Description

Wireless communication methods and devices, chips, storage media, and software products Technical Field

[0001] This application relates to the field of mobile communication technology, specifically to a wireless communication method and device, chip, storage medium, and program product. Background Technology

[0002] In cell selection or cell reselection mechanisms, the terminal device needs to continuously perform measurements on the searched cells, or serving cells and neighboring cells. Based on the measurement results, it evaluates the signal quality of the searched cells, or serving cells and neighboring cells. When the cell selection criteria or cell reselection criteria are met, cell selection or cell reselection is performed. Although some conditions are defined to allow the terminal device to refrain from measuring certain frequency points or relax measurement on certain frequency points under certain conditions to achieve UE power saving, measurements in the UE's idle / inactive state are still a source of UE power consumption. Currently, UE measurements still need to be based on their own real-time measurements, but the measurement results of a large number of UEs cannot be well utilized. Summary of the Invention

[0036] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] Communication system scenarios include Terrestrial Networks (TN) and NTN. NTN typically uses satellite communication to provide communication services to terrestrial users. Current NTN systems include NR-NTN and IoT-NTN systems, and other NTN systems may be included in the future.

[0038] Figure 1 is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0039] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0040] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0041] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0042] Terminal device 110 can be used for device-to-device (D2D) communication.

[0043] The wireless communication system 100 may further include a core network device 130 that communicates with a base station. This core network device 130 may be a 5G core network (5G Core, 5GC) device. Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network. During network evolution, the aforementioned core network device may be called by other names, or new network entities may be formed by dividing the functions of the core network; this embodiment does not impose any limitations on this.

[0044] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

[0045] Figure 1 exemplarily illustrates a base station, a core network device, and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices, and each base station may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0046] NTN typically uses satellite communication to provide communication services to terrestrial users. Compared to terrestrial cellular communication, satellite communication has many unique advantages. First, satellite communication is not limited by the user's geographical location. For example, conventional terrestrial communication cannot cover areas such as oceans, mountains, and deserts where communication equipment cannot be installed, or areas with sparse populations where communication coverage is not available. However, with satellite communication, a single satellite can cover a large area, and since satellites orbit the Earth, theoretically every corner of the Earth can be covered by satellite communication. Second, satellite communication has significant social value. Satellite communication can provide coverage in remote mountainous areas and impoverished countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile internet technologies, helping to narrow the digital divide with developed regions and promoting development in these areas. Third, satellite communication has a long range, and the cost does not increase significantly with increasing communication distance. Finally, satellite communication is highly stable and is not affected by natural disasters.

[0047] NTN technology can be combined with various communication systems. For example, NTN technology can be combined with NR systems to form an NR-NTN system. As another example, NTN technology can be combined with Internet of Things (IoT) systems to form an IoT-NTN system. As further examples, an IoT-NTN system can include NB-IoT-NTN systems and eMTC-NTN systems.

[0048] Figure 2 is a schematic diagram of the architecture of another communication system provided in an embodiment of this application.

[0049] As shown in Figure 2, the system includes a terminal device 201 and a satellite 202, which can communicate wirelessly. The network formed between the terminal device 201 and the satellite 202 can also be called an NTN. In the architecture of the communication system shown in Figure 2, the satellite 202 can function as a base station, and the terminal device 201 and the satellite 202 can communicate directly. In this system architecture, the satellite 202 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple network devices 202, and the coverage area of ​​each network device 202 may include other numbers of terminal devices; this application does not limit this aspect.

[0051] As shown in Figure 3, the system includes a terminal device 201, a satellite 202, and a base station 203. Wireless communication is possible between the terminal device 201 and the satellite 202, and communication is possible between the satellite 202 and the base station 203. The network formed by the terminal device 201, satellite 202, and base station 203 can also be called an NTN. In the architecture of the communication system shown in Figure 3, the satellite 202 may not have the function of a base station; communication between the terminal device 201 and the base station 203 requires relaying through the satellite 202. In this system architecture, the base station 203 can be referred to as a network device. In some embodiments of this application, the communication system may include multiple network devices 203, and the coverage area of ​​each network device 203 may include other numbers of terminal devices; this application does not limit this. The network device 203 may be the network device 120 in Figure 1.

[0052] It should be understood that the aforementioned satellite 202 includes, but is not limited to:

[0053] Satellites are categorized into Low-Earth Orbit (LEO), Medium-Earth Orbit (MEO), Geostationary Earth Orbit (GEO), and Highly Elliptical Orbit (HEO) satellites. Satellites can employ multiple beams to cover the ground; for example, a single satellite can generate dozens or even hundreds of beams to cover the ground. In other words, a single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers, ensuring satellite coverage and increasing the overall system capacity of the satellite communication system.

[0054] To ensure satellite coverage and improve the overall capacity of the satellite communication system, satellites use multi-beam coverage to cover the ground. A single satellite can generate dozens or even hundreds of beams to cover the ground; a single satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.

It should also be understood that in the embodiments of this application, the "protocol" can refer to standard protocols in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems, and this application does not limit this.

[0056] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0057] Community Selection

[0058] When a UE selects a new Public Land Mobile Network (PLMN) or Standalone Non-Public Network (SNPN), it performs a cell selection process. If the UE has not stored previous frequency information, it triggers an initial cell selection process. During the initial cell selection process, the UE scans all radio frequency (RF) channels in the New Radio (NR) band to find a suitable cell. At each frequency, the UE searches only the strongest cell, and once a suitable cell is found, the UE selects it. If the UE has stored frequency information and cell parameters, it directly selects a suitable cell once it finds it. If no suitable cell is selected, the UE triggers the initial cell selection process.

[0059] The cell selection S criterion satisfies the conditions: Srxlev > 0 and Squal > 0, where Srxlev is the S value related to the Reference Signal Receiving Power (RSRP) and Squal is the S value related to the Reference Signal Receiving Quality (RSRQ). Where Srxlev = Q rxlevmeas –(Q rxlevmin +Q rxlevminoffset )–P compensation -Q offsettemp Squal = Q qualmeas ? (Q) qualmin +Q qualminoffset )-Q offsettemp ;

[0060] Q rxlevmeas For RSRP measurement;

[0061] Q rxlevmin The minimum RSRP receive strength requirement for the cell is announced via system broadcast;

[0062] Q rxlevminoffset For Q rxlevmin The offset, which is the offset value to prevent the ping-pong effect caused by radio environment fluctuations between two PLMNs, only needs to be considered when normally camped in a suitable cell of the roaming network (VPLMN) and periodically searching for higher priority PLMNs, and is notified in the system broadcast.

[0063] P compensation The system broadcasts a notification to compensate for power loss caused by low power in electronic devices.

[0064] Q offsettemp This is a temporary offset value, announced via system broadcast;

[0065] Q qualmeas For RSRP measurement;

[0066] Q qualmin The minimum RSRQ requirement for the cell is announced via system broadcast.

[0067] Q qualminoffset For Q qualmin The offset, to prevent the ping-pong effect caused by radio environment fluctuations between two PLMNs, only needs to be considered when normally camped in a suitable cell of the roaming network (VPLMN) and periodically searching for a higher priority PLMN, and is notified in the system broadcast.

