[0061] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.
[0062] First embodiment: UE reports first predicted measurement information predicted by UE based on AI / ML model
[0063] FIG2A is a flow chart of a wireless communication method provided in an embodiment of the present application. As shown in FIG2A , the wireless communication method is executed on a user equipment (UE) and includes at least one of the following operations: Operation 201: Sending first predicted measurement information of the UE based on an artificial intelligence / machine learning AI / ML model prediction to at least one network node through a first message. The first predicted measurement information is the mobility information of the UE at a future time, and the mobility information of the UE at a future time includes at least one of the following information: AI / ML model identification information, switching node identification information, switching node access resource information, switching node access resource validity information, switching node access resource prediction accuracy information, predicted measurement results, predicted additional measurement results, predicted adjacent cell switching beam, predicted measurement result time, and / or accuracy.
[0064] FIG2B is a flow chart of a wireless communication method provided in an embodiment of the present application. As shown in FIG2B , the wireless communication method is executed on at least one network node and includes at least one of the following operations: Operation 202: Receive first predicted measurement information of the UE based on an artificial intelligence / machine learning AI / ML model predicted by the user equipment UE through a first message. The first predicted measurement information is the mobility information of the UE at a future time, and the mobility information of the UE at a future time includes at least one of the following information: AI / ML model identification information, switching node identification information, switching node access resource information, switching node access resource validity information, switching node access resource prediction accuracy information, predicted measurement results, predicted additional measurement results, predicted adjacent cell switching beam, predicted measurement result time, and / or accuracy.
[0065] Specifically, the UE is, for example, user equipment 120 shown in Figure 1 . At least one network node is, for example, base station 110 and / or network 130 (first network node) shown in Figure 1 . Base station 110 is, for example, a gNB. For example, in some embodiments of the present invention, the UE sends first predicted measurement information, predicted by the UE based on an artificial intelligence / machine learning (AI / ML) model, to at least one network node. This first predicted measurement information is used to represent relevant information about a target handover node within a future period of time. In this way, the movement trajectory of the user equipment 120 can be predicted using the AI / ML algorithm, thereby better allocating radio resources and mobility management for the user equipment 120. This can also solve conventional technical problems. Conventional technical problems, for example, are that existing radio resource management (RRM) measurement results do not support measurement reporting at future times. The UE predicts possible RRM measurement results at a certain point in the future based on historical information, which can generate misleading information. Furthermore, in traditional handovers, handover delays can occur.
[0066] In some embodiments of the present invention, the first message includes radio resource management (RRM) signaling, radio resource control (RRC) signaling or UE assistance information.
[0067] Specifically, in some embodiments of the present invention, the UE may send first predicted measurement information based on the AI / ML model prediction of the UE to at least one network node via RRM signaling. In some embodiments of the present invention, the UE may send first predicted measurement information based on the AI / ML model prediction of the UE to at least one network node via RRC signaling. In some embodiments of the present invention, the UE may send first predicted measurement information based on the AI / ML model prediction of the UE to at least one network node via UE assistance information. The RRC signaling is, for example, an RRC-specific predicted RRM reporting message.
[0068] In some embodiments of the present invention, the AI / ML model identification information is used to indicate the AI / ML model used by the UE, and the AI / ML model identification information includes at least one of the following information: model ID, functional ID, feature ID, and / or RRC configuration ID.
[0069] In some embodiments of the present invention, the switching node identification information is used to indicate identification information of the switching node, and the switching node identification information includes at least one of the following information: area ID, cell ID, sending and receiving point TRP ID, and / or tracking area TA.
[0070] In some embodiments of the present invention, the handover node access resource information indicates resource information used by the handover node for handover or access in the future. The handover node access resource information includes pilot signal period, time interval, frequency domain location, density information, transmission duration, and / or transmission power. Specifically, in some embodiments of the present invention, the resource includes at least one of a beam, a spectrum, and a bandwidth. Additionally, the resource information may further include pilot configuration information requirements for data transmission or measurement after the handover. The expression of the future period of time is similar to, but not limited to, the handover node access resource validity information. In some embodiments of the present invention, the resource information in the handover node access resource information may further include pilot configuration information requirements for data transmission or measurement after the handover, including at least one of pilot signal period, time interval, frequency domain location, density information, transmission duration, and transmission power. This information is used to guide the pilot transmission strategy of the target handover node to better help the target node serve the current UE during data transmission or handover, thereby reducing the probability of handover failure or providing higher data transmission capacity after the handover is completed.
