Description

[0002] During the Rel-18 phase, Radio Access Network 1 (RAN1) is exploring the application of Artificial Intelligence (AI) / Machine Learning (ML) algorithms in the 5G Radio (NewRadio, NR) air interface, with a particular focus on enhancing Channel State Information (CSI) feedback, beam management, and positioning accuracy.

[0003] Taking AI positioning as an example, User Equipment (UE), Base Station (gNB), and Transmission Reception Point (TRP) can obtain channel measurements by measuring positioning reference signals (such as Positioning Reference Signal (PRS) or Sounding Reference Signal for Positioning (SRS-pos)). AI / ML models use these measurements to estimate user location or positioning intermediates (such as Time of Arrival (ToA), Line of Sight (LoS) / Non-Line of Sight (NLoS) metrics).

[0004] However, one of the challenges facing AI positioning is the poor generalization ability of the models.

[0127] The information reporting method, apparatus, device, and storage medium provided in this application allow an access device to report first information to the LMF (Local Management Function).

This facilitates faster and more accurate acquisition of performance monitoring results and allows monitoring of AI positioning performance under different positioning reference signal configurations, thereby determining the positioning reference signal configuration most suitable for the local AI model. Additionally, data from different configurations can be collected for model training or updates to adapt to the current environment. Moreover, a scheme for when to report the first information to the LMF is proposed, such as an explicit LMF request (i.e., reporting the first information based on an LMF request) or LMF-configured reporting conditions for the first information (i.e., second information). When the access device determines that the conditions are met based on the second information, it reports the first information to the LMF, which can optimize network resources while improving positioning performance.

[0145] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0146] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0147] Before introducing the embodiments of this application, in order to facilitate understanding of the embodiments of this application, the technical concept of this application will be briefly introduced in conjunction with related technologies:

[0148] With the continuous development of artificial intelligence technology, AI positioning research has gradually become an important direction in the field of communications. AI positioning, based on machine learning and deep learning algorithms, can analyze and process large amounts of signal data to achieve higher-precision positioning, which is of great significance in application scenarios such as mobile communications, the Internet of Things (IoT), and smart cities. AI positioning encompasses multiple application scenarios.

[0149] In some scenarios, the AI / ML model used for positioning can be deployed on the UE side, and the channel measurement entity is also the UE. The UE determines the model input by measuring the Positioning Reference Signal (PRS) resources transmitted by its own cell and neighboring cells, and the model output is an estimate of the UE's location. In other scenarios, the AI / ML model used for positioning is deployed on the network side, such as a base station (gNB) or transmission reception point (TRP), and the channel measurement entity is also the gNB / TRP. The gNB / TRP determines the model input by measuring the Sounding Reference Signal-Position (SRS-pos) resources transmitted by the UE serving its own cell and neighboring cells, and the model output is an estimate of intermediate positioning quantities.

[0150] The Location Management Function (LMF) network element is a key network element in a wireless communication network, responsible for managing and coordinating the location services of the UE. The LMF optimizes location performance through signaling interactions with the UE / gNB / TRP. For example, it processes location requests from the UE, network services, or external applications to determine appropriate location schemes to meet the requested accuracy, latency, and other requirements. Alternatively, it controls the transmission and measurement of location signals to ensure positioning accuracy and efficiency, and so on.

[0151] In relevant positioning schemes, the signaling interaction process between LMF and UE / gNB / TRP focuses on three aspects: capability reporting, auxiliary information transmission, and positioning information reporting. For example... Figures 1-4 As shown:

[0152] like Figure 1 As shown, the LMF can request the UE to report positioning capabilities based on the LTE Positioning Protocol (LPP). After receiving the capability request, the UE reports its positioning capabilities to the LMF, which may include PRS resource capabilities, PRS measurement capabilities, and PRS processing capabilities. Specifically, PRS resource capabilities indicate the maximum number of positioning frequency bands the UE supports, the maximum number of TRPs it supports, and the maximum number of PRS resources it supports for a single positioning frequency band. PRS measurement capabilities indicate whether the UE supports measuring the Reference Signal Received Power (RSRP) of PRS in Frequency Range 1 (FR1) / Frequency Range 2 (FR2) bands, how many TRPs a single TRP pair contains when measuring the Downlink Reference Signal Time Difference (DL-RSTD), the UE's Timing Error Group (TEG) capability, and whether the UE supports measuring the Reference Signal Received Path (RTS) power of the corresponding first path when measuring PRS resources. Power (RSRPP). PRS processing capability is used to indicate the PRS bandwidth supported by the UE within a single positioning frequency band, the length and period of the PRS processing window, the maximum number of PRS resources that the UE can process in a single time slot, and the priority of the UE in processing PRS and other downlink signals within a single PRS processing window.

