"At least one of the following" or the like means any combination of these items, including any combination of single item or multiple items. For example, at least one of a, b, or c can represent a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c can be single or multiple.

The technical solutions provided in the present application can also be applied to device to device (D2D) communication, vehicle-to-everything (V2X) communication, machine to machine (M2M) communication, machine type communication (MTC), and an internet of things (IoT) communication system or other communication systems.

[0086] A network element in the communication system in the embodiments of the present application can send a signal to another network element or receive a signal from another network element. The signal can include information, signaling, data, and the like. The network element can also be replaced by an entity, a network entity, a device, a communication device, a communication module, a node, a communication node, and the like. The network element is taken as an example for description in the embodiments of the present application. For example, the communication system can include at least one terminal device and at least one network device. The network device can send a downlink signal to the terminal device, and / or the terminal device can send an uplink signal to the network device. It can be understood that the terminal device in the embodiments of the present application can be replaced by a first network element, and the network device can be replaced by a second network element. Both of them perform the corresponding communication method in the present disclosure.

[0087] In a wireless communication network, e.g., in a mobile communication network, the services supported by the network are increasingly diverse, and thus the requirements to be met are increasingly diverse. For example, the network needs to be able to support ultra-high rates, ultra-low latency, and / or ultra-large connectivity. This feature makes network planning, network configuration, and / or resource scheduling increasingly complex. In addition, as the functions of the network become increasingly powerful, e.g., support for increasingly high frequency spectrum, support for high-order multiple input multiple output (MIMO) technology, support for beamforming, and / or support for new technologies such as beam management, network energy saving has become a hot research topic. These new requirements, new scenarios, and new features have brought unprecedented challenges to network planning, operation and maintenance, and efficient operation. In order to meet this challenge, artificial intelligence technology can be introduced into the wireless communication network, thereby realizing network intelligence. In order to support AI technology in the wireless network, an AI node can also be introduced into the network.

The wearable device can also be referred to as a wearable smart device, which is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. The wearable device is a portable device that is directly worn on the body or integrated into the user's clothes or accessories.

In the embodiments of the present application, the chip system can be composed of a chip, or can include the chip and other discrete devices. In the embodiments of the present application, only the apparatus for implementing the function of the terminal device is taken as an example for description, and the scheme of the embodiments of the present application is not limited in this way.

[0098] The network device in the embodiments of the present application can be a device for communicating with a terminal device, and the network device can also be referred to as an access network device or a radio access network device, for example, the network device can be a base station. The network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) for accessing a terminal device to a wireless network. The base station can broadly cover various names in the following or be replaced by the following names, such as: Node B (NodeB), evolved Node B (eNB), next generation Node B (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), primary station, secondary station, motor slide retainer (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), radio unit (RU), positioning node, etc. The base station can be a macro base station, a micro base station, a relay node, a donor node or the like, or a combination thereof. The base station can also refer to a communication module, modem or chip used in the aforementioned device or apparatus. The base station can also be a mobile switching center and a device assuming a base station function in D2D, V2X, M2M communication, a network side device in future communication network, a device assuming a base station function in future communication network, etc. The base station can support networks of the same or different access technologies. Optionally, the RAN node can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU). The embodiments of the present application do not limit the specific technology and specific device form of the network device.

[0099] The base station can be fixed or mobile. For example, a helicopter or a drone can be configured to act as a mobile base station, and one or more cells can move according to the location of the mobile base station. In other examples, the helicopter or the drone can be configured to serve as a device communicating with another base station.

[0100] In some deployments, the network device mentioned by embodiments of the present application can be a device including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit-control plane (CU-CP)) and a user plane CU node (central unit-user plane (CU-UP)), and a DU node. For example, the network device can include a gNB-CU-CP, a gNB-CU-UP, and a gNB-DU.

[0101] In some deployments, wireless access is assisted by multiple RAN nodes cooperating to assist a terminal, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or an RU, etc. The CU and the DU can be separately arranged, or can also be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit, such as an RRU, an AAU, or an RRH.

