[0068] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0069] FIG1 is a schematic diagram of an application scenario of an embodiment of the present application.

[0070] 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.

[0071] 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.

[0072] 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 (eg, UE) located within the coverage area.

[0074] 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.

[0075] For example, the terminal device 110 may refer to an access terminal, user equipment (UE), a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user apparatus.

[0076] The terminal device 110 can be used for device-to-device (D2D) communication.

[0077] The wireless communication system 100 may further include a core network device 130 for communicating with the base station. The core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device of an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions that can be implemented by SMF and PGW-C. During the network evolution process, the above-mentioned core network device may also be called other names, or a new network entity may be formed by dividing the functions of the core network, which is not limited in the embodiments of the present application.

Optionally, the wireless communication system 100 may include multiple base station devices and each base station may include other numbers of terminal devices within its coverage area, which is not limited in this embodiment of the present application.

[0081] 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.

[0082] 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.

[0083] NR standardizes the beam management mechanism.

[0084] Beam management includes beam-related measurements and reporting, as well as beam indication by the network (NW) based on UE reports. Beam measurement is based on periodic, semi-persistent, and aperiodic downlink reference signals. The downlink reference signal is the Channel State Information-Reference Signal (CSI-RS) or the Synchronization Signal and PBCH Block (SSB). Beam reporting is associated with measurement resources and includes periodic beam reporting, such as using the Physical Uplink Control Channel (PUCCH) resources for reporting; beam reporting can also be semi-persistent reporting, such as using PUCCH or PUSCH resources for reporting. Semi-persistent reporting can be activated or deactivated using the Media Access Control-Control Element (MAC CE); beam reporting can also be aperiodic reporting, such as using PUSCH resources, triggered based on DCI sent by the NW.

[0085] After the NW receives the UE's beam report, it can provide beam indication to the UE, that is, indicating a unified transmission configuration indication (TCI) state (Single TRP) or a group of TCI states (multi-TRP). The TCI state can be a legacy TCI or a unified TCI state. Regardless of the type of TCI state, it can contain a downlink reference signal (applicable to downlink and uplink transmission) or an uplink reference signal (applicable only to uplink transmission). The Quasi Co-Location (QCL) type of this reference signal is Type D, which is specifically used to indicate the QCL relationship between different reference signals, that is, the beam relationship.

[0086] In summary, the traditional beam management mechanism described above is based on UE measurements and reporting, and NW instructions, and is a reactive beam management mechanism. It has a certain lag in responding to real-time channel changes. Therefore, the embodiments of the present application propose a beam management mechanism based on AI / ML prediction, which is a proactive approach.

[0087] Artificial Intelligence (AI) / Machine Learning (ML) Models

[0088] 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 using 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 the activation function f to produce the output t.

[0089] A simple neural network, shown in Figure 3, consists of an input layer 301, a hidden layer 302, and an output layer 303. By using different connections, weights, and activation functions among multiple neurons, different outputs can be generated, thereby fitting the mapping relationship from input to output. Each node in the previous level is connected to all of its next-level nodes. This fully connected model is also called a deep neural network (DNN). This neural network (NN) model can perform beam prediction in the spatial domain.

[0090] A NN model can be trained and obtained through the process of dataset construction, training, validation, 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 on 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.

[0091] In the embodiments of this application, the term "beam (pair)" refers to a "beam" or "beam pair." Specifically, a beam in this embodiment can refer to a transmit beam or a receive beam, and a beam pair refers to a pair of a transmit beam and a receive beam. In the protocol, transmit / receive spatial filters are generally used instead of transmit / receive beams, meaning that the term "beam" and "spatial filter" are interchangeable.

[0092] For a model, its output can be understood as inference or prediction. In the embodiments of the present application, inference and prediction have the same meaning and can be interchangeable.

[0093] In the beam management process of related technologies, in order to obtain the best or preferred beam in real time for data or control transmission, the NW may configure or activate frequent periodic or semi-persistent beam reporting (for example, the best N beams and their corresponding L1-RSRP) or trigger frequent aperiodic beam reporting. However, this will undoubtedly lead to large uplink reporting overhead and control signaling overhead. At the same time, if the configured beam reporting is less frequent, the NW may not always obtain the "best / preferred" beam because the UE's beam report may be outdated, which will lead to performance degradation.

[0094] The above is a major work content of MIMO standardization. In the description of this part of the work, the focus of standardization is on UE-initialized or event-driven beam reporting. It includes the uplink signaling content used for beam reporting, or the medium used to carry it. However, the disadvantage is that in order to observe predefined beam events, the UE still needs a large number of measurements, because the UE cannot simultaneously measure multiple simulated beams within a time unit (such as an OFDM symbol). Therefore, for the UE, a large number of measurements bring a lot of resource overhead and delay overhead.

[0095] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0096] The wireless communication method provided in the embodiment of the present application is applied to a terminal device, as shown in FIG4 , and includes:

[0097] S401. The terminal device predicts first prediction information based on one or more first measurement results, where the first measurement result is a measurement result obtained by measuring a first spatial filter. The first prediction information is related to the one or more first prediction results, where the first prediction result is a measurement result of a second spatial filter predicted based on the one or more first measurement results.

[0098] The terminal device measures a first number of first spatial filters to obtain a measurement result of each of the first spatial filters in the first number of first spatial filters, that is, obtains a first number of first measurement results. The first number is an integer greater than or equal to 1. It is understandable that one measurement resource corresponds to one spatial filter.

[0099] 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 spatial filter. The first measurement result may include: 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), signal-to-noise ratio (SNR) One or more.

[0100] The measurement resources of the first spatial filter may be Channel State Information-Reference Signal (CSI-RS) resources and / or Synchronization Signal and PBCH Block (SSB) resources.

[0101] After determining the first number of first measurement results, the terminal device predicts first prediction information based on the first number of first measurement results. The first prediction information is related to the first prediction result. It is understandable that the first prediction information is determined based on the first prediction result.

[0102] The first prediction result is a measurement result of the second spatial filter predicted based on the first number of first measurement results. The first number of first measurement results may predict one or more first prediction results, and different first prediction results in the multiple first prediction results correspond to different second spatial filters. It is understandable that the first prediction result is the measurement result of the second spatial filter, but the first prediction result is not a measurement result obtained by measuring the second spatial filter, but rather a measurement result predicted or inferred based on the first number of first measurement results.

[0103] It can be understood that the second spatial filter belongs to the first number of first spatial filters or does not belong to the first number of first spatial filters.

[0104] In one example, the terminal device obtains first prediction information related to the prediction results of beam 4 and beam 5 based on the measurement results of beam 1, beam 2 and beam 3, wherein the prediction results of beam 4 and beam 5 are predicted based on the measurement results of beam 1, beam 2 and beam 3.

[0105] In one example, the terminal device obtains first prediction information related to the prediction results of beam 3 and beam 4 based on the measurement results of beam 1, beam 2 and beam 3, wherein the prediction results of beam 3 and beam 4 are predicted based on the measurement results of beam 1, beam 2 and beam 3.

[0106] It can be understood that a beam may be a service beam or a candidate beam of the terminal device, wherein the service beam is the beam of the service cell of the terminal device, and the candidate beam may be the beam of the service cell or the beam of the candidate cell.

[0107] In some embodiments, a first prediction model is deployed in the terminal device. The first prediction model can be expressed in various forms, such as a function, a deep learning model, a neural network model (e.g., a DNN, a CNN, or a RNN). The terminal device inputs a first number of first measurement results into the first prediction model to obtain first prediction information output by the first prediction model.

[0108] In the wireless communication method provided in an embodiment of the present application, a terminal device determines first prediction information related to the predicted measurement results of one or more second spatial filters based on one or more first measurement results, thereby predicting the measurement results of one or more second spatial filters when measuring the one or more first spatial filters, and obtains the first prediction information based on the predicted measurement results of the one or more second spatial filters, thereby obtaining the first prediction information without measuring the one or more second spatial filters, thereby reducing the overhead of the reference signal used to perform spatial filter measurement.

[0109] In some embodiments, based on FIG4 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG5 , including:

[0110] S501: The terminal device sends second information to a network device, where the second information is used to indicate a second spatial filter management event, and the second spatial filter management event is the reported first spatial filter management event.