[0153] like Figure 2 As shown, the UE can request auxiliary information from the LMF, and the LMF, upon receiving the request, sends the auxiliary information to the UE. Specifically, the auxiliary information that the LMF can send includes: the PRS ID and cell ID information corresponding to the TRP, synchronization error information between different TRPs, the PRS configuration of the TRP, the Synchronization Signal Block (SSB) information of the TRP, beam information of different PRSs, the geographic coordinate information of the TRP, the TEG information of the TRP, the LosS / NLoS indication information, the effective area information of the auxiliary information, and the Positioning Reference Unit (PRU) information, etc.

[0154] like Figure 3 As shown, the LMF can also request location information from the UE. After receiving the location information request, the UE sends the location information to the LMF. Specifically, the location information sent by the UE may include: timestamp, UE location coordinates, location error, location failure indication, and the reason for the location failure.

[0155] like Figure 4 As shown, the LMF can also request auxiliary information from the gNB / TRP. After receiving the auxiliary information request, the gNB / TRP sends the cell's configuration information to the UE. The LMF summarizes the auxiliary information reported by each gNB / TRP and then sends it to the UE for positioning calculation.

[0156] In the aforementioned positioning schemes, the signaling interaction between the LMF and UE mainly focuses on three aspects: capability reporting, auxiliary information transmission, and positioning information transmission; the signaling interaction between the LMF and gNB / TRP is mainly for auxiliary information transmission. However, for positioning schemes using AI models (or other positioning schemes with high randomness), due to the poor generalization ability of the models, the models (or other positioning schemes) may fail when the environment changes significantly. If the LMF cannot promptly sense changes occurring on the UE / gNB / TRP side and make relevant decisions, positioning performance will be severely affected.

[0157] In view of this, embodiments of this application provide an information reporting method, apparatus, device, and storage medium. The UE / TRP / gNB reports first information to the LMF, which may include performance monitoring results, first request information for requesting positioning reference signal configuration, a TRP set, or any combination of the above information. The LMF can make further decisions based on the information reported by the UE / TRP / gNB. For example, it can determine whether to disable or enable positioning functions (such as AI positioning functions) based on the reported performance monitoring results, thereby improving positioning performance; or configure relevant positioning reference signals for the UE / TRP / gNB based on the reported first request information, providing data support for the model to assist the AI ​​positioning model lifecycle management process, thereby improving positioning performance; or send positioning reference signals based on the reported TRP set (which may include downlink positioning or uplink positioning), thereby improving positioning performance; and so on. It is evident that by reporting the above-mentioned first information, the positioning performance of the UE or the positioning performance of the entire network can be effectively improved, especially the AI ​​positioning performance of the UE or the AI ​​positioning performance of the entire network.

[0158] It should be noted that the methods, apparatus, devices and storage media in this embodiment are based on the same application concept and have similar problem-solving principles. Therefore, the implementation of the apparatus, devices and storage media and methods can refer to each other, and repeated parts will not be described again.

[0159] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, 5G New Radio (NR) systems and their evolved communication systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network equipment. The systems may also include a core network component, such as the Evolved Packet Core (EPC) and the 5G Core Network (5GC).

[0161] The access devices involved in the embodiments of this application can be terminal devices, such as devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in 5G or 6G systems, the terminal device may be called User Equipment (UE). Wireless terminal devices can be USB storage devices, other personal computer memory devices, and dongles. They can also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) telephones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminal devices can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, remote terminals, access terminals, user terminals, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition; however, this application does not limit the scope of the embodiments.

[0162] The access device involved in the embodiments of this application can also be a network device, such as a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called a transmission access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The network device can be used to exchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, where the rest of the access network may include an Internet Protocol (IP) communication network. The network device can also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of this application may be an evolved Node B (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., which are not limited in the embodiments of this application.

[0163] Please refer to Figure 5 , Figure 5 This is a flowchart illustrating an information reporting method provided in an embodiment of this application, such as... Figure 5 As shown, the method may include:

[0164] Step S501: The access device sends first information to the positioning management function (LMF), the first information including at least one of the following: performance monitoring results; first request information for requesting positioning reference signal configuration; TRP set.

[0165] The access device can be a user equipment (UE), a network device (such as a gNB), an access point device (TRP), or other devices.

[0166] Optionally, the first information may include performance monitoring results, and LMF can make decisions based on the performance monitoring results, such as enabling or disabling the AI ​​positioning function.