[0068] Understandably, for UEs in RRC_IDLE and RRC_INACTIVE states, the prerequisite for being able to camp on a certain cell is that the signal quality of that cell (the measurement results of RSRP and RSRQ) meets the cell selection S criterion. After the UE selects a suitable cell, it will continue to evaluate cell reselection.

[0069] Community re-election

[0070] Cell reselection refers to the process by which a UE, in idle mode, monitors the signal quality of neighboring cells and the current cell to select the best cell to provide service signals. During neighboring cell measurement, if the signal quality and level of a neighboring cell meet the S criterion and a certain reselection decision criterion (R criterion), the UE will abandon the current cell and camp on that neighboring cell. When the signal quality and level of a neighboring cell meet the S criterion and a certain reselection decision criterion (R criterion), the terminal will access and camp on that cell.

[0071] After a UE successfully camps, it will continue to perform measurements in the current cell. The RRC layer calculates Srxlev based on the RSRP measurement results and compares it with the intra-frequency measurement initiation threshold (Sintrasearch) and the inter-frequency / inter-system measurement initiation threshold (Snonintrasearch) as the decision criteria for whether to initiate neighbor cell measurements.

[0072] Frequency Priority: To achieve load balancing across different frequency points, the network side can set different priorities for each frequency. UEs preferentially camp on higher-priority frequencies. Frequency priority can be obtained from system broadcasts, dedicated signaling (RRCRelease), or inherited from other RATs.

[0073] The absolute priority of frequencies between different NR frequencies or radio access technologies (RATs) is sent to the UE via system information or an RRC release message, or inherited from another RAT during inter-RAT cell reselection. When the UE is camped on any cell, it should only apply the priority provided by the current cell via system information, and the UE preserves the priority information provided by dedicated signaling or the depriority request indicator (depriorityReq) received in RRCRelease. When the UE is in normal camping mode and only has dedicated frequency priorities other than the current frequency, the UE should treat the current frequency as the lowest priority. When the UE receives an RRCRelease message containing a depriorityReq, the UE should treat the current frequency and stored frequencies or all NR frequencies as the lowest priority frequencies and start or restart a timer T325. Only after T325 times out will the priority of the corresponding frequency or RAT be restored.

[0074] When a UE enters a different RRC state, or its dedicated priority timer (T320) expires, or the RRC Release message received by the UE does not contain cellReselectionPriorities or a NAS request to perform PLMN or SNPN selection, the UE should delete the priority provided via dedicated signaling. The UE cannot consider cells in the exclude-listed list as candidate cells for cell reselection. The UE should only consider cells in the allow-listed list as candidate cells for cell reselection.

[0075] Measurement criteria for cell reselection

[0076] If the serving cell satisfies Srxlev > co-frequency measurement RSRP threshold (S IntraSearchP And Squal > same-frequency measurement RSRQ threshold (S IntraSearchQIf the UE supports location-based measurements and System Information Block 19 (SIB19) broadcasts a distance threshold and reference location, in addition to the above conditions, the following conditions must also be met: If the distance between the UE and the serving cell reference point is less than distanceThresh, the UE may not perform intra-frequency cell measurements; otherwise, the UE must perform intra-frequency measurements. For NTN earth-moving cells, if the UE supports location-based measurements and SIB19 broadcasts distanceThresh and moving reference location, in addition to the above conditions, the following conditions must also be met: If the distance between the UE and the serving cell reference point is less than distanceThresh, the UE may not perform intra-frequency cell measurements; otherwise, the UE must perform intra-frequency measurements.

[0077] For high-priority frequencies, the UE needs to perform inter-frequency or inter-RAT frequency measurements. For frequencies of the same or lower priority, when the serving cell satisfies Srxlev > inter-frequency measurement RSRP threshold (S nonIntraSearchP And Squal > inter-frequency measurement RSRQ threshold (S nonIntraSearchQ When the UE supports location-based measurements and SIB19 broadcasts distanceThresh and referenceLocation, in addition to the above conditions, the UE may not perform measurements on cells with the same or lower priority frequencies if the distance between the UE and the serving cell reference point is less than distanceThresh. Otherwise, the UE needs to perform measurements on cells with the same or lower priority frequencies. For NTN earth-fixed cells, if the UE supports location-based measurements and SIB19 broadcasts distanceThresh and movingReferenceLocation, in addition to the above conditions, the UE may not perform measurements on cells with the same or lower priority frequencies if the distance between the UE and the serving cell reference point is less than distanceThresh. Otherwise, the UE needs to perform measurements on cells with the same or lower priority frequencies. For NTN earth-moving cells, if the UE supports location-based measurements and SIB19 broadcasts distanceThresh and movingReferenceLocation, in addition to the above conditions, the UE may not perform measurements on cells with the same or lower priority frequencies if the distance between the UE and the serving cell reference point is less than distanceThresh. Otherwise, the UE needs to perform measurements on cells with the same or lower priority frequencies.

[0078] If relaxed measurement is configured in SIB2 and the UE supports measurement relaxation, the UE can perform measurement relaxation.

[0079] For UEs camped in NTN cells, if skipping terrestrial network TN measurements is supported, and the UE has already obtained location information and broadcast coverageAreaInfoList and tn-AreaIdList in the system message, the UE may not perform TN frequency measurements when it is not covered by the frequencies provided by tn-AreaIdList.

[0080] When the UE supports time-based measurements and the service time (t-service) is broadcast in SIB19, the UE needs to perform in-frequency or inter-RAT measurements before t-service, regardless of the distance between the UE and the serving cell reference point or whether the serving cell satisfies Srxlev > S. IntraSearchP And Squal > S IntraSearchQ , or Srxlev>S nonIntraSearchP And Squal > S nonIntraSearchQ The UE needs to perform measurements on high-priority frequencies regardless of how much service time remains in the serving cell.

[0081] NR inter-frequency and inter-RAT cell reselection criteria

[0082] If the system broadcasts a service threshold (threshServingLowQ) and the UE camps on the current serving cell for more than 1 second, the UE will select a higher priority cell if the following conditions are met: the higher priority cell has been selected for a certain period of time. RAT The inner condition satisfies Squal > Thresh X,HighQ Otherwise, the UE selects a high-priority cell if the following conditions are met: the high-priority cell has been selected for a certain period of time (Treselection). RAT The inner condition satisfies Srxlev > Thresh X,HighP Furthermore, the UE has been camped in the current serving cell for more than 1 second.

[0083] When multiple cells meet the above criteria, the UE should reselect a cell according to the following:

[0084] - If the highest priority frequency is the NR frequency, the best ranked cell on that frequency must meet the cell reselection criteria of the same frequency.

[0085] - If the highest priority frequency is from another RAT, the best ranked cell on that frequency meets the criteria of that RAT.

[0086] Cell reselection criteria for cells with the same priority or lower priority frequencies:

[0087] The cell ranking criteria for serving cell Rs and neighboring cells Rn, namely the R criterion, are defined as follows: R s =Q meas,s +Q hyst -Qoffset temp R n =Q meas,n -Qoffset-Qoffset temp ;

[0088] Among them, Q meas,s RSRP measurements for the service cell reselection; Q hyst Qoffset is the cell reselection hysteresis value, used to adjust the difficulty of reselection, reduce the ping-pong effect, and is announced in the system broadcast; temp This is a temporary offset value, announced via system broadcast; Q meas,n RSPR measurement of neighboring cells for cell reselection; Qoffset, for co-frequency measurements, is Qoffset. s，n For inter-frequency measurements, it is Qoffset. s，n +Qoffset frequency Qoffset frequency This is a frequency-related offset value.

