Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a positioning model management method, a communication device, and a readable storage medium. Background Technology

[0002] With the rapid development of artificial intelligence (AI) and machine learning (ML) technologies, applying AI / ML to user equipment (UE) positioning and using pre-trained positioning models can achieve positioning accuracy that traditional methods cannot. For example, in severe non-line-of-sight (NLOS) situations, AI positioning can achieve positioning accuracy better than 1 meter, or even centimeter (cm), while traditional positioning methods cannot achieve an accuracy better than 1 meter.

[0003] However, using AI technology for positioning suffers from the problem of model generalization ability. That is, because the "environment / conditions" during training and inference differ, it's difficult to achieve the desired results when using positioning models trained in different "environments / conditions" interchangeably. Currently, the limited generalization ability of a single model is overcome by training positioning models separately for different "environments / conditions." However, with so many positioning models, there is currently a lack of feasible solutions for the network side to effectively manage the AI ​​positioning function of the UE, thereby improving positioning performance and optimizing network operating efficiency. Summary of the Invention

[0109] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c alone can mean: a alone, b alone, c alone, a combination of a and b, a combination of a and c, a combination of b and c, or a, b, and c, where a, b, and c can be single or multiple. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0110] Please see Figure 1 As shown, existing mobile communication systems include: location management function (LMF) 101 and TRP. Figure 1 The example uses three TRPs: TRP 102, TRP 103, and TRP 104. The LMF (Local Positioning Filter) is primarily responsible for selecting the positioning method and triggering corresponding positioning measurements, as well as calculating the positioning results and accuracy. The TRPs are mainly responsible for sending downlink Positioning Reference Signals (PRS) for positioning and receiving uplink Sounding Reference Signals (SRS) from the UE (UE 105). A base station can manage one or more TRPs. For example, in a 5G scenario, a single 5G base station (such as a next-generation gNB) can control multiple TRPs. The LMF and the base station can transmit positioning-related data based on the New Radio Positioning Protocol (NRPPa), while the UE and the LMF can transmit positioning-related data based on the LTE Positioning Protocol (LPP).

[0111] use Figure 1 When the mobile communication system shown implements UE positioning, it can use downlink PRS for UE positioning. The positioning process and principle are as follows:

[0112] One positioning method is as follows: LMF101 configures TRP 102, TRP 103 and TRP 104 to send PRS, and UE 105 calculates the UE 105 positioning result based on the time relationship between the three received PRS and the location information of each TRP.

[0113] Another positioning method is as follows: the UE sends the temporal relationship between the three received PRS to the network-side device, which then calculates the UE's positioning result. For example, Figure 1 In the embodiment shown, the UE sends the temporal relationship between the three PRS received above to the LMF 101, and the LMF 101 calculates the UE positioning result based on the temporal relationship between the three PRS and the location information of each TRP.

[0114] When AI / ML technology is introduced for localization, a pre-trained localization model can be used. Figure 2A and Figure 2B The implementation methods of direct positioning and indirect positioning are shown respectively.

[0115] Please see Figure 2A As shown, direct positioning refers to using channel measurement information of M positioning reference signals as input to the model during training, and the UE positioning result as the model output, thus obtaining the positioning model through training. During inference (running), the trained positioning model is deployed on the UE or network side. Then, using the channel measurement information of the M positioning reference signals as input to the positioning model, the positioning model outputs the predicted UE location.

[0116] Please see Figure 2B As shown, indirect positioning refers to a positioning model that uses channel measurement information of M positioning reference signals as input, outputs intermediate values, and uses these intermediate values ​​to further calculate the UE positioning result.

[0117] Model generalization ability represents a model's predictive ability on new, unseen data. Stronger generalization ability corresponds to stronger predictive ability, and vice versa. In localization scenarios, the problem with model generalization ability mainly stems from the incompatibility of the "environment / conditions" between training and inference. This leads to significant discrepancies between the input data used in training and inference, causing the model to fail to achieve the expected results during inference (the predictive performance during training).

[0118] For example, in an industrial setting, localization model 1 is trained in factory 1 environment, and localization model 2 is trained in factory 2 environment.

[0119] Because factory 1 and factory 2 differ in their layout, the number and location of TRPs used for positioning services, the configuration of TRP positioning reference signals, and the wireless signal reflection environment, positioning model 1 trained in factory 1 achieves better prediction results when used in factory 1 than in factory 2. Similarly, positioning model 2 trained in factory 2 achieves better prediction results when used in factory 2 than in factory 1. Furthermore, changes in the environment of factory 1 or factory 2 can cause the positioning accuracy during inference to fall short of the accuracy achieved during training. These issues are due to the limited generalization ability of the models.

[0120] To address the limited generalization ability of models and achieve accurate localization in the UE, a large number of different, pre-trained localization models need to be deployed in the UE to cope with different "environments / conditions". Then, a matching localization model is selected for inference based on the "environment / conditions" that are about to / are in progress, so that the "environment / conditions" during the training and inference of the selected localization model are consistent. In this way, the selected localization model can achieve better performance during inference.

[0121] Faced with so many positioning models, there is currently no feasible solution for network-side devices to effectively manage the AI ​​positioning function of UE, thereby improving positioning performance and optimizing network operation efficiency.

[0122] Based on this, this application provides a positioning model management method, communication device, and readable storage medium. The method involves a network-side device sending information about the positioning environment or conditions instructing the UE to perform positioning. This assists the UE in determining the most suitable candidate positioning model to operate under the specified "positioning environment or conditions," and then reporting the mapping information of the candidate positioning models to the network-side device. In this way, the network-side device can effectively manage the UE's AI positioning function. When configuring the AI ​​positioning function of the UE or base station, the mapping information of the candidate positioning models can be used as a configuration basis, thereby improving positioning performance and optimizing network operating efficiency.

