[0064] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0065] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.
[0066] As shown in Figure 1, a communication system 100 may include a terminal device 110 and a network device 120. The network device 120 may communicate with the terminal device 110 via an air interface. The terminal device 110 and the network device 120 support multi-service transmission.
[0067] It should be understood that the embodiments of the present application are only illustrative of the communication system 100, but the embodiments of the present application are not limited thereto. That is, the technical solutions of the embodiments of the present 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.
[0068] In the communication system 100 shown in Figure 1, the network device 120 may be an access network device that communicates with the terminal device 110. The access network device may provide communication coverage for a specific geographical area and may communicate with the terminal device 110 (e.g., user equipment (UE)) located within the coverage area.
[0069] The network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, or a Next Generation Radio Access Network (NG RAN) device, or a base station (gNB) in an NR system, or a wireless controller in a Cloud Radio Access Network (CRAN), or the network device 120 may be a relay station, an access point, an in-vehicle device, a wearable device, a hub, a switch, a bridge, a router, or a network device in a future evolved Public Land Mobile Network (PLMN), etc.
[0070] The terminal device 110 may be any terminal device, including but not limited to a terminal device connected to the network device 120 or other terminal devices by wire or wireless connection.
[0071] For example, the terminal device 110 may 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 may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, an IoT device, a satellite handheld terminal, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolution network, etc.
[0072] The 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 for communicating with the base station. The 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 of 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 that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.
[0074] The functional units in the communication system 100 may also establish connections and implement communication via next generation (NG) network interfaces.
[0075] For example, the terminal device establishes an air interface connection with the access network device through the Uu interface for transmitting user plane data and control plane signaling; the terminal device can establish a control plane signaling connection with the AMF through the NG interface 1 (referred to as N1); the access network device, such as the next generation wireless access base station (gNB), can establish a user plane data connection with the UPF through the NG interface 3 (referred to as N3); the access network device can establish a control plane signaling connection with the AMF through the NG interface 2 (referred to as N2); the UPF can establish a control plane signaling connection with the SMF through the NG interface 4 (referred to as N4); the UPF can exchange user plane data with the data network through the NG interface 6 (referred to as N6); the AMF can establish a control plane signaling connection with the SMF through the NG interface 11 (referred to as N11); the SMF can establish a control plane signaling connection with the PCF through the NG interface 7 (referred to as N7).
[0076] Figure 1 exemplarily shows 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, which is not limited in this embodiment of the present application.
[0077] It should be noted that Figure 1 is merely an example of a system applicable to this application. Of course, the methods described in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably herein. The term "and / or" herein simply describes an association relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the associated objects are in an "or" relationship. It should also be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, "A indicates B" can mean that A directly indicates B, for example, B can obtain information through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can obtain information through C; or it can mean that A and B have an association relationship. It should also be understood that the "correspondence" mentioned in the embodiments of this application can mean that there is a direct or indirect correspondence between two objects, or that there is an association relationship between the two objects, or a relationship between an indicator and the indicated, a configuration and the configured, and so on. It should also be understood that the “predefined” or “predefined rules” mentioned in the embodiments of the present application can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and the present application does not limit its specific implementation method. For example, predefined can refer to a definition in a protocol. It should also be understood that in the embodiments of the present application, the “protocol” can refer to a standard protocol in the field of communications, such as an LTE protocol, an NR protocol, and related protocols used in future communication systems, and the present application does not limit this.
[0078] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
[0079] Layer 1 / Layer 2 Triggered Mobility (LTM)
[0080] The NR system only supports Layer 3 (i.e., Radio Resource Control (RRC) layer) mobility in Release (R) 15 to R17. Starting from R18, NR standardizes the enhancement of LTM. From the physical layer (i.e., Layer 1 (L1)), the UE pre-measures multiple candidate cells (including the current serving cell) through the downlink measurement resources configured by the network (NW), and then reports the measurement results to the NW, i.e., the network device. The NW indicates the selected candidate cell (i.e., target cell) and / or selected beam through the cell handover command.
[0081] For measurement and reporting, the UE can measure multiple candidate cells configured by the NW (including the current serving cell) and provide up to M x L measurement results in a single report (depending on UE capabilities, where L is the number of candidate cells and M is the number of beams per cell). Obviously, measuring a large number of candidate cells requires a lot of reference signal overhead and the latency required for the UE to measure these reference signals. After all, the UE often cannot measure multiple beams of multiple candidate cells simultaneously.
[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 target cell information (such as candidate cell index) and / or selected beam information (i.e., indicated by one or more Unified Transmission Configuration Indication (TCI) state identifiers (Identity document, ID)).
[0083] Artificial Intelligence (AI) / Machine Learning (ML) Models
[0084] A neural network is a computational model consisting of multiple interconnected neuron nodes. The connections between nodes represent weighted values, called weights, from input signals to output signals. Each node performs a weighted summation of different input signals and outputs them through a specific activation function. Figure 2 shows the neuron structure. Weights w1 through wn, b are used to perform a weighted summation of a1 through an, 1, respectively. The result of this weighted summation is then passed through an activation function f to produce the output t.
[0085] A simple neural network, shown in Figure 3, consists of an input layer 301, a hidden layer 302, and an output layer 303. By using different connections, weights, and activation functions among multiple neurons, different outputs can be generated, thereby fitting the mapping relationship from input to output. Each node in the previous level is connected to all nodes in the next level. This fully connected model is also called a deep neural network (DNN). This neural network (NN) model can perform beam prediction in the spatial domain.
[0086] A NN model can be trained and obtained through the process of dataset construction, training, verification, and testing. It is assumed that the NN model has already been trained in advance through offline or online training. It should be noted that offline and online training are not mutually exclusive. First, the NW can obtain a static training result through offline training of the dataset, which can be referred to as offline training. As the NW or UE uses the NN, as the UE further measures and / or reports, the NN model can continue to collect more data, performing real-time online training to optimize the NN model parameters and achieve better inference and prediction results.
[0087] It should be noted that beam can refer to either a transmit beam or a receive beam. In the protocol, the term transmit / receive spatial filter is generally used to replace the implementation-oriented term transmit / receive beam. In the embodiments of the present application, beam and spatial filter are interchangeable.
[0088] For a model, its output can be understood as inference or prediction, where inference and prediction have the same meaning and can be used interchangeably.
[0089] For LTM in Release 18, the UE is responsible for performing numerous downlink measurements and reporting the results to the network network (NW). Since Release 18 does not define reporting of event-triggered mobility events, the UE is forced to perform downlink multi-cell and / or multi-beam measurements and report these measurements to the network network, lacking reporting autonomy and selectivity.
[0090] Assuming 3GPP defines LTM mobility events in subsequent releases, the UE will also need to perform extensive measurements to determine whether the conditions for triggering mobility events are met. These measurements themselves will consume significant measurement resources and UE measurement overhead, such as the time and frequency resources used by beam scanning. Furthermore, during these extensive measurements, the UE may require measurement gap protection, temporarily suspending downlink reception and uplink transmission in the cell, impacting normal communications.
[0091] Therefore, using AI / ML technology to predict whether an LTM event occurs and related information of the LTM event can be used as a technical path to solve the LTM problem.