[0071] In some embodiments of the present invention, the handover node access resource validity information is used to indicate the handover node access resource corresponding to the handover node, or the validity period or validity area of the handover node. Specifically, in some embodiments of the present invention, the validity information may be a time description, including one or more of a start time, an end time, and a duration. Furthermore, the validity information may also be expressed as a coverage range, such as a TA; as a UE trajectory range; or in other ways.
[0072] In some embodiments of the present invention, the switching node access resource validity information includes a first implementation method or a second implementation method, wherein the first implementation method refers to an access resource validity information corresponding to each access resource, which is used to characterize the effective time of each access resource, and the second implementation method refers to the order of the access resources used to represent the effective time sequence of the access resources, as well as the corresponding time interval. Specifically, in some embodiments of the present invention, in order to further reduce the configuration overhead, and taking into account that the measurement resources (CSI-RS or SSB, etc.) are in a periodic transmission state, the implementation method of the node access resource validity message includes two implementation methods. As described below.
[0073] First implementation: Direct representation: In this solution, each access resource is associated with access resource validity information, which represents the effective time of the resource. For example, {(Beam 1, time 1), (Beam 2, time 2)} indicates that the time corresponding to Beam 1 is time 1, and the effective time corresponding to Beam 2 is time 2.
[0074] Second implementation: Sequential representation: In this solution, the order of access resources represents the order in which they become effective, along with the corresponding time intervals. For example, {Beam 1, Beam 2, Beam 3} indicates that Beam 1 is available at time T0, Beam 2 at time T0+DeltaT, and Beam 2 at time T0+2*DeltaT. DeltaT can be predefined or configured for the UE by the base station.
[0075] In some embodiments of the present invention, the switching node access resource prediction accuracy information is used to represent the access resources corresponding to the switching node or the prediction accuracy of the switching node.
[0076] In some embodiments of the present invention, the switching node access resource prediction accuracy information includes a first mode, a second mode, or a third mode. The first mode means that all switching node access resources share one accuracy, the second mode means that each switching node access resource corresponds to one accuracy, and the third mode means that one or more of all switching node access resources share one accuracy. Specifically, in some embodiments of the present invention, for the switching node access resource prediction accuracy information, its expression can be three modes. One mode is that all switching node access resources share one accuracy, that is, the accuracy corresponding to all switching node access resources. The second mode is that each switching node access resource corresponds to a separate accuracy. The third mode is that one or more of all switching node access resources share one accuracy. The three accuracy modes provided can greatly reduce the feedback overhead and provide relatively high flexibility for the implementation of AI / ML on the UE side. For example, the acquisition of switching node access resources can be obtained by one AI / ML model or by different AI / ML models.
[0077] In some embodiments of the present invention, the above information representation is illustrated by way of example: {AI Model #1, Cell #1, Beam #1, Time window #1, 90%} indicates that when AI Model #1 is used, the accuracy of Beam #1 corresponding to Cell #1 during Time window #1 is 90%; and {AI Model #1, Cell #1, Time window #1, 90%} indicates that when AI Model #1 is used, the accuracy of Cell #1 during Time window #1 is 90%. Other examples are not described further here.
[0078] In some embodiments of the present invention, the UE identification information is used to identify which UE the information belongs to. In some embodiments of the present invention, the UE identification information is a user globally unique identifier or a radio network terminal identifier (RNTI) information.
[0079] In some embodiments of the present invention, the predicted measurement result refers to a measurement result predicted by the UE based on an AI / ML model.
[0080] In some embodiments of the present invention, the predicted additional measurement result refers to the UE's measurement result of the beam when the serving cell is not configured for beam measurement. Specifically, in some embodiments of the present invention, serving cell 1 may not be configured for beam 2 measurement. In this case, the UE may include the measurement result of beam 2 in the first predicted measurement information and report it to at least one network node, predicting that beam 2 is the beam to be switched and reporting it to serving cell 1.
[0081] In some embodiments of the present invention, the predicted neighboring cell handover beam refers to the beam expected to be used after the neighboring cell is switched. In some embodiments of the present invention, the predicted measurement result time refers to the time range of the expected measurement result, and the predicted measurement result time is an absolute time or a relative time. In some embodiments of the present invention, the predicted measurement result time includes at least one of the following times: the predicted measurement result time range start time, the predicted measurement result time range end time, and / or the valid time window.