[0123] In this application, the UE can be any device that needs to use location services in any scenario. The type of UE is not limited; for example, the UE can be a device with location requirements in an industrial scenario, a monitoring device with location requirements in a monitoring scenario, etc. Network-side devices can be, but are not limited to, LMFs, base stations, etc.

[0124] The positioning model management method provided in this disclosure will be described in detail below through some specific embodiments.

[0125] Figure 3 A flowchart illustrating a positioning model management method provided in one embodiment of this application. Please refer to [link / reference]. Figure 3 As shown, the method in this embodiment includes:

[0126] S301. The network-side device sends first information to the UE. The first information is used to indicate the positioning environment or positioning conditions for the UE to perform positioning. The first information is used to assist the UE in determining the candidate positioning model for positioning.

[0127] In this embodiment, UE positioning refers to UE using AI technology for positioning (hereinafter referred to as AI positioning). Here, UE positioning can mean that the UE is currently performing positioning or that the UE is about to perform positioning; this application does not limit this.

[0128] The location environment indicates the environment of the geographical area that supports AI positioning for the UE, or the environment of the geographical area where the UE is currently located. The range of the geographical area that supports AI positioning for the UE can be determined based on the UE's current location. For example, the geographical area that supports AI positioning for the UE can be a range centered on the UE's current location with a preset distance as its radius.

[0129] Location conditions indicate the specific conditions, constraints, or requirements required for the UE to perform location. For example, location conditions may specify conditions that the bit model needs to meet, or location conditions may refer to the conditions that the location environment for the UE to perform AI location needs to meet.

[0130] Network-side devices can determine the positioning environment / conditions for UE positioning in any way, and this application does not limit this. For example, network-side devices can determine the positioning environment / conditions for UE positioning based on changes in UE location, UE device type, and the wireless environment of the UE's location.

[0131] The first information can be understood as network-side positioning assistance information, which is used to help the UE select the most suitable positioning model to operate under the positioning environment or positioning conditions indicated by the network-side device.

[0132] S302. The UE determines a candidate positioning model for positioning based on the first information. The environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0133] In some embodiments, the UE may pre-store the environment or conditions of the positioning model supported by the UE during training. After receiving the first information, the UE can obtain the positioning environment or conditions indicated by the network-side device from the first information. Based on the positioning environment or conditions indicated by the network-side device and the training environment or conditions of the positioning model supported by the UE, the UE determines the most suitable candidate positioning model for operation.

[0134] Among them, the environment or conditions during the training of the candidate localization model meet the preset requirements of the localization environment or conditions indicated by the first information. This can be understood as the localization model being consistent with or having a similarity to the localization environment or conditions indicated by the first information during training. In this way, the problem of limiting the generalization ability of the model can be overcome as much as possible.

[0135] Candidate localization models can be located locally on the UE (i.e., already downloaded to the UE), or they can be downloaded to the UE from the network side / third-party server via some communication method. If the UE selects a candidate localization model for deployment inference, the candidate localization model can perform UE localization functions based on AI technology.

[0136] Among them, the candidate positioning models determined by the UE for positioning can form a candidate positioning model set, which includes one or more candidate positioning models.

[0137] S303. The UE sends second information to the network-side device. The second information includes mapping information of candidate positioning models. The mapping information is used to indicate the candidate configuration that the UE prefers for positioning, or the positioning model that the UE prefers for positioning, or the positioning capability that the UE supports.

[0138] The UE maps each candidate positioning model in the candidate positioning model set to obtain mapping information corresponding to each candidate positioning model. The mapping information of one candidate positioning model represents a UE preference. It should be noted that there may be cases where the mapping information of some candidate positioning models is not sent to the UE. That is, the second information may include the mapping information corresponding to all candidate positioning models, i.e., the preferences of all UEs, or it may include the mapping information corresponding to some candidate positioning models, i.e., the preferences of some UEs. This application does not limit this.

[0139] This application does not limit the mapping method. For example, the relationship between the positioning model and the parameter configuration item can be used to map and obtain the candidate configuration that the UE prefers for positioning. Alternatively, all or part of the candidate positioning models in the candidate positioning model set can be directly determined as the positioning model that the UE prefers for positioning. Alternatively, the relationship between the positioning model and the positioning capability (AI positioning capability) can be used to map and obtain the positioning capability (AI positioning capability) that the UE is suitable to use in the positioning environment or positioning conditions indicated by the network-side device.

[0140] In this context, the candidate configurations that the UE prefers for positioning can be understood as configurations that the UE suggests to the network side, or configurations that the UE prefers to select. It should be understood that the candidate configurations that the UE prefers can be network-side configurations, UE-side configurations, or both network-side and UE-side configurations. This application does not limit this. Similarly, the positioning model that the UE prefers for positioning can be understood as a positioning model that the UE suggests to the network side, or a positioning model that the UE prefers to select. Similarly, the AI ​​positioning capabilities supported by the UE indicated by the mapping information can be understood as the AI ​​positioning capabilities that the UE can use and are most suitable for use in the positioning environment or positioning conditions indicated by the network-side device.

[0141] The UE reports its preferred candidate configuration, preferred positioning model, or AI positioning capability to the network-side device by sending a second piece of information, namely, the mapping information of the candidate positioning model.