[0111] The first prediction information includes a first spatial filter management event, which is a spatial filter management event related to the first prediction result. The spatial filter management event can be understood as an event related to spatial filter management of the terminal device.

[0112] In some embodiments, based on FIG4 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG5 , including:

[0113] In some embodiments, an embodiment of the present application provides a wireless communication method, applied to a network device, as shown in FIG6 , including:

[0114] S601. A network device receives second information sent by a terminal device, where the second information is used to indicate a second spatial filter management event, where the second spatial filter management event is a reported first spatial filter management event, where the first spatial filter management event is related to a first prediction result, where the first prediction result is a measurement result of the second spatial filter predicted based on the one or more first measurement results, and where the first measurement result is a measurement result obtained by measuring the first spatial filter.

[0115] The one or more first measurement results are used by the terminal device to predict first prediction information, and the first prediction information is related to the one or more first prediction results.

[0116] The wireless communication method shown in FIG. 5 or FIG. 6 is further described below.

[0117] The terminal device determines, based on the first prediction result, that a first spatial filter management event has occurred on the terminal device, and that the first spatial filter management event needs to be reported. The terminal device then needs to report the reported first spatial filter management event to the network device. At this point, the terminal device sends second information to the network device, where the second information indicates that the reported first spatial filter management event is a second spatial filter management event.

[0118] The network device receives the second information sent by the terminal device, and determines based on the second information that a second spatial filter management event has occurred in the terminal device.

[0119] It is understandable that the terminal device may determine one or more first spatial filter management events based on the first prediction result, and all or part of the determined one or more first spatial filter management events are second spatial filter management events.

[0120] In an embodiment of the present application, if the terminal device predicts a second spatial filter management event based on one or more first measurement results, the second spatial filter management event can be reported directly to the network device without reporting the first measurement result to the network device, thereby reducing signaling overhead.

[0121] In some embodiments, the first prediction information includes one or more of the following:

[0122] first indication information, where the first indication information is used to indicate whether one or more first spatial filter management events occur, where the first spatial filter management events are related to the first prediction result;

[0123] second indication information, where the second indication information is used to indicate an event type of the first spatial filter management event that occurred;

[0124] first information of the service spatial filter corresponding to the first spatial filter management event;

[0125] first information of a candidate spatial filter corresponding to the first spatial filter management event;

[0126] a timing advance of a candidate spatial filter corresponding to the first spatial filter management event;

[0127] The first spatial filter manages power control parameters of candidate spatial filters corresponding to the event.

[0128] In an embodiment of the present application, the first indication information may be used to indicate whether one or more first spatial filter management events occur in the terminal device.

[0129] It is understandable that different values ​​of the first indication information are used to indicate that one or more first spatial filter management events have occurred, or that no first spatial filter management event has occurred.

[0130] In the embodiment of the present application, if the first prediction information includes the second indication information, the first prediction information may include the first indication information or may not include the first indication information.

[0131] In some embodiments, the one or more first spatial filter management events are spatial filter management events configured or preset by the network device. In this case, the first indication information is used to indicate whether the spatial filter management event configured or preset by the network device occurs.

[0132] If a first spatial filter management event occurs, the second indication information is used to indicate which first spatial filter management event occurred. It is understood that if multiple first spatial filter management events occur, the first prediction information includes multiple second indication information, with different second indication information indicating different event types of first spatial filter management events.

[0133] If the spatial filter corresponding to the first spatial filter management event includes a serving spatial filter, the first prediction information may include first information of the serving spatial filter corresponding to the first spatial filter management event.

[0134] If the spatial filter corresponding to the first spatial filter management event includes a candidate spatial filter, the first prediction information may include one or more of the first information, timing advance, and power control parameters of the candidate spatial filter corresponding to the first spatial filter management event. It is understood that the timing advance and power control parameters of the candidate spatial filter are only applicable to uplink channel and signal transmission.

[0135] In some embodiments, the one or more first spatial filter management events include one or more of the following events:

[0136] Event A: the one or more second spatial filters corresponding to the one or more first spatial filter management events include a serving spatial filter, and the performance of the serving spatial filter is better than a first threshold;

[0137] Event B: the one or more second spatial filters include a serving spatial filter, and performance of the serving spatial filter is weaker than a second threshold;

[0138] Event C: the one or more second spatial filters include a candidate spatial filter and a serving spatial filter of the serving cell, and performance of the candidate spatial filter of the serving cell is better than performance of the first spatial filter, where the performance of the first spatial filter is the performance of the serving spatial filter plus a first offset;

[0139] Event D: the one or more second spatial filters include a candidate spatial filter of the candidate cell and a serving spatial filter, performance of the candidate spatial filter of the candidate cell is better than performance of the second spatial filter, and the performance of the second spatial filter is the performance of the serving spatial filter plus a second offset;

[0140] Event E: the one or more second spatial filters include a candidate spatial filter of a serving cell, and performance of the candidate spatial filter of the serving cell is better than a third threshold;

[0141] Event B: the one or more second spatial filters include a candidate spatial filter of a candidate cell, and performance of the candidate spatial filter of the candidate cell is better than a fourth threshold;

[0142] Event F: the one or more second spatial filters include a serving spatial filter and a candidate spatial filter of a serving cell, performance of the serving spatial filter is weaker than a fifth threshold, and performance of the candidate spatial filter of the serving cell is better than a sixth threshold;

[0143] Event G: the one or more second spatial filters include a serving spatial filter and a candidate spatial filter of a candidate cell, performance of the serving spatial filter is weaker than a seventh threshold, and performance of the candidate spatial filter of the candidate cell is better than an eighth threshold;

[0144] Event H: the one or more second spatial filters include a service spatial filter, and performance fluctuation of the service spatial filter exceeds a first range;

[0145] Event 1: the one or more second spatial filters include a candidate spatial filter of a serving cell, and interference of the candidate spatial filter of the serving cell is stronger than a first interference threshold;

[0146] Event J: the one or more second spatial filters include a candidate spatial filter of a candidate cell, and interference of the candidate spatial filter of the candidate cell is stronger than a second interference threshold.

[0147] For the multiple threshold values ​​involved in event A to event J, the values ​​of different threshold values ​​may be the same or different.

[0148] In the embodiment of the present application, the performance of the spatial filter can be represented by one or more parameters of the spatial filter, including L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR, which represent the link quality of the cell.

[0149] It is understandable that if the second spatial filter has a first measurement result and a first prediction result, the terminal device can determine whether the first spatial filter management event occurs for the second spatial filter based on the first measurement result and / or the first prediction result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the first measurement result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the first prediction result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the result with better link performance between the first measurement result and the first prediction result of the second spatial filter.

[0150] In some embodiments, the performance fluctuations include one or more of the following:

[0151] Fluctuation parameter 1: the number of times the link quality fluctuates above the ninth threshold within the first duration;

[0152] Fluctuation parameter 2: duration during which the link quality is less than the tenth threshold within the second time period.

[0153] Fluctuation parameter 3: Ratio of the duration of link quality less than the eleventh threshold during the third duration to the total duration

[0154] For the first fluctuation parameter, the first duration is a specific duration determined by the first time window. The first waveform parameter is the number of times the link quality fluctuates above the ninth threshold within the first time window.

[0155] The number of times the link quality fluctuates on the ninth threshold may include: the number of times the link quality changes from a value greater than the ninth threshold to a value less than the ninth threshold, and / or the number of times the link quality changes from a value less than the ninth threshold to a value greater than the ninth threshold.

[0156] For the second fluctuation parameter, the second duration is a specific duration determined by the second time window. The second waveform parameter is the duration during which the link quality is lower than a specific threshold, ie, the tenth threshold, within the specific duration.

[0157] It is understandable that the duration during which the link quality is lower than the tenth threshold may be the duration of a time period during which the link quality is lower than the tenth threshold or the sum of the durations of multiple time periods.

[0158] For the third fluctuation parameter, the third duration is a specific duration determined by the third time window. The third fluctuation parameter is the ratio of the duration of the link quality being below a specific threshold, namely the eleventh threshold, to the total duration within the specific duration.

[0159] In some embodiments, the first information includes one or more of the following:

[0160] Cell index;

[0161] Spatial filter index;

[0162] Spatial filter link quality.

