receives the third information sent by the first device 101 .

[0189] In some embodiments, the third information is used to indicate the positioning result information and the positioning method used to obtain the positioning result information. That is, after positioning, the first device 101 can send the positioning result, such as location information or intermediate parameters used for positioning, to the second device and report the positioning method used for positioning to the second device.

[0190] In some embodiments, the third information may be, for example, an LPP message, which may be, for example, Provide Location Information.

[0191] In some embodiments, the name of the third information is not limited, and it can be, for example, "reporting information" or the like.

[0192] The positioning method involved in the embodiments of the present disclosure may include at least one of steps S2101 to S2104. Each of steps S2101 to S2104 can be implemented as a separate embodiment. The embodiments can be combined in any manner and implemented in a different order, provided they are not in conflict. For example, step S2101 can be implemented as a standalone embodiment, but is not limited thereto.

[0193] In some embodiments, step S2102, step S2103, and step S2104 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0194] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .

[0195] FIG2b is a schematic diagram illustrating an interaction of a positioning method according to an embodiment of the present disclosure. As shown in FIG2b , the present disclosure embodiment relates to a positioning method for a communication system 100, the method comprising:

[0196] In step S2201 , the second device 102 sends configuration information of a first positioning method and configuration information of a second positioning method to the first device 101 .

[0197] The optional implementation of step S2201 can refer to the optional implementation of step S2101 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0198] Step S2202 : The second device 102 sends second information to the first device 101 .

[0199] In some embodiments, the first device 101 receives the second information sent by the second device 102 .

[0200] In some embodiments, the second information represents a determination condition for the first device to use the first positioning method for positioning. For example, the determination condition may be that positioning is performed based on the first positioning method in response to the determination condition represented by the second information being met, and positioning is performed based on the second positioning method in response to the determination condition represented by the second information not being met.

[0201] In some embodiments, the judgment condition may be that when the channel state meets the first threshold value, positioning is performed based on the first positioning method. Conversely, if the channel state does not meet the first threshold value, positioning is performed based on the second positioning method. It can be understood that in the process of positioning based on the AI ​​model, if the channel state is inconsistent with the channel state during the AI ​​model training, the performance of the AI ​​model will decline. Therefore, the first threshold value can be determined based on the channel state during the AI ​​model training. When the channel state meets the first threshold value, it can be considered to be similar to the channel state during the AI ​​model training. At this time, positioning can be performed based on the first positioning method. When the channel state does not meet the first threshold value, it can be considered to be inconsistent with the channel state during the AI ​​model training. At this time, positioning can be performed based on the second positioning method to avoid the impact of the performance degradation of the AI ​​model on the positioning effect.

[0202] In some embodiments, the determination condition may be that when the value of the AI ​​model input data meets the second threshold value, positioning is performed based on the first positioning method. Conversely, if the value of the AI ​​model input data does not meet the second threshold value, positioning is performed based on the second positioning method. It can be understood that in the process of positioning based on the AI ​​model, if the value of the AI ​​model input data is inconsistent with the value of the input data during AI model training, the performance of the AI ​​model will decline. Therefore, the second threshold value can be determined based on the value of the input data during AI model training. When the value of the AI ​​model input data meets the second threshold value, positioning is performed based on the first positioning method. Otherwise, positioning is performed based on the second positioning method, thereby avoiding the impact of the performance degradation of the AI ​​model on the positioning effect.

[0203] In some embodiments, the configuration information for the first positioning method and the configuration information for the second positioning method may be carried by the second information. For example, the configuration information for the first positioning method and the configuration information for the second positioning method may be included in two elements of the second information, respectively. The two elements of the second information may be, for example, two information fields of the second information.

[0204] In some embodiments, the configuration information for the first positioning method and the configuration information for the second positioning method may be sent by the second device at once. That is, the two units of the second information may be sent by the second device at once. Alternatively, the configuration information for the first positioning method and the configuration information for the second positioning method may be sent by the second device at two times. That is, the two units of the second information may be sent by the second device at two times.

[0205] In some embodiments, the second information and the first information may be the same or different. That is, the information indicating the use of the first positioning method and / or positioning method and the information representing the determination conditions for the first device to use the first positioning method for positioning may be the same information or different information.

[0206] In some embodiments, if the first device receives the first information, it may perform positioning based on the first information. For example, positioning may be performed based on the first positioning method and / or the second positioning method indicated by the first information. If the first device receives the second information, it may perform positioning based on the second information. For example, based on the determination condition indicated by the second information, it may determine whether to use the first positioning method or the second positioning method for positioning.

[0207] In some embodiments, the second information may be, for example, an LPP message, such as a request for location information (RequestLocationInformation).

[0208] In some embodiments, the name of the second information is not limited, and it can be, for example, "instruction information", "configuration information", etc.

[0209] Step S2203: The first device 101 performs positioning based on the second information.

[0210] In some embodiments, the first device 101 may perform positioning based on the second information.

[0211] In some embodiments, performing positioning based on the second information includes: performing positioning based on a first positioning method in response to a determination condition represented by the second information being met; and performing positioning based on a second positioning method in response to a determination condition represented by the second information not being met. Specific implementations may refer to the above embodiments and are not further described in this disclosure.

[0212] Step S2204 : The first device 101 sends third information to the second device 102 .

[0213] The optional implementation of step S2204 can refer to the optional implementation of step S2104 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0214] The positioning method involved in the embodiments of the present disclosure may include at least one of steps S2201 to S2204. Steps S2201 to S2204 can each be implemented as a separate embodiment. The embodiments can be combined in any manner and implemented in a different order, provided they are not in conflict. For example, step S2201 can be implemented as a standalone embodiment, but is not limited thereto.