[0142] In this embodiment, the network-side device sends a positioning environment or positioning conditions to the UE, instructing the UE to perform positioning. This assists the UE in determining the positioning model that operates under the positioning environment or positioning conditions indicated by the network-side device. Then, the UE reports the mapping information of the candidate positioning models as the UE's preference to the network-side device. In this way, the network-side device can effectively manage the UE's AI positioning function. When configuring the AI ​​positioning function of the UE or the base station, the UE's preference can be used as the basis for the network-side device to configure the positioning function of the UE and the positioning function of the base station. By taking the UE's preference into account, the network-side device can optimize network operating efficiency and the UE, and improve the UE's positioning performance.

[0143] Next, we will introduce in detail how the network-side device sends the first information to the UE, from the aspects of the content of the first information and the transmission method of the first information.

[0144] The first information includes the following:

[0145] The first piece of information may include one or more of the following:

[0146] Identification information (also called cell identification information) of one or more cells that support providing location services to the UE. Cell identification information indicates which cells within a geographic area can provide AI location services to the UE, or whether the cell the UE is currently in can provide AI location services to the UE. Identification information can take the form of a global cell identifier (GCI). When there are multiple cells that support providing location services to the UE, the cell identification information can be in the form of a cell identifier list.

[0147] The system supports the identification information of geographical areas that provide location services to the UE. The identification information of geographical areas can be related identifiers of geographical areas or related identifiers of location scenarios within geographical areas. For example, it can be a globally unique location identifier or scenario identifier (such as the ID of factory 1) pre-negotiated between the UE and the network-side equipment, or the geographical coordinate area of ​​a factory that supports the location function. The geographical coordinate area can be represented by absolute coordinates (such as WGS-84) or relative coordinates.

[0148] Supports time synchronization between TRPs in the cell providing location services to the UE. For example, the synchronization error between TRPs can be a time value, such as 10ns or 20ns, or a time range or magnitude, such as 0-10ns, 0-20ns, 0-50ns, or 10-100ns.

[0149] This supports time synchronization between base stations or between TRPs within a geographical area that provides location services to the UE. For example, the synchronization error between base stations or between TRPs within a geographical area can be a time value, such as 10ns or 20ns, or a time magnitude or range, such as 0-10ns, 0-20ns, 0-50ns, or 10-100ns. A single base station can maintain multiple TRPs, and multiple TRPs belonging to the same base station can be considered to have no time error.

[0150] The time synchronization status between the UE and the base station, and / or the time synchronization status between the UE and the TRP, can be a time value, a time range, or a time order of magnitude.

[0151] It supports providing wireless environment information in the cell or geographical area to the UE, such as SNR and SINR, which can be a certain level or range, such as -10-10dB, 10-20dB, 20-50dB, etc.

[0152] It supports providing TRP information in the cell or geographic area to the UE for location services, such as the number of TRPs, TRP number information, and TRP location information. The TRP location information can be represented using absolute coordinates (such as WGS-84) or relative coordinates.

[0153] The configuration information of positioning reference signal resources that can be used for positioning in the cell or geographical area that supports providing positioning services to the UE, wherein the positioning reference signal resources are PRS resources or SRS resources.

[0154] The configuration information of the location reference signal resource set that can be used for positioning in the cell or geographical area that supports providing positioning services to the UE, wherein the location reference signal resource set is a PRS resource set or an SRS resource set.

[0155] The above information can indicate the positioning environment or conditions for the UE to perform positioning, thus helping the UE select the most suitable positioning model.

[0156] The method of transmitting first information:

[0157] Network-side devices can send the first information to the UE based on LPP or RRC signaling or system messages.

[0158] Transmission method 1: The network-side device sends the first information to the UE based on LPP.

[0159] Among them, LPP is a protocol used for location positioning technology in LTE networks. It defines the process and message exchange method for measuring and locating device positions in LTE networks. (This is in conjunction with the preceding text.) Figure 1 The UE and LMF can transmit positioning-related data based on the LPP protocol. Generally, the interaction of positioning data between the UE and LMF includes three stages: 1. Positioning capability transmission; 2. Positioning auxiliary data transmission; 3. Location information transmission, wherein the location information includes measurement information and / or location estimation information.

[0160] This application can send first information to the UE using downlink messages during the positioning-assisted data transmission phase. Combined with... Figure 3 As shown, S301 can be accessed via Figure 4 The illustrated embodiment is implemented as shown. Please refer to [link / reference]. Figure 4 As shown, it may include:

[0161] S401. The network-side device sends a location assistance data element (IE) to the UE based on LPP. The location assistance data element carries first information. Correspondingly, the UE receives the location assistance data element.

[0162] In this embodiment, the first information is included in LPP-based positioning assistance data elements, and the UE can obtain the first information from the received positioning assistance data elements. Alternatively, it can be understood that the network-side device sends the first information to the UE via unicast.

[0163] When sending the first information to the UE using transmission mode 1, the network-side device is the LMF in the core network device. Furthermore, using transmission mode 1 only requires extending the existing message format without modifying the existing protocol, thus achieving information reporting without altering the entire existing protocol, demonstrating strong scalability.

[0164] S402. The UE determines a candidate positioning model for positioning based on the first information. The environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0165] S403. The UE sends second information to the network-side device. The second information includes mapping information of the candidate positioning model set. The mapping information is used to indicate the candidate configuration that the UE prefers for positioning, or the positioning model that the UE prefers for positioning, or the positioning capability that the UE supports.

[0166] In this embodiment, S402, S403 and Figure 3 The embodiments S302 and S303 shown are similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0167] It should be noted that, based on the LPP definition of the process and message exchange method for device location measurement and positioning in the LTE network, the network-side device can provide assistance data upon request from the UE. Therefore, before the network-side device sends location assistance data elements to the UE, the UE can also send a request for assistance data to the network-side device, such as... Figure 4 The location assistance data request is shown in the dashed box.

