[0064] 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.

[0065] Figure 1 is a schematic diagram of an application scenario of an embodiment of this application.

[0066] 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.

[0067] 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.

[0068] 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., user equipment (UE)) located within that coverage area.

[0069] Network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0070] 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.

[0071] For example, the terminal device 110 can refer to an access terminal, UE, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user equipment. The access terminal can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, IoT device, satellite handheld terminal, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a 5G network, or terminal device in a future evolved network, etc.

[0072] Terminal device 110 can be used for device-to-device (D2D) communication.

[0073] The wireless communication system 100 may further include a core network device 130 that communicates with the base station. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0074] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

[0076] 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.

[0077] It should be noted that Figure 1 is merely an example illustrating the system to which this application applies. Of course, the method shown in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. It should also be understood that "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a related relationship. For example, A instructing B can mean that A directly instructs B, for example, B can be obtained through A; it can also mean that A indirectly instructs B, for example, A instructs C, B can be obtained through C; or it can mean that there is a related relationship between A and B. It should also be understood that "correspondence" mentioned in the embodiments of this application can indicate a direct or indirect correspondence between two things, or an related relationship between two things, or a relationship of instruction and being instructed, configuration and being configured, etc. It should also be understood that the "predefined" or "predefined rules" mentioned in the embodiments of this application can be implemented by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices), and this application does not limit the specific implementation method. For example, predefined can refer to those defined in a protocol.

[0078] 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.

[0079] Layer 1 / L2 Triggered Mobility (LTM)

[0080] In Releases (R) 15 to R17, the NR system only supported Layer 3 (Radio Resource Control, RRC) mobility. Starting with R18, NR standardized enhancements to LTM. From the physical layer (Layer 1 (L1)), the UE pre-measures multiple candidate cells (including the current serving cell) using downlink measurement resources configured by the network (NW), and then reports the measurement results to the NW, i.e., the network equipment. The NW then indicates the selected candidate cell (i.e., the target cell) and / or the selected beam via a cell handover command.

[0081] For measurement and reporting, the UE can perform measurements in multiple candidate cells configured in the NW (including the current serving cell) and provide up to M x L ​​measurement results in a single report (depending on the UE's capabilities, where L is the number of candidate cells and M is the number of beams in each cell). Clearly, measuring a large number of candidate cells requires significant overhead from reference signals and latency for the UE to measure these reference signals, since the UE often cannot simultaneously measure multiple beams from multiple candidate cells.

[0082] After the UE completes the measurement and reports the measurement results to the NW, the NW can instruct the UE to switch to the target cell through the Media Access Control-Control Element (MAC CE) of the Cell Switch Command (CSC). The CSC includes at least the target cell information (such as candidate cell index) and / or the selected beam information (i.e. indicated by one or more Unified Transmission Configuration Indication (TCI) state identifiers).

[0083] Artificial Intelligence (AI) / Machine Learning (ML) Models

[0084] A neural network is a computational model composed of multiple interconnected neurons. The connections between nodes represent weighted sums from the input signal to the output signal, called weights. Each node performs a weighted summation on different input signals and outputs the result through a specific activation function. The neuron structure is shown in Figure 2. Weights w1 to wn and b are used to perform a weighted summation on a1 to an and 1, respectively. The result of this weighted summation is then output through the activation function f to obtain the output t.

[0085] A simple neural network, as shown in Figure 3, consists of an input layer 301, a hidden layer 302, and an output layer 302. Through different connections, weights, and activation functions of multiple neurons, different outputs can be generated, thus fitting a mapping relationship from input to output. Each node in the previous level is connected to all its nodes in the next level. This fully connected model can also be called a deep neural network (DNN). This neural network (NN) model can perform beam prediction in the spatial domain.

[0086] A neural network (NN) model can be trained and obtained through the processes of dataset construction, training, validation, and testing. It is assumed that the NN model has already been trained in advance using either offline or online methods. It's important to note that offline and online training are not mutually exclusive. Firstly, the NN can obtain a static training result through offline training on the dataset; this can be referred to as offline training. During the use of the NN by the NN or the user appliance (UE), as the UE performs further measurements and / or reports, the NN model can continue to collect more data for real-time online training to optimize its parameters and achieve better inference and prediction results.

[0087] It should be noted that a beam can refer to either a transmit beam or a receive beam. In protocols, transmit / receive spatial filters are generally used instead of the implementation-oriented term transmit / receive beam. In the embodiments of this application, beam and spatial filter are interchangeable.

[0088] For a model, its output can be understood as inference or prediction, where inference and prediction mean the same thing and can be used interchangeably.

[0089] In the Release 18 (R18) standardization, the UE is responsible for a large number of downlink measurements and reports the measurement results to the network controller (NW). Since R18 does not define the reporting of event-triggered mobility events, the UE can only perform downlink multi-cell and / or multi-beam measurements step by step and report a large number of measurement results to the NW, lacking autonomy and selectivity in reporting.

[0090] Assuming 3GPP defines LTM mobility events in subsequent versions, the UE will still need to perform numerous measurements to determine whether the conditions for triggering a mobility event are met. The measurement process itself will consume significant measurement resources and incur overhead for the UE, such as the time and frequency resources used during beam scanning. Furthermore, during extensive measurements, the UE may require Measurement Gap protection, necessitating a temporary halt to downlink reception and uplink transmission within the cell, thus impacting normal communication.

[0091] Therefore, using AI / ML technology to predict whether LTM events will occur and related information about LTM events can be a technical approach to solving the LTM problem.

[0092] 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. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0093] The wireless communication method provided in this application embodiment is applied to a terminal device, as shown in Figure 4, and includes:

[0094] S401. The terminal device predicts first prediction information based on one or more first measurement results. The first prediction information is related to one or more first prediction results. The first measurement results are measurement results obtained by measuring a first cell. The first prediction results are measurement results of a second cell predicted based on the one or more first measurement results.

[0095] The terminal device measures a first number of first cells and obtains the measurement results of each first cell in the first number of first cells, that is, obtains a first number of first measurement results. The first number is an integer greater than or equal to 1.

[0096] Understandably, for a first cell, the terminal device measures one or more spatial filters corresponding to the first cell and obtains the measurement result of the first cell based on the measurement results of each spatial filter.

[0097] For a given cell, the terminal device performs measurements on the cell using one or more measurement resources. Understandably, one measurement resource corresponds to one spatial filter.

[0098] The first measurement result in this application embodiment may be the measurement result obtained by performing Layer 1 measurement on the first cell. The first measurement result may include one or more of the following: L1-Reference Signal Receiving Power (RSRP), L1-Reference Signal Receiving Power (RSRQ), L1-Received Signal Strength Indication (RSSI), L1-Signal to Interference plus Noise Ratio (SINR), and Signal-to-Noise Ratio (SNR).

[0099] The measurement resources of the first cell may be Channel State Information-Reference Signal (CSI-RS) resources and / or Synchronization Signal and PBCH Block (SSB) resources.

[0100] After determining a first quantity of first measurement results, the terminal device makes a prediction of first prediction information based on the first quantity of first measurement results. The first prediction information is related to the first prediction results. Understandably, the first prediction information is determined based on the first prediction results.

[0101] The first prediction result is the measurement result of the second cell predicted based on a first number of first measurement results. The first number of first measurement results can predict one or more first prediction results, and different first prediction results correspond to different second cells. It is understood that the first prediction result is the measurement result of the second cell, but it is not a measurement result obtained by measuring the second cell; rather, it is a measurement result predicted or inferred based on the first number of first measurement results.

[0102] Understandably, the second community may belong to the first community of the first quantity or may not belong to the first community of the first quantity.