[0082] Specifically, in some embodiments of the present invention, the predicted measurement result time includes the start time of the time range of the expected measurement result, which can be an absolute time or a delta relative to the current time. The predicted measurement result time includes the end time of the time range of the expected measurement result. The predicted measurement result time includes a valid time window.
[0083] In some embodiments of the present invention, the predicted measurement result accuracy refers to a measurement error range of the Reference Signal Received Power (RSRP) of the expected measurement result or a measurement error range of the time of the expected measurement result. Specifically, in some embodiments of the present invention, the predicted measurement result accuracy may be an RSRP error of 10%, 20%, or a time error of 1s, 2s, or so on.
[0084] In some embodiments of the present invention, the UE assists the at least one network node with configuration via UE assistance information. Specifically, in some embodiments of the present invention, the UE may also assist the at least one network node with configuration of measurement reporting via UE assistance information-assisted / (predicted) measurement configuration. Preferably, the measurement configuration includes which SSBs of which neighboring cells are measured. In other words, the predicted neighboring cell beam switching is reported in the UE assistance information, rather than in the first predicted measurement information.
[0085] The UE assists the at least one network node in configuring the information element (IE) for measurement reporting through the UE assistance information. The example is as follows: UEAssistanceInformation-v1910-IEs::=SEQUENCE{ preferredMeasconfig preferredPredictedMeasconfig}
[0086] Example: gNB configures UE to report predicted RRM measurement report conditions

Operation 205: Send the first predicted measurement information predicted by the UE based on an artificial intelligence / machine learning (AI / ML) model to at least one network node through a first message. The first predicted measurement information is the mobility parameter of the UE at a future moment, and the first predicted measurement information includes at least one of the following parameters: UE identification information, predicted measurement results, predicted additional measurement results, predicted adjacent cell switching beams, predicted measurement result time, and / or predicted measurement result accuracy.
[0089] Specifically, the UE is, for example, the user equipment 120 shown in Figure 1. The at least one network node is, for example, the base station 110 and / or the network 130 (first network node) shown in Figure 1. The base station 110 is, for example, a gNB.
[0090] Illustratively, in some embodiments of the present invention, the UE sends first predicted measurement information predicted by the UE based on an artificial intelligence / machine learning (AI / ML) model to at least one network node, and the first predicted measurement information is used to express relevant information of the target switching node within a period of time in the future. In this way, the movement trajectory of the user equipment 120 can be predicted through the AI / ML algorithm, so as to better allocate wireless resources and mobility management for the user equipment 120. This can also solve conventional technical problems. Conventional technical problems are, for example, that existing radio resource management (RRM) measurement results do not support measurement reporting at future times. The UE will predict possible RRM measurement results at a certain point in the future based on historical information, which will generate misleading information. In addition, in traditional switching, there is a problem of switching delay.
[0091] In some embodiments of the present invention, before sending the first predicted measurement information predicted by the UE based on the AI / ML model to the at least one network node through the first message, the method includes: receiving a prediction configuration sent by the at least one network node.
[0092] In some embodiments of the present invention, the prediction configuration includes a trigger condition, where the trigger condition is a condition that triggers the UE to send the first predicted measurement information to the at least one network node, and the trigger condition includes at least one of the following: a predicted measurement event, a predicted measurement time, a predicted measurement advance time, and / or a current measurement result. In some embodiments of the present invention, if the prediction configuration is at the beam level, the first predicted measurement information is also at the beam level.
[0093] Specifically, in some embodiments of the present invention, to support UE-side mobility handover measurements, the base station needs to configure an RRM measurement reporting event for the UE to minimize UE feedback overhead while ensuring real-time measurement time. After the introduction of AI / ML-based predicted RRM measurement reporting, the configuration information for predictive RRM measurements on the UE includes at least one or more of the following information.
[0094] Predicted Measurement Event: This is a prediction-based measurement event definition that describes the measurement reporting process performed by the UE upon detecting the measurement event. Detailed implementation details are described below.
[0095] Predicted measurement time: This indicates the duration for which the predicted measurement event needs to occur, and then reports the predicted measurement results. This time can be expressed as one or more of the following: start time, end time, minimum measurement time window, maximum measurement time window, or measurement duration window.
