Description

Communication method, apparatus, storage medium and program product

[0001] The present application claims priority to the Chinese patent application No. 202411069496.8, filed on August 5, 2024, entitled "Communication method, apparatus, storage medium and program product", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a communication method, apparatus, storage medium and program product. BACKGROUND

[0003] A communication network can employ artificial intelligence (AI) technology to optimize network performance and improve user experience. For example, in a radio resource management (RRM) measurement mechanism combined with AI technology, a network device can configure a terminal device to employ AI technology to obtain a predicted measurement result. When obtaining the predicted measurement result, the terminal device can obtain both an actual measurement result and a predicted measurement result. The current terminal device can not correctly trigger measurement reporting. SUMMARY

[0004] Embodiments of the present application provide a communication method, apparatus, storage medium and program product, which can ensure that a terminal device correctly triggers measurement reporting.

[0005] In a first aspect, embodiments of the present application provide a communication method applied to a terminal device, or a chip in the terminal device, or an apparatus used in combination with the terminal device, or an apparatus for implementing the functions of the terminal device, etc. The method comprises: receiving first information from a network device, the first information being used to instruct the terminal device to measure a first measurement object and an event of measurement reporting; obtaining a predicted measurement result of the first measurement object based on the first information and a prediction function of the terminal device; and sending a measurement report to the network device when the predicted measurement result of the first measurement object meets the event of measurement reporting, the measurement report comprising the predicted measurement result of the first measurement object.

[0006] Implementing the method described in the first aspect can ensure that the terminal device correctly triggers measurement reporting by explicitly specifying the behavior of the terminal device triggering measurement reporting, i.e., triggering the reporting of the measurement report based on the predicted measurement result of the first measurement object.

[0007] In a possible implementation, the method further includes: receiving second information from the network device, the second information being used to indicate that the measurement report is reported based on the prediction function. The measurement report based on the prediction function can enable the terminal device to obtain the predicted measurement result of the first measurement object based on the prediction function, thereby triggering the reporting of the measurement report.

[0008] In this way, the network device can configure the behavior of the terminal device to trigger the reporting of the measurement, thereby further ensuring the correct triggering of the reporting of the measurement.

[0009] In a possible implementation, the measurement report includes third information, the third information being used to indicate that the measurement report is reported based on the prediction function. The measurement report reported based on the prediction function can be understood as that the predicted measurement result of the first measurement object triggering the measurement report is obtained based on the prediction function.

[0010] In this way, the terminal device can select the behavior of the correct triggering of the reporting of the measurement by itself and inform the network device through the third message.

[0011] In a possible implementation, the prediction function is a time-domain prediction function, a space-domain prediction function, or a frequency-domain prediction function. The time-domain prediction function refers to predicting the future measurement result of a cell according to the actual measurement result of the cell. The space-domain prediction function refers to predicting the measurement result of a part of beams (or synchronization signal blocks, SSBs) in a cell according to the actual measurement result of the part of beams (or SSBs) in the cell. The frequency-domain prediction function refers to predicting the measurement result of a different frequency neighbor cell of a cell according to the actual measurement result of the cell.

[0012] In a possible implementation, the prediction function is a time-domain prediction function, and the method further includes: receiving fourth information from the network device, the fourth information being used to indicate the reporting of the actual measurement result of the first measurement object; wherein the measurement report further includes the actual measurement result of the first measurement object, and the actual measurement result of the first measurement object is obtained when the predicted measurement result of the first measurement object meets the event of the reporting of the measurement.

[0013] In this way, the actual measurement result of the first measurement object is additionally carried in the measurement report, which can meet the demand of the network device for obtaining the actual measurement result.

[0014] In a possible implementation, the prediction function is a space-domain prediction function, and the method further includes: receiving fifth information from the network device, the fifth information being used to indicate the reporting of the first index, the first index being used to indicate the synchronization signal block actually measured for obtaining the predicted measurement result of the first measurement object, and the measurement report further includes the first index.

[0015] In this mode, the first index is additionally carried in the measurement report, which can inform the network device of the SSB actually measured by the terminal device this time, so that the network device can refer to the first index to issue a new measurement configuration to the terminal device.

[0016] In a possible implementation, the prediction function is a frequency domain prediction function, the first measurement object includes an inter-frequency neighbor cell of the serving cell, the event includes a first event and / or a second event, and the measurement report further includes an actual measurement result of the serving cell; wherein the first event is that the predicted measurement result of the inter-frequency neighbor cell is higher than the actual measurement result of the serving cell by a first threshold; and the second event is that the actual measurement result of the serving cell is lower than a second threshold and the actual measurement result of the inter-frequency neighbor cell is higher than a third threshold.

[0017] In this mode, whether the first event and / or the second event is satisfied can be determined based on the predicted measurement result of the inter-frequency neighbor cell and the actual measurement result of the serving cell, so that the measurement reporting can be triggered correctly.

[0018] In a possible implementation, the method further includes: receiving sixth information from the network device, the sixth information being used to indicate that the performance of the prediction function is monitored; and sending a monitoring report of the performance of the prediction function to the network device.

[0019] In this mode, the network device can also configure the terminal device to monitor the performance of the prediction function, and accordingly, the terminal device can report a corresponding monitoring report.

[0020] In a possible implementation, the monitoring report includes an actual measurement result of the first measurement object or a prediction error of the first measurement object, wherein the prediction error is determined based on the actual measurement result of the first measurement object and the predicted measurement result of the first measurement object.

[0021] In this mode, if the monitoring report includes the actual measurement result of the first measurement object, the network device can determine the performance of the prediction function based on the monitoring report and the measurement report (the predicted measurement result of the first measurement object in the measurement report); or if the monitoring report includes the prediction error of the first measurement object, the network device can determine the performance of the prediction function based on the prediction error.

[0022] In a possible implementation, the above sending of the measurement report to the network device includes: when the monitoring report indicates that the performance of the prediction function is better than a fourth threshold, sending the measurement report to the network device.

[0023] In this mode, the measurement report can be reported when the performance of the prediction function is better than the fourth threshold, so that the reporting of the measurement report is more effective and more referential. Optionally, when the monitoring report indicates that the performance of the prediction function is worse than the fourth threshold, the measurement report is not sent to the network device, so that the signaling overhead is saved.

[0024] In a possible implementation, the sixth information includes a monitoring period, a monitoring duration, and a monitoring offset.

[0025] In a possible implementation, the measurement report based on the prediction function is stopped reporting in the monitoring time determined by the sixth information.

[0026] In this way, the measurement report based on the prediction function can be stopped reporting in the monitoring time, which not only saves the power consumption of the terminal device in prediction, but also saves the signaling overhead. The monitoring report is reported in the monitoring time. Optionally, the monitoring report can be stopped reporting at the end of the monitoring time, and the measurement report based on the prediction function can be resumed.

[0027] In a possible implementation, the sixth information further includes a reporting manner of the monitoring report; and the reporting manner of the monitoring report is reporting when an event of measurement reporting is met, or the reporting manner of the monitoring report is a periodic reporting manner.

[0028] In this way, when the reporting manner is reporting when the event of measurement reporting is met, the event of measurement reporting can be reused, and there is no need to additionally configure the event of reporting for the monitoring report, which can save the signaling overhead.

[0029] In a second aspect, an embodiment of the present application provides another communication method, which is applied to a network device, or a chip in the network device, or an apparatus used in combination with the network device, or an apparatus for implementing the function of the network device, etc. The method includes: sending first information to a terminal device, the first information being used to instruct the terminal device to measure a first measurement object and an event of measurement reporting; receiving a measurement report from the terminal device, the measurement report including a predicted measurement result of the first measurement object, the predicted result of the first measurement object being obtained based on the first information and a prediction function of the terminal device; wherein the measurement report is reported based on second information sent to the terminal device, the second information being used to instruct the measurement report to be reported based on the prediction function; and / or the measurement report includes third information, the third information being used to instruct the measurement report to be reported based on the prediction function.

[0030] The method described in the second aspect is implemented, the network device can configure the terminal device to trigger the behavior of measurement reporting through the second information, or the terminal device selects the correct behavior of triggering the measurement reporting by itself and informs the network device through the third message, the behavior of triggering the measurement reporting of the terminal device is triggered based on the predicted measurement result of the first measurement object to report the measurement report, so that the behavior of the terminal device can be ensured by explicitly indicating the behavior of the terminal device to ensure that the terminal device correctly triggers the measurement reporting.

[0031] In a possible implementation, the prediction function is a time domain prediction function, a space domain prediction function, or a frequency domain prediction function.

[0032] In a possible implementation, the prediction function is a time domain prediction function, and the method further includes: sending, to the terminal device, fourth information used to indicate reporting of an actual measurement result of the first measurement object; and wherein the measurement report further includes the actual measurement result of the first measurement object, and the actual measurement result of the first measurement object is obtained when the predicted measurement result of the first measurement object meets the measurement reporting event.

