The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.
[0197] In some embodiments, the core network device may be a single device, or may be multiple devices or a group of devices. The core network may include at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).
[0198] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.
[0199] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are examples. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0200] The embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (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 communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).
[0201] In some embodiments of the present disclosure, mobility-related big data is used for training, and the resulting AI model can predict whether a wireless link failure occurs based on the UE's network environment.
[0202] In some embodiments, mobility can be enhanced in RRC_CONNECTED mode by following the existing mobility framework, i.e., the handover decision is always made on the network side. The mobility use case focuses on independent NR primary serving cell (PCell) changes, and artificial intelligence / machine learning (AI / ML) models on the UE side and the network side can be considered separately. AI / ML-assisted mobility in network-triggered L3-based handovers can include at least one of the following:
[0203] AI / ML-based Radio Resource Management (RRM) measurement and event prediction;
[0204] Cell-level measurement prediction, including intra-frequency and inter-frequency prediction (the model can be UE-side and network-side models);
[0205] Inter-cell beam-level measurement prediction for L3 mobility (the models can be both UE-side and network-side models);
[0206] Handover (HO) failure / Radio Link Failure (RLF) prediction (the model may be a UE-side model);
[0207] Measurement event prediction (the model may be a UE-side model).
[0208] In some embodiments, the UE's Radio Resource Control (RRC) layer starts a T310 timer after receiving N310 consecutive out-of-sync indications. If the T310 timer expires, an RLF is triggered. If N311 consecutive in-sync indications are received while the T310 timer is running, the T310 timer is stopped.
[0209] In some embodiments, the UE needs to start the T310 timer based on multiple N310 out-of-sync indications, and only after T310 times out will it determine that a wireless link failure has occurred. After determining that a wireless link failure has occurred, the UE can start the failure recovery process. During this period, the UE may not be able to maintain communication with the network, resulting in service interruption.
[0210] FIG2A is an interactive diagram illustrating an information reporting method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system. As shown in FIG2A , the method may include:
[0211] Step S2101: The terminal device predicts the wireless link and obtains prediction information.
[0212] In some embodiments, the prediction information may include any of the following:
[0213] A wireless link failure occurs in the wireless link;
[0214] No radio link failure occurs on the radio link.
[0215] In some embodiments, the terminal device may predict the wireless link to obtain a first probability of wireless link failure; determine that the first probability is greater than a first threshold, and determine that wireless link failure occurs in the wireless link.
[0216] In some embodiments, the terminal device may predict the wireless link to obtain a first probability of wireless link failure in the wireless link; determine that the first probability is less than a second threshold, and determine that wireless link failure does not occur in the wireless link.
[0217] In some embodiments, the second threshold may be the first threshold or a third threshold, and the third threshold is smaller than the first threshold.
[0218] In one implementation, if the first probability is greater than a first threshold, it can be determined that a radio link failure occurs in the radio link; if the first probability is less than the first threshold, it can be determined that a radio link failure does not occur in the radio link.
[0219] In one implementation, if the first probability is greater than a first threshold, it can be determined that radio link failure occurs in the radio link; if the first probability is less than a third threshold, it can be determined that radio link failure does not occur in the radio link.
[0220] In some embodiments, “radio link failure occurs in the wireless link” can be understood as “radio link failure may occur in the wireless link”, and “radio link does not fail in the wireless link” can be understood as “radio link will not fail in the wireless link”.
[0221] In some embodiments, “radio link failure occurs in the radio link” can be understood as “radio link failure occurs in the radio link at the current moment”, or “radio link failure occurs in the radio link at a certain time in the future”, or “radio link failure occurs in the radio link at a certain time period in the future”. Similarly, “no radio link failure occurs in the radio link” can be understood as “no radio link failure occurs in the radio link at the current moment”, or “no radio link failure occurs in the radio link at a certain time period in the future”, or “no radio link failure occurs in the radio link at a certain time period in the future”.
[0222] In some embodiments, the “first probability” may also be referred to as a “first confidence level”.
[0223] In some embodiments, the first probability may be the probability of a single prediction, the average probability of multiple predictions, or the average probability of a period, which is not limited in the embodiments of the present disclosure.
[0224] In some embodiments, the terminal device may predict the wireless link based on the third information to obtain the prediction information.