[0089] The UE should rank all cells that meet the S criterion according to the R criterion described above. If the optimal cell range (rangeToBestCell) is not configured, the UE performs cell reselection to the highest-ranked cell. If this cell is unsuitable, the UE will not consider any cells on that frequency for 300 seconds. If rangeToBestCell is configured, the UE should perform cell reselection to the cell with the most beams exceeding the threshold. If multiple such cells exist, the UE will reselect the highest-ranked cell.

[0090] In all the above scenarios, the following must be satisfied: the new cell must meet the reselection criteria for a certain period of time (Treselection). RAT And the UE has been camped in the current cell for more than 1 second.

[0091] Current research has demonstrated the powerful predictive capabilities of AI. Therefore, combining AI with communication technologies is expected to better serve communication systems. Current research and evaluation have shown that the combination of AI and communication technologies can bring about significant performance improvements.

[0092] In current cell selection and reselection mechanisms, the UE needs to continuously perform measurements on the serving cell and neighboring cells. Based on the measurement results, the signal quality of the serving cell and neighboring cells is evaluated. Cell selection and reselection are then performed when the cell selection and reselection criteria are met. Although some conditions are defined to allow the UE to avoid measuring certain frequencies or relax measurement on certain frequencies to save power, measurements in the idle / inactive state remain the main source of UE power consumption. Currently, UE measurements still rely on their own real-time measurements, but a large number of UE measurement results are not effectively utilized.

[0093] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments.

[0123] If the first indication information indicates that the currently accessed cell does not support AI cell selection or cell reselection, the terminal device will not perform cell selection and / or cell reselection based on the first model. The terminal device may perform cell selection based on the first criterion or cell reselection based on the second criterion.

[0124] The second indication information is used to indicate whether the neighboring cell supports AI-based cell selection and / or cell reselection.

[0125] When a neighboring cell supports AI-based cell selection and / or cell reselection, the terminal device inputs a second indication information indicating that the neighboring cell supports AI-based cell selection and / or cell reselection into the first model. The first model can prioritize the neighboring cell as the target cell based on the second indication information and include the target cell in the output parameters.

[0126] In this embodiment, if the first model is used for cell selection, the second indication information is not required. If the first model is used for both cell selection and cell reselection (i.e., cell selection and cell reselection use the same AI model), and the network device is unaware of whether the terminal device is performing cell selection, the second indication information may or may not be present. If the second indication information is present and the terminal device performs cell selection based on the first model, the terminal device may disregard the second indication information.

[0127] The third indication information is used to instruct the terminal device whether to perform AI-based cell selection and / or cell reselection.

[0128] When instructed by the third instruction information to perform AI-based cell selection and / or cell reselection, the terminal device may perform cell selection and / or cell reselection based on the first model.

[0129] The model information refers to information related to the first model.

[0130] In this embodiment of the application, when the terminal device performs cell selection or cell reselection based on the first model, it may perform cell selection or cell reselection based on some or all of the information in the first information.

[0131] In some embodiments, the model information includes one or more of the following:

[0132] First model information, which is used to obtain the first model;

[0133] Second model information, which is used to indicate the effective area of ​​the first model;

[0134] For a first time period, the measurement result input to the first model is the measurement result within the most recent first time period;

[0135] The second duration is the duration of waiting for the output parameters of the first model;

[0136] The third duration is the input period of the input parameters of the first model;

[0137] The first count is the maximum number of times the input parameters of the first model are input;

[0138] The second count is the maximum number of times the output parameters of the first model do not meet the requirements.

[0139] Third model information, which is used to indicate the input parameters of the first model;

[0140] The fourth model information is used to indicate the output parameters of the first model.

[0141] Regarding the first model information, if the model information includes the first model information, the terminal device can obtain the first model based on the first model information.

[0142] In some embodiments, the first model information includes one or more of the following:

[0143] The index of the first model;

[0144] The first model includes data or containers;

[0145] First address information, which is used to obtain the first model.

[0146] For the index of the first model, the terminal device can select the model corresponding to the index of the first model from multiple models as the first model, where different models correspond to different indexes.

[0147] For the data and containers included in the first model, the terminal device can generate the first model based on the data or containers included in the first model.

[0148] Based on the first address information, the terminal device can obtain the first model.

[0149] In one example, the first address information is the IP address of the first model.

[0150] Regarding the first model information, if the model information includes the second model information, the terminal device determines whether the current area is a valid area of ​​the first model; if the current area is included in the valid area of ​​the first model, cell selection and / or cell reselection can be performed based on the first model; if the current area is not included in the valid area of ​​the first model, the terminal device cannot perform cell selection and / or cell reselection based on the first model.

[0151] In some embodiments, the effective region includes at least one or more of the following:

[0152] One or more PLMNs;

[0153] One or more SNPNs;

[0154] One or more tracking areas (TAs);

[0155] One or more residential communities;

[0156] One or more Radio Access Network (RAN) Notification Areas (RNAs).

[0157] The granularity of the effective region may include at least one of the following: PLMN, SNPN, TA, microcell, RNA.

[0158] One or more PLMNs can be described as PMLNs or a list of PMLNs.

[0159] One or more SNPNs can be described as SNPNs or a list of SNPNs.

[0160] One or more TAs can be described as TAs or a list of TAs.

[0161] One or more cells can be described as cells or a list of cells.

[0162] One or more RNAs can be described as RNAs or a list of RNAs.

[0163] For the first duration, the maximum duration of the measurement results input to the first model; wherein, the terminal device provides the measurement results within the most recent first duration to the first model. The first duration can be identified as T1.

[0164] For a measurement result, if the duration of the measurement result is less than or equal to a first duration, the measurement result is determined to be a valid measurement result and can be input into the first model; if the duration of the measurement result is greater than the first duration, the measurement result is determined to be an invalid measurement result and will not be input into the first model.

[0165] The duration of the measurement result can be understood as the time interval between the time it takes to input the measurement result into the first model and the measurement time of that measurement result.

[0166] The second duration is the waiting time for the output parameters of the first model. The second duration can be denoted as T2.

[0167] After inputting the input parameters into the first model, a timer can be started. The timer duration is the second duration, during which the device waits for the output parameters of the first model. If the terminal device does not receive the output parameters of the first model when the timer expires, it will no longer wait for the output parameters of the first model and can either input the input parameters into the first model again or revert to the cell selection process based on the first criterion or the cell reselection process based on the second criterion.

[0168] The third duration is the input period for the terminal device to input parameters to the first model. The third duration can be identified as T3.

[0169] The terminal device can input parameters to the first model once every three time intervals.

[0170] The first number represents the maximum number of times the terminal device can repeatedly input the information. The first number can be denoted as N1.

[0171] After the terminal device inputs an input parameter, it increments the value of the number of times the input parameter is repeated, N, by 1, and waits for the output parameter from the first model. If the output parameter from the first model is not obtained, the terminal device can check the number of times the input parameter has been repeated, N. If N is less than N1, the terminal device can repeatedly input the input parameter and increment the value of N by 1. If the value of N is equal to 1, the input parameter is no longer input to the first model.

