[0031] It should be understood that all or part of the functions of the communication device in the present application can also be implemented by software functions running on hardware, or by virtualized functions instantiated on a platform (such as a cloud platform).

[0032] AI / ML model

[0033] The 3rd generation partnership project (3GPP) studied in the 18th release (Rel 18) whether AI / ML models (or AI / ML algorithms) can help improve the performance of the physical layer, and the relevant research results are recorded in the technical report TR38.843. In addition to recording the evaluation methods and results related to AI / ML models, the technical report also records the steps and content of how to manage AI / ML on the network side or the terminal device side or both sides. These related contents constitute the content of life cycle management (LCM) in the technical report. It should be noted that LCM is a relatively broad term, and its content includes data collection, model training, function / model identification, model transmission, model inference, selection, activation, deactivation, replacement and fallback of function / model, monitoring of function / model, model update, and reporting of terminal device capabilities.

[0034] In some embodiments, the AI / ML model can be used for beam measurement prediction for beam management. As an example, the AI / ML model can be applied to spatial domain beam prediction, that is, the best beam (such as the beam with the strongest wireless signal) in the full set of beams can be predicted by measuring a subset of beams in a set, using the spatial correlation between beams. For example, the AI / ML model can be used to predict the beam with the strongest wireless signal or a pair of beams in the full set of beams, which can be used for downlink transmission and reception. As another example, the AI / ML model can be applied to time domain beam prediction, that is, the measurement result of the beam in the current time slot can be predicted according to the measurement results of the historically measured beams and / or the already predicted beams, using the correlation of the beams over time. The AI / ML model for beam prediction in the spatial domain and the time domain is not only technically feasible, but also can provide higher performance improvement.

[0035] In some embodiments, the techniques of beam measurement prediction using AI / ML model can be applied to other scenarios, for example, to RRM measurement, so that the network can make further handover decisions as early as possible according to the predicted RRM measurement results, the essence of which is to apply the principles for beam management to the prediction or speculation of mobility measurement and / or mobility events. As an example, 3GPP has studied the application of techniques for beam measurement prediction to RRM measurement through a standing item (RP-234055) at RAN#102 meeting.

[0036] In some embodiments, the AI / ML model (such as the AI / ML model applied in the RRM measurement scenario, the AI / ML model applied in the beam management scenario, etc.) can be deployed on the terminal device side or on the network device side.

[0037] In some embodiments, the device running the model can need other devices to provide some auxiliary information to improve the performance of the model, such as the need for other devices to provide auxiliary information to improve the prediction accuracy of the model, or the need for other devices to provide auxiliary information to select (choose) a model that can obtain better prediction results. Taking the terminal device as an example, the model running on the terminal device side can need the network device to provide auxiliary information (such as real-time load information on the network side) to improve the performance of the model. Taking the network device as an example, the network device can need the terminal device to provide auxiliary information (such as the location information of the terminal device) to improve the performance of the model.

[0038] The following describes how to use auxiliary information to improve the performance of the model.

[0039] In some embodiments, the performance of the model can be limited by many factors, such as the configuration on the network device side, the state on the terminal device side, etc. For example, if the training data used by a model is obtained when the speed of the terminal device is 30 km / h, but it is applied to a terminal device with a speed of 60 km / h for inference, the inference result is likely to be poor, or even completely unacceptable. In this case, in order to guarantee the performance of the model, auxiliary information can be provided in the running process of the model (such as the training, inference, supervision, etc. of the model) to improve the performance of the model.

[0040] As an implementation, it can be explicitly indicated in the training process of the model which data is collected when the speed of the terminal device is 30 km / h and which data is collected when the speed of the terminal device is 60 km / h. In this way, when the model is inferred, the current speed of the terminal device can be explicitly informed, and a more accurate model prediction result can be obtained.

[0041] That is, the auxiliary information can have multiple uses in the running of the model. For example, the auxiliary information can be used as input information of the model to improve the prediction accuracy of the model. For another example, the auxiliary information can be used as selection information of the model to select a model that can obtain better prediction effect.

[0042] Taking the speed information of the terminal device as an example, the speed information of the terminal device (for example, the speed of the terminal device is 30 km / h) can be used as input information of the model during model training, and the model may not be able to train or infer without this information.