[0225] In some embodiments, the third information may also be information determined autonomously by the terminal device, that is, the terminal device may autonomously predict the wireless link.
[0226] In some embodiments, the third information may include at least one of the following:
[0227] First configuration information, where the first configuration information may be information configured by the network device for predicting a wireless link;
[0228] The first rule may be a protocol agreement.
[0229] In some embodiments, the first configuration information may include at least one of the following:
[0230] A prediction start time, where the prediction start time is a start time for predicting whether a radio link failure occurs on the radio link;
[0231] Prediction end time, where the prediction end time is the end time when it is necessary to predict whether the wireless link will fail;
[0232] A prediction time range, where the prediction time range is a time range for predicting whether a radio link failure occurs in the radio link;
[0233] Prediction duration, where the prediction duration is the duration required to predict whether a radio link failure occurs on the radio link;
[0234] a first threshold, where the first threshold is used to determine whether a radio link failure occurs in the radio link;
[0235] a third threshold, where the third threshold is used to determine whether a radio link failure occurs in the radio link, and the third threshold is less than, equal to, or greater than the first threshold;
[0236] Predicting start-up conditions;
[0237] The start time, forecast duration, and forecast interval of periodic forecasts.
[0238] In some embodiments, the “end time of the radio link failure” may also be referred to as the “cutoff time of the radio link failure.” For example, the time range of the radio link failure is from time A to time B, and time B is the predicted end time.
[0239] In some embodiments, when the first configuration information does not include the predicted start time, ie, the start time of the radio link failure, the current time may be used as the start time of the radio link failure.
[0240] It should be noted that the predicted start time may also be other time agreed upon in the protocol, and the embodiments of the present disclosure are not limited to this.
[0241] In some embodiments, the predicted time range is a time period between a predicted start time and a predicted end time.
[0242] In some embodiments, the "prediction time range" may also be referred to as a "prediction time window", "predicted duration of the radio link RLF", etc.
[0243] In some embodiments, the “prediction duration” may be used to indicate the duration for which the UE predicts whether a radio link failure occurs in the radio link.
[0244] In some embodiments, the "predicted time range" and "predicted duration" may be represented by a timer duration. The start time of the timer may be the predicted start time configured by the network, the time when the terminal device receives the first configuration, the predicted time when the radio link is activated, or a time determined by the terminal device based on implementation or protocol specifications.
[0245] In some embodiments, the predicted start time, the predicted end time, the predicted time range, and the predicted duration may be Coordinated Universal Time (UTC) time, a System Frame Number (SFN), or a time slot, which is not limited in the embodiments of the present disclosure.
[0246] In some embodiments, the predicted end time may be UTC time, SFN, or slot, which is not limited in the embodiments of the present disclosure.
[0247] In some embodiments, if the predicted time range is not included in the first configuration information, the terminal device can predict the longest possible duration based on the performance of the AI model, or it can automatically determine the predicted duration, or it can determine the predicted duration according to the protocol agreement.
[0248] In some embodiments, the first threshold may be used to determine whether a radio link failure occurs in the radio link.
[0249] In one implementation, if it is determined that the first probability is greater than the first threshold, it can be determined that a radio link failure occurs in the radio link; if it is determined that the first probability is less than or equal to the first threshold, it can be determined that no radio link failure occurs in the radio link.
[0250] In some embodiments, the first threshold may be a threshold for determining that a radio link failure occurs in the radio link, and the third threshold may be a threshold for determining that a radio link failure does not occur in the radio link.
[0251] In one implementation, if it is determined that the first probability is greater than the first threshold, it can be determined that a radio link failure has occurred in the radio link; if it is determined that the first probability is less than or equal to the first threshold, it cannot be determined that a radio link failure has not occurred in the radio link. If it is determined that the first probability is less than the third threshold, it can be determined that a radio link failure has not occurred in the radio link.
[0252] In some embodiments, if the terminal device determines that the prediction start condition is met, the prediction of the wireless link may be started; if the terminal device determines that the prediction start condition is not met, the prediction of the wireless link may not be started.
[0253] In some embodiments, the predicted activation condition may be determined based on measurement results of the serving cell.
