[0074] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0075] 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.

[0076] 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.

[0077] 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.

[0079] 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.

[0080] 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.

[0081] The terminal device 110 can be used for device-to-device (D2D) communication.

[0082] 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).

[0086] 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.

[0087] 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.

[0088] Layer 1 / Layer 2 Triggered Mobility (LTM)

[0089] 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 standardized 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., the target cell) and / or the selected beam through the cell switching command, so that the UE switches to the candidate cell and / or the selected beam indicated by the cell switching command.

[0090] 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.

[0091] 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)).

[0092] Artificial Intelligence (AI) / Machine Learning (ML) Models

[0093] 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.

[0094] [Corrected 21.02.2024 according to Rule 91] A simple neural network is shown in Figure 3, which includes an input layer 301, a hidden layer 302, and an output layer 303. Through the different connection methods, weights, and activation functions of multiple neurons, different outputs can be generated, thereby fitting the mapping relationship from input to output. Each upper-level node is connected to all of its lower-level nodes. This fully connected model can also be called a deep neural network (DNN) or a convolutional neural network (CNN). This neural network (NN) model can perform beam prediction in the spatial domain.

[0095] Next, we'll introduce a typical recurrent neural network (RNN): the Long Short-Term Memory (LSTM) network. The LSTM network is a time-domain prediction model. LSTM is a neural network that models sequential data and has achieved remarkable results in natural language processing applications such as machine translation and speech recognition.

[0096] Neural networks memorize information from past moments and use it in calculating current outputs. This means that nodes in the hidden layers are no longer disconnected but connected, and the hidden layer inputs include not only the input layer but also the output of the previous hidden layer. Common RNN structures include LSTM and Gated Recurrent Unit (GRU). Figure 4 shows an example of a basic LSTM cell structure, including a forget gate composed of sigmoid (σ), an input gate composed of σ and tanh, and an output gate composed of σ, ×, and tanh. × represents vector element-wise multiplication, and + represents vector element-wise addition. The LSTM cell state determines which states should be retained and which should be forgotten, addressing the long-term memory limitations of traditional RNNs. The LSTM cell shown in Figure 4 enables the establishment of long-range temporal dependencies.

[0097] In the embodiment of the present application, the prediction of candidate cells and candidate beams (pairs) in the time domain can be performed using the 0LSTM model shown in Figure 5. The LSTM model shown in Figure 5 can be understood as extending K historical moments as input in terms of time sequence, which is equivalent to a cascade of K LSTM units 501. Each LSTM unit input is Set B n,k (1<=n<=N, 1<=k<=K) measurement results at the measurement moments, wherein the input of the first LSTM unit 501 is the measurement value of the CSI-RS or SSB at the K-1th moment in the past and / or the associated cell index and / or the associated beam index, ..., the input of the K-1th LSTM unit 501 includes: the output of the K-2th LSTM unit 501 and the measurement value of the CSI-RS or SSB at the 1st moment in the past and / or the associated cell index and / or the associated beam index, the input of the Kth LSTM unit 501 includes: the output of the K-1th LSTM unit 501 and the measurement value of the CSI-RS or SSB at the 0th moment in the past and / or the associated cell index and / or the associated beam index, and the output of the Kth LSTM unit 501 includes the index, residence time and link quality of the optimal candidate cell and the optimal beam in the next period of time.

[0098] After completing the input of measurement results at K moments, the LSTM model can predict the optimal candidate cell and optimal beam (pair), link performance, and the dwell time of the optimal cell and optimal beam (pair) over the next period of time.

[0099] The CNN in the embodiment of the present application takes LSTM as an example, but CNN can be replaced by other network structures including but not limited to DNN, CNN, etc.

[0100] 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.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] Therefore, using AI / ML techniques to predict future mobility, i.e., measurement results and / or LTM events at future moments, can be a technical path to solve the mobility problem.

[0106] 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.

[0109] The one or more first measurement results include a first measurement result corresponding to each first moment in a second number of first moments of a first number of first cells, the first measurement result being a measurement result obtained by measuring the first cell, the first moment being a historical moment, the first number being greater than or equal to 1, and the second number being greater than or equal to 1;

[0110] The first prediction information is related to one or more first prediction results, and the one or more first prediction results include the first prediction results corresponding to each second moment of a third number of second cells in a fourth number of second moments. The first prediction result is the measurement result of the second cell predicted based on the one or more first measurement results. The second moment is a future moment. The third number is greater than or equal to 1, and the fourth number is greater than or equal to 1.

[0111] The terminal device measures the first number of first cells at each first moment in the second first moment, and obtains the first number*second number of first measurement results.

[0112] It can be understood that, for a first cell at a first moment, 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] After determining the first measurement results of the first number of first cells at each of the second number of first moments, the terminal device predicts first prediction information based on the first number * the second 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.

[0117] The first prediction result is the measurement result of the second cell at the second moment predicted based on the third number * the fourth number of first measurement results. The first number * the second number of first measurement results can be used to predict the first prediction result of the third number of second cells at each of the fourth number of second moments, i.e., the third number * the fourth number of first prediction results. It is understood that the second moment is a future moment that has not yet occurred, and the first prediction result is the measurement result of the second cell at the second moment predicted or inferred based on the N * K first measurement results.

[0118] 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, that is, the first number of first cells and the third number of second cells may include the same cell or may not include the same cell.

[0119] In one example, a terminal device obtains first prediction information related to the prediction results of cell 1, cell 2, and cell 3 at future time 1 and future time 2 based on the measurement results of cell 1, cell 2, and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 1, cell 2, and cell 3 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2, and cell 3 at historical time 1 and historical time 2.

[0120] In one example, a terminal device obtains first prediction information related to the prediction results of cell 4 and cell 5 at future time 1 and future time 2 based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 4 and cell 5 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2.

[0121] In one example, a terminal device obtains first prediction information related to the prediction results of cell 3 and cell 4 at future time 1 and future time 2 based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 3 and cell 4 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2.

[0122] In some embodiments, a first prediction model is deployed in a 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 an RNN). The terminal device inputs first measurement results of a first number of first cells at a second number of historical moments into the first prediction model to obtain first prediction information output by the first prediction model.

[0123] In an embodiment of the present application, the terminal device predicts first prediction information related to the prediction result at a future moment based on the measurement result at a historical moment, thereby realizing time domain prediction of the measurement result.

[0124] In a wireless communication method provided by an embodiment of the present application, a terminal device determines first prediction information related to one or more predicted first prediction results based on first measurement results of a first number of first cells at each historical moment in a second number of historical moments, wherein the one or more first prediction results include prediction results of a third number of second cells at each future moment in a fourth number of future moments, and the first or more first prediction results are measurement results predicted based on the one or more first measurement results. Thus, when one or more first cells are measured at a historical moment, first prediction information related to the measurement results of one or more second cells at a future moment is predicted, thereby reducing the overhead of reference signals used for cell measurement and preparing a response method in advance based on the first prediction information, thereby reducing the delay and other adverse effects caused by mobility.

[0125] In some embodiments, based on FIG6 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG7 , including:

[0126] S701: The terminal device sends second information, where the second information is used to indicate a second mobility event, the second mobility event is a reported first mobility event, and the first mobility event is related to a first prediction result.

[0127] 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.

[0128] In some embodiments, an embodiment of the present application provides a wireless communication method, applied to a network device, as shown in FIG8 , including:

[0129] S801. A network device receives second information, 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.

[0130] The one or more first measurement results are used to predict first prediction information, the one or more first measurement results include a first measurement result of a first number of first cells corresponding to each first moment in a second number of first moments, the first moment being a historical moment, the first number being greater than or equal to 1, and the second number being greater than or equal to 1;

[0131] The first prediction information is related to one or more first prediction results, and the one or more first prediction results include the first prediction results corresponding to each second moment of a fourth number of second moments of a third number of second cells, the second moment is a future moment, the third number is greater than or equal to 1, and the fourth number is greater than or equal to 1.

[0132] The wireless communication method shown in FIG. 7 or FIG. 8 is further described below.

[0133] The terminal device determines, based on the first prediction result, that a first mobility event has occurred on the terminal device, and the first mobility event is a reported mobility event, i.e., a second mobility event. The terminal device 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 the second mobility event.

[0134] 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.

[0135] 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.

[0136] 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.

[0137] In some embodiments, the first prediction information includes one or more of the following:

[0138] 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;

[0139] second indication information, where the second indication information is used to indicate an event type of the first mobility event that occurred;

[0140] First information, where the first information indicates a first prediction result corresponding to the first mobility event that occurs.