[0092] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0093] The wireless communication method provided in the embodiment of the present application is applied to a terminal device, as shown in FIG4 , and includes:
[0094] S401. The terminal device predicts first prediction information based on one or more first measurement results, where the first prediction information is related to the one or more first prediction results. The first measurement result is a measurement result obtained by measuring a first cell, and the first prediction result is a measurement result 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 a measurement result 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] It is understandable that, 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 first cell, the terminal device measures the first cell using one or more measurement resources of the first cell. It can be understood that one measurement resource corresponds to one spatial filter.
[0098] The first measurement result in the embodiment of the present application may be a measurement result obtained by performing layer 1 measurement on the first cell, and the first measurement result may include: L1-reference signal received power (Reference Signal Receiving Power, RSRP), L1-reference signal received quality (Reference Signal Receiving Power, RSRQ), L1-received signal strength indication (Received Signal Strength Indication, RSSI), L1-signal to interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), signal-to-noise ratio (Signal-to-Noise Ratio, SNR) One or more.
[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 the first number of first measurement results, the terminal device predicts first prediction information based on the first number of first measurement results. The first prediction information is related to the first prediction result. It is understandable that the first prediction information is determined based on the first prediction result.
[0101] The first prediction result is a measurement result of the second cell predicted based on the first number of first measurement results. The first number of first measurement results may predict one or more first prediction results, with different first prediction results in the multiple first prediction results corresponding to different second cells. It is understood that the first prediction result is the measurement result of the second cell, but the first prediction result is not a measurement result obtained by measuring the second cell, but rather a measurement result predicted or inferred based on the first number of first measurement results.
[0102] It is understandable that the second cell belongs to the first number of first cells or does not belong to the first number of first cells.
[0103] In one example, the terminal device obtains first prediction information related to the prediction results of cell 4 and cell 5 based on the measurement results of cell 1, cell 2 and cell 3, wherein the prediction results of cell 4 and cell 5 are predicted based on the measurement results of cell 1, cell 2 and cell 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 in various forms, such as a function, a deep learning model, a neural network model (e.g., a DNN, a CNN, or a RNN). The terminal device inputs a first number of first measurement results into the first prediction model to obtain first prediction information output by the first prediction model.
[0106] In the wireless communication method provided in an embodiment of the present application, a terminal 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 predicting the measurement results of one or more second cells when measuring the one or more first cells, and obtains the first prediction information based on the predicted measurement results of the one or more second cells, thereby obtaining the first prediction information without the need to measure the one or more second cells, thereby reducing the overhead of the reference signal used for cell measurement.
[0107] In some embodiments, based on FIG4 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG5 , including:
[0108] S501. The terminal device sends second information to a network device, where the second information is used to indicate a second mobility event, where the second mobility event is the first mobility event that triggers reporting, and where the first mobility event is related to a first prediction result.
[0109] The first prediction information includes a first mobility event, which is a mobility event related to the first prediction result. The mobility event can be understood as an event related to the mobility of the terminal device.
[0110] In some embodiments, an embodiment of the present application provides a wireless communication method, applied to a network device, as shown in FIG6 , including:
[0111] S601. A network device receives second information sent by a terminal device, where the second information is used to indicate a second mobility event, where the second mobility event is a reported first mobility event, where the first mobility event is related to a first prediction result, where the first prediction result is a measurement result of a second cell predicted based on one or more first measurement results, where the first measurement result is a measurement result obtained by measuring the first cell.
[0112] The one or more first measurement results are used to predict first prediction information, and the first prediction information is related to the one or more first prediction results.
[0113] The wireless communication method shown in FIG. 5 or FIG. 6 is further described below.
[0114] The terminal device determines, based on the first prediction result, that a first mobility event has occurred on the terminal device, and the occurrence of the first mobility event triggers reporting. The terminal device then needs to report the reported first mobility event to the network device. At this point, the terminal device sends second information to the network device, where the second information is used to indicate that the reported first mobility event is the second mobility event.
[0115] The network device receives the second information sent by the terminal device, and determines, based on the second information, that a second mobility event has occurred in the terminal device.
[0116] It is understandable that the terminal device may determine one or more first mobility events based on the first prediction result, and all or part of the one or more first mobility events determined are second mobility events.
[0117] In an embodiment of the present application, if the terminal device predicts a second mobility event based on one or more first measurement results, the second mobility event can be reported directly to the network device without reporting the first measurement result 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, where the first indication information is used to indicate whether one or more first mobility events occur, where the first mobility events are related to the first prediction result;
[0120] second indication information, where the second indication information is used to indicate an event type of the first mobility event that occurred;
[0121] First information, where the first information indicates a first prediction result corresponding to the first mobility event that occurs.
[0122] In the embodiment of the present application, the first indication information may be used to indicate whether one or more first mobility events occur in the terminal device.
[0123] It can be understood that 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 event configured or preset by the network device occurs.
[0125] If a first mobility event occurs, the second indication information is used to indicate which first mobility event has occurred. It is understandable that if multiple first mobility events occur, the first prediction information includes multiple second indication information, and different second indication information indicates the event type of different first mobility events.
[0126] The first information is used to indicate a first prediction result corresponding to a 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] The first event A and the one or more second cells corresponding to the one or more first mobility events include a serving cell, and a link performance of the serving cell measured and / or predicted based on layer 1 is better than a first threshold;
[0129] First event B: the one or more second cells include a serving cell, and the link performance of the second cell, which is a serving cell measured and / or predicted based on layer 1, is weaker than a second threshold;
[0130] First event C: the one or more second cells include a candidate cell and a serving cell, and a link performance of the candidate cell measured and / or predicted based on layer 1 is better than a first link performance, where the first link performance is the link performance of the serving cell plus a first offset;
[0131] First event D: the one or more second cells include a candidate cell, and the link performance of the candidate cell measured and / or predicted based on layer 1 is better than a third threshold;
[0132] First event E: the one or more second cells include a candidate cell and a serving cell, the link performance of the serving cell based on layer 1 measurement and / or prediction is weaker than a fourth threshold, and the link performance of the candidate cell based on layer 1 measurement and / or prediction is better than a fifth threshold;
[0133] First event F: the one or more second cells include a candidate cell, and interference of the candidate cell measured and / or predicted based on layer one is stronger than a first interference threshold.
[0134] It can be understood that 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 one or more first mobility events predicted by the terminal device based on the one or more first measurement results include one or more of first events A to F.
[0136] For the threshold values such as the first threshold to the fifth threshold and the first interference threshold involved in the first event A to the first event F, the values of different threshold values may be the same or different.
[0137] In the embodiment of the present application, the link performance of the cell can be represented by one or more parameters of the cell's L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR that characterize the link quality of the cell.
[0138] It is understandable that if the second cell has a first measurement result and a first prediction result, the terminal device may determine whether the first mobility event has occurred in the second cell based on the first measurement result and / or the first prediction result of the second cell. Optionally, the terminal device determines whether the first mobility event has occurred in the second cell based on the first measurement result of the second cell. Optionally, the terminal device determines whether the first mobility event has occurred in the second cell based on the first prediction result of the second cell. Optionally, the terminal device determines whether the first mobility event has occurred in the second cell based on the result with better link performance between the first measurement result and the first prediction result of the second cell.