[0096] Predicted measurement lead time: Indicates how long in advance a predicted measurement event is detected before a predicted measurement report is submitted. This time can be expressed in absolute or relative terms.
[0097] The current measurement result is used as a trigger for predictive RRM measurement: The current measurement result may indicate the current location of the UE, for example, the UE has moved close to the cell edge. Therefore, the current measurement result can be used as a trigger for predictive RRM measurement.
[0098] In some embodiments of the present invention, the predicted measurement configuration can be at the cell level or the beam level. If the measurement configuration is at the beam level, the predicted measurement report is also at the beam level (SSB-INDEX).
[0099] To illustrate the above method, an example is provided here, but this example is not intended to limit other implementations of this solution. For example, if the gNB configures a predictive measurement configuration (predicted measurement event A3, start time 10s, end time 20s), the UE reports the predicted measurement event when it predicts that the A3 measurement event will occur 10-20 seconds in advance. For example, if the gNB configures a predictive measurement configuration (predicted measurement event A3, time advance 10s), the UE reports the predicted measurement event when it predicts that the A3 measurement event will occur 10 seconds in advance.

Exemplarily, in some embodiments of the present invention, the UE sends predicted measurement capability information to the at least one network node. In this way, the movement trajectory of the user equipment 120 can be predicted through the AI / ML algorithm, so as to better allocate wireless resources and mobility management to the user equipment 120. This can also solve conventional technical problems. Conventional technical problems are, for example, that existing radio resource management (RRM) measurement results do not support measurement reporting at future times. The UE will predict the possible RRM measurement results at a certain point in the future based on historical information, which will generate misleading information. In addition, in traditional switching, there will be a problem of switching delay.
[0105] In some embodiments of the present invention, before receiving the prediction configuration sent by the at least one network node, the method includes: sending predicted measurement capability information to the at least one network node, wherein the predicted measurement capability information includes at least one of the following information: handover failure prediction support, radio link failure prediction support, cell-level RRM prediction support, beam-level RRM prediction support, cell-level handover prediction support, and / or beam-level handover prediction support.
[0106] In some embodiments of the present invention, before sending the predicted measurement capability information to the at least one network node, the method includes: receiving a predicted measurement capability request sent by the at least one network node. In some embodiments of the present invention, the predicted measurement capability request is used to request the UE to report RRM predicted capabilities.
[0107] In some embodiments of the present invention, the handover failure prediction support refers to the UE's ability to support handover failure prediction, including whether it supports the ability to predict when the UE will experience a handover failure, and the handover failure prediction support includes node information and / or resource information and / or AI / ML model information. In some embodiments of the present invention, the radio link failure prediction support refers to the UE's ability to support radio link failure prediction, including whether it supports the ability to predict when the UE will experience a radio link failure, and the radio link failure prediction support includes node information and / or resource information and / or AI / ML model information.

The node information includes cell ID, TRP ID, TA, scene ID and / or area ID; the resource information includes beam information, bandwidth information, and / or frequency information.
[0110] Specifically, in some embodiments of the present invention, AI / ML requires UE-side computing resources. Some UEs in the network may support AI / ML-based predictive RRM measurements, while others may not. Alternatively, different UEs may have significantly different predictive RRM measurement capabilities. Therefore, to support predictive RRM measurements, the gNB needs to know whether the UE has predictive RRM measurement capabilities. This allows the gNB to provide appropriate configurations to the UE.
[0111] In some embodiments of the present invention, the prediction-based RRM measurement capability information reported by the UE to the gNB or the network side (gNB, core network element, third party, etc.) includes at least one or more of the following information:

[0118] Note 1: All of the above capabilities may further include predicting time, that is, the ability to predict the start time (start time) and end time (end time) of the time range in which an event occurs.
[0119] Note 2: All of the above capabilities may further include accuracy, that is, the probability of predicting an event to occur, 10%, 20%, 30%...

[0121] Example: Predicting RRM measurement capability triggering reporting
[0122] The gNB sends an RRM (Mobility) Prediction Capability Request message to the UE, requesting the UE to report its RRM (Mobility) prediction capabilities. After receiving the RRM (Mobility) Prediction Capability Request, the UE responds with an RRM (Mobility) Prediction Capability Report (including at least one of the following information: handover failure prediction support, radio link failure prediction support, cell-level RRM prediction support, beam-level RRM prediction support, cell-level handover prediction support, and / or beam-level handover prediction support) to the gNB.