[0163] In the embodiment of the present application, when the spatial filter to which the first information belongs is the spatial filter of the serving cell, the first information may not include the cell index of the serving cell.

[0164] In an example, the first prediction information determined by the terminal device based on the one or more first measurement results includes one or more of the following:

[0165] The event type of event G;

[0166] Candidate beam index;

[0167] Link quality of candidate beams;

[0168] Serving beam index;

[0169] Link quality of the serving beam.

[0170] If the candidate beam comes from a non-serving cell, ie, a candidate cell, the first prediction information also includes an index of the candidate cell, such as a physical cell identifier (PCI) that is different from the serving cell.

[0171] It should be noted that after the terminal device predicts the first prediction information, it can report the first spatial filter management event indicated by the first prediction information to the network device, or it can report the first spatial filter management event used for reporting in the first spatial filter management event indicated by the first prediction information, that is, the second spatial filter management event, to the network device.

[0172] In one example, the reported spatial filter management events include: event B, event C, and event D. If the first prediction information indicates that event A has occurred, the terminal device does not send the second information, and at this time, the network device does not receive the second information.

[0173] In one example, the reported spatial filter management events include: event B, event C, and event D. If the first prediction information indicates that event B has occurred, the terminal device sends the second information, and the sent second information indicates event B.

[0174] In one example, the reported spatial filter management events include: event B, event C, and event D. The first prediction information indicates that event B and event D have occurred. The terminal device sends the second information, and the sent second information indicates event B and event D.

[0175] In some embodiments, the second spatial filter management event is:

[0176] Determined by the terminal equipment; or

[0177] Indicated by the network device; or

[0178] Predefined.

[0179] If the second spatial filter management event is determined by the terminal device, the terminal device may independently determine whether to report the first prediction result of the spatial filter management event.

[0180] If the second spatial filter management event is indicated by the network device, the terminal device reports the first prediction result of the spatial filter management event according to the configuration or instruction of the network device.

[0181] If the second spatial filter management event is predefined, the terminal device reports the first prediction result of the spatial filter management event according to the predefinition in the protocol.

[0182] In one example, when the first prediction information indicates that event A has occurred, the terminal device does not need to report it, nor does it need to trigger subsequent spatial filter management operations.

[0183] In one example, when the first prediction information indicates that event C has occurred, the terminal reports the first prediction result of event C.

[0184] In some embodiments, the second information is transmitted via uplink control information or MAC CE.

[0185] In one example, uplink signaling carrying the second information may be reported using uplink control information (UCI) of the physical layer, where the UCI may be carried on a PUCCH of the physical layer.

[0186] In one example, the UE may use a MAC CE to carry the reporting of the second information, wherein the MAC CE may be carried on a PUSCH of the physical layer.

[0187] In some embodiments, for one of the second spatial filter management events, the second information includes one or more of the following information:

[0188] third indication information, where the third indication information is used to indicate an event type of the second spatial filter management event;

[0189] first information of the service spatial filter corresponding to the second spatial filter management event;

[0190] first information of a candidate spatial filter corresponding to the second spatial filter management event;

[0191] The second spatial filter manages a timing advance of a candidate spatial filter corresponding to the event;

[0192] The second spatial filter manages power control parameters of candidate spatial filters corresponding to the event.

[0193] It is understandable that for the second spatial filter management event, the reported content includes but is not limited to one or more of the following information:

[0194] The second spatial filter manages the type of event;

[0195] An index of a candidate spatial filter when a corresponding candidate spatial filter exists for the second spatial filter management event;

[0196] an index of a serving spatial filter when a corresponding serving spatial filter exists for the second spatial filter management event;

[0197] link quality of the candidate spatial filter when a corresponding candidate spatial filter exists in the second spatial filter management event;

[0198] a link quality of a serving spatial filter when a corresponding serving spatial filter exists in the second spatial filter management event;

[0199] A timing advance of a candidate spatial filter when a corresponding candidate spatial filter exists for a second spatial filter management event;

[0200] The second spatial filter management event includes a power control parameter of a candidate spatial filter when a corresponding candidate spatial filter exists.

[0201] In some embodiments, the terminal device receives first configuration information sent by the network device, where the first configuration information is used to configure a first uplink resource; and the first uplink resource is used to transmit the second information.

[0202] In some embodiments, the network device sends first configuration information to the terminal device, where the first configuration information is used to configure a first uplink resource; and the first uplink resource is used to transmit the second information.

[0203] The resources used for the personal information reported by the terminal device are first uplink resources, and the first uplink resources are configured by the network device based on the first configuration information.

[0204] It is understandable that the network device may actively send the first configuration information to the terminal device or may send the first configuration information to the terminal device based on a request from the terminal device.

[0205] In some embodiments, the terminal device sends a first request to the network device, where the first request is used to request the first uplink resource.

[0206] In some embodiments, the network device receives a first request sent by the terminal device, where the first request is used to request the first uplink resource.

[0207] The terminal device sends a first request to the network device to request the network device to configure the first uplink resource. The network device receives the first request sent by the terminal device and returns first configuration information to the terminal device in response to the first request.

[0208] The terminal device sends a first request to request the network device to schedule a first uplink resource for the terminal device. The first request may be a scheduling request (SR).

[0209] 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.

[0210] In some embodiments, the sending of the first request is before or after determining the second spatial filter management event.

[0211] If the first request is sent before the second spatial filter management event is determined, the terminal device will request the first uplink resource from the network device in advance without determining the second spatial filter management event, thereby requesting the first uplink resource in advance and reporting the prediction result to the network device earlier.

[0212] If the first request is sent after the second spatial filter management event is determined, the terminal device may send the first request to the network device to request the first uplink resource when the second spatial filter management event is determined.

[0213] In some embodiments, based on FIG5 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG7 , including:

[0214] S701. The terminal device receives third information sent by the network device, where the third information is used to indicate a target spatial filter, and the third information is related to the second information.

[0215] In some embodiments, based on FIG6 , an embodiment of the present application provides a wireless communication method, which is applied to a network device, as shown in FIG8 , including:

[0216] S801. The network device sends third information to the terminal device, where the third information is used to indicate a target spatial filter and is related to the second information.

[0217] After receiving the second information sent by the terminal device, the network device determines third information based on or without the second information in response to the second information, and sends the third information to the terminal device, wherein the third information is used to indicate the target spatial filter.

[0218] Optionally, the third information is a TCI state. The network device indicates one or a set of new TCI states to the terminal device through a beam indication mechanism. One TCI state corresponds to a combined (uplink and downlink) TCI state, i.e., a set of TCI states corresponds to an uplink TCI state and a downlink TCI state. The spatial filter included in the TCI state indicated by the network device is the target spatial filter.

[0219] In the embodiment of the present application, the target spatial filter indicated by the third information may belong to the first spatial filter or may not belong to the first spatial filter. It is understandable that if the target spatial filter belongs to the first spatial filter, the terminal device has measured the target spatial filter; if the target spatial filter does not belong to the first spatial filter, the terminal device has not measured the target spatial filter.

[0220] In some embodiments, if the target spatial filter does not belong to the first spatial filter, the third information is further used to indicate a first measurement resource, where the first measurement resource is used for measuring the target spatial filter and / or reporting a measurement result.

[0221] If the target spatial filter indicated by the third information is a spatial filter that the terminal device has not previously measured, the third information 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 spatial filter through the first measurement resources. The first measurement resources may include CSI-RS resources and / or SSB resources.

[0222] In one example, the terminal device can complete downlink synchronization or adjust the downlink receiving spatial filter, etc. by measuring the SSB resource in the first measurement resource.

[0223] In one example, the terminal device may track time and frequency by measuring the CSI-RS of the target spatial filter, or obtain the CSI information of the spatial filter in advance and feed it back to the network device.

[0224] Optionally, the terminal device may calculate the path loss compensation in the uplink power control by measuring the downlink reference signal as the path loss reference signal.

[0225] In an embodiment of the present application, the terminal device can determine how to receive the new beam associated with the TCI state indicated by the network device by measuring the first measurement resource, so that the terminal device can adapt to the updated service beam (previously the candidate beam), i.e., the target beam, as quickly as possible.