[0043] Taking the speed information of the terminal device as an example, assuming that the device side running the model contains multiple models corresponding to terminal devices with different speeds, the speed information of the terminal device can be used as selection information of the model to select a suitable model for inference. For example, the multiple models include three models, model A is used for inference at a speed of 30 km / h, model B is used for inference at a speed of 60 km / h, and model C is used for inference at a speed of 90 km / h. If the device running the model learns that the current speed of the terminal device is 60 km / h, it can select model B for inference.

[0044] Taking the antenna configuration information of the cell as an example, assuming that in the beam management scenario, the terminal device side needs to train a model for beam measurement prediction. Considering the generalization ability of the model, the model needs to support the terminal device to perform beam measurement prediction under multiple different cell coverage. However, the antenna configurations of different cells may be different, and the channel coverage corresponding to different antenna configurations may differ greatly. In this case, if the model is trained only based on the beam measurement result, the prediction performance of the finally trained model may be poor. However, if the antenna configuration information of the cell can be used as input information of the model for model training, and the antenna configuration of the current cell is used for model selection during model inference, the prediction performance of the model can be greatly improved.

[0045] However, the above-mentioned auxiliary information can be relatively sensitive information for the information provider, and the device running the model usually does not want to obtain. For example, the terminal device can not want the network device to obtain its accurate position information, the network device can not want to inform the terminal device of the antenna configuration information of the cell, and the like. The reason why the information provider does not want to provide these auxiliary information is that, on the one hand, the privacy and security of the information are considered, and on the other hand, various manufacturers (such as terminal, network, chip manufacturers) and operators are concerned that if these information is leaked, there can be a risk of leaking core intellectual property rights. Taking the auxiliary information including the antenna configuration information of the cell as an example, the antenna configuration information belongs to the trade secret of the network manufacturer or operator (may disclose the reason why the signal coverage is good in a certain area), and the network manufacturer or operator certainly does not want to provide the antenna configuration information to the third party (such as the terminal device manufacturer), and there can be a security risk if these information is provided to the third party, for example, the hacker knows and performs a specific network attack.

[0046] To solve the above-mentioned problem, the embodiments of the present application provide a wireless communication method and a communication device, which can process the sensitive information (i.e. the second information below) of the device to obtain the first information, and then send the first information to the device running the model, so as to improve the running performance of the model while avoiding directly transmitting the sensitive information of the device, which is beneficial to improve the privacy and security of data transmission.

[0047] Hereinafter, the first information and the second information mentioned in the embodiments of the present application are introduced.

[0048] In some embodiments, the second information includes information that the information provider (i.e. the provider of the second information, hereinafter referred to as the first device) does not expect the model running party (hereinafter referred to as the second device) to obtain. Or in other words, the second information includes information that the first device does not want (or does not expect) the second device to obtain. In other words, the first device does not want to provide the second information to the second device.

[0049] In some embodiments, the second information includes information that the first device does not expect the second device to obtain can be understood or replaced as the second information includes information that the first device does not expect the second device to directly obtain. Or in other words, the first device does not want to directly provide the second information to the second device. In some embodiments, the first device does not want to directly provide the second information to the second device can be understood as the first device does not want to provide the second information to the second device without processing the second information.

[0050] In some embodiments, the second information includes sensitive information of the first device. In some embodiments, the first device does not want to provide its sensitive information to the second device.

[0051] In some embodiments, the sensitive information of the first device can comprise privacy information of the first device.

[0052] In some embodiments, the second information can be applied in the model. For example, the second information can be used in one or more of the following: model training, model inference (usage), model monitoring, model selection.

[0053] Embodiments of the present application do not limit the model running on the second device side. Illustratively, the model running on the second device side can be an AI / ML model. As an example, the model running on the second device side can be an AI / ML model for beam management, RRM measurement, channel estimation, etc.

[0054] Embodiments of the present application do not limit the specific content of the second information, as long as the second information contains information that the first device does not want to provide to the second device. Illustratively, the second information is associated with one or more of the following: the location of the first device, the configuration of the first device, the high layer data of the first device.

[0055] In some embodiments, the second information comprises one or more of the following: location information of the first device, network configuration information of the first device, high layer data of the first device, hardware configuration information of the first device.

[0056] Embodiments of the present application do not limit the indication manner of the location information of the first device. As a possible implementation manner, the location information of the first device can be indicated by absolute position, for example, the location information of the first device can comprise the latitude and longitude coordinates of the first device. As another possible implementation manner, the location information of the first device can be indicated by relative position, for example, the location information of the first device can comprise the direction and distance of the first device relative to the base station to which the first device belongs, etc.