[0254] In one implementation, the prediction start condition may be that the measurement result of the serving cell is less than a threshold value. For example, the threshold value may be 1. If the measurement result of the serving cell is less than 1, it may be determined that the prediction start condition is met.
[0255] In another implementation, the prediction initiation condition may be receiving the Nth out-of-sync indication from the lower layer, for example, N may be N310.
[0256] In some embodiments, the network device may instruct the terminal device to perform periodic predictions on the wireless link.
[0257] In some embodiments, the start time of the periodic prediction may be UTC time, SFN, or slot, which is not limited in the embodiments of the present disclosure.
[0258] In some embodiments, the prediction duration of the periodic prediction may be the duration of each periodic prediction of whether a radio link failure occurs. For example, if the prediction duration is T s, the terminal device may predict whether a radio link failure occurs within T s.
[0259] In some embodiments, the prediction interval of periodic prediction can be understood as "how often a radio link prediction is performed." For example, if the prediction interval is R s, the terminal device can initiate a radio link prediction every R s. For another example, if the prediction duration is T s, the terminal device can initiate a radio link prediction every R s and predict whether a radio link failure will occur within the next T s.
[0260] In some embodiments, the first configuration information may include first indication information, and the first indication information may be used to indicate at least one of the following:
[0261] prediction of activated radio links;
[0262] prediction of deactivating wireless links;
[0263] Activate the reporting of prediction results;
[0264] Deactivate the reporting of prediction results.
[0265] In some embodiments, “activating prediction of a wireless link” may be understood as “allowing a terminal device to predict a wireless link”.
[0266] In some embodiments, “deactivating the prediction of the radio link” may be understood as “not allowing the terminal device to predict the radio link”.
[0267] In some embodiments, “activating reporting of prediction results” can be understood as “allowing the terminal device to report prediction results to the network device”.
[0268] In some embodiments, “deactivating reporting of prediction results” may be understood as “not allowing the terminal device to report prediction results to the network device”.
[0269] In some embodiments, the “prediction of a wireless link” may be a prediction of whether a wireless link failure occurs in the wireless link.
[0270] In some embodiments, “reporting of prediction results” may include reporting the prediction results to the network device after obtaining prediction information of whether a radio link failure occurs in the radio link.
[0271] In some embodiments, the first indication information may be one or more of PHY, MAC layer, and RRC layer signaling. For example, the network device may activate or deactivate the prediction of radio link failure through a medium access control control element (MAC CE), or activate or deactivate the reporting of the prediction result through a MAC CE.
[0272] In some embodiments, the first rule includes at least one of the following:
[0273] When the T310 timer starts running, the wireless link is predicted;
[0274] When receiving the first out-of-sync indication from the lower layer, the wireless link is predicted;
[0275] When the Nth out-of-sync indication from the lower layer is received, the wireless link is predicted.
[0276] In some embodiments, when the T310 timer starts running, the terminal device may start predicting the wireless link.
[0277] In some embodiments, when the terminal device receives the first out-of-sync indication from the lower layer, the prediction of the radio link may be initiated.
[0278] In some embodiments, when the terminal device receives Nxx out-of-sync indications from the lower layer, it may start predicting the wireless link.
[0279] In some embodiments, Nxx may be configured by a network device, may be agreed upon by a protocol, or may be pre-configured by a terminal device, and this disclosure does not limit this.
[0280] In some embodiments, the terminal device can predict the wireless link through an AI model based on the third information to obtain the prediction information.
[0281] In some embodiments, the terminal device may make a one-time prediction of the wireless link or may make a periodic prediction of the wireless link.
[0282] In some embodiments, the AI model may be located on the terminal device side, for example, the AI model may be located on an OTT (Over the Top, via the Internet) server.
[0283] In some embodiments, if dual connectivity (DC) is configured, the terminal device may perform RLF prediction on the PCell and may also perform RLF prediction on the primary secondary cell (PSCell).
[0284] In some embodiments, it is determined that the terminal device has a first capability, and the first capability is to support prediction of the wireless link; the wireless link is predicted to obtain the prediction information.
[0285] In one implementation, if the terminal device can predict the radio link, the radio link can be predicted, and the network device can configure information for the terminal device for the radio link prediction. For example, the network device can send first configuration information to the terminal device.