[0172] The second number represents the maximum number of times the output parameters of the first model fail to meet the requirements. This second number can be denoted as N².

[0173] The failure of the output parameters of the first model to meet the requirements can be understood as the failure of the residential cells determined based on the output parameters of the first model to meet the requirements. The first rule used to determine whether the output parameters of the first model meet the requirements includes, but is not limited to, one or more of the following:

[0174] The output parameters of the first model include the measurement results of the target cell, which do not meet the S criterion;

[0175] The output parameters of the first model include whether the target cell meets the R criterion, etc.

[0176] In this embodiment of the application, the first rule can be set according to actual needs.

[0177] If the number of times the output parameters of the first model fail to meet the requirements reaches the second number, the terminal device can revert to the cell selection process based on the first criterion or the cell reselection process based on the second criterion.

[0178] The third model information indicates the parameters that the first model needs to input. The third model information can be described as a list of input parameters.

[0179] The terminal device can input the corresponding input parameters into the first model according to the input parameters indicated by the third model information.

[0180] In some embodiments, the input parameters of the first model include one or more of the following:

[0181] Service area signage;

[0182] The fourth indication information is used to indicate whether to perform cell selection or cell reselection;

[0183] Cell measurement results for one or more cells;

[0184] The fifth indication information is used to indicate whether the input parameters include beam-based measurement results;

[0185] Beam measurement results and beam indication information for each cell in the one or more cells;

[0186] One or more features supported by the terminal device;

[0187] The priority of each feature among one or more features supported by the terminal device;

[0188] Frequency priority of each frequency in one or more frequencies;

[0189] Mobility information of terminal devices;

[0190] Location information of the terminal device;

[0191] Configuration information of each cell in the one or more cells.

[0192] The serving cell identifier is used to identify the cell that the terminal device is currently accessing.

[0193] The fourth indication information is used to indicate whether cell selection or cell reselection is currently performed based on the first model.

[0194] Cell measurement results for one or more cells are the measurement results obtained by measuring each cell in one or more cells. Cell measurement results include the signal quality of the cell, which includes one or more of the following: RSRP measurement results and / or RSRQ measurement results.

[0195] When performing cell selection, the input parameters of the first model may include cell measurement results of one or more cells.

[0196] When performing cell reselection, the input parameters of the first model may include cell measurement results of multiple cells, where the multiple cells include the serving cell and one or more neighboring cells.

[0197] The fifth indication information is used to indicate whether to input beam-based measurement results into the first model.

[0198] The beam measurement results for one or more cells refer to the measurement results obtained by measuring the beams of each cell in the one or more cells. The beam measurement includes the signal quality of the beams.

[0199] The terminal device may support one or more of the following features: slicing, small data transmission, and energy saving.

[0200] When the input parameters include one or more features supported by the terminal device, the target cell output by the first model can be a cell that supports features including those supported by the terminal device.

[0201] In one example, if the terminal device supports feature 1, then the target cell output by the first model can be a cell that supports feature 1.

[0202] For the priority of each feature among one or more features supported by the terminal device, the target cell output by the first model can be a cell that supports features including those with higher priority among the features supported by the terminal device.

[0203] In one example, the terminal device supports feature 1 and feature 2, and feature 1 has a higher priority than feature 2. In this case, the target cell output by the first model can be the cell that supports the higher-priority feature 1.

[0204] In this embodiment of the application, the priority of features can be configured by the Non-Access Layer (NAS) layer.

[0205] Given the frequency priority of one or more frequencies, the target cell output by the first model can be the cell at the frequency with the higher frequency priority.

[0206] Optionally, the frequency priority of each of the one or more frequencies is the frequency priority of the one or more frequencies received by the terminal device via dedicated signaling.

[0207] Mobility information for terminal devices can characterize the mobile status of the terminal devices.

[0208] In one example, the mobility state of the terminal device may include: high-speed mobility state, medium-speed mobility state, and low-speed mobility state. The mobility information of the terminal device is used to indicate whether the terminal device is in a high-speed mobility state, medium-speed mobility state, or low-speed mobility state.

[0209] The mobility status of the terminal device can be assessed by the terminal device itself.

[0210] The location information for the terminal device can be either GNSS location or coarse location information.

[0211] The location information of the terminal device can be used by the first model to perform AI-based cell selection and / or cell reselection based on the location information.

[0212] For the configuration information of each cell in one or more cells, the cell configuration information is used to indicate one or more of the following: supported features, SSB period, supported adjacent frequencies, and frequency priority of each adjacent frequency.

[0213] The fourth model information indicates the parameters that the first model can output. The fourth model information can be described as a list of output parameters.

[0214] The first model can output corresponding parameters according to the instructions of the fourth model, so that the terminal device can obtain the output parameters of the first model.

[0215] The terminal device determines the cell to camp on based on the output parameters of the first model and camps on the cell.

[0216] In some embodiments, the output parameters of the first model include one or more of the following:

[0217] The sixth indication information is used to indicate whether to perform cell selection;

[0218] The seventh indication information is used to indicate whether to perform cell reselection;

[0219] The eighth indication information is used to indicate the type of cell reselection to be performed;

[0220] The ninth indication information is used to indicate whether to enter the first state, where the first state is the state of being stationed in any cell;

[0221] The second information is used to perform cell selection or cell reselection.

[0222] The validity period of the second information.

[0223] The sixth instruction information indicates whether or not to perform cell selection.

[0224] When the sixth instruction information indicates that cell selection should be performed, the terminal device performs cell selection based on the second information output by the first model.

[0225] The seventh instruction message indicates whether or not to perform a cell reselection.

[0226] When the seventh instruction information indicates that cell reselection should be performed, the terminal device performs cell reselection based on the second information output by the first model.

[0227] Understandably, if the output parameters of the first model include the sixth and seventh indication information, the indication results of the sixth and seventh indication information include one of the following:

[0228] The sixth instruction indicates that cell selection should be performed, and the seventh instruction indicates that cell reselection should not be performed;

[0229] The sixth instruction indicates that cell selection should not be performed, and the seventh instruction indicates that cell reselection should be performed;

[0230] The sixth instruction indicates that cell selection should not be performed, and the seventh instruction indicates that cell reselection should not be performed.

[0231] The eighth instruction indicates which type of cell reselection to perform.

[0232] In this embodiment of the application, the cell reselection types include: intra-frequency cell reselection, inter-frequency cell reselection, and cross-RAT cell reselection.

[0233] Understandably, the eighth indication information indicates different cell reselection types based on different values. If the value of the eighth indication information is a predetermined value, no cell reselection type may be indicated.

[0234] If the output parameters of the first model do not include the seventh indication information or include the seventh indication information indicating that cell reselection should not be performed, the eighth indication information does not indicate any cell reselection type.

[0235] In this embodiment of the application, when the output parameters of the first model include the eighth indication information and the eighth indication information indicates a specific cell reselection type, the terminal device determines whether to perform cell reselection based on the eighth indication information. In this case, the output parameters of the first model may not include the seventh indication information.

[0236] The ninth indication message indicates whether to enter the first state. The first state can be referred to as the "camped on any cell" state.

[0237] When the ninth instruction indicates that the terminal device should enter the first state, the terminal device enters the first state.

