Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless communication technology, and in particular to a management method, device and storage medium for an AI / ML model or function. Background Art
[0002] The unilateral model deployed on the terminal (also called user equipment (UE)) side, or the part of the bilateral model that belongs to the UE side, may be trained and generated by the UE manufacturer, chip manufacturer or third-party service provider. The network side (NW) is not clear about how the artificial intelligence (AI) / machine learning (ML) model on the UE side is trained. The intrinsic relationship between the input and output learned by the AI / ML model comes from the dataset used in its training process. Different datasets represent different wireless environments. If the current NW environment is similar to the environment represented by the training dataset corresponding to the current AI / ML model or function of the UE, and the intrinsic relationship between the input and output is also similar, the performance of the AI / ML method is often better, and vice versa.
[0003] In order to improve performance, from the perspective of model life cycle management (LCM), if the UE deploys multiple AI / ML models and different models correspond to different training environments, it can select and switch to the most suitable model; or it can update and fine-tune the model deployed by the UE to make it more suitable for the current network environment and improve performance. However, there is currently no specific mechanism to assist the NW or UE in performing the more appropriate LCM operations mentioned above that are more conducive to improving performance.

[0284] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.
[0285] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.
[0286] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.
[0287] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0288] In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application are first introduced.
[0289] AI / ML model refers to a data-driven algorithm that can infer and predict outputs based on certain inputs. Depending on the data collected during the training process, a model often has certain adaptation scenarios. UE can manage the AI / ML model on the UE side. If the AI / ML model on the UE side is visible to the NW, the NW can manage the model on the UE side.
[0290] AI / ML functionality refers to the AI / ML reasoning function of UE on certain functions (such as channel state information (CSI) compression, beam prediction, and positioning). This function is visible to NW, and NW can manage it at the functionality level. However, NW does not know how many AI / ML models UE uses to implement AI / ML functionality. Therefore, model-level management is generally managed by UE itself.
[0291] If the manager of the LCM of the AI / ML model or function on the UE side is the NW, it may be difficult for the NW to give appropriate instructions on the selection / switching / updating of the UE model because it is not clear about the applicability of the model on the UE side or the data set used during the training of the model on the UE side.
[0292] Once the NW performs incorrect and inappropriate LCM management, such as activating an AI / ML model with poor performance, it may lead to a decrease in UE transmission performance, a decrease in NW performance, and cause the UE to waste computing power and storage overhead to run AI / ML models or functions.
[0293] In order to solve the above problems, the present application embodiment proposes a management method for AI / ML models or functions, which has the following advantages:
[0294] (1) It can quantitatively characterize information such as the environment, site, and data set, making it possible to use them as auxiliary information.
[0295] (2) The UE can send auxiliary information to the NW to assist the NW in performing accurate and appropriate lifecycle management of the AI / ML model or function on the UE side according to the matching of the AI / ML model or function on the UE side with the current cell environment, configuration, and conditions, thereby improving the transmission performance of the UE and the overall performance of the network and avoiding unnecessary AI / ML computing / storage overhead.
[0296] Figure 1 One of the flow charts of the method for managing the AI / ML model or function provided in the embodiment of the present application, the method is applied to the terminal, such as Figure 1 As shown, the method comprises the following steps:
[0297] Step 100: Send auxiliary information related to the AI / ML model or function to the network device, where the auxiliary information includes first information applicable to the AI / ML model or function, and / or first information corresponding to a training data set of the AI / ML model or function, and the first information is used by the network device to manage the AI / ML model or function. The sending to the network device here only means that the terminal sends the relevant information via a wireless signal, and the destination receiving device is the network device, and the network device obtains the relevant information by receiving the wireless signal.
[0298] Specifically, the AI / ML model or function in this application can be an AI / ML model or function on the terminal side or an AI / ML model or function deployed on other devices, which is not limited in this application. For ease of understanding, the following text takes the AI / ML model or function on the terminal side as an example, but it should be understood that AI / ML models or functions on other sides can also be applied here.
[0299] The terminal can be deployed with a terminal-side unilateral model or the terminal-side part of a bilateral model. The model deployed in the terminal can be trained and generated by the terminal manufacturer, chip manufacturer or third-party service provider. Network equipment (such as base stations) can be the LCM manager of the AI / ML model or function on the terminal side.
[0300] In order to ensure the performance of the AI / ML model or function on the terminal side in the current network, the terminal can send auxiliary information related to the AI / ML model or function on the terminal side to the network device to assist the network device in managing the AI / ML model or function on the terminal side.
[0301] Auxiliary information related to the AI / ML model or function on the terminal side can be collected by the terminal and sent to the network device, or forwarded to the network device by a third-party server (such as an AI / ML model supplier, Over The Top (OTT) server, etc.) through the terminal, or sent to the network device by a third-party server through a non-air interface method.
[0302] The first information can be used to indicate one or more of the scenarios (e.g., the scenarios and heights where the network device is located), configurations (e.g., reference signal configuration information), and conditions (e.g., data distribution characteristics). The first information applicable to the terminal-side AI / ML model or function can be used to indicate one or more of the applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function. The first information corresponding to the training data set of the terminal-side AI / ML model or function can be used to indicate information related to the training data set of the terminal-side AI / ML model or function. The network device can determine one or more of the applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function based on the information related to the training data set of the terminal-side AI / ML model or function. That is, the auxiliary information related to the terminal-side AI / ML model or function can be used to directly or indirectly indicate one or more of the applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function. The network device can manage the terminal-side AI / ML model or function based on one or more of the current scenarios, configurations, and conditions of the terminal-side AI / ML model or function in combination with one or more of the applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function.
[0303] Each AI / ML model or function, or each training data set of an AI / ML model or function may correspond to one piece of auxiliary information, or to multiple pieces of auxiliary information. Multiple pieces of auxiliary information indicate that the AI / ML model or function is applicable to multiple scenarios / configurations / conditions, or that the training data set of the AI / ML model or function exists in multiple scenarios / configurations / conditions when it is collected.
[0304] If the terminal has multiple AI / ML models or multiple AI / ML functions, the terminal may indicate the auxiliary information corresponding to each AI / ML model or each AI / ML function, or divide the AI / ML models or AI / ML functions into several sets and indicate the auxiliary information corresponding to each model set or function set. The terminal may also indicate the auxiliary information corresponding to the training data set of each AI / ML model or each AI / ML function, or divide the AI / ML models or AI / ML functions into several sets and indicate the auxiliary information corresponding to the training data set of each model set or function set.
[0305] In one implementation, the network device may compare one or more applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function with the current scenarios, configurations, and conditions of the network device, and activate the terminal-side AI / ML model or function when all or part of the scenarios match.
[0306] In one implementation, the network device may compare one or more applicable scenarios, applicable configurations, and applicable conditions of the terminal-side AI / ML model or function with the current scenarios, configurations, and conditions of the network device. When the applicable scenarios, applicable configurations, and applicable conditions that "significantly affect the generalization performance" (i.e., have a significant impact on the performance of the terminal-side AI / ML model or function) can match, the AI / ML model or function on the terminal side is activated; if the applicable scenarios, applicable configurations, and applicable conditions that "significantly affect the generalization performance" cannot match, the AI / ML model or function on the terminal side is deactivated.
[0307] In one implementation, the network device may compare one or more applicable scenarios, applicable configurations, and applicable conditions of a terminal-side AI / ML model or function with the current scenario, configuration, and conditions of the network device. When there are multiple terminal-side AI / ML models or functions that can be matched, the terminal-side AI / ML model or function that best matches the current scenario, configuration, and conditions of the network device may be selected for activation, or switched to the terminal-side AI / ML model or function that best matches the current scenario, configuration, and conditions of the network device.
[0308] In one implementation, the network device may compare multiple configurations when the training data set corresponding to the terminal side AI / ML model or function is collected with the current configuration of the network device. If the current configuration of the network device belongs to one of the configurations when the training data set is collected, it is considered that the terminal side AI / ML model or function can work normally under the configuration of this cell, and the terminal side AI / ML model or function is activated.
[0309] In one implementation, the network device may compare the network device identifier when the training data sets corresponding to the multiple AI / ML models or functions of the terminal were collected and the current network device identifier, and if it is found that the current cell belongs to the cell from which the training data sets were collected, it is considered that the terminal-side AI / ML model or function can work normally in this cell, and the terminal-side AI / ML model or function is activated.
[0310] In one implementation, the network device may compare the network device identifier when the training data set corresponding to multiple AI / ML models or functions of the terminal was collected and the current network device identifier, and find that the current cell does not belong to the cell from which the training data set was collected, but judges that the wireless environment of the current cell is similar to the wireless environment of the cell when the data was collected. It can also be considered that the terminal-side AI / ML model or function can work normally in this cell, and the terminal-side AI / ML model or function is activated.
[0311] The management method of the AI / ML model or function provided in the embodiment of the present application can be applied to the fifth generation mobile communication system (the 5th generation mobile communication, 5G) new radio (New Radio, NR) system, and can also be applied to other systems that require AI / ML model-assisted information interaction.
[0312] The AI / ML model or function management method provided in the embodiment of the present application is that the terminal sends auxiliary information related to the AI / ML model or function to the network device, so as to assist the network device in performing accurate and appropriate life cycle management of the AI / ML model or function, thereby helping to improve the transmission performance of the terminal and the overall performance of the network, and avoiding unnecessary AI / ML computing and storage overhead.