[0167] Optionally, the first information may include first request information for requesting the configuration of the positioning reference signal. The positioning reference signal configuration is a set of parameters used to indicate the location of the positioning reference signal transmitting node and / or the occupied time-frequency resource location. The access device can request the positioning reference signal configuration in two ways: one is to directly request specific parameters (such as the positioning reference signal transmission characteristics described later), and the other is to request the identifier corresponding to the parameter if there is a predefined relationship between the parameter and the identifier. The positioning reference signal configuration requested by the access device can be used to determine the subsequent AI positioning calculation results and / or performance monitoring results, thereby improving positioning performance. It should be noted that the positioning reference signal in this embodiment is a broad concept, which may include a positioning reference signal (PRS) or a sounding reference signal position (SRS-pos), used to support the positioning and measurement of the access device.

[0168] Optionally, the first information may include a set of TRPs. In an optional implementation, the TRP set may include TRP identifiers of one or more access point TRPs, indicating the transmitting node corresponding to the positioning reference signal that the access device requests to measure. The access device reports the requested TRP set, which includes one or more TRP identifiers, to the LMF to indicate to the LMF which TRPs (downlink positioning) or which TRP services the access device actually expects to receive positioning reference signals from access devices such as UEs (uplink positioning). In this way, the access device can receive positioning reference signals from multiple expected TRPs (downlink positioning) or multiple expected TRP services from UEs (uplink positioning), thereby improving positioning performance.

[0169] Optionally, the first information may also include any combination of performance monitoring results, first request information, and TRP sets. The relevant principles and effects can be found above and will not be elaborated upon here. In addition to the information mentioned above, the first information may also include other reported information.

[0170] Next, we will further introduce the various pieces of information mentioned in the first piece of information above:

[0171] In an optional implementation, the performance monitoring results may include at least one of the following: one or more performance monitoring metrics; statistical results of multiple performance monitoring metrics; first decision result information indicating whether the AI ​​positioning function is applicable; and second decision result information indicating whether the AI ​​model used for positioning is applicable.

[0172] Optionally, the performance monitoring results may include one or more performance monitoring metrics, which can be used to determine whether the AI ​​localization function and / or the AI ​​model used for localization calculations are suitable for the current environment. For example, the performance monitoring metrics may include at least one of the following: localization error, variance of the AI ​​model output used for localization, and confidence level.

[0173] In some use cases of AI positioning, the output of the AI ​​model is an estimated value of the UE's location, and the positioning error is the difference between the AI ​​model output and the tag. The tag can be the UE location calculated by the LMF using non-AI methods, or the user's location coordinates provided by the UE or PRU whose location is known. By reporting the positioning error, the LMF can quickly determine whether the AI ​​positioning function is suitable for the current environment, and / or whether the AI ​​model used for positioning calculations is appropriate based on the magnitude of the error.

[0174] The variance of the AI ​​model output reflects the stability and reliability of the model's prediction results. For example, lower variance indicates more consistent model output and more reliable prediction results, while high variance means that the model performs unstablely under different conditions. By reporting the variance of the AI ​​model output, LMF can quickly determine whether the AI ​​positioning function and / or the AI ​​model used for positioning calculations are suitable for the current environment based on the magnitude of the variance.

[0175] The confidence level, or the degree to which the AI ​​model is confident in its predictions, is usually expressed as a percentage. A higher confidence level indicates that the AI ​​model's predictions are more accurate, thus determining the reliability of the model's predictions. By reporting the AI ​​model's confidence level, LMF can quickly determine whether the AI ​​positioning function and / or the AI ​​model used for positioning calculations are suitable for the current environment.

[0176] Optionally, the performance monitoring metrics can be any combination of the above-mentioned performance monitoring metrics. The relevant principles and effects can be found above, and will not be repeated here. In some embodiments, in addition to the above-mentioned performance monitoring metrics, other metrics may be included, and this embodiment does not particularly limit this.

[0177] In an optional implementation, the performance monitoring results may include statistical results of multiple performance monitoring indicators. These statistical results may include at least one of the following: the geometric mean of the multiple performance monitoring indicators, the weighted average, the total number of performance monitoring indicators, and the number of indicators that did not reach the monitoring indicator threshold.

[0178] The geometric mean of multiple performance monitoring metrics is the nth root of the product of the values ​​of these metrics (where n is the number of metrics). In performance monitoring, the geometric mean can be used to comprehensively evaluate multiple metrics, assessing metrics with different magnitudes or units, providing a more balanced overall view of performance, thereby improving the accuracy of performance monitoring metrics.

[0179] The weighted average is calculated by multiplying each indicator value by a weight (which can be adjusted adaptively by those skilled in the art based on practical applications or experience), and then summing the results. The weights reflect the importance of each indicator in the overall evaluation. By adjusting the weights, the importance of certain indicators can be highlighted according to positioning needs or system priorities, thereby obtaining evaluation results that better reflect actual positioning requirements.