[0034] In a possible implementation, the prediction function is a frequency domain prediction function, the first measurement object includes an inter-frequency neighbor cell of a serving cell, the event includes a first event and / or a second event, and the measurement report further includes an actual measurement result of the serving cell; wherein the first event is that the predicted measurement result of the inter-frequency neighbor cell is higher than the actual measurement result of the serving cell by a first threshold value; and the second event is that the actual measurement result of the serving cell is lower than a second threshold value and the actual measurement result of the inter-frequency neighbor cell is higher than a third threshold value.

[0035] In a possible implementation, the method further includes: sending, to the terminal device, sixth information used to indicate monitoring of performance of the prediction function; and receiving a monitoring report of the performance of the prediction function from the terminal device.

[0060] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0061] In order to facilitate understanding of the scheme provided by the embodiments of the present application, the related concepts involved in the embodiments of the present application are introduced as follows:

[0062] I. The R17 version of the 3rd generation partnership project (3GPP) proposes to apply artificial intelligence (AI) technology to the field of communication networks to optimize network performance and improve user experience. For example, for the application of AI technology on the radio access network (RAN) side, the following scenarios are designed: energy saving, load balancing, mobility optimization, channel state information reference signal (CSI-RS) feedback enhancement, beam scanning enhancement, positioning enhancement, etc.

[0063] To meet the needs of various application scenarios, a terminal device is usually configured with multiple functionalities and AI models corresponding to the functionalities. Among them, the functionalities and / or AI models can be activated or deactivated, the functionalities and / or AI models are in an activated state after being activated, and the functionalities and / or AI models are in a deactivated state after being deactivated or not activated. Taking an application scenario as an example, when the application scenario has a use demand of AI technology, the functionalities and / or AI models can be activated, and then the terminal device uses the functionalities and / or AI models to perform corresponding operations; when the application scenario temporarily has no use demand of AI technology, the functionalities and / or AI models can be deactivated, and the above-mentioned activation and deactivation process can also be referred to as life cycle management (LCM) of AI models.

[0064] FIG. 1 shows a flowchart of LCM, as shown in FIG. 1, including a terminal device (user equipment, UE) and a network (network, NW), performing the following steps 101 to 105:

[0065] 101. The UE sends capability information and / or assistance information to the NW.

[0066] Among them, the capability information is used to indicate the AI application scenarios supported by the UE, for example, the capability information includes but is not limited to: the functionalities supported by the UE and / or the AI models supported by the UE, etc. The assistance information is used to indicate the specific information of the functionalities and / or AI models supported by the UE, for example, the applicable conditions of the functionalities and / or AI models, or the application scenarios to which the functionalities and / or AI models are applicable, or whether the functionalities and / or AI models are applicable to the current application scenario, etc.

[0067] 102. The NW makes a management decision based on the capability information and / or the assistance information.

[0068] Among them, the NW can make a management decision based on the capability information and / or the assistance information, including but not limited to: determining to activate / deactivate / switch / rollback the functionalities and / or AI models, etc. For example, the capability information and / or the assistance information indicate that the functionalities and / or AI models supported by the UE support the current application scenario, then the NW determines to send an activation instruction of the functionalities and / or AI models to the UE.

[0069] 103. The NW sends a management instruction to the UE.

[0070] The management instruction refers to an instruction related to the management decision, including but not limited to: activation instruction / deactivation instruction / switching instruction / backoff instruction, etc.

[0071] 104. The UE sends performance information to the NW.

[0072] For example, after receiving the activation instruction sent by the NW, the UE activates the corresponding functionality and / or AI model, and then performs operations based on the functionality and / or AI model. In this process, the UE can monitor the performance when performing operations based on the functionality and / or AI model, thereby obtaining performance information. For example, taking the radio resource management (RRM) measurement in the mobility management scenario as an example, the measurement result can be predicted based on the functionality and / or AI model, and the performance information includes but is not limited to: one or more of the predicted error, the actual measurement result, and the predicted measurement result.

[0073] 105. The NW makes a management decision based on the performance information.

[0074] The NW can make a management decision based on the performance information, including but not limited to: determining whether to deactivate / switch / backoff the functionality and / or AI model according to the performance indicated by the performance information. For example, when the performance indicated by the performance information is poor, it is determined to stop the UE from continuing to use the functionality and / or AI model, i.e., to deactivate the functionality and / or AI model.

[0075] 106. The NW sends a management instruction to the UE.

[0076] For example, the NW can determine to deactivate the functionality and / or AI model based on the performance information, and then send a deactivation instruction to the UE.

[0077] II. In the RRM measurement mechanism, the base station sends measurement configuration information to the UE, and the measurement configuration information includes a measurement identifier (measid), a measurement object (measObjectld), and a report configuration (reportConfigld). Wherein:

[0078] The measurement identifier is used to associate the measurement object and the report configuration.

[0079] Measurement object is used to indicate the object that UE needs to measure, including one or more of serving cell, intra-frequency neighbor cell, inter-frequency neighbor cell or inter-system cell, and the measurement object is represented by reference signal (such as synchronization signal / PBCH block (SSB) or CSI-RS), subcarrier spacing, time-frequency information, etc.

[0080] The reporting configuration includes the reporting type and the configuration corresponding to the reporting type. For example, the type of the report can be event triggered reporting, and the configuration corresponding to the event triggered reporting includes corresponding threshold value, hysteresis, and time to trigger (TTT), etc. For example, the events include A series events (A1 event to A5 event), Thresh represents the threshold value, Hys represents the hysteresis parameter, and the following describes the several events:

[0081] A1 event: the signal quality (Ms) of the serving cell is higher than the threshold value, the entering condition of the A1 event is Ms-Hys>Thresh, and the exiting condition is Ms+Hys<Thresh.

[0082] A2 event: the signal quality (Ms) of the serving cell is lower than the threshold value, the entering condition of the A2 event is Ms+Hys<Thresh, and the exiting condition is Ms-Hys>Thresh.

[0083] A3 event: the signal quality (Mn) of the neighbor cell is higher than the signal quality (Mp) of the serving cell by a bias value, the entering condition of the A3 event is Mn+Ofn+Ocn-Hys>Mp+Ofp+Ocp+Off, and the exiting condition is Mn+Ofn+Ocn+Hys<Mp+Ofp+Ocp+Off. Wherein, Ofn is the frequency (which can also be replaced by frequency point or frequency band) bias value of the neighbor cell, Ocn is the cell bias value (CIO) of the neighbor cell, Ofp is the frequency (which can also be replaced by frequency point or frequency band) bias value of the serving cell, Ocp is the cell bias value of the serving cell, and Off is the A3 event bias value. Wherein, for intra-frequency measurement, Ofn and Ofp are 0, i.e. not considered.

[0084] A4 event: the signal quality (Mn) of the neighbor cell is higher than the threshold value, the entering condition of the A4 event is Mn+Ofn+Ocn-Hys>Thresh, and the exiting condition is Mn+Ofn+Ocn+Hys<Thresh.

[0085] A5 event: the signal quality of the serving cell (Mp) is lower than a threshold value (Thresh#1), and the signal quality of the neighbor cell (Mn) is better than another threshold value (Thresh#2). The entering condition of the A5 event is: Mp+Hys<Thresh#1 and Mn+Ofn+Ocn-Hys>Thresh#2, and the exiting condition is: Mp-Hys>ThreshA#1 and Mn+Ofn+Ocn+Hys<Thresh#2.

[0086] In the embodiments of the present application, when the duration of the entering condition of any event reaches the trigger time (TTT), it is referred to as satisfying any event, and when any event is satisfied, the UE triggers measurement reporting.

[0087] III. In the RRM measurement mechanism combined with the AI technology, the functionality and the AI model corresponding to the functionality can be started to predict the RRM measurement. The present application refers to the functionality and the AI model corresponding to the functionality as a prediction function, and the types of the prediction function include a time domain prediction function, a space domain prediction function, and a frequency domain prediction function. The time domain prediction function and the space domain prediction function are applicable to intra-frequency measurement, and the frequency domain prediction function is applicable to inter-frequency measurement:

[0088] (1) Time domain prediction function refers to predicting future measurement results of a cell according to current actual measurement results of the cell. Taking the RSRP of the cell as an example, as shown in FIG. 2, the prediction window length (Prediction Window) represents the time range of prediction, that is, how long the measurement results in the future can be predicted. For example, assuming that the time domain prediction function is used at T1, the actual measurement results of the cell at T1 are first obtained, which include the actual measured value of RSRP at T1, and then the time domain prediction is performed with the actual measured value of RSRP at T1 as a reference to obtain the predicted measurement results of the cell at T1. It should be understood that the predicted measurement results of the cell at T1 refer to the predicted measurement results obtained by performing time domain prediction at T1, and do not refer to predicting the measurement results of the cell at T1. The predicted measurement results of the cell at T1 include the predicted value of RSRP at T3, and the time interval between T3 and T1 is equal to the Prediction Window. Similarly, assuming that the time domain prediction function is used at T2, the actual measurement results of the cell at T2 are first obtained, which include the actual measured value of RSRP at T2, and then the time domain prediction is performed with the actual measured value of RSRP at T2 as a reference to obtain the predicted measurement results of the cell at T2. It should be understood that the predicted measurement results of the cell at T2 refer to the measurement results obtained by performing time domain prediction at T2, and do not refer to predicting the measurement results of the cell at T2. The predicted measurement results of the cell at T2 include the predicted value of RSRP at T4, and the time interval between T4 and T2 is the Prediction Window.