[0330] In the signal transmission-related information applicable to the terminal-side AI / ML model or function, the network device identifier can be the ID of the applicable base station of the terminal-side AI / ML model or function.
[0331] In one implementation, even if the ID of the applicable base station for the terminal-side AI / ML model or function indicated by the terminal is different from the current base station ID, if the current base station determines that the applicable base station indicated by the terminal is similar to the wireless environment of the current base station, it can also determine that the current environment is suitable for activating or using the terminal-side AI / ML model or function.

[0336] B. Global cell ID, which can clearly indicate a cell in the global range.
[0337] C. An ID specially designed for AI / ML. Different physical cells or global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the terminal-side AI / ML model or function has the same or similar applicability or degree of applicability in these cells.
[0338] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0339] The AI / ML model or function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.

[0341] E. Transmission-Reception Point (TRP) ID.
[0342] (2) Reference signal configuration information of the transmitting device.
[0343] Specifically, when a network device sends a signal and a terminal receives or measures the signal, the reference signal configuration information of the transmitting end device may be reference signal (RS) configuration information of the network device when sending the signal.
[0344] The RS configuration information of the network device when sending a signal may include one or more of the following:

[0356] After obtaining the above signal transmission related information, the network device can use this information to manage the terminal-side AI / ML model or function in one or more of the following ways:
[0357] A. Manage through a simple comparison method. For example, only when the base station ID is the same, and / or the sending configuration is the same, and / or the sending antenna related information is the same, decide to activate the terminal-side AI / ML model or function, or switch to the terminal-side AI / ML model or function with matching ID / configuration / antenna.

[0360] For example, the network device can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the terminal based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of the current network device. If the environmental characteristics are found to be similar, even though the base station ID reported by the terminal is different from the base station under the current network device, it is still decided to activate the terminal-side AI / ML model or function.

[0394] B. By extracting the wireless communication environment characteristics represented by the base station ID, receiving configuration, and receiving antenna reported by the terminal, and comparing them with the wireless communication environment characteristics under this network device, when the environmental characteristics are the same / similar, decide to activate the terminal-side AI / ML model or function, or switch to the terminal-side AI / ML model or function with matching ID / configuration / antenna. Environmental characteristics can be obstacle height and density, whether the base station is placed indoors or outdoors, etc.
[0395] For example, the network device can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the terminal based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of the current network device. If the environmental characteristics are found to be similar, even though the base station ID reported by the terminal is different from the base station under the current network device, it is still decided to activate the terminal-side AI / ML model or function.