[0180] Among them, the total number of performance monitoring indicators, that is, the total number of performance monitoring indicators of the access devices, helps to evaluate the overall positioning performance.

[0181] The number of indicators that did not reach the monitoring indicator threshold (thresholds can be adaptively set by those skilled in the art based on actual applications or experience, and the same or different thresholds can be set for different indicators) can be either the number of indicators less than the monitoring indicator threshold or the number of indicators greater than the monitoring indicator threshold.

[0182] The statistical results of the above-mentioned performance monitoring indicators help to quantitatively analyze the performance monitoring indicators and improve the accuracy of the performance monitoring results. In some embodiments, the statistical results can be any combination of the above-mentioned statistical information. In addition, other statistical information may be included besides the above-mentioned statistical information, which is not particularly limited in this embodiment.

[0183] In an optional implementation, the performance monitoring results may include first decision result information, which can be used to indicate whether the AI ​​positioning function is applicable (hard decision result), the probability of application (soft decision result), etc. Specifically, the first decision result information includes at least one of the following:

[0184] The type of first judgment result;

[0185] The first judgment result;

[0186] When the first decision result is of the hard decision type, the first decision result includes a first indicator bit, which is used to indicate whether the AI ​​positioning function is applicable; when the first decision result is of the soft decision type, the first decision result includes a first decision value, which is used to indicate the probability that the AI ​​positioning function is applicable.

[0187] The type of the first decision result indicates whether it is a hard decision or a soft decision. When the first decision result is a hard decision, it can be an indicator bit; for example, a bit of 0 indicates that it is not applicable, and a bit of 1 indicates that the AI ​​function is applicable in the current environment. When the first decision result is a soft decision, it can be a decision value, such as a percentage from 0 to 100, where a larger value indicates a higher probability that the AI ​​function is applicable in the current environment.

[0188] By reporting the first judgment result information, LMF can quickly determine whether the AI ​​function is applicable and / or the probability of its applicability, so as to make the next step decision quickly, such as turning the AI ​​positioning function on or off, thereby improving the AI ​​positioning performance.

[0189] In an optional implementation, the performance monitoring results may include second decision result information, which can be used to indicate whether the AI ​​model is applicable or the probability of its applicability. Specifically, the second decision result information may include at least one of the following:

[0190] Types of second-instance judgments;

[0191] The second judgment result;

[0192] When the second decision result is of the hard decision type, the second decision result includes a second indicator bit, which is used to indicate whether the AI ​​model used for localization is applicable; when the second decision result is of the soft decision type, the second decision result includes a second decision value, which is used to indicate the probability that the AI ​​model used for localization is applicable.

[0193] It should be noted that the second judgment result information mentioned above is similar in principle and effect to the first judgment result information mentioned above. The main difference is that the second judgment result information is a judgment result information for the AI ​​model. For relevant descriptions, please refer to the first judgment result information mentioned above. It will not be repeated here.

[0194] In an optional implementation, the first information may include first request information, which may include at least one of the following:

[0195] First positioning reference signal request;

[0196] Second positioning reference signal request;

[0197] The first positioning reference signal request is used to request a first positioning reference signal configuration, which is used at least to determine the subsequent positioning calculation results; the second positioning reference signal request is used to request a second positioning reference signal configuration, which is used at least to determine the subsequent performance monitoring results.

[0198] The first positioning reference signal request indicates that the access device (such as UE / gNB / TRP) requests the LMF to configure a positioning reference signal, which is at least used to determine the subsequent positioning calculation results. The second positioning reference signal indicates that the access device (such as UE / gNB / TRP) requests the LMF to configure a positioning reference signal, which is at least used to determine the subsequent performance monitoring results.

[0199] In one example, the first request information includes a first positioning reference signal request, which may include at least one of the following: a first positioning reference signal transmission characteristic, and a first positioning reference signal configuration identifier. In this case, the first positioning reference signal request is used to request a first positioning reference signal configuration, which can be used to determine subsequent partial or complete positioning calculation results, and / or, subsequent partial or complete performance monitoring results.

[0200] In this example, the first request information may contain only one positioning reference signal request, i.e., a first positioning reference signal request (or only a second positioning reference signal, and so on). In one case, the first positioning reference signal request can be used to request positioning reference signal configuration to determine subsequent partial or complete positioning calculation results and subsequent partial or complete performance monitoring results. In another case, the first positioning reference signal request can be used to request positioning reference signal configuration to determine subsequent partial or complete positioning calculation results. In some cases, the first positioning reference signal request can also be used to request positioning reference signal configuration to determine subsequent partial or complete performance monitoring results.