[0141] In the embodiment of the present application, the first indication information may be used to indicate whether one or more first mobility events occur at the second moment in the terminal device.

[0142] 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.

[0143] In this embodiment of the present application, first measurement results of a first number of first cells at a second number of first moments are used to predict first prediction results of a third number of second cells at a fourth number of second moments. For each second moment in the fourth number of second moments, whether a first mobility event occurs at the second moment is determined based on the first prediction results of the third number of second cells at the second moment.

[0144] It can be understood that the first indication information may be used to indicate whether the first mobility event occurs at the fourth number of second moments.

[0145] 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.

[0146] 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.

[0147] At a second moment, one or more first mobility events may not occur or may occur.

[0148] In some embodiments, the event types of the first mobility events occurring at different second moments are the same or different.

[0149] The first information is used to indicate a first prediction result corresponding to a first mobility event that has occurred.

[0150] It is understandable that in the embodiment of the present application, the first mobility event that occurs may be a mobility event that may occur at all or part of the second moments in the predicted fourth number of second moments.

[0151] The mobility event in the embodiment of the present application is an event related to the mobility of the terminal device that may occur at the second moment based on the prediction of the third number of first moments. Therefore, the mobility event in the embodiment of the present application can be understood as a mobility event in the time domain.

[0152] In some embodiments, the one or more first mobility events include one or more of the following first events:

[0153] 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 the predicted link performance of the serving cell is better than a first threshold;

[0154] First event B: the one or more second cells include a serving cell, and the predicted link performance of the serving cell is weaker than a second threshold;

[0155] First event C: the one or more second cells include a candidate cell and a serving cell, the predicted link performance of the candidate cell is better than the first link performance, and the first link performance is the predicted link performance of the serving cell plus a first offset;

[0156] First event D: the one or more second cells include a candidate cell, and the predicted link performance of the candidate cell is better than a third threshold;

[0157] First event E: the one or more second cells include a candidate cell and a serving cell, the predicted link performance of the serving cell is weaker than a fourth threshold, and the predicted link performance of the candidate cell is better than a fifth threshold;

[0158] First event F: the one or more second cells include a candidate cell, and the predicted interference of the candidate cell is stronger than a first interference threshold.

[0159] 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.

[0160] At the second moment, the terminal device predicts, based on the one or more first measurement results, that the one or more first mobility events occurring at the second moment include one or more of first events A to first events F.

[0161] 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.

[0162] In an embodiment of the present application, the link performance of the cell can be represented by one or more parameters characterizing the link quality of the cell, including L1-reference signal received power (RSRP), L1-reference signal received quality (RSRQ), L1-received signal strength indication (RSSI), L1-signal to interference plus noise ratio (SINR), and signal-to-noise ratio (SNR).

[0163] In some embodiments, the one or more first mobility events include one or more of the following second events:

[0164] Second event A: the one or more second cells corresponding to the one or more first mobility events include a serving cell, and the predicted performance of a serving space filter of the serving cell is better than a sixth threshold;

[0165] Second event B: the one or more second cells include a serving cell, and the predicted performance of the serving spatial filter of the serving cell is weaker than a seventh threshold;

[0166] Second event C: the one or more second cells include a candidate cell and a serving cell, and the predicted performance of the candidate spatial filter of the candidate cell is better than the second link performance, where the second link performance is the predicted performance of the serving spatial filter of the serving cell plus a second offset;

[0167] A second event D: the one or more second cells include a candidate cell, and the predicted performance of the candidate spatial filter of the candidate cell is better than an eighth threshold;

[0168] Second event E: the one or more second cells include a candidate cell, the predicted performance of the serving spatial filter of the serving cell is weaker than a ninth threshold, and the predicted performance of the candidate spatial filter of the candidate cell is better than a tenth threshold;

[0169] Second event F: the one or more second cells include a candidate cell, and the predicted interference of the candidate beam of the candidate cell is stronger than the second interference threshold.

[0170] 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.

[0171] 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.

[0172] For the second moment, the one or more first mobility events corresponding to the second moment predicted by the terminal device based on the one or more first measurement results include one or more of second events A to second events F.

[0173] 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.

[0174] 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.

[0175] In the embodiment of the present application, the first mobility event determined based on the one or more first measurement results may be a cell-level mobility event or a spatial filter-level mobility event.

[0176] In the embodiment of the present application, the multiple first mobility events determined based on the one or more first measurement results may be a first mobility event at one second moment, or may be the first mobility events at multiple second moments.

[0177] For the second moment, if the terminal device determines multiple first mobility events based on one or more first measurement results, the multiple first mobility events corresponding to the second moment 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.

[0178] In one example, if the first event A occurs, the first prediction information includes at least one of the following information:

[0179] 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; an event type of the first event A; and first information corresponding to the first event A.

[0180] 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: first indication information having a first value; the event type of the first event A and the event type of the second event B; the first information corresponding to the first event A and the first information corresponding to the second event B.

[0181] In an example, if the first mobility event does not occur, the first prediction information includes at least one of the following information: first indication information whose value is a second value, wherein the first indication information whose value is the second value indicates that the first mobility event does not occur.

[0182] In some embodiments, the first information includes one or more of the following: a time index, the time index being used to indicate a second moment corresponding to a corresponding mobility event; a cell index and / or a cell link quality; a cell link quality and / or a spatial filter link quality.

[0183] For the first mobility event that occurs, the first prediction information may indicate the time at which the first mobility event occurs, that is, the second time corresponding to the first mobility event.

[0184] In the embodiment of the present application, the first mobility event may be a cell-level mobility event or a spatial filter-level mobility event.

[0185] It is understandable that the first mobility event includes a cell-level first mobility event, and the first information corresponding to the cell-level first mobility event includes cell information corresponding to the first mobility event, and the cell information includes: cell index and / or cell link quality.

[0186] 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.

[0187] 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.

[0188] 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.

[0189] 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 of the spatial filter level 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.

[0190] 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.

[0191] 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.

[0192] 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.

[0193] 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.

[0194] 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.

[0195] 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.

[0196] 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.

[0197] 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.

[0198] 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:

[0199] 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;

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] 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.

[0205] 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.

[0206] In an embodiment of the present application, when the terminal device reports the first mobility event or the second mobility event, it may indicate the predicted occurrence time of the first mobility event or the second mobility event, or it may not carry the predicted occurrence time of the first mobility event or the second mobility event.

[0207] 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 occurred at the second moment 1, the second information sent by the terminal device to the network device indicates that the first time B occurred at the second moment 1 or indicates the first event B.

[0208] It is understandable that if the second information indicates the second moment when the first mobility event occurs, the second information includes a time index; if the second information does not indicate the second moment when the first mobility event occurs, the second information does not include a time index.

[0209] In some embodiments, when the terminal device reports the second mobility event, the second mobility event is: determined by the terminal device; or indicated by the network device; or predefined.

[0210] 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.

[0211] 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.

[0212] 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.

[0213] In one example, when the first prediction information indicates that the first event A occurs at the second moment 1, the terminal device does not need to report and does not need to trigger subsequent LTM mobility operations.

[0214] 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.

[0215] In some embodiments, the second information is transmitted via one or more of the following signaling:

[0216] Control signaling of the physical layer; Media Access Control layer control element MAC CE; Mobility-related signaling of the Radio Resource Control RRC layer.

[0217] 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.

[0218] In some embodiments, when the terminal device reports the second mobility event, the reporting resource may be a periodic physical uplink control channel (PUCCH).

[0219] 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.

[0220] 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).

[0221] In some embodiments, for one of the second mobility events, the second information includes one or more of the following information:

[0222] third indication information, where the third indication information is used to indicate an event type of the second mobility event;

[0223] first information corresponding to the second mobility event.

[0224] Here, the description of the first information can refer to the above description and will not be repeated here.

[0225] In some embodiments, based on FIG. 6 or FIG. 7 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG. 9 , including:

[0226] S901. The terminal device receives third information, where the third information is used to indicate a target cell and / or a target spatial filter corresponding to each second moment in the fourth number of second moments.

[0227] In some embodiments, based on FIG8 , an embodiment of the present application provides a wireless communication method applied to a network device, as shown in FIG10 , including:

[0228] S1001. The network device sends third information, where the third information is used to indicate a target cell and / or a target spatial filter corresponding to each second moment in the fourth number of second moments.

[0229] 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. The third information is used to indicate the target cell and / or target spatial filter corresponding to each second moment in the fourth quantity. It is understandable that the third information may be related to or unrelated to the second information.

[0230] Optionally, the network device sends the third information to the terminal device via a cell switch command (Cell Switch Command, CSC).