[0139] In some embodiments, the one or more first mobility events include one or more of the following second events:
[0140] Second event A: the one or more second cells corresponding to the one or more first mobility events include a serving cell, and performance of a serving spatial filter of the serving cell measured and / or predicted based on layer one is better than a sixth threshold;
[0141] Second event B: the one or more second cells include a serving cell, and performance of a serving spatial filter of the serving cell measured and / or predicted based on layer one is weaker than a seventh threshold;
[0142] Second event C: the one or more second cells include a candidate cell and a serving cell, and performance of a candidate spatial filter of the candidate cell measured and / or predicted based on layer one is better than a second link performance, where the second link performance is the performance of the serving spatial filter of the serving cell plus a second offset;
[0143] A second event D: the one or more second cells include a candidate cell, and performance of a candidate spatial filter of the candidate cell measured and / or predicted based on layer one is better than an eighth threshold;
[0144] Second event E: the one or more second cells include a candidate cell, performance of a serving spatial filter of the serving cell based on layer one measurement and / or prediction is weaker than a ninth threshold, and performance of a candidate spatial filter of the candidate cell based on layer one measurement and / or prediction is better than a tenth threshold;
[0145] Second event F: the one or more second cells include a candidate cell, and interference of a candidate beam of the candidate cell measured and / or predicted based on layer one is stronger than a second interference threshold.
[0146] In the embodiment of the present application, the second event is a beam-level, ie, spatial filter-level, mobility event related to the performance of the serving spatial filter and / or the performance of the candidate spatial filters.
[0147] It can be understood that the spatial filter of the serving cell is divided into a serving spatial filter and a candidate spatial filter, and the spatial filter of the candidate cell is the candidate spatial filter.
[0148] The one or more first mobility events predicted by the terminal device based on the one or more first measurement results include one or more of second events A to F.
[0149] For the threshold values such as the sixth threshold to the tenth threshold and the second interference threshold involved in the second event A to the second event F, the values of different threshold values may be the same or different.
[0150] In an embodiment of the present application, the performance of the spatial filter may be represented by one or more parameters of the spatial filter, including L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR, which characterize the link quality of the spatial filter.
[0151] In the embodiment of the present application, the first mobility event determined by the terminal device based on one or more first measurement results may 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, the multiple first mobility events may all be cell-level mobility events, or all may be spatial filter-level mobility events, or some may be cell-level mobility events and some may be beam-level mobility events.
[0153] In one example, if a first event A occurs, the first prediction information includes at least one of the following information:
[0154] First indication information whose value is a first value, wherein the first indication information whose value is the first value indicates that a first mobility event has occurred;
[0155] The event type of the first event A;
[0156] The first information corresponding to the first event A.
[0157] In one example, if a first event A and a second event B occur, the first prediction information includes at least one of the following information:
[0158] First indication information having a first value;
[0159] The event type of the first event A and the event type of the second event B;
[0160] The first information corresponding to the first event A and the first information corresponding to the second event B.
[0161] In one example, if the first mobility event does not occur, the first prediction information includes at least one of the following information:
[0162] The first indication information whose value is the second value indicates that the first mobility event has not occurred.
[0163] In some embodiments, the first information includes one or more of the following:
[0164] cell index and / or cell link quality;
[0165] Cell link quality and / or spatial filter link quality.
[0166] It is understandable that the first mobility event includes a cell-level first mobility event, and the first information corresponding to the first mobility event includes cell information corresponding to the first mobility event, and the cell information includes: cell index and / or cell link quality.
[0167] If the first cell-level mobility event is related to the serving cell, the first information includes an index of the serving cell and a link quality of the serving cell. In one example, if the first mobility event includes a first event A, the first information includes an index of the serving cell and / or a link quality of the serving cell.
[0168] If the first cell-level mobility event is related to a candidate cell, the first information includes an index of the candidate cell and a link quality of the candidate cell. In one example, if the first mobility event includes a first event D, the first information includes an index of the candidate cell and / or a link quality of the candidate cell.
[0169] If the first cell-level mobility event occurs and is related to a serving cell and a candidate cell, the first information includes an index of the serving cell and / or a link quality of the serving cell, and an index of the candidate cell and / or a link quality of the candidate cell. In one example, if the first mobility event occurs and includes a first event A and a first event D, the first information includes: an index of the serving cell and / or a link quality of the serving cell; an index of the candidate cell and / or a link quality of the candidate cell.
[0170] It can be understood that the first mobility event that occurs includes the first mobility event of the spatial filter level, and the first information corresponding to the first mobility event includes the cell information and / or spatial filter information corresponding to the first mobility event, and 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 of the spatial filter level is related to the serving spatial filter, 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 an example, if the first mobility event includes the second event A, the first information includes an index of the serving spatial filter and / or a link quality of the serving spatial filter.
[0173] In an example, if the first mobility event includes the second event A, the first information includes an index of the serving cell and / or a link quality of the serving cell.
[0174] In one example, if the first mobility event includes the second event A, the first information includes an index of a serving cell and / or a link quality of the serving cell, and an index of a serving spatial filter and / or a link quality of the serving spatial filter.
[0175] If the first mobility event of the spatial filter level is related to the candidate spatial filter, 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 an example, if the first mobility event includes the second event D, the first information includes: an index of the candidate spatial filter and / or a link quality of the candidate spatial filter.
[0177] In an example, if the first mobility event includes the second event D, the first information includes: an index of the candidate cell and / or a link quality of the candidate cell.
[0178] In one example, if the first mobility event includes the second event D, the first information includes: an index of a candidate cell and / or a link quality of the candidate cell, and an index of a candidate spatial filter and / or a link quality of the candidate spatial filter.
[0179] If the first mobility event at the spatial filter level is related to the serving spatial filter and the candidate spatial filter, the cell information included in the first information includes information about the serving cell and information about the candidate cell, and the spatial filter information included in the first information includes information about the serving spatial filter and information about the candidate spatial filter, that is, the first information includes:
[0180] an index of a serving cell and / or a link quality of the serving cell, and / or an index of a serving spatial filter and / or a link quality of the serving spatial filter;
[0181] and, an index of a candidate cell and / or a link quality of the candidate cell, and / or an index of a candidate spatial filter and / or a link quality of the candidate spatial filter.
[0182] In an embodiment of the present application, if the first mobility event that occurs includes a first mobility event at the cell level and a first mobility event at the spatial filter level, the first information corresponding to the first mobility event at the cell level includes cell information, and the first information corresponding to the first mobility event at the spatial filter level 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 in the first mobility event indicated by the first prediction information, namely the second mobility event, 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 does not send the second information. At this time, the network device does 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 the 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 the second information, and the sent second information indicates the first event B and the second event B.
[0187] In some embodiments, when the terminal device reports a second mobility event, the second mobility event is:
[0188] Determined by the terminal equipment; or
[0189] Indicated by the network device; or
[0190] Predefined.
[0191] If the second mobility event is determined by the terminal device, the terminal device may decide on its own whether to report the first prediction result of the mobility event.
[0192] If the second mobility event is indicated by the network device, the terminal device reports the first prediction result of the mobility event according to the configuration or instruction 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 predefinition 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 and does not need to trigger subsequent LTM mobility operations.
[0195] In one example, when the first prediction information indicates that the 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 layer control element MAC CE of the media access control MAC layer;
[0199] Mobility-related signaling at the Radio Resource Control (RRC) layer.
[0200] In an embodiment of the present application, the terminal device may use control signaling of the physical layer or a higher layer to carry the second information.
[0201] In some embodiments, when the terminal device reports the 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 configured in advance by the network device to the terminal device, and the terminal device does not need to make a resource request.