[0057] Embodiments of the present application do not limit the acquisition manner of the location information of the first device. For example, the location information of the first device is acquired by global navigation satellite system (GNSS) positioning. Alternatively, the location information of the first device is acquired by Beidou positioning.

[0058] The network configuration information of the first device can comprise any information related to the network configuration of the first device. Illustratively, the network configuration information of the first device can comprise one or more of the following: the electric tilt angle corresponding to the first device, the modulation mode of the first device, the network load information of the first device, the network topology structure of the first device, etc.

[0059] The high-layer data of the first device may, for example, comprise application layer data of the first device. Of course, the embodiments of the present application are not limited thereto, for example, the high-layer data of the first device may comprise packet data convergence protocol (PDCP) layer data of the first device, etc.

[0060] The high-layer data of the first device may, for example, comprise one or more of the following: attitude information of the first device, position information of the first device, environment information in which the first device is located, information collected by a sensor of the first device, etc.

[0061] The attitude information of the first device may, for example, comprise angle information (such as gyroscope angle) of the first device, angular velocity information of the first device, etc.

[0062] The environment information in which the first device is located may, for example, comprise information of an environment identified by the first device (such as an identified environment picture), temperature and humidity information of an environment in which the first device is located, etc.

[0063] The information collected by the sensor of the first device is not limited in the present application. For example, the information collected by the sensor of the first device may comprise one or more of the following: temperature information, humidity information, speed information, acceleration information, angle information, pressure information, etc.

[0064] The hardware configuration information of the first device may, for example, comprise antenna configuration information, modem module configuration information, power amplifier module configuration information, etc. of the first device. However, the embodiments of the present application are not limited thereto, and the hardware configuration information of the first device may also comprise other information, such as transceiver configuration information of the first device, etc.

[0065] In some embodiments, the first information is obtained by processing the second information, for example, by the first device processing the second information. In other words, the first information is the processed second information, or the first information is the processed sensitive information.

[0066] In some embodiments, the first information implies the second information. For example, the second information can be approximately known from the first information, but cannot be accurately known from the first information. Taking the speed information of the terminal device as an example, assuming that the second information is that the speed of the terminal device is 40 km / h, the first information can be that the speed of the terminal device is 30-60 km / h, or the first information can be an identifier indicating that the speed of the terminal device is 30-60 km / h. Taking the location information of the terminal device as an example, assuming that the second information is that the terminal device is 103.795 meters away from the base station 103, the first information can be that the terminal device is 100-200 meters away from the base station 103, or the first information can be an identifier indicating that the terminal device is 100-200 meters away from the base station 103, and the like. How to process the second information to obtain the first information will be described in detail later, which will not be described here.

[0067] In some embodiments, the first information can be applied to different stages of the model. For example, the second information can be applied to the training stage of the model and / or the inference stage of the model.

[0068] In some embodiments, the first information can be used for model input, for example, the first information can be used as input information when the second device trains and / or infers the model, so as to improve the prediction accuracy of the model.

[0069] In some embodiments, the first information can be used for model selection, for example, the first information can be used as auxiliary information for model selection to assist in selecting a model with better prediction effect. When the first information is A, the corresponding model is model 1, and when the first information is B, the corresponding model is model 2, then the second device can select model 1 for inference after learning that the first information is A. In some embodiments, the first information used for model selection can also be understood or replaced as: the first information is used as input information of the model during model inference.

[0070] The embodiments of the present application do not limit the specific content of the first information, and exemplarily, the first information is associated with one or more of the following: the location of the first device, the configuration of the first device, and the high-layer data of the first device.

[0071] In some embodiments, the first information includes one or more of the following: the location information of the first device, the network configuration information of the first device, the high-layer data of the first device, and the hardware configuration information of the first device.

[0072] In some embodiments, the type of information indicated by the first information is the same as the type of information indicated by the second information. For example, if the second information is used to indicate the location information of the first device, the first information is also used to indicate the location information of the first device. For another example, if the second information is used to indicate the speed information of the first device, the first information is also used to indicate the speed information of the first device.

[0073] The detailed content of the various information included in the first information is similar to the information included in the second information, and can be referred to the introduction of the second information above. For brevity, details are not repeated here.

