The terminal device in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, and may be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiment of the present application can be a mobile phone, a tablet computer, a laptop, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity, which provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D). For example, a cellular phone and a car communicate with each other using a sidelink signal. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0029] The network device in the embodiment of the present application refers to a device used to communicate with a terminal device, for example, including an access network device (AN) and / or a core network device (or core network element). Among them, the access network device can be an access device that the terminal device accesses to the network architecture by wireless means, and is mainly responsible for wireless resource management, quality of service (QoS) management, data compression and encryption, etc. on the air interface side. The access network device can also be called a radio access network (RAN) device, for example, the access network device can be a base station. Base station can broadly cover various names as follows, or replace with the following names: NodeB, evolved NodeB (eNB), next generation NodeB (gNB), relay station, access point, transmission point (TRP), transmission point (TP), home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof.

[0031] In addition, in 5G NR, a network data analytics function (NWDAF) is added to the core network. Based on NWDAF, data can be collected from various network elements and network management systems in the core network, and big data statistics, analysis or intelligent data analysis can be performed to obtain analysis or prediction data on the network side, thereby assisting various network elements to more effectively control the access of terminal devices based on the data analysis results.

[0032] In the 5G NR network, the core network element can also be called a network function (NF).

[0033] AI / ML Models

[0034] In the 3rd Generation Partnership Project (3GPP) in release 18 (Rel 18 / R18), the question of whether artificial intelligence (AI) / machine learning (ML) models (or AL / ML algorithms, AL / ML functions) can help improve the performance of the physical layer was studied. 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, this technical report also records the steps and contents of how to manage AI / ML models on the network device side, the terminal device side, or both the network device and the terminal device. These related contents constitute the content of life cycle management (LCM) in this technical report. It should be noted that LCM is a relatively broad term, and its contents include, for example: data collection; model training; function / model identification; model transmission; model reasoning; function / model selection, activation, deactivation, replacement and fallback; function / model monitoring; model update; terminal device capability reporting, etc.

[0035] 3GPP has determined to introduce AI / ML models in multiple technical directions, such as for beam management and mobility management. For beam management, for example, the AL / ML model can be applied to prediction in the spatial domain, that is, by measuring a subset of beams in a set and using the spatial correlation between beams, the best beam in the full set of beams (for example, the beam with the strongest wireless signal) is predicted. The best beam may include one beam, or may include a pair of beams, one for downlink transmission and one for reception. For another example, the AL / ML model is applied to beam prediction in the time domain, that is, based on the measurement results of the measured beams and / or the predicted beams in the historical time, the correlation of the beams in time is used to predict the measurement results of the beams in the current time slot. Judging from the recorded evaluation results, the beam prediction of the AI / ML model in the spatial and time domains is not only technically feasible, but also can bring higher performance improvements.

[0036] For downlink data transmission, Figure 2 and Figure 3 The flow charts of the traditional mechanism and the mechanism after the introduction of the model are shown respectively. In the traditional mechanism before the introduction of the model, Figure 2As shown, in step 210, the network device sends a reference signal to the terminal device; in step 220, the terminal device sends the measurement result of the reference signal to the network device; in step 230, the network device determines the beam to be used for the next downlink data transmission based on the measurement result reported by the terminal device; in step 240, the network device sends downlink data to the terminal device based on the beam. Since the beam changes very quickly, the network device needs to send reference signals frequently, and the terminal device needs to report measurement results frequently. After the introduction of the model, as shown in FIG. Figure 3 As shown, in step 310, the network device sends a reference signal (for example, a small amount of reference signals) to the terminal device; in step 320, the terminal device performs model prediction based on the measurement results of the small amount of reference signals; in step 330, the terminal device reports the model prediction results to the network device; in step 340, the network device determines the beam used for the next downlink data transmission based on the model and the content reported by the terminal device; in step 350, the network device sends downlink data to the terminal device based on the beam. After the model is introduced, the terminal device and the network device are both deployed with the model. The terminal device measures the small amount of reference signals sent by the network device as the input of its own model. After the model of the terminal device is run, some intermediate information is generated and reported to the network device. The model of the network device uses the intermediate information reported by the terminal device, and then combines other information and runs its model to determine the beam for downlink transmission. These intermediate information are the outputs obtained after the model of the terminal device predicts the measurement results, and are also referred to as model prediction results below.

[0037] Similarly, for uplink data transmission, the model of the terminal device can also predict the measurement results of the uplink beam, generate intermediate information and report it to the network device. The network device uses this intermediate information and inputs its own model to ultimately predict which uplink beams have the best transmission performance and notify the terminal device to use these beams to transmit data.