[0238] The second piece of information is used to determine the cell where the terminal device camps for cell access or cell reselection, i.e., the camping cell, and can also be used to determine the beam used when the terminal device camps on the camping cell.

[0239] In some embodiments, the second information includes one or more of the following:

[0240] One or more frequencies used for residence;

[0241] One or more target cells;

[0242] The priority of the target cell;

[0243] One or more target beams;

[0244] The priority of the target beam.

[0245] For one or more frequencies used for camping, the terminal device camps on a cell on one of the one or more camping frequencies.

[0246] For one or more target cells, the terminal device may reside in one of the target cells.

[0247] If the second piece of information includes the priority of the target cell, the terminal device can camp on the target cell with the higher priority.

[0248] If the second information includes one or more target beams, the terminal device may use one or more target beams to camp on the camping cell.

[0249] If the second information includes the priority of the target beam, the terminal device may use one or more target beams with higher priority to camp in the camping cell.

[0250] In this embodiment of the application, the input parameters of the first model may also include a first time, which can be understood as service time (t-service).

[0251] In some embodiments, S401 in FIG4 includes:

[0252] The terminal device receives a first message, which includes the first information; the first message includes one or more of the following messages: a system broadcast message; or the terminal device's dedicated signaling.

[0253] Accordingly, S501 in Figure 5 includes:

[0254] The network device sends a first message, the first message including the first information; the first message includes one or more of the following messages: system broadcast message; dedicated signaling of the terminal device.

[0255] When the first message is a system broadcast message, the network device broadcasts a system message, and multiple terminal devices under the network device can listen to the broadcast message sent by the network device. In this case, the first information included in the broadcast message applies to multiple terminal devices.

[0256] System messages can be dedicated system messages, i.e. newly defined system messages, or system messages used for cell selection and cell reselection.

[0257] The first information included in the system message may include: first indication information and second indication information.

[0258] System messages may include SIB messages.

[0259] In the case where the first message is a dedicated signaling message for the terminal device, the network device sends the dedicated signaling message for the terminal device to the terminal device, and the terminal device receives the dedicated signaling message for the terminal device sent by the network device.

[0260] In this embodiment of the application, the terminal device may obtain first information through dedicated signaling when entering the connected state or when entering the idle state or inactive state from the connected state.

[0261] In some embodiments, the dedicated signaling of the terminal device includes one or more of the following: RRC Reconfiguration message; RRC Resume message; RRC Release message.

[0262] In one example, the terminal device obtains initial information via an RRCReconfiguration message or an RRCResueme message after entering the connected state.

[0263] In one example, when the terminal device transitions from a connected state to an idle state or an inactive state, the terminal device obtains the first message via the RRCRelease message.

[0264] In one example, when the terminal device performs cell handover in connected mode, it obtains the first information through the RRCReconfiguration message.

[0265] In this embodiment of the application, the first information obtained by the terminal device when it enters the idle state or the active state from the connected state may include: third indication information.

[0271] S901, The terminal device sends third information to the network device, the third information being used to indicate whether the terminal device supports AI-based cell selection and / or cell reselection.

[0272] In the embodiments of this application, the wireless communication methods shown in Figures 4, 5 or 6, and the wireless communication methods shown in Figures 7, 8 and 9 can be implemented separately or in combination.

[0273] The third piece of information can be understood as the capabilities of the terminal device.

[0274] In this embodiment of the application, the network device may send first information to the terminal device if the third information received from the terminal device indicates that the terminal device supports AI-based cell selection and / or cell reselection. As shown in Figure 10, this includes:

[0275] S901, The terminal device sends third information to the network device.

[0276] S401, The network device sends the first information to the terminal device.

[0277] In some embodiments, S701 in FIG7 includes:

[0278] The terminal device sends a second message, the second message including the third information;

[0279] The second message includes one or more of the following messages: capability reporting message and RRC connection completion message.

[0280] Accordingly, S801 in Figure 8 includes:

[0281] The network device receives a second message, the second message including the third information;

[0282] The second message includes one or more of the following messages: capability reporting message and RRC connection completion message.

[0283] RRC connection completion messages may include RRC setup complete (RRCSetupComplete) and RRC recovery complete (RRCResumeComplete) messages.

[0284] In some embodiments, when a terminal device connects to a cell, it reports third information via a second message.

[0285] In one embodiment, based on FIG7, the wireless communication method provided in this application embodiment further includes:

[0286] The terminal device receives a third message, which is used to request the third information.

[0287] Accordingly, based on Figure 8, the wireless communication method provided in this application embodiment further includes:

[0288] The network device sends a third message, which is used to request the third information.

[0289] The third message can be understood as a message requesting the terminal device to report its capabilities.

[0290] The network device sends a third message, and the terminal device receives the third message and, in response, sends third information back to the network device. Understandably, the terminal device includes the third information in the second message based on a network request.

[0291] This application provides a wireless communication method applied to a terminal device, as shown in Figure 11, including:

[0292] S1101. The terminal device inputs the input parameters into the first model and obtains the output parameters of the first model;

[0293] S1102. The terminal device determines the cell to be used based on the output parameters.

[0294] In the embodiments of this application, the wireless communication method shown in FIG11, the wireless communication method shown in FIG4, and the wireless communication method shown in FIG7 can be implemented individually or in combination.

[0295] When the terminal device performs cell selection or cell reselection based on the first model, the terminal device inputs input parameters to the first model and determines the cell to camp on based on the output parameters of the first model. The terminal device can periodically input input parameters to the first model, or it can input input parameters to the first model based on the trigger of obtaining measurement results.

[0296] Optionally, after the terminal device obtains the first model, if the first information includes the second model information and the area where the terminal device is located is within the effective area of ​​the first model, the terminal device can use the first model to perform AI-based cell selection or cell reselection.

[0297] Taking cell selection based on the first model as an example, when the terminal device selects a new PLMN or SNPN, and has stored first information and previous frequency point information, the terminal device uses the first model to perform AI-based cell selection. The terminal device inputs fourth indication information to the first model to perform cell selection, and inputs the measurement results of the most recent first time period from the stored frequency point list into the first model, and waits for the output parameters of the first model.

[0298] Taking cell reselection based on the first model as an example, the terminal device, upon receiving measurement results or periodically inputting parameters such as the serving cell identifier and measurement results of the serving cell and neighboring cells within the most recent first time interval into the first model, waits for the output parameters of the first model. If the first information indicates that the input parameters include the beam measurement results of each cell, the input parameters input by the terminal device into the first model also include the beam measurement results of the serving cell and neighboring cells, and the beam index.

[0299] If the first information includes a second duration, the terminal device will input the first model, start a timer with a duration of the second duration, and wait for the output parameters of the first model. The second duration can be the same or different for cell selection and cell reselection. If the timer expires and the first model has not output any parameters, the terminal device will re-input the parameters to the first model and restart the timer.

[0300] In this embodiment, if the terminal device inputs input parameters to the first model and the first model does not output any output parameters, the terminal device can input the input parameters again, or revert to cell selection based on the first criterion or cell reselection based on the second criterion.

[0301] In this embodiment of the application, if the terminal device fails to determine the cell to camp on based on the output parameters of the first model, it can perform measurements based on other frequency points to obtain new measurement results, and input the input parameters including the measurement results into the first model to obtain new output parameters; or it can revert to cell selection based on the first criterion or cell reselection based on the second criterion.