[0102] The RAN node can support one or more types of fronthaul interfaces, respectively corresponding to DUs and RUs with different functionalities. If the fronthaul interface between the DU and the RU is common public radio interface (CPRI), the DU is configured to implement one or more of baseband functions, and the RU is configured to implement one or more of radio frequency functions. If the fronthaul interface between the DU and the RU is another interface, which, compared with CPRI, moves one or more of partial baseband functions of downlink and / or uplink, such as, for downlink, one or more of precoding, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / add cyclic prefix (CP), from the DU to the RU for implementation, and for uplink, one or more of digital beamforming (BF), or fast Fourier transform (FFT) / remove cyclic prefix (CP), from the DU to the RU for implementation. In a possible implementation, the interface can be enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the split between the DU and the RU is different, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0103] Taking eCPRI Cat A as an example, for downlink transmission, with layer mapping as the cut, the DU is configured to implement layer mapping and one or more functions (i.e., one or more of encoding, rate matching, scrambling, modulation, layer mapping) before layer mapping, while other functions (e.g., one or more of resource element (RE) mapping, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / adding cyclic prefix (CP)) after layer mapping are implemented in the RU. For uplink transmission, with de-RE mapping as the cut, the DU is configured to implement de-mapping and one or more functions (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, de-RE mapping) before de-mapping, while other functions (e.g., one or more of digital BF or fast Fourier transform (FFT) / CP removal) after de-mapping are implemented in the RU. It can be understood that the function description of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, which is not described here.

[0104] In a possible design, the processing unit in the BBU for implementing baseband functions is referred to as a base band high (BBH) unit, and the processing unit in the RRU / AAU / RRH for implementing baseband functions is referred to as a base band low (BBL) unit.

[0105] In different systems, the CU (or CU-CP and CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as an O-CU (open CU), the DU can also be referred to as an O-DU, the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU. Any of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0106] In the embodiments of the present application, the apparatus for implementing the function of the network device can be a network device, or can be an apparatus capable of supporting the network device to implement the function, such as a chip system, a hardware circuit, a software module, or a hardware circuit plus a software module. The apparatus can be installed in the network device or used in matching with the network device. In the embodiments of the present application, only the apparatus for implementing the function of the network device is taken as an example for description, and the scheme of the embodiments of the present application is not limited.

[0107] The network device and / or the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water surface; and can also be deployed on airplanes, balloons and satellites in the air. The scenario where the network device and the terminal device are located is not limited in the embodiments of the present application. In addition, the terminal device and the network device can be hardware devices, or can be software functions running on special hardware, software functions running on general hardware, such as virtualized functions instantiated on a platform (for example, a cloud platform), or entities including special or general hardware devices and software functions. The specific form of the terminal device and the network device is not limited in the present application.

[0108] Optionally, the AI node can be deployed in one or more of the following positions in the communication system: an access network device, a terminal device, or a core network device, and the like, or the AI node can also be deployed separately, for example, deployed in a position other than the above-mentioned any device, such as a host or a cloud server of an over the top (OTT) system. The AI node can communicate with other devices in the communication system, which can be one or more of the following: a network device, a terminal device, or a network element of a core network, and the like.

[0109] It can be understood that the number of AI nodes is not limited in the present application. For example, when there are multiple AI nodes, the multiple AI nodes can be divided based on functions, such as different AI nodes being responsible for different functions.

[0110] It can also be understood that the AI node can be an AI network element or an AI module. The AI node can be a device independent of each other, or can be integrated in the same device to implement different functions, or can be a network element in a hardware device, or can be a software function running on special hardware, or can be a virtualized function instantiated on a platform (for example, a cloud platform), and the specific form of the AI node is not limited in the present application.

[0111] FIG. 2 is a schematic diagram of a possible application framework in a communication system. As shown in FIG. 2, network elements in the communication system are connected through interfaces (e.g., NG, Xn) or air interfaces. One or more AI modules (only one is shown in FIG. 2 for clarity) are deployed in one or more of the network element nodes, such as a core network device, an access network node (RAN node), a terminal device, or one or more devices in operation administration and maintenance (OAM). The access network node can be a single RAN node or can include multiple RAN nodes, e.g., including a CU and a DU. The CU and / or the DU can also be provided with one or more AI modules. Optionally, the CU can be further split into a CU-CP and a CU-UP. One or more AI models are deployed in the CU-CP and / or the CU-UP. Exemplarily, the CU and the DU are connected through an Fl interface. The CUs are connected through an Xn interface.