[0226] In some embodiments, based on FIG. 4 , FIG. 5 , or FIG. 7 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 9 , including:

[0227] S901. The terminal device receives second configuration information sent by the network device, where the second configuration information is used to configure a first set and a second set, where the first set includes one or more second measurement resources corresponding to the first spatial filters, and the second set includes one or more prediction resources corresponding to the third spatial filters, where the second spatial filter is one of the one or more third spatial filters.

[0228] In some embodiments, based on FIG. 6 or FIG. 8 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 10 , including:

[0229] S1001. The network device sends second configuration information to the terminal device, where the second configuration information is used to configure a first set and a second set, where the first set includes one or more second measurement resources corresponding to the first spatial filters, and the second set includes one or more prediction resources corresponding to the third spatial filters, where the second spatial filter is one of the one or more third spatial filters.

[0230] The first set may be labeled as measurement set Set B, where Set B includes a first number of measurement resources of the first spatial filter, ie, second measurement resources.

[0231] The second set may be labeled as prediction set Set A, where Set A includes a second number of measurement resources, ie, prediction resources, of the third spatial filter.

[0232] It can be understood that the second spatial filter corresponding to the first prediction result belongs to the second number of third spatial filters corresponding to the second set, wherein the spatial filter corresponding to the first prediction information includes part or all of the spatial filters in the second number of third spatial filters, that is, the second spatial filter corresponding to the first prediction result should be selected from the third cell corresponding to the prediction set Set A.

[0233] In some embodiments, the second measurement resources included in the first set and the predicted resources included in the second set do not have the same resource.

[0234] Here, Set B and Set A may also be different.

[0235] In one example, Set B contains SSB-based wide beams (fewer in number, such as 8 downlink transmit beams), while Set A contains CSI-RS-based narrow beams (more in number, such as 64 downlink transmit beams).

[0236] In some embodiments, the first set is a subset of the second set.

[0237] Here, Set B can be a subset of Set A.

[0238] In one example, Set A includes all beams (pairs) of a cell, and Set B includes some beams (pairs) of a cell.

[0239] In one example, for downlink transmit beams, it is assumed that Set A has downlink reference signal resources corresponding to 64 transmit beams, and Set B has downlink reference signal resources corresponding to only 8 transmit beams.

[0240] In one example, for downlink transmit / receive beam pairs, it is assumed that Set A has downlink reference signal resources corresponding to 256 transmit / receive beam pairs, and Set B has downlink reference signal resources corresponding to only 32 transmit / receive beam pairs.

[0241] In the embodiment of the present application, when the first set is a subset of the second set, the measurement overhead and delay can be reduced.

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

[0243] a third spatial filter management event, where the third spatial filter management event is a spatial filter management event for which the one or more first measurement results are used for prediction;

[0244] The first uplink resource or the second uplink resource, the first uplink resource is used to report a spatial filter management event, the second uplink resource is used to transmit a first request, and the first request is used to request the first uplink resource.

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

[0246] The first uplink resource is a resource used by the terminal device to report the second spatial filter management event. The second uplink resource is a resource used by the terminal device to request the first uplink resource.

[0247] It is understandable that if the second configuration information is configured with a first uplink resource, the terminal device reports the second spatial filter management event based on the first uplink resource configured by the second configuration information. If the second 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 second configuration information to request the network device to schedule the first uplink resource to the terminal device.

[0248] In some embodiments, based on FIG. 4 or FIG. 5 or FIG. 7 or FIG. 9 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 11 , including:

[0249] S1101. The terminal device sends fourth information to a network device, where the fourth information is used to indicate one or more of the following capabilities of the terminal device:

[0250] 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;

[0251] one or more fourth spatial filter management events, wherein the fourth spatial filter management event is a spatial filter management event predicted by the one or more first measurement results;

[0252] A first quantity, where the first quantity is the quantity of second measurement resources supported by the terminal device on one carrier, and the second measurement resource corresponds to a first spatial filter;

[0253] a second number, where the second number is the number of prediction resources supported by the terminal device on one carrier, the prediction resources corresponding to a second spatial filter;

[0254] a third quantity, where the third quantity is the quantity of second measurement resources supported by the terminal device on all carriers;

[0255] A fourth quantity, the fourth quantity being the quantity of predicted resources supported by the terminal device on all carriers.

[0256] In some embodiments, based on FIG. 6 , FIG. 8 , or FIG. 10 , an embodiment of the present application provides a wireless communication method, applied to a network device, as shown in FIG. 11 , including:

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

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

[0259] one or more fourth spatial filter management events, wherein the fourth spatial filter management event is a spatial filter management event predicted by the one or more first measurement results;

[0260] A first quantity, where the first quantity is the quantity of second measurement resources supported by the terminal device on one carrier, and the second measurement resource corresponds to a first spatial filter;

[0261] a second number, where the second number is the number of prediction resources supported by the terminal device on one carrier, the prediction resources corresponding to a second spatial filter;

[0262] a third quantity, where the third quantity is the quantity of second measurement resources supported by the terminal device on all carriers;

[0263] A fourth quantity, the fourth quantity being the quantity of predicted resources supported by the terminal device on all carriers.

[0264] In an embodiment of the present application, the terminal device reports the measurement and prediction capabilities supported by the terminal device to the network device based on the fourth information.

[0265] Here, the first spatial filter management event, the second spatial filter management event, the third spatial filter management event, and the fourth spatial filter management event are described:

[0266] The first spatial filter management event is a spatial filter management event predicted by the terminal device based on one or more first measurement results;

[0267] The second spatial filter management event is a reported spatial filter management event predicted by the terminal device based on one or more first measurement results;

[0268] The third spatial filter management event is a spatial filter management event that can be predicted by the terminal device configured by the network device based on one or more first measurement results;

[0269] The fourth spatial filter management event is a spatial filter management event that the terminal device supports prediction.

[0270] Optionally, the fourth information includes fifth indication information, and the fifth indication information is used to indicate whether the terminal device supports the measurement of the one or more first measurement results and / or whether it supports the prediction of the first prediction information based on the one or more first measurement results. If the fourth indication information indicates that the terminal device supports the measurement of the one or more first measurement results and supports the prediction of the first prediction information based on the one or more first measurement results, the fourth information is used to indicate other content, or the fourth information does not include the fourth indication information. When indicating other content, it is assumed that the terminal device supports the measurement of the one or more first measurement results and supports the prediction of the first prediction information based on the one or more first measurement results.

[0271] 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.

[0272] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG12 , including:

[0273] S1201. A terminal device sends one or more first measurement results to a network device, where the first measurement results are measurement results obtained by measuring a first spatial filter.

[0274] The one or more first measurement results are used by the network device to predict first prediction information, the first prediction information is related to the one or more first prediction results, and the first prediction result is a measurement result of the second spatial filter predicted based on the one or more first measurement results.

[0275] An embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG13 , including:

[0276] S1301. A network device receives one or more first measurement results sent by a terminal device, where the first measurement results are measurement results obtained by measuring a first spatial filter.

[0277] S1302. The network device predicts first prediction information based on the one or more first measurement results, where the first prediction information is related to the one or more first prediction results, and the first prediction result is a measurement result of a second spatial filter predicted based on the one or more first measurement results.

[0278] The terminal device measures a first number of first spatial filters to obtain a measurement result of each of the first spatial filters in the first number of first spatial filters, that is, obtains a first number of first measurement results. The first number is an integer greater than or equal to 1. It is understandable that one measurement resource corresponds to one spatial filter.

[0279] The first measurement result in the embodiment of the present application may be a measurement result obtained by performing layer 1 measurement on the first spatial filter. The first measurement result may include: one or more of: L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR.

[0280] The measurement resources of the first spatial filter may be CSI-RS resources and / or SSB resources.

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

[0282] The first quantity of first measurement results may be reported to the network device via uplink signaling. In some embodiments, the uplink signaling is reported in uplink control information (UCI) of the physical layer in the form of a spatial filter report. The UCI may be carried via a PUCCH or a physical uplink shared channel (PUSCH). The uplink signaling may also be MAC CE or RRC signaling.

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

[0284] The first prediction result is a measurement result of the second spatial filter predicted based on the first number of first measurement results. The first number of first measurement results may predict one or more first prediction results, and different first prediction results in the multiple first prediction results correspond to different second spatial filters. It is understandable that the first prediction result is the measurement result of the second spatial filter, but the first prediction result is not a measurement result obtained by measuring the second spatial filter, but rather a measurement result predicted or inferred based on the first number of first measurement results.