[0089] Optionally, the time domain prediction function can be continuously used in the time interval between T1 and T2, so that the predicted values of RSRP in the time interval between T3 and T4 can be continuously obtained.

[0090] (2) Spatial domain prediction function refers to predicting the measurement results of a part of beams (or SSBs) in a cell according to the actual measurement results of the rest of beams (or SSBs) in the cell. As shown in FIG. 3, a cell is completely covered by beams a1 to a4, and thus the measurement results of the cell need to be obtained based on the measurement results of beams a1 to a4; wherein, when the spatial domain prediction function is used, the actual measurement (i.e. actual measurement) of beams a1 and a2 is first performed to obtain the actual measured value of beam a1 and the actual measured value of beam a2, and then the measurement results of beams a3 and a4 are predicted based on the actual measured value of beam a1 and the actual measured value of beam a2 to obtain the predicted value of beam a3 and the predicted value of beam a4.

[0091] Optionally, the spatial domain prediction function can be continuously used, that is, the predicted values of beams a3 and a4 can be continuously obtained based on the actual measured value of beam a1 and the actual measured value of beam a2.

[0092] It should be noted that the above-mentioned beam refers to the transmission or reception effect with directivity formed by the transmitter or receiver through the antenna array. The beam is generally corresponding to a resource, for example, when performing beam measurement, different resources are used to measure different beams, that is, the quality of the corresponding beam is characterized by the measured resource quality, and the resource includes but is not limited to SSB and the like. The beam can also be referred to as a digital beam, an analog beam, a spatial domain filter, a spatial filter, a spatial parameter, and the like. The beam used for transmitting a signal can be referred to as a transmission beam, a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, and the like. The beam used for receiving a signal can be referred to as a reception beam, a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, and the like. The following content is described in terms of beams, but the beam can be alternatively understood as other equivalent concepts, and is not limited to the above-mentioned concepts.

[0093] (3) The frequency domain prediction function refers to predicting the measurement result of the inter-frequency neighbor cell of a cell according to the actual measurement result of the cell. The frequency domain prediction function is for inter-frequency measurement. As shown in FIG. 4, in the inter-frequency measurement, not only the measurement result of cell 1 needs to be obtained, but also the measurement result of the inter-frequency neighbor cell of cell 1 needs to be obtained; wherein, when using the frequency domain prediction function, first, the actual measurement (i.e. actual measurement) of cell 1 is performed to obtain the actual measurement value of cell 1, and then the actual measurement value of cell 1 is used as a reference to predict the measurement result of the inter-frequency neighbor cell of cell 1 to obtain the predicted value of the inter-frequency neighbor cell of cell 1. It should be understood that when predicting the measurement result of the inter-frequency neighbor cell of cell 1, the UE does not need to be adjusted to the frequency band where the inter-frequency neighbor cell of cell 1 is located, that is, the UE can obtain the actual measurement value of cell 1 and the predicted value of the inter-frequency neighbor cell of cell 1 in the frequency band of cell 1, which can save the power consumption of the UE.

[0094] In the RRM measurement mechanism without AI technology, when the UE reports the measurement according to the event trigger, it is based on the actual measurement result. For example, the measurement configuration information includes A3 event, the UE obtains the signal quality of the serving cell and the signal quality of the neighbor cell based on the actual measurement, and then judges whether the A3 event is met based on the signal quality of the serving cell and the signal quality of the neighbor cell. After meeting the event, the measurement report is reported.

[0095] However, in the RRM measurement mechanism combined with AI technology, as can be known from the above introduction of the time domain / space domain / frequency domain prediction function, the UE needs to take the actual measurement result as a reference for prediction, that is, the UE first obtains the actual measurement result through actual measurement, and then obtains the predicted measurement result based on the actual measurement result, which leads to that the UE can obtain both the actual measurement result and the predicted measurement result. For example, still taking the A3 event as an example, when the UE uses the time domain prediction function, it can obtain the actual measurement result of the serving cell, the predicted measurement result of the serving cell, the actual measurement result of the neighbor cell, and the predicted measurement result of the neighbor cell. For example, the neighbor cell is a same-frequency neighbor cell, the measurement time is T1, and the measurement result is RSRP. Then, the actual measurement result of the serving cell is the measured value of the RSRP of the serving cell at T1, the predicted measurement result of the serving cell is the predicted value of the RSRP of the serving cell at T3, the actual measurement result of the neighbor cell is the measured value of the RSRP of the neighbor cell at T1, and the predicted measurement result of the neighbor cell is the predicted value of the RSRP of the neighbor cell at T3.

[0096] When the UE can obtain both the actual measurement result and the predicted measurement result, it is not clear how to judge whether the event of measurement reporting is met, that is, the UE is not clear which predicted result is used to judge whether the entering condition and the exiting condition of the event are met, which may lead to that the UE triggers the measurement reporting incorrectly, that is, the reported measurement result cannot provide a reference for the base station decision, thereby affecting the subsequent mobility handover process. For example, one possible way is that the UE judges whether the A3 event is met based on the measured value of the RSRP of the serving cell at T1 and the predicted value of the RSRP of the neighbor cell at T3. These two measurement results are measurement results at different times, which leads to that the UE judges incorrectly, and further affects the subsequent base station decision and terminal handover.

[0097] In order to make the UE correctly trigger the measurement reporting in the RRM measurement scene combined with AI technology, the communication method provided in the embodiments of the present application is proposed, which can be applied to the communication system shown in FIG. 5.

[0098] As shown in FIG. 5, the communication system includes a network device 510 and a terminal device 520. FIG. 5 takes one network device 510 and one terminal device 520 as an example, and the communication system can also include a larger number of network devices 510 and terminal devices 520, which are not limited in the embodiments of the present application.

[0099] The network device 510 can also be referred to as an access network device, which refers to a RAN node (or device) for accessing the terminal device 520 to the wireless network, and can also be referred to as a base station. For example, the RAN node can be a continued evolution of NodeB (gNB), a transmission reception point (TRP), an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB, or home Node B (HNB)), a base band unit (BBU), or a wireless fidelity (Wifi) access point (AP), etc. In addition, in a network structure, the access network device can include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including the CU node and the DU node. The RAN device including the CU node and the DU node splits the protocol layers of the gNB in the NR system, and the functions of part of the protocol layers are controlled by the CU, and the functions of the remaining part or all of the protocol layers are distributed in the DU and controlled by the CU. Further, the centralized unit CU can also be divided into a control plane (CU-CP) and a user plane (CU-UP). The CU-CP is responsible for the control plane function, mainly including the radio resource control (RRC) and the PDCP corresponding to the control plane, i.e., PDCP-C. The PDCP-C is mainly responsible for the encryption and decryption of the control plane data, integrity protection, data transmission, etc. The CU-UP is responsible for the user plane function, mainly including the SDAP and the PDCP corresponding to the user plane, i.e., PDCP-U. The SDAP is mainly responsible for processing the data of the core network and mapping the flow to the bearer. The PDCP-U is mainly responsible for the encryption and decryption of the data plane, integrity protection, header compression, sequence number maintenance, data transmission, etc. The CU-CP and the CU-UP are connected through an E1 interface. The CU-CP represents the gNB connected to the core network through an NG interface. The control plane of the F1 interface, i.e., F1-C, is connected to the DU. The CU-UP is connected to the DU through the user plane of the F1 interface, i.e., F1-U. Of course, there is also a possible implementation that the PDCP-C is also in the CU-UP.

[0100] In an embodiment of the present application, the RAN node can also be an open RAN (O-RAN), and the structure of the O-RAN is shown in FIG. 6. The O-RAN includes a RIC (ran intelligent controller, RIC), a CU, and a DU. The RIC can also be referred to as a service unit (SU). The RIC is used to obtain relevant information of AI technology from the UE, the CU, and / or the DU. For example, the RIC can obtain the capability information, the assistance information, and / or the performance information shown in FIG. 1, or the RIC can also obtain data obtained by the UE using AI technology, such as predicted measurement results obtained based on a prediction function in RRM measurement. The RIC is also used to manage the performance of AI technology according to the obtained relevant information. For example, the RIC can perform the management decision shown in FIG. 1 and perform related tasks such as sending a management instruction. Optionally, the RIC sending the management instruction can mean that the RIC controls the CU and / or the DU connected thereto to send the management instruction to the UE.

[0101] The terminal device 520 can also be referred to as a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc. It refers to a device that provides voice and / or data connectivity to a user. For example, a handheld device having wireless connection capability, a vehicle-mounted device, etc. For example, the terminal device 510 can be a mobile phone, a tablet computer, a notebook computer, a palm computer, 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.

[0102] The communication system can be an internet of things (IoT) system, a narrow band internet of things (NB-IoT) system, a long term evolution (LTE) system, a 5th-generation (5G) communication system, a new radio (NR) system, and a new communication system to be developed in the future. The IoT network can include, for example, but is not limited to, a vehicle-to-everything (V2X) system. The communication mode in the V2X system can be collectively referred to as V2X (X can represent any thing). For example, the V2X can include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, or vehicle-to-network (V2N) communication, and the like. The method provided in the embodiments of the present application can also be applied to non-terrestrial network (NTN) communication (also referred to as non-terrestrial network communication), and the like.