[0112] The AI module is used to implement a corresponding AI function. The AI modules deployed in different network elements can be the same or different. The AI module can implement different functions according to different parameter configurations of the model of the AI module. The model of the AI module can be configured based on one or more of the following parameters: a structural parameter (e.g., at least one of a number of neural network layers, a width of a neural network, a connection relationship between layers, a weight of a neuron, an activation function of a neuron, or a bias in the activation function), an input parameter (e.g., a type of the input parameter and / or a dimension of the input parameter), or an output parameter (e.g., a type of the output parameter and / or a dimension of the output parameter). The bias in the activation function can also be referred to as a bias of the neural network.

[0113] One AI module can have one or more models. One model can infer an output including one parameter or multiple parameters. The learning process, the training process, or the inference process of different models can be deployed in different nodes or devices, or can be deployed in the same node or device.

[0114] The network device can be a network device provided with one or more AI modules. The network device can be one or more of the core network device, the access network node (RAN node), or the OAM shown in FIG. 2. For example, the AI module can be the RIC shown in FIG. 3, such as a near-real-time RIC or a non-real-time RIC. For example, the near-real-time RIC is provided in the RAN node (for example, in the CU, the DU), and the non-real-time RIC is provided in the OAM, the cloud server, the core network device, or other network devices. The RIC can obtain a subset of data from multiple terminal devices from the RAN node (for example, the CU, the CU-CP, the CU-UP, the DU, and / or the RU), reorganize it into a training data set #2, and train based on the training data set #2. For example, the near-real-time RIC and the non-real-time RIC can be provided as a network element, respectively. The network device can be the near-real-time RIC or the non-real-time RIC.

[0115] FIG. 3 is a schematic diagram of a possible application framework in a communication system. As shown in FIG. 3, the communication system includes a RAN intelligent controller (RIC). For example, the RIC can be the AI module shown in FIG. 2, which is used to implement AI-related functions. The RIC includes a near-real-time RIC (near-RT RIC) and a non-real-time RIC (Non-RT RIC). The non-real-time RIC mainly processes non-real-time information, such as data that is not sensitive to latency, which can be on the order of seconds. The near-RT RIC mainly processes near-real-time information, such as data that is relatively sensitive to latency, which can be on the order of tens of milliseconds.

[0116] The near-RT RIC is used for model training and inference. For example, it is used to train an AI model and perform inference using the AI model. The near-RT RIC can obtain network-side and / or terminal-side information from the RAN node (for example, the CU, the CU-CP, the CU-UP, the DU, and / or the RU) and / or the terminal. This information can be used as training data or inference data. Optionally, the near-RT RIC can deliver the inference result to the RAN node and / or the terminal. Optionally, the CU and the DU, and / or the DU and the RU can exchange inference results. For example, the near-RT RIC delivers the inference result to the DU, and the DU sends it to the RU.

[0117] The non-real-time RIC is also used for model training and inference. For example, for training an AI model, inference is performed using the model. The non-real-time RIC can obtain network-side and / or terminal-side information from the RAN node (e.g., CU, CU-CP, CU-UP, DU, and / or RU) and / or the terminal. The information can be used as training data or inference data, and the inference result can be delivered to the RAN node and / or the terminal. Alternatively, the inference result can be exchanged between the CU and the DU, and / or between the DU and the RU, for example, the non-real-time RIC delivers the inference result to the DU, which then sends it to the RU.

[0118] The near-real-time RIC and the non-real-time RIC can also be separately set as a network element, respectively. Alternatively, the near-real-time RIC and the non-real-time RIC can also be part of other devices, for example, the near-real-time RIC is set in the RAN node (e.g., CU, DU), while the non-real-time RIC is set in the OAM, the cloud server, the core network device, or other network devices.