[0038] Minimizing driving test (MDT)

[0039] In the existing 3GPP specifications, MDT technology is used to collect relevant information from terminal devices to reduce the workload of route testing in network planning. The MDT process is for the terminal device and network equipment to collect some information, such as switching failures, number of random access attempts, actual data transmission delay, etc., for the network management system to use for network optimization. In MDT, what information the terminal device needs to measure as MDT information and how to report it are all configured by the network equipment. The terminal device collects measurement information according to the MDT configuration sent by the network device, and reports it according to the reporting type and conditions configured by the network device. It can be roughly divided into two MDT reporting methods, immediate MDT and logged MDT. Usually, immediate MDT is used to report emergency content, and other content is reported to the network device through the MDT log. For example, if Figure 4 In the MDT process shown in FIG. 4 , in step 410, the network device sends the MDT configuration to the terminal device; in step 420, the terminal device reports the MDT based on the MDT configuration; wherein step 420 is a reporting method of the instant MDT. Figure 4 In step 430, the network device sends a notification to the terminal device requesting the terminal device to report the MDT result; in step 440, the terminal device reports the MDT to the network device; in step 450, the terminal device reports the MDT to the network device; wherein steps 430 to 450 are the reporting method of log MDT. In the reporting method of log MDT, the reporting of the MDT result is triggered by the network device. After receiving the notification sent by the network device, the terminal device reports the MDT result stored in the MDT cache to the network device through an RRC message. If there are too many contents in the cache and one RRC message cannot report all, multiple RRC messages are used for reporting. The terminal device can indicate to the network device in the reported RRC message that "there is still data to be reported". When the terminal device reports the MDT, it can follow the first-in-first-out principle, for example, the MDT information generated earlier is reported first. If the MDT information is stored in the MDT cache for more than 48 hours, the terminal device deletes the information. If the network device triggers the terminal device to report MDT, and there is no information in the MDT cache of the terminal device, the terminal device reports "MDT empty".

[0040] The reporting of model prediction results can refer to the above-mentioned MDT process. However, since the purpose of MDT is to collect information for network optimization, the reporting of log MDT has the following characteristics: reporting is not urgent, in which the reporting is initiated by the network device, and the terminal device does not actively initiate it. Even if the MDT cache of the terminal device is full, it does not actively initiate reporting; the importance of MDT information measured in each time period is the same, in which, when the terminal device reports MDT information, the first measured information is reported first, and then the latest measured information is reported; the cache is full and discarded, that is, if the MDT cache of the terminal device is full, the latest measurement information is no longer stored. However, these characteristics are not applicable to the reporting of model measurement results. If the model prediction results of the terminal device cannot be reported to the network device in time, the model of the network device cannot accurately predict the beam. If an inappropriate beam transmission is scheduled, a transmission failure may occur, reducing the transmission efficiency. In addition, the model prediction results obtained by the terminal device in each time period have different importance. Since the beam changes very quickly, the model of the terminal device predicts according to the latest beam situation. The newer the model prediction results, the more important they are to the network device. In addition, if the terminal device discards the new model prediction result without reporting it when the cache is full, it will seriously affect the accuracy of the beam prediction of the model of the network device. Therefore, the embodiment of the present application proposes to use a mechanism similar to the MDT process to report the model prediction result, and in order to be more suitable for the reporting requirements of the model prediction result, corresponding improvements are made on the basis of the MDT process.

[0041] To this end, in the embodiment of the present application, the terminal device sends a first message to the network device to request the reporting of the second information, and the second information includes the model prediction result, so that the network device can obtain the reporting requirements of the terminal device in a timely manner, which is conducive to the effective reporting of the model prediction result. Unlike the MDT report that can only be initiated by the network device, the reporting of the model prediction result in the embodiment of the present application can be initiated by the terminal device. The terminal device informs the network device through the first information that it has the second information to be reported, so that the network device can arrange the terminal device to report the model prediction result in a timely manner.

[0042] Combine the following Figure 5 , the embodiments of the present application are introduced in detail.

[0043] Figure 5 A flowchart of a wireless communication method provided in an embodiment of the present application. Figure 5 The method 500 shown can be performed by a terminal device and a network device. The terminal device can be, for example, Figure 1 The terminal device 120 shown in FIG. 1 , the network device may be, for example, Figure 1 The network device 110 shown in FIG.