Compare the reference value of the signal quality reported by the terminal with the typical value of the signal quality under the network equipment (such as the mean, mode, or expected value during network planning). When the difference between the two is less than a certain threshold, decide to activate or switch to the terminal-side AI / ML model or function; otherwise, deactivate the terminal-side AI / ML model or function, or switch to a more appropriate terminal-side AI / ML model or function.
[0408] B. Compare the appropriate range of signal quality reported by the terminal with the typical value of signal quality under the network device. If the typical value of signal quality of the network device is within the appropriate range reported by the terminal, decide to activate or switch to the terminal-side AI / ML model or function; otherwise, deactivate the terminal-side AI / ML model or function, or switch to a more appropriate terminal-side AI / ML model or function.
[0409] C. Compare the appropriate range of signal quality reported by the terminal with the statistical range of signal quality under the network device. If the difference between the two (for example, the sum of the difference between the maximum value and the minimum value) is less than a certain threshold, decide to activate or switch to the terminal-side AI / ML model or function; otherwise, deactivate the terminal-side AI / ML model or function, or switch to a more appropriate terminal-side AI / ML model or function.
[0410] In some embodiments, the distribution characteristic information of the model or function input data may include one or more of the following, with the model input being taken as an example below:
[0411] (1) The reference distribution of the input data to the model or function.
[0412] The reference distribution of the model or function input data can be one of the following predefined distributions: uniform distribution, Gaussian distribution (i.e., normal distribution), truncated Gaussian distribution, exponential distribution, or chi-square distribution. In addition, there can be other predefined distributions for reference, which are not specifically limited here.
[0413] For example, if the data distribution of the model input data is consistent with a certain reference distribution (such as the difference between the statistical distribution curve of the input data and the probability density distribution curve of a predefined distribution is less than a certain threshold value), then the reference distribution can be directly indicated, indicating that the model input data conforms to the reference distribution.
[0414] (2) A value representing the distribution characteristics of the input data to a model or function.
[0415] The characterization value of the distribution characteristics of the model or function input data may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation and variance. In addition, there may be other characterization values, which are not specifically limited here.
[0416] The reference value and / or characteristic value of the distribution characteristic of the model input data may be a special reference value in a certain distribution, such as an exponential value in an exponential distribution.
[0417] Maximum, minimum, mode, median, mean, standard deviation, and variance can be used to indicate the most appropriate range of model input data distribution characteristics, or the range of model input data distribution characteristics that enables the AI / ML model or function to achieve a specific performance indicator.
[0418] For example, when it is impossible to give a reference distribution of the model or function input data, the distribution characteristics of the input data can be described from various aspects through information such as reference value, characteristic value, maximum value, minimum value, etc.
[0419] In some embodiments, the distribution characteristic information of the model or function output data may include one or more of the following, with the output of the model being taken as an example below:
[0420] (1) The reference distribution of model or function output data.
[0421] The reference distribution of the model or function output data can be one of the following predefined distributions: uniform distribution, Gaussian distribution (i.e., normal distribution), truncated Gaussian distribution, exponential distribution, or chi-square distribution. In addition, there can be other predefined distributions for reference, which are not specifically limited here.
[0422] For example, if the data distribution of the model output data is consistent with a certain reference distribution (such as the difference between the statistical distribution curve of the output data and the probability density distribution curve of a predefined distribution is less than a certain threshold value), then the reference distribution can be directly indicated, indicating that the model output data conforms to the reference distribution.
[0423] (2) A value representing the distribution characteristics of the output data of a model or function.
[0424] The characterization value of the distribution characteristics of the model or function output data may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation and variance. In addition, there may be other characterization values, which are not specifically limited here.
[0425] The reference value and / or characteristic value of the distribution characteristic of the model output data may be a special reference value in a certain distribution, such as an exponential value in an exponential distribution.
[0426] The maximum, minimum, mode, median, mean, standard deviation, and variance can be used to indicate the most appropriate range of model output data distribution characteristics, or the range of model output data distribution characteristics that enables the AI / ML model or function to achieve a specific performance indicator.
[0427] For example, when it is impossible to give a reference distribution of the output data of a model or function, the distribution characteristics of the output data can be described from various aspects through information such as reference value, characteristic value, maximum value, minimum value, etc.
[0428] The management method of the AI / ML model or function provided in the embodiment of the present application solves the problem that the input and output distribution characteristics cannot be portrayed as auxiliary information by designing the distribution characteristic information of the model or function-related data as auxiliary information. When the distribution of the input or output data of the model or function is highly consistent with a specific predefined distribution (for example, the difference between the statistical distribution curve of the input or output data and the probability density distribution curve of a predefined distribution is less than a certain threshold value), the terminal can indicate a reference distribution to more accurately indicate the distribution of the input or output data. Moreover, even if the terminal cannot give a reference distribution of the input or output data, it can also describe the distribution characteristics of the input or output data from various aspects through information such as reference values, characteristic values, maximum values, and minimum values, so that the network device can have a quantitative understanding of the distribution of the input or output data of the terminal-side AI / ML model or function, making it possible to report auxiliary information of the data distribution.
[0429] After obtaining the distribution characteristics of the above model or function-related data, the network device can use this information to manage the terminal-side AI / ML model or function in one or more of the following ways:
[0430] A. When the reference distribution of the input (or output) data of the terminal-side AI / ML model or function is highly consistent with the distribution characteristics of the data in the current environment of the network device (for example, the deviation of the probability density distribution curve between the data distribution statistically generated by the network device and the reference distribution reported by the UE is less than a certain threshold value), it is decided to activate or switch to the terminal-side AI / ML model or function, otherwise, the terminal-side AI / ML model or function is deactivated.
[0431] B. When the characteristics of the input (or output) data of the terminal-side AI / ML model or function are highly consistent with the distribution characteristics of the data in the current environment of the network device (for example, the mean of the network device environment is between the maximum and minimum values of the input data of the terminal-side AI / ML model or function, or the mean of the input data of the terminal-side AI / ML model or function is between the maximum and minimum values of the network device environment), it is decided to activate or switch to the terminal-side AI / ML model or function, otherwise, the terminal-side AI / ML model or function is deactivated.
[0432] C. When the reference distribution and / or characteristics of the input or output data of the terminal-side AI / ML model or function match the distribution characteristics of the data in the current environment of the network device, decide to activate or switch to the terminal-side AI / ML model or function, otherwise deactivate the terminal-side AI / ML model or function.
[0433] D. When only one of the reference distribution and / or characteristics of the input or output data of the terminal-side AI / ML model or function matches the distribution characteristics of the data in the current environment of the network device, a decision can be made to activate or switch to the terminal-side AI / ML model or function based on the one of the input data and output data that has a greater impact on performance. Otherwise, the terminal-side AI / ML model or function can be deactivated.
[0434] For example, the input data has a greater impact on performance. When the reference distribution and / or characteristics of the output data of the AI / ML model or function on the terminal side match the distribution characteristics of the data in the current environment of the network device, the AI / ML model or function on the terminal side is deactivated; when the reference distribution and / or characteristics of the input data of the AI / ML model or function on the terminal side match the distribution characteristics of the data in the current environment of the network device, it is decided to activate or switch to the AI / ML model or function on the terminal side.
[0435] In some embodiments, the physical space-related information of the network device includes one or more of the following:
[0436] (1) The area where the network equipment is located.
[0437] Specifically, the area where the network device is located can be one or more of the following:
[0438] A. Area of predefined representation.
[0439] B. Areas divided by longitude and latitude (for example, each X longitude and Y latitude is divided into one area).
[0440] C. Areas divided by administrative means (country, province, city, district, county, township, street, building, etc.).
[0441] (2) The height of the network equipment. For example, the altitude of the network equipment or the height of the network equipment relative to a certain reference horizontal plane.
[0442] (3) Coverage area of network equipment.
[0443] (4) Physical space relationship information between multiple network devices.
[0444] Specifically, the physical space relationship information between multiple network devices may be an average value, a maximum value, and a minimum value of the inter-station distances between the multiple network devices, an overlapping coverage area of the multiple network devices, and the like.
[0445] (5) Reference scenarios for the areas where network devices are located.
[0446] Specifically, the reference scene of the area where the network device is located can be some predefined scenes, such as urban macro cells, urban micro cells, rural cells, and indoor factory cells, etc. The wireless signal propagation characteristics between different predefined scenes are different, such as different large-scale fading, and / or different small-scale channel characteristics, and / or different probabilities that the propagation path is a direct path, etc.
[0447] When the physical space-related information of the network device includes a reference scene of the area where the network device is located, it can indicate that the network device to which the terminal-side AI / ML model or function is applicable and / or the environment in which the corresponding network device is located when collecting the training data set for the terminal-side AI / ML model or function is the same as or similar to the environment of the reference scene.
[0448] The management method of AI / ML models or functions provided in the embodiments of the present application quantitatively characterizes the scenes of the physical space related to the network devices by using methods such as area division, quantitative description of the height of the network devices, quantitative description of the physical relationship between multiple network devices, and definition of reference scenes, thereby solving the problem that "scenes" are difficult to define in a standardized manner in the standards, and making it possible for the terminal to report the network device-related scenes it prefers as auxiliary information for the AI / ML models or functions.
[0449] In some embodiments, the physical space related information of the terminal includes one or more of the following:
[0450] (1) The height of the terminal. For example, the height of the terminal above sea level or the height of the terminal relative to a reference horizontal plane.
[0451] (2) The moving speed of the terminal.
[0452] Specifically, the moving speed of the terminal may be an average moving speed of the terminal within a period of time. The moving speed of the terminal may also be a maximum moving speed of the terminal.
[0453] (3) The orientation of the terminal.
[0454] The management method of AI / ML models or functions provided in the embodiments of the present application quantitatively characterizes terminal-related scenarios through the height, orientation, and moving speed of the terminal, thereby solving the problem that "scenario" is difficult to define in a standardized manner in the standard, and making it possible for the terminal to report its preferred terminal-related scenarios as auxiliary information for the AI / ML model or function.
[0455] After obtaining the above physical space-related information, the network device can use this information to manage the terminal-side AI / ML model or function in one or more of the following ways:
[0456] A. When the physical space scenario of the network device reported by the terminal is the same as or similar to the physical space scenario of the network device, it is decided to activate or switch to the terminal-side AI / ML model or function.