[0119] Currently, AI is introduced into wireless communication networks and has been widely applied to many application scenarios of air interface technology, such as: channel state information (CSI) feedback scenarios, CSI prediction scenarios, beam management scenarios, positioning scenarios, and the like. Exemplarily, when AI is applied in a downlink beam management scenario, a terminal device or a network device can efficiently and accurately identify the best downlink beam by using an AI model. The AI model can be located only in the terminal device or only in the network device. Specifically, AI-based beam management includes two typical use cases: spatial domain downlink beam prediction and time domain downlink beam prediction. The terminal device performs measurement according to reference signal resources, and reports an index and / or channel state information of the reference signal resources to achieve the purpose of beam management. Each reference signal resource is used to carry a reference signal, including SSB, CSI-RS, and the like, and the reference signal resource is, for example, a beam. Traditional downlink beam measurement needs to scan all reference signal resources in a reference signal resource set to obtain the optimal reference signal resource (for example, the reference signal resource with the maximum measurement value of channel state information). For a system using a large-scale antenna, the reference signal resource set can be very large (for example: 1024), and the traditional scanning process requires a large measurement overhead. After introducing AI, only part of the reference signal resources (for example, a reference signal resource set set B) in the reference signal resource set (for example, a reference signal resource set set A) can be measured, and the top-k optimal reference signal resources in the reference signal resource set set A can be predicted according to the measurement values of the channel state information corresponding to the part of the reference signal resources set B, so that the measurement overhead can be greatly reduced. Wherein, k is a positive integer. In time domain beam prediction, the AI beam prediction model can use the measurement values of the channel state information corresponding to the reference signal resources at the historical time to predict the predicted values of the channel state information at the future time, thereby improving the robustness of beam management in a scenario with fast channel changes and avoiding frequent signal measurement and switching. The beam prediction model can be located in the terminal device or the network device.

[0120] In the AI-based beam management scenario, the terminal device needs to predict the predicted values of the channel state information corresponding to each reference signal resource in the reference signal resource set according to the measurement values of the channel state information corresponding to part of the reference signal resources in the reference signal resource set, and then report one or more reference signal resources with higher predicted values of the corresponding channel state information to the network device. Therefore, improving the accuracy of predicting the channel state information corresponding to the reference signal resources is very important in the beam management scenario.

[0121] FIG. 4 is a schematic flowchart of a communication method according to an embodiment of the present application. The method in FIG. 4 is applied to a communication system, for example, the communication system in FIG. 1, FIG. 2 or FIG. 3. The network device in FIG. 4 is, for example, the network device 110 in FIG. 1, the core network device in FIG. 2, the access network node in FIG. 3. The terminal device in FIG. 4 is, for example, the terminal device in FIG. 1, FIG. 2 or FIG. 3. The method in FIG. 4 includes the following steps.

[0122] S410, obtaining a measurement value of channel state information corresponding to each reference signal resource in the first reference signal resource set.

[0123] The terminal device performs measurement according to each reference signal resource in the first reference signal resource set, and obtains a measurement value of channel state information corresponding to each reference signal resource in the first reference signal resource set. The first reference signal resource set includes at least one reference signal resource.

[0124] In some embodiments, the channel state information includes RSRP or SINR, etc.

[0125] Optionally, before step S410, the network device performs step S401.

[0126] S401, configuring a first reference signal resource set for the terminal device. Correspondingly, the terminal device determines the first reference signal resource set.

[0127] In some embodiments, each reference signal resource in the first reference signal resource set corresponds to a reference signal. The reference signal includes SSB and / or CSI-RS. The reference signal resource is, for example, a beam. In other words, the reference signal resource in the embodiments of the present application can be replaced by a beam.

[0128] In some embodiments, the network device sends fourth indication information to the terminal device. Correspondingly, the terminal device receives the fourth indication information. The fourth indication information includes the at least one reference signal. Alternatively, the fourth indication information includes an index of the at least one reference signal in the first reference signal set. The first reference signal set includes at least one reference signal.

[0129] S420, determining a predicted value of channel state information corresponding to each reference signal resource in the second reference signal resource set according to the measurement value of channel state information corresponding to each reference signal resource in the first reference signal resource set.

[0130] The terminal device predicts a prediction value of the channel state information corresponding to each reference signal resource in the second reference signal resource set according to a measurement value of the channel state information corresponding to each reference signal resource in the first reference signal resource set. The second reference signal resource set includes multiple reference signal resources, and the first reference signal resource set is a subset of the second reference signal resource set.

[0131] It should be understood that the second reference signal resource set can be a virtual set. In other words, the network device can not configure the terminal device with the second reference signal resource set.

[0132] Optionally, the terminal device takes the measurement value of the channel state information corresponding to each reference signal resource in the first reference signal resource set as an input of the first model, thereby obtaining an output of the first model, i.e., a prediction value of the channel state information corresponding to each reference signal resource in the second reference signal resource set. In other words, the terminal device determines the prediction value of the channel state information corresponding to each reference signal resource in the second reference signal resource set according to the first model and the measurement value of the channel state information corresponding to each reference signal resource in the first reference signal resource set. The first model is used to determine the prediction value of the channel state information corresponding to the reference signal resource. The first model is an AI model.