[0103] In one example, the terminal device obtains first prediction information related to the prediction results of cells 4 and 5 based on the measurement results of cells 1, 2 and 3, wherein the prediction results of cells 4 and 5 are predicted based on the measurement results of cells 1, 2 and 3.

[0104] In one example, the terminal device obtains first prediction information related to the prediction results of cell 3 and cell 4 based on the measurement results of cell 1, cell 2 and cell 3, wherein the prediction results of cell 3 and cell 4 are predicted based on the measurement results of cell 1, cell 2 and cell 3.

[0105] In some embodiments, a first prediction model is deployed in the terminal device. The first prediction model can be expressed as a function, a deep learning model, a neural network model (e.g., DNN, CNN, RNN), or various other models. The terminal device inputs a first number of first measurement results into the first prediction model to obtain the first prediction information output by the first prediction model.

[0106] The wireless communication method provided in this application embodiment involves a terminal device determining first prediction information related to the predicted measurement results of one or more second cells based on one or more first measurement results. This allows the device to predict the measurement results of one or more second cells while measuring one or more first cells. Based on the predicted measurement results of one or more second cells, the terminal device obtains the first prediction information. This allows the terminal device to obtain the first prediction information without needing to measure one or more second cells, thereby reducing the overhead of reference signals used for cell measurement.

[0107] In some embodiments, based on FIG4, this application provides a wireless communication method applied to a terminal device, as shown in FIG5, including:

[0108] S501, the terminal device sends second information to the network device, the second information being used to indicate a second mobility event, the second mobility event being the first mobility event that triggered the reporting, and the first mobility event being related to the first prediction result.

[0109] The first prediction information includes a first mobility event, which is a mobility event related to the first prediction result. A mobility event can be understood as an event related to the mobility of the terminal device.

[0110] In some embodiments, this application provides a wireless communication method applied to a network device, as shown in FIG6, including:

[0111] S601. The network device receives second information sent by the terminal device. The second information is used to indicate a second mobility event. The second mobility event is a reported first mobility event. The first mobility event is related to a first prediction result. The first prediction result is a measurement result of a second cell predicted based on one or more first measurement results. The first measurement result is a measurement result obtained by measuring the first cell.

[0112] Wherein, the one or more first measurement results are used to predict first prediction information, and the first prediction information is related to one or more of the first prediction results.

[0113] The wireless communication method shown in Figure 5 or Figure 6 will be described in further detail below.

[0114] If the terminal device determines that a first mobility event has occurred based on the first prediction result, and the first mobility event triggers reporting, then the terminal device needs to report the first mobility event to the network device. At this time, the terminal device sends second information to the network device, which indicates the reported first mobility event, i.e., the second mobility event.

[0115] The network device receives the second information sent by the terminal device and determines that a second mobility event has occurred on the terminal device based on the second information.

[0116] Understandably, the terminal device may determine one or more first mobility events based on the first prediction result, and all or part of the determined one or more first mobility events may be second mobility events.

[0117] In this embodiment of the application, if the terminal device predicts a second mobility event based on one or more first measurement results, it can directly report the second mobility event to the network device without reporting the first measurement results to the network device, thereby reducing signaling overhead.

[0118] In some embodiments, the first prediction information includes one or more of the following:

[0119] First indication information, the first indication information is used to indicate whether one or more first mobility events have occurred, the first mobility events being related to the first prediction result;

[0120] The second indication information is used to indicate the event type of the first mobility event that occurred;

[0121] The first information indicates the first prediction result corresponding to the first mobility event that occurred.

[0122] In this embodiment of the application, the first indication information can be used to indicate whether one or more first mobility events have occurred on the terminal device.

[0123] Understandably, different values ​​of the first indication information are used to indicate that one or more first mobility events have occurred, or that no first mobility event has occurred.

[0124] In some embodiments, the one or more first mobility events are mobility events configured or preset by the network device. In this case, the first indication information is used to indicate whether the mobility events configured or preset by the network device have occurred.

[0125] If a first mobility event occurs, the second indication information is used to indicate which first mobility event occurred. Understandably, if multiple first mobility events occur, the first prediction information includes multiple second indication information, with different second indication information indicating different event types of the first mobility events.

[0126] The first information is used to indicate the first prediction result corresponding to the first mobility event that has occurred.

[0127] In some embodiments, the one or more first mobility events include one or more of the following first events:

[0128] First event A: The one or more second cells corresponding to the one or more first mobility events include the serving cell, and the link performance of the serving cell based on layer 1 measurement and / or prediction is better than a first threshold;

[0129] First event B: The one or more second cells include a serving cell, wherein the link performance of the serving cell based on layer 1 measurement and / or prediction is weaker than a second threshold;

[0130] First event C: The one or more second cells include candidate cells and serving cells, and the link performance of the candidate cells based on layer 1 measurement and / or prediction is better than the link performance of the first cell, wherein the link performance of the first cell is the link performance of the serving cell plus a first offset;

[0131] First event D: The one or more second cells include candidate cells, and the link performance of the candidate cells based on layer 1 measurements and / or predictions is better than the third threshold;

[0132] First event E: The one or more second cells include candidate cells and serving cells, where the link performance of the serving cell based on layer 1 measurement and / or prediction is weaker than the fourth threshold, and the link performance of the candidate cells based on layer 1 measurement and / or prediction is better than the fifth threshold.

[0133] First event F, the one or more second cells include candidate cells, the interference of the candidate cells based on layer one measurement and / or prediction is stronger than a first interference threshold.

[0134] Understandably, the first event is a cell-level mobility event related to the link performance of the serving cell and / or the link performance of the candidate cell.

[0135] The terminal device predicts one or more first mobility events based on one or more first measurement results, including one or more of first events A to first events F.

[0136] For the threshold values, such as the first threshold to the fifth threshold and the first interference threshold involved in the first events A to F, the values ​​of different threshold values ​​can be the same or different.

[0137] In this embodiment of the application, the link performance of a cell can be represented by one or more parameters that characterize the link quality of the cell, namely L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR.

[0138] Understandably, if a first measurement result and a first prediction result exist for the second cell, the terminal device can determine whether a first mobility event has occurred in the second cell based on the first measurement result and / or the first prediction result.

[0147] Understandably, the spatial filter of a serving cell is divided into a serving spatial filter and a candidate spatial filter, with the spatial filter of a candidate cell being the candidate spatial filter.

[0148] The terminal device predicts one or more first mobility events based on one or more first measurement results, including one or more of second events A to second events F.

[0149] For the threshold values ​​of the sixth to tenth thresholds and the second interference threshold involved in the second events A to F, the values ​​of different threshold values ​​can be the same or different.

[0150] In this embodiment of the application, the performance of the spatial filter can be represented by one or more parameters that characterize the link quality of the spatial filter, namely L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR.

[0151] In this embodiment of the application, the first mobility event determined by the terminal device based on one or more first measurement results can be a cell-level mobility event or a spatial filter-level mobility event.

[0152] If the terminal device determines multiple first mobility events based on one or more first measurement results, then all of the multiple first mobility events may be cell-level mobility events, all of them may be spatial filter-level mobility events, or some may be cell-level mobility events and some may be beam-level mobility events.

In one example, if the first mobility event includes first event A and first event D, the first information includes: the index of the serving cell and / or the link quality of the serving cell; and the index of the candidate cell and / or the link quality of the candidate cell.

[0170] Understandably, if the first mobility event includes a spatial filter-level first mobility event, then the first information corresponding to the first mobility event includes the cell information and / or spatial filter information corresponding to the first mobility event. The cell information includes: cell index and / or cell link quality, and the spatial filter information includes: spatial filter index and / or spatial filter link quality.