[0302] In some embodiments, S1102, the terminal device determines the cell to be used based on the output parameters, including:

[0303] When the output parameters include a sixth indication indicating cell selection, a seventh indication indicating cell reselection, or a ninth indication indicating entry into a first state, the terminal device determines the cell to be camped on based on one or more target cells included in the output parameters.

[0304] The output parameters of the first model include one or more target cells, which can be understood as cells recommended by the first model. The terminal device can determine a cell from the cells recommended by the first model as the camping cell, and the terminal device camps on the camping cell.

[0305] In this embodiment of the application, the terminal device can directly perform cell selection and cell reselection based on the target cell output by the first model, or it can select or reselect to the corresponding cell based on the measurement results of the target cell output by the first model.

[0306] Taking the terminal device directly performing cell selection and cell reselection based on the target cell output by the first model as an example

[0307] In some embodiments, the terminal device in S1102 determines the cell to be used based on the output parameters, including one of the following:

[0308] If the output parameters include a target cell, the terminal device determines the target cell as the cell to be camped on.

[0309] When the output parameters include multiple target cells and the priority of the target cells, the terminal device determines the target cell with the highest priority as the camping cell, or determines the target cell with the highest signal quality among the multiple target cells as the camping cell.

[0310] If the first model outputs a target cell, the terminal device can directly select that target cell to perform camping or reselect to camp on that target cell.

[0311] If the first model outputs multiple target cells and the priority of each target cell, the terminal device can select the higher priority target cell to camp on or reselect to camp on the higher priority target cell.

[0312] If the first model outputs multiple target cells, the terminal device can select the target cell with the highest signal quality to camp on or reselect to camp on the target cell with the highest signal quality based on the measurement results of each target cell.

[0313] Taking the terminal device selecting or reselecting the corresponding cell based on the measurement results of the target cell output by the first model as an example

[0314] In some embodiments, S1102, the terminal device determines the cell to be used based on the output parameters, including:

[0315] When the output parameters include one or more target cells, the terminal device measures the one or more target cells to obtain the measurement results of the multiple target cells;

[0316] The terminal device selects a cell based on the measurement results of the one or more target cells and a first criterion, or performs cell reselection based on the measurement results of the one or more target cells and a second criterion, to determine the cell to be used.

[0317] The first model outputs one or more target cells. The terminal device then measures one or more recommended target cells again. Based on the measurement results of one or more target cells, it uses a first criterion to decide whether to perform cell selection and the selected camping cell, or uses a second criterion to decide whether to perform cell reselection and the reselected camping cell.

[0318] Here, one or more target cells output by the first model are provided as references, and the UE needs to perform further verification of the target cells output by the first model. When the first model outputs a target cell, the terminal device performs a measurement on the target cell. If the measurement result of the target cell is higher than a threshold configured by the network (different thresholds may be configured for co-frequency cells, high-priority cells, and low or co-priority cells), the terminal device selects or reselects the target cell as the cell to be camped.

[0319] The terminal device can input the indication information that the target cell recommended by the first model does not meet the requirements into the first model, and re-input the input parameters into the first model, and wait for the output of the first model.

[0320] If the first information includes the second count, and the number of times the target cell recommended by the first model does not meet the requirements reaches the second count, the terminal device can exit the AI-based cell selection or cell reselection.

[0321] In some embodiments, based on FIG11, the wireless communication method provided in this application further includes:

[0322] When the output parameters include a target beam, the terminal device camps on the camping cell based on the target beam;

[0323] When the output parameters include multiple target beams and the priority of the target beams, the terminal device camps on the camping cell based on the target beam with the highest priority.

[0324] When the output of the first model includes one or more target beams and the camping cell is the target cell recommended by the first model, when the terminal device camps on the target cell, it camps on the camping cell based on one of the one or more target beams.

[0325] If the first model outputs a target beam, the terminal device directly camps on the desired cell based on that target beam.

[0326] If the first model outputs multiple target beams and the priority of each target beam, the terminal device can select the target beam with the higher priority to camp on the cell based on the priority.

[0327] If the first model outputs multiple target beams, the terminal device can select the target beam with the highest signal quality to camp on the cell based on the measurement results of each target beam.

[0328] In some embodiments, if the signal quality of the determined target beam is greater than a second threshold, the terminal device camps on the determined target beam to a designated cell; otherwise, the determined target beam is not considered.

[0329] In some embodiments, if the signal quality of one or more target beams included in the output parameters of the first model is greater than a second threshold, the terminal device determines the target beam to be camped on in the camping cell from the target beams whose signal quality is greater than the second threshold.

[0330] In some embodiments, in the case of cell selection, the method further includes one or more of the following:

[0331] If the sixth indication information included in the output parameters indicates that cell selection should not be performed, the terminal device performs cell selection based on the first criterion.

[0332] If the terminal device inputs the first set of input parameters to the first model but does not obtain the output parameters of the first model, the terminal device selects a cell based on the first criterion.

[0333] If the number of times the number of times the cell to be used does not meet the requirements, determined based on the output parameters of the first model, reaches a second number, the terminal device selects a cell based on the first criterion.

[0334] If the signal quality of the target cell included in the output parameters of the first model is lower than a first threshold, the terminal device selects a cell based on a first criterion.

[0335] If the output parameters of the first model do not include the target cell, the terminal device selects a cell based on the first criterion.

[0336] If the output parameters of the first model are not obtained within the second time period, the terminal device performs cell selection based on the first criterion.

[0337] Understandably, the terminal device selects cells based on the first model. If the output parameters of the first model satisfy the second rule, the terminal device exits the AI-based cell selection and performs cell reselection based on the first criterion. The second rule includes one or more of the following:

[0338] Rule 1: The sixth indication information in the output parameters of the first model indicates that cell selection should not be performed;

[0339] Rule 2: The first model receives the input parameters for the first number but does not receive the output parameters for the first model.

[0340] Rule 3: The number of times the residency cell determined based on the output parameters of the first model fails to meet the requirements reaches the second count;

[0341] Rule 4: The output parameters of the first model include the signal quality of the target cell being lower than the first threshold.

[0342] Rule 5: The output parameters of the first model do not include the target cell;

[0343] Rule 6: The first model does not output any output parameters within the second time period after inputting the input parameters.

[0344] In this embodiment of the application, the first criterion may include the S criterion.

[0345] In this embodiment of the application, the terminal device's cell selection based on the first criterion can be understood as the terminal device reverting to the traditional (legacy) cell selection mechanism.

[0346] In some embodiments, in the case of cell reselection, the method further includes:

[0347] If the seventh indication information included in the output parameters indicates that cell reselection should not be performed, the terminal device performs cell reselection based on the second criterion.

[0348] If the output parameters of the first model are not obtained within the second time period, the terminal device performs cell reselection based on the second criterion.

[0349] If the terminal device inputs the first set of input parameters to the first model but does not obtain the output parameters of the first model, the terminal device performs cell reselection based on the second criterion.

[0350] If the number of times the number of times the selected cell does not meet the requirements, as determined by the output parameters of the first model, reaches a second number, the terminal device performs cell reselection based on the second criterion.

[0351] If the signal quality of the target cell included in the output parameters is lower than the second threshold, the terminal device performs cell reselection based on the second criterion.