[0133] In some embodiments, the first model is a regression model.

[0134] In some embodiments, before step S410, the terminal device sends third indication information to the network device, the third indication information being used to indicate that the first model is a regression model.

[0135] S430, determining the first confidence according to the measurement value and the prediction value of the channel state information corresponding to each reference signal resource in the first reference signal resource set.

[0136] The terminal device determines the first confidence according to the measurement value of the channel state information corresponding to each reference signal resource in the first reference signal resource set obtained by measurement in S410 and the prediction value of the channel state information corresponding to each reference signal resource in the first reference signal resource set obtained by prediction in S420. The first confidence is used to determine whether the prediction value corresponding to the second reference signal resource set is reliable.

[0137] Optionally, the first confidence indication indicates at least one of: a difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources; or a distribution of the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources, the distribution of the difference including at least one of: a mean of the difference, a variance of the difference, or a standard deviation of the difference; or a difference between a mean of the measured value and a mean of the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources; or a difference between a variance of the measured value and a variance of the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources; or a difference between a standard deviation of the measured value and a standard deviation of the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources; or a maximum value x and a minimum value y in the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources.

[0138] In some embodiments, “comprising” is one of the implementations of “indicating”. For example, one possible implementation of “A indicates B” is that A includes B.

[0139] Optionally, the terminal device determines the first confidence according to the first confidence determination manner and the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources. The first confidence determination manner is used to determine the confidence of the predicted value of the channel state information corresponding to the reference signal resource.

[0140] For example, when the first confidence determination manner is used to indicate that the first confidence includes the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources, the terminal device determines the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources, i.e. the first confidence, according to the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first set of reference signal resources.

[0141] In some embodiments, the first confidence determination manner is preconfigured. Alternatively, the first confidence determination manner is indicated by the network device.

[0142] In some embodiments, before step S430, the network device sends second indication information to the terminal device. Correspondingly, the terminal device receives the second indication information from the network device. The second indication information is used to indicate the first confidence determination manner.

[0143] Exemplarily, the second indication information comprises the first confidence determination manner. Alternatively, the second indication information comprises an index of the first confidence determination manner in at least one candidate confidence determination manner. Each candidate confidence determination manner in the at least one candidate confidence determination manner is used to determine the confidence of the predicted value of the channel state information corresponding to the reference signal resource.

[0144] Exemplarily, the at least one candidate confidence determination manner is preconfigured. Alternatively, the at least one candidate confidence determination manner is indicated by the network device.

[0145] Exemplarily, before step S430, the network device sends fifth indication information to the terminal device. Correspondingly, the terminal device receives the fifth indication information from the network device. The fifth indication information is used to indicate the at least one candidate confidence determination manner.

Exemplarily, the first report is used to indicate the first confidence. Alternatively, the first report is determined according to the first confidence.

[0148] In some embodiments, after the terminal device determines the first confidence, the terminal device determines a first report according to the first confidence, and sends the first report to the network device, as shown in the method in FIG. 5.

[0149] In some embodiments, after the terminal device determines the first confidence, the terminal device directly sends a first report to the network device, as shown in the method in FIG. 6.

[0150] In the embodiments of the present application, the terminal device determines the first confidence by the measured value and the predicted value of the channel state information corresponding to the first reference signal resource set, so that the network device and / or the terminal device can determine whether the predicted value of the channel state information corresponding to the reference signal resource is credible according to the first confidence, thereby facilitating to improve the accuracy of predicting the channel state information corresponding to the reference signal resource.

[0151] FIG. 5 is a schematic flowchart of a communication method according to an embodiment of the present application. The method in FIG. 5 is applied to a communication system, for example, the communication system shown in FIG. 1, FIG. 2 or FIG. 3. The network device in FIG. 5 is, for example, the network device 110 in FIG. 1, the core network device in FIG. 2, the access network node in FIG. 3. The terminal device in FIG. 5 is, for example, the terminal device in FIG. 1, FIG. 2 or FIG. 3. The method in FIG. 5 comprises the following steps.

[0152] S510, configure a first reference signal resource set for the terminal device. Correspondingly, the terminal device determines the first reference signal resource set. Step S510 is similar to step S401, and thus is not described here.

[0153] Optionally, before step S520, the terminal device performs step S501.

