INFORMATION TRANSMISSION METHOD AND APPARATUS

[0001] This application is a continuation application under 35 U.S.C. 111(a) of International Patent Application PCT/CN2023/094146 filed on May 15, 2023, and designated the U.S., the entire contents of which are incorporated herein by reference.

[0002] This disclosure relates to the field of communication technologies.

[0003] As low-frequency spectrum resources become scarce, the millimeter wave band can provide greater bandwidth and has become an important frequency band for 5G New Radio (NR) systems. Millimeter waves have different propagation characteristics from traditional low-frequency bands due to their shorter wavelength, such as higher propagation loss, poor reflection and diffraction performance, etc. Therefore, larger antenna arrays are usually used to form shaped beams with greater gain, overcome propagation losses, and ensure system coverage.

[0004] With the development of artificial intelligence (AI) and machine learning (ML) technologies, applying AI/ML technology to wireless communication to solve the difficulties of traditional methods has become a current technological direction. The application of AI/ML models in wireless communication systems, especially in air interface transmission, is a new technology in the 5G Advanced and 6G stages.

[0005] For example, for reporting Channel State Information (CSI), using Autoencoder network in deep learning on the terminal device side to encode/compress CSI with AI encoder, and decoding/decompressing CSI with AI decoder on the network device side can reduce feedback overhead. For example, in beam management, using AI/ML models to predict the spatially optimal beam pair based on a small number of beam measurements can reduce system load and latency.

[0006] It should be noted that the above description of the background is merely provided for clear and complete explanation of this disclosure and for easy understanding by those skilled in the art. And it should not be understood that the above technical solution is known to those skilled in the art as it is described in the background of this disclosure.

[0007] In 5G and 6G systems, a wide range of terminal technology features (UE features) are defined. Not all features are necessarily supported by a terminal. A network learns support of the UE features through query and reporting of a terminal equipment capability, i.e. UE capability, so that the network may have an understanding of the UE capability, thereby providing a foundation for its subsequent scheduling, configuration and communication of the terminal.

[0008] According to the current trends in 5G-advanced and 6G technologies, a terminal equipment may possibly support multiple AI/ML features. A feature can be more specifically described by functional parameters of a predefined feature group. Features in each feature group can be regarded as a sub-feature, or may be referred to as a functionality. Another possibility is to activate or enable a functionality at the terminal side by transmitting configurations pre-defined features and feature groups by the network side to the terminal equipment. For an AI/ML feature or AI/ML functionality enabled or activated by the network side, the network side monitors performances of the AI/ML feature or functionality.

[0009] However, it was found by the inventor that a response of the network side to monitoring the performances of the AI/ML feature or functionality is relatively slow or inaccurate, resulting in an inability to fully utilize the AI/ML functionality to improve communication quality.

[0010] In order to solve at least one of the above problems, embodiments of this disclosure provide an information transmission method and apparatus.

[0011] According to a first aspect of the embodiments of this disclosure, there is provided an information transmission method, including: transmitting, by a terminal equipment, indication information on an AI/ML feature and/or functionality to a network device.

[0012] According to a second aspect of the embodiments of this disclosure, there is provided an information transmission method, including: receiving, by a network device, indication information on an AI/ML feature and/or functionality transmitted by a terminal equipment.

[0013] According to a third aspect of the embodiments of this disclosure, there is provided an information transmission apparatus, configured in a terminal equipment, the apparatus including: a first transmitting unit configured to transmit indication information on an AI/ML feature and/or functionality to a network device.

[0014] According to a fourth aspect of the embodiments of this disclosure, there is provided an information transmission apparatus, configured in a network device, the apparatus including: a second receiving unit configured to receive indication information on an AI/ML feature and/or functionality transmitted by a terminal equipment.

[0015] According to a fifth aspect of the embodiments of this disclosure, there is provided a computer readable program, which, when executed in an information transmission apparatus or a terminal equipment, will cause the information transmission apparatus or the terminal equipment to carry out the information transmission method as described in the first aspect of the embodiments of this disclosure.

[0016] According to a sixth aspect of the embodiments of this disclosure, there is provided a computer readable program, which, when executed in an information transmission apparatus or a network device, will cause the information transmission apparatus or the network device to carry out the information transmission method as described in the second aspect of the embodiments of this disclosure.