[0171] If the first mobility event at the spatial filter level is related to the serving spatial filter, then the cell information included in the first information is the information of the serving cell, and the spatial filter information included in the first information is the information of the serving spatial filter. That is, the first information includes: the index of the serving cell and / or the link quality of the serving cell, and / or, the index of the serving spatial filter and / or the link quality of the serving spatial filter.

[0172] In one example, if the first mobility event that occurs includes the second event A, then the first information includes the index of the service space filter and / or the link quality of the service space filter.

[0173] In one example, if the first mobility event includes the second event A, then the first information includes the index of the serving cell and / or the link quality of the serving cell.

[0174] In one example, if the first mobility event includes the second event A, then the first information includes the index of the serving cell and / or the link quality of the serving cell, and the index of the serving space filter and / or the link quality of the serving space filter.

[0175] If the first mobility event at the spatial filter level is related to a candidate spatial filter, then the cell information included in the first information is the information of the candidate cell, and the spatial filter information included in the first information is the information of the candidate spatial filter. That is, the first information includes: the index of the candidate cell and / or the link quality of the candidate cell, and / or, the index of the candidate spatial filter and / or the link quality of the candidate spatial filter.

[0176] In one example, if the first mobility event includes the second event D, then the first information includes: the index of the candidate spatial filter and / or the link quality of the candidate spatial filter.

[0177] In one example, if the first mobility event includes the second event D, then the first information includes: the index of the candidate cell and / or the link quality of the candidate cell.

[0178] In one example, if the first mobility event includes the second event D, then the first information includes: the index of the candidate cell and / or the link quality of the candidate cell, and the index of the candidate spatial filter and / or the link quality of the candidate spatial filter.

In other words, the first information includes:

[0181] And, the index of candidate cells and / or the link quality of candidate cells, and / or, the index of candidate spatial filters and / or the link quality of candidate spatial filters.

[0182] In this embodiment of the application, if the first mobility event includes a cell-level first mobility event and a spatial filter-level first mobility event, then the first information corresponding to the cell-level first mobility event includes cell information, and the first information corresponding to the spatial filter-level first mobility event includes spatial filter information.

[0183] It should be noted that after the terminal device predicts the first prediction information, it can report the first mobility event indicated by the first prediction information to the network device, or it can report the first mobility event used for reporting, i.e., the second mobility event, from the first mobility event indicated by the first prediction information to the network device.

[0184] In one example, the reported mobility events include: first event B, first event C, first event D, second event B, second event C, and second event D. If the first prediction information indicates that the first event A has occurred, the terminal device will not send the second information, and the network device will not receive the second information.

[0185] In one example, the reported mobility events include: first event B, first event C, first event D, second event B, second event C, and second event D. If the first prediction information indicates that the first event A and the second event B have occurred, the terminal device sends second information, and the sent second information indicates the second event B.

[0186] In one example, the reported mobility events include: first event B, first event C, first event D, second event B, second event C, and second event D. If the first prediction information indicates that the first event B and the second event B have occurred, the terminal device sends second information, and the sent second information indicates the first event B and the second event B.

[0187] In some embodiments, when a second mobility event is reported on a terminal device, the second mobility event is:

[0188] Determined by the terminal device; or,

[0189] The network device indicates; or,

[0190] Predefined.

[0191] If the second mobility event is determined by the terminal device, the terminal device may decide whether to report the first prediction result of the mobility event.

[0192] If the second mobility event is indicated by a network device, the terminal device reports the first prediction result of the mobility event according to the configuration or indication of the network device.

[0193] If the second mobility event is predefined, the terminal device reports the first prediction result of the mobility event according to the predefined parameters in the protocol.

[0194] In one example, when the first prediction information indicates that the first event A has occurred, the terminal device does not need to report or trigger subsequent LTM mobility operations.

[0195] In one example, when the first prediction information indicates that a first event C has occurred, the terminal reports the first prediction result of the first event C.

[0196] In some embodiments, the second information is transmitted via one or more of the following signaling:

[0197] Physical layer control signaling;

[0198] Media Access Control (MAC) layer control unit (MAC CE);

[0199] Mobility-related signaling in the Radio Resource Control (RRC) layer.

[0200] In this embodiment of the application, the terminal device may use physical layer or higher control signaling to carry the second information.

[0201] In some embodiments, when a terminal device reports a second mobility event, the reporting resource may be a periodic Physical Uplink Control Channel (PUCCH).

[0202] In some embodiments, the first uplink resource for reporting the second information is pre-configured by the network device for the terminal device, and the terminal device does not need to request the resource.

[0203] In some embodiments, the second information may be included in the MAC CE at the MAC layer, or in mobility-related signaling at a higher layer (such as the RRC layer).

[0204] In some embodiments, for a second mobility event, the second information includes one or more of the following:

[0205] The third indication information is used to indicate the event type of the second mobility event;

[0206] The first information corresponding to the second mobility event.

[0207] The description of the first piece of information can be found in the preceding description, and will not be repeated here.

[0208] In some embodiments, based on FIG5, this application provides a wireless communication method applied to a terminal device, as shown in FIG7, including:

[0209] S701, the terminal device receives a cell handover command sent by the network device, the cell handover command carrying third information indicating the target cell, the third information being related to the second information.

[0210] In some embodiments, based on FIG6, this application provides a wireless communication method applied to a network device, as shown in FIG8, including:

[0211] S801, the network device sends a cell handover command to the terminal device, the cell handover command carrying third information indicating the target cell, the third information being related to the second information.

[0212] After receiving the second information sent by the terminal device, the network device, in response to the second information, determines the third information based on or without the second information, and sends the third information to the terminal device. The third information is used to indicate the target cell.

[0213] Optionally, the network device sends third information to the terminal device via a Cell Switch Command (CSC).

[0214] Optionally, the cell handover command itself has a MAC CE bearer, which contains a TCI state ID and a candidate cell index, wherein the TCI state ID is used to indicate the candidate beam and the candidate cell index is used to indicate the target cell.

[0215] After receiving a cell handover command from the network device, the terminal device completes the cell handover operation to the target cell within a certain period of time.

[0216] In this embodiment of the application, the target cell indicated by the third information may or may not belong to the first cell. It is understood that if the target cell belongs to the first cell, the terminal device has measured the target cell; if the target cell does not belong to the first cell, the terminal device has not measured the target cell.

[0217] In some embodiments, if the target cell indicated by the third information does not belong to the first cell, the third information is further used to indicate a first measurement resource, which is used for the measurement of the target cell and / or the reporting of measurement results.

[0218] If the target cell indicated by the third information is a cell that the terminal device has not previously measured, the cell handover command may additionally indicate a set of measurement resources, namely the first set of measurement resources. The terminal device can use the first set of measurement resources to complete the measurement and / or reporting of the target cell and / or target beam. The first set of measurement resources may include a set of CSI-RS resources and / or SSB resources.

[0219] In one example, the terminal device can complete downlink synchronization and adjust the downlink receive spatial filter, etc., by measuring the SSB resource in the first measurement resource.

[0220] In one example, the terminal device can track time and frequency by measuring the CSI-RS of the target cell, or obtain the CSI information of the cell in advance and feed it back to the network device.

[0221] In some embodiments, based on FIG4, FIG5, or FIG7, this application provides a wireless communication method, as shown in FIG9, including:

[0222] S901, the terminal device receives first configuration information sent by the network device. The first configuration information is used to configure one or more first sets and / or one or more second sets. The one or more first sets include second measurement resources corresponding to one or more first cells. The one or more second sets include prediction resources corresponding to one or more third cells. The second cell is one of the one or more third cells.