[0123] Example: Carrying in UE capability report
[0124] The UE carries an RRM (mobility) prediction capability report in the capability report (including at least one of the following information: handover failure prediction support, radio link failure prediction support, cell-level RRM prediction support, beam-level RRM prediction support, cell-level handover prediction support, and / or beam-level handover prediction support).

[0126] The network may also send a request message to the UE with a cell ID / SSB-index to inquire whether the UE supports specific cells and beams, such as handover failure and RRM prediction.
[0127] Second embodiment: At least one network node predicts UE trajectory prediction information based on an AI / ML model
[0128] Figure 3A is a flow chart of a wireless communication method provided in an embodiment of the present application. As shown in Figure 3A, the wireless communication method is executed on a user equipment (UE) and includes at least one of the following operations: Operation 301: Receive UE trajectory prediction information sent by at least one network node, which is predicted by the at least one network node based on an artificial intelligence / machine learning AI / ML model, wherein the UE trajectory prediction information includes at least one of the following information: UE identification information, predicted UE RRM measurement results, predicted measurement result time, prediction accuracy information, node information, node access resource information, node access resource validity information, and / or node access resource prediction accuracy information.
[0129] Figure 3B is a flow chart of a wireless communication method provided in an embodiment of the present application. As shown in Figure 3B, the wireless communication method is executed on at least one network node and includes at least one of the following operations: Operation 302: Sending UE trajectory prediction information predicted by the at least one network node based on an artificial intelligence / machine learning AI / ML model to a user equipment UE, wherein the UE trajectory prediction information includes at least one of the following information: UE identification information, predicted UE RRM measurement results, predicted measurement result time, prediction accuracy information, node information, node access resource information, node access resource validity information, and / or node access resource prediction accuracy information.
[0130] Specifically, the UE is, for example, the user equipment 120 shown in Figure 1. At least one network node is, for example, the base station 110 and / or the network 130 (first network node) shown in Figure 1. The base station 110 is, for example, a gNB. Exemplarily, in some embodiments of the present invention, the UE 120 receives UE trajectory prediction information sent by at least one network node, which is predicted by at least one network node based on an artificial intelligence / machine learning AI / ML model. In this way, the movement trajectory of the user equipment 120 can be predicted through the AI / ML algorithm, thereby better allocating wireless resources and mobility management to the user equipment 120. This can also solve conventional technical problems. Conventional technical problems, for example, are that existing radio resource management (RRM) measurement results do not support measurement reporting at future times. The UE will predict possible RRM measurement results at a certain point in the future based on historical information, which will generate misleading information. In addition, in traditional switching, there will be a problem of switching delay.
[0131] In some embodiments of the present invention, the UE identification information is used to identify the UE to which the information belongs. In some embodiments of the present invention, the UE identification information is a user globally unique identifier or a radio network terminal identifier (RNTI). In some embodiments of the present invention, the predicted UE RRM measurement result is the same as the measurement result reported by the UE.
[0132] In some embodiments of the present invention, the predicted UE RRM measurement result time refers to a time range of an expected measurement result, and the predicted measurement result time is an absolute time or a relative time. In some embodiments of the present invention, the predicted measurement result time includes at least one of the following times: a predicted measurement result time range start time, a predicted measurement result time range end time, and / or a valid time window.
[0133] Specifically, in some embodiments of the present invention, the predicted measurement result time includes the start time of the time range of the expected measurement result, which can be an absolute time or a delta relative to the current time. The predicted measurement result time includes the end time of the time range of the expected measurement result. The predicted measurement result time includes a valid time window.
[0134] In some embodiments of the present invention, the prediction accuracy information includes at least one of the following: a measurement error range of the Reference Signal Received Power (RSRP) of the expected measurement result and / or a measurement error range of the time of the expected measurement result. Specifically, in some embodiments of the present invention, the predicted measurement result accuracy may be an RSRP error of 10%, 20%, or a time error of 1 second, 2 seconds, or the like.