[0203] In some embodiments, the second information may be included in a MAC CE of the MAC layer, or in mobility-related signaling of a higher layer (such as the RRC layer).
[0204] In some embodiments, for one of the second mobility events, the second information includes one or more of the following information:
[0205] third indication information, where the third indication information is used to indicate an event type of the second mobility event;
[0206] first information corresponding to the second mobility event.
[0207] Here, the description of the first information can refer to the above description and will not be repeated here.
[0208] In some embodiments, based on FIG5 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG7 , including:
[0209] S701. The terminal device receives a cell switching command sent by the network device, where the cell switching command carries third information indicating a target cell, and the third information is related to the second information.
[0210] In some embodiments, based on FIG6 , an embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG8 , including:
[0211] S801. The network device sends a cell switching command to the terminal device, where the cell switching command carries third information indicating a target cell, and the third information is related to the second information.
[0212] After receiving the second information sent by the terminal device, the network device determines third information based on or without the second information in response to the second information, and sends the third information to the terminal device, wherein the third information is used to indicate the target cell.
[0213] Optionally, the network device sends the third information to the terminal device via a cell switch command (Cell Switch Command, CSC).
[0214] Optionally, the cell switching command itself has a MAC CE bearer, which includes a TCI state ID and a candidate cell index (candidate cell index), where 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 the cell switching command from the network device, the terminal device completes the cell switching operation to the target cell within a certain period of time.
[0216] In the embodiment of the present application, the target cell indicated by the third information may belong to the first cell or may not belong to the first cell. It is understandable 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, and the first measurement resource is used for measuring the target cell and / or reporting the measurement result.
[0218] When 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, first measurement resources, and the terminal device may complete the measurement and / or reporting of the target cell and / or target beam through the first measurement resources. The first 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 by measuring the SSB resource in the first measurement resource, and adjust the downlink receiving spatial filter, etc.
[0220] In one example, the terminal device may 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 FIG. 4 , FIG. 5 , or FIG. 7 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 9 , including:
[0222] S901. The terminal device receives first configuration information sent by a network device, where the first configuration information is used to configure one or more first sets and / or one or more second sets, where the one or more first sets include one or more second measurement resources corresponding to the first cells, and the one or more second sets include one or more predicted resources corresponding to third cells, where the second cell is one of the one or more third cells.
[0223] In some embodiments, based on FIG. 6 or FIG. 8 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 10 , including:
[0224] S1001. The network device sends first configuration information to the terminal device, where the first configuration information is used to configure one or more first sets and / or one or more second sets, where the one or more first sets include one or more second measurement resources of the first cells, and the one or more second sets include one or more predicted resources of the third cells, where the second cell is one of the one or more third cells.
[0225] One or more first sets may be labeled as measurement set Set B n (1<=n<=N), one or more first sets, namely Set B 1、 Set B2…Set B N The measurement resources including the first number of first cells are the second measurement resources.
[0226] One or more second sets may be labeled as prediction sets Set A n (1<=n<=M), one or more second sets, namely Set A 1、 Set A2…Set A M The predicted resources of a second number of third cells are included, and the second cell is one of the third cells.
[0227] It is understandable that the second cell corresponding to the first prediction result belongs to the second number of third cells corresponding to one or more second sets, wherein the second cell corresponding to the first prediction information includes some or all of the second number of third cells, that is, the second cell corresponding to the first prediction result should be selected from the prediction set Set A. m Selected from the third cell corresponding to (1<=m<=M).
[0228] In some embodiments, one or more first cells correspond to one first set.
[0229] It can be understood that a first set includes one or more second measurement resources of a first cell, 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 second set.
[0231] It can be understood that a second set includes one or more predicted resources of a third cell, wherein a third cell includes one or more predicted resources, and a predicted resource corresponds to a spatial filter of the third cell.
[0232] In some embodiments, the relationship between the second measurement resources included in the one or more first sets and the prediction resources included in the one or more second sets includes one of the following:
[0233] Relationship 1: The second measurement resources included in the first set and the prediction resources included in the second set do not contain the same resources.
[0234] Relationship 2: One first cell corresponds to one first set and one second set, and the first set is a subset of the second set.
[0235] In relationship one, the second measured resource is different from the predicted resource.
[0236] In one example, the second measurement resource is a wide beam based on SSB (fewer in number), and the prediction resource is a narrow beam based on CSI-RS (more in number).
[0237] In the second relationship, corresponding to the first set and the third set of 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, a first set corresponding to a cell includes 8 measurement resources, ie, corresponding to 8 spatial filters, and a second set corresponding to the cell includes 64 prediction resources, ie, corresponding to 64 beams.
[0239] In the embodiment of the present application, the measurement resources corresponding to a cell are a subset of the prediction resources corresponding to the cell, which can reduce the measurement overhead and delay.
[0240] In some embodiments, one said third cell corresponds to one said second set, and there is no corresponding first set.
[0241] For the third cell, there is no corresponding second measurement resource, so the measurement result of the third cell can only be predicted based on the measurement results of the first cell, that is, other cells.
[0242] In some embodiments, the first configuration information is further used to configure one or more of the following:
[0243] a third mobility event, where 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, the first uplink resource is used to report a second mobility event, the second uplink resource is used to transmit a first request, the first request is used to request the first uplink resource, and the second mobility event is the reported first mobility event included in the first prediction information.
[0245] The third mobility event is a mobility event that can be predicted based on the one or more first measurement results.
[0246] The first uplink resource is a resource used by the terminal device to report the second mobility event. The second uplink resource is a resource used by the terminal device to request the first uplink resource.
[0247] It is understandable that if the first configuration information is configured with a first uplink resource, the terminal device reports the second mobility event based on the first uplink resource configured by the first configuration information. If the first configuration information is not configured with a first uplink resource, the terminal device sends a first request based on the second uplink resource configured by 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 may send uplink scheduling downlink control information (Downlink Control Information, DCI) to the terminal device. The uplink scheduling DCI is used to schedule the first uplink resource.
[0249] In some embodiments, based on FIG. 4 or FIG. 5 or FIG. 7 or FIG. 9 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 11 , including:
[0250] S1101. The terminal device sends fourth information to a network device, where the fourth information is used to indicate one or more of the following capabilities of the terminal device:
[0251] whether the terminal device supports measurement of the one or more first measurement results and / or supports prediction of the first prediction information based on the one or more first measurement results;
[0252] one or more fourth mobility events, where the fourth mobility event is a mobility event predicted by the one or more first measurement results;
[0253] A first quantity, where the first quantity is the number of first cells supported by the terminal device on one carrier;
[0254] a second quantity, where the second quantity is the quantity of first sets supported by the terminal device on one carrier, where one first set includes second measurement resources corresponding to one or more first cells;
[0255] The third quantity is the number of second sets supported by the terminal device on one carrier; the second set is used to configure predicted resources of a third cell; the third cell is the cell corresponding to the predicted result used for prediction by the one or more first measurement results.
