As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0215] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected.

[0216] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, utilizing other systems for random access, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0217] Machine learning algorithms are one of the most important methods for implementing artificial intelligence technology. Machine learning can obtain models from large amounts of training data, and these models can then be used to predict events. In many fields, machine learning models can achieve very accurate prediction results.

[0218] The current research proposes AI-based mobility optimization schemes, including prediction of measurement results, prediction of handover failure (HO failure, HOF), and prediction of radio link failure (RLF). The prediction of measurement results includes both cell-level and beam-level prediction.

[0219] For mobility prediction, such as measurement result prediction, HOF prediction, RLF prediction, etc., it can currently support UE-side prediction models (UE-sided model) and network-side prediction models (NW-sided model).

[0220] For UE-sided models, the UE may need to report the prediction results of the UE-side prediction model to the network side to assist the network side in making handover decisions.

[0221] For NW-sided models, UEs may need to report some auxiliary information as input to the prediction model on the NW side. The prediction model on the NW side can make predictions based on the information reported by the UE and some information available on the NW side.

[0222] To perform AI-based predictions, the UE needs to report the inference results of its AI model or UE auxiliary information as input to the network's AI model, as required by the network. The UE may send this AI inference-related data before performing a PSCell change, but because the UE is immediately triggered by the handover or PSCell change, the target cell may not receive this inference data, potentially causing data loss. This could prevent the network from performing AI predictions or optimizing mobility based on the UE's AI prediction results, thus impacting UE performance.

[0223] Based on the aforementioned wireless communication system, various embodiments of the communication method proposed in this disclosure will be described in detail below.

[0329] In some embodiments, mobility operations may include, but are not limited to, one or more of the following mobility operations: conventional handover HO, PSCell addition, PSCell change, CHO, CPAC (conditional PSCell addition or change), LTM, DAPS, Subsequent CPC, CHO with target SCG, CHO with candidate SCG(s), etc.

[0330] Optionally, CHO refers to a handover performed by the UE when one or more handover execution conditions are met. After receiving the CHO configuration, the UE begins evaluating the execution conditions and stops evaluating them after performing a handover (including legacy handover and CHO). CHO is subject to the following criteria:

[0331] (1) CHO configuration includes CHO candidate cell configuration and execution conditions. Among them, an execution condition may contain one or two trigger conditions (e.g., CHO events A3 / A5).

[0332] Among them, CondEvent A3 (CHO event A3): The conditional reconfiguration candidate becomes better than PCell (primary cell) / PCells (primary cell group) by a certain offset.

[0333] Among them, CondEvent A5 (CHO event A5): PSCell (primary and secondary cells) becomes worse than absolute threshold 1, and the conditional reconfiguration candidate becomes better than another absolute threshold 2.

[0334] (2) If the UE receives a HO (without CHO configuration) command before any CHO execution conditions are met, the traditional HO procedure is executed, regardless of any previously received CHO configuration.

[0335] (3) When performing CHO, i.e., from the time the UE starts synchronizing with the target gNB, the UE does not monitor the source gNB (e.g., the source gNB).

[0336] Optionally, CPAC can be divided into two types: CPA and CPC. CPC refers to the PSCell change performed by the UE when the execution conditions are met. When the UE receives the CPC configuration, it begins to evaluate the execution conditions, and stops evaluating the execution conditions once a PSCell change or PCell change is triggered.

[0337] Optionally, LTM (L1 / L2 triggered mobility) refers to the gNB receiving an L1 measurement report from the UE and, based on the L1 measurement report, sending a cell handover command via the MAC CE to change the UE's serving cell. The cell handover command indicates the LTM candidate configuration, which is the LTM candidate configuration previously prepared by the gNB and provided to the UE via RRC signaling. The UE then switches to the target configuration according to the cell handover command. The LTM process can be used to reduce mobility latency.

[0338] Optionally, LTM can be divided into three types: MCG LTM (Master Cell group L1 / L2 triggered Mobility, L1 / L2 triggered handover of primary cell group mobility; MCG stands for Master Cell group), SCG LTM (Secondary Cell group L1 / L2 triggered Mobility, L1 / L2 triggered handover of secondary cell group mobility; SCG stands for Secondary Cell group), and / or LTM for MCG and SCG mobility.

[0339] For example, LTM can also be a condition-triggered LTM, which can be called any one or more of Conditional LTM, CLTM, and C-LTM.

[0678] This disclosure also provides an optional implementation scheme in which, after the UE sends inference data (UE-side AI inference results and / or network-side AI inference input data) to the source cell (old cell) and immediately performs a handover (or reconstruction), the UE retransmits this AI prediction-related information to the target cell (new cell) after accessing it. In this way, the network side can continue to optimize the UE's performance based on AI prediction based on this information.

[0679] 1. If the UE has sent prediction-related information (which can correspond to the second prediction-related information mentioned above) before accessing the first cell, in response to the UE accessing the first cell, the UE sends prediction-related information (which can correspond to the first prediction-related information mentioned above) to the first cell.

[0697] 5.2.2 For example, if the UE sent prediction-related information to the second cell via prediction information transmission message before accessing the first cell, then the UE will send prediction-related information to the first cell via prediction information transmission message after accessing the first cell.

[0698] 6. Based on any one of 1-5, and based on network indications or protocol provisions, the UE determines whether to send prediction-related information to the first cell.

[0699] The network indication information described in 6.1 can instruct the UE to send prediction-related information for a specific AI prediction function;