[0103] The communication method provided in the embodiments of the present application will be described in detail as follows:

[0104] FIG. 7 shows a flow diagram of a communication method provided in the embodiments of the present application. The execution subject of the method can be a terminal device and a network device, or the execution subject can be a chip in the terminal device and a chip in the network device, or the execution subject can be other types of products, and those skilled in the art can further expand according to the content disclosed in the specification. The execution subject of the method shown in FIG. 7 and the following method is taken as an example of a terminal device and a network device. As shown in FIG. 7, the method includes steps 701 to 703. Among them:

[0105] 701. The network device sends first information to the terminal device, the first information being used to instruct the terminal device to measure a first measurement object and an event of measurement reporting. Correspondingly, the terminal device receives the first information.

[0106] In a possible implementation, the first information is measurement configuration information, and the first information includes the first measurement object and the event of measurement reporting.

[0107] For example, the first measurement object includes, but is not limited to, a serving cell, an intra-frequency neighbor cell, or an inter-frequency neighbor cell, and the like. The measurement reporting event includes one or more event reporting configurations, and the event reporting configuration includes, but is not limited to, one or more of a threshold value, a bias value, a hysteresis parameter, or a TTT, and the like.

[0108] Optionally, the first information can further include a measurement identity, the measurement identity being used for managing the first measurement object and the measurement reporting event; and / or, the first information can further include a measurement reporting type, for example, in the embodiments of the present application, the measurement reporting type is event triggering.

[0109] In a possible implementation, the first information can be carried in RRC signaling.

[0110] In a possible implementation, the network device can further send, to the terminal device, activation information, the activation information being used for activating the prediction function. Correspondingly, the terminal device receives the activation information. For example, the activation information carries a functionality ID of the prediction function, and the terminal device receives the activation information, and activates the corresponding prediction function according to the functionality ID. Optionally, the prediction function can be a time-domain prediction function, a frequency-domain prediction function, or a space-domain prediction function, the time-domain prediction function and the space-domain prediction function being applicable to intra-frequency measurement, and the frequency-domain prediction function being applicable to inter-frequency measurement, which can be referred to the above description. For example, the functionality ID of the time-domain prediction function is “01”, and the time-domain prediction function of the terminal device can be activated by carrying the functionality ID “01” in the activation information.

[0111] In a possible implementation, the activation information can be carried in RRC signaling.

[0112] In a possible implementation, the activation information can be carried in media access control control element (MAC CE) signaling.

[0113] In a possible implementation, the RRC signaling carrying the first information and the RRC signaling carrying the activation information can be the same RRC signaling, or different RRC signaling.

[0114] In a possible implementation, the first information and the activation information can be sent to the terminal device at the same time, or the first information and the activation information can be sent to the terminal device in sequence, and the sequence of the first information and the activation information is not limited.

[0115] 702、The terminal device obtains a predicted measurement result of the first measurement object based on the first information and a prediction function of the terminal device.

[0116] In the embodiments of the present application, the prediction function of the terminal device refers to an activated prediction function of the terminal device, for example, a prediction function activated by the activation information. The terminal device can predict the measurement result based on the first measurement object included in the first information and the prediction function.

[0117] Optionally, the measurement result can be one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), or signal to interference plus noise ratio (SINR). The following description takes RSRP as an example of the measurement result.

[0118] In a possible implementation, if the prediction function is a time domain prediction function, the first measurement object can be a serving cell or a same-frequency neighbor cell of the serving cell. The time domain prediction function is performed in units of a cell, that is, the terminal device can first obtain an actual measurement result of the cell based on the first information and the time domain prediction function, and then obtain a predicted measurement result of the cell by taking the actual measurement result of the cell as a reference. For example, when the first measurement object is a serving cell (such as Cell-1), the terminal device first obtains an actual measurement value of RSRP of Cell-1, and then obtains a predicted value of RSRP of Cell-1 by taking the actual measurement value of RSRP of Cell-1 as a reference. When the first measurement object is a same-frequency neighbor cell (Cell-2) of the serving cell, the terminal device first obtains an actual measurement value of RSRP of Cell-2, and then obtains a predicted value of RSRP of Cell-2 by taking the actual measurement value of RSRP of Cell-2 as a reference.

[0119] In a possible implementation, if the prediction function is a spatial domain prediction function, the first measurement object can be a serving cell or a same-frequency neighbor cell of the serving cell, and the spatial domain prediction function is performed in a granularity of one cell, that is, the terminal device can first obtain actual measurement results of a part of beams (or SSBs) in the one cell based on the first information and the spatial domain prediction function, and then obtain predicted measurement results of another part of beams (or SSBs) in the one measurement object by taking the actual measurement results of the part of beams (or SSBs) in the one cell as reference. For example, it is assumed that the first measurement object is configured with four beams, which are beam a1 to beam a4, when the first measurement object is a serving cell (for example, Cell-1), actual values of RSRP of beam a1 to beam a2 of Cell-1 are first obtained, and then predicted values of RSRP of beam a3 to beam a4 of Cell-1 are obtained by taking the actual values of RSRP of beam a1 to beam a2 of Cell-1 as reference; when the first measurement object is a same-frequency neighbor cell (Cell-2) of the serving cell, predicted values of RSRP of beam a3 to beam a4 of Cell-2 are obtained based on actual values of RSRP of beam a1 to beam a2 of Cell-2. It should be understood that beam aX (X=1, 2, 3, 4) of Cell-1 and beam aX of Cell-2 can be the same or different, and the above example only uses the same representation.

[0120] In a possible implementation, if the prediction function is a frequency domain prediction function, the first measurement object can be a different-frequency neighbor cell of the serving cell, and the frequency domain prediction function further needs to obtain actual measurement results of the serving cell to obtain measurement results of the different-frequency neighbor cell based on the actual measurement results of the serving cell. For example, when the first measurement object includes a different-frequency neighbor cell (Cell-3) of a serving cell (for example, Cell-1), actual values of RSRP of Cell-1 are first obtained, and then predicted values of RSRP of Cell-3 are obtained by taking the actual values of RSRP of Cell-1 as reference.

[0121] 703、In a possible implementation, if the prediction function is a frequency domain prediction function, the first measurement object can be a different-frequency neighbor cell of the serving cell, and the frequency domain prediction function further needs to obtain actual measurement results of the serving cell to obtain measurement results of the different-frequency neighbor cell based on the actual measurement results of the serving cell. For example, when the first measurement object includes a different-frequency neighbor cell (Cell-3) of a serving cell (for example, Cell-1), actual values of RSRP of Cell-1 are first obtained, and then predicted values of RSRP of Cell-3 are obtained by taking the actual values of RSRP of Cell-1 as reference.

[0122] In the embodiments of the present application, the terminal device obtains the predicted measurement results of the first measurement object, and can determine whether an event of measurement reporting is met based on the predicted measurement results of the first measurement object. The behavior of the terminal device determining whether the event of measurement reporting is met based on the predicted measurement results of the first measurement object can be collectively referred to as triggering measurement reporting based on the prediction function, or can also be collectively referred to as reporting the measurement report based on the prediction function, and the like. Then, the terminal device can send the measurement report to the network device when the event of measurement reporting is met based on the predicted measurement results of the first measurement object.

[0123] The following first introduces the content in the measurement report:

[0124] The measurement report includes a predicted measurement result of the first measurement object.

[0125] For example, if the prediction function is a time domain prediction function or a frequency domain prediction function, the predicted measurement result of the first measurement object includes a predicted measurement result of the first measurement object. If the prediction function is a spatial domain prediction function, the predicted measurement result of the first measurement object includes a predicted measurement result of a first beam of the first measurement object, and the first beam is a predicted beam, such as beam a3 and beam a4 in FIG. 3. For details, refer to the example in step 702.

[0126] It should be understood that the predicted measurement result of the first measurement object in the measurement report, or the reported predicted measurement result of the first measurement object, refers to the latest obtained predicted measurement result of the first measurement object when the predicted measurement result of the first measurement object meets the measurement reporting event. For example, as shown in FIG. 8, it is assumed that at T1, the predicted measurement result of the first measurement object meets the entering condition of the event, and there is no leaving condition (or exit condition) of the event within the TTT time interval after the entering condition of the event is met, so that the measurement report can be reported at T2, the time interval between T1 and T2 is equal to TTT, and the reported measurement report includes the predicted measurement result of the first measurement object obtained at T2. Since the time domain prediction function uses the measurement result of the future time for prediction, the predicted measurement result of the first measurement object obtained at T2 is the predicted value of the RSRP of the cell at T4. For the spatial domain prediction function / frequency domain prediction function, the measurement result of the current time is predicted, so that the predicted measurement result of the first measurement object obtained at T2 is the predicted value of the RSRP of beam a3 and beam a4 of the cell at T2, and the predicted value of the RSRP of the inter-frequency neighbor cell of cell 1 at T2.