[0256] In some embodiments, based on FIG. 6 , FIG. 8 , or FIG. 10 , an embodiment of the present application provides a wireless communication method, applied to a network device, as shown in FIG. 11 , including:
[0257] S1101. The network device receives fourth information sent by the terminal device, where the fourth information is used to indicate one or more of the following capabilities of the terminal device:
[0258] whether the terminal device supports measurement of the one or more first measurement results and / or supports prediction of the first prediction information based on the one or more first measurement results;
[0259] one or more fourth mobility events, where the fourth mobility event is a mobility event supported by the terminal device for prediction;
[0260] A first quantity, where the first quantity is the number of first cells supported by the terminal device on one carrier;
[0261] a second quantity, where the second quantity is the quantity of first sets supported by the terminal device on one carrier, where one first set includes second measurement resources corresponding to one or more first cells;
[0262] The third quantity is the number of second sets supported by the terminal device on one carrier, and the second set is used to configure the predicted resources of the third cell; the third cell is the cell corresponding to the predicted result used for the prediction of the one or more first measurement results.
[0263] In an embodiment of the present application, the terminal device reports the measurement and prediction capabilities supported by the terminal device to the network device based on the fourth information, wherein the measurement and prediction capabilities may include cell level and / or spatial filter level.
[0264] Here, the first mobility event, the second mobility event, the third mobility event, and the fourth mobility event are described:
[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 reported mobility event predicted by the terminal device based on one or more first measurement results;
[0267] The third mobility event is a mobility event that can be predicted by the terminal device configured by the network device based on one or more first measurement results;
[0268] The fourth mobility event is a mobility event that the terminal device supports prediction.
[0269] Optionally, the fourth information includes fifth indication information, and the fifth indication information 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, or the fourth information does not include the fourth indication information. When indicating other content, it is assumed 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.
[0270] In an embodiment of the present application, after receiving the fourth information, the network device may configure the first set and / or the second set based on the fourth information.
[0271] An embodiment of the present application provides a wireless communication method, which is 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, where 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, and the first prediction information is related to the one or more first prediction results, and the first prediction result is a measurement result of a second cell predicted based on the one or more first measurement results.
[0273] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG13 , including:
[0274] S1301. A network device receives one or more first measurement results sent by a terminal device, where the first measurement results are measurement results obtained by measuring a first cell.
[0275] S1302. The network device predicts first prediction information based on the one or more first measurement results, where the first prediction information is related to the one or more first prediction results, and the first prediction result is a 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 a measurement result 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] It is understandable that, 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 first cell, the terminal device measures the first cell using one or more measurement resources of the first cell. It can be understood that one measurement resource corresponds to one spatial filter.
[0279] The first measurement result in the embodiment of the present application may be a 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 of the first cell may be CSI-RS resources and / or SSB resources.
[0281] After the terminal device determines the first number of first measurement results, it reports the first number of first measurement results to the network device, so that the network device predicts the first prediction information based on the first number of first measurement results.
[0282] The first quantity of first measurement results may be reported to the network device via uplink signaling. In some embodiments, the uplink signaling is reported in uplink control information (UCI) of the physical layer in the form of a spatial filter report. The UCI may be carried via a PUCCH or a physical uplink shared channel (PUSCH). The uplink signaling may also be MAC CE or RRC signaling.
[0283] After receiving the 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 result. It is understandable that the first prediction information is determined based on the first prediction result.
[0284] The first prediction result is a measurement result of the second cell predicted based on the first number of first measurement results. The first number of first measurement results may predict one or more first prediction results, with different first prediction results in the multiple first prediction results corresponding to different second cells. It is understood that the first prediction result is the measurement result of the second cell, but the first prediction result is not a measurement result obtained by measuring the second cell, but rather a measurement result predicted or inferred based on the first number of first measurement results.
[0285] It is understandable that the second cell belongs to the first number of first cells or does not belong to the first number of first cells.
[0286] In some embodiments, a second prediction model is deployed in the network device. The second prediction model can be expressed in various models, such as a function, a deep learning model, a neural network model, etc. The network device inputs the first number of first measurement results into the second prediction model to obtain first prediction information output by the first prediction model.
[0287] It can be understood that the first prediction model and the second prediction model are prediction models deployed on the terminal device and the network device side respectively, and the structures of the first prediction model and the second prediction model are the same or different.

The network device determines first prediction information related to the predicted measurement results of one or more second cells based on the one or more first measurement results, thereby obtaining the first prediction information without the need to measure the one or more second cells, thereby reducing the overhead of the reference signal used for cell measurement.
[0289] In some embodiments, the first prediction information includes one or more of the following:
[0290] first indication information, where the first indication information is used to indicate whether one or more first mobility events occur, where the first mobility events are related to the first prediction result;

[0292] First information, where the first information indicates a first prediction result corresponding to the first mobility event that occurs.
[0293] In the embodiment of the present application, the first indication information may be used to indicate whether one or more first mobility events occur in the terminal device.
[0294] It is understandable that 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.
[0295] In some embodiments, the one or more first mobility events are preset mobility events. In this case, the first indication information is used to indicate whether the preset mobility event occurs.
[0296] If a first mobility event occurs, the second indication information is used to indicate which first mobility event has occurred. It is understandable that if multiple first mobility events occur, the first prediction information includes multiple second indication information, and different second indication information indicates the event type of different first mobility events.
[0297] The first information is used to indicate a first prediction result corresponding to a first mobility event that has occurred.
[0298] In some embodiments, the one or more first mobility events include one or more of the following first events:
[0299] The first event A and the one or more second cells corresponding to the one or more first mobility events include a serving cell, and a link performance of the serving cell measured and / or predicted based on layer 1 is better than a first threshold;
[0300] First event B: the one or more second cells include a serving cell, and the link performance of the second cell, which is a serving cell measured and / or predicted based on layer 1, is weaker than a second threshold;
[0301] First event C: the one or more second cells include a candidate cell and a serving cell, and a link performance of the candidate cell measured and / or predicted based on layer 1 is better than a first link performance, where the first link performance is the link performance of the serving cell plus a first offset;
[0302] First event D: the one or more second cells include a candidate cell, and the link performance of the candidate cell measured and / or predicted based on layer 1 is better than a third threshold;
[0303] First event E: the one or more second cells include a candidate cell and a serving cell, the link performance of the serving cell based on layer 1 measurement and / or prediction is weaker than a fourth threshold, and the link performance of the candidate cell based on layer 1 measurement and / or prediction is better than a fifth threshold;
[0304] First event F: the one or more second cells include a candidate cell, and interference of the candidate cell measured and / or predicted based on layer one is stronger than a first interference threshold.
[0305] It can be understood that 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.
[0306] The one or more first mobility events predicted by the network device based on the one or more first measurement results include one or more of first events A to F.
[0307] For the threshold values such as the first threshold to the fifth threshold and the first interference threshold involved in the first event A to the first event F, the values of different threshold values may be the same or different.
[0308] In the embodiment of the present application, the link performance of the cell may be represented by one or more parameters of the cell's L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR that characterize the link quality of the cell.
[0309] It is understandable that if the second cell has a first measurement result and a first prediction result, the network device may determine whether the first mobility event has occurred in the second cell based on the first measurement result and / or the first prediction result of the second cell. Optionally, the network device determines whether the first mobility event has occurred in the second cell based on the first measurement result of the second cell. Optionally, the network device determines whether the first mobility event has occurred in the second cell based on the first prediction result of the second cell. Optionally, the network device determines whether the first mobility event has occurred in the second cell based on whichever of the first measurement result and the first prediction result of the second cell has better link performance.
[0310] In some embodiments, the one or more first mobility events include one or more of the following second events:

[0316] Second event F: the one or more second cells include a candidate cell, and interference of a candidate beam of the candidate cell measured and / or predicted based on layer one is stronger than a second interference threshold.