[0223] In some embodiments, based on FIG6 or FIG8, this application provides a wireless communication method, as shown in FIG10, including:

[0224] S1001, the network device sends first configuration information to the terminal device. The first configuration information is used to configure one or more first sets and / or one or more second sets. The one or more first sets include second measurement resources of one or more first cells. The one or more second sets include prediction resources of one or more third cells. The second cell is one of the one or more third cells.

[0225] One or more first sets can be labeled as measurement set Set B n (1 <= n <= N), one or more first sets, i.e., Set B 1、 Set B2…Set B N This includes the measurement resources of the first number of first cells, i.e., the second measurement resources.

[0226] One or more second sets can be labeled as prediction sets Set A n (1 <= n <= M), one or more second sets, i.e., Set A 1、 Set A2…Set A M It includes the predicted resources of a second number of third cells, where the second cell is one of the third cells.

[0227] Understandably, the second cell corresponding to the first prediction result belongs to a second number of third cells corresponding to one or more second sets. The second cell corresponding to the first prediction information includes some or all of the cells in the second number of third cells. In other words, the second cell corresponding to the first prediction result should be from prediction set Set A. m The third cell corresponding to (1<=m<=M) was selected.

[0228] In some embodiments, one or more first cells correspond to one first set.

[0229] Understandably, a first set includes second measurement resources of one or more first cells, wherein a first cell includes one or more second measurement resources, and a second prediction resource corresponds to a spatial filter of the first cell.

[0230] In some embodiments, one or more third cells correspond to one of the second sets.

[0231] Understandably, a second set includes prediction resources for one or more third cells, wherein a third cell includes one or more prediction resources, and a prediction resource corresponds to a spatial filter for that third cell.

[0232] In some embodiments, the relationship between the second measurement resources included in one or more first sets and the prediction resources included in one or more second sets includes one of the following:

[0233] Relationship 1: The second measurement resources included in the first set do not contain the same resources as the predicted resources included in the second set.

[0234] Relationship 2: One first cell corresponds to one first set and one second set, where the first set is a subset of the second set.

[0235] In relation one, the second measured resource is different from the predicted resource.

[0236] In one example, the second measurement resource is a wide beam (few in number) based on SSB, and the prediction resource is a narrow beam (more in number) based on CSI-RS.

[0237] In relation 2, the first set and the third set correspond to the same cell. The first set is a subset of the third set, that is, the measurement resources corresponding to a cell are a subset of the corresponding prediction resources.

[0238] In one example, the first set corresponding to a cell includes 8 measurement resources, which correspond to 8 spatial filters, and the second set corresponding to the cell includes 64 prediction resources, which correspond to 64 beams.

[0239] In this embodiment of the application, the measurement resources corresponding to a cell are a subset of the prediction resources corresponding to that cell, which can reduce measurement overhead and latency.

[0240] In some embodiments, one third cell corresponds to one second set, and there is no corresponding first set.

[0241] For the third cell, there is no corresponding second measurement resource, so the measurement results of the third cell can only be predicted based on the measurement results of the first cell, i.e., other cells.

[0242] In some embodiments, the first configuration information is further configured to configure one or more of the following:

[0243] The third mobility event is a mobility event predicted by the one or more first measurement results;

[0244] The first uplink resource or the second uplink resource, wherein the first uplink resource is used to report the second mobility event, and the second uplink resource is used to transmit the first request, wherein the first request is used to request the first uplink resource, and the second mobility event is the first mobility event reported in the first prediction information.

[0245] The third mobility event is a mobility event that can be predicted based on one or more first measurement results.

[0246] The first uplink resource is the resource used by the terminal device to report the second mobility event. The second uplink resource is the resource used by the terminal device when requesting the first uplink resource.

[0247] Understandably, if the first configuration information includes a first uplink resource, the terminal device reports the second mobility event based on the first uplink resource configured in the first configuration information. If the first configuration information does not include a first uplink resource, the terminal device sends a first request based on the second uplink resource configured in the first configuration information to request the network device to schedule the first uplink resource to the terminal device. The first request may be a scheduling request (SR).

[0248] After receiving the first request, the network device can send uplink scheduling downlink control information (DCI) to the terminal device. The uplink scheduling DCI is used to schedule the first uplink resources.

[0249] In some embodiments, based on Figures 4, 5, 7, or 9, this application provides a wireless communication method, as shown in Figure 11, including:

[0250] S1101. The terminal device sends fourth information to the network device, the fourth information being used to indicate one or more of the following capabilities of the terminal device:

[0251] Whether the terminal device supports the measurement of one or more first measurement results and / or whether it supports the prediction of the first prediction information based on one or more first measurement results;

[0252] One or more fourth mobility events, wherein the fourth mobility events are mobility events that the one or more first measurement results support for prediction;

[0253] The first quantity is the number of first cells supported by the terminal device on a carrier;

[0254] The second quantity is the number of first sets supported by the terminal device on a carrier, and one first set includes second measurement resources corresponding to one or more first cells;

[0255] The third quantity is the number of the second set supported by the terminal device on a carrier; the second set is used to configure the prediction resources of the third cell; the third cell is the cell corresponding to the prediction result of the one or more first measurement results used for prediction.

[0256] In some embodiments, based on FIG6, FIG8, or FIG10, this application provides a wireless communication method applied to a network device, as shown in FIG11, including:

[0257] S1101, the network device receives fourth information sent by the terminal device, the fourth information being used to indicate one or more of the following capabilities of the terminal device:

[0258] Whether the terminal device supports the measurement of one or more first measurement results and / or whether it supports the prediction of the first prediction information based on one or more first measurement results;

[0259] One or more fourth mobility events, wherein the fourth mobility event is a mobility event that the terminal device supports predicting;

[0260] The first quantity is the number of first cells supported by the terminal device on a carrier;

[0261] The second quantity is the number of first sets supported by the terminal device on a carrier, and one first set includes second measurement resources corresponding to one or more first cells;

[0262] The third quantity is the number of the second set supported by the terminal device on a carrier, the second set being used to configure the prediction resources of the third cell; the third cell is the cell corresponding to the prediction result of the one or more first measurement results used for prediction.

[0263] In this embodiment of the application, the terminal device reports its measurement and prediction capabilities to the network device based on fourth information, wherein the measurement and prediction capabilities may include cell-level and / or spatial filter-level capabilities.

[0264] Here, the first mobility event, the second mobility event, the third mobility event, and the fourth mobility event are explained:

[0265] The first mobility event is a mobility event predicted by the terminal device based on one or more first measurement results;

[0266] The second mobility event is a mobility event predicted and reported by the terminal device based on one or more first measurement results;

[0267] The third mobility event is a mobility event that the terminal device configured by the network device can predict based on one or more first measurement results;

[0268] The fourth mobility event is a mobility event that the terminal device supports predicting.

[0269] Optionally, the fourth information includes fifth indication information, which is used to indicate whether the terminal device supports the measurement of the one or more first measurement results and / or whether it supports the prediction of the first prediction information based on the one or more first measurement results. If the fourth indication information indicates that the terminal device supports the measurement of the one or more first measurement results and supports the prediction of the first prediction information based on the one or more first measurement results, the fourth information is used to indicate other content. Alternatively, the fourth information does not include the fourth indication information. If other content is indicated, the terminal device is assumed to support the measurement of the one or more first measurement results and supports the prediction of the first prediction information based on the one or more first measurement results.

[0270] In this embodiment of the application, after receiving the fourth information, the network device can configure the first set and / or the second set based on the fourth information.