[0127] Optionally, the network device can further send fourth information to the terminal device under the time domain prediction function, and the fourth information is used to indicate the reported actual measurement result of the first measurement object. In this way, the measurement report not only includes the predicted measurement result of the first measurement object, but also includes the actual measurement result of the first measurement object.

[0128] It can be understood that the reported actual measurement result of the first measurement object refers to the latest obtained actual measurement result of the first measurement object when the predicted measurement result of the first measurement object meets the measurement reporting event.

[0129] For example, when the first measurement object comprises a serving cell (e.g., Cell-1), the measurement report comprises a predicted value of RSRP of Cell-1 and a measured value of RSRP of Cell-1. It should be understood that if reporting at T2 as shown in FIG. 8, the predicted value of RSRP of Cell-1 can be a predicted value at T4, and the measured value of RSRP of Cell-1 can be a measured value at T2.

[0130] For example, when the first measurement object comprises an intra-frequency neighbor cell of the serving cell (e.g., Cell-2), the measurement report comprises a predicted value of RSRP of Cell-2 and a measured value of RSRP of Cell-2.

[0131] Based on the above, the actual measurement result can be reported to meet the requirement of the network device to obtain the actual measurement result in the time domain.

[0132] Optionally, the network device under the spatial domain prediction function can further send fifth information to the terminal device, the fifth information being used to indicate reporting of a first index, the first index being a synchronization signal block actually measured for obtaining the predicted measurement result of the first measurement object. In this way, the measurement report reported not only comprises the predicted measurement result of the first measurement object, but also can comprise the first index.

[0133] It can be understood that the reported first index refers to an index of the latest actually measured synchronization signal block when the predicted measurement result of the first measurement object meets the event of measurement reporting.

[0134] For example, when the first measurement object comprises a serving cell (e.g., Cell-1), and beams a1 to a2 in Cell-1 are actually measured beams (hereinafter referred to as measured beams), and beams a3 to a4 are predicted beams (hereinafter referred to as predicted beams), the measurement report comprises a predicted value of RSRP of beam a3 of Cell-1, a predicted value of RSRP of beam a4 of Cell-1, an index of a SSB corresponding to beam a1 of Cell-1, and an index of a SSB corresponding to beam a2 of Cell-1. It should be understood that if reporting at T2 as shown in FIG. 8, the predicted values of RSRP of beams a3 and a4 can be predicted values at T2, and beams a1 and a2 are beams corresponding to SSBs actually measured at T2.

[0135] For example, when the first measurement object includes a same-frequency neighbor cell (such as Cell-2) of the serving cell, and beams a1 to a2 in Cell-2 are actually measured beams, and beams a3 to a4 are predicted beams, then the SSBs corresponding to beams a1 to a2 are actually measured SSBs, and the SSBs corresponding to beams a3 to a4 are predicted SSBs. It should be understood that beams aX (X=1, 2, 3, 4) of Cell-1 and beams aX of Cell-2 can be the same or different, and the above example is only an example of using the same representation. Then, the measurement report includes a predicted value of RSRP of beam a3 of Cell-2, a predicted value of RSRP of beam a4 of Cell-2, an index of the SSB corresponding to beam a1 of Cell-2, and an index of the SSB corresponding to beam a2 of Cell-2.

[0136] Based on the above, the index of the actually measured SSB can be reported to meet the requirement of the network device to obtain the actually measured SSB. It should be understood that the network device can configure the terminal device as to which beams of a cell are used for actual measurement and which beams are used for prediction, and the terminal device performs actual measurement and prediction according to the configuration, or the network device does not indicate which beams are used for actual measurement, and the terminal device autonomously selects.

[0137] Optionally, the network device under the spatial domain measurement function can also configure the terminal device to report the actual measurement result of the first measurement object. For example, the RSRP of the actually measured SSB of the first measurement object. This mode can be implemented by referring to the implementation mode of reporting the actual measurement result under the time domain measurement function, and details are not repeated here.

[0138] It should be understood that the embodiments of the present application are described with respect to a first measurement object as one cell. In a specific implementation, when the network device sends the measurement configuration information to the terminal device, the measurement object in the measurement configuration information can include multiple cells. If there is more than one cell in the multiple cells that can obtain a predicted measurement result according to the prediction function, then these cells can all report the predicted measurement result and / or the actual measurement result and / or the index of the actually measured SSB according to the above mode. For example, the measurement object includes the serving cell and the same-frequency neighbor cell of the serving cell, and the prediction function is a time domain prediction function. Then, the serving cell can obtain the predicted measurement result of the serving cell based on the time domain prediction function, and the same-frequency neighbor cell can obtain the predicted measurement result of the same-frequency neighbor cell based on the time domain prediction function.

[0139] Based on the content in the above measurement report, the behavior of the terminal device for reporting the measurement report based on the prediction function is introduced as follows:

[0140] In the embodiments of the present application, the specific implementation mode of the terminal device performing the behavior is related to the type of the measurement reporting event and the prediction function.

[0141] In a possible implementation, the measurement reporting event is an A series event, and for example, one or more of A1 event to A5 event. It should be understood that the time domain prediction function and the space domain prediction function proposed in the embodiments of the present application are applicable to the same frequency measurement, and thus the time domain prediction function and the space domain prediction function can be used in combination with the A1 event to the A5 event. The frequency domain prediction function is applicable to the different frequency measurement, and thus the frequency domain prediction function can be used in combination with the A3 event to the A5 event.

[0142] For example, Table 1 shows the behavior of a terminal device under different events and different prediction functions, where the content in the measurement report is taken as an example of RSRP.

[0143] Table 1

[0144] It should be noted that the threshold values, offset values or threshold values of various events in Table 1 are different.

[0145] As shown in Table 1, in the A1 / A2 event, for the time domain prediction function, the predicted measurement result of the serving cell can be obtained and it is determined whether it is higher / lower than the threshold value. When the duration of the event of being higher / lower than the threshold value reaches TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the serving cell; optionally, the measurement report also includes the measured value of the RSRP of the serving cell. For the space domain prediction function, since the serving cell is covered by multiple beams, the multiple beams include measured beams and predicted beams, and thus it is necessary to determine the measurement result of the serving cell according to the measured value of the measured beam and the predicted value of the predicted beam, and then determine whether the measurement result of the serving cell is higher / lower than the threshold value. When the duration of the event of being higher / lower than the threshold value reaches TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the serving cell; optionally, the measurement report also includes the index of the SSB corresponding to the measured beam of the serving cell; optionally, the measurement report also includes the measured value of the RSRP of the serving cell.

[0146] In the A3 event, for the time domain prediction function, the predicted measurement results of the serving cell and the neighbor cell can be obtained, and it is determined whether the predicted measurement result of the neighbor cell is higher than the offset value than the predicted measurement result of the serving cell. When the duration of being higher than the offset value reaches the TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the serving cell and the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the serving cell and / or the measured value of the RSRP of the neighbor cell. For the space domain prediction function, the measurement result of the neighbor cell and the measurement result of the serving cell can be obtained first, and the measurement result of the serving cell can be obtained in the manner described above in the A1 / A2 event. Then, it is determined whether the measurement result of the neighbor cell is higher than the offset value than the measurement result of the serving cell. When the duration of being higher than the offset value reaches the TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the predicted beam of the serving cell and the neighbor cell. Optionally, the measurement report can also include the index of the SSB corresponding to the measured beam of the serving cell and / or the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the measured beam of the serving cell and / or the neighbor cell, so that the network device can also determine the measurement result of the cell (i.e., the RSRP of the cell) based on the predicted value of the RSRP of the predicted beam of the cell and the measured value of the RSRP of the measured beam of the cell. For the frequency domain prediction function, according to the above content, the frequency domain prediction refers to predicting the predicted measurement result of the inter-frequency neighbor cell of a cell (e.g., the serving cell) based on the measured measurement result of the cell. Therefore, it is determined whether the predicted measurement result of the neighbor cell is higher than the first threshold value than the actual measurement result of the serving cell. When the duration of being higher than the first threshold value reaches the TTT, the measurement report can be reported. For example, the measurement report can include the measured value of the RSRP of the serving cell and the predicted value of the RSRP of the neighbor cell. It should be understood that the predicted value of the RSRP of the serving cell does not exist when the serving cell is used as the reference cell for the frequency domain prediction, and therefore cannot be reported. However, if the predicted value of the RSRP of the serving cell is obtained in some cases, it can also be reported, which is not limited in the present application.