[0231] Optionally, the cell switching command itself has a MAC CE bearer, which includes at least a TCI state ID and a candidate cell index (candidate cell index), wherein the TCI state ID is used to indicate the candidate beam and the candidate cell index is used to indicate the target cell.

[0232] 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.

[0233] The third information may be carried in one or more cell switching commands, so that the target cell and / or target spatial filter corresponding to each second moment in the fourth number of second moments is carried in one or more cell switching commands.

[0234] In some embodiments, the third information is carried on a cell switching command.

[0235] The network device uses a cell switching command to indicate target cells and / or target spatial filters for a fourth number of second moments in the future to the terminal device. The terminal device determines the target cells and / or target spatial filters for the fourth number of second moments based on the cell switching command.

[0236] Understandably, the cell switching command may include up to a fourth number (F) of TCI state groups. For example, the fth TCI state group corresponds to the indication information of the cell and / or beam at the fth moment. The terminal device sequentially uses multiple TCI states indicated by the network device at different second moments.

[0237] Each TCI state group can contain one or more TCI states. When the UE operates in the Joint UL and DL TCI state mode, a joint TCI state can indicate both uplink and downlink QCL information. When the UE operates in the Separate UL and DL TCI state mode, a separate uplink and downlink TCI state can indicate uplink and downlink QCL information respectively.

[0238] In the embodiment of the present application, for the second moment, the target cell and / or target filter indicated by the third information may have been measured by the terminal device or may not have been measured by the terminal device.

[0239] In some embodiments, if the target cell and / or target spatial filter indicated by the third information includes a target cell and / or target spatial filter that has not been measured, the third information is also used to indicate a first measurement resource, which is used for measuring the target cell and / or target spatial filter that has not been measured and / or reporting the measurement results.

[0240] 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.

[0241] In one example, the terminal device can complete downlink synchronization by measuring the SSB resource in the first measurement resource and adjust the downlink receive spatial filter, etc. In one example, the terminal device can track time and frequency by measuring the CSI-RS of the target cell, or obtain the CSI information of the cell in advance and feed it back to the network device.

[0242] In some embodiments, based on FIG. 6 , FIG. 7 , or FIG. 9 , an embodiment of the present application provides a wireless communication method, applied to a terminal device, as shown in FIG. 11 , including:

[0243] S1101. The terminal device receives first configuration information, 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 measurement resources of the first number of first cells at the second number of first moments, and the one or more second sets include predicted resources of the third number of second cells at the fourth number of second moments.

[0244] In some embodiments, based on FIG. 8 or FIG. 10 , an embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG. 12 , including:

[0245] S1201. The network device sends first configuration information, 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 measurement resources of the first number of first cells at the second number of first moments, and the one or more second sets include predicted resources of the third number of second cells at the fourth number of second moments.

[0246] The first set can be called the measurement set and can be expressed as Set B n，k(1<=n<=N, 1<=k<=K), N is less than or equal to the first number, and K is equal to the second number. In one example, N is the first number, and K is the second number.

[0247] In some embodiments, one of the first sets includes measurement resources of one or more first cells at one or more first moments.

[0248] Optionally, a first set includes measurement resources of a first cell at multiple first moments.

[0249] In an example, a first set includes measurement resources of a first cell at a second number of first time instants.

[0250] Optionally, a first set includes measurement resources of multiple first cells at a first moment.

[0251] In one example, a first set includes measurement resources of a first number of first cells at a first moment. In another example, a first set includes measurement resources of a first cell at a first moment, and the first set is applied to a second number of first moments. In this case, the measurement resources of the first cell at different first moments are the same.

[0252] The second set can be called the prediction set, which can be expressed as Set A m，f (1<=m<=M, 1<=f<=F), M is less than or equal to the third number, and F is less than or equal to the fourth number. In one example, M is the third number, and F is the fourth number.

[0253] Optionally, a second set includes predicted resources of a second cell at multiple second moments.

[0254] In an example, a second set includes predicted resources of a second cell at a fourth number of second time instants.

[0255] Optionally, a second set includes predicted resources of multiple second cells at a second moment.

[0256] In an example, a second set includes predicted resources of a second cell at a second moment, and the second set is applied to a fourth number of second moments. In this case, the predicted resources of the second cell at different second moments are the same.

[0257] In some embodiments, if one of the first cells corresponds to a first set and a second set, the first set is applied to different first moments, and the second set is applied to different second moments.

[0258] The first cell also serves as the second cell. The cell has the same measurement resources at each first moment and the same prediction resources at each second moment. In this case, the first set can be identified as SetB i , represents the measurement set of cell i, and the measurement set is applied to each first moment, the second set can be identified as SetA i , represents the prediction set of cell i, and the prediction set is applied to each second moment.

[0259] In the embodiment of the present application, the measurement resources in the first set include one or more reference signal resources, and the prediction resources in the second set include one or more reference signal resources, wherein one reference signal resource corresponds to one spatial filter, i.e., a beam.

[0260] In some embodiments, the first set and the second set include the same resources, or the first set is a subset of the second set.

[0261] If the first set SetB i and the second set SetA i If the included resources are the same, it means that the resources of cell i at the historical moment and the future moment are the same. No prediction of other beams in the spatial domain is performed, and only the measurement result at the second moment is predicted in the time domain based on the measurement result at the first moment.

[0262] If the first set SetB i For the second set SetA i The first set SetB is a subset of i The resources included are the second set SetA i At this time, the measurement results of the resources in the second set are predicted based on the measurement results of the resources included in the first set, and the prediction is performed simultaneously in the spatial domain and the time domain.

[0263] In some embodiments, the second cell may or may not exist in the corresponding first set.

[0264] If the second cell has a corresponding first set, it indicates that the second cell has been measured by the terminal device as the first cell.

[0265] If there is no corresponding first set for the second cell, it indicates that the second cell has not been measured by the terminal device, and the first prediction result of the second cell is obtained based on the cell prediction, then the cell-level measurement result is predicted based on one or more first measurement results.

[0266] It is understandable that the first prediction model can use measurements of other cells as input to infer the cell-level and / or beam-level link quality of the cell (without corresponding measurement set) and LTM mobility events at future moments.

[0267] In some embodiments, the type of spatial filter corresponding to the measurement resources included in the first set and the type of spatial filter corresponding to the prediction resources included in the second set are the same as or different from each other.

[0268] The types of spatial filters include but are not limited to CSI-RS based wide beam and SSB based narrow beam.

[0269] In one example, the type of spatial filters corresponding to the resources in the first set and the second set may be a CSI-RS based wide beam.

[0270] In one example, the type of spatial filters corresponding to the resources in the first set and the second set may be SSB-based narrow beam.

[0271] In one example, the first set includes a CSI-RS-based wide beam, and the second set includes an SSB-based narrow beam.

[0272] In some embodiments, the first configuration information is further used to configure one or more of the following:

[0273] a third mobility event, where the third mobility event is a mobility event predicted by the one or more first measurement results;

[0274] 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.

[0275] The third mobility event is a mobility event that can be predicted based on the one or more first measurement results.

[0276] 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.

[0277] 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).

[0278] 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.

[0279] In some embodiments, based on FIG. 6 , FIG. 7 , FIG. 9 , or FIG. 11 , the wireless communication method provided in the embodiment of the present application further includes:

[0280] The terminal device sends fourth information, where the fourth information is used to indicate one or more of the following capabilities of the terminal device:

[0281] 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;

[0282] one or more fourth mobility events, where the fourth mobility event is a mobility event predicted by the one or more first measurement results;

[0283] a fifth number, where the fifth number is a maximum number of cells supported for measurement by the terminal device on one or more carriers;

[0284] a sixth number, where the sixth number is a maximum number of spatial filters supported for measurement by the terminal device on one or more carriers;

[0285] a seventh quantity, where the seventh quantity is the quantity at the first moment supported by the terminal device on one or more carriers;

[0286] an eighth quantity, where the eighth quantity is the quantity of the second set supported by the terminal device on one or more carriers, where the first set includes one or more predicted resources at the second moment;

[0287] A ninth quantity, the ninth quantity being the number of second moments supported by the terminal device on one or more carriers.