[0154] S501, send third indication information to the network device. Correspondingly, the network device receives the third indication information. The third indication information is used to indicate that the first model is a regression model. The first model is used to determine a predicted value of channel state information corresponding to each reference signal resource in a second reference signal resource set. The first model is an AI model. The second reference signal resource set is described in step S420.

[0155] The present embodiment does not limit the order of performing steps S510 and S501. For example, step S510 can be performed first, and then step S501. Alternatively, step S501 can be performed first, and then step S510.

[0156] S520, determine the first confidence. The specific implementation manner is described in steps S410-S430 in FIG. 4, and thus is not described here.

[0157] S530, determine the first report according to the first confidence.

[0158] Optionally, the first report is used to indicate an index of each reference signal resource in a third reference signal resource set. Alternatively, the first report is used to indicate the index of each reference signal resource in the third reference signal resource set and the first confidence. Alternatively, the first report is used to indicate the index of each reference signal resource in the third reference signal resource set, a predicted value of channel state information corresponding to each reference signal resource in the third reference signal resource set, and the first confidence. The third reference signal resource set includes at least one reference signal resource. The second reference signal resource set includes the third reference signal resource set, that is, the third reference signal resource set is a subset of the second reference signal resource set. The predicted value of channel state information corresponding to the reference signal resource in the third reference signal resource set is greater than or equal to the predicted value of channel state information corresponding to the reference signal resource in the second reference signal resource set except the third reference signal resource set.

[0159] It should be understood that the third reference signal resource set can be a virtual set. In other words, the network device can not configure the third reference signal resource set for the terminal device.

[0160] Optionally, the terminal device determines the first report according to a preset condition and the first confidence level. For example, when the first confidence level satisfies the preset condition, the first report is determined. The first report is used to indicate the index of each reference signal resource in the third reference signal resource set, the predicted value of the channel state information corresponding to each reference signal resource in the third reference signal resource set, and the first confidence level. When the first confidence level does not satisfy the preset condition, the first report is determined. The first report is used to indicate the index of each reference signal resource in the third reference signal resource set, or the first report is used to indicate the index of each reference signal resource in the third reference signal resource set and the first confidence level.

[0161] In some embodiments, the first confidence level satisfying the preset condition indicates that the predicted value of the channel state information corresponding to the third reference signal resource set is highly reliable, or the predicted value of the channel state information corresponding to the third reference signal resource set is reliable. Correspondingly, the first confidence level not satisfying the preset condition indicates that the predicted value of the channel state information corresponding to the third reference signal resource set is less reliable, or the predicted value of the channel state information corresponding to the third reference signal resource set is unreliable.

[0162] Optionally, the preset condition includes at least one of the following: a difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a first preset threshold, the difference includes at least one of the following: a mean value of the difference, a variance of the difference, or a standard deviation of the difference; or a difference between the mean value of the measured value and the mean value of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a second preset threshold; or a difference between the variance of the measured value and the variance of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a third preset threshold; or a difference between the standard deviation of the measured value and the standard deviation of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a fourth preset threshold; or a difference between the maximum value x and the minimum value y in the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a fifth preset threshold. The embodiments of the present application do not limit the specific values of the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, and the fifth preset threshold. At least two of the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, and the fifth preset threshold are the same or different.

[0163] Exemplarily, when the first confidence level indicates a difference or a distribution of differences between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, if the distribution of differences between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a first preset threshold, it indicates that the first confidence level satisfies the preset condition. The distribution of differences includes at least one of the following: the mean of the differences, the variance of the differences, or the standard deviation of the differences. If the distribution of differences between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is greater than the first preset threshold, it indicates that the first confidence level does not satisfy the preset condition.

[0164] Exemplarily, when the first confidence level indicates a difference between the mean of the measured value and the mean of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, if the difference between the mean of the measured value and the mean of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a second preset threshold, it indicates that the first confidence level satisfies the preset condition. If the difference between the mean of the measured value and the mean of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is greater than the second preset threshold, it indicates that the first confidence level does not satisfy the preset condition.

[0165] Exemplarily, when the first confidence level indicates a difference between the variance of the measured value and the variance of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, if the difference between the variance of the measured value and the variance of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a third preset threshold, it indicates that the first confidence level satisfies the preset condition. If the difference between the variance of the measured value and the variance of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is greater than the third preset threshold, it indicates that the first confidence level does not satisfy the preset condition.