[0285] It can be understood that the second spatial filter belongs to the first number of first spatial filters or does not belong to the first number of first spatial filters.

[0286] In one example, a network device obtains first prediction information related to prediction results of beam 4 and beam 5 based on the measurement results of beam 1, beam 2, and beam 3, wherein the prediction results of beam 4 and beam 5 are predicted based on the measurement results of beam 1, beam 2, and beam 3.

[0287] In one example, a network device obtains first prediction information related to prediction results of beam 3 and beam 4 based on the measurement results of beam 1, beam 2, and beam 3, wherein the prediction results of beam 3 and beam 4 are predicted based on the measurement results of beam 1, beam 2, and beam 3.

[0288] It can be understood that a beam may be a service beam or a candidate beam of the terminal device, wherein the service beam is the beam of the service cell of the terminal device, and the candidate beam may be the beam of the service cell or the beam of the candidate cell.

[0289] 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 number of first measurement results into the second prediction model to obtain first prediction information output by the second prediction model.

[0290] 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.

[0291] In the wireless communication method provided in an embodiment of the present application, a terminal device measures a first number of first measurement results and reports the measurement results to a network device. The network device determines first prediction information related to the predicted measurement results of one or more second cells based on the one or more first measurement results, thereby obtaining the first prediction information without the need to measure the one or more second cells, thereby reducing the overhead of the reference signal used for spatial filter measurement.

[0292] In some embodiments, the first prediction information includes one or more of the following:

[0293] first indication information, where the first indication information is used to indicate whether one or more first spatial filter management events occur, where the first spatial filter management events are related to the first prediction result;

[0294] second indication information, where the second indication information is used to indicate an event type of the first spatial filter management event;

[0295] first information of the service spatial filter corresponding to the first spatial filter management event;

[0296] The first spatial filter manages first information of a candidate spatial filter corresponding to the event.

[0297] In an embodiment of the present application, the first indication information may be used to indicate whether one or more first spatial filter management events occur in the terminal device.

[0298] It is understandable that different values ​​of the first indication information are used to indicate that one or more first spatial filter management events have occurred, or that no first spatial filter management event has occurred.

[0299] In the embodiment of the present application, if the first prediction information includes the second indication information, the first prediction information may include the first indication information or may not include the first indication information.

[0300] In some embodiments, the one or more first spatial filter management events are preset spatial filter management events. In this case, the first indication information is used to indicate whether the preset spatial filter management event occurs.

[0301] If a first spatial filter management event occurs, the second indication information is used to indicate which first spatial filter management event occurred. It is understood that if multiple first spatial filter management events occur, the first prediction information includes multiple second indication information, with different second indication information indicating different event types of first spatial filter management events.

[0302] If the spatial filter corresponding to the first spatial filter management event includes a serving spatial filter, the first prediction information may include first information of the serving spatial filter corresponding to the first spatial filter management event.

[0303] If the spatial filter corresponding to the first spatial filter management event includes a candidate spatial filter, the first prediction information may include first information of the candidate spatial filter corresponding to the first spatial filter management event.

[0304] In some embodiments, the one or more first spatial filter management events include one or more of the following events:

[0305] Event A: the one or more second spatial filters corresponding to the one or more first spatial filter management events include a serving spatial filter, and the performance of the serving spatial filter is better than a first threshold;

[0306] Event B: the one or more second spatial filters include a serving spatial filter, and performance of the serving spatial filter is weaker than a second threshold;

[0307] Event C: the one or more second spatial filters include a candidate spatial filter and a serving spatial filter of the serving cell, and performance of the candidate spatial filter of the serving cell is better than performance of the first spatial filter, where the performance of the first spatial filter is the performance of the serving spatial filter plus a first offset;

[0308] Event D: the one or more second spatial filters include a candidate spatial filter of the candidate cell and a serving spatial filter, performance of the candidate spatial filter of the candidate cell is better than performance of the second spatial filter, and the performance of the second spatial filter is the performance of the serving spatial filter plus a second offset;

[0309] Event E: the one or more second spatial filters include a candidate spatial filter of a serving cell, and performance of the candidate spatial filter of the serving cell is better than a third threshold;

[0310] Event F: the one or more second spatial filters include a candidate spatial filter of a candidate cell, and performance of the candidate spatial filter of the candidate cell is better than a fourth threshold;

[0311] Event G: the one or more second spatial filters include a serving spatial filter and a candidate spatial filter of a serving cell, performance of the serving spatial filter is weaker than a fifth threshold, and performance of the candidate spatial filter of the serving cell is better than a sixth threshold;

[0312] Event H: the one or more second spatial filters include a serving spatial filter and a candidate spatial filter of a candidate cell, performance of the serving spatial filter is weaker than a seventh threshold, and performance of the candidate spatial filter of the candidate cell is better than an eighth threshold;

[0313] Event 1: the one or more second spatial filters include a service spatial filter, and performance fluctuation of the service spatial filter exceeds a first range;

[0314] Event J: the one or more second spatial filters include a candidate spatial filter of a serving cell, and interference of the candidate spatial filter of the serving cell is stronger than a first interference threshold;

[0315] Event K: the one or more second spatial filters include a candidate spatial filter of a candidate cell, and interference of the candidate spatial filter of the candidate cell is stronger than a second interference threshold.

[0316] For the multiple threshold values ​​involved in events A to J, the values ​​of different threshold values ​​may be the same or different.

[0317] In the embodiment of the present application, the performance of the spatial filter can be represented by one or more parameters of the spatial filter, including L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, and SNR, which represent the link quality of the cell.

[0318] It is understandable that if the second spatial filter has a first measurement result and a first prediction result, the terminal device can determine whether the first spatial filter management event occurs for the second spatial filter based on the first measurement result and / or the first prediction result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the first measurement result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the first prediction result of the second spatial filter. Optionally, the terminal device determines whether the first spatial filter management event occurs for the second spatial filter based on the result with better link performance between the first measurement result and the first prediction result of the second spatial filter.

[0319] In some embodiments, the performance fluctuations include one or more of the following:

[0320] Fluctuation parameter 1: the number of times the link quality fluctuates above the ninth threshold within the first duration;

[0321] Fluctuation parameter 2: duration during which the link quality is less than the tenth threshold within the second time period.

[0322] Fluctuation parameter 3: Ratio of the duration of link quality less than the eleventh threshold during the third duration to the total duration

[0323] For the first fluctuation parameter, the first duration is a specific duration determined by the first time window. The first waveform parameter is the number of times the link quality fluctuates above the ninth threshold within the first time window.

[0324] The number of times the link quality fluctuates on the ninth threshold may include: the number of times the link quality changes from a value greater than the ninth threshold to a value less than the ninth threshold, and / or the number of times the link quality changes from a value less than the ninth threshold to a value greater than the ninth threshold.

[0325] For the second fluctuation parameter, the second duration is a specific duration determined by the second time window. The second waveform parameter is the duration during which the link quality is lower than a specific threshold, ie, the tenth threshold, within the specific duration.

[0326] It is understandable that the duration during which the link quality is lower than the tenth threshold may be the duration of a time period during which the link quality is lower than the tenth threshold or the sum of the durations of multiple time periods.

[0327] For the third fluctuation parameter, the third duration is a specific duration determined by the third time window. The third fluctuation parameter is the ratio of the duration of the link quality being below a specific threshold, namely the eleventh threshold, to the total duration within the specific duration.

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

[0329] Cell index;

[0330] Spatial filter index;

[0331] Spatial filter link quality.

[0332] In the embodiment of the present application, when the spatial filter to which the first information belongs is the spatial filter of the serving cell, the first information may not include the cell index of the serving cell.

[0333] In an example, the first prediction information determined by the terminal device based on the one or more first measurement results includes one or more of the following:

[0334] The event type of event G;

[0335] Candidate beam index;

[0336] Link quality of candidate beams;

[0337] Serving beam index;

[0338] Link quality of the serving beam.

[0339] Among them, if the candidate beam comes from a non-serving cell, that is, a candidate, the first prediction information also includes the index of the candidate cell, such as the physical cell identifier PCI that is different from the serving cell.