[0074] It is mentioned above that the first information is obtained by processing the second information. How to process the second information to obtain the first information is introduced below.

[0075] In some embodiments, the processing of the second information is used to generalize (or fuzz) the second information, or the purpose of the processing of the second information is to generalize or fuzz the second information, so as to avoid the second information being directly acquired by the second device.

[0076] Embodiments of the present application do not limit the manner of processing the second information. Several implementation manners of obtaining the first information by processing the second information are exemplarily introduced below.

[0077] Implementation manner 1: mapping the second information according to a mapping relationship

[0078] In some implementation manners, there is a mapping relationship between the first information and the second information, and the second information can be mapped according to the mapping relationship between the two to obtain the first information.

[0079] In some implementation manners, the first information can be represented as a mapping identifier (ID). Embodiments of the present application do not limit the implementation form of the mapping ID. For example, the mapping ID can be a character, such as a number, a letter, a symbol, etc.

[0080] In some implementation manners, the first information can correspond to a type of second information, or in other words, the first information can correspond to a type of sensitive information. For example, the first information can correspond to the speed information of the terminal device. For another example, the first information can correspond to the acceleration information of the terminal device. For another example, the first information can correspond to the antenna configuration information of the network device, etc. An example is given below in combination with Table 1.

[0081] Table 1

[0082] The example of Table 1 is introduced taking the speed information of the terminal device as an example of the second information. As shown in Table 1, when the first information is 0, it indicates that the second information is the speed of the terminal device below 15 km / h; when the first information is 1, it indicates that the second information is the speed of the terminal device between 15-30 km / h; and when the first information is 2, it indicates that the second information is the speed of the terminal device between 30-60 km / h.

[0083] In some implementations, the first information can correspond to multiple types of second information, or in other words, the first information can correspond to multiple types of sensitive information. For example, the first information can correspond to speed information and acceleration information of the terminal device. For another example, the first information can correspond to speed information and angle information of the terminal device. For yet another example, the first information can correspond to antenna configuration information and power amplifier module configuration information of the terminal device, and so on. An example is given below in Table 2.

[0084] Table 2

[0085] The example of Table 2 is introduced by taking the speed information and the acceleration information of the terminal device as the second information. As shown in Table 2, when the first information is 0010, it indicates that the second information is that the speed of the terminal device is 15-30 km / h and the acceleration is 0-1 m / s 2 ; when the first information is 0100, it indicates that the second information is that the speed of the terminal device is 15-30 km / h and the acceleration is 1-2 m / s 2 ; when the first information is 0110, it indicates that the second information is that the speed of the terminal device is 30-60 km / h and the acceleration is 0-1 m / s 2 ; and when the first information is 1000, it indicates that the second information is that the speed of the terminal device is 30-60 km / h and the acceleration is 1-2 m / s 2 .

[0086] It should be noted that the mapping manner of Table 1 and Table 2 is only an example. For example, the first information can be identified from 0, or can be identified from 1, or can be identified by using characters, and so on. For another example, Table 1 and Table 2 only show the mapping relationship when the speed of the terminal device is lower than 60 km / h, and the mapping relationship of other speeds can be mapped according to actual needs.

[0087] The configuration manner of the mapping relationship between the first information and the second information is not limited in the embodiments of the present application. In some embodiments, the mapping relationship is pre-defined by a protocol. In some embodiments, the mapping relationship can be configured by a network device, for example, configured by high layer signaling (such as radio resource control (RRC) signaling).

[0088] The mapping manner of mapping the second information according to the mapping relationship to obtain the first information is simple and easy to operate.

[0089] Implementation 2: Character masking on the second information

[0090] In some implementations, part of the characters in the second information can be character-masked to obtain the first information.

[0091] In some implementations, if the string of the second information is long, part of the characters in the second information can be considered for character masking.

[0092] Embodiments of the present application do not limit the part of the characters that are masked. For example, the last few characters of the second information can be masked; or the first few characters of the second information can be masked; or the middle few characters of the second information can be masked, etc. Taking an example where the second information includes the network topology information of the first device, assuming the second information is 010000101, the character masking of the second information can include masking the second information as 0100xx101, where xx can be 00, 01, 10, 11, so as to ensure that the second information is not directly transmitted. Of course, the present application is not limited thereto, for example, the second information after masking (i.e. the first information) can also be 0100001xx, xx0000101, 01xxx0101, xxx000101, 01000xxxx, etc.