[0457] B. When the terminal physical space scene reported by the terminal is the same as or similar to the physical space scene of the terminal, decide to activate or switch to the terminal-side AI / ML model or function.
[0458] C. When the physical space scene of the network device reported by the terminal is the same as or similar to the physical space scene of the network device, and the terminal physical space scene reported by the terminal is the same as or similar to the physical space scene of the terminal, activate or switch to the terminal-side AI / ML model or function.
[0459] This approach is relatively simple, but may miss opportunities for edge-side AI / ML models or functions to be used.
[0460] D. When the physical space scene of the network device reported by the terminal is the same or similar to the physical space scene of the network device, or the terminal physical space scene reported by the terminal is the same or similar to the physical space scene of the terminal, the network device decides whether to activate or switch to the terminal-side AI / ML model or function based on the impact of the generalization of the AI / ML model or function in the physical space of the network device and the physical space of the terminal.
[0461] For example, the time domain prediction of the Channel State Information (CSI) based on the AI / ML model has poor generalization to UE speed (i.e., the best AI / ML performance can only be obtained when the speed matches), but has good generalization to the physical space of network devices (i.e., the physical space differences of network devices have little impact on AI / ML performance). The network device can decide to activate the AI / ML model when the terminal speed matches (although the physical space of the network device does not match).
[0462] This method is relatively complex and requires network equipment to determine in which scenarios / configurations / conditions the AI / ML model or function has better generalization performance, but it may maximize the terminal-side AI / ML model or function and maximize network performance.
[0463] In some embodiments, the training data set identifier is a training data set identifier determined based on at least one of a predefined rule, a high-layer signaling configuration, and operation administration and maintenance (OAM) pre-configuration information.
[0464] Specifically, the training data set identifier may be determined based on at least one of a predefined rule, a high-level signaling configuration, and OAM pre-configuration information.
[0465] In one implementation, when determining the identification of a training data set based on a predefined rule, it may be agreed in a manner specified by a protocol that a training data set that meets a specific scenario / configuration / condition has a specific identification.
[0466] For example, the ID of a dataset collected in an urban scene is 0, the ID of a dataset collected in a suburban scene is 1, the ID of a dataset collected in an indoor factory is 2, the ID of a mixed dataset collected in an urban + suburban scene is 3, and so on.
[0467] In addition, the training data set identifier can also be determined based on scene-related information that affects wireless communication performance, such as weather information in outdoor scenes. Specifically, the ID of data collected in urban areas + good weather is 11, the ID of data collected in urban areas + rainy weather is 12, the ID of data collected in suburban areas + good weather is 21, and so on.
[0468] In one implementation, when determining the training data set identifier based on high-level signaling configuration, the training data set identifier can be determined based on Radio Resource Control Protocol (RRC) signaling, Long-Term-Evolution Positioning Protocol (LPP) signaling, signaling from the core network, or signaling from the application layer.
[0469] In one implementation, when determining the training data set identifier based on OAM pre-configuration information, the terminal manufacturer and the network equipment manufacturer or operator may agree to use a specific data set ID to represent a specific scenario / configuration / condition, and determine the training data set ID manually.
[0470] In some embodiments, the training data set identifier includes at least one bit field, each bit field is used to indicate one of the following information: signal sending related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information.
[0471] Specifically, the training data set identifier may be determined based on one or more of the information related to signal transmission, the information related to signal reception, the information related to signal quality, the distribution characteristic information of model or function related data, and the information related to physical space. The determined training data set identifier may include at least one bit field, each bit field being used to indicate one of the information related to signal transmission, the information related to signal reception, the information related to signal quality, the distribution characteristic information of model or function related data, and the information related to physical space.
[0472] In one implementation, the training data set identifier includes M bit fields, corresponding to M information in signal transmission related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information, and each bit field occupies n1, n2, ...n respectively. M bits, and these M bits form the training data set identifier. The length of the training data set identifier is greater than or equal to n1+n2+…+n M bits, and the value of each bit field corresponds to candidate information in a corresponding indication field.
[0473] For example, five pieces of information including signal transmission related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information correspond to five bit fields respectively, and each bit field occupies n1, n2, ... n5 bits respectively. The five bit fields constitute the training data set identifier, and the identifier length N = n1 + n2 + ... + n M .
[0474] The SNR range in the signal quality related information is divided into 7 regions, so n3=ceil(log2(7))=3 bits are used to represent the 7 regions, and the value of the 3 bits is {000, 001, ...101, 110}, which is one of the 7 SNR regions.
[0475] In some embodiments, the training data set identifier includes K bits, and the K bits are used to indicate at most 2 K One of the information combinations; K is an integer greater than or equal to 1;
[0476] The information combination is different candidate combinations of L information among information related to signal transmission, information related to signal reception, information related to signal quality, distribution characteristic information of model or function related data, and information related to physical space;
[0477] The number of different candidate combinations of L information is less than or equal to 2 K , L is an integer greater than or equal to 1.
[0478] Specifically, the training data set identifier can be determined based on different candidate combinations of L information including information related to signal transmission, information related to signal reception, information related to signal quality, distribution characteristic information of model or function related data, and information related to physical space.
[0479] According to the number of different candidate combinations of L information, the number of bits K contained in the training data set identifier can be determined. K The number of different candidate combinations greater than or equal to L information.
[0480] For example, the training data set identifier is determined according to three pieces of information {network device ID, terminal height, SINR} among the signal transmission related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information, and there are 60 possible candidate combinations of {network device ID, terminal height, SINR} (3 network device IDs, 4 terminal heights, 5 SINRs), then K=6 (2 6 =64) bits of training data set identifier represents these 60 combinations. The values of the training data set identifier are {000000, 000001, ..., 111011}, and each value represents one of the 60 combinations.
[0481] In some embodiments, the training data set identifier includes multiple sub-identifiers, each sub-identifier is used to indicate one of the following information: signal sending related information, signal receiving related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information.
[0482] Specifically, the training data set identifier may also include multiple sub-identifiers, each of which may be used to indicate one of the following information: signal sending related information, signal receiving related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information.
[0483] For example, the sub-identifier of the training data set is determined according to the three information {network device ID, terminal height, SINR}, and there are three sub-identifiers. The value of the first sub-identifier identifies the network device ID, the value of the second sub-identifier indicates the terminal height, and the value of the third sub-identifier indicates the SINR.
[0484] In some embodiments, the multiple sub-identifiers included in the training data set identifier may also be determined according to any one of the following methods:
[0485] (1) Determine multiple sub-identifiers included in the training data set identifier based on predefined rules.
[0486] For example, it can be agreed in a manner specified by the protocol that a training dataset that meets a specific scenario / configuration / condition has a specific sub-identifier.
[0487] (2) Determine multiple sub-identifiers included in the training data set identifier based on the high-level signaling configuration.
[0488] For example, the multiple sub-identifiers included in the training data set identifier may be determined according to RRC signaling, LPP signaling, signaling from a core network, or signaling from an application layer.
[0489] (3) Determine the training data set identifier based on the OAM pre-configuration information.
[0490] For example, the terminal manufacturer and the network equipment manufacturer or operator may agree to use a specific dataset sub-ID to represent a specific scenario / configuration / condition, and determine the training dataset sub-ID manually.
[0491] The management method of the AI / ML model or function provided in the embodiment of the present application establishes a one-to-one mapping relationship between the auxiliary information and the training data set identifier (dataset ID), so that the dataset ID can carry the auxiliary information, or through advance agreement between the terminal and the network device, assisted by manual configuration or high-level signaling configuration, the terminal and the network device can align the applicable scenarios / configurations / conditions of the AI / ML model or function according to the dataset ID reported by the terminal, so that the dataset ID can characterize the characteristics of the training data in a quantitative expression, so it becomes possible for the terminal to report the dataset ID corresponding to its own AI / ML model or function as auxiliary information.
[0492] The network device can determine the match between the characteristics of the training data set of the terminal's AI / ML model or function and the characteristics of the cell based on the training data set identifier reported by the terminal, thereby reasonably managing the AI / ML model or function on the terminal side.
[0493] After obtaining the training dataset identifier, the network device can use this information to manage the terminal-side AI / ML model or function in one or more of the following ways:
[0494] A. Determine the scenario / configuration / condition of the current network device based on the dataset ID, and compare the scenario / configuration / condition corresponding to the training data of the terminal-side AI / ML model or function. When some or all of the scenarios / configurations / conditions match, determine that the terminal-side AI / ML model or function can be activated.
[0495] B. Determine whether the network device itself participates in the data collection of the dataset corresponding to the dataset ID. When the network device itself participates in the data collection of the dataset corresponding to the dataset ID, determine that the terminal-side AI / ML model or function can be activated.
[0496] C. The network device itself saves or maintains relevant information about "dataset IDs suitable for AI / ML models or functions used on the current network device", such as a dataset ID list or set (but the network device itself does not necessarily participate in the data collection corresponding to each dataset). The list or set can be manually configured or come from high-level information. When the dataset ID reported by the terminal is in the list or set of dataset IDs saved or maintained by the network device, it is determined that the terminal-side AI / ML model or function can be activated.
[0497] Figure 2 The second flowchart of the method for managing the AI / ML model or function provided in the embodiment of the present application is applied to a network device, such as Figure 2 As shown, the method comprises the following steps:
[0498] Step 200: receiving auxiliary information related to the AI / ML model or function sent by the terminal, where the auxiliary information includes first information applicable to the AI / ML model or function and / or first information corresponding to a training data set of the AI / ML model or function, and the first information is used for the network device to manage the AI / ML model or function.
[0499] Specifically, a unilateral model on the terminal side or the terminal side part of a bilateral model can be deployed in the terminal. The model deployed in the terminal can be trained and generated by the terminal manufacturer, chip manufacturer or third-party service provider. Network equipment (such as a base station) can be the LCM manager of the AI / ML model or function on the terminal side.
[0500] In order to ensure the performance of the AI / ML model or function on the terminal side in the current network, the terminal can send auxiliary information related to the AI / ML model or function on the terminal side to the network device. After receiving the auxiliary information, the network device can use the auxiliary information to manage the AI / ML model or function on the terminal side.
[0501] The AI / ML model or function management method provided in the embodiment of the present application is that the network device performs accurate and appropriate lifecycle management of the AI / ML model or function by receiving auxiliary information related to the AI / ML model or function sent by the terminal, which helps to improve the transmission performance of the terminal and the overall performance of the network and avoid unnecessary AI / ML computing and storage overhead.