[0340] In some embodiments, the transmission manner of the plurality of first measurement results includes one of the following:

[0341] The reporting is performed based on multiple reporting instances, and the multiple first measurement results are divided into the multiple reporting instances.

[0342] Here, if multiple first measurement results need to be reported, the terminal device divides the multiple first measurement results into multiple reporting instances and reports the multiple first measurement results in batches based on the multiple reporting instances. After receiving the multiple reporting instances, the network device integrates the first measurement results in the multiple reporting instances to obtain the multiple first measurement results reported by the terminal device. The number of reporting instances included in the multiple reporting instances is a third number, and the third number is less than the first number.

[0343] Optionally, the measurement resources of the first number of spatial filters are divided into multiple subsets, and in one reporting instance, only the first measurement results corresponding to the measurement resources included in one subset are reported.

[0344] In one example, the measurement resources of the first number of spatial filters are divided into four subsets, namely, Set B1, Set B2, Set B3, and Set B4. In one reporting instance, only the content of one subset is reported.

[0345] In the embodiment of the present application, the division of subsets may be configured or predefined by the network device.

[0346] In one example, the division of each subset is a network device configuration. When the UE reports different subsets, the network device can splice the reported contents of multiple subsets.

[0347] In an embodiment of the present application, dividing multiple first measurement results into multiple reporting instances can reduce the overhead of the terminal device in one measurement and reporting instance.

[0348] In some embodiments, based on FIG12 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG14 , including:

[0349] S1401. The terminal device receives fifth information sent by the network device, where the fifth information is used to indicate a target spatial filter, and the fifth information is related to the first prediction information.

[0350] In some embodiments, based on FIG13 , an embodiment of the present application provides a wireless communication method, which is applied to a terminal device, as shown in FIG15 , including:

[0351] S1501. The network device receives fifth information sent by the terminal device, where the fifth information is used to indicate a target spatial filter, and the fifth information is related to the first prediction information.

[0352] The network device determines, based on the first prediction result, that a first spatial filter management event has occurred on the terminal device, determines fifth information based on or without the occurrence of the first spatial filter management event, and sends the fifth information to the terminal device, wherein the fifth information is used to indicate a target spatial filter.

[0353] Optionally, the third information is a TCI state. The network device indicates one or a set of new TCI states to the terminal device through a beam indication mechanism. One TCI state corresponds to a combined (uplink and downlink) TCI state, i.e., a set of TCI states corresponds to an uplink TCI state and a downlink TCI state. The spatial filter included in the TCI state indicated by the network device is the target spatial filter.

[0354] In the embodiment of the present application, the target spatial filter indicated by the fifth information may belong to the first spatial filter or may not belong to the first spatial filter. It is understandable that if the target spatial filter belongs to the first spatial filter, the terminal device has measured the target spatial filter; if the target spatial filter does not belong to the first spatial filter, the terminal device has not measured the target spatial filter.

[0355] In some embodiments, if the target spatial filter does not belong to the first spatial filter, the fifth information is further used to indicate a first measurement resource, where the first measurement resource is used for measuring the target spatial filter and / or reporting a measurement result.

[0356] When the target spatial filter indicated by the fifth information is a spatial filter that the terminal device has not previously measured, the fifth information 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 spatial filter through the first measurement resources. The first measurement resources may include CSI-RS resources and / or SSB resources.

[0357] In one example, the terminal device can complete downlink synchronization or adjust the downlink receiving spatial filter, etc. by measuring the SSB resource in the first measurement resource.

[0358] In one example, the terminal device may track time and frequency by measuring the CSI-RS of the target spatial filter, or obtain the CSI information of the spatial filter in advance and feed it back to the network device.

[0359] Optionally, the terminal device may calculate the path loss compensation in the uplink power control by measuring the downlink reference signal as the path loss reference signal.

[0360] In an embodiment of the present application, the terminal device can determine how to receive the new beam associated with the TCI state indicated by the network device by measuring the first measurement resource, so that the terminal device can adapt to the updated service beam (previously the candidate beam), i.e., the target beam, as quickly as possible.

[0361] In some embodiments, based on FIG. 12 or 14 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 16 , including:

[0362] S1601. The terminal device receives third configuration information sent by the network device, where the third configuration information is used to configure a first set, where the first set includes one or more second measurement resources corresponding to the first spatial filters.

[0363] In some embodiments, based on FIG. 13 or 15 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 17 , including:

[0364] S1701. The network device sends third configuration information to the terminal device, where the third configuration information is used to configure a first set, where the first set includes one or more second measurement resources corresponding to the first spatial filters.

[0365] The first set may be labeled as measurement set Set B, where Set B includes a first number of measurement resources of the first spatial filter, ie, second measurement resources.

[0366] In some embodiments, the third configuration information is further used to configure:

[0367] A third uplink resource, where the third uplink resource is used to report the one or more first measurement results.

[0368] The third uplink resource is a resource for the terminal device to report the first measurement result. The terminal device reports the first measurement result based on the third uplink resource.

[0369] If the multiple first measurement results are divided into multiple reporting instances and reported, the third configuration information is used to configure multiple third uplink resources, where one third uplink resource corresponds to one reporting instance.

[0370] In some embodiments, based on FIG. 12 , FIG. 14 , or FIG. 16 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 18 , including:

[0371] S1801. The terminal device sends sixth information to the network device, where the sixth information is used to indicate one or more of the following capabilities of the terminal device:

[0372] whether the terminal device supports measurement of the one or more first measurement results;

[0373] A first quantity, where the first quantity is the quantity of second measurement resources supported by the terminal device on one carrier, and the second measurement resource corresponds to a first spatial filter;

[0374] A third quantity, where the third quantity is the quantity of second measurement resources supported by the terminal device on all carriers.

[0375] In some embodiments, based on FIG. 13 , FIG. 15 , or FIG. 17 , an embodiment of the present application provides a wireless communication method, as shown in FIG. 18 , including:

[0376] S1801. The network device receives sixth information sent by the terminal device, where the sixth information is used to indicate one or more of the following capabilities of the terminal device:

[0377] whether the terminal device supports measurement of the one or more first measurement results;

[0378] A first quantity, where the first quantity is the quantity of second measurement resources supported by the terminal device on one carrier, and the second measurement resource corresponds to a first spatial filter;

[0379] A third quantity, where the third quantity is the quantity of second measurement resources supported by the terminal device on all carriers.

[0380] In an embodiment of the present application, the terminal device reports the measurement capabilities supported by the terminal device to the network device based on the sixth information.

[0381] Optionally, the sixth information includes sixth indication information, and the sixth indication information is used to indicate whether the terminal device supports the measurement of the one or more first measurement results. If the sixth indication information indicates that the terminal device supports the measurement of the one or more first measurement results, 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 the measurement of the one or more first measurement results.

[0382] 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.

[0383] The following further describes the wireless communication method provided in the embodiments of the present application.

[0384] In the embodiment of the present application, the spatial filter management event, i.e., the beam management event, is defined as follows:

[0385] Event 1: The performance of the serving beam of the serving cell is better than a specific threshold;

[0386] Event 2: The performance of the serving beam of the serving cell is weaker than a specific threshold;

[0387] Event 3: The performance of the candidate beam of the serving cell is better than the current serving beam plus the offset;

[0388] Event 4: The performance of the candidate beam of the non-serving cell is better than the current serving beam plus the offset;

[0389] Event 5: The performance of the candidate beam of the serving cell is better than a specific threshold;

[0390] Event 6: The performance of the candidate beam of the non-serving cell is better than a specific threshold;

[0391] Event 7: The performance of the serving beam of the serving cell is weaker than a specific threshold, and the performance of the candidate beam of the serving cell is better than a specific threshold;

[0392] Event 8: The performance of the serving beam of the serving cell is weaker than a specific threshold, and the performance of the candidate beam of the non-serving cell is better than a specific threshold;

[0393] Event 9: The performance fluctuation of the serving beam of the serving cell exceeds a certain range;

[0394] Event 10: The interference from the candidate beam of the serving cell is stronger than a certain threshold for the UE;

[0395] Event 11: The interference of the candidate beam of the non-serving cell is stronger than a certain threshold for the UE.

[0396] Here, events 1 to 11 correspond to events A to K, respectively.