[0286] In some embodiments, "the terminal device supports the prediction of the wireless link" can be understood as "the terminal device side is configured with an AI model for wireless link prediction", or "the AI model for wireless link prediction configured on the terminal device side is in an activated state".
[0287] Step S2102: The terminal device determines that the prediction information indicates that a wireless link failure has occurred in the wireless link.
[0288] In some embodiments, the terminal device obtains a first probability based on the prediction, and if it is determined that the first probability is greater than a first threshold, it is determined that the prediction information is that a radio link failure occurs in the radio link.
[0289] Step S2103: The terminal device reports the prediction result to the network device through the second information.
[0290] In some embodiments, if it is determined that a wireless link failure occurs in the wireless link, the prediction result may include at least one of the following:
[0291] second indication information, where the second indication information is used to indicate that the prediction information is obtained through prediction;
[0292] third indication information, where the third indication information is used to indicate that a radio link failure occurs on the radio link;
[0293] The identification of the serving cell;
[0294] Fourth indication information, where the fourth indication information is used to indicate a time when a radio link failure occurs in the radio link;
[0295] Fifth indication information, where the fifth indication information is used to indicate at least one candidate target cell to which the terminal device can be switched;
[0296] The sixth indication information is used to indicate a measurement result of at least one cell.
[0297] In some embodiments, the fourth indication information may be the predicted time when a radio link failure occurs in the radio link.
[0298] In some embodiments, the fifth indication information may include a target cell or a list of target cells recommended for switching by the terminal device.
[0299] In some embodiments, the target cell or the list of target cells may be indicated by a cell identification (ID).
[0300] In some embodiments, the sixth indication information may include measurement results of the serving cell and / or at least one neighboring cell.
[0301] In one implementation, the measurement result of the cell may be a measurement result actually obtained by the terminal device.
[0302] In another implementation, the measurement result of the cell may be a measurement result predicted by the terminal device based on an AI model.
[0303] In some embodiments, the time when the radio link failure occurs in the radio link indicated by the fourth indication information can be a time range, that is, a period of time, or a time point, that is, a time.
[0304] In some embodiments, the fourth indication information can be expressed by UTC time or by duration. For example, the fourth indication information can indicate how long it will take for RLF to occur. It can also be expressed by SFN, slot, symbol, etc. The embodiments of the present disclosure do not limit this.
[0305] In some embodiments, if there are multiple candidate target cells to which the terminal device can switch, the multiple target cells can be represented by a target cell list.
[0306] In some embodiments, the measurement result of the at least one cell indicated by the sixth indication information may be the measurement result of the at least one candidate target cell indicated by the fifth indication information.
[0307] In some embodiments, the measurement result may include at least one of the following: Reference Signal Receiving Power (RSRP), Reference Signal Received Quality (RSRQ), Signal to Interference plus Noise Ratio (SINR), and the reference signal corresponding to the measurement result may be a synchronization signal block (SSB) and / or a channel state information reference signal (CSI-RS).
[0308] It should be noted that the AI model used for measurement result prediction may be different from the AI model used for wireless link prediction.
[0309] For example, the terminal device can report that a wireless link failure is detected at 1 minute and 10 seconds UTC time (or SFN x, or Slot m of SFN x), and recommend neighboring cell 1 as the target cell for switching, carrying the RSRP of neighboring cell 1.
[0310] In some embodiments, the second information may include at least one of the following: physical layer (PHY) information, medium access control (MAC) information, and radio resource control (RRC) message.
[0311] For example, the prediction result may be carried in at least one of physical layer information, MAC information, and RRC information.
[0312] In one implementation, the prediction result may be reported to the network device via a measurement report. For example, the prediction result may be carried in the measurement report.
[0313] In another implementation, the prediction result may be reported to the network device via UE assistance information.
[0314] In another implementation, the prediction result may be carried in relevant information such as Self-Organizing Network (SON) or Minimization Drive Test (MDT) and reported to the network device.
[0315] It should be noted that the prediction result may also be carried in other messages sent by the terminal device to the network device, and this embodiment of the present disclosure does not limit this.
[0316] In some embodiments, it is determined that a radio link failure occurs in the PCell, and the prediction result is reported to the network device via the PSCell.
[0317] In other embodiments, it is determined that a radio link failure occurs in the PSCell, and the prediction result is reported to the network device via the PCell.