[0168] Furthermore, LPP defines the general process by which the UE and LMF can transmit location-related data based on the LPP protocol. It should be understood that the transmission of location capability information generally occurs before the transmission of location auxiliary data, such as... Figure 4 The positioning capability information transmission shown in the dashed box occurs before the transmission of positioning auxiliary data.

[0169] Transmission Method 2: The network-side device sends the first information to the UE based on RRC signaling.

[0170] RRC signaling is a lightweight control signaling system used to manage radio resources and connection status in a radio access network. RRC signaling is mainly used for communication between the UE and the base station.

[0171] Combination Figure 3 As shown, S301 can be accessed via Figure 5 The illustrated embodiment is implemented as shown. Please refer to [link / reference]. Figure 5 As shown, the method in this embodiment includes:

[0172] S501. The network-side device sends a first RRC signaling message to the UE, and the first RRC signaling message carries first information.

[0173] The first information can be included as an information element (IE) in the UE-specific RRC signaling, i.e., the first RRC signaling, which is sent by the base station to the UE. The UE can obtain the first information from the first RRC signaling.

[0174] In some cases, the base station can proactively send the first RRC signaling to the UE.

[0175] In other cases, the base station can send the first RRC signaling to the UE based on the triggering of a network entity in the core network. For example, the LMF may send the first information to the base station based on the NPRRa protocol, thereby triggering the base station to send the first information to the UE via the first RRC signaling. It should be understood that this is not limited to the LMF sending the first information to the base station; it can also be other network entities in the core network.

[0176] The base station may unicast the first RRC signaling or broadcast the first RRC signaling; this application does not limit this.

[0177] S502, the UE determines a candidate positioning model for positioning based on the first information, and the environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0178] S503, the UE sends second information to the network-side device. The second information includes mapping information of the candidate positioning model set. The mapping information is used to instruct the UE to select candidate configuration items related to positioning or to select available positioning models related to positioning or positioning capabilities supported by the UE.

[0179] In this embodiment, S502, S503 and Figure 3 The embodiments S302 and S303 shown are similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0180] The method in this embodiment sends first information to the UE via RRC signaling. Since RRC signaling is a lightweight control signaling, the transmission speed is faster, thereby saving transmission time.

[0181] Transmission method 3: The network-side device sends the first information to the UE based on system messages.

[0182] System messages are usually broadcast to UEs within the coverage area, and the UEs receive, parse, and process them.

[0183] Combination Figure 3 As shown, S301 can be accessed via Figure 6 The illustrated embodiment is implemented as shown. Please refer to [link / reference]. Figure 6 As shown, the method in this embodiment includes:

[0184] S601. The network-side device sends a system message to the UE, the system message carrying first information. Accordingly, the UE receives the system message and can obtain the first information from the system message.

[0185] In some embodiments, the system message includes an SIB, which can be an existing SIB in the protocol or a newly added SIB. The existing SIB in the protocol can be a posSIB or not (hereinafter referred to as SIBx), such as SIB2, SIB3, SIB4, SIB5, etc. It should be noted that SIB1 differs from other SIBs. Generally, SIB1 is not used to transmit the first information; instead, the first information is added to an SIB other than SIB1. However, in specific circumstances, SIB1 can also be used to transmit the first information. Therefore, whether to use SIB1 to transmit the first information can be determined based on the actual situation.

[0186] Here, posSIB is a system information block used to transmit location-related data. In this application, posSIB can be a cell-specific posSIB or a region-specific posSIB. Based on this, when the base station transmits the first information by broadcasting, it can use a cell-specific posSIB to broadcast within a single cell, or it can use a region-specific posSIB to broadcast within a geographical area containing one or more cells.

[0187] The posSIB type can be an existing posSIB type in the protocol or a custom posSIB type. Table 1 provides examples of posSIB types defined in the protocol.

[0188] Table 1

[0189]

[0190] Table 1 above exemplifies the posSIB types corresponding to the transmission of five different location-related data as defined in the protocol. Based on Table 1, this application can use any of the posSIB types shown in Table 1 to carry the first information, or it can add custom posSIB types based on Table 1, such as posSIB type 7-x, where x is used to distinguish different custom posSIB types, and x can be a number.

[0191] S602, The UE determines a candidate positioning model for positioning based on the first information. The environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0192] S603, the UE sends second information to the network-side device. The second information includes mapping information of the candidate positioning model set. The mapping information is used to indicate the candidate configuration that the UE prefers for positioning, or the positioning model that the UE prefers for positioning, or the positioning capability that the UE supports.

[0193] In this embodiment, S602, S603 and Figure 3 The embodiments S302 and S303 shown are similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0194] This embodiment enables the sending of first information to the UE using system messages.

[0195] When sending the first information to the UE using transmission mode 3, the following methods can also be used: Figure 7 Implemented as shown:

[0196] S701, The network-side device encrypts the first information to obtain the first ciphertext.

[0197] In some embodiments, the first information broadcast by the network-side device within a cell or a geographical area can be encrypted using block encryption. Block encryption refers to pre-grouping the UE into blocks, and then encrypting them according to the encryption method (or encryption algorithm) of the block to which the UE belongs, as well as the encryption key, to obtain the first ciphertext.

[0198] The criteria for grouping UEs may include, but are not limited to, one or more of the following: UE type, UE priority, UE positioning accuracy requirements, and positioning method complexity. The network-side equipment and the UE pre-agree on the encryption and decryption methods. Based on the different UE groups, the network-side equipment pre-assigns encryption and decryption keys to each group of UEs and notifies the UE of the decryption key to ensure that the UE can correctly decrypt and obtain the initial information.