[0317] In the embodiment of the present application, the second event is a mobility event at the spatial filter level related to the performance of the serving spatial filter and / or the performance of the candidate spatial filters.
[0318] It can be understood that the spatial filter of the serving cell is divided into a serving spatial filter and a candidate spatial filter, and the spatial filter of the candidate cell is the candidate spatial filter.
[0319] The one or more first mobility events predicted by the network device based on the one or more first measurement results include one or more of second events A to F.
[0320] For the threshold values such as the sixth threshold to the tenth threshold and the second interference threshold involved in the second event A to the second event F, the values of different threshold values may be the same or different.
[0321] In an embodiment of the present application, the performance of the spatial filter may be represented by one or more parameters of the spatial filter, including L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR, which characterize the link quality of the spatial filter.
[0322] In the embodiment of the present application, the first mobility event determined by the network device based on one or more first measurement results may be a cell-level mobility event or a spatial filter-level mobility event.
[0323] If the network device determines multiple first mobility events based on one or more first measurement results, the multiple first mobility events may all be cell-level mobility events, or all may be spatial filter-level mobility events, or some may be cell-level mobility events and some may be beam-level mobility events.

[0344] In an example, if the first mobility event includes the second event A, the first information includes an index of the serving cell and / or a link quality of the serving cell.
[0345] In one example, if the first mobility event includes the second event A, the first information includes an index of a serving cell and / or a link quality of the serving cell, and an index of a serving spatial filter and / or a link quality of the serving spatial filter.
[0346] If the first mobility event of the spatial filter level is related to the candidate spatial filter, 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 manner of the plurality of first measurement results includes one of the following:
[0355] Transmitted in a first transmission mode and in a first order, where the first order is an order of a preconfigured or predefined first set, and one first set includes one or more second measurement resources corresponding to the first cell;
[0356] The second transmission mode is to transmit in accordance with the first order and the second order, where the second order is the order of the second measurement resources in the first set.
[0357] In an embodiment of the present application, the terminal device may report multiple first measurement results based on the first transmission mode or the second transmission mode.
[0358] In the first transmission mode, the terminal device reports according to the order of the pre-configured or arranged first set, and the network device determines the first set corresponding to the received measurement result according to the order of the pre-configured or arranged first set. 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, and then reports the measurement results of the measurement resources in Set B2, until the measurement results of the measurement resources in Set B are reported. N The measurement results received by the network device are: the measurement results of the measurement resources in Set B1, the measurement results of the measurement resources in Set B2, ..., the measurement results of the measurement resources in Set B N The measurement results of the measured resources.
[0359] When multiple first measurement results are transmitted in the first order, each first measurement result includes a resource index and a link quality, but may not include Set B n The index of .
[0360] When multiple first measurement results are transmitted according to the first order, avoid reporting Set B n The index reduces the reporting overhead, so that more resource indexes and corresponding link qualities can be reported.
[0361] In the second transmission mode, the terminal device not only transmits data in accordance with the pre-configured or arranged first set Set B, but also transmits data in accordance with the pre-configured or arranged first set Set B. n For each first set, the measurement resources in the first set are also reported according to the order of the measurement resources in the first set. The network determines the first set corresponding to the received measurement result according to the pre-configured or arranged order of the first sets, and for each first set, the measurement resources corresponding to the received measurement result are also determined according to the order of the measurement resources in the first set. In an 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, and then reports the measurement results of the measurement resources in Set B2, until the measurement results of the measurement resources in Set B are reported. N The measurement results of the measurement resources in Set B n , Set B n There are 16 resources in total, and the link quality corresponding to the 16 measurement resources can be reported according to a specific resource order.

[0362] When multiple first measurement results are transmitted in the first order, each first measurement result includes the link quality and may not include Set Bn Index and resource index.
[0363] When the multiple first measurement results are transmitted according to the first order and the second order, the reporting overhead of resource index occupancy can be further saved.
[0364] It is understandable that the measurement resources are configured by the network device, so 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 multiple first measurement results includes:
[0366] The third transmission mode is based on reporting instance transmission, where one reporting instance includes multiple spatial filter reporting instances.
[0367] When the terminal device reports multiple first measurement results according to the third transmission mode, the reported multiple first measurement results are divided into multiple reporting instances, one reporting instance includes multiple spatial filter reporting instances, and the network side connects the multiple spatial filter reporting instances in series to obtain a reporting instance, and completes the reception of multiple first measurement results by receiving multiple reporting instances.
[0368] The spatial filter reporting instance may include the link quality of the spatial filter. The measurement result is placed in the spatial filter reporting instance and sent from the terminal device to the network device via an uplink control channel or data channel.
[0369] In the embodiment of the present application, the first transmission mode and the second transmission mode increase the capacity of the reported content by reducing the reported content, and the third transmission mode can be used in combination with the first transmission mode or the second transmission mode.
[0370] In some embodiments, the reporting instance includes fourth indication information, and the fourth indication information is used to indicate the order of multiple spatial filter reporting instances included in the reporting instance.
[0371] In the reported reporting instance, the terminal device informs the network device which spatial filter reporting instances are used in sequence in the current reporting instance 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.

[0382] In the embodiment of the present application, the target cell indicated by the fifth information may belong to the first cell or may not belong to the first cell. It is understandable 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, and the first measurement resource is used for measuring the target cell and / or reporting the measurement result.
[0384] When 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, first measurement resources, and the terminal device may complete the measurement and / or reporting of the target cell and / or target beam through the first measurement resources.

[0409] The following further describes the wireless communication method provided in the embodiments of the present application.
[0410] Considering the UE's Radio Resource Management (RRM) measurement behavior at Layer 1, mobility events triggered by Layer 1 / Layer 2 measurements are defined.
[0411] It is 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 the UE measures N beams within a candidate cell (based on Channel State Information-Reference Signal (CSI-RS) resources and / or SSB resources), the number of resources with L1-RSRP greater than a certain RSRP threshold is S. These S L1-RSRP values are then linearly averaged to obtain the averaged cell-level L1-RSRP.
[0413] In some embodiments, the cell-level predicted mobility event is 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 measurement and / or prediction is weaker than a specific threshold;
[0416] c. The link performance of the candidate cell measured and / or predicted based on Layer 1 is better than that of the current serving cell (including PCell and SCell) plus an offset;
[0417] d. The link performance of the candidate cell based on layer 1 measurement and / or prediction 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 specific threshold, and the link performance of the candidate cell based on layer 1 measurement and / or prediction is better than a specific threshold;
[0419] f. The interference of the candidate cell measured and / or predicted based on layer 1 is stronger than a certain threshold for the UE.
[0420] Events a to f are second events at the cell level.
[0421] For different events, the terminal device may be triggered to perform the same or different actions.
[0422] In one example, for a terminal device, the actions triggered by each event from event a to event f are:
[0423] For event a, the UE does not need to report the event and keeps measuring the event;
[0424] For event b, the UE may report the event, including the index of the serving cell and / or the link quality of the serving cell; wherein, the NW may subsequently instruct the UE to switch to a candidate cell (for cell handover, the candidate cell may also be referred to as a target cell);
[0425] For event c, the UE may 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 may subsequently instruct the UE to switch to the candidate cell;
[0426] For event d, the UE may report the event, including the index of the candidate cell and / or the link quality of the candidate cell, wherein the NW may subsequently instruct the UE to switch to the candidate cell;
[0427] For event e, the UE may 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 may subsequently instruct the UE to switch 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 on the UE's serving cell, wherein the NW can subsequently adjust the transmission power of the beam used by the candidate cell to reduce interference or avoid using the interfering beam and scheduling the interfered UE at the same time.