[0017] According to a seventh aspect of the embodiments of this disclosure, there is provided a computer readable medium, including a computer readable program, which will cause an information transmission apparatus or a terminal equipment to carry out the information transmission method as described in the first aspect of the embodiments of this disclosure.

[0018] According to an eighth aspect of the embodiments of this disclosure, there is provided a computer readable medium, including a computer readable program, which will cause an information transmission apparatus or a network device to carry out the information transfer method as described in the second aspect of the embodiments of this disclosure.

[0019] An advantage of the embodiments of this disclosure exists in that the terminal equipment transmits the indication information on an AI/ML feature and/or functionality to the network device, hence, the network device may timely and accurately learn an actual situation of performances of the AI/ML feature and/or functionality, and achieves accurate operations of the AI/ML feature and/or functionality, thereby fully utilizing the AI/ML functionality to improve communication quality, and improving performances of the communication system.

[0020] Another advantage of the embodiments of this disclosure exists in that the implementation of the AI/ML model of the terminal equipment is invisible to the network device, and the terminal equipment may observe and monitor the model at the terminal side in a timely and accurate manner. The result of the monitoring may more accurately and timely reflect performances of functional levels. The terminal equipment transmits indication or request information regarding changes in the model at the terminal side or its performance evaluation of the functional levels to the network device, which is helpful to the operations of the functionality by the network device. Compared with a solution where the terminal equipment is not used to transmit the information, the AI/ML functionality may be timely and reliably used to improve communication quality, and improve performances of the communication system.

[0059] Scenarios of the embodiments of this disclosure shall be described below by way of examples; however, this disclosure is not limited thereto.

[0060] FIG. 1 is a schematic diagram of a communication system of this disclosure, in which a case where a terminal equipment and a network device are taken as examples is schematically shown. As shown in FIG. 1, the communication system 100 may include a network device 101 and a terminal equipment 102. For the sake of simplicity, an example having only one terminal equipment and one network device is schematically given in FIG. 1; however, the embodiments of this disclosure is not limited thereto.

[0061] In the embodiments of this disclosure, existing services or services that may be implemented in the future may be performed between the network device 101 and the terminal equipment 102. For example, such services may include but not limited to an enhanced mobile broadband (eMBB), massive machine type communication (MTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0062] In the embodiments of this disclosure, high-layer signaling may be, for example, radio resource control (RRC) signaling; for example, it is referred to an RRC message, which includes an MIB, system information, and a dedicated RRC message; or, it is referred to an as an RRC information element (RRC IE). Higher-layer signaling may also be, for example, medium access control (MAC) signaling, or an MAC control element (MAC CE); however, this disclosure is not limited thereto.

[0063] In the embodiments of this disclosure, the network device learns support of UE features through query and reporting of a terminal equipment capability (UE capability), so that the network may have an understanding of the UE capability, thereby providing a foundation for its subsequent scheduling, configuration and communication of the terminal.

[0064] FIG. 2 is a schematic diagram of exchange between the network device and the terminal equipment. As shown in FIG. 2, the network device transmits a UE capability enquiry request, such as UECapabilityEnquiry, to the terminal equipment (UE), and the terminal equipment reports its UE capability information, such as UECapabilityInformation, to the network device.

[0065] For an equipment having AI/ML functional modules, such as the terminal equipment, this functionality may possibly not be a functionality that the terminal equipment must support. According to a current technical trend in 5G-Advanced and 6G, a terminal equipment may possibly support multiple AI/ML features. A feature may be described more specifically by functional parameters of a predefined feature group.

[0066] In the embodiments of this disclosure, for a certain use case or communication functionality, such as CSI feedback, CSI prediction, beam management, beam prediction, positioning, and mobility management, etc., it may be classified as a feature, such as a CSI feedback AI/ML feature, a CSI prediction AI/ML feature, a beam management AI/ML feature, and a positioning AI/ML feature, etc.

[0067] In the embodiments of this disclosure, each feature may be further subdivided into feature groups, and features in each group may be regarded as a sub-feature, or may be referred to as a functionality.

[0068] For example, an AI/ML feature or a feature group includes one or more AI/ML functionalities.