[0147] In the A4 event, for the time domain prediction function, the prediction measurement result of the neighbor cell can be obtained, and it is determined whether the prediction measurement result of the neighbor cell is higher than a threshold value. When the duration that is higher than the threshold value reaches the TTT, the measurement report can be reported. For example, the measurement report includes the predicted value of the RSRP of the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the neighbor cell. Optionally, although the A4 event does not involve the serving cell, the terminal device can also be configured to report the actual measurement result and the prediction measurement result of the serving cell, so that the network device can know more about the signal quality of the cell, that is, the measurement report can also include the measured value and / or the predicted value of the RSRP of the serving cell. For the spatial domain prediction function, the measurement result of the neighbor cell can be obtained, and the measurement result of the neighbor cell can be obtained in the manner described above for the measurement result of the serving cell in the A1 / A2 event. Then, it is determined whether the measurement result of the neighbor cell is higher than a threshold value. When the duration that is higher than the threshold value reaches the TTT, the measurement report can be reported. For example, the measurement report includes the predicted value of the RSRP of the predicted beam of the neighbor cell. Optionally, the measurement report can also include the predicted value of the RSRP of the predicted beam of the serving cell. Optionally, the measurement report can also include the index of the SSB corresponding to the measured beam of the serving cell and / or the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the measured beam of the serving cell and / or the neighbor cell. For the frequency domain prediction function, the prediction measurement result of the neighbor cell can be obtained, and it is determined whether the prediction measurement result of the neighbor cell is higher than a threshold value. When the duration that is higher than the threshold value reaches the TTT, the measurement report can be reported. For example, the measurement report includes the predicted value of the RSRP of the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the neighbor cell and / or the neighbor cell.

[0148] In the A5 event, for the time domain prediction function, the prediction measurement result of the serving cell and the prediction measurement result of the neighbor cell can be obtained, and it is determined whether the prediction measurement result of the serving cell is lower than a first threshold value and whether the prediction measurement result of the neighbor cell is higher than a second threshold value. When the duration that simultaneously satisfies the two conditions reaches the TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the serving cell and the predicted value of the RSRP of the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the serving cell and / or the measured value of the RSRP of the neighbor cell. For the spatial domain prediction function, the measurement result of the neighbor cell and the measurement result of the serving cell can be obtained first, and the measurement result of the serving cell can be obtained in the manner described above for the measurement result of the serving cell in the A1 / A2 event. Then, it is determined whether the measurement result of the serving cell is lower than a second threshold value and whether the measurement result of the neighbor cell is higher than a third threshold value. When the duration that simultaneously satisfies the two conditions reaches the TTT, the measurement report can be reported. For example, the measurement report can include the predicted value of the RSRP of the predicted beam of the serving cell and the predicted value of the RSRP of the predicted beam of the neighbor cell. Optionally, the measurement report can also include the index of the SSB corresponding to the measured beam of the serving cell and / or the neighbor cell. Optionally, the measurement report can also include the measured value of the RSRP of the measured beam of the serving cell and / or the neighbor cell.

[0149] It should be noted that, for the time domain prediction function in the A3 / A5 event described above, the prediction measurement results of the serving cell and the neighbor cell are the prediction measurement results obtained at the same time, and thus are the prediction values at the same time. Similarly, for the spatial domain prediction function in the A3 / A5 event described above, the measurement result of the serving cell and the measurement result of the neighbor cell are the measurement results obtained at the same time. For the frequency domain prediction function in the A3 / A5 event described above, the actual measurement result of the serving cell and the prediction measurement result of the neighbor cell are obtained at the same time. In this way, when the behaviors in Table 1 are performed, time alignment can be ensured, and the correctness of the judgment can be ensured.

[0150] It can be understood that the existing A1 / A2 / A3 / A4 / A5 events can be reused to make the terminal device perform the behaviors of the terminal device in the time domain prediction function / spatial domain prediction function / frequency domain prediction function in the A1 / A2 / A3 / A4 / A5 events described above. That is, the A1 / A2 / A3 / A4 / A5 events do not need to be modified when the events are configured, and the terminal device selects the behaviors in Table 1 according to the configured events and the activated prediction functions, such as performing the behaviors of the terminal device in the second row of the second column in Table 1 when the first information is used to configure the A1 event and the activation information is used to configure the time domain prediction function, and performing the behaviors of the terminal device in the sixth row of the second column in Table 1 when the first information is used to configure the A3 event and the activation information is used to configure the frequency domain prediction function.

[0151] In another possible implementation, as can be seen from Table 1, under the time domain prediction function and the spatial domain prediction function, the two objects for which the behaviors are performed by the terminal device for judgment are either both prediction measurement results or both measurement results, that is, the two objects are aligned, and the terminal device will not make mistakes when performing the behaviors according to the configured A series events and the activated prediction functions. However, under the frequency domain prediction function of the A3 / A5 event, one of the two objects is a prediction measurement result and the other is an actual measurement result, that is, the two objects are not aligned, and the terminal device may make mistakes when performing the behaviors according to the configured A series events and the activated prediction functions.

[0152] To ensure that the terminal device uses the prediction measurement result of the neighbor cell and the actual measurement result of the serving cell for judgment, the following events can also be defined separately:

[0153] In a possible implementation, the events include a first event and / or a second event, where the first event is that the prediction measurement result of the inter-frequency neighbor cell is higher than the actual measurement result of the serving cell by a first threshold value, and the second event is that the actual measurement result of the serving cell is lower than a second threshold value and the actual measurement result of the inter-frequency neighbor cell is higher than a third threshold value.

[0154] When the first information is used to indicate the first event and / or the second event, and the frequency domain prediction function is activated, the terminal device can perform the behavior in the sixth row of the second column and / or the twelfth row of the second column in Table 1. It should be understood that the first event and / or the second event are events of the frequency domain prediction function, and the report configuration of the first event and / or the second event includes but is not limited to one or more of the threshold value (i.e., the first threshold value, the second threshold value, the third threshold value), the bias value, the hysteresis parameter, or the TTT, and the like. For details, refer to the report configuration of the A3 / A5 event.

[0155] For example, Table 2 shows the behavior of another terminal device under different events and different prediction functions:

[0156] Table 2

[0157] It should be noted that the threshold value, bias value, or threshold value of each type of event in Table 2 is different.

[0158] Based on the embodiment described in FIG. 7, the behavior of the terminal device reporting the measurement report based on the prediction function can be determined, thereby ensuring that the terminal device correctly triggers the measurement report. And the network device can make correct decisions for the subsequent mobility switching of the terminal device according to the measurement report reported by the terminal device.

[0159] In the embodiment shown in FIG. 7, the behavior of the terminal device reporting the measurement report based on the prediction function can be determined based on the following two ways:

[0160] Method 1: The network device configures the terminal device to perform the behavior.

[0161] As shown in FIG. 9, this method includes steps 901 to 905, wherein:

[0162] 901. The network device sends first information to the terminal device, and the first information is used to indicate that the terminal device measures the first measurement object and the event of the measurement report. Accordingly, the terminal device receives the first information.

[0163] 902. The network device sends activation information to the terminal device, and the activation information is used to activate the prediction function. Accordingly, the terminal device receives the activation information.

[0164] The implementation of steps 901 and 902 can refer to the implementation of step 701 described above, and will not be described here.

[0165] 903. The network device sends second information to the terminal device, and the second information is used to indicate that the measurement report is reported based on the prediction function. Accordingly, the terminal device receives the second information.

[0166] In the embodiments of the present application, the network device can configure the terminal device to report the prediction report based on the prediction function through the second information.

[0167] In a possible implementation, the second information can be carried in RRC signaling, or the second information can be carried in MAC CE signaling.

[0168] In a possible implementation, the RRC signaling carrying the second information can be the same RRC signaling as the RRC signaling carrying the first information and / or the activation information, or different RRC signaling.

[0169] In a possible implementation, the MAC CE signaling carrying the second information can be the same MAC CE signaling as the MAC CE signaling carrying the activation information, or different MAC CE signaling.

[0170] In a possible implementation, the second information and the first information and / or the activation information can be sent to the terminal device at the same time, or the second information and the first information and / or the activation information can be sent to the terminal device in sequence, and the order of sending is not limited.

[0171] For example, the second information can occupy one bit, and the bit value of "1" indicates that the measurement report is reported based on the prediction function.

[0172] Optionally, if the network device does not send the second information, the terminal device defaults to report the measurement report according to the RRM measurement mechanism without combining the AI technology, that is, only based on the actual measurement result to report the measurement report; or the bit value of "0" indicates that the measurement report is reported only based on the actual measurement result. The present application does not elaborate on the way of reporting the measurement result based on the actual measurement result.

[0173] 904, the terminal device obtains the prediction measurement result of the first measurement object based on the first information and the prediction function of the terminal device.

[0174] 905, when the prediction measurement result based on the first measurement object meets the measurement reporting event, the terminal device sends a measurement report to the network device. Correspondingly, the network device receives the measurement report.

[0175] The implementation of steps 904 and 905 can refer to the implementation of steps 702 and 703 described above, and will not be elaborated here.

[0176] Based on the embodiments described in FIG. 9, the network device can configure the behavior of the terminal device to trigger the measurement report, that is, whether to report the measurement result based on the prediction function or only based on the actual measurement result, which can further ensure the correct triggering of the measurement report.

[0177] Mode two: the terminal device selects the behavior of correctly triggering the measurement report by itself and informs the network device of the behavior selected by itself.

[0178] As shown in FIG. 10, the mode includes steps 901 to 905, wherein:

[0179] 1001. The network device sends first information to the terminal device, the first information being used to instruct the terminal device to measure a first measurement object and an event of measurement reporting. Accordingly, the terminal device receives the first information.

[0180] 1002. The network device sends activation information to the terminal device, the activation information being used to activate a prediction function. Accordingly, the terminal device receives the activation information.