[0199] S702, The network-side device sends a system message to the UE, and the system message carries the first ciphertext.

[0200] The network-side device can add the first ciphertext to the SIB contained in the system message and broadcast it in a cell or a geographical area. The UE receives the broadcast system message and can decrypt the first ciphertext carried in the SIB based on the pre-allocated decryption key and the pre-agreed decryption method to obtain the first information.

[0201] S703, the UE decrypts the first ciphertext to obtain the first information, and determines a candidate positioning model for positioning based on the first information. The environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0202] The UE decrypts the first ciphertext in the SIB based on the decryption key notified by the network-side device to obtain the first information.

[0203] S704. The UE sends second information to the network-side device. The second information includes mapping information of the candidate positioning model set. The mapping information is used to indicate the candidate configuration that the UE prefers for positioning, or the positioning model that the UE prefers for positioning, or the positioning capability that the UE supports.

[0204] In this embodiment, S703, S704 and Figure 3 The embodiments S302 and S303 shown are similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0205] The method in this embodiment encrypts the first information. UEs within the same group as the UE can successfully decrypt it, while UEs outside the same group cannot successfully decrypt it and therefore cannot obtain the first information. This improves the security of the first information.

[0206] Next, we will introduce in detail the implementation method of the UE sending the second information to the network-side device from the aspects of the form of the second information and the transmission method of the second information.

[0207] The second piece of information can be understood as the UE preference, used to indicate the configuration recommended by the UE, or to indicate the AI ​​positioning capabilities available to the UE in the positioning environment or positioning device indicated by the network-side device, or to indicate the positioning model recommended by the UE.

[0208] The form of the second message:

[0209] The newly defined first information element carries the second information, that is, the first information element represents one or more UE preferences. The first information element is, for example, POSITIONING-AI-Preferences.

[0210] Second information transmission method:

[0211] The UE sends second information to the network-side device. The second information can be reported together with the UE's capabilities, or they can be reported separately.

[0212] Transmission method 1: The second information is transmitted using the uplink message of LPP, which carries the UE's positioning capability report.

[0213] Please see Figure 8 As shown, the method in this embodiment includes:

[0214] S801. The network-side device sends first information to the UE. The first information is used to indicate the positioning environment or positioning conditions for the UE to perform positioning. The first information is used to assist the UE in determining the candidate positioning model for positioning.

[0215] In this embodiment, S801 and Figure 3 In the illustrated embodiment, S301 is similar. Combined with the foregoing description, it can be achieved as shown above. Figures 4 to 7 The implementation shown in any embodiment will not be described in detail here for the sake of simplicity.

[0216] S802, the UE determines a candidate positioning model for positioning based on the first information, and the environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0217] In this embodiment, S802 and Figure 3 The embodiment S302 shown is similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0218] Figure 3 The S303 of the illustrated embodiment can be implemented by the S803 of this embodiment.

[0219] S803, the UE sends an LPP-based uplink message to the network-side device. The LPP-based uplink message carries the UE's positioning capability report, and the positioning capability report carries a first information element used to carry the second information.

[0220] Correspondingly, the network-side equipment receives uplink messages based on LPP.

[0221] In this embodiment, the uplink message based on LPP can be understood as a positioning capability report message, which carries a positioning capability report formed based on the positioning capabilities supported by the UE. The second information is embedded in the UE's positioning capability report and sent to the network-side device as part of the UE's positioning capability report. The meaning and content of the second information are consistent with the previous description and will not be repeated here for the sake of brevity.

[0222] The UE can add the first information element carrying the second information to any or a specified location in the UE's positioning capability report, so that the network-side device can parse the second information. This application does not limit this.

[0223] For example, the first information element can be added as an outer information element in the UE's positioning capability report, or it can be added as an inner information element within any information element in the UE's positioning capability report. This application does not limit this.

[0224] For example, Figure 9AThis example illustrates a scenario where the first information cell is added as an outer information cell to the UE's positioning capability report. Figure 9A In the illustrated embodiment, the UE supports E-CID-based capabilities, Multi-RTT-based capabilities, OTDOA-based capabilities, and DL-TDOA-based capabilities. The first information element is appended after the four positioning capabilities. That is, the first information element can, but is not limited to, be appended to the end of the UE's positioning capability report. Combined with... Figure 9A As shown, the first information element and the information element carrying the location capability information supported by the UE belong to the same layer, and are the first layer information elements of the UE's location capability report, i.e., the outer layer information elements.

[0225] Figure 9B This example illustrates a scenario where the first information cell is added as an inner information cell to the UE's positioning capability report. Figure 9B In the illustrated embodiment, the UE supports E-CID-based capabilities, Multi-RTT-based capabilities, OTDOA-based capabilities, and DL-TDOA-based capabilities, with the first information cell added to any of these positioning capabilities. For example, Figure 9B In the illustrated embodiment, the first information element is added inside the information element carrying information related to DL-TDOA-based capabilities. That is, the first information element is an inner layer information element of the information element carrying information related to the positioning capabilities supported by the UE.

[0226] In some embodiments, the second information is embedded in the UE's positioning capability report. This second information may include parameter configuration information for one or more target positioning capabilities. The target positioning capability is an AI-based positioning capability determined based on candidate positioning model mapping. It should be understood that the parameter configuration information of the target positioning capability can be used to indicate the candidate configuration preferred by the UE, the positioning model preferred by the UE (the positioning model corresponding to the target positioning capability), or the AI ​​positioning capability suitable for the UE to use in the positioning environment or conditions indicated by the network-side device.