[0288] In some embodiments, based on FIG. 8 , FIG. 10 , or FIG. 12 , the wireless communication method provided in the embodiment of the present application further includes:

[0289] The network device receives fourth information, where the fourth information is used to indicate one or more of the following capabilities of the terminal device:

[0290] 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;

[0291] one or more fourth mobility events, where the fourth mobility event is a mobility event predicted by the one or more first measurement results;

[0292] a fifth number, where the fifth number is a maximum number of cells supported for measurement by the terminal device on one or more carriers;

[0293] a sixth number, where the sixth number is a maximum number of spatial filters supported for measurement by the terminal device on one or more carriers;

[0294] a seventh quantity, where the seventh quantity is the quantity at the first moment supported by the terminal device on one or more carriers;

[0295] an eighth quantity, where the eighth quantity is the quantity of the second set supported by the terminal device on one or more carriers, where the first set includes one or more predicted resources at the second moment;

[0296] A ninth quantity, the ninth quantity being the number of second moments supported by the terminal device on one or more carriers.

[0297] In an embodiment of the present application, the terminal device reports the time domain measurement capability and time domain prediction capability supported by the terminal device to the network device based on the fourth information, wherein the measurement and prediction capability may include cell level and / or spatial filter level.

[0298] Here, the first mobility event, the second mobility event, the third mobility event, and the fourth mobility event are described:

[0299] The first mobility event is a mobility event predicted by the terminal device based on one or more first measurement results;

[0300] The second mobility event is a reported mobility event predicted by the terminal device based on one or more first measurement results;

[0301] 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;

[0302] The fourth mobility event is a mobility event that the terminal device supports prediction.

[0303] Optionally, the fourth information includes fourth indication information, and the fourth indication information is used to indicate whether the terminal device supports time domain measurement and? or time domain prediction. If the fourth indication information indicates that the terminal device supports time domain measurement of the one or more first measurement results, and supports time domain 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 time domain measurement of the one or more first measurement results, and supports time domain prediction of the first prediction information based on the one or more first measurement results.

[0304] 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.

[0305] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG13 , including:

[0306] S1301. The terminal device sends one or more first measurement results, where the one or more first measurement results include a first measurement result corresponding to each first moment in a second number of first moments of a first number of first cells, where the first measurement result is a measurement result obtained by measuring the first cell, the first moment is a historical moment, the first number is greater than or equal to 1, and the second number is greater than or equal to 1.

[0307] The one or more first measurement results are used to predict first prediction information, and the first prediction information is related to one or more first prediction results. The one or more first prediction results include a first prediction result corresponding to each second moment of a third number of second cells in a fourth number of second moments. The first prediction result is a measurement result of the second cell predicted based on the one or more first measurement results. The second moment is a future moment. The third number is greater than or equal to 1, and the fourth number is greater than or equal to 1.

[0308] An embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG14 , including:

[0309] S1401. A network device receives one or more first measurement results, where the one or more first measurement results include first measurement results corresponding to each first moment in a second number of first moments of a first number of first cells, the first measurement results being measurement results obtained by measuring the first cells, the first moment being a historical moment, the first number being greater than or equal to 1, and the second number being greater than or equal to 1.

[0310] S1402. 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. The one or more first prediction results include a first prediction result corresponding to each second moment in a fourth number of second moments of a third number of second cells. The first prediction result is a measurement result of the second cell predicted based on the one or more first measurement results. The second moment is a future moment. The third number is greater than or equal to 1, and the fourth number is greater than or equal to 1.

[0311] The terminal device measures the first number of first cells at each first moment in the second first moment, and obtains the first number*second number of first measurement results.

[0312] It can be understood that, for a first cell at a first moment, 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.

[0313] 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.

[0314] 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.

[0315] The measurement resources of the first cell may be CSI-RS resources and / or SSB resources.

[0316] The terminal device determines the first measurement results of the first number of first cells at each moment in the second number of first moments, that is, after the terminal device determines the first measurement results of the first number * the second number, the first measurement results of the first number * the second number are reported to the network device, so that the network device predicts the first prediction information based on the first measurement results of the first number * the second number.

[0317] The first measurement results of the first number of first cells at the second time of the second number 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.

[0318] The network device receives a first number of first measurement results for a first cell at a second number of second moments, and predicts first prediction information based on the first number of measurement results times the second 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.

[0319] The first prediction result is the measurement result of the second cell at the second moment predicted based on the third number * the fourth number of first measurement results. The first number * the second number of first measurement results can be used to predict the first prediction result of the third number of second cells at each of the fourth number of second moments, i.e., the third number * the fourth number of first prediction results. It is understood that the second moment is a future moment that has not yet occurred, and the first prediction result is the measurement result of the second cell at the second moment predicted or inferred based on the N * K first measurement results.

[0320] 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, that is, the first number of first cells and the third number of second cells may include the same cell or may not include the same cell.

[0321] In one example, a network device obtains first prediction information related to prediction results of cell 1, cell 2, and cell 3 at future time 1 and future time 2 based on measurement results of cell 1, cell 2, and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 1, cell 2, and cell 3 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2, and cell 3 at historical time 1 and historical time 2.

[0322] In one example, the network device obtains first prediction information related to the prediction results of cell 4 and cell 5 at future time 1 and future time 2 based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 4 and cell 5 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2.

[0323] In one example, the network device obtains first prediction information related to the prediction results of cell 3 and cell 4 at future time 1 and future time 2 based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2, wherein the prediction results of cell 3 and cell 4 at future time 1 and future time 2 are predicted based on the measurement results of cell 1, cell 2 and cell 3 at historical time 1 and historical time 2.

[0324] In some embodiments, a second prediction model is deployed in the network device. The second 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 an RNN). The network device inputs the first measurement results of the first number of first cells at the second number of historical moments into the second prediction model to obtain first prediction information output by the second prediction model.

[0325] 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.

[0326] In an embodiment of the present application, the network device predicts first prediction information related to the prediction result at a future moment based on the measurement result at a historical moment, thereby realizing time domain prediction of the measurement result.

[0327] In the wireless communication method provided by an embodiment of the present application, a network device determines first prediction information related to one or more predicted first prediction results based on the first measurement results of a first number of first cells at each historical moment in a second number of historical moments, wherein the one or more first prediction results include the prediction results of a third number of second cells at each future moment in a fourth number of future moments, and the first or more first prediction results are measurement results predicted based on the one or more first measurement results. Thus, when one or more first cells are measured at a historical moment, first prediction information related to the measurement results of one or more second cells at a future moment is predicted, thereby reducing the overhead of the reference signal used for cell measurement and preparing a response method in advance based on the first prediction information, thereby reducing the delay and other adverse effects caused by mobility.

[0328] In some embodiments, the first prediction information includes one or more of the following:

[0329] 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;

[0330] second indication information, where the second indication information is used to indicate an event type of the first mobility event that occurred;

[0331] First information indicates a first prediction result of the occurrence of the first mobility event.

[0332] In the embodiment of the present application, the first indication information may be used to indicate whether one or more first mobility events occur at the second moment in the terminal device.

[0333] 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.

[0334] In this embodiment of the present application, first measurement results of a first number of first cells at a second number of first moments are used to predict first prediction results of a third number of second cells at a fourth number of second moments. For each second moment in the fourth number of second moments, whether a first mobility event occurs at the second moment is determined based on the first prediction results of the third number of second cells at the second moment.

[0335] It can be understood that the first indication information may be used to indicate whether the first mobility event occurs at the fourth number of second moments.

[0336] 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.

[0337] 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.

[0338] At a second moment, one or more first mobility events may not occur or may occur.

[0339] In some embodiments, the event types of the first mobility events occurring at different second moments are the same or different.

[0340] It is understandable that in the embodiment of the present application, the first mobility event that occurs may be a mobility event that may occur at all or part of the second moments in the predicted fourth number of second moments.

[0341] The mobility event in the embodiment of the present application is an event related to the mobility of the terminal device that may occur at the second moment based on the prediction of the third number of first moments. Therefore, the mobility event in the embodiment of the present application can be understood as a mobility event in the time domain.

[0342] In some embodiments, the one or more first mobility events include one or more of the following first events:

[0343] 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 the predicted link performance of the serving cell is better than a first threshold;

[0344] First event B: the one or more second cells include a serving cell, and the predicted link performance of the serving cell is weaker than a second threshold;

[0345] First event C: the one or more second cells include a candidate cell and a serving cell, the predicted link performance of the candidate cell is better than the first link performance, and the first link performance is the predicted link performance of the serving cell plus a first offset;

[0346] First event D: the one or more second cells include a candidate cell, and the predicted link performance of the candidate cell is better than a third threshold;

[0347] First event E: the one or more second cells include a candidate cell and a serving cell, the predicted link performance of the serving cell is weaker than a fourth threshold, and the predicted link performance of the candidate cell is better than a fifth threshold;

[0348] First event F: the one or more second cells include a candidate cell, and the predicted interference of the candidate cell is stronger than a first interference threshold.