[0271] This application provides a wireless communication method applied to a terminal device, as shown in FIG12, including:

[0272] S1201. The terminal device sends one or more first measurement results to the network device. The first measurement results are measurement results obtained by measuring a first cell. The one or more first measurement results are used to predict first prediction information. The first prediction information is related to the one or more first prediction results. The first prediction results are measurement results of a second cell predicted based on the one or more first measurement results.

[0273] This application provides a wireless communication method applied to a terminal device, as shown in FIG13, including:

[0274] S1301. The network device receives one or more first measurement results sent by the terminal device, wherein the first measurement results are measurement results obtained by measuring the first cell;

[0275] S1302, the network device predicts first prediction information based on the one or more first measurement results, the first prediction information being related to the one or more first prediction results, and the first prediction result being the measurement result of the second cell predicted based on the one or more first measurement results.

[0276] The terminal device measures a first number of first cells and obtains the measurement results of each first cell in the first number of first cells, that is, obtains a first number of first measurement results. The first number is an integer greater than or equal to 1.

[0277] Understandably, for a first cell, the terminal device measures one or more spatial filters corresponding to the first cell and obtains the measurement result of the first cell based on the measurement results of each spatial filter.

[0278] For a given cell, the terminal device performs measurements on the cell using one or more measurement resources. Understandably, one measurement resource corresponds to one spatial filter.

[0279] The first measurement result in this application embodiment may be the measurement result obtained by performing Layer 1 measurement on the first cell. The first measurement result may include one or more of L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR.

[0280] The measurement resources for the first cell can be CSI-RS resources and / or SSB resources.

[0281] After the terminal device determines a first number of first measurement results, it reports the first number of first measurement results to the network device, so that the network device can make a prediction of the first prediction information based on the first number of first measurement results.

[0282] The first measurement result of the first quantity can be reported to the network device via uplink signaling. In some embodiments, the uplink signaling is reported in the form of spatial filter reporting in the physical layer uplink control information (UCI). The UCI can be carried via PUCCH or Physical Uplink Shared Channel (PUSCH). The uplink signaling can also be MAC CE or RRC signaling.

[0283] After receiving a first number of first measurement results, the network device predicts first prediction information based on the first number of first measurement results. The first prediction information is related to the first prediction results. Understandably, the first prediction information is determined based on the first prediction results.

[0284] The first prediction result is the measurement result of the second cell predicted based on a first number of first measurement results. The first number of first measurement results can predict one or more first prediction results, and different first prediction results correspond to different second cells. It is understood that the first prediction result is the measurement result of the second cell, but it is not a measurement result obtained by measuring the second cell; rather, it is a measurement result predicted or inferred based on the first number of first measurement results.

[0285] Understandably, the second community may belong to the first community of the first quantity or may not belong to the first community of the first quantity.

[0286] In some embodiments, a second prediction model is deployed in the network device. The second prediction model can be expressed as a function, a deep learning model, a neural network model, or various other models. The network device inputs a first number of first measurement results into the second prediction model to obtain first prediction information output by the first prediction model.

[0287] Understandably, the first prediction model and the second prediction model are prediction models deployed on the terminal device and network device sides, respectively, and the first prediction model and the second prediction model may have the same or different structures.

[0288] The wireless communication method provided in this application embodiment involves a terminal device performing a first number of first measurement results and reporting the measurement results to a network device. The network device determines first prediction information related to the predicted measurement results of one or more second cells based on one or more first measurement results, thereby obtaining the first prediction information without needing to measure one or more second cells, thus reducing the overhead of reference signals used for cell measurement.

[0345] In one example, if the first mobility event includes the second event A, then the first information includes the index of the serving cell and / or the link quality of the serving cell, and the index of the serving space filter and / or the link quality of the serving space filter.

[0346] If the first mobility event at the spatial filter level is related to a candidate spatial filter, then the cell information included in the first information is the information of the candidate cell, and the spatial filter information included in the first information is the information of the candidate spatial filter. That is, the first information includes: the index of the candidate cell and / or the link quality of the candidate cell, and / or, the index of the candidate spatial filter and / or the link quality of the candidate spatial filter.

[0354] In some embodiments, the transmission method of the plurality of first measurement results includes one of the following:

[0355] The first transmission method is to transmit according to a first order, wherein the first order is a pre-configured or predefined sorting of a first set, and a first set includes one or more second measurement resources corresponding to the first cell;

[0356] The second transmission method involves transmitting according to the first and second orders, where the second order is the sorting of the second measurement resources in the first set.

[0357] In this embodiment of the application, the terminal device may report multiple first measurement results based on a first transmission method or a second transmission method.

[0358] In the first transmission method, the terminal device reports according to the order of a pre-configured or arranged first set. The network device then determines the first set corresponding to the received measurement results according to the pre-configured or arranged first set order. In one example, the first order is Set B1, Set B2, ..., Set B n The terminal device first reports the measurement results of the measurement resources in Set B1, then reports the measurement results of the measurement resources in Set B2, and so on, until it reports the results of Set B1. N The measurement results of the measured resources in Set B1, Set B2, ..., Set B... are received by the network device in the following order: measurement results of the measured resources in Set B1, measurement results of the measured resources in Set B2, ..., Set B... N Measurement results of resources in China.

[0359] When multiple first measurement results are transmitted in a first order, each first measurement result includes a resource index and link quality, but may not include Set B. n The index.

[0360] In cases where multiple first measurement results are transmitted in the first order, avoid reporting Set B. n The index reduces reporting overhead, allowing more resource indexes and corresponding link quality to be reported.

[0361] In the second transmission mode, the terminal device not only follows the pre-configured or arranged first set Set B n The measurements are transmitted in the following order. For each first set, the measurement resources within the first set are also reported according to their order. The network determines the first set corresponding to the received measurement results based on the pre-configured or arranged order of the first sets, and for each first set, the measurement resources corresponding to the received measurement results are determined according to their order. In one example, the first order is Set B1, Set B2, ..., Set B... n The terminal device first reports the measurement results of the measurement resources in Set B1, then reports the measurement results of the measurement resources in Set B2, and so on, until it reports the results of Set B1. N The measurement results of the measured resources in Set B n Set B n There are a total of 16 resources in the system, and the link quality corresponding to the 16 measurement resources can be reported according to a specific resource sorting. The second order can be the sorting order of the measurement resources in the first set from high to low or from low to high according to the resource index.

[0362] When multiple first measurement results are transmitted in a first order, each first measurement result includes link quality but may not include Set B.n Indexes and resource indexes.

[0363] When multiple first measurement results are transmitted according to a first order and a second order, the reporting overhead of resource index usage can be further reduced.

[0364] Understandably, since the measurement resources are configured by the network device, the network device can determine the resource index corresponding to the reported link quality and the index of the first set.

[0365] In some embodiments, the transmission method of the plurality of first measurement results includes:

[0366] The third transmission method is based on reporting instance transmission, where one reporting instance includes multiple spatial filter reporting instances.

[0367] When a terminal device reports multiple first measurement results according to a third transmission method, the reported multiple first measurement results are divided into multiple reporting instances. One reporting instance includes multiple spatial filter reporting instances. The network side connects the multiple spatial filter reporting instances in series to obtain one reporting instance, and completes the reception of multiple first measurement results by receiving multiple reporting instances.

[0368] The spatial filter reporting instance can include the link quality of the spatial filter. Measurement results are placed in the spatial filter reporting instance and sent from the terminal device to the network device via the uplink control channel or data channel.

[0369] In this embodiment of the application, the first transmission method and the second transmission method increase the capacity of the reported content by reducing the reported content, and the third transmission method can be used in combination with the first transmission method or the second transmission method.

[0370] In some embodiments, the reporting instance includes fourth indication information, which is used to indicate the order of the plurality of spatial filter reporting instances included in the reporting instance.