[0135] In some embodiments of the present invention, the node information is used to indicate identification information of the switching node, and the node information includes at least one of the following information: area ID, cell ID, transmitting and receiving point TRP ID, and / or tracking area TA. In some embodiments of the present invention, the node access resource information is used to indicate resources used by the switching node for switching or access in the future, and the switching node access resource information includes at least one of the following resources: beam, spectrum, and / or bandwidth.
[0136] In some embodiments of the present invention, the node access resource validity information is used to indicate the handover node access resource corresponding to the handover node, or the effective time or effective area of the handover node. Specifically, in some embodiments of the present invention, the validity information can be a time description, including one or more of a start time, an end time, and a duration. In addition, the validity information can also be expressed as a coverage range, such as a TA; it can also be expressed as a UE trajectory range; or it can be expressed in other ways.
[0137] In some embodiments of the present invention, the node access resource validity information includes a first implementation method or a second implementation method. The first implementation method means that each access resource corresponds to an access resource validity information, which is used to characterize the effective time of each access resource. The second implementation method means that the order of access resources is used to represent the effective time order of the access resources, and the corresponding time interval.
[0138] Specifically, in some embodiments of the present invention, in order to further reduce configuration overhead and taking into account that measurement resources (CSI-RS or SSB, etc.) are in a periodic transmission state, the implementation of the node access resource validity message includes two implementations, as described below.
[0139] First implementation: Direct representation: In this solution, each access resource is associated with access resource validity information, which represents the effective time of the resource. For example, {(Beam 1, time 1), (Beam 2, time 2)} indicates that the time corresponding to Beam 1 is time 1, and the effective time corresponding to Beam 2 is time 2.
[0140] Second implementation: Sequential representation: In this solution, the order of access resources represents the order in which they become effective, along with the corresponding time intervals. For example, {Beam 1, Beam 2, Beam 3} indicates that Beam 1 is available at time T0, Beam 2 at time T0+DeltaT, and Beam 2 at time T0+2*DeltaT. DeltaT can be predefined or configured for the UE by the base station.
[0141] In some embodiments of the present invention, the node access resource prediction accuracy information is used to represent the access resources corresponding to the switching node or the prediction accuracy of the switching node. In some embodiments of the present invention, the node access resource prediction accuracy information includes a first mode, a second mode, or a third mode, wherein the first mode means that all switching node access resources share one accuracy, the second mode means that each switching node access resource corresponds to one accuracy, and the third mode means that one or more of all switching node access resources share one accuracy. In some embodiments of the present invention, the UE assists the at least one network node in configuring through UE assistance information.
[0142] Specifically, in some embodiments of the present invention, for the prediction accuracy information of the switching node access resources, its expression can be three modes. One mode is that all switching node access resources share one accuracy, that is, the accuracy corresponding to all switching node access resources. The second mode is that each switching node access resource corresponds to a separate accuracy. The third mode is that one or more of all switching node access resources share one accuracy. The three accuracy modes provided can greatly reduce the feedback overhead and provide relatively high flexibility for the implementation of AI / ML on the UE side. For example, the acquisition of the switching node access resources can be obtained by one AI / ML model or by different AI / ML models.
[0143] In some embodiments of the present invention, the above information representation is illustrated by way of example: {AI Model #1, Cell #1, Beam #1, Time window #1, 90%} indicates that when AI Model #1 is used, the accuracy of Beam #1 corresponding to Cell #1 during Time window #1 is 90%; and {AI Model #1, Cell #1, Time window #1, 90%} indicates that when AI Model #1 is used, the accuracy of Cell #1 during Time window #1 is 90%. Other examples are not described further here.
[0144] Specifically, in some embodiments of the present invention, the UE may also assist the at least one network node in configuring measurement reporting through UE assistance information / (predicted) measurement configuration. Preferably, the measurement configuration includes which SSBs of which neighboring cells are measured. In other words, the predicted neighboring cell beam switching is reported in the UE assistance information rather than in the first predicted measurement information.
[0145] As shown in Figure 3C , in some embodiments of the present invention, AI / ML-based mobility prediction is deployed on the network side. After the network-side AI / ML model completes the UE's mobility handover prediction, it sends the prediction result to the UE. The UE then initiates a mobility handover action to the target node based on the obtained result. Both the network and the gNB can predict the UE's measurement results.