[0349] 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.

[0350] At the second moment, the network device predicts, based on the one or more first measurement results, that the one or more first mobility events occurring at the second moment include one or more of first events A to first events F.

[0351] 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.

[0352] In the embodiment of the present application, the link performance of a cell may be represented by one or more parameters representing the link quality of the cell, including L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR.

[0353] In some embodiments, the one or more first mobility events include one or more of the following second events:

[0354] Second event A: the one or more second cells corresponding to the one or more first mobility events include a serving cell, and the predicted performance of a serving space filter of the serving cell is better than a sixth threshold;

[0355] Second event B: the one or more second cells include a serving cell, and the predicted performance of the serving spatial filter of the serving cell is weaker than a seventh threshold;

[0356] Second event C: the one or more second cells include a candidate cell and a serving cell, and the predicted performance of the candidate spatial filter of the candidate cell is better than the second link performance, where the second link performance is the predicted performance of the serving spatial filter of the serving cell plus a second offset;

[0357] A second event D: the one or more second cells include a candidate cell, and the predicted performance of the candidate spatial filter of the candidate cell is better than an eighth threshold;

[0358] Second event E: the one or more second cells include a candidate cell, the predicted performance of the serving spatial filter of the serving cell is weaker than a ninth threshold, and the predicted performance of the candidate spatial filter of the candidate cell is better than a tenth threshold;

[0359] Second event F: the one or more second cells include a candidate cell, and the predicted interference of the candidate beam of the candidate cell is stronger than the second interference threshold.

[0360] 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.

[0361] 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.

[0362] For the second moment, the one or more first mobility events corresponding to the second moment predicted by the network device based on the one or more first measurement results include one or more of second events A to second events F.

[0363] 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.

[0364] 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.

[0365] 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.

[0366] In the embodiment of the present application, the multiple first mobility events determined based on the one or more first measurement results may be a first mobility event at one second moment, or may be the first mobility events at multiple second moments.

[0367] For the second moment, if the network device determines multiple first mobility events based on one or more first measurement results, the multiple first mobility events corresponding to the second moment 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.

[0368] In some embodiments, the first information includes one or more of the following: a time index, the time index being used to indicate a second moment corresponding to a corresponding mobility event; a cell index and / or a cell link quality; a cell link quality and / or a spatial filter link quality.

[0369] For the first mobility event that occurs, the first prediction information may indicate the time at which the first mobility event occurs, that is, the second time corresponding to the first mobility event.

[0370] In the embodiment of the present application, the first mobility event may be a cell-level mobility event or a spatial filter-level mobility event.

[0371] It is understandable that the first mobility event includes a cell-level first mobility event, and the first information corresponding to the cell-level first mobility event includes cell information corresponding to the first mobility event, and the cell information includes: cell index and / or cell link quality.

[0372] 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 of the spatial filter level 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.

[0373] 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:

[0374] 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;

[0375] 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.

[0376] 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.

[0377] In some embodiments, the reporting method of the one or more first measurement results includes:

[0378] Reporting method 1: The one or more first measurement results are transmitted through a second number of first reporting instances, and one first reporting instance includes a first measurement result corresponding to a first moment.

[0379] In reporting method one, a first reporting instance is used to report a first measurement result corresponding to a first moment, that is, the first instance is used to report the first measurement results of a second number of first cells measured at a first moment, and different first reporting instances are used to report the first measurement results corresponding to different first moments.

[0380] In some embodiments, the reporting method of the one or more first measurement results includes:

[0381] Reporting method 2: the one or more first measurement results are transmitted through a second reporting instance.

[0382] In reporting mode 2, the second number of first measurement results corresponding to the first moments are reported to the network device through one reporting instance, namely the second reporting instance, that is, the measurement results of the second number of historical moments are reported to the network device at one time in one reporting instance.

[0383] Compared with reporting method 1, reporting method 2 aggregates multiple reports into one report, reducing the number of reports and reporting overhead.

[0384] In some embodiments, the second reporting instance includes a second number of time indexes, where the time indexes indicate first moments corresponding to first measurement results corresponding to different first moments.

[0385] The second reporting instance includes explicit historical moment information. Here, the first measurement result corresponding to each first moment may explicitly include the time index of each first moment.

[0386] In some embodiments, the transmission method of the multiple first measurement results includes:

[0387] Transmission mode 1: Transmission is performed in a first order, where the first order is a preconfigured or predefined order at a first moment;

[0388] Transmission mode 2: Transmission is performed according to the first order and the second order, where the second order is the ordering of multiple measurement resources of a first measurement result corresponding to a first moment.

[0389] In the case of the second reporting mode, the first transmission mode or the second transmission mode may be used to report a plurality of first measurement results corresponding to the first moments in one reporting instance.

[0390] In the first transmission mode, the terminal device reports in accordance with the order of the first moments that are pre-configured or arranged, that is, the first order, and the network device determines the first moment corresponding to the received measurement result in accordance with the first order. In one example, the first order is the first first moment, the second first moment, the third first moment, ..., the second number of first moments. The terminal device first reports the first measurement result corresponding to the first first moment, and then reports the first measurement result corresponding to the second first moment, until the first measurement result corresponding to the last first moment is reported. The measurement results received by the network device are, in order: the first measurement result corresponding to the first first moment, the first measurement result corresponding to the second first moment, ..., the first measurement result corresponding to the last first moment.

[0391] When the first measurement results corresponding to each first moment in multiple first moments are transmitted in a first order, the first measurement results corresponding to each first moment include a resource index and a link quality, but may not include a time index of the first moment.

[0392] When the first measurement results corresponding to multiple first moments are transmitted according to the first order, reporting of the time index of the first moment is avoided, which reduces the reporting overhead, so that more resource indexes and corresponding link qualities can be reported.

[0393] In the second transmission mode, the terminal device not only transmits in the order of the pre-configured or arranged first moments, but also reports the first measurement result corresponding to each first moment according to the order of the measurement resources. The network then determines the first moment corresponding to the received measurement result according to the order of the pre-configured or arranged first moments, and for each first moment, also determines the measurement resource corresponding to the received measurement result according to the order of the measurement resources corresponding to the first moment. In one example, the terminal device first reports the measurement result of the measurement resource corresponding to the first first moment, and then reports the measurement result of the measurement resource corresponding to the second first moment, until the measurement result of the measurement resource corresponding to the last first moment is reported. For a first moment, there are 16 resources corresponding to it, and the link quality corresponding to the 16 measurement resources can be reported according to a specific resource order. The second order can be the order of the measurement resources corresponding to the first moment from high to low or from low to high according to the resource index.

[0394] When multiple first measurement results are transmitted in a first order and a second order, each first measurement result includes link quality but may not include a time index and a resource index for the first time. When multiple first measurement results are transmitted in a first order and a second order, the reporting overhead of resource index usage can be further reduced.

[0395] 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 time index of the first moment.

[0396] In some embodiments, the second order is determined based on a resource index and / or a resource type of the measured resource.

[0397] For the second order, the measured resources can be ordered from low to high (or from high to low) according to their resource index, the order can be set between different resource types, or the resource type can be determined first and then different resources corresponding to the same resource type are sorted according to the resource index.

[0398] In one example, the L1-RSRP of CSI-RS#0 is arranged first, and the L1-RSRP of CSI-RS#0 is arranged behind it.

[0399] In one example, when the measurement resources include both SSB resources and CSI-RS resources, it can be assumed that the UE reports the measurement results of one resource first, and then reports the measurement results of the other resource. For example, the UE reports the link quality corresponding to the SSB resource first, and then reports the link quality corresponding to the CSI-RS resource.

[0400] In the embodiment of the present application, when multiple first measurement results are reported, they may be reported based on a differential manner, or the first measurement result itself may be reported.

[0401] In some embodiments, based on FIG13 , an embodiment of the present application further provides a wireless communication method, as shown in FIG15 , including:

[0402] S1501. The terminal device receives fifth information, where the fifth information is used to indicate a target cell and / or a target spatial filter corresponding to each second moment in the fourth number of second moments.

[0403] In some embodiments, based on FIG14 , an embodiment of the present application further provides a wireless communication method, as shown in FIG16 , including:

[0404] S1601. The network device sends fifth information, where the fifth information is used to indicate a target cell and / or a target spatial filter corresponding to each second moment in the fourth number of second moments.

[0405] After determining the first prediction information, the network device determines fifth information based on or without the second information in response to the first prediction information, and transmits the fifth information to the terminal device. The fifth information indicates the target cell and / or target spatial filter corresponding to each second moment in the fourth quantity. It is understood that the fifth information may be related to or unrelated to the second information.