[0093] The character masking of the second information is advantageous in generalizing or blurring the second information, avoiding the second information being directly acquired, and avoiding the second information being reverse cracked, improving the security of the data.

[0094] Implementation 3: Truncating the second information

[0095] In some implementations, the second information can be truncated (e.g. the information bits of the second information are truncated) to obtain the first information.

[0096] In some embodiments, the truncating of the second information can include truncating the last few characters of the second information. Taking an example where the second information includes the location information of the first device, assuming the second information is the distance of the first device from the base station, which is 103.795 meters, the first information obtained after truncating the second information can be 103 meters, or can be 103.7 meters.

[0097] The truncating of the second information is advantageous in generalizing or blurring the second information, avoiding the second information being directly acquired, and avoiding the second information being reverse cracked, improving the security of the data.

[0098] It should be noted that the implementation manners of processing the second information mentioned in the embodiments of the present application can be used alone or in combination. As an example, the first information can be obtained by mapping the second information according to a mapping relationship and then performing character masking. Taking the speed information of the terminal device as the second information as an example, assuming that the speed of the terminal device is 60 km / h, the mapping ID after mapping according to the mapping relationship is 000010, and the first information obtained after performing character masking on the mapping ID is 000xx0. As another example, the first information can be obtained by mapping the second information according to a mapping relationship and then performing truncation processing. Still taking the speed information of the terminal device as the second information as an example, assuming that the speed of the terminal device is 60 km / h, the mapping ID after mapping according to the mapping relationship is 000010, and the first information obtained after performing truncation processing on the mapping ID is 0000 (the last two bits after truncation).

[0099] The embodiments of the present application are not limited to the above-mentioned several implementation manners of processing the second information, as long as the processing of the second information can generalize or fuzz the second information. As an example, the embodiments of the present application can fill (such as character filling) the second information to obtain the first information. Taking the network topology information of the first device as the second information as an example, assuming that the second information is 010000101, the first information obtained after filling the second information is 010000101001, 010000101010, etc. Taking the position information of the first device as the second information as an example, assuming that the second information is the distance of the first device from the base station, which is 103.795 meters, the first information obtained after filling the second information is 1103.795 meters, 1031.795 meters, 10301.795 meters, etc. As another example, the embodiments of the present application can process the second information in a manner similar to rounding (such as rounding, rounding down, rounding up, etc.), for example, assuming that the second information is the distance of the first device from the base station, which is 113.795 meters, the first information obtained after processing in a manner similar to rounding can be 100 meters, 110 meters, etc.

[0100] The embodiments of the present application utilize the generalization ability of the model, and use the processed second information (i.e., the first information) for model input and / or model selection to improve the running performance of the model. Specifically, the embodiments of the present application can use the second information as the input information of the model during model training, which makes the model tolerate the fuzzed second information to a certain extent; and subsequently, during model inference, the first information can be used as the model input or model selection, without inputting the original sensitive information (the second information).

[0101] For ease of understanding, an example is given below taking the application of the model in the RRM measurement scenario as an example.

[0102] In the RRM measurement scenario, the moving speed of the terminal device has a great influence on the result of the RRM measurement prediction. If a model running on the network device side is trained by data (such as measured reference signal receiving power (RSRP) values) of a terminal device with a speed of 30 km / h, when the model is used on a terminal device with a speed of 60 km / h, the result of the RRM measurement prediction can be very poor.

[0103] To solve the above problem, a feasible method is to simultaneously use the speeds of terminal devices corresponding to multiple groups of RSRP values (for example, RSRP values measured at 30 km / h, RSRP values measured at 60 km / h, and RSRP values measured at 90 km / h) as input information of the model for model training, and use the RSRP values and the speeds of the terminal devices as model inputs for model inference to obtain the result of the RRM measurement prediction.

[0104] For the model on the network device side, the speed of the terminal device is a non-mandatory reporting item in the current protocol, and generally the network device cannot obtain the speed information of the terminal device. In other words, the speed information of the terminal device is sensitive information (the second information mentioned above), and the terminal device generally does not want to provide it to the network device (involving user privacy issues). The above-mentioned processing of the second information into the first information can well solve this problem, for example: the speed of the terminal device is 40 km / h, and the terminal device only needs to report a value 2 (indicating that the speed is between 30 km / h and 60 km / h) to the network device, and does not need to report 40 km / h. In this case, the model on the network device side can use the first information (such as the mapping ID corresponding to the speed of the terminal device) during training and inference, rather than the specific speed of the terminal device.