[0352] If the output parameters do not include the target cell, the terminal device performs cell reselection based on the second criterion.

[0353] Understandably, the terminal device performs cell reselection based on the first model. If the output parameters of the first model satisfy the third rule, the terminal device exits the AI-based cell reselection and performs cell reselection based on the second criterion. The third rule includes one or more of the following:

[0354] Rules 2 through 7, wherein rule 7 is the seventh indication information included in the output parameters of the first model, indicating that cell reselection should not be performed.

[0355] In this embodiment of the application, the second criterion may include the S criterion and the R criterion.

[0356] In this embodiment of the application, the cell selection based on the second criterion by the terminal device can be understood as a cell reselection mechanism for the terminal device to fall back to legacy.

[0357] In some embodiments, based on FIG11, the wireless communication method provided in this application further includes:

[0358] If the terminal device is denied permission to camp in the designated cell, the terminal device will send a tenth indication message to the first model. The tenth indication message is used to indicate that the terminal device has been denied permission to camp in the designated cell.

[0359] In this embodiment of the application, if the terminal device is rejected when it tries to camp on a cell, the UE will not consider the cell for a fourth time period and will feed back the identifier of the cell and the tenth indication information to the first model.

[0360] The fourth duration can include 200 seconds (s), 300 seconds, etc. The fourth duration can be predefined or configured by the network device.

[0361] The wireless communication method provided in this application will now be described through several embodiments.

[0362] This application provides an AI-based cell selection and reselection scheme: When a UE connects to a cell, it reports whether it supports AI-based cell selection and reselection via a connection completion message (e.g., RRCSetupComplete, RRCResumeComplete). Based on a network request, the UE includes whether it supports AI-based cell selection and reselection in its UE capability information reporting message.

[0363] The base station broadcasts AI-related information in its broadcast messages. This information can be included in a regular SIB message or a separate SIB message containing AI-based cell selection and cell reselection information. Alternatively, the UE can obtain the AI ​​model (i.e., the first model) information used for cell selection and cell reselection from the RRCReconfiguration / RRCResueme or RRCLease messages after entering connected mode. AI-based cell selection and cell reselection information can include one or more of the following:

[0364] Does this cell support AI-based cell selection and cell reselection instructions?

[0365] AI model-related information used for cell selection and / or cell reselection.

[0366] The AI ​​model information used for cell selection and / or cell reselection includes one or more of the following:

[0367] a. Index of AI models;

[0368] b. The data of the AI ​​model or a container

[0369] c. Obtain the address of the AI ​​model; the UE obtains the AI ​​model through this address.

[0373] g. The period T3 of the UE input measurement result;

[0374] h, the maximum number of times the UE can retry N1;

[0375] i. The list of parameters that the AI ​​model requires from the user interface (UE);

[0376] j. The list of parameters output by the AI ​​model.

[0377] The above information i, the list of parameters that the AI ​​model requires UE input, includes one or more of the following parameters:

[0378] i1, the cell ID where the UE is located;

[0379] i2. Instructions for whether to perform cell selection or cell reselection;

[0380] i3. Measurement results from this cell and / or neighboring cells: RSRP measurement and / or RSRQ measurement results;

[0381] i4. Instructions for whether to input beam-based measurement results;

[0382] i5. Beam measurement results and beam indication information for this cell and / or neighboring cells;

[0383] i6, Features supported by UE (such as slicing, small data transmission, UE power saving, etc.);

[0384] i7, the priority of the features supported by the UE, which can be configured by the UE's NAS layer;

[0385] i8, the frequencies received by the UE via dedicated signaling and their corresponding frequency priorities;

[0386] i9. UE mobility information, such as the UE's assessed high-speed mobility state, medium-speed mobility state, or low-speed mobility state.

[0387] The location information of i10 and UE can be Global Navigation Satellite System (GNSS) location or coarse location information;

[0388] i11. Current configuration information of this cell, such as SSB cycle, supported adjacent frequency points, and the priority of each frequency point.

[0389] In this embodiment, the AI ​​model can be trained based on the configuration information of the cell, so that the AI ​​model outputs more accurate output parameters (i.e., recommendation results) based on the configuration information of the cell. When the configuration information of the cell is updated, the terminal device inputs the configuration information of the cell into the AI ​​model to obtain the output parameters of the AI ​​model based on the current configuration information of the cell. Thus, when the configuration information of the cell changes, it is not necessary to re-acquire the AI ​​model.

[0390] The above information j, the list of output parameters of this AI model, includes one or more of the following output parameters:

[0391] j1. Should the cell selection instruction be executed?

[0396] j6. Recommended target cell beam indication;

[0397] j7. Recommended beam priority for the target cell;

[0398] j8. The effective period of the recommended information.

[0399] The UE inputs the configuration information of the current cell, as well as the measurement information of the current cell and neighboring cells, into the AI ​​model. Based on the cell output of the AI ​​model, cell selection and cell reselection can be performed directly. If the AI ​​model outputs a recommended beam, the UE can select that beam when camping on that cell.

[0400] The UE inputs the current cell's configuration information, along with measurement results from the serving cell and neighboring cells, into the AI ​​model. The UE then remeasures the cell list output by the AI ​​model and performs cell selection and cell reselection based on existing selection criteria. If the AI ​​model outputs a recommended beam list, the UE selects the beam with the best quality to camp on based on the measurement results.

[0401] The wireless communication method provided in this application can be implemented as including, but not limited to, the following embodiments one to five.

[0402] Example 1: Acquisition of AI Models for Cell Selection and Cell Reselection

[0404] Method 1: The UE obtains AI model-related information used for cell selection and / or cell reselection through system broadcast messages. Among these,

This configuration can be done in a dedicated SIB message containing AI model configuration information for cell selection and cell reselection, or it can be placed in the SIB message used for cell selection and cell reselection.

[0406] The system broadcast message may include an indication message indicating whether the cell supports AI-based cell selection and / or cell reselection;

[0407] System broadcast messages may also include indications to indicate whether neighboring cells support AI-based cell selection and / or cell reselection.

[0412] When a UE transitions from connected mode to idle mode or inactive mode, the UE obtains AI-based cell selection and / or cell reselection information via the RRCRelease message, including one or more of the following:

[0413] An indication message to indicate whether the UE should perform AI-based cell selection and / or cell reselection;

[0415] Method 3: After the UE enters the connected state, it obtains relevant information about the AI ​​model used for cell selection and / or cell reselection;

[0417] The UE obtains AI model-related information for cell selection and / or cell reselection through connected-state reconfiguration messages, such as the RRCReconfiguration message.

[0418] When a UE performs a cell handover in connected mode, it obtains information related to the AI ​​model used for cell selection and / or cell reselection in the target cell through reconfiguration messages such as RRCReconfiguration messages.

[0451] j7. Recommended beam priority for the target cell;

[0452] j8. The effective period of the recommended information.

[0453] Example 3: AI-based Cell Selection

[0454] After the UE obtains the AI ​​model for cell selection and / or cell reselection, if the cell in which the UE is located is within the valid area of ​​the AI ​​model (if configured), the UE can perform AI-based cell selection:

[0455] 1. When the UE selects a new PLMN or SNPN, and has stored valid AI model information for cell selection and / or cell reselection, as well as previous frequency information, the UE performs AI-based cell selection.