[0544] The methods provided in the embodiments of the present application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.
[0545] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.
[0546] Example 1: Applicable scenarios for management methods of AI / ML models or functions.

Information related to the NW transmitting antenna, such as one or more of the following: the NW Tx transmitting channel (panel), antenna array pattern, vertical angle of the transmitting beam, horizontal angle of the transmitting beam, transmitting power, relative power of each angle between multiple transmitting beams, etc.
[0565] For UE transmission, NW reception or measurement, the information related to signal transmission may include one or more of the following:
[0566] a. Base station ID.
[0567] The base station ID indicates the ID of the base station applicable to the UE's AI / ML model or function. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the wireless environment of the base station indicated by the UE is similar to that of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:

[0571] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0572] The AI / ML model / function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.
[0573] a4. ID that can be determined by other methods, such as the cell ID determined by the PLMN number and the cellIdentity specified in the PLMN.
[0574] a5. TRP ID.
[0575] b. UE sends configuration related information.

Manage through a simple comparison method, for example, only when the ID is the same, and / or the sending configuration is the same, and / or the sending antenna related information is the same, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function with matching ID / configuration / antenna.
[0580] This approach is simple to implement, but may miss opportunities for the UE's AI / ML models / functions to be utilized.
[0581] B. By extracting the wireless communication environment characteristics represented by the base station ID, transmission configuration, and transmission antenna reported by the UE, and comparing them with the wireless communication environment characteristics under this NW, when the environmental characteristics are the same / similar, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function that matches the ID / configuration / antenna. Environmental characteristics can be, for example, obstacle height and density, whether the base station is placed indoors or outdoors, etc.
[0582] For example, NW can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the UE, based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of this NW. If the environmental characteristics are found to be similar, even though the base station ID reported by the UE is different from the base station under this NW, it is still decided to activate the UE's AI / ML model or function.
[0583] This method is more complicated to implement, but it can maximize the reasoning capabilities of the UE's AI / ML models / functions and improve network performance.
[0584] (2) Information related to the signal reception corresponding to the AI / ML model or function.

[0600] The base station ID indicates the ID of the base station applicable to the UE's AI / ML model or function. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the wireless environment of the base station indicated by the UE is similar to that of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:
[0601] a1. Physical cell ID, which is carried and indicated by SSB and represents the ID of the cell visible at the physical layer.
[0602] a2. Global cell ID, which can clearly indicate a cell in the global range.
[0603] a3. ID specially designed for AI / ML. Different physical cells / global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the AI / ML model or function of the UE has the same or similar applicability or degree of applicability in these cells.
[0604] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0605] The AI / ML model / function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.