[0105] The above describes the first information, the second information, and how to process the second information, and the following describes the flow of the method of the present application in combination with FIG. 2.

[0106] FIG. 2 is a flow diagram of a method of wireless communication provided by an embodiment of the present application. The method shown in FIG. 2 includes step S220, which is described below.

[0107] In step S220, the first device sends the first information to the second device.

[0108] In the embodiment of the present application, the first device is the provider of the first information. In some embodiments, the first device has control over the transmission of the second information. The first device is not specifically limited in the embodiment of the present application. Illustratively, the first device can be a terminal device or a network device.

[0109] In an embodiment of the present application, the second device is a receiver of the first information. In some embodiments, the second device is deployed with a model which requires the first information (or the second information) as input information of the model and / or selection information of the model. The second device is not limited in the embodiments of the present application. For example, the second device can be a terminal device or a network device.

[0110] As an example, the first device is a terminal device, and the second device is a network device.

[0112] It should be noted that, in the embodiments of the present application, the network device can be a network element in a core network or an access network device, which is not limited in the embodiments of the present application.

[0113] The transmission of the first information is introduced below.

[0114] The embodiments of the present application do not limit the bearing manner of the first information. For example, the first information can be borne in one or more of the following: non access stratum (NAS) signaling, RRC signaling, medium access control control element (MAC CE). Taking the first device and the second device as a terminal device and a network element in a core network respectively, the first information can be borne in the NAS signaling. Taking the first device and the second device as a terminal device and an access network device respectively, the first information can be borne in the RRC signaling and / or the MAC CE. However, the embodiments of the present application are not limited thereto, for example, the first information can also be sent in one or more of the following: downlink control information (DCI), uplink control information (UCI), service interface (for example, a service interface provided by a network element in a core network, a service interface provided by an access network device, a service interface provided by a terminal device) and the like.

[0115] In some embodiments, the sending of the first information is based on a period and / or an event. As an example, the sending of the first information is based on a period, that is, the first information is sent periodically. As another example, the sending of the first information is based on an event, that is, the first information is sent based on an event. As yet another example, the sending of the first information is based on a period and an event, for example, the first information is sent periodically after being triggered based on an event.

[0116] The embodiments of the present application do not limit the event triggering the sending of the first information. For example, the event triggering the sending of the first information can be associated with one or more of the following: a request of the second device, a location of the first device, a state of the first device, a configuration of the first device.

[0117] In some embodiments, the event triggering the sending of the first information can include one or more of the following: a request of the second device, a location change of the first device, a state change of the first device, a configuration change of the first device.

[0118] In some embodiments, the second device can request the first device to send the first information, for example, when the second device needs to train or infer a certain model, the model needs the first information as input information or selection information, the second device can request the first device to send the first information. However, the embodiments of the present application are not limited thereto, for example, the second device requesting the first device to send the first information can also be triggered based on one or more of the following: a location change of the first device, a state change of the first device, a configuration change of the first device, etc.

[0119] In some embodiments, the location change of the first device can include a cell change of the first device, such as the first device switching from one cell to another cell. In some embodiments, the location change of the first device can include a tracking area change of the first device, such as the first device entering from one tracking area to another tracking area. In some embodiments, the location change of the first device can include a cell cluster change of the first device, such as the first device entering from one cell cluster to another cell cluster. However, the embodiments of the present application are not limited thereto, for example, the location change of the first device can include that the first device moves a distance greater than a certain threshold within a period of time, etc.

[0120] In some embodiments, the state change of the first device can include a movement state change of the first device. For example, a change in the moving speed of the first device, such as the moving speed of the first device rising from 30km / h to 60km / h, the first device changing from a stationary state to a moving state. For example, a change in the moving direction of the first device, such as the first device turning or U-turning during movement. For example, a change in the moving acceleration of the first device, such as the moving acceleration of the first device rising from 1m / s 2 to 2m / s 2 , etc.

[0121] In some embodiments, the state change of the first device can include an environmental state change of the first device. For example, a change in the temperature, humidity, etc. of the environment in which the first device is located. As an example, the first device enters a dry area from a high humidity area. As another example, the first device enters a high temperature environment from a low temperature environment.