[0069] The AI/ML functionality of the terminal equipment may also be reported by the network device according to the capability of the terminal equipment, and is configured to the terminal equipment based on a capability and judgment of the network device, thereby configuring one or more capabilities of the terminal equipment, or activating one or more capabilities of the terminal equipment.

[0070] The AI/ML functionality of the terminal equipment may also be reported by the network device according to the functionality of the terminal equipment, and is configured to the terminal equipment based on a capability and judgment of the network device, thereby configuring one or more capabilities of the terminal equipment, or activating one or more capabilities of the terminal equipment. The reporting of the functionality of terminal equipment described here is different from a capability reporting process of the terminal equipment, and corresponds to short-term, temporary, or current AI/ML function information reported by the terminal equipment to the base station according to support of functional features or functionalities in the short-term, temporary, or current situation.

[0071] In the embodiments of this disclosure, a functionality may also be referred to as a sub-feature, and different sub-features are distinguished by corresponding parameters or applicable conditions. Different sub-features or functionalities may have identifiers (IDs) or pre-defined corresponding indices.

[0072] Hence, different features may be distinguished by different feature identifiers, and different sub-features or functions under a feature may be distinguished by different sub-feature IDs or functionality IDs, or, different functionalities may be reported by the network device according to the capability of the terminal equipment and configured to the terminal equipment.

[0073] As described above, an AI/ML feature or feature group includes one or more AI/ML functionalities. For example, for a CSI prediction feature, corresponding to this feature, there may further be a functionality of low movement speed prediction and a functionality of high movement speed prediction.

[0074] A list of these sub-features or functionalities and related parameters thereof may be predefined and used for the common understanding of communication capability information between the network side and the terminal side.

[0075] To achieve a functionality, the terminal equipment may be specifically implemented by one AI/ML model or multiple AI/ML models.

[0076] In some embodiments, multiple functionalities may be implemented by one AI/ML model, depending on specific implementation of the terminal equipment, and methods and manners related to the implementation may not be necessarily notified to the network device.

[0077] In the embodiments of this disclosure, from the perspective of a logical model, it is generally defined that a model corresponding logically to a functionality is a logical model, and a logical model may be specifically implemented by one or more physical models. For the convenience of description, the embodiments of this disclosure does not further distinguish between logical models and physical models. That is, the model in the embodiments of this disclosure may be a logical model or a physical model.

[0078] In the embodiments of this disclosure, when a functionality is implemented by multiple models, different models may correspond to different scenarios, different sites, different cells, different configurations, and different applicable conditions, etc., which is determined by a training and development process of the models.

[0079] FIG. 3 is a schematic diagram of an equipment having an AI/ML functional module. The equipment may be a terminal equipment or a network device. The terminal equipment or the network device has an AI/ML functional module. For example, as shown in FIG. 3, the terminal equipment or the network device has a unit of an AI/ML feature/feature group, and there is at least one functionality unit in the unit of the AI/ML feature/feature group, such as a first functionality unit and a second functionality unit. For example, as shown in FIG. 3, the first functionality is implemented by at least one model from model a, model b and model c, etc., and the second functionality is implemented by at least one model from model x, model y and model z, etc. In some embodiments, the above functionality units may possibly also include multiple sub-functionalities, in which case a functionality unit may be regarded as a functionality group.

[0080] In the embodiments of this disclosure, the network device performs AI/ML-related capability enquiry on the terminal equipment, and the terminal equipment reports a corresponding capability according to the enquiry.

[0081] FIG. 4 is another schematic diagram of exchange between the network device and the terminal equipment. As shown in FIG. 4, the network device performs AI/ML-related capability enquiry on the terminal equipment, i.e. UE AI/ML capability enquiry, and the terminal equipment reports to the network device according to the enquiry, i.e. UE AI/ML capability reporting.

[0082] According to the UE AI/ML capability reporting, the network device further transmits a control message to activate or enable an AI/ML feature or feature group, or a specific functionality, of the terminal side. As shown in FIG. 4, the network device performs UE AI/ML feature and/or functionality activation on the terminal equipment.

[0083] In some embodiments, the activation may be achieved via the feature ID, sub-feature ID, functionality ID, or by a related configuration of a functionality. For example, in a CSI reporting configuration, a specific functionality may be activated by a configuration of an AI/ML IE.