[0201] Optionally, the first positioning reference signal transmission feature may include at least one of the following: a first positioning reference signal period; a first positioning reference signal frequency domain bandwidth; the number of symbols occupied by the first positioning reference signal resources; a first positioning reference signal frequency domain density; a first positioning reference signal period scaling factor; the first positioning reference signal period scaling factor being a scaling ratio between the first positioning reference signal period and the positioning reference signal period configured in the current network.

[0202] In another example, the first request information includes a second positioning reference signal request, which may include at least one of the following: a second positioning reference signal transmission characteristic and a second positioning reference signal configuration identifier. In this case, the second positioning reference signal configuration can be used to determine some or all of the subsequent performance monitoring results.

[0203] Optionally, the second positioning reference signal transmission feature may include at least one of the following: second positioning reference signal period; second positioning reference signal frequency domain bandwidth; number of symbols occupied by the second positioning reference signal resources; second positioning reference signal frequency domain density; second positioning reference signal period scaling factor; the second positioning reference signal period scaling factor is a scaling ratio of the second positioning reference signal period to the positioning reference signal period configured in the current network.

[0204] Optionally, when the first request information includes a first positioning reference signal configuration identifier / a second positioning reference signal configuration identifier, the access device needs to receive one or more positioning reference signal configuration information sent by the LMF before sending the first information. The positioning reference signal configuration information includes at least one of the following: a configuration identifier; a positioning reference signal configuration. The first positioning reference signal configuration identifier / the second positioning reference signal configuration identifier is one or more of the configuration identifiers included in the one or more positioning reference signal configuration information.

[0205] In some examples, the first request information includes a first positioning reference signal request and a second positioning reference signal request. That is, the first request information simultaneously contains both a first positioning reference signal request and a second positioning reference signal request. In this case, the access device requests different positioning reference signal configurations from the LMF, which are used to determine some or all subsequent performance monitoring results and some or all AI positioning calculation results, respectively. Based on this, the system supports access devices (such as UE / gNB / TRP) requesting preferred positioning reference signal transmission characteristics from the LMF to determine some or all subsequent performance monitoring results (e.g., by requesting a smaller period and higher frequency domain density to improve the accuracy of subsequent performance monitoring results); and / or, the system supports access devices requesting preferred positioning reference signal configuration identifiers while reporting performance monitoring results to the LMF, to determine some or all subsequent performance monitoring results (e.g., by receiving different positioning reference signal configurations from the LMF in advance and requesting preferred configuration identifiers to monitor the performance of AI positioning under different configurations, determine the configuration most suitable for the local model, or collect data under different configurations for model training or updating).

[0206] In some embodiments, in addition to the performance monitoring report, first request information, and TRP set mentioned above, the first information may also include other reporting information, such as at least one of the following: the reason why the AI ​​positioning function is not applicable; the reason why the AI ​​model used for positioning is not applicable; indication information for indicating whether the reporting event configured on the network side has occurred; and the first event type of the reporting event that has occurred.

[0207] Specifically, by including the reason why the AI ​​positioning function is not applicable / the reason why the AI ​​model used for positioning is not applicable in the first information, the access device can determine whether to update the network configuration based on the reason why the AI ​​positioning function / AI model is not applicable, thereby ensuring the performance of AI positioning. Optionally, the reason why the AI ​​positioning function is not applicable may be that the current network's positioning reference signal configuration does not match the positioning reference signal configuration corresponding to the AI / ML model.

[0208] If the network side configures one or more reporting events, when the access device determines that one or more reporting events have occurred, the access device can report the first information and carry indication information in the first information to indicate whether the reporting events configured by the network side have occurred.

[0209] Among them, the first event type of the reported event is used to instruct the access device to determine the type of the reported event that has occurred, and the LMF side can quickly sense the reported event that has occurred based on the first event type.

[0210] Figure 6 A flowchart illustrating another information reporting method provided in this application embodiment is shown below. Figure 5 Based on the corresponding embodiment, this embodiment can report the first information to the LMF based on the LMF's request. The above step S501 of sending the first information to the LMF can be refined into the following steps:

[0211] Step S5011: Upon receiving the second request information sent by the LMF, send first information to the LMF according to the second request information, wherein the second request information is information used to request the first information.

[0212] Instead of proactive or real-time reporting of first information by the access device, reporting first information based on LMF requests reduces the frequency of first information reporting, minimizes unnecessary information transmission, thereby reducing network load and improving network resource utilization efficiency, especially in high-traffic environments. Furthermore, it effectively protects user privacy, preventing unnecessary leakage or misuse of location data.