[0371] In the reported instance, the terminal device informs the network device which spatial filter reporting instances were used sequentially to report multiple first measurement results.

[0372] In some embodiments, the multiple spatial filter reporting instances included in the reporting instance are configured by the network device.

[0373] Network devices can inform terminal devices, either through pre-configuration or instruction, which (more than one) spatial filter reporting instances to use to report multiple first measurement results.

[0381] After receiving a cell handover command from the network device, the terminal device completes the cell handover operation to the target cell within a certain period of time.

[0382] In this embodiment of the application, the target cell indicated by the fifth information may or may not belong to the first cell. It is understood that if the target cell belongs to the first cell, the terminal device has measured the target cell; if the target cell does not belong to the first cell, the terminal device has not measured the target cell.

[0383] In some embodiments, if the target cell does not belong to the first cell, the fifth information is further used to indicate a first measurement resource, which is used for the measurement of the target cell and / or the reporting of measurement results.

[0384] If the target cell indicated by the fifth information is a cell that the terminal device has not previously measured, the cell handover command may additionally indicate a set of measurement resources, namely the first set of measurement resources. The terminal device can use the first set of measurement resources to complete the measurement and / or reporting of the target cell and / or target beam. The first set of measurement resources may include a set of CSI-RS resources and / or SSB resources.

[0410] Considering the UE's Radio Resource Management (RRM) measurement behavior in Layer 1, define the mobility events triggered by Layer 1 / Layer 2 measurements.

[0411] Events are divided into beam-level events and cell-level events.

[0412] It should be noted that cell-level measurement results are calculated based on beam-level measurement results. For example, for cell-level L1-RSRQ, when a UE measures N beams (based on Channel State Information-Reference Signal (CSI-RS) resources and / or SSB resources) within a candidate cell, the number of resources with L1-RSRP greater than a certain RSRP threshold is S. Then, a linear average of these S L1-RSRP values ​​is performed to obtain the averaged cell-level L1-RSRP.

[0413] In some embodiments, cell-level predicted mobility events are defined as follows:

[0414] a. The link performance of the serving cell based on Layer 1 measurements and / or predictions is better than a specific threshold;

[0415] b. The link performance of the serving cell based on Layer 1 measurements and / or predictions is weaker than a specific threshold;

[0416] c. The link performance of candidate cells based on Layer 1 measurements and / or predictions is better than that of the current serving cell (including PCell and SCell) plus the offset;

[0417] d. The link performance of candidate cells based on Layer 1 measurements and / or predictions is better than a specific threshold;

[0418] e. The link performance of the serving cell based on Layer 1 measurement and / or prediction is weaker than a certain threshold, and the link performance of the candidate cell based on Layer 1 measurement and / or prediction is better than a certain threshold.

[0419] f. Interference from candidate cells based on Layer 1 measurements and / or predictions is stronger than a certain threshold for the UE.

[0420] Events a through f are the second events at the cell level.

[0421] For different events, the terminal device may be triggered to perform the same or different behaviors.

[0422] In one example, for the terminal device, the behavior triggered by events a through f is as follows:

[0423] For event a, the UE does not need to report the event, but maintains the measurement of the event;

[0424] For event b, the UE can report the event, including the index of the serving cell and / or the link quality of the serving cell; whereby the NW can subsequently instruct the UE to hand over to a candidate cell (for cell handover, the candidate cell can also be referred to as the target cell);

[0425] For event c, the UE can report the event, including the index of the candidate cell, and / or the link quality of the candidate cell, and / or the index of the serving cell, and / or the link quality of the serving cell; whereby the NW can subsequently instruct the UE to switch to the candidate cell;

[0426] For event d, the UE can report the event, including the index of the candidate cell and / or the link quality of the candidate cell, whereby the NW can subsequently instruct the UE to switch to the candidate cell;

[0427] For event e, the UE can report the event, including the index of the candidate cell, and / or the link quality of the candidate cell, and / or the index of the serving cell, and / or the link quality of the serving cell; wherein, the NW can subsequently instruct the UE to hand over to the candidate cell;

[0428] For event f, the UE can report the event, including the index of the candidate cell and / or the intensity of interference of the candidate cell to the UE's serving cell. The NW can then adjust the transmit power of the beam used by the candidate cell to reduce interference or avoid using the interference beam and scheduling the interfered UE simultaneously.

[0429] Beam-level prediction of mobility events is defined as follows:

[0430] 1. The performance of the serving beam of the serving cell based on Layer 1 measurement and / or prediction is better than a specific threshold;

[0431] 2. The performance of the serving beam of the serving cell based on Layer 1 measurement and / or prediction is weaker than a certain threshold.

[0432] 3. The performance of the candidate beams of the candidate cells based on Layer 1 measurements and / or predictions is better than the performance of the serving beams of the current serving cells (including PCell and SCell) plus the offset.

[0433] IV. The performance of candidate beams for candidate cells based on Layer 1 measurements and / or predictions is better than a specific threshold;

[0434] 5. The performance of the serving beam of the serving cell based on Layer 1 measurement and / or prediction is weaker than a certain threshold, and the performance of the candidate beam of the candidate cell based on Layer 1 measurement and / or prediction is better than a certain threshold.

[0435] 6. Interference from candidate beams of candidate cells based on Layer 1 measurements and / or predictions is stronger than a certain threshold for the UE.

[0436] Events one through six belong to the second event of the beam class.

[0437] In one example, for the terminal device, the behavior triggered by each of events one through six is ​​as follows:

[0438] For event one, the UE does not need to report the event, but should maintain measurement of the event;

[0439] For event two, the UE can report the event, including the index of the serving cell, and / or the link quality of the serving cell, and / or the index of the serving beam, and / or the link quality of the serving beam. The NW can then instruct the UE to switch the current serving beam to another beam (which can come from the current serving cell or a candidate cell).

[0440] For event three, the UE can report the event, including the index of the candidate cell, and / or the link quality of the candidate cell, and / or the index of the candidate beam, and / or the link quality of the candidate beam; and / or the index of the serving cell, and / or the link quality of the serving cell, and / or the index of the serving beam, and / or the link quality of the serving beam. The NW can then instruct the UE to switch the current serving beam to another beam (which can come from the current serving cell or a candidate cell).

[0441] For event four, the UE can report the event, including the index of the candidate cell, and / or the link quality of the candidate cell, and / or the index of the candidate beam, and / or the link quality of the candidate beam, wherein the NW can subsequently instruct the UE to switch to the candidate beam in the candidate cell;

[0442] For event five, the UE can report the event, including the index of the candidate cell, and / or the link quality of the candidate cell, and / or the index of the candidate beam, and / or the link quality of the candidate beam; and / or the index of the serving cell, and / or the link quality of the serving cell, and / or the index of the serving beam, and / or the link quality of the serving beam. The NW can then instruct the UE to switch the current serving beam to another beam (which can come from the current serving cell or a candidate cell).

[0443] For event six, the UE can report the event, including the index of the candidate cell, and / or the candidate beam, and / or the intensity of interference of the candidate beam to the UE's serving beam. The NW can then adjust the transmit power of the beam used by the candidate cell to reduce interference or avoid using the interfering beam and scheduling the interfered UE simultaneously.

[0444] It should be noted that in some embodiments, the metric for measuring the performance of a cell-level or beam-level system is L1-RSRP. In other embodiments, it can also be L1-RSRQ, L1-RSSI, L1-SINR, SNR, or a combination of multiple metrics.

[0445] The UE compares the preset mobility events with the model's prediction results to determine whether a Layer 1 / Layer 2 mobility event has occurred.