[0181] The implementation mode of steps 1001 and 1002 can refer to the implementation mode of step 701 described above, and will not be described herein.

[0182] 1003. The terminal device obtains a predicted measurement result of the first measurement object based on the first information and the prediction function of the terminal device.

[0183] In the embodiments of the present application, after receiving the first information and the second information, the terminal device can select whether to report the measurement report based on the prediction function or only based on the actual measurement result.

[0184] When the terminal device selects to report the measurement report only based on the actual measurement result, the reporting can be performed according to the reporting mode in the RRM measurement mechanism without combining the AI technology.

[0185] When the terminal device selects to report the measurement report based on the prediction function, the predicted measurement result of the first measurement object can be obtained by referring to step 702 described above, and then step 1004 described below is performed.

[0186] 1004. When the predicted measurement result of the first measurement object meets the event of measurement reporting, the terminal device sends a measurement report to the network device, the measurement report including third information, the third information being used to indicate that the measurement report is reported based on the prediction function. Accordingly, the network device receives the measurement report.

[0187] The implementation mode of step 1004 can refer to the implementation mode of step 703 described above, and will not be described herein.

[0188] In the embodiments of the present application, the third information is carried by the measurement report when the measurement report is reported, to indicate that the measurement report is reported based on the prediction function. For example, the third information can occupy a single bit, and the bit takes the value of "1" to indicate that the measurement report is reported based on the prediction function. Alternatively, the third information can be the functionality ID of the prediction function. For example, assuming that the functionality ID of the time domain prediction function (01) is included in the activation information received in step 1002, the third information can also be the functionality ID of the time domain prediction function (01).

[0189] Alternatively, the third information can also not be carried in the measurement report, i.e., the third information is reported in a separate signaling associated with the measurement report, which is not limited in the present application.

[0190] Alternatively, if the terminal device selects to report the measurement report based only on the actual measurement result, it can also indicate when reporting. For example, the bit occupied by the third information takes the value of "0" to indicate that the measurement report is reported based only on the actual measurement result. Alternatively, the terminal device does not report any indication information, and the network device defaults that the received measurement report is reported based only on the actual measurement result.

[0191] Based on the embodiments described in FIG. 10, the terminal device can select whether to trigger the measurement report based on the prediction function or based only on the actual measurement result, and inform the network device or not according to the default mode, which can further ensure the correct triggering of the measurement report.

[0192] Alternatively, the embodiments shown in the above-mentioned mode one can also be combined with the embodiments shown in the mode two, i.e., after the network device configures the behavior of the terminal device, the terminal device also indicates the executed behavior to the network device. In this way, the network device can know whether the terminal device executes the configured behavior, which is beneficial to the further alignment of the network device and the terminal device on the behavior of triggering the measurement report.

[0193] Based on the above-mentioned embodiments, the network device can also monitor the performance of the prediction function of the terminal device. The specific implementation process of the monitoring mode is described below by taking the embodiment shown in FIG. 7 as an example:

[0194] As shown in FIG. 11, the monitoring mode includes steps 1101 to 1106, wherein:

[0195] 1101. The network device sends first information to the terminal device, and the first information is used to instruct the terminal device to measure the first measurement object and the event of measurement report. Correspondingly, the terminal device receives the first information.

[0196] 1102. The network device sends, to the terminal device, activation information, the activation information being used to activate the prediction function. Correspondingly, the terminal device receives the activation information.

[0197] The implementation of steps 1101 and 1102 can refer to the implementation of step 701, and details are not described herein.

[0198] 1103. The network device sends, to the terminal device, sixth information, the sixth information being used to instruct the terminal device to monitor the performance of the prediction function. Correspondingly, the terminal device receives the sixth information.

[0199] In the embodiments of the present application, the network device can configure the terminal device to monitor the performance of the prediction function through the sixth information.

[0200] In a possible implementation, the sixth information can be carried in RRC signaling. Optionally, the RRC signaling carrying the sixth information can be the same RRC signaling as the RRC signaling carrying the first information and / or the activation information, or different RRC signaling. Alternatively, the sixth information can be sent to the terminal device together with the first information and / or the activation information, or the sixth information can be sent to the terminal device before or after the first information and / or the activation information, and the order of sending is not limited.

[0201] In a possible implementation, the sixth information includes a monitoring period (T), a monitoring duration (D), and a monitoring offset. For example, the sixth information indicates that the network device configures the terminal device to perform monitoring once every T, each monitoring lasts for D, and each monitoring starts from the offset in T. For example, the monitoring time in a period can be represented as [offset, offset+D]. Alternatively, the offset can be used to determine the start time of the monitoring (or understood as the start time of T). For example, the start time of the monitoring is calculated based on the system frame number (SFN) and the offset, for example, (SFN + subframe number) mod T = offset mod T, which means that the subframe number satisfying the formula is the start time of the monitoring, wherein mod represents the modulo operation.

[0202] Optionally, the sixth information can further include the functionality ID of the prediction function. For example, the RRC signaling carrying the second information is different from the RRC signaling carrying the activation information, or the network device sends the second information and the activation information in sequence, and the second information further needs to carry the functionality ID of the prediction function to instruct the terminal device to monitor which prediction function.

[0203] Optionally, the sixth information can further include a reporting manner of the monitoring report for predicting the performance of the function, and a report configuration corresponding to the reporting manner.

[0204] Three reporting manners of the monitoring report are introduced as follows:

[0205] The first reporting manner is a periodic reporting manner.

[0206] The sixth information is used to indicate the periodic reporting of the monitoring report and a reporting period of the monitoring report.

[0207] The second reporting manner is reporting when a measurement reporting event is met.

[0208] The measurement reporting event is the measurement reporting event configured in the first information, so that the measurement reporting event configured in the first information can be reused to report the monitoring report, and signaling overhead can be saved. Specifically:

[0209] (1) reporting the monitoring report when a predicted measurement result of the first measurement object meets the measurement reporting event.

[0210] In (1), the reporting manner of the monitoring report is the same as the reporting manner of the measurement report. For example, when the predicted measurement result of the serving cell meets the threshold value for a duration of TTT (i.e., the reporting condition of the A1 event is met), the measurement report can be reported, and at this time, the monitoring report can be reported.

[0211] (2) reporting the monitoring report when an actual measurement result of the first measurement object meets the measurement reporting event.

[0212] In (2), the actual measurement result of the first measurement object needs to be obtained, and the measurement reporting event configured in the first information is reused, for example, whether the reporting condition of the event is met is determined based on only the actual measurement result of the first measurement object, and for example, when the actual measurement result of the serving cell meets the threshold value for a duration of TTT, the monitoring report can be reported.

[0213] The third reporting manner is reporting when a monitoring reporting event is met.

[0214] The monitoring reported event refers to an event triggering the monitoring report. The event is an additionally configured event, which is different from the measurement reported event configured in the first information. For example, the monitoring reported event can be a report when the prediction error is greater than or equal to a fifth threshold value, where the prediction error refers to the difference between the actual measurement result and the predicted measurement result. When the prediction is greater than or equal to the fifth threshold value, the monitoring report is reported, which can timely inform the network device that the current prediction function has poor performance, so that the network device can deactivate the prediction function. It can be understood that the event can also be in other forms, which are not limited in the present application.

[0215] It can be understood that the above-mentioned reporting manner of the monitoring report can also be a default reporting manner predefined by a protocol or factory setting. That is, the network device does not need to configure the reporting manner of the monitoring report for the terminal device, and the terminal device reports according to the default reporting manner predefined by the protocol or factory setting. For example, the default manner is (1) in the above-mentioned second manner, and the reporting is based on the above-mentioned (1).

[0216] 1104. The terminal device obtains a predicted measurement result of the first measurement object based on the first information and the prediction function of the terminal device.

[0217] The implementation manner of step 1104 can refer to the implementation manner of step 702, which is not described herein.

[0218] 1105. The terminal device sends a monitoring report of the performance of the prediction function to the network device.

[0219] The monitoring report of the performance of the prediction function is obtained within the monitoring time corresponding to the sixth information, such as [offset, offset+D]. It should be understood that if more than one monitoring is completed before triggering the monitoring report, the monitoring report reported here can include all monitoring reports obtained before triggering the monitoring report. For example, if there are two monitoring periods before triggering the monitoring report, at most two monitoring reports can be obtained, and then the two monitoring reports can be reported. Alternatively, the terminal device can be configured to report the latest obtained monitoring report each time. The present application does not limit this.

[0220] In a possible implementation manner, the monitoring report of the performance of the prediction function includes a prediction error of the first measurement object.

[0221] The prediction error of the first measurement object is determined based on the actual measurement result and the predicted measurement result of the first measurement object, and the prediction error can indicate the performance of the prediction function. For example, for the time domain prediction function, if the predicted measurement result of the first measurement object is the predicted value of the RSRP of Cell-1, the actual prediction result of the first measurement object is the measured value of the RSRP of Cell-1; for the spatial domain prediction function, if the predicted measurement result of the first measurement object includes the predicted value of the RSRP of the beam a3 of Cell-1 and the predicted value of the RSRP of the beam a4 of Cell-1, the actual measurement result of the first measurement object includes the measured value of the RSRP of the beam a3 of Cell-1 and the measured value of the RSRP of the beam a4 of Cell-1; for the spatial domain prediction function, if the prediction result of the first measurement object includes the predicted value of the RSRP of Cell-3 (Cell-3 is a frequency range neighbor of the serving cell), the actual prediction result of the first measurement object is the measured value of the RSRP of Cell-3 (obtained based on the GAP measurement).