[0044] See also Figure 5 In step 510, the terminal device sends first information to the network device; accordingly, in step 520, the network device receives the first information sent by the terminal device.

[0045] Among them, the first information is used to request reporting of the second information. Optionally, the second information may include a model prediction result. Alternatively, the second information may also include auxiliary information for model training, which can help the network device train the model of the network device. The following is an example of the model prediction result. The model described in the embodiment of the present application may be, for example, an AI model or an ML model, and the model may also be referred to as a module or a function.

[0046] The first information can be carried, for example, in a non-access stratum (NAS) message, or in a radio resource control (RRC) message, or in a medium access control control element (MAC CE), or in a physical uplink control channel (PUCCH).

[0047] Optionally, the second information may also include the collection time of the model prediction results. The collection time may be, for example, the absolute time of collecting the model prediction results; and / or the time difference between the moment of collecting the model prediction results and the moment of sending the second information. The collection time may be the time when the terminal device collects the model prediction results, or the time when the network device requires the terminal device to collect the model prediction results. The collection time is usually later than the actual generation time of the model measurement results (i.e., the time when the model measurement results are generated inside the terminal device). Taking the MDT process as an example, for the instant MDT method, the collection time is the time when the terminal device reports the measurement results. For the log MDT method, the collection time is the time when the terminal device records or stores the measurement results.

[0048] In some implementations, in step 510, the terminal device sends first information to the network device when the first condition is met. The first condition may be pre-agreed; or, the network device may send information of the first condition to the terminal device. If the first condition is obtained from the network device, as an example, the first condition may be obtained from the core network device (for example, obtained through a NAS message); or, the first condition may be obtained from the access network device (for example, obtained through an RRC message or a MAC CE); or, the first condition may be obtained from a network management platform; or, the first condition may be obtained from an application server.

[0049] If the first condition is pre-agreed, as an example, the first condition may be associated with one or more of the following: the type of terminal device; the type of model of the terminal device; the type of cache in the terminal device for storing the second information; the size of the cache. Among them, the type of terminal device can be distinguished, for example, by hardware configuration (for example, antenna size, antenna angle, antenna height, etc.) and / or software configuration (for example, software program, data, etc.), and the first conditions used by different types of terminal devices may be different. The type of model can be distinguished based on different prediction functions, or based on different reasoning accuracies and / or different application conditions under the same prediction function. For example, the model that implements the spatial domain prediction function of the beam measurement result is used as a model type, and the model that implements the time domain prediction function of the beam measurement result is used as another model type; for another example, there may be models applied to different scenarios under the same prediction function. Taking the spatial domain prediction function of the beam measurement result as an example, there is a scenario in which the measurement results of 8 beams are obtained based on the measurement results of 4 beams, and there is also a scenario in which the measurement results of 32 beams are obtained based on the measurement results of 8 beams. The former can be regarded as a model type, and the latter can be regarded as another model type.

[0050] In some implementations, the first condition may include one or more of the following: the occupancy rate of the cache used to store the second information in the terminal device exceeds the first threshold; the amount of data of the second information stored in the cache exceeds the second threshold; the second information stored in the cache includes second information with a priority higher than a third threshold; the second information stored in the cache includes second information whose time difference between the timeout moment and the current moment is less than a fourth threshold; the timer associated with the reporting of the second information in the terminal device times out.

[0051] Among them, the cache used to store the second information in the terminal device may refer to a dedicated cache used to store the model and the model prediction result and related information thereof, or may refer to the entire cache in the terminal device. The first condition may be associated with the amount of data in the cache. For example, the first condition may be that the occupancy rate of the cache exceeds the first threshold (for example, 30%, 50%, 100%, etc.), or the amount of data of the model prediction result to be reported stored in the cache exceeds the second threshold (for example, more than M bits). The first condition may also be associated with the priority of the data in the cache. For example, the first condition may be that a model prediction result with a priority higher than the third threshold appears in the cache. Here, the priority of the data may be pre-agreed. For example, if the deviation between the model prediction result of a beam and its historical prediction result is too large and exceeds a certain threshold, it indicates that there may be a deviation between the model prediction result and the actual measurement result, and the model accuracy may be decreasing. Therefore, the priority of the model prediction result of the beam is higher. The first condition may also be associated with the data storage time in the cache. For example, the first condition may be that the model prediction result stored in the cache is about to time out (for example, there is still a Y second timeout), or the timer associated with the report has timed out. The timer may be started when the second information is sent to the network device last time, and the timing duration of the timer may be pre-agreed or configured by the network device, for example. The duration of the timer started each time the report is made may be the same or different. Optionally, when the first condition is met, the first information may be sent immediately, or the first information may be sent at the end of a predetermined duration after the moment when the first condition is met.