[0122] In some embodiments, the configuration change of the first device can comprise a network configuration change of the first device, or in other words, the configuration change of the first device can comprise a network environment state change of the first device. For example, a network load change of the first device, such as a sudden increase of the network load. For another example, an electrical tilt adjustment of the first device. For another example, a modulation mode change of the first device, and the like.

[0123] In some embodiments, the configuration change of the first device can comprise a hardware configuration change of the first device. For example, an antenna number change of the first device, such as an increase of the antenna number. For another example, a power amplifier module configuration change of the first device, and the like.

[0124] In some embodiments, the event is configured by the network device. For example, the network device can configure the terminal device to send the first information after the handover by high layer signaling (such as RRC signaling).

[0125] In some embodiments, the event is implemented based on the terminal device. For example, the terminal device determines to send the first information when the moving speed of the terminal device is greater than a preset threshold.

[0126] In some embodiments, the event is predefined by the protocol.

[0127] Other related descriptions about the first information can be referred to the foregoing, and will not be described here for brevity.

[0128] Continuing to refer to FIG. 2, in some embodiments, the method shown in FIG. 2 can further comprise step S210. In step S210, the second device sends a request to the first device, and the request is used to request the first information.

[0129] In some embodiments, after the first device receives the request sent by the second device, the first device can send the first information and / or a command to the second device. Or in other words, after the first device receives the request sent by the second device, the first device can respond to the request by sending the first information and / or the command to the second device. As an example, after the first device receives the request sent by the second device, the first device can send the first information to the second device. As an example, after the first device receives the request sent by the second device, the first device can send a command to the second device. As an example, after the first device receives the request sent by the second device, the first device can send a command and the first information to the second device.

[0130] The command sent by the first device to the second device will be described below.

[0131] In some embodiments, the above command can be used to instruct one or more of the following: to reject to provide the first information, to deactivate one or more models that require the first information as model input and / or model selection, to update one or more models that require the first information as model input and / or model selection, to switch a current model that requires the first information as model input and / or model selection to another model.

[0132] In some embodiments, the above command can be used to explicitly reject to provide the first information. For example, in the case that the first device is unwilling (unexpecting) to provide the first information, the first device can send a command explicitly rejecting to provide the first information.

[0133] In some embodiments, the first device sends a command to the second device, the command being used to deactivate one or more models that require the first information as model input and / or model selection, in which case it can be understood that the first device considers that the models on the second device side that require the first information as model input and / or model selection are no longer applicable.

[0134] The number of models deactivated by the above command is not limited in the embodiments of the present application. For example, the first device can send a command to the second device, the command being used to deactivate a current model that requires the first information as model input and / or model selection. Alternatively, the first device can send a command to the second device, the command being used to deactivate all models that require the first information as model input and / or model selection.

[0135] In some embodiments, the first device sends a command to the second device, the command being used to update one or more models that require the first information as model input and / or model selection, in which case it can be understood that the first device considers that the models on the second device side that require the first information as model input and / or model selection need to be updated to maintain normal functions.

[0136] The number of models updated by the above command is not limited in the embodiments of the present application. For example, the first device can send a command to the second device, the command being used to update a current model that requires the first information as model input and / or model selection. Alternatively, the first device can send a command to the second device, the command being used to update all models that require the first information as model input and / or model selection.

[0137] In some embodiments, the first device sends a command to the second device, the command being used to switch a current model that requires the first information as model input and / or model selection, in which case it can be understood that the first device considers that the current model on the second device side that requires the first information as model input and / or model selection is not applicable and needs to be switched to another model.

[0138] The embodiment of the present application does not limit the model after switching. For example, the model after switching can be a model that needs the first information as model input and / or model selection, or a model that does not need the first information as model input and / or model selection.

[0139] It should be noted that after the first device receives the request sent by the second device, the first device can send the first information and / or a command to the second device to respond in different ways. The following gives some examples of responses.

[0140] As an example, the first device can send the first information to the second device.

[0141] As an example, the first device can send a command to the second device, which is used to refuse to send the first information.

[0142] As an example, the first device can send a command to the second device, which is used to deactivate one or more models that need the first information as model input and / or model selection.

[0143] As an example, the first device can send a command to the second device, which is used to update one or more models that need the first information as model input and / or model selection.