[0222] In another possible implementation, the monitoring report of the performance of the prediction function includes the actual measurement result of the first measurement object.

[0223] As described above, when the terminal device reports the measurement report, the measurement report can include the predicted measurement result of the first measurement object, and therefore the terminal device can report the actual measurement result of the first measurement object in the monitoring report, so that the network device determines the prediction error based on the measurement report and the monitoring report.

[0224] In the embodiments of the present application, the terminal device reports the monitoring report based on the reporting manners of the above three monitoring reports, which will not be described herein.

[0225] 1106、When the predicted measurement result of the first measurement object satisfies the measurement reporting event, the terminal device sends the measurement report to the network device. Correspondingly, the network device receives the measurement report.

[0226] In the embodiments of the present application, the terminal device not only reports the measurement report based on the prediction function, but also can determine whether to send the measurement report to the network device in combination with the following two manners. The manner of reporting the measurement report based on the prediction function can refer to the description in the above embodiments.

[0227] In the first possible implementation, the terminal device stops reporting the measurement report based on the prediction function in the monitoring time determined by the sixth information. And / or reports the measurement report based on the prediction function outside the monitoring time.

[0228] For example, as shown in FIG. 12, if the time from T5 to T6 is the monitoring time, then in the time from T5 to T6, the predicted measurement result of the first measurement report can be obtained, and it can be determined whether the event of measurement reporting is met based on the predicted measurement result of the first measurement object, but any measurement report is not reported and only the monitoring report is reported; the time from T6 to T7 is outside the monitoring time (i.e., after the monitoring time ends), and the reporting of the measurement report can be resumed. Similarly, when the time from T5 to T7 is equal to the monitoring period, the time from T7 to T8 is also the monitoring time, and then in the time from T5 to T6, any measurement report is not reported and only the monitoring report is reported.

[0229] In the second possible implementation, the terminal device sends the measurement report to the network device when the performance of the prediction function indicated by the monitoring report is better than the fourth threshold, and / or does not send the measurement report to the network device when the performance of the prediction function indicated by the monitoring report is worse than the fourth threshold.

[0230] For example, the measurement report is sent to the network device when the prediction error is less than the fourth threshold, and / or the measurement report is not sent to the network device when the prediction error is greater than or equal to the fourth threshold. Since the network device is likely to make an incorrect decision based on the reported measurement report when the prediction error is large or the prediction performance is poor, resulting in an error in the mobility switching of the terminal device, the measurement report can not be reported.

[0231] It should be understood that the terminal device can also directly report the measurement report, and the network device determines whether to use the received measurement report according to the performance of the prediction function indicated by the previously received monitoring report.

[0232] Optionally, the first possible implementation can be combined with the second possible implementation. For example, in the monitoring time, the measurement report is not reported, and after the monitoring time ends, the measurement report is reported if the performance of the prediction function is better than the fourth threshold, and otherwise, the measurement report is not reported, which can save signaling overhead, and the like. Alternatively, the network device receives the monitoring report reported by the terminal device at T6, the monitoring report indicates that the performance of the prediction function is worse than the fourth threshold, and then the network device does not use or ignores all the measurement reports received from T6 to T7 until a new monitoring report reported from T7 to T8 is received, the monitoring report indicates that the performance of the prediction function is better than the fourth threshold, and then the network device can use all the measurement reports received from T6 to T7 to make a correct decision, such as a mobility management decision.

[0233] 1107. The network device sends a management instruction of the prediction function to the terminal device. Correspondingly, the terminal device receives the management instruction.

[0234] The step 1107 is an optional step. The network device can determine whether to send a management instruction of the prediction function to the terminal device according to the monitoring report received in the step 1105. For example, the management instruction includes, but is not limited to, an activation / deactivation / switching / backoff instruction of the prediction function, and the like. For example, the monitoring report indicates that the performance of the prediction function is worse than the fourth threshold, and the network device can send a deactivation instruction of the prediction function.

[0235] Based on the embodiment described in FIG. 11, on the one hand, the terminal device can correctly trigger the measurement report, and on the other hand, the network device can configure the terminal device to detect the performance of the prediction function and report the monitoring report, so as to manage the prediction function of the terminal device based on the monitoring report, and can also manage the received measurement report based on the monitoring report.

[0236] Optionally, if the network device is the O-RAN architecture shown in FIG. 6, the network device includes a RIC, a CU and a DU, and the RIC performs a task related to the prediction function. The steps 1101 to 1106 in FIG. 11 can be performed according to the embodiment shown in FIG. 13.

[0237] 1301. The CU / DU sends first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0238] The implementation of the step 1301 can refer to the implementation of the step 1101, which is not described herein.

[0239] 1302. The RIC sends first activation information to the CU / DU, and the first activation information is used to activate the prediction function of the terminal device. Correspondingly, the CU / DU receives the first activation information.

[0240] 1303. The CU / DU sends second activation information to the terminal device, and the second activation information is used to activate the prediction function. Correspondingly, the terminal device receives the second activation information.

[0241] The steps 1302 to 1303 are specific implementations of the step 1102. The bearing mode and content of the first activation information and the second activation information can refer to the description of the activation information in the above embodiments.

[0242] In the embodiment of the application, the first activation information further includes an identifier of the terminal device. For example, the first activation information includes a functionality ID of the time domain prediction function and a UE ID. In this way, the CU / DU can confirm which prediction function of the terminal device is activated.

[0243] 1304、The RIC sends first monitoring information to the CU / DU, where the first monitoring information is used to instruct monitoring of the performance of the prediction function of the terminal device. Correspondingly, the CU / DU receives the first monitoring information.

[0244] 1305、The CU / DU sends second monitoring information to the terminal device, where the second monitoring information is used to instruct monitoring of the performance of the prediction function. Correspondingly, the terminal device receives the second monitoring information.

[0245] The steps 1304 to 1305 are specific implementation manners of the step 1103. The bearing manner and content of the first monitoring information and the second monitoring information can refer to the description of the sixth information in the foregoing embodiments.

[0246] In the embodiments of the present application, the first monitoring information further includes the identifier of the terminal device. In this way, the CU / DU can confirm which terminal device needs to be monitored in terms of the prediction function.

[0247] 1306、The terminal device obtains a prediction measurement result of the first measurement object based on the first information and the prediction function of the terminal device.

[0248] 1307、The terminal device sends a monitoring report of the performance of the prediction function to the CU / DU. Correspondingly, the CU / DU receives the monitoring report.

[0249] 1308、The CU / DU sends the monitoring report of the performance of the prediction function to the RIC. Correspondingly, the RIC receives the monitoring report.

[0250] The implementation manners of the steps 1306 to 1308 can refer to the implementation manners of the steps 1104 and 1105, and details are not described herein.

[0251] 1309、When the prediction measurement result based on the first measurement object meets a measurement reporting event, the terminal device sends a measurement report to the CU / DU. Correspondingly, the CU / DU receives the measurement report.

[0252] In the embodiments of the present application, if the terminal device has / uses the capability of determining whether to send a measurement report according to the performance of the prediction function, the CU / DU only performs the forwarding function of the measurement report, that is, does not perform the step 1310, and can directly perform the step 1311 after receiving the measurement report sent by the terminal device. If the terminal device does not have / does not use the capability of determining whether to send a measurement report according to the performance of the prediction function, the CU / DU first performs the step 1310 after receiving the measurement report, and then performs the step 1311 according to the execution of the step 1310.

[0253] 1310、The CU / DU determines whether to send the measurement report.

[0254] The CU / DU can forward the measurement report to the RIC when the monitoring report indicates that the performance of the prediction function is better than a fourth threshold, and / or not forward the measurement report to the RIC when the monitoring report indicates that the performance of the prediction function is worse than the fourth threshold.

[0255] 1311. The CU / DU sends the measurement report to the RIC. Accordingly, the RIC receives the measurement report.

[0256] Based on the embodiment described in FIG. 13, most of the tasks related to the prediction function can be performed by the RIC, and the CU / DU performs a small part of the tasks related to the prediction function.

[0257] It can be understood that, in order to implement the functions in the above-described embodiments, the network device and the terminal device include the corresponding hardware structure and / or software module for performing each function. Those skilled in the art should easily realize that, in combination with the units and method steps of the examples described in the embodiments disclosed in the present application, the present application can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is implemented in hardware or computer software driven hardware depends on the specific application scenarios and design constraints of the technical solutions.

[0264] As shown in FIG. 15, the communication apparatus 1500 includes a processor 1510 and an interface circuit 1520. The processor 1510 and the interface circuit 1520 are coupled to each other. It can be understood that the interface circuit 1520 can be a transceiver or an input / output interface.