[0227] The AI ​​positioning capabilities supported by the UE may include, but are not limited to, the following: capabilities based on Enhanced Cell-ID (E-CID), Observed Time Difference of Arrival (OTDOA), New Radio Enhanced Cell-ID (NR-ECID), Multi-Round-Trip Time (Multi-RTT), Downlink Angle of Departure (DL-AOD), Downlink Time Different Of Arrival (DL-TDOA), Uplink Angle of Arrival (UL-AOA), and Uplink-time Different Of Arrival (UL-TDOA). Target positioning capability may be one of the aforementioned AI positioning capabilities supported by the UE.

[0228] Furthermore, the first information element may include one or more second information elements, each second information element carrying parameter configuration information for a target positioning capability. The information format of the target positioning capability parameter configuration information can be either a first information format or a second information format. The first information format is the format corresponding to the parameter configuration information of the positioning capability in the LPP-based positioning capability report, while the second information format is a different format from the first information format. The second information format can be a custom information format or the information format of the parameter configuration information for AI positioning capabilities.

[0229] That is, the parameter configuration information of the target positioning capability can reuse the format or form of the parameter configuration information of other positioning capabilities in the UE's positioning capability report, or it can not reuse it and use a custom information format or the information format of the parameter configuration information of the AI ​​positioning capability.

[0230] By using transmission method 1, the second information can be embedded in the UE's positioning capability report and sent to the network-side device, reducing the number of interactions between the UE and the network-side device and improving communication efficiency.

[0231] Transmission Method 2: The second information is transmitted using the uplink message of LPP. The uplink message does not carry the UE's positioning capability report.

[0232] Please see Figure 10 As shown, the method in this embodiment includes:

[0233] S1001, The network-side device sends first information to the UE. The first information is used to indicate the positioning environment or positioning conditions for the UE to perform positioning. The first information is used to assist the UE in determining the candidate positioning model for positioning.

[0234] In this embodiment, S1001 and Figure 3 In the illustrated embodiment, S301 is similar. Combined with the foregoing description, it can be achieved as shown above. Figures 4 to 7 The implementation shown in any embodiment will not be described in detail here for the sake of simplicity.

[0235] S1002, The UE determines a candidate positioning model for positioning based on the first information. The environment or conditions during the training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0236] In this embodiment, S1002 and Figure 3 The embodiment S302 shown is similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0237] Figure 3 The S303 of the illustrated embodiment can be implemented by the S1003 of this embodiment.

[0238] S1003, the UE sends an uplink message based on LPP to the network-side device. The uplink message based on LPP carries a first information element for carrying second information, and the uplink message based on LPP does not carry the UE's positioning capability report.

[0239] Correspondingly, the network-side equipment receives uplink messages based on LPP.

[0240] In this embodiment, the UE sends its positioning capability report and second information separately. The meaning and content of the second information are the same as described above and will not be repeated here for the sake of brevity.

[0241] In some embodiments, the uplink message based on LPP can be an existing uplink message that transmits location capability-related information based on LPP, and the existing uplink message does not carry a location capability report.

[0242] In other embodiments, the LPP-based uplink message is a new uplink message in the process of transmitting positioning capability-related information based on LPP.

[0243] In other embodiments, the current LPP-based transmission of positioning-related data includes: a positioning capability information transmission process, a positioning auxiliary data transmission process, and a location information transmission process. Based on this, a UE preference transmission process can be added, and the uplink message based on LPP can be the uplink message in the added UE preference transmission process. The UE preference transmission process can be executed before, after, or in parallel with the positioning auxiliary data transmission process.

[0244] The information format of the first information cell, including its contents and the parameter configuration information for target localization capability, can be found in [reference needed]. Figure 8 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0245] Transmission method 3: Transmit the second information using RRC signaling.

[0246] Please see Figure 11 As shown, the method in this embodiment includes:

[0247] S1101. The network-side device sends first information to the UE. The first information is used to indicate the positioning environment or positioning conditions for the UE to perform positioning. The first information is used to assist the UE in determining the candidate positioning model for positioning.

[0248] In this embodiment, S1101 and Figure 3 In the illustrated embodiment, S301 is similar. Combined with the foregoing description, it can be achieved as shown above. Figures 4 to 7 The implementation shown in any embodiment will not be described in detail here for the sake of simplicity.

[0249] S1102. The UE determines a candidate positioning model for positioning based on the first information. The environment or conditions during training of the candidate positioning model meet the preset requirements of the positioning environment or conditions indicated by the first information.

[0250] In this embodiment, S1102 and Figure 3 The embodiment S302 shown is similar and can be referred to. Figure 3 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0251] Figure 3 The S303 of the illustrated embodiment can be implemented by the S1103 of this embodiment.

[0252] S1103, the UE sends a second RRC signaling message to the network-side device, the second RRC signaling message carrying a first information element used to carry second information. Correspondingly, the network-side device receives the second RRC signaling message.

[0253] That is, the first information element is included in the second RRC signaling and sent by the UE to the base station. The base station can obtain the second information from the second RRC signaling. The meaning and content of the second information are the same as those described above, and will not be repeated here for the sake of brevity.

[0254] The information format of the content contained in the first information cell and the parameter configuration information of the target positioning capability in the first information cell can be referred to as follows. Figure 8 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0255] The method in this embodiment sends the second information to the base station via RRC signaling. Since RRC signaling is a lightweight control signaling, it has a fast transmission speed, thereby saving transmission time.

[0256] The UE can also send information indicating the positioning model to the network-side device so that the network-side device can accurately determine the positioning model recommended by the UE.