[0609] b1. RS configuration information, including one or more of the following: signal type (such as SRS, etc.), number, time domain resources, frequency domain resources, number of ports, sequence, RS resource ID, RS resource set ID, RS ID, etc.
[0610] b2. Information related to the NW receiving antenna, such as one or more of the following: NW Rx receiving channel (panel), antenna array pattern, vertical angle of receiving beam, horizontal angle of receiving beam, receiving power, relative power of each angle between multiple receiving beams, etc.
[0611] This information can indicate the NW side receiving configuration or the UE side receiving configuration suitable for the AI / ML model or function of the UE. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0612] A. Manage through a simple comparison method, for example, only when the ID is the same, and / or the receiving configuration is the same, and / or the receiving antenna related information is the same, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function with matching ID / configuration / antenna.
[0613] This approach is simple to implement, but may miss opportunities for the UE's AI / ML models / functions to be utilized.
[0614] B. By extracting the wireless communication environment characteristics represented by the base station ID, receiving configuration, and receiving antenna reported by the UE, and comparing them with the wireless communication environment characteristics under this NW, when the environmental characteristics are the same / similar, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function that matches the ID / configuration / antenna. Environmental characteristics can be, for example, obstacle height and density, whether the base station is placed indoors or outdoors, etc.
[0615] For example, NW can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the UE, based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of this NW. If the environmental characteristics are found to be similar, even though the base station ID reported by the UE is different from the base station under this NW, it is still decided to activate the UE's AI / ML model or function.
[0616] This method is more complicated to implement, but it can maximize the reasoning capabilities of the UE's AI / ML models / functions and improve network performance.
[0617] (3) Information related to the signal quality corresponding to the AI / ML model or function.
[0618] a. Information related to the signal quality metric.
[0619] a1. The signal quality metric may be one or more of SNR, SINR, RSRP, and RSRQ. In addition, there may be other signal quality metric methods, which are not specifically limited here.
[0620] a2. The relevant information may be one or more of the following: reference value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characteristic values of signal quality, which are not specifically limited here.
[0621] The reference value may be, for example, the most appropriate value, such as the most appropriate SINR, the most appropriate RSRP, or a value that enables the AI / ML model or function to achieve a specific performance indicator.
[0622] The maximum, minimum, mode, median, mean, standard deviation, and variance are used to indicate the most suitable range, such as the most suitable SINR range, the most suitable RSRQ range, or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0623] If a plurality of signal quality metrics are indicated, relevant information (reference value, maximum value, etc.) of each signal quality metric may be indicated separately.
[0624] This information can indicate the signal quality of the AI / ML model or function suitable for the UE. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more models or functions as follows:
[0625] A. Compare the reference value of the signal quality reported by the UE with the typical value of the signal quality under the NW (such as the mean, mode, or expected value during network planning). When the difference between the two is less than a certain threshold, decide to activate / switch to the AI / ML model or function of the UE. Otherwise, deactivate the AI / ML model or function of the UE, or switch to a more suitable UE AI / ML model or function.
[0626] B. Compare the appropriate range of signal quality reported by the UE with the typical value of signal quality under the NW. If the typical value of signal quality of the NW is within the appropriate range reported by the UE, decide to activate / switch to the AI / ML model or function of the UE; otherwise, deactivate the AI / ML model or function of the UE, or switch to a more appropriate UE AI / ML model or function.
[0627] C. Compare the appropriate range of signal quality reported by the UE with the statistical range of signal quality under the NW. If the difference between the two (such as the sum of the difference between the maximum value and the minimum value) is less than a certain threshold, decide to activate / switch to the AI / ML model or function of the UE. Otherwise, deactivate the AI / ML model or function of the UE, or switch to a more appropriate UE AI / ML model or function.
[0628] (4) Distribution characteristic information of the training data corresponding to the AI / ML model or function.
[0629] a. The distribution characteristic information of the input data includes one or more of the following:
[0630] a1. The reference distribution of the input data may be one of the following predefined distributions: uniform distribution, Gaussian distribution (ie, normal distribution), truncated Gaussian distribution, exponential distribution, chi-square distribution, etc. In addition, there may be other predefined distributions for reference, which are not specifically limited here.
[0631] a2. Information related to the distribution characteristics of the input data, which may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characterization values, which are not specifically limited here.
[0632] Reference values and characteristic values can be special reference values in a certain distribution, such as the exponential value in an exponential distribution.
[0633] Maximum, minimum, mode, median, mean, standard deviation, variance, etc. are used to indicate the most appropriate range or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0634] b. The distribution characteristic information of the output data includes one or more of the following:
[0635] b1. The reference distribution of the output data may be one of the following predefined distributions: uniform distribution, Gaussian distribution (ie, normal distribution), truncated Gaussian distribution, exponential distribution, chi-square distribution, etc. In addition, there may be other predefined distributions for reference, which are not specifically limited here.
[0636] b2. Information related to the distribution characteristics of the output data, which may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characterization values, which are not specifically limited here.
[0637] Reference values and characteristic values can be special reference values in a certain distribution, such as the exponential value in an exponential distribution.
[0638] Maximum, minimum, mode, median, mean, standard deviation, variance, etc. are used to indicate the most appropriate range or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0639] It should be emphasized that the design of the above-mentioned auxiliary information solves the problem that the input distribution characteristics cannot be characterized as auxiliary information. When the distribution of the input data of the model or function is highly consistent with a specific predefined distribution (such as the difference between the statistical distribution curve of the input data and the probability density distribution curve of a predefined distribution is less than a certain threshold value), the UE can indicate a reference distribution to more accurately indicate the distribution of the input data. Moreover, even if the UE cannot give a reference distribution, it can describe the distribution characteristics of the input data from various aspects through reference values, characteristic values, maximum values, minimum values and other information, so that the NW can have a quantitative understanding of the distribution of the input or output data corresponding to the UE model / function, making it possible to report auxiliary information on the data distribution.
[0640] This information can indicate the distribution characteristics of the input and / or output of the AI / ML model or function suitable for the UE. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0641] A. When the reference distribution of the input (or output) data of the UE model or function is highly consistent with the distribution characteristics of the data in the current environment of the NW (for example, the deviation of the probability density distribution curve between the data distribution statistically obtained by the NW and the reference distribution reported by the UE is less than a certain threshold), it is decided to activate / switch to the AI / ML model or function of the UE, otherwise the AI / ML model or function of the UE is deactivated.
[0642] B. When the data characteristics of the input (or output) of the UE model or function are highly consistent with the distribution characteristics of the data in the current NW environment (for example, the mean of the NW environment is between the maximum and minimum values of the UE's input data, or the mean of the UE's input data is between the maximum and minimum values of the NW environment), it is decided to activate / switch to the UE's AI / ML model or function, otherwise, deactivate the UE's AI / ML model or function.
[0643] C. Based on management mode A or B, when the input data reference distribution and the output data reference distribution of the UE match, decide to activate / switch to the AI / ML model or function of the UE, otherwise deactivate the AI / ML model or function of the UE.
[0644] D. Based on management mode A or B, when only one of the input data reference distribution or the output data reference distribution of the UE can match, decide to activate / switch to the AI / ML model or function of the UE according to the one that has a greater impact on performance, otherwise deactivate the AI / ML model or function of the UE.
[0645] (5) Information related to the physical space corresponding to the AI / ML model or function.
[0646] a. Information related to the physical space of the base station.
[0647] a1. The area where the base station is located can be one or more of the following:
[0648] Areas of predefined representation;
[0649] Areas divided by longitude and latitude (e.g., each X longitude and Y latitude is divided into one area);
[0650] An area divided by administrative means (country, province, city, district, county, township, street, building, etc.).
[0651] a2. The height of the base station.
[0652] a3. The physical space related information between multiple base stations may be one or more of the following:
[0653] The average, maximum, and minimum values of the inter-station distances of multiple stations;
[0654] The coverage area of the plurality of stations (the coverage area of each of the plurality of stations and / or the joint coverage area of the plurality of stations).
[0655] a3. Reference scene of the area where NW is located.
[0656] The reference scenario may be some predefined scenarios, such as urban macrocell, urban microcell, rural cell, indoor factory cell. The wireless signal propagation characteristics between different predefined scenarios are different, such as different large-scale fading, and / or different small-scale channel characteristics, and / or different probabilities that the propagation path is a direct path, etc.
[0657] If the information indicates a reference scene, it means that the environment where the NW is located is the same as or similar to the environment of the reference scene.
[0658] It should be emphasized that in the above-mentioned auxiliary information, the scenes of the physical space related to the base station are quantitatively characterized by using methods such as area division, quantitative description of the height of the base station, quantitative description of the physical relationship between multiple base stations, and definition of reference scenes. This solves the problem that "scenes" are difficult to define in a standardized manner in the standard, making it possible for the UE to report its preferred NW-related scenes as auxiliary information for AI / ML models or functions.
[0659] b. Information related to the physical space of the UE.
[0660] b1. UE height.
[0661] b2. Moving speed of the UE. The moving speed may be an average value and / or a maximum value.
[0662] b3. UE's orientation.
[0663] It should be emphasized that the above-mentioned auxiliary information quantitatively describes the UE-related scenarios by using the height, direction and moving speed of the UE, which solves the problem that "scenario" is difficult to define in a standardized way in the standard. It makes it possible for the UE to report its preferred UE-related scenarios as auxiliary information for AI / ML models or functions.
[0664] This information can indicate the state of the physical space suitable for the AI / ML model or function of the UE. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more models / functions as follows:
[0665] A. When the NW physical space scene corresponding to the AI / ML model or function reported by the UE is the same / similar to the physical space scene of this NW, decide to activate / switch to the AI / ML model or function of the UE.
[0666] B. When the UE physical space scene corresponding to the AI / ML model or function reported by the UE is the same / similar to the physical space scene of the UE, decide to activate / switch to the AI / ML model or function of the UE.
[0667] C. Based on management methods A and B, the AI / ML model or function of the UE is activated / switched to when the NW physical space scene and the UE physical space scene corresponding to the AI / ML model or function reported by the UE match / match the physical space scene of the NW and the physical space scene of the UE;
[0668] This approach is relatively simple, but may miss opportunities for UE’s AI / ML models / functions to come into play.
[0669] D. Based on management methods A and B, if the NW physical space scenario and the UE physical space scenario corresponding to the AI / ML model or function reported by the UE only match / match one of the NW physical space scenario and the UE physical space scenario, the NW also decides whether to activate / switch to the UE's AI / ML model or function based on the impact of the generalization of the AI / ML model or function in the NW physical space and the UE physical space. For example, the CSI time domain prediction based on the AI / ML model has poor generalization to the UE speed (that is, the best AI / ML performance can only be obtained when the speed matches), but has good generalization to the NW physical space (that is, the physical space difference of the NW has little impact on the AI / ML performance), then the NW can decide to activate the AI / ML model when the UE speed matches (although the NW physical space does not match).
[0670] This method is relatively complex and requires the NW to determine in which scenarios / configurations / conditions the AI / ML model or function has good generalization performance, but it may maximize the UE's AI / ML model or function and maximize network performance.
[0671] The above auxiliary information is used to indicate the applicable scenarios, and / or applicable configurations, and / or applicable conditions of the AI / ML model or function on the UE side.
[0672] On the one hand, each AI / ML model or function may correspond to one piece of auxiliary information, or to multiple pieces of auxiliary information. Multiple pieces of auxiliary information indicate that the AI / ML model or function is applicable to multiple scenarios / configurations / conditions.
[0673] On the other hand, if the UE has multiple AI / ML models or multiple AI / ML functionality, the UE may indicate the auxiliary information corresponding to each AI / ML model or each AI / ML functionality, or divide the AI / ML model or AI / ML functionality into several sets and indicate the auxiliary information corresponding to each model set or functionality set.
[0674] After receiving the auxiliary information sent by the UE, the NW can reasonably manage the AI / ML model or function on the UE side based on the auxiliary information, for example:
[0675] A. Compare one or more applicable scenarios / configurations / conditions corresponding to the AI / ML model / function indicated / suggested by the UE with the scenarios / configurations / conditions of the current NW. When all or part of the scenarios match, activate the AI / ML model / function of the UE.
[0676] B. Compare one or more applicable scenarios / configurations / conditions corresponding to the AI / ML model / function indicated / suggested by the UE with the scenarios / configurations / conditions of the current NW. When the scenarios / configurations / conditions that "significantly affect generalization performance" can be matched, activate the AI / ML model / function of the UE; otherwise, deactivate the AI / ML model function of the UE.
[0677] C. Compare one or more applicable scenarios / configurations / conditions corresponding to multiple AI / ML models indicated / suggested by the UE, select the AI / ML model that best matches the current scenario / configuration / condition for activation, or switch to the AI / ML model that best matches the current configuration.
[0678] Example 3: The UE sends auxiliary information related to the training dataset of the AI / ML model or function on the UE side to the NW to assist the NW in reasonably managing the AI / ML model or function on the UE side.
[0679] In Example 2, the auxiliary information sent by the UE to the NW is used to indicate the applicable scenarios / configurations / conditions of the AI / ML model or function on the UE side, which is equivalent to the UE training the AI / ML model based on the training data collected on the UE side as the training dataset, and recommending the applicable scenarios / configurations / conditions of its own AI / ML model or function to the NW based on the collected training data.
[0680] In this example, the auxiliary information sent by the UE to the NW directly indicates the information related to the training data set corresponding to the AI / ML model or function, which is equivalent to that the UE does not directly suggest the applicable scenarios / configurations / conditions of its own AI / ML model or function, but leaves it to the NW for judgment. The NW can decide how to manage the UE's AI / ML model or function based on the scenarios / configurations / conditions when the training data set is collected and the scenarios / configurations / conditions of the current cell.
[0681] The auxiliary information related to the training data set of one or more AI / ML models or functions on the UE side sent by the UE to the NW may include one or more of the following:
[0682] (1) Information related to the signal transmission of training data corresponding to the AI / ML model or function.
[0683] For NW transmission, UE reception or measurement, the information related to signal transmission may include one or more of the following:
[0684] a. Base station ID.
[0685] The base station ID indicates the ID of the base station from which the training data of the UE's AI / ML model or function is collected. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the base station from which the training data indicated by the UE is collected is similar to the wireless environment of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:
[0686] a1. Physical cell ID, which is carried and indicated by SSB and represents the ID of the cell visible at the physical layer.
[0687] a2. Global cell ID, which can clearly indicate a cell in the global range.
[0688] a3. ID specially designed for AI / ML. Different physical cells / global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the AI / ML model or function of the UE has the same or similar applicability or degree of applicability in these cells.
[0689] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0690] The AI / ML model / function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.
[0691] a4. ID that can be determined by other methods, such as the cell ID determined by the PLMN number and the cellIdentity specified in the PLMN.
[0692] a5. TRP ID.
[0693] b. NW sends configuration related information.
[0694] b1. RS configuration information, one or more of the following: signal type (e.g. CSI-RS, SSB, PRS, etc.), number, time domain resources, frequency domain resources, number of ports, sequence, RS resource ID, RS resource set ID, RS ID, etc.