[0446] The wireless communication methods provided in this application include, but are not limited to, the following Embodiment 1 and Embodiment 2.

[0447] Example 1: Mobility Event Prediction Based on Model Deployment on the UE Side

[0448] If the model is deployed on a UE, the wireless communication method provided in this application embodiment, as shown in FIG19, includes S1901 to S1905.

[0449] S1901, UE reports its capabilities.

[0450] The UE reports its supported mobility event measurement and prediction capabilities (including cell-level and beam-level). Specifically, the UE first informs the NW whether it supports spatial domain measurement and / or prediction of mobility events. If the UE capability supports this, the UE needs to continue reporting one or more of the following information for the NW to perform subsequent configuration. UE capabilities include, but are not limited to:

[0451] Information 1: On a single carrier, what type of mobility event prediction does the UE-side model support?

[0452] Information 2: On a single carrier, how many candidate cells can the UE support for measurement at most?

[0453] In some embodiments, one candidate cell corresponds to one measurement set; in other embodiments, multiple candidate cells correspond to one measurement set, that is, downlink reference signal resources from multiple candidate cells (including the serving cell) are configured into one measurement set.

[0454] In some embodiments, the UE supports a maximum number of measurement sets on a single carrier. Within each measurement set, the UE can measure a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources).

[0455] Information 3: On a single carrier, the UE can support a maximum number of prediction sets.

[0456] In some embodiments, one candidate cell corresponds to one prediction set; in other embodiments, multiple candidate cells correspond to one prediction set.

[0457] Within each prediction set, the maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources) to predict.

[0458] S1902 and NW configure measurement and prediction resources.

[0459] Based on the UE's capability report, the NW configures resources for the UE, including but not limited to the following resources:

[0460] NW configures the measurement set Set B for candidate cells (including serving cells) for the UE. n (1 <= n <= N) and prediction set Set A m (1 <= m <= M).

[0461] In one example, as shown in Figure 20, the UE's serving cell is cell #1, and candidate cells include cell #2 and cell #3. The NW configures the UE with one or more LTM event types that can be predicted, such as cell-level LTM events A, B, C, etc. Specifically, the measurement set and prediction set for cell #1 are identified as SetB1 and SetA1, respectively, with SetB1 being a subset of SetA1; the measurement set and prediction set for cell #2 are identified as SetB2 and SetA2, respectively, with SetB2 being a subset of SetA2; and the measurement set and prediction set for cell #3 are identified as SetB3 and SetA3, respectively, with SetB3 being a subset of SetA3.

[0462] Additionally, the NW may optionally configure some uplink resources (PUSCH or PUCCH) for the UE. These uplink resources are used to carry the reporting of model-predicted events when a reporting event occurs. In some embodiments, the NW configures PUCCH resources for the UE to request uplink resources, such as for carrying scheduling requests (SRs).

[0463] In some embodiments, for cell-level mobility events, one candidate cell corresponds to one measurement set Set B. n (1 <= n <= N), where N is the total number of candidate cell measurement sets. Each measurement set contains one or more downlink measurement resources for that candidate cell (including the serving cell), i.e., CSI-RS resources and / or SSB resources. Additionally, the prediction set Set A... m (1<=m<=M) can also contain one or more downlink measurement resources.

[0464] In this application embodiment, we consider mobility event prediction in the spatial domain. In some embodiments, a candidate cell may correspond to a measurement set and a prediction set. Set B n It can be Set A m A subset of. For example, Set A m There are a total of 64 transmit beams, but in order to reduce measurement overhead and latency, Set B... n It has only 8 transmit beams.

[0465] In other embodiments, Set B n With Set A m They can also be different, for example, Set B n It includes a small number of SSB-based wide beams, while Set A m The middle one is a narrow beam based on CSI-RS (there are many of them).

[0466] In other embodiments, a candidate cell may correspond to only one prediction set, but without a corresponding measurement set. The model can infer the cell-level and / or beam-level link quality of the candidate cell (which has no corresponding measurement set), as well as LTM mobility events, by using measurements of other candidate cells as input.

[0467] The configuration signaling used by NW can be RRC signaling.

[0468] S1903, UE infers mobility events through the model.

[0469] Once the UE completes the measurement, i.e., measurement set Set B n The measurement results (1<=n<=N) are used as input to the model, and the model makes inferences.

[0470] The prediction result includes one or more of the following inferences. This inference result should be derived from the prediction set Set A. m Choose from (1 <= m <= M).

[0471] Whether a mobility event configured, indicated, or preset by the NW occurs.

[0472] If a mobility event occurs, what type of mobility event (i.e., event type) and other important event information should be included:

[0473] The serving cell information and / or serving beam information and / or serving beam link quality corresponding to the event;

[0474] The candidate cell information corresponding to the event, and / or candidate beam information, and / or candidate beam link quality.

[0475] The relationship between the input and output of model 2101 is shown in Figure 21. The input of model 2101 includes the measurement results corresponding to each set from set B1 to set BN. The output of the model includes the LTM event type, candidate cell information, and serving cell information. The candidate cell information includes the cell index and / or resource (beam) index and / or cell-level link quality and / or beam-level link quality. The serving cell information includes the cell index and / or resource (beam) index and / or cell-level link quality and / or beam-level link quality. Model 2101 is an AI or ML model for LTM event prediction. The candidate cells or serving cells output by model 2101 are the cells corresponding to set Am.

[0476] It should be noted that the model in the embodiments of this application may be a DNN, CNN, RNN, or other similar model.

[0477] For example, for cell-level mobility event prediction, the model outputs one or more of the following information:

[0478] ●Event type c

[0479] ● Index of candidate cells (better than the current serving cell plus an offset)

[0480] ● Link quality of candidate cells (cell level)

[0481] ●Current serving cell link quality (cell level)

[0482] For example, for beam-level mobility event prediction, the model outputs one or more of the following information.

[0483] Event Type Five

[0484] • Index of candidate cells

[0485] • Candidate beam index of candidate cells (represented by the resource index of the reference signal in the following row)

[0486] • Link quality of candidate cells (beam level)

[0487] • Index of service cells

[0488] • Serving beam index of the serving cell (represented by the resource index of the reference signal in the following row)

[0489] • Link quality of the serving cell under the serving beam (beam level)

[0490] S1904, the UE reports a mobility event.

[0491] In some embodiments, the UE can decide whether to report the prediction results of mobility events based on the AI / ML model predictions. For example, if the model predicts that the UE's current serving cell is better than a specific threshold (event A) and still maintains an appropriate link state of the serving cell, then the UE does not need to report or trigger subsequent LTM mobility operations.

[0492] In other embodiments, the UE reports the prediction results of mobility events based on the NW's configuration or indications or predefined rules in the protocol. For example, if the model outputs an optimal cell that is a candidate cell (different from the serving cell) and its performance is better than the current serving cell plus an offset (e.g., 6 dB), the UE can determine that event C has occurred and report it. This offset is generally configured in advance by the NW or predefined in the protocol.

[0493] For predicted mobility event reporting, the UE can report according to the model output. The reported content can include at least one of the following information:

[0494] Predict the types of mobility events that will occur;

[0495] The serving cell information corresponding to the event; wherein, the serving cell information may include: serving cell index, and / or serving beam information, and / or serving beam link quality;

[0496] The candidate cell information corresponding to the event; wherein, the candidate cell information may include: candidate cell index, and / or candidate beam information, and / or candidate beam link quality.

[0497] For predictive mobility event reporting, the UE can use physical layer or higher-level control signaling to carry it. In some embodiments, the UE decides to report when the model infers that a pre-set mobility event has occurred. This reporting resource is such as the periodic PUCCH. This resource is pre-configured to the UE by the NW and does not require the UE to request the resource.