[0257] exist Figures 8 to 11 Based on any embodiment, the first information cell may further include a third information cell. The third information cell carries information indicating the candidate positioning model.

[0258] The information indicating the candidate positioning model may include one or more of the following: the identifier of the positioning method, the identifier of the positioning model, the expected positioning performance of the positioning method, the expected positioning performance of the positioning model, the monitoring methods supported by the positioning method, the monitoring methods supported by the positioning model, the complexity information of the positioning method, the complexity information of the positioning model, the base station information associated with the candidate positioning model, the Transmitter / Receiver Point (TRP) information associated with the candidate positioning model, the positioning reference signal resource configuration information associated with the candidate positioning model for positioning, and the positioning reference signal resource set configuration information associated with the candidate positioning model for positioning.

[0259] The identifier of the positioning method may include, but is not limited to, the name of the positioning method and the positioning method ID. Accordingly, the network-side device can determine the positioning method supported by the UE based on the positioning method identifier indicated by the UE, and then determine that the positioning model used by the positioning method is the candidate positioning model suggested by the UE.

[0260] The identifiers of one or more positioning models supported by the UE may include, but are not limited to, the name of the positioning model and the positioning model ID. Accordingly, the network-side device can directly determine which candidate positioning models the UE recommends based on the identifiers of the positioning models.

[0261] The expected positioning performance includes one or more of the following: the area range supporting positioning, the supported positioning accuracy, the QoS indicators or QoS capabilities of the supported positioning services, and the period or delay characteristics of UE positioning information reporting supported by the model. For example, the area range supporting positioning can be a geographical area that can guarantee a certain positioning accuracy, which can be represented by latitude and longitude, altitude, etc.; the positioning accuracy can be the expected positioning accuracy of the model in a specific situation, a certain area, or a certain cell, such as a positioning accuracy better than 1 meter, 0.5 meters, etc.; the QoS indicators or QoS capabilities of the positioning services can be error predictions based on the model output; the period or delay characteristics of UE positioning information reporting supported by the model refer to the period options, period intervals, or period ranges for the model to report measurement values ​​related to the model output, as well as the expected delay value or delay range for reporting measurement values, such as a delay value of 500ms, 1s, etc. Accordingly, based on the UE's indication, the network-side equipment determines which positioning methods meet the expected positioning performance, and then determines the positioning models used by these positioning methods that meet the expected positioning performance as candidate positioning models recommended by the UE.

[0262] The location method supports monitoring methods that may include, but are not limited to, one or more of the following: support for UE-side monitoring / support for network-side device monitoring, supported monitoring objects, and supported monitoring report reporting cycles (e.g., reporting once every 500ms). The monitoring objects may include one or more of the following: input data of the location model (e.g., monitoring CIR), and output data of the location model (e.g., monitoring the UE's location information output by the location model or monitoring the intermediate results output by the location model). Accordingly, based on the UE's indication, the network-side device determines which location methods satisfy the monitoring method indicated by the first information, and then determines the location model used by these location methods that satisfy the monitoring method as the candidate location model suggested by the UE.

[0263] The monitoring methods supported by the positioning model may include, but are not limited to, one or more of the following: supporting UE-side monitoring / supporting network-side device monitoring, supported monitoring objects, and supported monitoring report reporting cycle (e.g., reporting once every 500ms). The monitoring objects may include one or more of the following: input data of the positioning model (e.g., monitoring CIR), and output data of the positioning model (e.g., monitoring the UE's location information output by the positioning model). Accordingly, based on the UE's indication, the network-side device determines which positioning models whose monitoring methods satisfy the first information indication include, and then determines these positioning models that satisfy the monitoring methods as candidate positioning models suggested by the UE.

[0264] The complexity information of the positioning method may include, but is not limited to, the number of parameters involved in the positioning method. Accordingly, based on the UE's indication, the network-side device determines which positioning methods have complexity information that satisfies the first information indication, and then determines the positioning model used by these positioning methods that meet the complexity requirements as the candidate positioning model suggested by the UE.

[0265] The complexity information of the positioning model may include, but is not limited to, the number of model parameters of the positioning model. Accordingly, based on the UE's indication, the network-side device determines which positioning models have complexity information that satisfies the first information indication, and then determines these positioning models that satisfy the positioning model as candidate positioning models recommended by the UE.

[0266] The location model-related TRP information may include, but is not limited to, one or more of the following: TRP quantity, TRP number information, TRP location information, and TRP description information. The TRP location information can be the absolute coordinates (e.g., WGS-84) or relative coordinates of the TRP; the TRP number information can be a number associated with the TRP location information and coordinates. Accordingly, based on the UE's instructions, the network-side device determines which location models match the TRP information, and then identifies these matching location models as candidate location models suggested by the UE.

[0267] The base station information related to the positioning model can include information about one or more base stations within one or more geographical areas, such as the base station identifier (e.g., gNB ID) of each base station and the TRP group information under that base station. Within a geographical area, multiple TRPs can form a TRP group, and a TRP group typically belongs to one base station. Therefore, the TRP information under a base station refers to the TRP group information under that base station, such as the TRP group identifier, description information of each TRP in the TRP group, etc. In some cases, the TRP group information under a base station can be transmitted using a default method. The network-side device assumes that all TRP groups under that base station are TRPs associated with the positioning model supported by the UE. Accordingly, based on the UE's instructions, the network-side device determines the corresponding base station based on the base station identifier, determines the TRPs associated with the positioning model based on the TRP group information under the base station, matches the positioning model based on the TRPs associated with the positioning model, and determines the matching positioning model as the candidate positioning model suggested by the UE.