[0318] In some embodiments, determining that a radio link failure occurs in the PCell may be obtained by the terminal device predicting the radio link of the PCell.
[0319] In some embodiments, determining that a radio link failure occurs in the PSCell may be obtained by the terminal device predicting the radio link of the PSCell.
[0320] For example, if the terminal device predicts the wireless link of the PCell and determines that the wireless link has failed, the prediction result can be reported to the network device through the PSCell; if the terminal device predicts the wireless link of the PSCell and determines that the wireless link has failed, the prediction result can be reported to the network device through the PCell.
[0321] In some embodiments, the terminal device may carry the prediction result in MCG Failure information or SCG Failure information and report it to the network device.
[0322] In some embodiments, reporting the prediction result to the network device includes at least one of the following:
[0323] Periodically reporting the prediction result to the network device;
[0324] Reporting the prediction result to the network device according to first information, where the first information is information sent by the network device to request reporting of the prediction result;
[0325] Determine that the first condition is met, and report the prediction result to the network device.
[0326] In some embodiments, if the terminal device periodically predicts the wireless link, the prediction result may be periodically reported to the network device.
[0327] In some embodiments, the period for the terminal device to report the prediction results to the network device may be the same as or different from the period for performing wireless link prediction, and this is not limited in the embodiments of the present disclosure.
[0328] In some embodiments, the network device may send the first information to the terminal device, and after receiving the first information, the terminal device reports the prediction result to the network device.
[0329] In some embodiments, the network device may request the UE to report the prediction result by sending a PHY, MAC or RRC message.
[0330] In some embodiments, the first condition may include at least one of the following:
[0331] A wireless link failure occurs in the wireless link;
[0332] The measurement result of the serving cell is less than the fourth threshold;
[0333] The probability of radio link failure occurring in the radio link is greater than a fifth threshold.
[0334] In some embodiments, "radio link failure occurs in the radio link" can be understood as "the terminal device predicts RLF".
[0335] In some embodiments, the "probability of radio link failure occurring" may also be referred to as a "confidence value of radio link failure occurring".
[0336] For example, if the terminal device predicts RLF, it can report the prediction result to the network device; for another example, if the terminal device determines that the measurement result of the service cell is less than the fourth threshold (for example, 2), it can report the prediction result to the network device; for another example, if the terminal device determines that the probability of radio link failure in the wireless link is greater than the fifth threshold, it can report the prediction result to the network device.
[0337] In some embodiments, the first condition may be configured by the network device, agreed upon by the protocol, or determined autonomously by the terminal device, which is not limited in the embodiments of the present disclosure.
[0338] In some embodiments, the terminal device may report the prediction result to the network device based on the second configuration information.
[0339] In some embodiments, the second configuration information may include at least one of the following: a reporting period, and a first condition.
[0340] In some embodiments, the reporting period may be configured by the network device, may be agreed upon by the protocol, or may be determined autonomously by the terminal device, which is not limited in the embodiments of the present disclosure.
[0341] In one implementation, the terminal device may report the prediction result to the network device according to the reporting period.
[0342] In another implementation, the terminal device may report the prediction result to the network device when determining that the first condition is met.
[0343] In another implementation, the terminal device may determine whether the first condition is met in each reporting period, and if the first condition is met, report the prediction result to the network device.
[0344] In some embodiments, it is determined that the terminal device has a second capability, and the second capability is to support reporting the prediction result; based on the prediction information, the prediction result is reported to the network device.
[0345] In one implementation, if the terminal device can report the radio link, the second capability can be reported to the network device, and the network device can configure information for the terminal device to report the radio link. For example, the network device can send the second configuration information to the terminal device.
[0346] It should be noted that if the terminal device has the second capability, it can be determined that the terminal device has the first capability. In other words, when the terminal device has the second capability, it also has the first capability, that is, when the terminal device supports reporting prediction results, it also supports wireless link prediction.
[0347] In some embodiments, it is determined that the terminal device reports the prediction result and the prediction of the wireless link is stopped.
[0348] In some embodiments, it is determined that the terminal device reports the prediction result or starts the prediction of the wireless link, and the T310 timer is controlled to stop timing.