[0084] Or, activation of a functionality may be indicated by an ID of the CSI reporting configuration or a resource (or resource set) configuration in combination with an AI/ML activation instruction, or equivalently, activation of AI/ML implementation to which the configuration corresponds.

[0085] After receiving relevant activation information, the terminal equipment enables a corresponding AI/ML model according to its implementation to perform measurement and reporting.

[0086] However, it was found by the inventor that there exists a problem that specific model information used by the terminal side does not need to be notified to the network side.

[0087] For example, corresponding to the first functionality, the number of models and which model or models are used by the terminal equipment, such as whether a model is used, such as model A, or whether model a and model b, or whether model a, model b and model c, etc., is/are used, are specific implementation information of the terminal, which are generally not needed to be notified to the network side.

[0088] For an AI/ML feature or functionality that is enabled or activated by the network side, the network side needs to perform basic performance monitoring on the feature or functionality. At the same time, when the terminal side implements the activated feature or functionality by using a specific model, model-level performance monitoring or input-output-related monitoring needs to be performed.

[0089] In addition, when an model or a group of models used by the terminal equipment is not adapted to a current application scenario or applicable condition, the terminal equipment may autonomously switch models or model groups.

[0090] Model switching at the terminal side may not be notified to the network side. However, due to lack of information on terminal model switching, the AI/ML functionality monitoring at the network side will transmit a command to activate or stop AI/ML features or functionalities to the terminal equipment when it determines that AI/ML performance is poor. This is actually an inappropriate operation because the performance of the terminal equipment after model switching may be very good.

[0091] The embodiments of this disclosure provide an information transmission method, which shall be described from a terminal equipment side.

[0092] FIG. 5 is a schematic diagram of the information transmission method of the embodiments of this disclosure. As shown in FIG. 5, the method includes:

[0093] 501: transmitting indication information on an AI/ML feature and/or functionality by the terminal equipment to a network device.

[0094] It should be noted that FIG. 5 only schematically illustrates the embodiments of this disclosure; however, this disclosure is not limited thereto. For example, an order of execution of the steps may be appropriately adjusted, and furthermore, some other steps may be added, or some steps therein may be reduced. And appropriate variants may be made by those skilled in the art according to the above contents, without being limited to what is contained in FIG. 5.

[0095] In some embodiments, the AI/ML feature includes at least one AI/ML functionality, the AI/ML functionality being referred to as an AI/ML sub-feature.

[0096] In some embodiments, the AI/ML feature includes at least one AI/ML feature group.

[0097] In some embodiments, the AI/ML feature group includes at least one AI/ML functionality.

[0098] For example, an AI/ML feature or a feature group includes one or more AI/ML functionalities. For example, for a CSI prediction feature, corresponding to this feature, there may further be a functionality of low movement speed prediction and a functionality of high movement speed prediction.

[0099] In some embodiments, the AI/ML feature has an AI/ML feature identifier (feature ID).

[0100] The AI/ML functionality has an AI/ML functionality ID, or the AI/ML sub-feature has an AI/ML sub-feature ID.

[0101] In some embodiments, the indication information includes information an AI/ML feature and/or functionality that the terminal equipment expects to use.

[0102] In some embodiments, the AI/ML feature and/or functionality that the terminal equipment expects to use refer(s) to an AI/ML feature and/or functionality that is/are determined by the terminal equipment according to monitoring and measuring a model implementing an AI/ML feature and/or functionality to be suitable for operation.

[0103] Thus, for the model at the terminal side, model-based input-output signal analysis may provide a more accurate evaluation of model performance compared to network side monitoring. In addition, evaluation of performances of an AI/ML feature and/or functionality to which the model corresponds be may further inferred. Configuration by the network may allow or enable performance evaluation at an AI/ML functionality level at the terminal side and related reporting to the network device, thereby achieving precise AI/ML functionality monitoring, functionality activation and deactivation, functionality selection and functionality switching, and fallback to a non-AI/ML mode. The AI/ML functionality is effectively utilized to enhance communication quality.

[0104] In some embodiments, the terminal equipment transmits the indication information to the network device in one of the following cases that:

• • [0105] the network device transmits configuration and/or an indication of the indication information to the terminal equipment;
  • [0106] the network device transmits configuration and/or indication related to an AI/ML feature and/or functionality of the indication information to the terminal equipment;
  • [0107] the network device transmits a measurement judgment indication related to the AI/ML feature and/or functionality operation of the indication information to the terminal equipment; and
  • [0108] the network device transmits at least one of a measurement metric, a condition and a performance threshold related to the AI/ML feature and/or functionality operation of the indication information to the terminal equipment.