[0213] In an optional implementation, the second request information includes at least one of the following: a bitmap; field information; a time window for indicating the reporting time of the first information; the bitmap includes one or more bits: when the bitmap includes one bit, the bit is used to indicate whether the first information is requested; when the bitmap includes multiple bits, each bit corresponds to one item in the first information, and the bitmap is used to indicate that one or more items of the first information are requested; the field information includes one or more fields: when the field information includes one field, the field is used to indicate whether the first information is requested; when the field information includes multiple fields, each field corresponds to one item in the first information, and the field information is used to indicate that one or more items of the first information are requested.

[0214] The bitmap can be a structure consisting of one or more bits. Optionally, when the bitmap contains only one bit, this bit can be used to indicate whether the first information is requested. For example, a bit of 1 indicates that the LMF requests the first information from the access device (it can request all information in the first information, or it can request one or more information in the first information), and a bit of 0 indicates that the LMF does not request the first information from the access device. Optionally, when the bitmap contains multiple bits, each bit corresponds to an item in the first information, and the bitmap is used to indicate whether one or more items in the first information are requested. The value of each bit corresponds to whether a specific item in the first information is requested.

[0215] The field information can consist of one or more fields. When the field information contains one field, that field can be used to indicate whether the first information is requested. When the field information contains multiple fields, each field corresponds to an item in the first information, and the field information can be used to indicate whether one or more items of the first information are requested.

[0216] Based on the above-mentioned second request information format design, LMF is allowed to flexibly request specific information items, support requests for single or multiple information items, and the information transmission time can be specified through time windows, which is conducive to the efficient transmission of positioning data in the communication system and the efficient management of network resources.

[0217] Figure 7 This is a flowchart illustrating another information reporting method provided in an embodiment of this application. Figure 5Based on the corresponding embodiment, this embodiment reports the first information by receiving the second information sent by the LMF. When the access device determines that a reporting event configured on the network side has occurred, the first information is reported. Specifically, in addition to the above step S501, step S701 may also be included, and step S501 is further divided into step S5012 and step S5013.

[0218] Step S701: Receive the second information sent by the LMF, the second information including one or more reporting event configurations; each reporting event configuration includes at least one of the following: event type; event parameters; when the reporting event configuration includes an event type, the first event type in the first information is one or more of the event types included in the second information.

[0219] In this embodiment, by receiving the second information sent by the LMF, the access device (such as UE / gNB / TRP) determines whether the corresponding reporting event has occurred based on the corresponding event parameters and performance monitoring indicators configured for each reported event. When the access device determines that one or more reporting events have occurred, it sends the first information to the LMF. The performance monitoring indicators can be locally calculated and stored by the access device, and / or sent by the LMF; this embodiment does not impose any particular limitation on this.

[0220] Step S5012: Determine whether a reporting event has occurred based on the event parameters and performance monitoring indicators included in the second information.

[0221] In one example, the event parameters may include at least one of the following: a first performance monitoring metric threshold N1, the number of statistics T, and a first invalid number threshold M1; the above step S5012 determines whether a reporting event has occurred based on the event parameters and performance monitoring metrics included in the second information, which can be done in the following way:

[0222] The first time a performance monitoring indicator fails to reach the threshold N1 of the first performance monitoring indicator is taken as the starting position for statistics. From the starting position, T performance monitoring indicators are counted continuously.

[0223] If at least M1 out of T performance monitoring metrics fail to reach the first performance monitoring metric threshold N1, then the reported event is determined to have occurred.

[0224] Optionally, the access device can use the position where the performance monitoring indicator first fails to reach the performance monitoring indicator threshold N1 (which could be the first time it is greater than, less than, or other situations where the performance monitoring indicator threshold N1 is not reached) as the starting position for statistics. From the starting position for statistics, the access device continuously monitors T performance monitoring indicators. If at least M1 performance monitoring indicators (or more than M1 performance indicators) among the T performance monitoring indicators are greater than / less than the performance monitoring indicator threshold N1, the access device can determine that an event has occurred.

[0225] It should be noted that those skilled in the art can adaptively set or adjust the above-mentioned first performance monitoring index threshold N1, statistical count T, and first invalid count threshold M1 based on actual applications or experience values. This embodiment does not impose any particular limitations on this.

[0226] In another example, the event parameters may include at least one of the following: a second performance monitoring metric threshold N2, and a second invalidity count threshold M2; step S5012 above determines whether a reporting event has occurred based on the event parameters and performance monitoring metrics included in the second information, which can be done in the following manner:

[0227] The reported event is determined to have occurred when M2 consecutive performance monitoring metrics fail to reach the second performance monitoring metric threshold N2.

[0228] Compared to the above example, the event parameters in this embodiment may not include the number of times T, and may be determined solely based on the second performance monitoring index threshold N2 and the second invalid number threshold M2. Optionally, if the M2 performance monitoring indices continuously stored (or received from LMF) by the access device do not reach (e.g., greater than or less than) the second performance monitoring index threshold N2, the access device can determine that an event has occurred.