[0215] In some embodiments, step S2202, step S2203, and step S2204 are optional, and one or more of these steps may be omitted or replaced in different embodiments.

[0216] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 b .

[0217] FIG2c is a schematic diagram illustrating an interaction of a positioning method according to an embodiment of the present disclosure. As shown in FIG2c , the present disclosure embodiment relates to a positioning method for a communication system 100, the method comprising:

[0218] In step S2301 , the second device 102 sends configuration information of a first positioning method and configuration information of a second positioning method to the first device 101 .

[0219] The optional implementation of step S2301 can refer to the optional implementation of step S2101 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0220] Step S2302: In response to not receiving the first information and the second information, the first device 101 performs positioning based on a preset rule.

[0221] In some embodiments, if the first device does not receive the first information and the second information, positioning can be performed based on preset rules. For example, positioning can be performed based on the first positioning method first, and then based on the second positioning method when the AI ​​model drops. Of course, this disclosure only refers to distance, and the preset rules can be set according to actual conditions, and this disclosure does not limit them.

[0222] Step S2303 : The first device 101 sends third information to the second device 102 .

[0223] The optional implementation of step S2303 can refer to the optional implementation of step S2104 in Figure 2a and other related parts in the embodiment involved in Figure 2a, which will not be repeated here.

[0332] In step S5101 , the second device 102 sends configuration information of a first positioning method and configuration information of a second positioning method to the first device 101 .

[0333] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the first device 101 and the second device 102, etc., which will not be repeated here.

[0335] In some embodiments, the above method may include the method of the above embodiments related to the communication system 100, the first device 101 and the second device 102, etc., which will not be repeated here.

[0336] In some embodiments, the present disclosure provides a positioning method configuration and control method, which is applied to a first device and sends a first message to a second device. For example, the first device may be an LMF and the second device may be a terminal. The first message includes a first unit that instructs the second device to perform positioning based on the first positioning method, i.e., a configuration for AI-based positioning. In addition, the first message also includes a second unit that further configures the second device to perform positioning based on a non-AI mode.

[0337] In some embodiments, the first message is the first information in the above embodiment.

[0338] In some embodiments, non-AI positioning methods may include DL-AoD, DL-TDOA, ECID, A-GNSS, etc. The information contained in the second unit includes configuration information for using these methods, including the following information:

[0339] RS configuration information, such as time-frequency resources and transmitted beam information;

[0340] Report result information, such as whether additional paths need to be reported, the granularity of reporting time information, whether LoS / NLoS information needs to be reported, whether power information needs to be reported, etc.

[0341] In some embodiments, the first unit and the second unit of the first message may be sent by the first device once or twice.

[0342] In some embodiments, the first message may further include indication information for instructing the terminal to select one of the positioning methods or use both positioning methods for positioning, and may further indicate which positioning method is the primary positioning method and which is the auxiliary positioning method.

[0343] In some embodiments, the first message may be an LPP message, such as a RequestLocationInformation message.

[0344] In some embodiments, the first message may further include a first determination threshold, where the first determination threshold is used to determine whether the first positioning method is used.

[0345] In some embodiments, the first determination threshold may be the determination condition in the above embodiment.

[0346] In some embodiments, positioning is performed for the second device based on the positioning method indicated by the first message.

[0347] In some embodiments, in response to the first message including information indicating which positioning method the terminal uses for positioning, the terminal selects one or two for positioning based on the indication, or the terminal determines whether to use the first positioning method based on the judgment threshold included in the first message.

[0348] In some embodiments, in response to the first message not including information indicating which positioning method the terminal uses for positioning, the terminal makes a selection based on a preset rule, for example, selecting only one or both positioning methods.

[0349] In some embodiments, the second device sends a second message to the first device, the second message including result information corresponding to the positioning method selected by the terminal, the result including corresponding indication information, and the first device can determine which positioning method the received result corresponds to based on the indication information.

[0350] In some embodiments, the second message is an LPP message, for example, a ProvideLocationInformation message.

[0351] For easier understanding, the present disclosure provides a specific embodiment as follows:

[0352] Step 1:

[0353] The network configures the terminal to use an AI-based positioning method and also configures the terminal to use a DL-TDOA-based method as a fallback method. At this point, the network can send a RequestLocationInformation message to the network. This message includes the configuration of the AI-based positioning method and the configuration of DL-TDOA. For DL-TDOA configuration information, see the attachment.

[0354] Alternatively, the first message further includes an instruction for the terminal to mainly use an AI-based method for positioning, and to use a DL-TDOA method only when the performance of the AI ​​positioning method deteriorates.

[0355] Or instruct the terminal to use both AI-based methods and DL-TDOA methods for positioning.

[0356] Alternatively, a first threshold is sent to the terminal, and when the first positioning method meets the first threshold, the first positioning method is used; otherwise, the DL-TDOA method is used for positioning.

[0357] Step 2: The terminal receives the first message from the LMF.

[0358] Step 3: The terminal performs positioning based on the instruction of the first message.

[0359] One implementation method is to use an AI-based positioning method or a DL-TDOA method for positioning based on the indication. Another implementation method is to use both an AI-based positioning method and a DL-TDOA method for positioning based on the indication information.

[0360] In one embodiment, a determination is made as to whether to use an AI-based positioning method based on a first determination threshold in the indication information. The first determination threshold may be, for example, the range of model input data, the terminal's channel status, etc. If the first determination threshold is met, the terminal uses the first positioning method for positioning; otherwise, the terminal uses the second positioning method for positioning.

[0361] Step 4: The terminal sends the result obtained by the positioning method to the LMF.