[0429] The beam-level predicted mobility events are 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 specific threshold;
[0432] 3. The performance of the candidate beam of the candidate cell measured and / or predicted based on layer 1 is better than the serving beam performance of the current serving cell (including PCell and SCell) plus an offset;
[0433] 4. The performance of the candidate beam of the candidate cell based on layer 1 measurement and / or prediction 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 specific threshold, and the performance of the candidate beam of the candidate cell based on layer 1 measurement and / or prediction is better than a specific threshold;
[0435] 6. The interference of the candidate beam of the candidate cell measured and / or predicted based on layer 1 is stronger than a certain threshold for the UE.
[0436] Events one to six belong to the second events at the beam level.
[0437] In one example, for a terminal device, the actions triggered by each of events 1 to 6 are:
[0438] For event 1, the UE does not need to report the event and keeps measuring the event;
[0439] For event 2, the UE may 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 may subsequently instruct the UE to switch the current serving beam to another beam (the beam may be from the current serving cell or a candidate cell);
[0440] For event three, the UE may 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, wherein the NW may subsequently instruct the UE to switch the current serving beam to another beam (the beam may be from the current serving cell or the candidate cell);
[0441] For event 4, the UE may 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. The NW may subsequently instruct the UE to switch to the candidate beam in the candidate cell.
[0442] For event 5, the UE may 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, wherein the NW may subsequently instruct the UE to switch the current serving beam to another beam (the beam may be from the current serving cell or the 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 the interference of the candidate beam on the UE's service beam, wherein the NW can subsequently adjust the transmission power of the beam used by the candidate cell to reduce interference or avoid using the interfering beam and scheduling the interfered UE at the same time.
[0444] It should be noted that in some embodiments, the indicator for measuring a cell-level or beam-level performance is L1-RSRP. In other embodiments, it may also be L1-RSRQ, L1-RSSI, L1-SINR, SNR, or a combination of multiple indicators.
[0445] The UE compares the preset mobility event with the prediction result of the model to determine whether a layer 1 / layer 2 mobility event occurs.
[0446] The wireless communication method provided in the embodiments of the present application includes but is not limited to the following embodiment 1 and embodiment 2.
[0447] Example 1: Mobility event prediction with model deployed on UE side
[0448] If the model is deployed on the UE side, the wireless communication method provided in the embodiment of the present application, as shown in Figure 19, includes S1901 to S1905.
[0449] S1901. UE reports its capabilities.
[0450] The UE reports its ability to measure and predict the mobility events (including cell-level and beam-level) it supports. Specifically, the UE first informs the NW whether it supports spatial domain measurement and / or prediction of mobility events. If the UE capability supports it, the UE needs to continue to report one or more combinations of the following information for the NW to perform subsequent configuration. UE capabilities include but are not limited to:
[0451] Information 1: On a carrier, what types of mobility events does the UE-side model support for prediction?
[0452] Information 2: On one carrier, the UE supports measurement of a maximum number of candidate cells;
[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, on one carrier, the UE supports a maximum number of measurement sets for measurement, and in each measurement set, a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources) are measured.
[0455] Information 3: On one carrier, the UE supports 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] In each prediction set, a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources) are predicted.
[0458] S1902. The NW configures measurement resources 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:
[0460] The NW configures the measurement set Set B of the candidate cells (including the serving cell) 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 the 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, and C. The measurement set and prediction set for cell #1 are identified as SetB1 and SetA1, respectively, and SetB1 is a subset of SetA1. The measurement set and prediction set for cell #2 are identified as SetB2 and SetA2, respectively, and SetB2 is a subset of SetA2. The measurement set and prediction set for cell #3 are identified as SetB3 and SetA3, respectively, and SetB3 is a subset of SetA3.
[0462] In addition, the NW optionally configures some uplink resources (PUSCH or PUCCH) for the UE. When an event that needs to be reported occurs, the uplink resources are used to carry the report of the model-predicted event. In some embodiments, the NW configures PUCCH resources for the UE to request uplink resources, such as for carrying a Scheduling Request (SR).
[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 of the candidate cell (including the serving cell), namely CSI-RS resources and / or SSB resources. In addition, the prediction set Set A m (1<=m<=M) may also include one or more downlink measurement resources.
[0464] In the embodiments of the present application, we consider the prediction of mobility events 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 64 transmit beams in total, but in order to reduce the measurement overhead and delay, Set B n There are only 8 transmit beams.
[0465] In some other embodiments, Set B n With Set A m Can also be different, for example, Set B n The SSB-based wide beams included in Set A (fewer in number) m The narrow beams (large number) are based on CSI-RS.
[0466] In some other embodiments, a candidate cell may correspond to only one prediction set but no corresponding measurement set. The model may use measurements of other candidate cells as input to infer the cell-level and / or beam-level link quality of the candidate cell (without a corresponding measurement set), as well as LTM mobility events.
[0467] The configuration signaling used by the NW may be RRC signaling.
[0468] S1903: The UE infers a mobility event through a model.
[0469] When the UE completes the measurement, it is measurement set Set B n The measurement results (1<=n<=N) are used as the input of the model, and the model performs inference.
[0470] The prediction result includes one or more combinations of the following inferences. The inference result should be from the prediction set Set A m Select from (1<=m<=M).
[0471] Whether a mobility event configured, indicated, or preset by the NW occurs.
[0472] If a mobility event occurs, which mobility event (i.e., event type) and other important event information:
[0473] Serving cell information, and / or serving beam information, and / or serving beam link quality corresponding to the event;
[0474] The candidate cell information, and / or candidate beam information, and / or candidate beam link quality corresponding to the event.
[0475] The relationship between the input and output of model 2101 can be shown in Figure 21. The input of model 2101 includes: the measurement results corresponding to each set in set B1 (SetB1) to set BN (SetBN), and the output of the model includes: LTM event type (LTM event type), candidate cell information and serving cell information, wherein the candidate cell information includes: the candidate cell's cell index and / or resource (beam) index and / or cell-level link quality and / or beam-level link quality, and the serving cell information includes: the serving cell's 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 cell or serving cell output by model 2101 is the cell corresponding to set Am.
[0476] It should be noted that the model in the embodiments of the present application may be a DNN, CNN, RNN or other 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] The index of the candidate cell (better than the current serving cell plus an offset)
[0480] ●Link quality of candidate cells (cell level)
[0481] ● Link quality of the current serving cell (cell level)
[0482] For example, for beam-level mobility event prediction, the model outputs one or more of the following information:
[0483] Event Type 5
[0484] Index of candidate cells
[0485] Candidate beam index of the candidate cell (expressed as downlink reference signal resource index)
[0486] Link quality of candidate cells (beam level)
[0487] Serving cell index
[0488] Serving beam index of the serving cell (expressed as the resource index of the downlink reference signal)
[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 independently decide whether to report the predicted mobility event results based on the AI / ML model. For example, if the model predicts that the UE's current serving cell is better than a specific threshold (Event A) and maintains an appropriate serving cell link state, the UE does not need to report the results and does not need to trigger subsequent LTM mobility operations.