[0498] In other embodiments, the process can be described as follows:

[0499] 1. The output of the UE-side model triggers mobility events (such as the link quality of the candidate cell being better than that of the current serving cell, for example, greater than a certain offset, such as 6dB of L1-RSRP).

[0500] 2. The UE requests resources for reporting mobility prediction events, such as by sending a special scheduling request (SI) to the NW for the purpose of AI / ML prediction;

[0501] 3. NW agrees to the UE's reporting request, sends uplink scheduling DCI, and allocates uplink resources to the UE;

[0502] 4. The UE uses the PUSCH scheduled by NW to carry this mobility-related report.

[0503] In some other embodiments, the reporting of the mobility event may be included in the MAC CE at the MAC layer, or in mobility-related signaling at a higher layer (such as the RRC layer).

[0504] S1905, NW indicates mobility information to the UE.

[0505] Here, mobility information can be understood as third-party information. According to the Cell Switch Command (CSC), the NW can instruct the UE to issue this command. This command itself has a MAC CE bearer, which contains a TCI state ID and a candidate cell index, used to indicate a candidate beam and a candidate cell, respectively. After receiving the cell switch command, the UE completes the cell switch operation within a certain time.

[0506] For mobility events based on AI / ML predictions in this application embodiment, it is highly likely that the candidate beams and / or candidate cells predicted by the model are ones that the UE has not previously measured. In this case, an additional set of measurement resources (such as a set of CSI-RS resources and / or SSB resources) can be specified in the cell handover command, allowing the UE to complete the measurement and / or reporting of the target cell and / or target beam using the specified resources. B1

[0507] For example, a UE can perform downlink synchronization and adjust downlink receive spatial filters (beams) by measuring the SSB resources of a target cell. A UE can also perform time and frequency tracking by measuring the CSI-RS (Tracking RS) of a target cell, or obtain the CSI information of that cell in advance and feed it back to the NW.

[0508] Example 2: Mobility Event Prediction Based on Model Deployment on the NW Side

[0509] If the model is deployed on an NW test site, the wireless communication method provided in this application embodiment, as shown in Figure 22, includes S2201 to S2205.

[0510] S2201, UE reports its capabilities.

[0511] The UE reports its capabilities for measuring and predicting mobility events (including cell-level and beam-level) that it supports. Specifically, the UE first informs the NW whether it supports spatial domain measurement of mobility events. If the UE's capabilities support this, the UE needs to continue reporting one or more of the following information for the NW to perform subsequent configuration. UE capabilities include, but are not limited to:

[0512] Information 1: On a single carrier, the UE can support a maximum number of candidate cells for measurement;

[0513] In some embodiments, one candidate cell corresponds to one measurement set; in other embodiments, multiple candidate cells correspond to one measurement set, that is, downlink reference signal resources from multiple candidate cells (including the serving cell) are configured into one measurement set.

[0514] In some embodiments, the UE supports a maximum number of measurement sets on a single carrier. Within each measurement set, the UE can measure a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources).

[0515] It should be noted that because the model is deployed on the NW side, the UE does not need to report its ability to predict mobility events.

[0516] S2202 and NW configure measurement resources.

[0517] Based on the UE's capability report, the NW configures resources for the UE, including but not limited to the following resources:

[0518] Resource 1: NW configures the measurement set Set B for candidate cells (including serving cells) for the UE. n (1 <= n <= N).

[0519] Additionally, the NW can optionally configure some uplink resources (PUSCH or PUCCH) for the UE. When the UE completes the Set B... n After a measurement of (1 <= n <= N), this uplink resource is used to carry the reporting of the measurement results. Set B n (1<=n<=N) includes downlink measurement resources for candidate cells and serving cells.

[0520] In some embodiments, for cell-level mobility events, one candidate cell corresponds to one measurement set Set B.n (1 <= n <= N), where N is the total number of candidate cell measurement sets. Each measurement set contains one or more downlink measurement resources for the candidate cell (including the serving cell), namely CSI-RS resources and / or SSB resources.

[0521] The configuration signaling used by NW can be RRC signaling.

[0522] It should be noted that because the model is deployed on the NW, the NW does not need to configure a prediction set of mobility events for the UE.

[0523] S2203, UE performs measurement and reporting of measurement results.

[0524] According to the NW configuration, the UE measures the resource set Set Bn (1<=n<=N) of mobility events. The UE measures and obtains the link quality corresponding to the resources in this set, such as L1-RSRP.

[0525] The UE reports the measurement results to the NW via uplink signaling. In some embodiments, this uplink signaling is reported in the physical layer's UCI in the form of beam reporting. This UCI can be carried via PUCCH or PUSCH. It is important to emphasize that, because Set B n (1<=n<=N) includes the serving cell and multiple candidate cells, so the measurement volume is often large. According to the traditional NR method, each report contains a maximum of 4 reference signal resource indices and corresponding link quality (such as L1-RSRP), which is obviously difficult to meet the carrying requirements.

[0526] The embodiments of this application consider enhancing the uplink beam reporting capacity in the following manner.

[0527] The first method, also known as the first transmission method, involves the UE following a pre-configured or arranged measurement set Set B. n The UE reports the results in the following order. For example, the UE first reports the measurement results of the measurement resources in Set B1, then reports the measurement results of the measurement resources in Set B2, and so on, until it reports the results of Set B... N The measurement results for the measured resources. The measurement results include resource indexes and link quality, but do not include Set B. n The index is shown in Table 1. The UE reports measurement results for a total of N measurement sets, assuming each measurement set contains M measurement resources. In some embodiments, the number of resources for each measurement set may differ. Reporting measurement results based on the first method avoids reporting Set B. n The index reduces reporting overhead, allowing more resource indexes and corresponding link quality to be reported.

[0528] Table 1 shows examples of reported measurement results.

[0529] The field CRI or SSBRI#1 indicates the resource index to be reported. You can report only CRI or SSBRI, or both.

[0530] The second method, also known as the second transmission method, involves the UE not only following the pre-configured or arranged measurement set Set B n The order of reporting is also based on the ranking of resources in each measurement set, as shown in Table 2. For Set B n RSRP is reported according to the resource allocation information. For example, in Set B... n There are a total of 16 resources. The link quality corresponding to the 16 resources can be reported according to a specific resource sorting (such as resource index from high to low or from low to high), which can further save the reporting overhead occupied by resource index.

[0531] Because the measurement resources are configured by NW, the NW side can understand the resource index and measurement set index corresponding to the reported link quality.

[0532] Table 2 shows examples of reported measurement results.

[0533] The third method, also known as the third transmission method, differs from the first and second methods (which increase the capacity of reported content by reducing the amount of reported content). It considers concatenating the content of multiple reporting instances, such as beam reporting instance #1, beam reporting instance #3, and beam reporting instance #6, to form a complete report.

[0534] This is possible only if the UE informs the NW in the reported content which beam reporting instances it used in sequence to report the complete measurement set Set B. n (1 <= n <= N). In other embodiments, the NW can also inform the UE, through pre-configuration or indication, which (more than one) beam reporting instances to use to report the complete measurement set Set B. n (1 <= n <= N).

[0535] It should be noted that the third reporting method can also be used in combination with the first or second reporting method.

[0536] In other embodiments, the uplink signaling may be MAC CE or RRC signaling.

[0537] S2204 and NW infer mobility events through models.

[0538] The NW-side model makes similar inferences to the UE-side model; see the description in S1904 for details.

[0539] S2205, NW indicates mobility information to the UE.

[0540] The description of S2205 is consistent with that of S1905, and will not be repeated here.