[0052] As an example, as shown in Table 1, it is assumed that the model type includes model type 1 and model type 2, model type 1 is a model that implements the spatial domain prediction function of the beam measurement result, model type 2 is a model that implements the time domain prediction function of the beam measurement result, the first condition associated with model type 1 is condition 1, and the first condition associated with model type 2 is condition 2, condition 1 is that the amount of stored data is greater than 200 bits, and condition 2 is that the cache occupancy rate exceeds 50%. If the terminal device sends a first message to the network device to request to report the model prediction result of model type 1, it is necessary to determine when to send the first information based on condition 1, for example, when the amount of cached data is greater than 200 bits; if the terminal device sends a first message to the network device to request to report the model prediction result of model type 2, it is necessary to determine when to send the first information based on condition 2, for example, when the cache occupancy rate exceeds 50%.

[0053] Table 1

[0054] Model Type condition Model type 1: Beam measurement result spatial prediction function Condition 1: The data volume is greater than 200 bits Model type 2: Beam measurement result time domain prediction function Condition 2: The cache occupancy rate exceeds 50%

[0055] For another example, as shown in Table 2, it is assumed that the types of terminal devices include device type 1, device type 2, and device type 3, the first condition associated with device type 1 is condition 1, the first condition associated with device type 2 is condition 2, and the first condition associated with device type 3 is condition 3, condition 1 is the presence of data with a priority exceeding level X, condition 2 is the cache occupancy rate exceeding 50%, and condition 3 is the presence of data with a priority exceeding level X and the amount of data with a priority exceeding level X is greater than 200 bits. If the type of the terminal device is device type 1, the terminal device determines when to send the first information based on condition 1, for example, sending the first information when the cache includes data with a priority exceeding level X; if the type of the terminal device is device type 2, the terminal device determines when to send the first information based on condition 2, for example, sending the first information when the cache occupancy rate exceeds 50%; if the type of the terminal device is device type 3, the terminal device determines when to send the first information based on condition 2, for example, sending the first information when the cache includes data with a priority exceeding level X and the amount of data with a priority exceeding level X is greater than 200 bits.

[0058]

[0059] In some implementations, the first information may include one or more of the following: indication information for indicating that the network device triggers reporting of the second information; the amount of data in the cache for storing the second information in the terminal device; the remaining storage space in the cache; the percentage of the capacity of the cache occupied by the cached second information; the storage time of the longest (or oldest) second information stored in the cache; the time required for the cache to be full; the priority of the second information with the highest priority in the cache. The indication information may be, for example, a Boolean variable, which, if set to TRUE, indicates that the network device is required to trigger reporting of the second information; the indication information may also be an enumeration variable, which indicates that the network device is required to trigger reporting of the second information as long as the indication information exists.

[0060] In some implementations, the network device sends the third information to the terminal device; accordingly, the terminal device receives the third information sent by the network device. The third information indicates that the terminal device reports the second information. Specifically, after receiving the first information, the network device can determine whether to send the third information to the terminal device based on the content carried in the first information. Optionally, after the terminal device sends the first information to the network device, if the terminal device waits for a period of time and still does not receive the third information sent by the network device, the terminal device can send the first information to the network device again. Here, the period of time that the terminal device waits can be configured or agreed in advance by the network device (for example, an access network device or a core network device).

[0061] The third information may be carried in an RRC message, or the third information may be carried in a MAC CE, or the third information may be carried in downlink control information (DCI). Taking the RRC message as an example, the RRC message may be a terminal device information request (UEInformationRequest) message. Specifically, the network device may carry the third information in the UEInformationRequest message. For example, as shown below, a parameter is added to the UEInformationRequest message (for example, parameters such as AI PredictionReq-R19 or AI Request-R19) to indicate that the network device requires the terminal device to report the second information. The parameter may be a Boolean variable. If it is set to TRUE, it indicates that the network device is required to trigger the reporting of the second information. The indication information may also be an enumeration variable. As long as the indication information exists, it indicates that the network device is required to trigger the reporting of the second information. An example of a UEInformationRequest message is shown below:

[0073] In addition to being used to indicate that the terminal device reports the second information, the third information can also further limit the second information reported by the terminal device. For example, in some implementations, the third information is also used to indicate one or more of the following: reporting all cached second information; reporting the second information with the first bit quantity (e.g., N1 bits) with the most recent (or latest) storage time; reporting the second information with the second bit quantity (e.g., N2 bits) with the longest (or oldest) storage time; reporting the second information obtained within the first time duration (e.g., K1 seconds) with the most recent storage time; reporting the second information obtained within the second time duration (e.g., K2 seconds) with the longest storage time; reporting the second information obtained between the first moment (e.g., T1) and the second moment (e.g., T2), the first moment and the second moment can be relative times or the time difference relative to the current moment; reporting the second information with a predetermined priority (e.g., priority level S1); reporting the second information with a priority higher than the fifth threshold (e.g., higher than level S2); reporting the second information with a priority lower than the sixth threshold (e.g., lower than level S3).

[0074] In some implementations, the terminal device may send the second information to the network device; accordingly, the network device receives the second information sent by the terminal device. After receiving the third information, the terminal device selects the corresponding second information from the cache for reporting based on the indication of the third information. The second information may be carried, for example, by an RRC message. As an example, the RRC message may be a terminal device information response (UEInformationResponse) message.

[0075] The second information can be carried by one or more RRC messages. If the data volume of the second information exceeds the maximum data volume carried by one RRC signaling, the second information can be reported through multiple RRC messages. At this time, the terminal device can indicate the status of other subsequent RRC messages in the previous RRC message, such as indicating "there is more second information that needs to be reported", "how many bits of second information need to be reported", or "how many RRC messages need to be reported". After receiving the RRC message, the network device continues to allocate uplink wireless resources to the terminal device.

[0076] In some implementations, the network device may also send fourth information to the terminal device; accordingly, the terminal device receives the fourth information sent by the network device. The fourth information is used to instruct the terminal device to process the second information. That is, after receiving the first information, the network device may send the fourth information to the terminal device in addition to sending the third information to instruct it how to report the second information, to instruct it to process the second information. For example, processing the second information may include one or more of the following: deleting the second information obtained before the third duration (for example, V seconds), wherein the third duration may be an absolute duration or a time difference relative to the current time; deleting the second information with a priority higher than the seventh threshold (for example, higher than the Q1 level); deleting the second information with a priority lower than the eighth threshold (for example, lower than the Q2 level); deleting other second information other than the target second information. The target second information is the second information reported by the terminal device, that is, the terminal device receives the third information of the network device, and the third information indicates that the second information reported by the terminal device is the target second information. When the terminal device sends the target second information to the network device, it will delete other second information that is not reported in the cache.

[0077] The fourth information can be sent to the terminal device together with the third information. For example, the fourth information and the third information are carried in the same message (for example, RRC message, MAC CE or DCI) and sent to the terminal device; or, the fourth information and the third information are carried in different messages and sent to the terminal device.

[0078] When reporting the second information, the terminal device may be based on certain rules, which may be configured by the network device (for example, the information of the rule is carried in the third information or the fourth information) or pre-agreed (for example, stipulated by the protocol). For example, the second information is reported based on the first-in-first-out rule; the second information is reported based on the last-in-first-out rule; the second information is reported based on the order of priority from high to low. Among them, the first-in-first-out reporting rule can make the data with a longer storage time reported as soon as possible. For example, the second information includes data 1, data 2 and data 3 received in sequence in time, that is, the storage time of data 1 is greater than the storage time of data 2, and the storage time of data 2 is greater than the storage time of data 3. Then, when reporting, data 1 is reported first, then data 2, and finally data 3. For the last-in-first-out reporting rule, the importance of the second information collected by the terminal device in each time period is different. Since the beam changes very quickly, the model of the terminal device makes predictions based on the latest beam situation, so the latest collected data may be more important to the network device. Therefore, the last-in-first-out rule can make this part of the data reported to the network device as soon as possible.

[0079] It can be seen that based on the technical solution of the embodiment of the present application, the terminal device can promptly notify the network device that there is model prediction data to be reported, and the network device can effectively control the reporting of the model prediction data according to demand.

[0080] It should be noted that in other technical solutions provided by the embodiments of the present application, the terminal device may not send the first information to the network device, but instead report the second information to the network device after receiving the third information sent by the network device. In other words, the transmission of the third information and the reporting of the second information may not depend on the first information. For example, taking the second information including auxiliary information as an example, the terminal device receives the third information sent by the network device, and the third information instructs the terminal device to report the second information. At this time, the terminal device sends the second information, i.e., the auxiliary information, to the network device.