[0492] In other embodiments, the UE reports the predicted results of mobility events based on NW configuration or instructions or predefined in the protocol. For example, if the optimal cell output by the model is a candidate cell (different from the serving cell) and its performance is better than the current serving cell plus an offset (e.g., 6dB), 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] Regarding the content of the predicted mobility event report, the UE may report it according to the model output. The report content may include at least one of the following information:
[0494] The types of mobility events predicted to occur;
[0495] 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 reporting predicted mobility events, the UE can use control signaling at the physical layer or higher layers. In some embodiments, when the model infers that a pre-defined mobility event has occurred, the UE decides to report it. This reporting resource may be a periodic PUCCH. This resource is pre-configured by the network and does not require the UE to request it.
[0498] In some other embodiments, the process can be described as follows:
[0499] 1. The output of the UE-side model triggers a mobility event (e.g., the link quality of the candidate cell is sufficiently better than that of the current serving cell, for example, greater than a certain offset, such as 6dB L1-RSRP);
[0500] 2. The UE requests resources for mobility prediction event reporting, such as by sending a special scheduling request (SI) for AI / ML prediction purposes to the NW;
[0501] 3. The NW agrees to the UE's reporting request, sends an uplink scheduling DCI, and allocates uplink resources to the UE;
[0502] 4. The UE uses the PUSCH scheduled by the NW to carry the mobility-related report
[0503] In some other embodiments, the reporting of the mobility event may be included in a MAC CE of the MAC layer, or in mobility-related signaling of a higher layer (such as an RRC layer).
[0504] S1905. The NW indicates mobility information to the UE.
[0505] Mobility information can be understood as the third information. The NW can send a Cell Switch Command (CSC) to the UE. This command carries a MAC CE bearer, which contains a TCI state ID and a candidate cell index, indicating a candidate beam and candidate cell, respectively. After receiving the CSC, the UE completes the cell switching operation within a specified timeframe.
[0506] For mobility events predicted based on AI / ML in the embodiments of the present application, it is very likely that the candidate beams and / or candidate cells predicted by the model are ones that the UE has not measured before. In this case, a set of measurement resources (such as a set of CSI-RS resources and / or SSB resources) can be additionally indicated in the cell handover command, and the UE can complete the measurement and / or reporting of the target cell and / or target beam using the indicated resources. B1
[0507] For example, the UE can achieve downlink synchronization by measuring the SSB resources of the target cell and adjust the downlink receive spatial filter (beam). The UE can track the time and frequency by measuring the CSI-RS (Tracking RS) of the target cell, or obtain the CSI information of the cell in advance and feed it back to the NW.
[0508] Example 2: Mobility event prediction with model deployed on the NW side
[0509] If the model is deployed in the NW, the wireless communication method provided in the embodiment of the present application, as shown in FIG22 , includes S2201 to S2205.
[0510] S2201. UE reports its capabilities.
[0511] The UE reports its ability to measure and predict the mobility events (including cell-level and beam-level) it supports. Specifically, the UE first informs the NW whether it supports spatial domain measurement of mobility events. If the UE capability supports it, the UE needs to continue to report one or more combinations of the following information for the NW to perform subsequent configuration. UE capabilities include but are not limited to:
[0512] Information 1: On one carrier, the UE supports measurement of a maximum number of candidate cells;
[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, on one carrier, the UE supports a maximum number of measurement sets for measurement, and in each measurement set, a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources) for measurement.
[0515] It should be noted that since the model is deployed on the NW side, the UE does not need to report its prediction capability for mobility events.
[0516] S2202: The NW configures measurement resources.
[0517] Based on the UE's capability report, the NW configures resources for the UE, including but not limited to the following:
[0518] Resource 1, NW configures the measurement set Set B of the candidate cell (including the serving cell) for the UE n (1<=n<=N).
[0519] In addition, the NW may optionally configure some uplink resources (PUSCH or PUCCH) for the UE. n After the measurement of (1<=n<=N), the uplink resource is used to carry the report of the measurement result. n (1<=n<=N) includes downlink measurement resources of 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 of the candidate cell (including the serving cell), namely, CSI-RS resources and / or SSB resources.
[0521] The configuration signaling used by the NW may be RRC signaling.
[0522] It should be noted that, since the model is deployed in the NW, the NW does not need to configure the prediction set of mobility events for the UE.
[0523] S2203: The UE measures and reports the measurement result.
[0524] According to the configuration of the NW, the UE measures the resource set Set Bn (1<=n<=N) of the mobility event. The UE measures and obtains the link quality corresponding to the resources in the set, such as L1-RSRP.
[0525] The UE reports the measurement results to the NW via uplink signaling. In some embodiments, the uplink signaling is reported in the form of beam reporting in the UCI of the physical layer. The UCI can be carried by PUCCH or PUSCH. It should be emphasized that because Set B n (1<=n<=N) includes the serving cell and multiple candidate cells, so the measurement amount is often large. According to the NR tradition, each report contains a maximum of 4 reference signal resource indices and the corresponding link quality (such as L1-RSRP), which is obviously difficult to meet the carrying requirements.
[0526] The embodiments of the present application consider enhancing the capacity of uplink beam reporting in the following manner.
[0527] The first mode is the first transmission mode. The UE performs the measurement according to the pre-configured or arranged measurement set Set B. n 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 the measurement results of the measurement resources in Set B are reported. N The measurement results of the measured resources in Set B include the resource index and link quality, but do not include the resource index and link quality of Set B. n In Table 1, the UE reports the measurement results of N measurement sets in total, assuming that each measurement set contains M measurement resources. In some embodiments, the number of resources in each measurement set may be different. Reporting the measurement results based on the first method can avoid reporting Set B. n The index reduces the reporting overhead, so that more resource indexes and corresponding link qualities can be reported.
[0528] Table 1 Example of reported measurement results
[0529] Among them, the field CRI or SSBRI#1 is used to indicate the resource index to be reported. Only CRI or SSBRI, or both, can be reported.
[0530] The second mode is the second transmission mode. The UE not only follows the pre-configured or arranged measurement set Set B n The order of the resources in each measurement set is also reported, as shown in Table 2. For Set B n , report RSRP according to the resource set resource beat information. For example, in Set B n There are 16 resources in total. 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 the resource index.
[0531] Because the measurement resources are configured by the NW, the NW side can understand the resource index and measurement set index corresponding to the reported link quality.
[0532] Table 2 Example of reported measurement results
[0533] The third method, namely the third transmission method, is different from the first and second methods (increasing the capacity of the reporting content by reducing the reporting content). It considers connecting multiple reporting instances, such as beam reporting instance #1, beam reporting instance #3, and beam reporting instance #6, to form a complete reporting content.
[0534] The premise for this is that the UE needs to inform the NW in the reporting content which beam reporting instances it used in turn to report the complete measurement set Set B n (1<=n<=N). In some other embodiments, the NW may also inform the UE, by 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 some other embodiments, the uplink signaling may be MAC CE or RRC signaling.
[0537] S2204. NW infers mobility events through the model.
[0538] The NW side model performs similar inference as the UE side model. Please refer to the description of S1904 here.
[0539] S2205. The NW indicates mobility information to the UE.
[0540] The description of S2205 is the same as that of S1905 and is not repeated here.