[0146] As shown in Figure 3C, in some embodiments of the present invention, the at least one network node includes a base station 110 and a first network node, where base station 110 is, for example, a gNB and the first network node is, for example, network 130. The method also includes base station 110 obtaining the UE trajectory prediction information from the first network node. In some embodiments of the present invention, the UE trajectory prediction information obtained by base station 110 from the first network node includes at least one of the following information: the UE identification information, the predicted UE RRM measurement result, the predicted measurement result time, and / or the prediction accuracy information.
[0147] Specifically, as shown in Figure 3C, the base station 110 (for example, a gNB) obtains UE trajectory prediction information from the first network node (for example, the network 130).
[0148] 1) Message 1: The gNB obtains UE trajectory prediction information from the network
[0149] The gNB obtains UE trajectory prediction information from the network side, which includes one or more entities such as AMF, SMF, UPF, NEF, DWDAF, MEC, and a third party. For example, if the gNB obtains UE trajectory prediction information from the AMF, the UE trajectory prediction information can be carried in the INITIAL CONTEXT SETUP REQUEST message. If the gNB obtains UE trajectory prediction information directly from a third party, the message can be carried in the UDP or TCP protocol. Other methods are not described here. The UE trajectory prediction information obtained by the gNB includes at least one of the following information.
[0150] UE identification information: This message is used to identify the UE to which the information belongs. The identification information can be a user globally unique identifier or RNTI information, without any limitation.
[0151] Predicted UE measurement RRM result: This parameter is the same as the measurement result reported by the UE.
[0152] Predicted measurement result time: The effective time of the prediction result, which is equivalent to the start time and end time of the first embodiment.
[0153] Prediction accuracy and information accuracy.
[0154] Based on the acquired information, the gNB configures the UE's current mobility handover measurement process. This process is implemented in the same manner as the RRM measurement configuration process and is not described further here. For example, after obtaining the predicted UE trajectory, the gNB configures a measurement object for the UE and sends the predicted target cell's SSB index to the measurement object.
[0155] As shown in Figure 3C, in some embodiments of the present invention, the at least one network node includes a base station 110 and a first network node, where base station 110 is, for example, a gNB and the first network node is, for example, network 130. The method further includes, after base station 110 obtains the UE trajectory prediction information from the first network node, sending the UE trajectory prediction information to UE 120. In some embodiments of the present invention, after base station 110 obtains the UE trajectory prediction information from the first network node, the UE trajectory prediction information sent by base station 110 to UE 120 includes at least one of the following information: the node information, the node access resource information, the node access resource validity information, and / or the node access resource prediction accuracy information.
[0156] Specifically, as shown in Figure 3C, after the base station 110 (for example, a gNB) obtains the UE predicted RRM from the first network node (for example, the network 130), it sends the UE prediction result.
[0157] 2) Message 2: After the gNB obtains the UE predicted RRM from the network, it sends the UE prediction result.
[0158] In this solution, the network side (including base stations, core network elements, MEC, and third-party implementation entities) obtains the current UE's RRM measurement prediction information through algorithms or AI / ML, and configures the UE's RRM measurement process based on the obtained prediction information. The information configured to the UE by the network side includes at least one or more of the following:
[0159] Node information: This information is used to indicate the identification information of the handover node. This information can be one or more of area ID, cell ID, TRP ID, TA, etc.
[0160] Node access resource information: used to indicate the resources that the switching node will use for switching or access in the future. The resources here include at least one of beam, spectrum, and bandwidth.
[0161] Node access resource validity information: This information describes the validity period or area of the handover node access resource corresponding to the handover node. This validity information can be expressed as a time description, including one or more of the start time, end time, and duration. Furthermore, this validity information can also be expressed as a coverage area, such as a TA; as the UE's trajectory range; or in other ways.
[0162] Node access resource prediction accuracy information: used to describe the prediction accuracy of the access resource corresponding to the handover node.
[0163] In order to further reduce configuration overhead and considering that measurement resources (CSI-RS or SSB, etc.) are in a periodic transmission state, the implementation of the node access resource validity message includes two methods, as described below.
[0164] Direct representation: In this scheme, each access resource is associated with a specific access resource validity information, which represents the effective time of the resource. For example, {(Beam 1, time 1), (Beam 2, time 2)} indicates that the effective time corresponding to beam 1 is time 1, and the effective time corresponding to beam 2 is time 2.
[0165] Sequential representation: In the solution, the order of access resources indicates the order in which they become available and the corresponding time intervals.