Information related to the NW transmitting antenna, such as one or more of the following: the NW Tx transmitting channel (panel), antenna array pattern, vertical angle of the transmitting beam, horizontal angle of the transmitting beam, transmitting power, relative power of each angle between multiple transmitting beams, etc.
[0696] For UE transmission, NW reception or measurement, the information related to signal transmission may include one or more of the following:
[0697] a. Base station ID.
[0698] The base station ID indicates the ID of the base station from which the training data of the UE's AI / ML model or function is collected. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the base station from which the training data indicated by the UE is collected is similar to the wireless environment of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:
[0699] a1. Physical cell ID, which is carried and indicated by SSB and represents the ID of the cell visible at the physical layer.
[0700] a2. Global cell ID, which can clearly indicate a cell in the global range.
[0701] a3. ID specially designed for AI / ML. Different physical cells / global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the AI / ML model or function of the UE has the same or similar applicability or degree of applicability in these cells.

[0706] b. UE sends configuration related information.
[0707] b1. RS configuration information, including one or more of the following: signal type (such as SRS, etc.), number, time domain resources, frequency domain resources, number of ports, sequence, RS resource ID, RS resource set ID, RS ID, etc.
[0708] b2. Information related to the UE transmit antenna, such as one or more of the following: the number of UE Tx antennas, antenna array pattern, angle information of the transmit beam, usage status of the transmit beam, etc.
[0709] This information can indicate the NW-side sending configuration or the UE-side sending configuration when collecting training data for the UE's AI / ML model or function. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0710] A. Manage through a simple comparison method, for example, only when the ID is the same, and / or the sending configuration is the same, and / or the sending antenna related information is the same, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function with matching ID / configuration / antenna.
[0711] This approach is simple to implement, but may miss opportunities for the UE's AI / ML models / functions to be utilized.
[0712] B. By extracting the wireless communication environment characteristics represented by the base station ID, transmission configuration, and transmission antenna reported by the UE, and comparing them with the wireless communication environment characteristics under this NW, when the environmental characteristics are the same / similar, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function that matches the ID / configuration / antenna. Environmental characteristics can be, for example, obstacle height and density, whether the base station is placed indoors or outdoors, etc.
[0713] For example, NW can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the UE, based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of this NW. If the environmental characteristics are found to be similar, even though the base station ID reported by the UE is different from the base station under this NW, it is still decided to activate the UE's AI / ML model or function.
[0714] This method is more complicated to implement, but it can maximize the reasoning capabilities of the UE's AI / ML models / functions and improve network performance.
[0715] (2) Information related to the signal reception corresponding to the AI / ML model or function.
[0716] For NW transmission, UE reception or measurement, the information related to signal transmission may include one or more of the following:
[0717] a. Base station ID.
[0718] The base station ID indicates the ID of the base station from which the training data of the UE's AI / ML model or function is collected. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the base station from which the training data indicated by the UE is collected is similar to the wireless environment of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:
[0719] a1. Physical cell ID, which is carried and indicated by SSB and represents the ID of the cell visible at the physical layer.
[0720] a2. Global cell ID, which can clearly indicate a cell in the global range.
[0721] a3. ID specially designed for AI / ML. Different physical cells / global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the AI / ML model or function of the UE has the same or similar applicability or degree of applicability in these cells.
[0722] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0723] The AI / ML model / function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.
[0724] a4. ID that can be determined by other methods, such as the cell ID determined by the PLMN number and the cellIdentity specified in the PLMN.
[0725] a5. TRP ID.
[0726] b. The UE receives configuration related information.
[0727] b1. RS configuration information, one or more of the following: signal type (e.g. CSI-RS, SSB, PRS, etc.), number, time domain resources, frequency domain resources, number of ports, sequence, RS resource ID, RS resource set ID, RS ID, etc.
[0728] b2. UE receive antenna related information, such as one or more of the following: the number of UE Rx antennas, antenna array pattern, receive beam angle information, receive beam usage status, etc.
[0729] For UE transmission, NW reception or measurement, the information related to signal transmission may include one or more of the following:
[0730] a. Base station ID.
[0731] The base station ID indicates the ID of the base station from which the training data of the UE's AI / ML model or function is collected. Even if the base station ID indicated by the UE is different from the current base station ID of the NW, if the NW determines that the base station from which the training data indicated by the UE is collected is similar to the wireless environment of the current base station, it can also determine that the current environment is suitable for activating or using the UE's AI / ML model or function. The base station ID can be one or more of the following:
[0732] a1. Physical cell ID, which is carried and indicated by SSB and represents the ID of the cell visible at the physical layer.
[0733] a2. Global cell ID, which can clearly indicate a cell in the global range.
[0734] a3. ID specially designed for AI / ML. Different physical cells / global cells can use the same AI / ML cell ID. The same AI / ML cell ID indicates that the AI / ML model or function of the UE has the same or similar applicability or degree of applicability in these cells.
[0735] The training data collected from cells with the same AI / ML cell ID have similar distribution characteristics.
[0736] The AI / ML model / function trained with the training data collected from any one or more cells having the same AI / ML cell ID is suitable for use in any one of the cells having the same AI / ML cell ID.
[0737] a4. ID that can be determined by other methods, such as the cell ID determined by the PLMN number and the cellIdentity specified in the PLMN.
[0738] a5. TRP ID.
[0739] b. NW receives configuration related information.
[0740] b1. RS configuration information, including one or more of the following: signal type (such as SRS, etc.), number, time domain resources, frequency domain resources, number of ports, sequence, RS resource ID, RS resource set ID, RS ID, etc.
[0741] b2. Information related to the NW receiving antenna, such as one or more of the following: NW Rx receiving channel (panel), antenna array pattern, vertical angle of receiving beam, horizontal angle of receiving beam, receiving power, relative power of each angle between multiple receiving beams, etc.
[0742] This information can indicate the NW side receiving configuration or the UE side receiving configuration when collecting training data for the UE's AI / ML model or function. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0743] A. Manage through a simple comparison method, for example, only when the ID is the same, and / or the receiving configuration is the same, and / or the receiving antenna related information is the same, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function with matching ID / configuration / antenna.
[0744] This approach is simple to implement, but may miss opportunities for the UE's AI / ML models / functions to be utilized.
[0745] B. By extracting the wireless communication environment characteristics represented by the base station ID, receiving configuration, and receiving antenna reported by the UE, and comparing them with the wireless communication environment characteristics under this NW, when the environmental characteristics are the same / similar, decide to activate the UE's AI / ML model or function, or switch to the AI / ML model or function that matches the ID / configuration / antenna. Environmental characteristics can be, for example, obstacle height and density, whether the base station is placed indoors or outdoors, etc.
[0746] For example, NW can determine the wireless communication environment characteristics corresponding to the base station through the base station ID reported by the UE, based on the location and map information of the reported base station, and compare them with the wireless communication environment characteristics of this NW. If the environmental characteristics are found to be similar, even though the base station ID reported by the UE is different from the base station under this NW, it is still decided to activate the UE's AI / ML model or function.
[0747] This method is more complicated to implement, but it can maximize the reasoning capabilities of the UE's AI / ML models / functions and improve network performance.
[0748] (3) Information related to the signal quality of the training data corresponding to the AI / ML model or function.
[0749] a. Information related to the signal quality metric.
[0750] a1. The signal quality metric may be one or more of SNR, SINR, RSRP, and RSRQ. In addition, there may be other signal quality metric methods, which are not specifically limited here.
[0751] a2. The relevant information may be one or more of the following: reference value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characteristic values of signal quality, which are not specifically limited here.
[0752] The reference value may be, for example, the most appropriate value, such as the most appropriate SINR, the most appropriate RSRP, or a value that enables the AI / ML model or function to achieve a specific performance indicator.
[0753] The maximum, minimum, mode, median, mean, standard deviation, and variance are used to indicate the most suitable range, such as the most suitable SINR range, the most suitable RSRQ range, or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0754] If a plurality of signal quality metrics are indicated, relevant information (reference value, maximum value, etc.) of each signal quality metric may be indicated separately.
[0755] This information can indicate the signal quality of the UE's AI / ML model or function when the training data set is collected. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more models or functions as follows:
[0756] A. Compare the reference value of the signal quality reported by the UE with the typical value of the signal quality under the NW (such as the mean, mode, or expected value during network planning). When the difference between the two is less than a certain threshold, decide to activate / switch to the AI / ML model or function of the UE. Otherwise, deactivate the AI / ML model or function of the UE, or switch to a more suitable UE AI / ML model or function.
[0757] B. Compare the appropriate range of signal quality reported by the UE with the typical value of signal quality under the NW. If the typical value of signal quality of the NW is within the appropriate range reported by the UE, decide to activate / switch to the AI / ML model or function of the UE; otherwise, deactivate the AI / ML model or function of the UE, or switch to a more appropriate UE AI / ML model or function.
[0758] C. Compare the appropriate range of signal quality reported by the UE with the statistical range of signal quality under the NW. If the difference between the two (such as the sum of the difference between the maximum value and the minimum value) is less than a certain threshold, decide to activate / switch to the AI / ML model or function of the UE. Otherwise, deactivate the AI / ML model or function of the UE, or switch to a more appropriate UE AI / ML model or function.
[0759] (4) Distribution characteristic information of the training data corresponding to the AI / ML model or function.
[0760] a. The distribution characteristic information of the input data includes one or more of the following:
[0761] a1. The reference distribution of the input data may be one of the following predefined distributions: uniform distribution, Gaussian distribution (ie, normal distribution), truncated Gaussian distribution, exponential distribution, chi-square distribution, etc. In addition, there may be other predefined distributions for reference, which are not specifically limited here.
[0762] a2. Information related to the distribution characteristics of the input data, which may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characterization values, which are not specifically limited here.
[0763] Reference values and characteristic values can be special reference values in a certain distribution, such as the exponential value in an exponential distribution.
[0764] Maximum, minimum, mode, median, mean, standard deviation, variance, etc. are used to indicate the most appropriate range or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0765] b. The distribution characteristic information of the output data includes one or more of the following:
[0766] a1. The reference distribution of the output data may be one of the following predefined distributions: uniform distribution, Gaussian distribution (ie, normal distribution), truncated Gaussian distribution, exponential distribution, chi-square distribution, etc. In addition, there may be other predefined distributions for reference, which are not specifically limited here.
[0767] a2. Information related to the distribution characteristics of the output data, which may be one or more of the following: reference value, characteristic value, maximum value, minimum value, mode, median, mean, standard deviation, variance, etc. In addition, there may be other characterization values, which are not specifically limited here.
[0768] Reference values and characteristic values can be special reference values in a certain distribution, such as the exponential value in an exponential distribution.
[0769] Maximum, minimum, mode, median, mean, standard deviation, variance, etc. are used to indicate the most appropriate range or the range that enables the AI / ML model or function to achieve a specific performance indicator.
[0770] It should be emphasized that the design of the above-mentioned auxiliary information solves the problem that the input distribution characteristics cannot be characterized as auxiliary information. When the distribution of the input data of the model or function is highly consistent with a specific predefined distribution (such as the difference between the statistical distribution curve of the input data and the probability density distribution curve of a predefined distribution is less than a certain threshold value), the UE can indicate a reference distribution to more accurately indicate the distribution of the input data. Moreover, even if the UE cannot give a reference distribution, it can describe the distribution characteristics of the input data from various aspects through reference values, characteristic values, maximum values, minimum values and other information, so that the NW can have a quantitative understanding of the distribution of the input or output data corresponding to the UE model / function, making it possible to report auxiliary information on the data distribution.
[0771] This information can indicate the distribution characteristics of the input and / or output of the training data of the UE's AI / ML model or function. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0772] A. When the reference distribution of the input (or output) data of the UE model or function is highly consistent with the distribution characteristics of the data in the current environment of the NW (for example, the deviation of the probability density distribution curve between the data distribution statistically obtained by the NW and the reference distribution reported by the UE is less than a certain threshold), it is decided to activate / switch to the AI / ML model or function of the UE, otherwise the AI / ML model or function of the UE is deactivated.
[0773] B. When the data characteristics of the input (or output) of the UE model or function are highly consistent with the distribution characteristics of the data in the current NW environment (for example, the mean of the NW environment is between the maximum and minimum values of the UE's input data, or the mean of the UE's input data is between the maximum and minimum values of the NW environment), it is decided to activate / switch to the UE's AI / ML model or function, otherwise, deactivate the UE's AI / ML model or function.