[0349] In one implementation, if the terminal device triggers reporting of the prediction result, the prediction of the radio link may be stopped. For example, the periodic prediction of the radio link may be stopped.
[0350] In another implementation, if the terminal device triggers reporting of the prediction result, or starts RLF prediction, the timing of the T310 timer can be stopped.
[0351] By adopting the above method, when it is determined that a wireless link will fail, the prediction result is reported to the network device, so that the network device can initiate a switch in time to avoid service interruption, thereby improving network performance.

[0515] The optional implementation of step S5101 can refer to the optional implementation of steps S2101 to S2102 in Figure 2A, steps S3101 to S3102 in Figure 3A, and other related parts in the embodiments involved in Figures 2A and 3A, which will not be repeated here.

[0518] In some embodiments, the above method may include the method described in the embodiments of the above communication system, terminal equipment, network equipment, etc., which will not be repeated here.
[0519] In some embodiments of the present disclosure, a method for reporting information is provided, which may include at least one of the following embodiments:
[0520] Example 1: UE starts prediction of radio link failure, predicts whether link failure will occur, obtains prediction results, and / or reports prediction results
[0521] Exemplarily, the prediction is provided by AI, and the AI model can be located on the UE side, such as an OTT server.
[0522] Exemplarily, the prediction of the radio link failure may be an RLF prediction for the PCell, or an RLF prediction for the PSCell, if DC is configured.
[0523] Example 2: Based on Example 1, the reported prediction result can be used to indicate whether the UE will experience a radio link failure or not.
[0524] Embodiment 3, based on embodiment 1 or 2, in response to the UE predicting that a radio link failure will occur, the reported prediction result includes but is not limited to one or more of the following information:
[0525] Indication information, indicating that the relevant information reported is generated by the prediction;
[0526] Radio link failure indication;
[0527] Serving cell identifier;
[0528] Wireless link failure trigger time (based on the predicted future time);
[0529] The recommended handover target cell or target cell list may be indicated by cell ID;
[0530] Measurement results of one or more neighboring cells, such as the measurement results of the recommended handover target cell / target cell list.
[0531] For example, the measurement result of the neighboring area may be a real measurement result, or a prediction result based on AI prediction (different from the AI model in Example 1).
[0532] For example, the UE reports that the UE detects a radio link failure at 1 minute and 10 seconds UTC time (or SFN x, or Slot m of SFN x), and recommends neighboring cell 1 as the target cell for handover, carrying the RSRP of neighboring cell 1.
[0533] Embodiment 4: Based on embodiment 1 or 2, in response to the UE predicting that no radio link failure will occur in the future, prediction result reporting is not triggered.
[0534] Embodiment 5, based on embodiment 1 or 2, in response to the UE predicting that radio link failure will not occur in the future, the reported prediction result includes but is not limited to one or more of the following information:
[0535] Indication information, indicating that the relevant information reported is generated by the prediction;
[0536] No indication of radio link failure occurs;
[0537] Serving cell identifier;
[0538] The effective time range and duration (or time window) corresponding to the prediction result;
[0539] For example, the UE may report that no radio link failure will occur within the next 10 minutes;
[0540] For example, if the UE can obtain the UTC time, the UE may report that the radio link failure will not occur before 10:05 UTC time;
[0541] For example, if the UE can obtain the UTC time, the UE may report that no radio link failure will occur between 10:00 and 10:05 UTC time;
[0542] For example, the UE may report that RLF will not occur before system frame SFN 1, or the UE may report that RLF will not occur between SFN x and SFN y, where the SFN is the SFN corresponding to the current serving PCell.
[0543] Example 6: The UE determines that a link failure will occur based on the predicted probability or confidence value of link failure being greater than a first threshold; and determines that a link failure will not occur based on the predicted probability or confidence value of link failure being less than a second threshold. The first threshold may be equal to the second threshold.
[0544] Example 7: The UE may report the prediction result periodically, or based on a network request, or based on an event trigger.
[0545] Exemplarily, based on the network configuration, RLF prediction is periodically started and the prediction results are reported.
[0546] Exemplarily, the network device may request the UE to report the prediction result by sending a PHY, MAC or RRC message.
[0547] Exemplarily, the network device reports the prediction result based on an event trigger. For example, when it is predicted that RLF will occur, the prediction result is reported. For details of the specific event, see Example 12.