[0397] The performance of the serving beam or candidate beam can be measured using physical layer metrics such as L1-RSRP, L1-RSRQ, L1-RSSI, L1-SINR, as well as SNR and PDCCH BLER. This metric can also serve as the input and output of the model for link quality.

[0398] For beam link quality fluctuations during beam management events, as shown in Figure 19 , it is the number of times the link quality crosses a predefined threshold from top to bottom within a time period (e.g., a time window). In other embodiments, the indicator for measuring link performance fluctuations can be the duration of link quality below a specific threshold (the sum of T1 and T2) within a specific time period (e.g., a time window), as shown in Figure 20 , or the ratio of the duration of link quality below a specific threshold to the total duration.

[0399] For the PDCCH block error rate (BLER), the UE can convert the measured L1-SINR into the control channel BLER according to the conditions defined in the standard. Generally, when the PDCCH BLER is higher than 1%, the link quality is considered poor and needs to be adjusted.

[0400] Figure 21 shows serving beam 2101 and candidate beam 2102 in a serving cell, as well as candidate beam 2103 in a non-serving cell. It should be noted that NR supports inter-cell beam management, meaning that beams in non-serving cells can also be converted into serving beams.

[0401] The wireless communication methods provided in the embodiments of the present application include but are not limited to the following embodiments:

[0402] Example 1: Beam event prediction with model deployed on the UE side

[0403] The wireless communication method provided in the embodiment of the present application, as shown in FIG22 , includes:

[0404] S2201. UE reports its capabilities.

[0405] The UE reports its supported beam management event measurement and prediction capabilities. Specifically, the UE first informs the NW whether it supports beam event-related measurement and / or prediction.

[0406] If the UE capability supports it, the UE needs to report other capability details related to measurement and / or prediction. The purpose of this capability reporting is to facilitate subsequent configuration by the NW.

[0407] Such measurement and prediction capabilities include but are not limited to:

[0408] Capability 1: Which beam management events does the UE-side model support prediction of?

[0409] Capability 2: On one component carrier (CC), the UE supports a maximum number of measurement resources for measurement, ie, a first quantity.

[0410] ○ In some embodiments, the downlink measurement resource is a downlink reference signal resource, ie, a CSI-RS resource and / or an SSB resource.

[0411] Capability 3: On one carrier, the UE supports a maximum number of prediction resources, that is, a second number.

[0412] In some embodiments, the prediction resource is also a downlink reference signal resource, such as a CSI-RS resource and / or an SSB resource. Generally, one downlink reference signal resource corresponds to one candidate beam.

[0413] Considering the measurement overhead of the UE, the UE capability should not only be considered on one carrier, but also on all configured and / or activated carriers.

[0414] Capability 4: On all carriers, the UE supports measurement of a maximum number of measurement resources, i.e., the third quantity.

[0415] Capability 5: On all carriers, the UE supports a maximum number of prediction resources, that is, the fourth quantity.

[0416] S2202: The NW configures measurement resources and prediction resources.

[0417] The configuration signaling used by the NW is generally RRC signaling. In some other embodiments, it can be high-layer signaling from the core network.

[0418] Based on the UE's capability report, the NW predicts resources related to beam management events for the UE. This configuration includes but is not limited to:

[0419] Configuration 1: The beam management event type that the UE can predict is the fourth beam management event. For example, the UE can predict event 1, event 3, and event 5. The beam management that cannot be predicted is event 2 and event 4.

[0420] Configuration 2: UE-measured beam management event measurement set Set B. This set contains one or more downlink reference signal resources. In some embodiments, the resources are CSI-RS resources and / or SSB resources.

[0421] Configuration 3: UE-predicted beam management event prediction set Set A. This set contains the reference signal resources corresponding to the candidate beams.

[0422] In addition, the NW may optionally configure some configuration information 4 for the UE: uplink resources (i.e., PUSCH or PUCCH). When there is a beam management event that needs to be reported, the uplink resource is used to carry the report of the model prediction event. Here, PUCCH is used to directly carry the report of the beam management event.

[0423] In some embodiments, the NW configures a PUCCH resource for the UE to request uplink resources. The PUCCH resource is used to carry an uplink resource scheduling request (SR), and the PUSCH is used to carry the reporting of beam management events.

[0424] S2203. The UE infers beam management events through the model.

[0425] In an embodiment of the present application, the prediction of beam management events in the spatial domain is considered. In some embodiments, Set B may be a subset of Set A. For example, Set A contains all beams (pairs) of the cell. In some embodiments, for downlink transmit beams, it is assumed that Set A has downlink reference signal resources corresponding to 64 transmit beams, but in order to reduce the measurement overhead and delay, Set B only has downlink reference signal resources corresponding to 8 transmit beams. In other embodiments, for downlink transmit-receive beam pairs, it is assumed that Set A has downlink reference signal resources corresponding to 256 transmit-receive beam pairs, but in order to reduce the measurement overhead and delay, Set B only has downlink reference signal resources corresponding to 32 transmit-receive beam pairs.

[0426] In some other embodiments, Set B may be different from Set A. For example, Set B may include SSB-based wide beams (a smaller number, such as 8 downlink transmit beams), while Set A may include CSI-RS-based narrow beams (a larger number, such as 64 downlink transmit beams).

[0427] After the UE completes the measurement, the measurement results of Set B can be used as input to the model. The model uses this to make inferences or predictions. The reference signal resources corresponding to the beams of the inference results should be selected from the prediction set A.

[0428] The prediction result, i.e., the first prediction information, includes one or more of the following:

[0429] ●Whether a beam management event defined in the embodiments of this application and configured by the NW occurs;

[0430] If a beam management event occurs, which beam management event occurred (i.e., event type) and related information about the beam management event; the beam management event information includes one or more of the following:

[0431] ○Service beam information corresponding to the beam management event (if any)

[0432] ■Service beam link quality

[0433] ○Candidate beam information corresponding to the beam management event (if any)

[0434] ■Candidate beam link quality;

[0435] ■Timing Advance (TA) corresponding to the candidate beam; Note: Applicable only to uplink channel and signal transmission

[0436] ■One or more of the following power control parameters corresponding to the candidate beam:

[0437] Path Loss Reference Signal (PL RS);

[0438] P0, the target received power per PRB;

[0439] Alpha, the compensation factor for path loss;

[0440] ●CLI, or closed-loop power control indication;

[0441] Note: Only applicable to uplink channel and signal transmission

[0442] The model's input and output relationship is shown in Figure 23. Set B serves as the model's input. The candidate beams (pairs) output by the model are selected from Set A. In some embodiments, the model may also output predicted link quality. In other embodiments, the model may also output the timing advance corresponding to the candidate beams (applicable only to uplink transmission) and parameters related to uplink power control.

[0443] In one example, for beam management event prediction, the model outputs one or more of the following information:

[0444] Event Type 7

[0445] Candidate beam index (expressed as downlink reference signal resource index)

[0446] If the candidate beam comes from a non-serving cell, the cell's corresponding index should also be reported, such as the physical cell identifier (PCI) that is different from the serving cell.

[0447] ●Link quality of candidate beams

[0448] Serving beam index (indicated by the resource index of the downlink reference signal)

[0449] Link quality under the serving beam

[0450] S2204. The UE reports a beam management event.

[0451] In some embodiments, the UE can independently decide whether to report the model's prediction results for beam management events. For example, if the model predicts that the current serving beam is better than a specific threshold (Event 1) and maintains an appropriate serving beam link state, the UE does not need to report the prediction results and does not need to trigger subsequent beam management operations.

[0452] In other embodiments, the UE reports based on the prediction results of the NW's configured beam management event. For example, if the model outputs the optimal candidate beam (different from the current serving beam) and its performance is better than the current serving beam plus an offset (e.g., 6dB), the UE can determine that beam management event 3 has occurred and report it. This offset is generally configured in advance by the NW or predefined in the protocol.

[0453] Regarding the signaling process for reporting beam management events, in some embodiments, the UE sends a Scheduling Request (SI) to request uplink resources. Upon receiving the SI, if the network network agrees with the UE's scheduling request, it sends an uplink scheduling Directed Response Information (DCI) to the UE. The UE transmits a PUSCH based on the uplink resources indicated by the DCI. This PUSCH carries the reporting information for the beam management event.