[0109] In some embodiments, the AI/ML feature and/or functionality operation includes at least one of monitoring, selecting, switching, activating and deactivating the AI/ML feature and/or functionality and making the AI/ML feature and/or functionality fallback to a non-AI/ML mode.

[0110] FIG. 6 is a modular schematic diagram of the network device and the terminal equipment. As shown in FIG. 6, the network device includes a monitoring unit of feature and/or functionality performance, and the terminal equipment includes a unit of an AI/ML feature/feature group. In the unit of the AI/ML feature/feature group, there exists at least one functionality unit, such as a first functionality unit and a second functionality unit. For example, as shown in FIG. 6, the first functionality is implemented by at least one model from model a, model b and model c, etc., and the second functionality is implemented by at least one model from model x, model y and model z, etc. In addition, in the unit of the AI/ML feature/feature group, there exists also a model-level monitoring unit, i.e. a model-related monitoring and measurement unit.

[0111] The method and operations of the terminal equipment and the network device of the embodiments of this disclosure shall be described below with reference to various application scenarios.

[0112] In some embodiments, the indication information includes model indication information.

[0113] For example, the model indication information includes change information of a model or model group implementing the AI/ML feature and/or functionality.

[0114] In some embodiments, the change information of the model or model group includes at least one of the following information:

• • [0115] information on changes in a model or model groups;
  • [0116] identification information of the AI/ML feature and/or functionality and indication information of changes in the model or model group; and
  • [0117] identification information of the model or model group.

[0118] For example, the information on a change in the model or model group is represented by bit information. For example, a change in the model or model group is represented by 1 bit.

[0119] For example, the model or the model in the model group is in a bilateral model structure. The network device has a consistent understanding of the model identifier transmitted by the terminal. This identifier characterizes that a model or a model group at the terminal side may work together with a model or a model group at the network side, and sometimes they become paired identifiers.

[0120] In some embodiments, the model indication information is carried in relevant reporting information.

[0121] For example, the reporting information is CSI reporting information, and in an IE related to AI/ML in the CSI reporting configuration, indication information reporting that represents model changes is predefined.

[0122] In some embodiments, the terminal equipment transmits the model indication information to the network device via uplink signaling.

[0123] For example, the model indication information is carried by UCI or an MAC CE or RRC signaling.

[0124] In some embodiments, on a physical channel, the model indication information is transmitted via a PUCCH or a PUSCH.

[0125] The application scenario shall be described below with reference to the accompanying drawings.

[0126] FIG. 7 is a schematic diagram of exchange between the network device and the terminal equipment in application scenario 1 in the embodiments of this disclosure. As shown in FIG. 7, the network device performs UE AI/ML feature and/or functionality activation on the terminal equipment. After the AI/ML feature and/or functionality is/are activated or enabled, the terminal equipment correspondingly starts model a to perform relevant signal processing and simultaneously measures model use, such as features of signals input and output by model a. If the terminal equipment determines to switch to model b based on its measurement or other reasons, the terminal equipment will transmit relevant indication information to the network device accordingly, i.e. model-related indication information.

[0127] Furthermore, it should be noted that the above description is also applicable to switching of model groups, such as switching from model group a to model group b. Here, each model group may correspond to multiple models under multiple sub-conditions of a condition applied by it.

[0128] In addition, the above description is also applicable to stop of the model or model group, and at this moment, the indication information of the model corresponds to the stop of the model.

[0129] Moreover, when the model indication information corresponds to different model operations, such as model switching, model stop, model starting, and model updating, etc., different model operations may be represented by multiple pieces of predefined bit information and taken as the model indication information.

[0130] The network side monitors performance of the AI/M feature and/or functionality activated by it. After receiving the model-related indication information transmitted by the terminal equipment, the network device may adjust its monitoring strategy accordingly, such as resetting a monitoring-related event counter, a timer, and a model monitoring calculation method, etc., that is, monitor and determining a corresponding signal transceiving performance after the terminal side switches the model. Thus, model monitoring and determination of activation performances by the network side may be more accurate.