[0456] 2. The UE inputs the instruction information for cell selection into the model, and inputs the measurement results of the stored frequency point list within the most recent time T into the AI ​​model, starts the AI ​​model calculation timer (which can be the same as or different from the timer for cell reselection, and the timer length is T2), and waits for the AI ​​model to output the results.

[0457] 3. If the AI ​​model outputs a cell, the UE can directly select that cell to perform camping.

[0458] 4. If the AI ​​model outputs multiple cells and their corresponding priorities, the UE can select the higher priority cell to camp on based on the priority.

[0459] 5. Based on 3 and 4, the UE can perform further measurement and verification on the recommended cells. If the signal quality (RSRP and / or RSRQ) of the cell is higher than a threshold, the UE selects the cell to camp on; otherwise, the UE exits the AI-based cell selection process and executes the existing cell selection process.

[0460] 6. If the AI ​​model does not output any cell, or if the AI ​​model outputs an indication of being camped in any cell, the UE enters the state of being camped in any cell.

[0461] 7. If the UE does not receive the output of the AI ​​model when the Timer expires, the UE exits the AI-based cell selection process and reverts to the existing cell selection process.

[0462] 8. When the UE camps on a cell, the UE inputs an AI-based cell selection success indication message, or the UE inputs an AI-based cell reselection indication message, and executes the AI-based cell reselection process.

[0463] Example 4: AI-based Cell Reselection

[0464] After the UE obtains the AI ​​model for cell selection and / or cell reselection, if the cell where the UE is located is within the effective area of ​​the AI ​​model, the UE performs AI-based cell reselection. The UE directly performs cell reselection based on the results output by the AI ​​model.

[0465] 1. The UE, according to the input configuration requirements of the AI ​​model, inputs the currently camped cell identifier, executes the AI-based cell reselection instruction information, and other configuration information, as well as the measurement results of the serving cell and neighboring cells within the most recent T1 time period, either at a T3 period or according to the model instruction. Alternatively;

[0466] The UE determines whether to perform a measurement based on the indication information from the AI ​​model and inputs the measurement results into the AI ​​model. This indication information can be a single bit of indication information, or it can indicate the frequency point of the measurement and the measurement duration.

[0467] 2. If the input configuration of the AI ​​model instructs the UE to input the beam measurement results of each cell, the UE will input the beam measurement results of the serving cell and the adjacent cell, as well as the beam index, into the AI ​​model.

[0468] 3. The UE inputs the RSRP measurement results and / or RSRQ measurement results of the serving cell and neighboring cells according to the configuration of the AI ​​model.

[0469] 4. After the UE inputs the measurement results into the AI ​​model, it starts a timer (duration set to T2) to wait for the model output. If the timer expires and the AI ​​model does not output, the UE re-inputs the data within the latest time period T1 and restarts the timer. When the maximum number of times N1 is reached, the UE exits the AI-based cell reselection and executes the existing cell reselection process.

[0470] 5. Based on the output of the AI ​​model, the UE can perform the following actions:

[0471] A. Instruct the UE to perform cell reselection and indicate a target cell ID. The UE directly reselects to that cell.

[0472] B. Instructs the UE to perform cell reselection and indicates multiple target cells and their corresponding priorities (optional). Among these cells, the UE can select the cell with the highest priority to perform cell reselection, or select the cell with the highest signal quality to perform cell reselection according to the signal quality order of these cells.

[0473] C. If the UE is rejected when camping on a cell recommended by the AI ​​model, the UE will not consider that cell for 300 seconds and will feed back the cell ID and the rejection information to the AI ​​model.

[0474] D. If the UE is instructed not to perform cell reselection, the UE will input the measurement results into the AI ​​model according to the configured period, and then determine whether to perform cell reselection based on the output of the AI ​​model.

[0475] In addition to indicating the cell to be reselected by the UE, the AI ​​model can also indicate the beam information selected by the UE, and the UE selects the beam of the cell to camp on that cell.

[0476] Example 5: AI-based Cell Reselection

[0477] After the UE obtains the AI ​​model for cell selection and / or cell reselection, if the cell where the UE is located is within the effective area of ​​the AI ​​model, the UE performs AI-based cell reselection. The UE re-evaluates based on the output of the AI ​​model and then performs cell reselection.

[0478] 1. The UE, according to the input configuration requirements of the AI ​​model, inputs the currently camped cell identifier, executes the AI-based cell reselection instruction information, and other configuration information, as well as the measurement results of the serving cell and neighboring cells within the most recent T1 time period, either at a T3 period or according to the model instruction. Alternatively;

[0479] The UE determines whether to perform a measurement based on the indication information from the AI ​​model and inputs the measurement results into the AI ​​model. This indication information can be a single bit of indication information, or it can indicate the frequency point of the measurement and the measurement duration.

[0480] 2. If the input configuration of the AI ​​model instructs the UE to input the beam measurement results of each cell, the UE will input the beam measurement results of the serving cell and the adjacent cell, as well as the beam index, into the AI ​​model.

[0481] 3. The UE inputs the RSRP measurement results and / or RSRQ measurement results of the serving cell and neighboring cells according to the configuration of the AI ​​model.

[0482] 4. After the UE inputs the measurement results into the AI ​​model, it starts a timer (duration set to T2) to wait for the model output. If the timer expires and the AI ​​model does not output, the UE re-inputs the data within the latest time period T1 and restarts the timer. When the maximum number of times N1 is reached, the UE exits the AI-based cell reselection and executes the existing cell reselection process.

[0483] 5. Based on the output of the AI ​​model, the UE can perform the following actions:

[0484] A. The UE is instructed to perform cell reselection, and multiple target cells are specified. The UE then measures the recommended cell list again and decides whether to perform cell reselection based on the measurement results and existing cell reselection criteria.

[0485] B. The cells output by the AI ​​model are for reference only; the UE needs to perform further verification. When the AI ​​model outputs recommended cells or a list of cells, the UE performs measurements on those cells. If the measurement result of that cell is higher than a threshold configured by the network (different thresholds may be configured for co-frequency cells, high-priority cells, and low-priority or same-priority cells), the UE reselects that cell. Otherwise, the UE inputs an indication that the recommended cell does not meet the requirements into the AI ​​model, inputs the measurement results of the serving cell or neighboring cells within the most recent T1 time period into the AI ​​model, and starts a timer to wait for the AI ​​model to output. If the number of times the AI ​​model recommends cells that do not meet the requirements reaches the network-configured threshold N2, the UE exits the AI-based cell reselection process.

[0486] C. If the UE is rejected when camping on a cell recommended by the AI ​​model, the UE will not consider that cell for 300 seconds and will feed back the cell ID and the rejection information to the AI ​​model.

[0487] D. If the UE is instructed not to perform cell selection, the UE will input the measurement results into the AI ​​model according to the configured period, and then determine whether to perform cell reselection based on the output of the AI ​​model.

[0488] E. If the AI ​​model recommends a beam, the UE needs to perform a second measurement and verification. The UE should take similar steps as described above to verify whether the quality of the recommended beam meets the requirements. If it does not meet the requirements, the UE can provide feedback to the AI ​​model. If the number of times the requirements are not met reaches the configured threshold, the UE will not consider the beam information recommended by the AI ​​model.