[0406] Optionally, the network device sends the fifth information to the terminal device through the CSC.

[0407] Optionally, the cell switching command itself has a MAC CE bearer, which includes at least a TCI state ID and a candidate cell index (candidate cell index), wherein the TCI state ID is used to indicate the candidate beam and the candidate cell index is used to indicate the target cell.

[0408] 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.

[0409] The fifth information may be carried in one or more cell switching commands, so that the target cell and / or target spatial filter corresponding to each second moment in the fourth number of second moments is carried in one or more cell switching commands.

[0410] In some embodiments, the fifth information is carried on a cell switching command.

[0411] The network device uses a cell switching command to indicate target cells and / or target spatial filters for a fourth number of second moments in the future to the terminal device. The terminal device determines the target cells and / or target spatial filters for the fourth number of second moments based on the cell switching command.

[0412] Understandably, the cell switching command may include up to a fourth number (F) of TCI state groups. For example, the fth TCI state group corresponds to the indication information of the cell and / or beam at the fth moment. The terminal device sequentially uses multiple TCI states indicated by the network device at different second moments.

[0413] Each TCI state group can contain one or more TCI states. When the UE operates in the Joint UL and DL TCI state mode, a joint TCI state can indicate both uplink and downlink QCL information. When the UE operates in the Separate UL and DL TCI state mode, a separate uplink and downlink TCI state can indicate uplink and downlink QCL information respectively.

[0414] In the embodiment of the present application, for the second moment, the target cell and / or target filter indicated by the fifth information may have been measured by the terminal device or may not have been measured by the terminal device.

[0415] In some embodiments, if the target cell and / or target spatial filter indicated by the fifth information includes a target cell and / or target spatial filter that has not been measured, the fifth information is also used to indicate a first measurement resource, which is used for measuring the target cell and / or target spatial filter that has not been measured and / or reporting the measurement results.

[0416] 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. The first measurement resources may include a set of CSI-RS resources and / or SSB resources.

[0417] 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.

[0418] 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.

[0419] In some embodiments, based on FIG. 13 or FIG. 15 , an embodiment of the present application provides a wireless communication method, applied to a terminal device, as shown in FIG. 17 , including:

[0420] S1701. The terminal device receives second configuration information, where the second configuration information is used to configure one or more first sets, where the one or more first sets include measurement resources of the first number of first cells at the second number of first moments.

[0421] In some embodiments, based on FIG. 14 or FIG. 16 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG. 18 , including:

[0422] S1801. The network device sends second configuration information, where the second configuration information is used to configure one or more first sets, where the one or more first sets include measurement resources of the first number of first cells at the second number of first moments.

[0423] The first set can be called the measurement set and can be expressed as Set B n，k (1<=n<=N, 1<=k<=K), N is less than or equal to the first number, and K is equal to the second number. In one example, N is the first number, and K is the second number.

[0424] In some embodiments, one of the first sets includes measurement resources of one or more first cells at one or more first moments.

[0425] Optionally, a first set includes measurement resources of a first cell at multiple first moments.

[0426] In an example, a first set includes measurement resources of a first cell at a second number of first time instants.

[0427] Optionally, a first set includes measurement resources of multiple first cells at a first moment.

[0428] In an example, a first set includes measurement resources of a first number of first cells at a first moment.

[0429] In one example, a first set includes measurement resources of a first cell at a first moment, and the first set is applied to a second number of first moments. In this case, the measurement resources of the first cell at different first moments are the same.

[0430] In some embodiments, the second configuration information is further used to configure one or more of the following:

[0431] A third uplink resource is used for reporting the one or more first measurement results.

[0432] The third uplink resource is the resource used by the terminal device to report the first measurement result.

[0433] In some embodiments, based on FIG. 13 , FIG. 15 , or FIG. 17 , the wireless communication method provided in the embodiment of the present application further includes:

[0434] The terminal device sends sixth information, where the sixth information is used to indicate one or more of the following capabilities of the terminal device:

[0435] whether the terminal device supports measurement of the one or more first measurement results;

[0436] a fifth number, where the fifth number is a maximum number of cells supported for measurement by the terminal device on one or more carriers;

[0437] a sixth number, where the sixth number is a maximum number of spatial filters supported for measurement by the terminal device on one or more carriers;

[0438] A seventh quantity, the seventh quantity being the quantity at the first moment supported by the terminal device on one or more carriers.

[0439] In some embodiments, based on FIG. 14 , FIG. 16 , or FIG. 18 , the wireless communication method provided in the embodiment of the present application further includes:

[0440] The network device receives sixth information, where the sixth information is used to indicate one or more of the following capabilities of the terminal device:

[0441] whether the terminal device supports measurement of the one or more first measurement results;

[0442] a fifth number, where the fifth number is a maximum number of cells supported for measurement by the terminal device on one or more carriers;

[0443] a sixth number, where the sixth number is a maximum number of spatial filters supported for measurement by the terminal device on one or more carriers;

[0444] A seventh quantity, the seventh quantity being the quantity at the first moment supported by the terminal device on one or more carriers.

[0445] In an embodiment of the present application, the terminal device reports the time domain measurement capability supported by the terminal device to the network device based on the sixth information, where the measurement capability may include cell level and / or spatial filter level.

[0446] Optionally, the sixth information includes sixth indication information, and the sixth indication information is used to indicate whether the terminal device supports measurement of the first number of first cells at the second number of first moments. If the sixth indication information indicates that the terminal device supports measurement of the first number of first cells at the second number of first moments, the sixth information is used to indicate other content, or the sixth information does not include the sixth indication information. When indicating other content, it is assumed that the terminal device supports measurement of the first number of first cells at the second number of first moments.

[0447] In an embodiment of the present application, after receiving the sixth information, the network device may configure the first set based on the sixth information.

[0448] The following further describes the wireless communication method provided in the embodiments of the present application.

[0449] Considering the UE's Radio Resource Management (RRM) measurement behavior at Layer 1, mobility events triggered by Layer 1 / Layer 2 measurements are defined.

[0450] It is divided into beam-level events and cell-level events.

[0451] 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.

[0452] In some embodiments, the cell-level predicted mobility event is defined as follows:

[0453] a. The link performance of the serving cell based on the prediction is better than a specific threshold;

[0454] b. The link performance of the serving cell based on the prediction is weaker than a specific threshold;

[0455] c. The link performance of the predicted candidate cell is better than that of the current serving cell (including PCell and SCell) plus an offset;

[0456] d. The link performance of the predicted candidate cell is better than a specific threshold;

[0457] e. The link performance of the serving cell based on the prediction is weaker than a specific threshold, and the link performance of the candidate cell based on the layer 1 measurement and / or prediction is better than a specific threshold;

[0458] f. The interference of the candidate cell based on the prediction is stronger than a certain threshold for the UE.

[0459] Events a to f are first events at the cell level.

[0460] The beam-level predicted mobility events are defined as follows:

[0461] 1. The performance of the serving beam of the predicted serving cell is better than a specific threshold;

[0462] 2. The performance of the serving beam of the predicted serving cell is weaker than a specific threshold;

[0463] 3. The performance of the candidate beam based on the prediction is better than the serving beam performance of the current serving cell (including PCell and SCell) plus the offset;

[0464] 4. The performance of the candidate beam based on the predicted candidate cell is better than a specific threshold;

[0465] 5. The performance of the serving beam of the serving cell based on the prediction is weaker than a specific threshold, and the performance of the candidate beam of the candidate cell based on the layer 1 measurement and / or prediction is better than a specific threshold;

[0466] 6. The interference of the candidate beams of the predicted candidate cells is stronger than a certain threshold for the UE.

[0467] Events one to six belong to the second events at the beam level.

[0468] It should be noted that since the actual measurement results can only occur in the past and present, not in the future, time domain mobility prediction can only judge future mobility events through the prediction results output by the model. This is different from spatial domain mobility prediction (which can be judged through measurement and / or prediction results).

[0469] 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.

[0470] The UE compares the mobility events defined above with the prediction results of the model to determine whether a layer 1 / layer 2 mobility event will occur in the future and which mobility event will occur. For better explanation, in one example, as shown in Figure 19, the UE moves from the current serving cell #1 to the candidate cell #2 via the candidate cell #1. During the UE's movement, the UE performs K historical measurements (assuming the model is deployed on the UE side), and the UE can predict the "measurement" results for the next F moments in advance. The "measurement" here is not the actual measurement result, but the measurement result predicted by the model, so quotation marks are added. Therefore, the technical advantage of the embodiment of the present application is that the UE has the opportunity to judge in advance whether a mobility management event will occur at any of the future F moments, and which event will occur, and decide whether to report the predicted measurement result and / or the corresponding mobility event to the NW.

[0471] 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.

[0472] Example 1: Mobility event prediction with model deployed on UE side

[0473] 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.

[0474] S1901. UE reports its capabilities.

[0475] 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 time domain measurement and / or time domain 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:

[0476] Information 1: What types of time-domain mobility events are supported by the UE-side model for prediction on one or more carriers?

[0477] Information 2: The maximum number of candidate cells that the UE supports measurement on one or more carriers;

[0478] In some embodiments, one candidate cell corresponds to one measurement set; in other embodiments, multiple candidate cells correspond to one measurement set, i.e., downlink reference signal resources from multiple candidate cells (including the serving cell) are configured into one measurement set. In some embodiments, a UE supports a maximum number of measurement sets on a carrier. In each measurement set, a maximum number of downlink measurement resources (e.g., CSI-RS resources and / or SSB resources) are measured.

[0479] Information 3: On one or more carriers, the UE supports the measurement of a maximum number of candidate beams.

[0480] Different candidate beams may come from different candidate cells.

[0481] Information 4: On one or more carriers, the UE supports a maximum number of prediction sets.

[0482] In some embodiments, one candidate cell corresponds to one prediction set; in other embodiments, multiple candidate cells correspond to one prediction set. In each prediction set, a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources) are predicted.

[0483] Information 5: On one or more carriers, the UE supports a maximum number of future time predictions.

[0484] S1902. The NW configures measurement resources and prediction resources.

[0485] Based on the UE's capability report, the NW configures resources for the UE, including but not limited to the following:

[0486] The NW configures the measurement set Set B of candidate cells for the UE (the candidate cells include the current serving cell and one or more other cells) n，k (1<=n<=N, 1<=k<=K) and prediction set Set A m，f (1<=m<=M, 1<=f<=F).

[0487] In one example, a candidate cell corresponds to a measurement set at a historical moment. In this case, k is the time domain index of the measurement set, meaning the UE needs to measure a total of K historical moments as model input. In another example, a cell corresponds to a prediction set at a future moment. In this case, f is the time domain index of the prediction set, meaning the model can predict "measurement" results for F future moments based on historical measurements.

[0488] In some embodiments, for cell-level mobility events, one candidate cell may correspond to one measurement set Set B. n,k , k ranges from 1 to N. In this case, the measurement set is applied to each moment of candidate cell n, that is, the measurement set corresponding to each moment is the same, and N is the total number of candidate cell measurement sets. Each measurement set contains one or more downlink measurement resources of the candidate cell, that is, CSI-RS resources and / or SSB resources. In addition, the prediction set Set A m,f It may also include one or more downlink measurement resources.

[0489] In one example, as shown in FIG20 , the serving cell of the UE is cell #1, and the candidate cells include cell #2 and cell #3. The NW configures one or more LTM event types that can be predicted for the UE, and the UE trajectory is cell #1, cell #2, and cell #3. The historical measurement instance predicts the future prediction instance, and the historical measurement instance includes the measurement results corresponding to historical time 1 to historical time K. The measurement result corresponding to historical time 1 includes the measurement results of the following measurement sets: Set B 1，1 , SetB 2，1 ,…,SetB N，1 , the measurement results corresponding to historical moment 2 include the measurement results of the following measurement sets: SetB 1，2 , SetB 2，2 ,…,SetB N，2 , and so on, the measurement results corresponding to the historical moment K include the measurement results of the following measurement sets: SetB 1，K , SetB 2，K ,…,SetB N，K , the future prediction instance includes: the prediction results corresponding to the future time 1 to the future time F, wherein the prediction result corresponding to the future time 1 includes the prediction results of the following prediction sets: SetA 1，1 , SetA 2，1 ,…,SetA M，1 , the prediction results corresponding to the future time 2 include the prediction results of the following prediction sets: SetA 1，2 , SetA 2，2 ,…,SetA M，2 , and so on, the prediction results corresponding to the future time F include the prediction results of the following prediction sets: SetA 1，F , SetA 2，F ,…,SetA M，F .

[0490] In some embodiments, for cell-level mobility events, one candidate cell corresponds to one measurement set Set B. n，k (1<=n<=N, 1<=k<=K), 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，f It may also include one or more downlink measurement resources.

[0491] The NW configures one or more mobility event types that can be predicted for the UE.

[0492] 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).

[0493] In the embodiments of the present application, we consider the prediction of mobility events in the time domain. In some embodiments, a candidate cell may correspond to a measurement set and a prediction set. Set B n，k and Set A m，f Similarly, the model has no spatial domain prediction, only time domain prediction. If Set B n，k It is Set A m，f A subset of , which includes both time domain prediction and spatial domain prediction.

[0494] In some other embodiments, Set B n，k With Set A m，f Can also be different, for example, Set B n，k The SSB-based wide beams included in Set A (fewer in number) m，f In some embodiments, a candidate cell may correspond to only one prediction set but no corresponding measurement set. The model can 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, at future times.

[0495] The configuration signaling used by the NW may be RRC signaling.

[0496] S1903: The UE infers a mobility event through a model.

[0497] When the UE completes the measurement, it completes the measurement of Set B. n，k The model uses historical measurements (1 <= n <= N, 1 <= k <= K) as input, and the model performs inference. The model predicts the measurement results at future moments and determines whether a mobility event has occurred.

[0498] The prediction result includes one or more combinations of the following inferences. The inference result should be from the prediction set Set A m，f Select from (1<=m<=M, 1<=f<=F).

[0499] Whether a mobility event configured, indicated, or preset by the NW occurs.

[0500] If a mobility event occurs, which mobility event (i.e., event type) and other important event information:

[0501] The future moment corresponding to the event is the value of the time domain index f;

[0502] Serving cell information, and / or serving beam information, and / or serving beam link quality corresponding to the event;

[0503] The candidate cell information, and / or candidate beam information, and / or candidate beam link quality corresponding to the event.

[0504] The relationship between the input and output of the model 2101 can be shown in FIG21A. The input of the model 2101 includes: set B 1，1 (SetB 1，1 ), Set B 2，1 (SetB 2，1 ),…, set B N，1 (SetB N，1 ), Set B 1，2 (SetB 1，2 ), ... set B N、K (SetB N、K ), the model output includes: LTM event type (LTM event type), future time index f, candidate cell information, and serving cell information, wherein the candidate cell information includes: candidate cell 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: serving cell 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 model can directly predict LTM events.

[0505] In some other embodiments, the model may predict measurement results in the future time domain, such as the index of candidate cells (including the serving cell) and / or the index of candidate beams (including the current serving beam) and link quality. The UE then determines whether an LTM event has occurred based on predefined LTM events.

[0506] The temporal relationship between the input and output of the model can be shown in FIG21B . The prediction information of the future moment is obtained based on the measurement results of the input historical moment. The measurement results of the input historical moment include the measurement results corresponding to historical moment 1 to historical moment K. The measurement results corresponding to historical moment 1 include the measurement results of the following measurement sets: Set B 1，1 , SetB 2，1 ,…,SetB N，1 , the measurement results corresponding to historical moment 2 include the measurement results of the following measurement sets: SetB 1，2 , SetB 2，2 ,…,SetB N，2 , and so on, the measurement results corresponding to the historical moment K include the measurement results of the following measurement sets: SetB 1，K , SetB 2，K ,…,SetB N，K For the future time 1, the predicted measurement result is the prediction result of the following prediction set: SetA 1，1 , SetA 2，1 ,…,SetA M，1 ; For the future time 2, the predicted measurement results are the prediction results of the following prediction set: SetA 1，2 , SetA 2，2 ,…,SetA M，2 ; Similarly, for the future time F, the predicted measurement results are the prediction results of the following prediction set: SetA 1，F , SetA 2，F ,…,SetA M，F For the future time when a mobility event occurs, the output prediction information of the future time includes: whether a mobility event occurs, the time type of the mobility event, the candidate cell or beam index and the link quality.

[0507] The prediction information is determined based on the prediction results. As shown in FIG21B , the prediction results include: prediction results corresponding to future time 1 to future time F, wherein the prediction result corresponding to future time 1 includes the prediction results of the following prediction sets: Set A 1，1 , SetA 2，1 ,…,SetA M，1 , the prediction results corresponding to the future time 2 include the prediction results of the following prediction sets: SetA 1，2 , SetA 2，2 ,…,SetA M，2 , and so on, the prediction results corresponding to the future time F include the prediction results of the following prediction sets: SetA 1，F , SetA 2，F ,…,SetA M，F .