[0131] FIGS. 8A and 8B are schematic diagrams of comparison between an exchange process in the method of the embodiments of this disclosure and an exchange process in an existing method. As shown in FIG. 8A, in the existing method, when a network side monitors that performances of an AI/ML feature/functionality are poor, it decides to stop the AI/ML feature/functionality and transmits a deactivation command to a terminal side, and the terminal side may only stop using a model which it has just switched to and believed by it that may have good performance. This may lead to degradation in subsequent communication performance. On the contrary, as shown in FIG. 8B, in the embodiments of this disclosure, the network side readjusts its monitoring and decision-making strategy after receiving the model-related indication information. Even if performances of the monitored AI/ML feature/functionality are poor before the information is received, the network side may reset monitoring indices, proceed with keeping an active state of the AI/ML functionality, and further monitor a new model used by the terminal side. Hence, by continuously using the AI/ML functionality, the communication process may benefit from gains brought by the AI/ML functionality for a longer period of time.

Application Scenario 2: Deactivation of the AI/ML Feature and/or Functionality and/or Fallback to a Non-AI/ML Mode

[0132] In some embodiments, the indication information includes deactivation request information for an AI/ML feature and/or functionality in an active state and/or request information on fallback to a non-AI/ML mode.

[0133] In some embodiments, the deactivation request information includes at least one piece of the following information:

• • [0134] identification information of the AI/ML feature and/or functionality in the active state;
  • [0135] indication information on deactivation;
  • [0136] information on applicability for a deactivated AI/ML feature and/or functionality;
  • [0137] quality information of a signal used in judging a deactivated AI/ML feature and/or functionality;
  • [0138] identification information of reporting configuration; and

[0323] That is, an explicit indication is introduced to mark tested models and untested models. The indication may be indicating by the part of bit information or numerical information in the model identifier, for example, 1 in the bit string or numerical string of the model identifier is used to represent that it has been tested, and 0 therein is used to represent that it has not been tested.

[0324] In some embodiments, the indication may be that an untested model does not have a model identifier, and only a tested model has an identifier.

[0325] The above model identifier is a global identifier, which may be given offline, or may be given when the model is registered in the network.

[0326] In some embodiments, the test includes at least one of interoperability test, RAN4 test and network access test.

[0327] On the other hand, for a model that has not undergone interoperability test, RAN4 test and network access test, it does not have an initial global model identifier, and needs to undergo an online testing verification process. After the test and verification satisfy requirements on performances, the network side confers a global model in a process of model registration or model identification.

[0328] Specifically, it may be that the network device transmits relevant model information to a network element responsible for managing global model identifiers after the model testing and verification satisfy preset conditions, so as to obtain the global identifier.

[0329] Or, after the model testing and verification satisfy the conditions, the terminal equipment initiates a model registration or recognition request for the model to the network side, transmits relevant model information to the network element responsible for managing global model identifiers, and obtains the global identifier.

[0331] 1801: for an AI/ML model that does not have a global identifier, after testing and verification satisfy preset conditions, providing a global identifier of the AI/ML model by a network side.

[0332] In some embodiments, after testing and verification satisfy preset conditions, the network side provides a global identifier of the AI/ML model in a process of model registration or model identification.

[0333] In some embodiments, after testing and verification satisfy preset conditions, the network device or terminal equipment transmits relevant model information to a network element responsible for managing global model identifiers, and obtains a global identifier of the AI/ML model from the network element.

[0334] In some embodiments, the test includes at least one of interoperability test, RAN4 test, and network access test.

[0335] Or, for all models that are not registered on the network, their initial model identifiers include identifications of whether they have passed interoperability test, RAN4 test, and network access test, etc. For models that have not undergone the above test, they need to be registered on the network, and undergo a necessary testing and verification process before being used, and after conditions are satisfied, they are granted relevant permissions or initial identification information.

[0336] Based on these permission information or initial identification information, the terminal side or base station initiates a model registration or model recognition request for the model to the network side, transmits relevant model information to the network element responsible for managing global model identifiers, and obtains the global identifier.

[0337] FIG. 19 is a further schematic diagram of the method for identifying an AI/ML model of the embodiments of this disclosure. As shown in FIG. 19, the method includes:
