Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0185] In some embodiments, machine learning algorithms are one of the most important implementation methods of artificial intelligence technology. Machine learning can generate models from large amounts of training data, which can then be used to predict events. In many fields, models trained using machine learning can produce highly accurate predictions.

[0186] In some embodiments, in order to support Layer 3 (L3) mobility, the network side will configure RRM (Radio Resource Management) measurements for the UE, and the network can trigger switching based on the measurement results reported by the UE. The mobility driven by the "Cell" level RRC (Radio Resource Control) is called "L3 mobility" in the physical layer. In some embodiments, the current L3 measurement report can include cell-level measurement results and beam-level measurement results. Based on the UE's measurement report, the network can determine the target cell for switching and the best beam for the UE to access. After the target cell and / or beam are confirmed, a switching command (Reconfiguration with sync) is sent to the UE. The command carries the configuration information of a target cell, which may include bearer configuration, MAC configuration and random access configuration. After receiving the switching command, the UE will synchronize with the target cell, then initiate a random access process to access the target cell, and start using the carried target cell configuration.

[0187] In some embodiments, the current L3 handover mechanism triggers and executes handovers based on reported historical measurement results and / or measurement events, making it a reactive approach. This approach may perform well in existing macrocell low-mobility scenarios. However, when UE mobility is high, in high-density deployments, or when mobility is required for both existing and future services (such as Extended Reality), this reactive approach can present challenges, such as increased handover failures, radio link failures, ping-pong handovers, throughput loss, or premature / late handover requests. To improve handover robustness, Rel-16 introduced conditional handover. To reduce the interruption time associated with frequent handovers between small cells, Rel-18 introduced LTM HO. However, these two mechanisms are insufficient, as they remain reactive by design. On the other hand, mechanisms based on AI / ML (Machine Learning) algorithms have the potential to enable proactive solutions. Therefore, in Rel-19, 3GPP decided to investigate AI-based mobility optimization solutions that incorporate beam-level measurement prediction. LTM refers to L1 / L2-Triggered Mobility (LTM). HO stands for Handover.

[0188] In some embodiments, the potential benefits and advantages of AI / ML-assisted mobility based on network-triggered L3 handover are studied and evaluated, considering the following aspects: AI / ML-based RRM measurement and event prediction; cell-level measurement prediction, including intra-frequency and inter-frequency (UE-side and NW (Network) side models) [RAN2]; inter-cell beam-level measurement prediction for L3 mobility (UE-side and NW-side models) [RAN2].

[0189] In some embodiments, in Rel-19, Inter-cell Beam-level measurement prediction can be deployed on the UE side or on the network side.

[0190] In some embodiments, inter-cell beam-level measurement prediction can be divided into spatial domain prediction and time domain prediction. Spatial domain prediction can effectively reduce measurements, and time domain prediction can predict future beam-level measurement results, making it easier to predict in advance which beam will be more suitable for UE access in the future.

[0191] In some embodiments, in the Random Access Resource selection during the handover process, in the beam selection process of the existing handover process, the UE needs to select a beam based on the dedicated CFRA resources configured by the network or select a beam based on the CBRA criteria.

[0192] In some embodiments, the random access procedure during handover is as follows:

[0193] Handover is an action taken by connected UEs. Before initiating a handover command, the source base station (gNB) has already obtained the random access resource configuration for the target cell and the C-RNTI of the target cell assigned to the UE. After receiving the handover command from the base station, the UE initiates random access in the target cell based on the configuration information in the handover command. This process is a random access procedure triggered by the RRC layer. The random access-related parameters in the handover command sent by the gNB to the UE mainly include: the synchronization signal block (SSB) or CSI-RS used for downlink measurement and associated with the PRACH resource, the RSRP (Reference Signal Receiving Power) threshold of the SSB or CSI-RS, the dedicated preamble code for non-contention random access, and the C-RNTI of the UE in the target cell. In addition, NR introduces a priority random access mechanism for handovers, allowing the gNB to assign different power ramp parameters and backoff factors to the handovering UE than to general UEs [3-4].

[0194] In some embodiments, the handover may adopt a non-contention random access method or a contention random access method. The conditions for the UE to initiate a non-contention random access procedure are as follows.

[0195] The gNB allocates a dedicated preamble code to the UE: The gNB allocates multiple sets of SSBs or CSI-RS and corresponding dedicated preamble codes to the UE. The UE measures these SSBs or CSI-RS and obtains the SSBs or CSI-RSs whose measured RSRP is greater than the RSRP threshold. It then selects one of these SSBs or CSI-RSs and initiates random access using the corresponding dedicated preamble code.

[0196] Allocate dedicated PRACH resources: random access channel resources corresponding to the above-mentioned SSB or CSI-RS.

[0197] In some embodiments, referring to the contention-based random access (CBRA) process illustrated in Figures 1B and 1C and the contention-free random access (CFRA) process illustrated in Figures 1D and 1E , each random access attempt by the UE in a complete random access process begins with random access resource selection. If the UE cannot obtain non-contention random access resources, it initiates contention random access. Because the NR system uses multi-beam transmission, the channel states of different beams vary, and a handover UE may switch between non-contention random access and contention random access.

[0198] In some embodiments, as can be seen from the above, the prediction of the beam-level measurement results of the neighboring cells can assist in the beam selection during the switching process, and the NW side can configure a more suitable beam for the UE based on the beam-level measurement results of the neighboring cells. Although both the UE side and the network side can predict the beam-level measurement results, prediction on the UE side can better obtain and learn the information specific to the UE side, and can well avoid privacy and security issues. The UE can report the predicted beam-level measurement results of the neighboring cells to the network, so that the network can determine the beam of the target cell based on the predicted results. However, how the UE performs the prediction and reporting of the beam-level measurement results based on AI has not yet been discussed, and there are no clear guidelines for the required network configuration and execution methods.

[0199] In view of this, the embodiments of the present disclosure propose a communication method, terminal, network device, communication system and storage medium, which can support better mobility management on the NW side based on the predicted beam-level measurement results of neighboring cells reported by UE, and clarify the configuration and reporting criteria of the neighboring cell beam-level measurement prediction.

[0580] In some embodiments, embodiment 1, based on the configuration of the network, the UE performs prediction of the beam-level measurement results of the neighboring cells.

[0582] In Example 2, based on Example 1, the network configuration in Example 1 includes one or more of the following information:

[0583] Optionally, in 2.1, the UE needs to perform prediction in the time domain or the spatial domain;

[0593] Optionally, in 2.5.2, for example, the network side may configure the UE to predict the measurement result of beam 3 of cell 2 based on the (actual) measurement result of beam 2 of cell 1;

[0594] Optionally, in 2.6, the predicted quantity corresponding to the beam-level measurement result that the UE needs to predict may be one or more of the following:

[0595] Optionally, 2.6.1, RSRP

[0596] Optionally, 2.6.2, RSRQ

[0599] Optionally, 2.6.5, the identifier of the strongest beam of a neighboring cell, or the identifiers of the strongest n beams.

[0600] In embodiment 3, based on embodiment 1 or 2, the UE determines to activate / deactivate the beam measurement result prediction of the neighboring cell based on an indication from the network side (physical layer message, MAC layer message or RRC message).

[0601] Optionally, 3.1, for example, the network can activate the prediction of the beam measurement results of the neighboring cells through MAC CE, for example, the configuration information described in 2 pre-configured to the UE by the NW side to perform the prediction of the beam measurement results of the neighboring cells.

[0614] In embodiment 6, the UE may report the prediction result once or multiple times based on a network request, or may report the prediction result periodically or periodically.

[0615] Example 7: Based on this, the network side can generate a corresponding switching target cell configuration for the UE based on the beam-level measurement results of the predicted neighboring area reported by the UE. The switching target cell configuration can indicate the beam that the UE can choose to access.

[0616] Optionally, 7.1. Exemplarily, the beam that the above-mentioned UE can select to access can be included in the RACH configuration.

[0619] In Example 8, the source gNB (the base station corresponding to the source access cell) can also directly instruct the UE to access the beam corresponding to the target cell through MAC CE or PDCCH, for example, indicating the SSB index or the corresponding CSI-RS index. The source gNB can send this message to the UE before or when sending the handover command. This message can also include the corresponding target cell configuration identifier.

[0620] In Example 9, in order to support the above configuration (referring to the configuration in Examples 7 and 8), after receiving the predicted beam measurement results of the UE, the source gNB forwards them to the target gNB (the base station corresponding to the target cell), so that the target gNB can generate the configuration in Example 7.

[0621] Optionally, in 9.1, the source gNB may send the predicted beam measurement result to the target gNB via a handover request message.

[0622] Optionally, in 9.2, the source gNB may also include the predicted beam measurement results in a HandoverPreparationInformation message and send it to the target gNB via a handover request message.

[0623] Optionally, in 9.3, the source gNB may also send only the predicted beam measurement results corresponding to the handover target cell (see Example 4).

[0627] Optionally, 9.3.4, etc.

[0628] Example 10: Based on Example 2, one or more of the predicted configurations described in Example 2 can be generated by the target cell or by the serving cell.

[0629] Optionally, in 10.1, if the target cell generates the configuration, the source gNB may request the target gNB to generate the corresponding configuration before sending the handover request, and then the source gNB sends the configuration provided by the target gNB to the UE.

[0630] Example 11: Based on 1-15, UE capability 1 is introduced. The UE capability is used to indicate that the UE can perform UE-side beam-level measurement result prediction. The UE can report capability 1 to indicate that the UE supports beam-level measurement result prediction, and the network side can configure related configurations for the UE. Capability 1 can indicate that the UE supports time domain prediction and / or spatial domain prediction.

[0631] Example 12: Based on 1-15, UE capability 2 is introduced. The UE capability is used to indicate that the UE can report predicted beam-level measurement results. UE capabilities 1 and 2 in 16 and 17 may be the same UE capability. If they are different UE capabilities, the UE must support capability 1 if it supports capability 2. If the UE can report capability 2, indicating that the UE supports reporting predicted beam-level measurement results, the network side may configure relevant configurations for the UE.

[0632] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0633] The above embodiments of the present disclosure can support the NW side to perform mobility management based on the predicted neighboring cell beam-level results reported by the UE, and clarify the configuration and reporting criteria of the neighboring cell beam-level measurement prediction.