[0268] The positioning reference signal resource configuration information associated with the positioning model, such as PRS resources or SRS resources. Based on the UE's indication, the network-side device determines the positioning model that supports the PRS or SRS resources indicated by the UE as the candidate positioning model suggested by the UE.

[0269] Configuration information for the location reference signal resource set associated with the location model, such as the PRS resource set or SRS resource set. Based on the UE's indication, the network-side device determines the location model that supports the PRS resource set or SRS resource set indicated by the UE as the candidate location model suggested by the UE.

[0270] This application does not limit the position of the third information cell within the first information cell. For example, the third information cell can be added to the first information cell and parallel to the second information cell; or, the third information cell can be added inside any second information cell. The UE and the network-side device need to reach an agreement in advance so that the network-side device can parse the information carried in the third information cell from the correct position.

[0271] Combination Figures 3 to 11 In the embodiment shown, the network-side device can proactively send the first information to the UE, that is, the timing of sending the first information to the UE is determined by the network-side device.

[0272] In addition, network-side devices can also send initial information to the UE upon request. The UE can use different methods to send requests to the network-side devices in different scenarios. The following sections will describe several scenarios in detail.

[0273] The UE can send a first request to the network-side device using uplink messages during the random access procedure or using RRC signaling. The UE can choose one of the above methods based on the connection status between the UE and the network-side device.

[0274] For example, in some scenarios, the SIBx or posSIB containing the first information is not configured at the initial stage. This avoids unnecessary signaling overhead and reduces interference to neighboring cells. In such cases, the UE needs to actively request the network-side device to send the SIBx or posSIB. Subsequently, the network-side device sends the first information to the UE through system messages.

[0275] See Figure 12 As shown, taking a network-side device as a base station as an example, the method in this embodiment includes:

[0276] S1201. The base station sends an SIB broadcast. The SIB broadcast may include random access parameters, cell reselection parameters, neighbor cell information, time synchronization information, etc.

[0277] The SIB broadcast does not include SIBx or posSIB that carries the first information.

[0278] S1202, The UE sends a first request to the base station, which is used to request the base station to send first information.

[0279] That is, the UE requests SIBx or posSIB from the base station.

[0280] Since the UE is currently in a disconnected state, it can request SIBx or posSIB from the base station via uplink messages in the random access procedure. For example, when the UE accesses the base station using the four-step random access method, it can request SIBx or posSIB from the base station via the first message MSG1 or the third message MSG3 in the four-step random access procedure.

[0281] Request via MSG1: If the si-SchedulingInfo IE of SIB1 contains si-RequestConfigIE, the UE requests posSIB or SIBx using Msg1 of the RACH procedure through the Random Access Channel (RACH) parameters and resources configured in si-RequestConfigIE.

[0282] Request via MSG3: If the si-SchedulingInfo IE of SIB1 does not contain si-RequestConfigIE, the UE requests posSIB or SIBx by carrying the RRCsystemInfoRequest message in the Msg3 of the RACH procedure.

[0283] S1203. The base station sends a system message, which carries SIBx or posSIB for carrying the first information.

[0284] This step can be referred to. Figure 6 The detailed description of the illustrated embodiment S601 will not be repeated here for the sake of brevity.

[0285] S1204. The UE sends a positioning capability report to the base station, wherein the positioning capability report carries second information.

[0286] The UE embeds the second information into its positioning capability report and sends it to the base station. The base station obtains the second information from the UE's positioning capability report.

[0287] In this embodiment, when the UE sends its location capability report, the UE has already completed the random access procedure, and therefore, the UE is in a connected state.

[0288] In other scenarios, after the UE reports its positioning capability, the UE needs to obtain the first information. The UE can request SIBx or posSIB from the network-side device through RRC signaling, and then the network-side device can send the first information to the UE through, but is not limited to, broadcasting system messages.

[0289] See Figure 13 As shown, taking a network-side device as a base station as an example, the method in this embodiment includes:

[0290] S1301. The base station sends an SIB broadcast. The SIB broadcast may include random access parameters, cell reselection parameters, neighbor cell information, time synchronization information, etc.

[0291] This step and Figure 12 The embodiment S1201 shown is similar and can be referred to. Figure 12 The detailed description of the illustrated embodiments will not be repeated here for the sake of brevity.

[0292] S1302, The UE sends a location capability report to the network-side equipment.

[0293] The UE transmits positioning capability information to network-side equipment based on LPP, and the interaction process can refer to the interaction process defined by LPP.

[0294] In addition, when the UE reports its positioning capability, the UE is in RRC connected state.

[0295] S1303, the UE sends a third RRC signaling message to the network-side device. The third RRC signaling message carries a first request, which is used to request the network-side device to send first information.

[0296] When the UE is in connected mode, it can use RRC signaling to request the network-side device to send the first information.

[0297] S1304. The network-side device sends the first information to the UE according to the first request.

[0298] Network-side devices can send first information to the UE by sending system messages. These system messages carry either an SIBx or a posSIB containing the first information. The system messages can be broadcast or unicast, depending on the requirements.

[0299] The method in this embodiment is applicable to a UE requesting first information from a network-side device while in a connected state. As shown in this embodiment, the UE reports its positioning capability report first, followed by sending the first request. It should be understood that the order in which the UE sends the first request and reports its positioning capability report can also change. Furthermore, the network-side device can send the first information to the UE, but is not limited to, by broadcasting system messages. As mentioned above, the network-side device can also send the first information to the UE via existing uplink messages based on LPP, uplink messages added in the UE-preferred reporting process, or other newly added uplink messages based on LPP.