[0508] S1904: The UE reports a mobility event.

[0509] 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 link performance of the UE's current serving cell at future time 2 will be better than a specific threshold (event A) and will maintain 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.

[0510] 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 at future time 3 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.

[0511] The report content may include at least one of the following information:

[0512] Predict the type of mobility event that is about to occur (within the next F moments); the future moment index of the mobility event, i.e., the time instance, where the granularity of the time domain can be millimeter level, or slot level, etc.; the service cell information corresponding to the event; where the service cell information may include: service cell index, and / or service beam information, and / or service beam link quality; the candidate cell information corresponding to the event; where the candidate cell information may include: candidate cell index, and / or candidate beam information, and / or candidate beam link quality.

[0513] For reporting predicted mobility events, the UE can use control signaling from the physical layer or higher layers. In some embodiments, when the model infers that a pre-set mobility event has occurred, the UE decides to report. The reporting resource may be the UCI carried by the PUCCH or the PUSCH scheduled via the SR request. The UCI belongs to the control signaling of the physical layer. In other embodiments, the UE may use the SR to request the MAC CE carried by the PUSCH scheduled. The MAC CE belongs to the control signaling used by the MAC layer.

[0514] When the model predicts that one or more mobility events will occur within F time periods in the future, the UE reports the information of one or more mobility events at F time periods to the NW in a single report. It should be noted that each reported mobility event can have different reporting content. For example, it is possible that at the first time period, f = 1, the model predicts that mobility event a will occur; at the second time period, f = 2, the model predicts that mobility event b will occur; at the third time period, f = 3, the model predicts that no mobility event will occur. And so on.

[0515] Taking the UCI reporting format as an example, the mobility event information reported by the UE at F moments is shown in Table 1. It should be noted that when no event occurs at a certain moment (based on the prediction results of the model), the UE may not report the information corresponding to that moment, so the "if reported" restriction is used in this table.

[0516] Table 1. Example of reporting mobility events at F future moments

[0517] For MAC CE reporting, the 8-bit per byte format commonly used in MAC CE can be used, using the same content as UCI reporting. However, it is often difficult to fully traverse and accurately predict the specific MAC CE format. Here, we only try to protect the reporting content, not the specific MAC CE format.

[0518] S1905. The NW indicates mobility information to the UE.

[0519] Here, mobility information can be understood as the third information. The NW can issue a Cell Switch Command (CSC) to the UE. This command itself is carried by a MAC CE, which contains at least a TCI state ID and a candidate cell index, indicating a candidate beam and candidate cell, respectively. After receiving the cell switch command, the UE completes the cell switch operation within a specified time.

[0520] For mobility events predicted in the time domain based on AI / ML in the embodiments of the present application, to avoid indicating each of the next F moments one by one, the NW can use a cell handover command to indicate mobility operation information for the next F moments to the UE. In some embodiments, the cell handover command can include up to F groups of TCI state(s). For example, the fth group of TCI state(s) corresponds to the indication information of the cell and / or beam at the fth moment. The UE sequentially uses the multiple groups of TCI state(s) indicated by the NW at different moments.

[0521] It should be noted that each group of TCI states can contain one or more TCI states. When the UE operates in the Joint UL and DL TCI state mode, a joint TCI state can indicate uplink and downlink QCL information; when the UE operates in the Separate UL and DL TCI state mode, a separate uplink and downlink TCI state can indicate uplink and downlink QCL information respectively.

[0522] The UE has not previously measured the downlink reference signals included in the TCI state(s) indicated by the NW. In this case, an additional set of measurement resources (such as a set of CSI-RS resources and / or SSB resources) can be indicated in the cell handover command for each set of indicated TCI state(s). The UE can complete the measurement and / or reporting of the target cell and / or target beam using the indicated resources.

[0523] 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.

[0524] Example 2: Mobility event prediction with model deployed on the NW side

[0525] If the model is deployed on the NW side, the wireless communication method provided in the embodiment of the present application, as shown in FIG22 , includes S2201 to S2205 .

[0526] S2201. UE reports its capabilities.

[0527] The UE reports its supported mobility event (including cell-level and beam-level) measurement capabilities. Specifically, the UE first informs the NW whether it supports time 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:

[0528] Information 1: The maximum number of candidate cells that the UE supports measurement on one or more carriers;

[0529] 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.

[0530] In some embodiments, on a carrier, the UE supports a maximum number of measurement sets for measurement. In each measurement set, the UE measures a maximum number of downlink measurement resources (such as CSI-RS resources and / or SSB resources).

[0531] Information 3: On one or more carriers, the UE supports the measurement of a maximum number of candidate beams.

[0532] Different candidate beams may come from different candidate cells.

[0533] Information 4: On one or more carriers, the UE supports a maximum number of historical measurements.

[0534] 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.

[0535] S2202: The NW configures measurement resources.

[0536] Based on the UE's capability report, the NW configures resources for the UE, including but not limited to the following:

[0537] Resource 1, NW configures the measurement set Set B of the candidate cell (including the serving cell) for the UE n，f (1<=n<=N, 1<=n<=K). Where k is the time domain index of the measurement set, that is, the UE needs to measure a total of K historical moments to infer the model.

[0538] In some embodiments, for cell-level mobility events, one candidate cell corresponds to one measurement set Set B. n,k , and the measurement sets at different historical moments are the same, 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, namely, CSI-RS resources and / or SSB resources.

[0539] The configuration signaling used by the NW may be RRC signaling.

[0540] 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.

[0541] S2203: The UE measures and reports the measurement result.

[0542] According to the NW configuration, the UE measures the measurement set Set B of the mobility event n，f (1<=n<=N, 1<=n<=K). The UE measures the data at different historical moments k and obtains measurement results.

[0543] In related technologies, the UE can only report measurement results to the NW through K reports, which has the disadvantage of requiring multiple reporting overheads.

[0544] [Corrected 21.02.2024 according to Rule 91] This embodiment of the present application proposes an enhanced method in which the UE can report the measurement results of K historical moments to the NW in one beam reporting instance. For this enhanced reporting, the carrier can be UCI (i.e., uplink control information) as shown in Table 2, or it can be reported through MAC CE signaling. This allows multiple reports to be aggregated into one report, reducing the number of reports and reporting overhead.

[0545] [Corrected 21.02.2024 in accordance with Rule 91] This reporting can use the flexible reporting format shown in Table 2, where the report includes explicit historical time information, such as the measurement time index k, which is represented as the time instance index in this table. In addition, the index of the measurement resource, i.e., the CRI or SSBRI, can also be reported, providing greater flexibility in the UE's reporting content.

[0546] Table 2. Measurement result reporting example

[0547] In other embodiments, because measurement results are reported in a single reporting instance, a fixed order can be agreed upon. As shown in Table 3, the UE sequentially reports N measurement results for the first historical moment, N measurement results for the second historical moment, and so on, up to N measurement results for the last historical moment K. This technical advantage is that the overhead of reporting historical moment indexes is reduced.

[0548] Table 3. Example of measurement result reporting

[0549] For simplicity, it is assumed here that each measurement set contains the same reference signal resources. However, in a wider range of embodiments, the number of reference signal resources in each measurement set is often different.

[0550] In Table 4, in addition to reporting in a fixed time domain measurement order, it is also possible to report in a fixed resource index at each measurement moment. Because the measurement resources are all configured by the NW, the UE can directly report the measurement quality, such as L1-RSRP, in a fixed order. The fixed order can be that the measurement resources are reported according to the link quality corresponding to their resource indexes from low to high (or from high to low). For example, the L1-RSRP of CSI-RS#0 needs to be placed in the front, and the L1-RSRP of CSI-RS#0 is placed on its side. When the NW configures SSB resources and CSI-RS resources at the same time, it can be assumed that the UE reports one of the resources first (for example, reports the link quality corresponding to the SSB resources first), and then reports the link quality corresponding to the CSI-RS resources.

[0551] Table 4. Example of measurement result reporting

[0552] It should be noted that, since there is no resource index, there is no resource index corresponding to the strongest L1-RSRP for differential reporting. Therefore, in this case, non-differential L1-RSRP reporting can be considered.

[0553] In some other embodiments, the uplink signaling may be MAC CE or RRC signaling.

[0554] S2204. NW infers mobility events through the model.

[0555] The NW side model performs similar inference as the UE side model. Please refer to the description of S1904 here.

[0556] S2205. The NW indicates mobility information to the UE.

[0557] The description of S2205 is the same as that of S1905 and is not repeated here.