[0144] As an example, the first device can send a command to the second device, which is used to switch the current model that needs the first information as model input and / or model selection to other models.

[0145] As an example, the first device can send a command to the second device, which is used to refuse to send the first information and deactivate one or more models that need the first information as model input and / or model selection.

[0146] As an example, the first device can send a command to the second device, which is used to refuse to send the first information and update one or more models that need the first information as model input and / or model selection.

[0147] As an example, the first device can send a command to the second device, which is used to refuse to send the first information, and deactivate and update one or more models that need the first information as model input and / or model selection. For example, the first device can instruct the second device to temporarily deactivate the model in the update during the update of the model.

[0148] As an example, the first device can send the first information and a command to the second device, which is used to update one or more models that need the first information as model input and / or model selection.

[0149] As an example, the first device can send the first information and a command to the second device, the command being used to switch a current model requiring the first information as model input and / or model selection to another model, e.g., to another model requiring the first information as model input and / or model selection.

[0150] As an example, the first device can send the first information and a command to the second device, the command being used to switch a current model requiring the first information as model input and / or model selection to another model, e.g., to another model not requiring the first information as model input and / or model selection.

[0151] As an example, the first device can send the first information and a command to the second device, the command being used to switch a current model requiring the first information as model input and / or model selection to another model, e.g., to another model not requiring the first information as model input and / or model selection.

[0152] As an example, the first device can send the first information and a command to the second device, the command being used to switch a current model requiring the first information as model input and / or model selection to another model, e.g., to another model not requiring the first information as model input and / or model selection.

[0153] Continuing to refer to FIG. 2, in some embodiments, the method shown in FIG. 2 can further include step S230. In step S230, the second device adds or modifies a local configuration of the second device according to the first information.

[0154] In some embodiments, the purpose of the second device adding or modifying the local configuration of the second device according to the first information is to store the first information locally in the second device for later use. However, embodiments of the present application are not limited thereto, in some embodiments, the second device can use the first information as model input or model selection information only once after receiving the first information.

[0155] In some embodiments, the local configuration of the second device can include information of the first device. For example, the local configuration of the second device can include the first information of the first device. That is, the local configuration of the second device can store the first information of the first device. However, the embodiments of the present application are not limited thereto, and in some embodiments, the local configuration of the second device can also include other information in addition to the first information of the first device. For example, the local configuration of the second device can also include the identity of the first device, the signal quality of the first device, and the like.

[0156] In some embodiments, when the local configuration of the second device does not store the first information, the second device can add the first information to the local configuration of the second device.

[0157] In some embodiments, when the local configuration of the second device stores the first information, the second device can add the first information to the local configuration of the second device or modify the local configuration of the second device according to the first information.

[0158] For example, when the local configuration of the second device allows multiple groups of first information to coexist, the second device can add the first information to the local configuration of the second device. As an example, the local configuration of the second device allows multiple groups of first information to coexist, and the local configuration of the second device previously only includes the position information of the first device. When the first information sent by the first device includes the speed information of the first device, the second device can add the speed information of the first device to the local configuration of the second device.

[0159] For another example, when the local configuration of the second device stores the first information, after the second device receives the first information, the second device can replace (completely modify) the first information stored in the local configuration of the second device with the received first information. As an example, the local configuration of the second device previously stores the speed information of the first device, and the first information received by the second device also includes the speed information of the first device. The second device can replace the speed information of the first device stored in the local configuration with the received speed information of the first device.

[0160] For example, when the local configuration of the second device stores the first information, and the second device receives the first information, the received first information partially overlaps with the first information stored in the local configuration, in this case, the second device can use the received first information to partially modify the first information stored in the local configuration of the second device. As an example, the local configuration of the second device previously stores the speed information and the acceleration information of the first device, and the second device receives the first information containing the position information and the speed information of the first device (partially or entirely the same as the speed information stored in the local configuration), then the second device can partially modify according to the first information, for example, the modified local configuration includes the position information, the speed information and the acceleration information of the first device, wherein the speed information is the same as the speed information in the received first information. As another example, the local configuration of the second device previously stores the reference information of the speed information of the first device, and the second device receives the first information containing the incremental information of the speed of the first device, then the second device can determine the speed information of the first device according to the reference information and the incremental information, and modify.

[0161] In some embodiments, the purpose of storing the first information of the first device in the local configuration of the second device is to run a model using the first information, such as model training, model inference, etc.