[0229] In some examples, the event parameters may include a third performance monitoring indicator threshold N3; the above step S5012 determines whether a reporting event has occurred based on the event parameters and performance monitoring indicators included in the second information, which can be done in the following way: when the performance monitoring indicator is not monitored to reach the third performance monitoring indicator threshold N3, it can be determined that a reporting event has occurred.

[0230] In some examples, the second information may include multiple reporting events, such as: event type 1: event parameters are the first performance monitoring indicator threshold N1, the number of statistics T, and the first invalid number threshold M1; event type 2: event parameters are the second performance monitoring indicator threshold N2 and the second invalid number threshold M2; event type 3: event parameters are the first performance monitoring indicator threshold N3, and so on.

[0231] It should be noted that the above-mentioned first performance monitoring indicator threshold N1, second performance monitoring indicator threshold N2, and third performance monitoring indicator threshold N3 are only used to distinguish similar objects and have no special meaning. They can be the same threshold or different thresholds.

[0232] Step S5013: When the reported event occurs, send the first information to the LMF.

[0233] In this embodiment, by configuring reporting events, unnecessary first information transmission can be reduced. For example, the access device only reports the first information to the LMF when one or more reporting events occur. This can reduce the reporting frequency of the first information and reduce unnecessary information transmission while effectively ensuring the performance of AI positioning, thereby reducing the network burden.

[0234] Figures 8a-8c This is a flowchart illustrating another information reporting method provided in an embodiment of this application. Figure 5 Based on the corresponding embodiments, this embodiment can also receive a third positioning reference signal configuration and / or a fourth positioning reference signal configuration sent by the LMF, and use the third positioning reference signal configuration and / or the fourth positioning reference signal configuration to determine subsequent performance monitoring results and / or positioning calculation results, thereby improving the reporting accuracy of subsequent performance monitoring results or improving positioning performance. Figure 8a As shown, an example of receiving a third positioning reference signal configuration is illustrated. In addition to step S501 described above, the method provided in this embodiment may also include the following steps S801 and S802.

[0235] Step S801: Receive the third positioning reference signal configuration sent by the LMF, wherein the third positioning reference signal configuration includes the positioning reference signal configuration updated according to the first request information.

[0236] The third positioning reference signal configuration sent by the LMF can be the positioning reference signal configuration updated by the LMF based on the first information of the access device (such as the first information carrying the first request information). For example, the third positioning reference signal configuration can be the updated positioning reference signal configuration obtained by the access device sending the first information to the LMF and the LMF deciding whether to update the current network's positioning reference signal configuration based on the first positioning reference signal request.

[0237] Optionally, the LMF can determine whether to update or not update the positioning reference signal configuration based on the positioning reference signal request from the access device. If it decides to update, it can send a third positioning reference signal configuration to the access device. If it decides not to update, it can send the reason for the update failure to the access device.

[0238] Optionally, the third positioning reference signal configuration may be a positioning reference signal configuration updated according to the first positioning reference signal request in the first request information. For example, in one case, the first positioning reference signal request is used to request a positioning reference signal configuration, which is used to determine some or all of the subsequent performance monitoring results, and in this case, the third positioning reference signal configuration is used to determine some or all of the subsequent performance monitoring results; in another case, the first positioning reference signal request is used to request a positioning reference signal configuration, which is used to determine some or all of the subsequent performance monitoring results and some or all of the positioning calculation results, and in this case, the third positioning reference signal configuration is used to determine some or all of the subsequent performance monitoring results and some or all of the positioning calculation results; in yet another case, the first positioning reference signal request is used to request a positioning reference signal configuration, which is used to determine some or all of the subsequent positioning calculation results, and in this case, the third positioning reference signal configuration is used to determine some or all of the subsequent positioning calculation results.

[0239] Step S802: Based on the configuration of the third positioning reference signal, at least some subsequent performance monitoring results are determined.

[0240] In this process, after receiving the third positioning reference signal configuration, the access device uses the third positioning reference signal configuration to determine part or all of the subsequent performance monitoring results; or uses the third positioning reference signal configuration to determine part or all of the subsequent performance monitoring results and part or all of the subsequent positioning calculation results; or uses the third positioning reference signal configuration to determine part or all of the subsequent positioning calculation results. Using the third positioning reference signal configuration to determine part or all of the subsequent performance monitoring results, for example, performing performance monitoring based on the corresponding third positioning reference signal configuration to generate subsequent performance monitoring results, helps to obtain performance monitoring results more quickly and accurately in the future.