[0454] Because the model's predictions of beam management events are inherently forward-looking, when deployed on the UE side, the UE can send scheduling requests to the NW in advance. Before an event occurs, it can request uplink resources to carry the predicted beam management event report. This technical advantage lies in the fact that requesting reporting resources in advance allows the prediction results to be reported to the NW earlier, allowing the NW to take proactive action, largely avoiding beam failures.

[0455] The reported content of beam management events includes but is not limited to the following information:

[0456] The type of the beam management event, where the beam management event type index is used to indicate the type of the beam management event;

[0457] ●Candidate beam index corresponding to the beam management event (if any), where the candidate CSI-RI resource indication (CRI) or SSB resource indication (SSBRI) (Candidate CRI or SSBRI) is used to indicate the resource index of the CSI-RI or the resource index of the SSB corresponding to the candidate beam to be reported.

[0458] The serving beam index (if any) corresponding to the beam management event, i.e., the Candidate CRI or SSBRI, is used to indicate the resource index of the CSI-RI or SSB corresponding to the serving beam to be reported.

[0459] The link quality of the candidate beam corresponding to the beam management event (if any);

[0460] The link quality of the serving beam corresponding to the beam management event (if any);

[0461] The timing advance of the candidate beam corresponding to the beam management event (if any, applicable only to uplink transmission);

[0462] The power control parameters of the candidate beam corresponding to the beam management event (if any, applicable only to uplink transmission);

[0463] For uplink signaling carrying beam management events, the physical layer uplink control information (UCI) can be used for reporting. The UE can also use MAC CE to carry the reporting of beam management events.

[0464] As shown in Table 1, the UE reports information such as the type of beam management event, including the indexes and link qualities of K (K>=1) subsequent beams, and the indexes and link qualities of N (N>=1) serving beams. In some embodiments, UCI can be carried on the PUCCH of the physical layer, similar to the beam reporting mechanism in the prior art. MAC CE can be carried on the PUSCH of the physical layer, similar to the TRP-specific beam failure recovery (BFR) in the prior art.

[0465] Table 1. Reporting of beam management events

[0466] In other embodiments, assuming the same or similar beam management prediction model is deployed on the NW side, and the model's function is to at least predict in advance whether a beam management event will occur, the NW can preemptively allocate uplink resources to the UE before the UE requests uplink resources. For example, the NW can send an uplink grant (UL grant) DCI to the UE. This technical advantage is that it avoids the UE's need to send an uplink resource request, thereby shortening the beam change time.

[0467] S2205. NW indicates the new beam to the UE.

[0468] From the candidate beams reported by the UE, the NW indicates one or a group of new TCI states to the UE through the beam indication mechanism. It should be noted that one TCI state corresponds to one combined (uplink and downlink) TCI state. A group of TCI states corresponds to one uplink TCI state and one downlink TCI state.

[0469] When the TCI state indicated by the NW (based on the candidate beams predicted by the model) includes a downlink reference signal that the UE has not previously measured, the NW should also indicate a set of downlink reference signal measurement resources. The downlink reference signal resources are a set of CSI-RS resources and / or SSB resources. This indication information can be carried in DCI or MAC CE signaling.

[0470] For example, the UE can complete downlink synchronization by measuring SSB resources, or perform receive beam scanning to adjust the downlink receive spatial filter (beam); the UE can track time and frequency by measuring the CSI-RS (Tracking RS) of the candidate beam; the UE can obtain the CSI information of the cell by measuring the CSI-RS of multiple ports and feed it back to the NW; the UE can calculate the path loss compensation in the uplink power control by measuring the downlink reference signal as the path loss reference signal.

[0471] The UE can determine how to receive the new beam associated with the TCI state by measuring the resource. The technical advantage is that the UE adapts to the updated serving beam (previously the candidate beam) at the fastest speed.

[0472] Example 2: Beam event prediction with the model deployed on the NW side

[0473] If the model is deployed on the NW side, the wireless communication method provided in the embodiment of the present application, as shown in FIG24 , includes:

[0474] S2401. UE reports its capabilities.

[0475] The UE reports its supported beam management event measurement capabilities. Specifically, the UE first informs the NW whether it supports beam event-related measurement and / or reporting.

[0476] If the UE capability supports it, the UE needs to report other capability details related to the measurement. The purpose of this capability reporting is to facilitate subsequent configuration by the NW.

[0477] This measurement capability includes but is not limited to:

[0478] Capability 2: On one carrier, the UE supports a maximum number of measurement resources.

[0479] In some embodiments, the downlink measurement resource is a downlink reference signal resource, i.e., a CSI-RS resource and / or an SSB resource.

[0480] Considering the measurement overhead of the UE, the UE capability should not only be considered on one carrier, but also on all configured and / or activated carriers.

[0481] Capability 4: On all carriers, the UE supports the measurement of a maximum number of measurement resources.

[0482] S2402: The NW configures measurement resources.

[0483] Based on the UE's capability report, the NW configures resources related to beam management event measurement for the UE. It should be noted that because the model is deployed on the NW side, there is no need to configure beam management event information to the UE.

[0484] The configuration includes but is not limited to:

[0485] Configuration information 2: UE-measured beam management event measurement set Set B. This set contains one or more downlink reference signal resources. In some embodiments, the resources are CSI-RS resources and / or SSB resources.

[0486] The NW configures some configuration information 4 for the UE: uplink resources for carrying measurement reports. For example:

[0487] For periodic measurements, the NW can configure associated PUCCH resources for periodic reporting; can also configure and activate semi-persistent PUCCH or PUSCH for semi-persistent reporting; can also trigger aperiodic PUSCH reporting.

[0488] For semi-persistent measurement, the NW can configure and activate semi-persistent PUCCH or PUSCH for semi-persistent reporting; it can also trigger aperiodic PUSCH reporting.

[0489] For non-periodic measurement, the NW may trigger non-periodic PUSCH reporting.

[0490] S2403: The UE measures and reports the measurement result.

[0491] When the model is deployed on the NW side, the UE only needs to measure Set B and report the measurement results to the NW.

[0492] The content reported by the UE includes one or more of the following:

[0493] Index of reference signal resources in Content A and Set B

[0494] Link performance of reference signal resources in Content B and Set B, such as L1-RSRP.

[0495] When Set B contains too many resources, the UE can perform measurements and reports in batches. For example, assuming Set B contains four subsets: Set B1, Set B2, Set B3, and Set B4, the UE only reports the contents of one subset in a single reporting instance. Because the division of each subset in Set B is configured by the network workstation (NW), after the UE reports different subsets, the NW can concatenate the reports from multiple subsets into a complete Set B. This technical advantage is that it reduces the UE's overhead in a single measurement and reporting instance. After the UE measures and reports on multiple Set B subsets, the NW can piece together a complete Set B.

[0496] S2404. NW infers beam management events through the model.

[0497] For the relationship between the model's input and output, see Figure 12. When the NW receives the complete Set B, it uses it as the model's input to predict or infer beam management events. The model's output content can be found in S1103.

[0498] For example, for beam management event prediction, the model outputs one or more of the following information:

[0499] Event Type 3

[0500] Candidate beam index #1 (indicated by the downlink reference signal resource index)

[0501] ●Link quality of candidate beam #1

[0502] Candidate beam index #2 (indicated by the downlink reference signal resource index)

[0503] ●Link quality of candidate beam #2

[0504] S2405. NW indicates the new beam to the UE.

[0505] Based on the inference results of the model, if a beam management event is predicted to occur, the NW can indicate one or a group of new TCI states to the UE through the existing beam indication mechanism.

[0506] When the TCI status indicated by the NW includes downlink reference signals that the UE has not previously measured, the NW should also indicate a set of measurement resources. The downlink reference signal resources are a set of CSI-RS resources and / or SSB resources. This indication information can be carried in DCI or MAC CE signaling.

[0507] For example, the UE can achieve downlink synchronization by measuring the SSB resources of the candidate beams and adjust the downlink receive spatial filter (beam). The UE can also track time and frequency by measuring the CSI-RS (Tracking RS) of the candidate beams, or obtain the CSI information of the cell in advance and feed it back to the NW.

[0508] The UE can determine how to receive the new beam associated with the TCI state by measuring the resource. The technical advantage is that the UE adapts to the updated serving beam (previously the candidate beam) at the fastest speed.