[0774] C. Based on management mode A or B, when the input data reference distribution and the output data reference distribution of the UE match, decide to activate / switch to the AI / ML model or function of the UE, otherwise deactivate the AI / ML model or function of the UE.
[0775] D. Based on management mode A or B, when only one of the input data reference distribution or the output data reference distribution of the UE can match, decide to activate / switch to the AI / ML model or function of the UE according to the one that has a greater impact on performance, otherwise deactivate the AI / ML model or function of the UE.
[0776] (5) Information related to the physical space of the training data corresponding to the AI / ML model or function.
[0777] a. Information related to the physical space of the base station.
[0778] a1. The area where the base station is located can be one or more of the following:
[0779] Areas of predefined representation;
[0780] Areas divided by longitude and latitude (e.g., each X longitude and Y latitude is divided into one area);
[0781] An area divided by administrative means (country, province, city, district, county, township, street, building, etc.).
[0782] a2. The height of the base station.
[0783] a3. The physical space related information between multiple base stations may be one or more of the following:
[0784] The average, maximum, and minimum values of the inter-station distances of multiple stations;
[0785] The coverage area of the plurality of stations (the coverage area of each of the plurality of stations and / or the joint coverage area of the plurality of stations).
[0786] a3. Reference scene of the area where NW is located.
[0787] The reference scenario may be some predefined scenarios, such as urban macrocell, urban microcell, rural cell, indoor factory cell. The wireless signal propagation characteristics between different predefined scenarios are different, such as different large-scale fading, and / or different small-scale channel characteristics, and / or different probabilities that the propagation path is a direct path, etc.
[0788] If the information indicates a reference scene, it means that the environment where the NW is located is the same as or similar to the environment of the reference scene.
[0789] It should be emphasized that in the above-mentioned auxiliary information, the scenes of the physical space related to the base station are quantitatively characterized by using methods such as area division, quantitative description of the height of the base station, quantitative description of the physical relationship between multiple base stations, and definition of reference scenes. This solves the problem that "scenes" are difficult to define in a standardized manner in the standard, making it possible for the UE to report its preferred NW-related scenes as auxiliary information for AI / ML models or functions.
[0790] b. Information related to the physical space of the UE.
[0791] b1. UE height.
[0792] b2. Moving speed of the UE. The moving speed may be an average value and / or a maximum value.
[0793] b3. UE's orientation.
[0794] It should be emphasized that the above-mentioned auxiliary information quantitatively describes the UE-related scenarios by using the height, direction and moving speed of the UE, which solves the problem that "scenario" is difficult to define in a standardized way in the standard. It makes it possible for the UE to report its preferred UE-related scenarios as auxiliary information for AI / ML models or functions.
[0795] This information can indicate the state of the physical space when the training data set of the UE's AI / ML model or function is collected. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more models / functions as follows:
[0796] A. When the NW physical space scene corresponding to the AI / ML model or function reported by the UE is the same / similar to the physical space scene of this NW, decide to activate / switch to the AI / ML model or function of the UE.
[0797] B. When the UE physical space scene corresponding to the AI / ML model or function reported by the UE is the same / similar to the physical space scene of the UE, decide to activate / switch to the AI / ML model or function of the UE.
[0798] C. Based on management methods A and B, the AI / ML model or function of the UE is activated / switched to when the NW physical space scene and the UE physical space scene corresponding to the AI / ML model or function reported by the UE match / match the physical space scene of the NW and the physical space scene of the UE;
[0799] This approach is relatively simple, but may miss opportunities for UE’s AI / ML models / functions to come into play.
[0800] D. Based on management methods A and B, if the NW physical space scenario and the UE physical space scenario corresponding to the AI / ML model or function reported by the UE only match / match one of the NW physical space scenario and the UE physical space scenario, the NW also decides whether to activate / switch to the UE's AI / ML model or function based on the impact of the generalization of the AI / ML model or function in the NW physical space and the UE physical space. For example, the CSI time domain prediction based on the AI / ML model has poor generalization to the UE speed (that is, the best AI / ML performance can only be obtained when the speed matches), but has good generalization to the NW physical space (that is, the physical space difference of the NW has little impact on the AI / ML performance), then the NW can decide to activate the AI / ML model when the UE speed matches (although the NW physical space does not match).
[0801] This method is relatively complex and requires the NW to determine in which scenarios / configurations / conditions the AI / ML model or function has good generalization performance, but it may maximize the UE's AI / ML model or function and maximize network performance.
[0802] In summary, the above auxiliary information is used to indicate the scenario, and / or configuration, and / or conditions when collecting training data for the AI / ML model or function on the UE side.
[0803] On the one hand, each AI / ML model or function may correspond to one piece of auxiliary information, or to multiple pieces of auxiliary information. Multiple pieces of auxiliary information indicate that the training data set of the AI / ML model or function is collected from multiple scenarios / configurations / conditions.
[0804] On the other hand, if the UE has multiple AI / ML models or multiple AI / ML functionality, the UE may indicate the auxiliary information corresponding to each AI / ML model or each AI / ML functionality, or divide the AI / ML model or AI / ML functionality into several sets and indicate the auxiliary information corresponding to each model set or functionality set.
[0805] After receiving the auxiliary information sent by the UE, the NW can reasonably manage the AI / ML model or function on the UE side based on the auxiliary information, for example:
[0806] A. Compare multiple configurations collected by the training data set corresponding to the UE's AI / ML model / function with the current configuration. If the current configuration belongs to one of the configurations collected by the training data set, it is considered that the AI / ML model on the UE side can work normally under the configuration of this cell, and the AI / ML model / function of the UE is activated.
[0807] B. Compare the base station ID when the training data sets corresponding to multiple AI / ML models of the UE were collected with the current base station ID, and find that the current cell does not belong to the cell from which the training data sets were collected. However, it is judged that the wireless environment of the current cell is similar to the wireless environment of the cell when the data was collected. It is believed that the AI / ML model on the UE side can also work normally in this cell, and the AI / ML model / function of the UE is activated.
[0808] Example 4: The auxiliary information sent by the UE to the NW is the ID of the training data set of the AI / ML model or function.
[0809] The auxiliary information sent by the UE to the NW is the ID of the training data set of the AI / ML model or function, which may include one or more of the following:
[0810] (1) The ID of the training data set can be an ID, which can be determined in the following way:
[0811] An ID determined in a predefined manner, or an ID configured by high-level signaling, or an ID configured manually (OAM mode).
[0812] a. ID confirmed in a predefined manner. For example, it can be agreed in a manner specified by the protocol that a training data set that meets a specific scenario / configuration / condition has a specific ID, such as the ID of a data set collected in an urban scenario is 0, the ID of a data set collected in a suburban scenario is 1, the ID of a data set collected in an indoor factory is 2, the ID of a mixed data set collected in an urban + suburban area is 3, and so on.
[0813] In addition, the ID can also be determined based on scene-related information that affects wireless communication performance, such as weather information in outdoor scenes. Specifically, the ID of data collected in urban areas + good weather is 11, the ID of data collected in urban areas + rainy weather is 12, the ID of data collected in suburban areas + good weather is 21, and so on.
[0814] b. ID configured by high-level signaling, such as RRC signaling, LPP signaling, or signaling from the core network, or ID configured by signaling from the application layer.
[0815] c. ID configured manually (OAM mode): For example, the UE manufacturer and the NW manufacturer / operator may agree to use a specific data set ID to represent a specific scenario / configuration / condition, and the ID may be manually configured.
[0816] d. A data set ID determined based on one or more of information including signal transmission related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information.
[0817] d1, L information among the information related to transmission, information related to signal reception, information related to signal quality, distribution characteristic information of model or function related data, and information related to physical space, respectively correspond to L bit fields, and each bit field occupies k1, k2, ..., k L bits, the L bit field constitutes the ID of the training data set, and the ID length K is greater than or equal to k1+k2+…+k L Bit; the value of each bit field corresponds to candidate information of a corresponding indication field.
[0818] For example, five pieces of information, including information related to transmission, information related to signal reception, information related to signal quality, distribution characteristic information of model or function-related data, and information related to physical space, correspond to five bit fields, each of which occupies k1, k2, ..., k5 bits. The five bit fields constitute the training data set ID, and the ID length is K = k1, k2, ..., k5. Among them, the SNR range in the signal quality-related information is divided into seven regions, so k3 = ceil (log2 (7)) = 3 bits are used to represent the seven regions, and the 3-bit value {000, 001, ... 101, 110} represents one of the seven SNR regions.
[0819] d2. The combination of L information among the sending related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information is mapped into an ID of length K, where K satisfies 2 K The minimum integer value of the number of candidates for a combination of L information that is greater than or equal to L; the value of this ID corresponds to a candidate for a combination of information.
[0820] For example, there are three pieces of information {base station ID, UE height, SINR} in the information related to transmission, signal reception, signal quality, distribution characteristics of model or function related data, and physical space related information that determine the data set ID, and there are 60 possible candidate combinations of {base station ID, UE height, SINR}, so K=6 (2 6=64) bits of ID represent the 60 combinations, and the value of ID {000000, 000001, ..., 111011} represents one of the 60 combinations.
[0821] (2) The ID of the training data set is a plurality of (sub) IDs, and the plurality of (sub) IDs are determined in the following manner:
[0822] a. Each (sub) ID corresponds to one of the information related to sending, related to signal reception, related to signal quality, distribution characteristic information of model or function-related data, and related to physical space. L (sub) IDs correspond to L information, respectively indicating a candidate item of one of the information related to sending, related to signal reception, related to signal quality, distribution characteristic information of model or function-related data, and related to physical space.
[0823] For example, there are three pieces of information {base station ID, UE height, SINR} in the information related to transmission, signal reception, signal quality, distribution characteristics of model or function related data, and physical space related information to determine the data set sub-ID. Then the data set has three (sub) IDs. The value of the first (sub) ID represents the base station ID, the value of the second (sub) ID represents the UE height, and the value of the third (sub) ID represents the SINR
[0824] b. Multiple IDs determined in a predefined manner, or multiple IDs configured by high-level signaling, or multiple IDs configured manually (OAM mode).
[0825] It should be emphasized that in this embodiment, by establishing a one-to-one mapping relationship between the auxiliary information and the dataset ID, so that the dataset ID carries the auxiliary information, or by pre-negotiation between the UE and the NW, assisted by manual configuration / high-level signaling configuration, the NW and the UE can align the understanding of the applicable scenarios / configurations / conditions of the AI / ML model or function according to the dataset ID reported by the UE, so that the dataset ID can characterize the characteristics of the training data in a quantitative way, so it becomes possible for the UE to report the dataset ID corresponding to its own AI / ML model or function as auxiliary information.
[0826] In this example, the NW can determine the matching between the characteristics of the training data set of the UE's AI / ML model or function and the characteristics of the cell based on the training data set ID reported by the UE, so as to reasonably manage the AI / ML model or function on the UE side. After the NW obtains the auxiliary information, it uses the auxiliary information to manage one or more of the following models / functions:
[0827] A. According to the dataset ID, determine the current NW scenario / configuration / condition, and compare the scenario / configuration / condition corresponding to the training data of the UE's AI / ML model or function. When one or more or all of the scenarios / configurations / conditions match, determine that the UE's AI / ML model or function can be activated.
[0828] B. Determine whether the NW itself participates in the data collection of the dataset corresponding to the dataset ID. When the NW itself participates in the data collection of the dataset corresponding to the dataset ID, determine whether the AI / ML model or function of the UE can be activated.
[0829] C. The NW itself saves / maintains relevant information of "dataset IDs suitable for AI / ML models or functions used in the current NW", such as a list or set (but the NW itself does not necessarily participate in the data collection corresponding to each dataset). The list or set can be manually configured or come from high-level information; when the dataset ID reported by the UE is in the list or set of dataset IDs saved / maintained by the NW, it is determined that the AI / ML model or function of the UE can be activated.
[0830] Example 5: The UE sends auxiliary information related to the AI / ML model or function on the UE side or auxiliary information related to the training data set of the AI / ML model or function on the UE side, as well as the ID of the training data set of the AI / ML model or function to the NW.
[0831] The training data set ID carries / indicates K pieces of information including sending related information, signal reception related information, signal quality related information, distribution characteristic information of model or function related data, and physical space related information, but does not carry / indicate the other J pieces of information; the UE can send the "training data set ID" and "the other J pieces of auxiliary information" to the NW, so that the NW can determine the match between the characteristics of the training data set of the UE's AI / ML model or function and the environment / configuration / conditions of the cell based on the "training data set ID and the other J pieces of auxiliary information", thereby reasonably managing the AI / ML model or function on the UE side.
[0832] For example, the training data set ID indicates / carries sending-related information and signal reception-related information, but does not carry / indicate information related to signal quality, distribution characteristic information of model or function-related data, and information related to physical space.