[0548] In Example 8 and Example 1, the prediction result can be reported to the network via PHY, MAC or RRC message.
[0549] Exemplarily, the prediction result may be sent to the network via a measurement report, for example, carried in the measurement report.
[0550] Exemplarily, the prediction result may be sent to the network via UE assistance information.
[0551] For example, the prediction result may be reported to the network by being carried in SON / MDT and other related information.
[0552] Example 9: If DC is configured, if the UE predicts RLF of the PCell, the above prediction information can be reported through the PSCell. If the UE predicts RLF of the PSCell, the above prediction information can be reported through the PCell.
[0553] For example, it can be reported to the network by being carried in MCG Failure information or SCG Failure information.
[0554] Example 10: Based on Example 1, the UE performs (or initiates) one-time or periodic prediction of wireless link failure and / or corresponding reporting based on the configuration (or indication information) on the network side, and / or protocol agreement and / or UE implementation.
[0555] Embodiment 11: Based on embodiment 10, the network side configuration may include one or more of the following information for initiating radio link failure prediction:
[0556] The duration of the radio link RLF needs to be predicted, or the time window or time range. If the network does not configure the duration to be predicted, the longest possible duration can be predicted based on the performance of the prediction model, or based on the UE implementation or protocol agreement.
[0557] Judgment criteria for RLF prediction: see the first threshold / second threshold in Example 6;
[0558] The network side may also configure a prediction start condition, for example, a threshold value of 1 for the serving cell. When the measurement result of the serving cell is less than the threshold value 1, the prediction is started, such as Nxx in Example 14.
[0559] The network side may also configure the start time of periodic radio link failure prediction (eg, UTC time, SFN, slot, etc.), the prediction duration, and the interval between each prediction.
[0560] Embodiment 12: Based on embodiment 10, the network side configuration may include one or more of the following information for reporting the radio link failure prediction result:
[0561] The network can configure the reporting period;
[0562] The network can also configure reporting events, for example, instructing the UE to start reporting when RLF is predicted; for example, configuring a threshold value of 2 to indicate that the prediction reporting is started when the measurement result of the serving cell is less than the threshold value of 2; for example, a third threshold to indicate that the prediction reporting is started when RLF is predicted and the predicted probability or confidence value of link failure is greater than the third threshold (different from the first and second thresholds).
[0563] Example 13: Based on Example 10, the indication information of the network may be a prediction (and / or) corresponding report of failure to activate or deactivate a radio link.
[0564] The indication information may be one or more of physical layer, MAC layer or RRC layer signaling, for example, activating or deactivating the prediction of radio link failure through MAC CE.
[0565] The indication information may be one or more of physical layer, MAC layer or RRC layer signaling, for example, activating or deactivating reporting of radio link failure through MAC CE.
[0566] Example 14: Based on Example 10, the UE may also start prediction based on protocol agreement, for example:
[0567] When the T310 timer starts running, the UE predicts whether a radio link failure has occurred;
[0568] When receiving the first out-of-synchronization indication from the lower layer, the UE predicts whether a radio link failure has occurred;
[0569] When receiving Nxx out-of-sync indications from the lower layer, the UE predicts whether a radio link failure occurs, where Nxx is configured by the network.
[0570] Embodiment 15, based on embodiment 1, in response to the UE triggering prediction result reporting (or the UE initiating RLF prediction), one or more of the following are performed:
[0571] In response to the UE triggering the prediction result reporting, the UE stops the periodic prediction;
[0572] In response to the UE triggering prediction result reporting (or the UE starting RLF prediction), T310 is stopped.
[0573] Example 16: Based on any one of Examples 1-15, UE capability 1 is introduced, and the UE capability 1 is used to indicate that the UE can perform wireless link failure prediction. The UE can report capability 1 to indicate that the UE supports wireless link failure prediction, and the network side can configure relevant configurations for the UE.
[0574] Embodiment 17: Based on any one of Embodiments 1-15, UE capability 2 is introduced, and the UE capability 2 is used to indicate that the UE can perform radio link failure prediction reporting. In 16 and 17, the UE capabilities 1 and 2 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 to indicate that the UE supports radio link failure prediction reporting, the network side may configure relevant configurations for the UE.