[0241] In another alternative implementation, such as Figure 8b As shown, an example of receiving a fourth positioning reference signal configuration is illustrated. In addition to step S501 described above, the method provided in this embodiment may also include steps S803 and S804:

[0242] Step S803: Receive the fourth positioning reference signal configuration sent by the LMF, wherein the fourth positioning reference signal configuration includes the positioning reference signal configuration updated according to the first request information.

[0243] Optionally, the fourth positioning reference signal configuration can be the positioning reference signal configuration updated according to the second positioning reference signal request in the first request information. The fourth positioning reference signal configuration is similar to the third positioning reference signal configuration described above, and the relevant explanations will not be elaborated here.

[0244] Step S804: Based on the configuration of the fourth positioning reference signal, at least part of the subsequent positioning calculation results are determined.

[0245] After receiving the fourth positioning reference signal configuration, the access device can perform positioning calculations based on the fourth positioning reference signal configuration and monitor the AI ​​positioning performance under different positioning reference signal configurations, thereby determining the positioning reference signal configuration that best matches the local AI model and improving positioning performance.

[0246] In some alternative implementations, such as Figure 8c The system can also simultaneously receive the third positioning reference signal configuration and the fourth positioning reference signal configuration (step S805), and determine some or all of the subsequent performance monitoring results and positioning calculation results based on the third positioning reference signal configuration and the fourth positioning reference signal configuration (step S806). The relevant principles and effects will not be elaborated here.

[0247] In summary, compared to the positioning process in related technologies where only capability information, auxiliary information, and positioning information are exchanged between the device side and the LMF side, for AI positioning, the device side and the LMF side should also exchange information in a timely manner regarding the AI ​​positioning function and / or the performance monitoring results of the AI / ML model used for positioning, to ensure AI positioning performance. The information reporting method provided in this application embodiment supports the access device (such as UE / gNB / TRP) reporting first information (such as performance monitoring results) to the LMF. At the same time, the UE / gNB / TRP can also request a preferred positioning reference signal configuration from the LMF to determine the subsequent positioning calculation results and / or performance monitoring results. This scheme helps to obtain performance monitoring results faster and more accurately, and can monitor the AI ​​positioning performance under different positioning reference signal configurations, thereby determining the positioning reference signal configuration most suitable for the local AI model; furthermore, it can collect data under different configurations for model training or updates to adapt to the current environment. Furthermore, this application also proposes a scheme for when the UE / gNB / TRP reports the performance monitoring results to the LMF, such as an explicit request from the LMF (i.e., reporting the performance monitoring results based on the LMF's request), or the LMF configuring performance monitoring result reporting conditions, and when the UE / gNB / TRP determines that the conditions are met, it reports the performance monitoring results to the LMF.

[0248] Based on the same technical concept, this application also provides an information reporting method, which can be applied to LMF. Figure 9 This is a flowchart illustrating the information reporting method, such as... Figure 9 As shown, the method may include the following steps:

[0249] Step S901: The LMF receives first information sent by the access device, the first information including at least one of the following: performance monitoring results; first request information for requesting the configuration of the positioning reference signal; TRP set.

[0250] In an optional implementation, the first information further includes at least one of the following: the reason why the AI ​​positioning function is not applicable; the reason why the AI ​​model used for positioning is not applicable; and indication information for indicating whether a reporting event configured on the network side has occurred.

[0259] In an optional implementation, the method may further include the following steps: sending one or more positioning reference signal configuration information to the access device, the positioning reference signal configuration information including at least one of the following: configuration identifier; positioning reference signal configuration; wherein, the first positioning reference signal configuration identifier, and / or, the second positioning reference signal configuration identifier is one or more of the configuration identifiers in the one or more positioning reference signal configuration information.

[0260] In an optional implementation, the first positioning reference signal transmission feature includes at least one of the following: a first positioning reference signal period; a first positioning reference signal frequency domain bandwidth; the number of symbols occupied by the first positioning reference signal resources; a first positioning reference signal frequency domain density; a first positioning reference signal period scaling factor; the first positioning reference signal period scaling factor is a scaling ratio between the first positioning reference signal period and the positioning reference signal period configured in the current network.

[0261] In an optional implementation, the second positioning reference signal transmission feature includes at least one of the following: a second positioning reference signal period; a second positioning reference signal frequency domain bandwidth; the number of symbols occupied by the second positioning reference signal resources; a second positioning reference signal frequency domain density; a second positioning reference signal period scaling factor; the second positioning reference signal period scaling factor being a scaling ratio between the second positioning reference signal period and the positioning reference signal period configured in the current network.

[0262] In an optional implementation, the TRP set includes TRP identifiers for one or more access point TRPs, indicating the transmitting node corresponding to the positioning reference signal for which the access device requests measurement.