[0166] Exemplarily, when the first confidence level indicates a difference between the standard deviation of the measured value and the standard deviation of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, if the difference between the standard deviation of the measured value and the standard deviation of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a fourth preset threshold, it indicates that the first confidence level satisfies the preset condition. If the difference between the standard deviation of the measured value and the standard deviation of the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is greater than the fourth preset threshold, it indicates that the first confidence level does not satisfy the preset condition.

[0167] For example, when the first confidence level indicates the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, or when the first confidence level indicates the maximum value x and the minimum value y in the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set, if the difference between the maximum value x and the minimum value y in the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is less than or equal to a fifth preset threshold, it indicates that the first confidence level satisfies the preset condition. If the difference between the maximum value x and the minimum value y in the difference between the measured value and the predicted value of the channel state information corresponding to each reference signal resource in the first reference signal resource set is greater than the fifth preset threshold, it indicates that the first confidence level does not satisfy the preset condition.

[0168] For example, the distribution of the difference between the measured value and the predicted value being less than or equal to the first preset threshold includes that the distribution of the absolute value of the difference between the measured value and the predicted value is less than or equal to the first preset threshold. For example, the mean of the absolute value of the difference between the measured value and the predicted value is less than or equal to the first preset threshold. The variance of the absolute value of the difference between the measured value and the predicted value is less than or equal to the first preset threshold. The standard deviation of the absolute value of the difference between the measured value and the predicted value is less than or equal to the first preset threshold. Similarly, the mean of the measured value and the mean of the predicted value being less than or equal to the second preset threshold includes that the absolute value of the difference between the mean of the measured value and the mean of the predicted value is less than or equal to the second preset threshold. The difference between the variance of the measured value and the variance of the predicted value being less than or equal to the third preset threshold includes that the absolute value of the difference between the variance of the measured value and the variance of the predicted value is less than or equal to the third preset threshold. The difference between the standard deviation of the measured value and the standard deviation of the predicted value being less than or equal to the fourth preset threshold includes that the absolute value of the difference between the standard deviation of the measured value and the standard deviation of the predicted value is less than or equal to the fourth preset threshold. The difference between the maximum value x and the minimum value y being less than or equal to the fifth preset threshold includes that the absolute value of the difference between the maximum value x and the minimum value y is less than or equal to the fifth preset threshold.

[0169] In some embodiments, the preset condition is preconfigured. Alternatively, the preset condition is indicated by the network device.

[0170] For example, before step S530, the network device sends the first indication information to the terminal device. Correspondingly, the terminal device receives the first indication information from the network device. The first indication information is used to indicate the preset condition.

[0171] S540, sending the first report to the network device. Correspondingly, the network device receives the first report from the terminal device.

[0172] In a case that the first report is used to indicate the index of each reference signal resource in the third set of reference signal resources, the predicted value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources, and the first confidence level, or in a case that the first report is used to indicate the predicted value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources, the network device determines that the predicted value of the channel state information corresponding to the third set of reference signal resources is reliable. In a case that the first report does not indicate the predicted value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources, or in a case that the first report only indicates the index of each reference signal resource in the third set of reference signal resources, the network device determines that the predicted value of the channel state information corresponding to the third set of reference signal resources is unreliable.

[0173] Optionally, in a case that the first report does not indicate the predicted value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources, or in a case that the first report only indicates the index of each reference signal resource in the third set of reference signal resources, or in a case that the first report only indicates the index of each reference signal resource in the third set of reference signal resources and the first confidence level, the first network device performs step S550.

[0174] S550, the terminal device is configured with the third set of reference signal resources. Correspondingly, the terminal device receives the third set of reference signal resources from the network device.

[0175] In some embodiments, each reference signal resource in the third set of reference signal resources corresponds to a reference signal. The reference signal includes SSB and / or CSI-RS. The reference signal resource is, for example, a beam. In other words, the reference signal resource in the embodiments of the present application can be replaced by a beam.

[0176] In some embodiments, after the terminal device receives the third set of reference signal resources, the terminal device performs measurement according to the third set of reference signal resources to determine the measurement value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources.

[0177] Optionally, after the terminal device determines the measurement value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources, the terminal device performs step S560.

[0178] S560, the second report is sent to the network device. Correspondingly, the network device receives the second report from the terminal device. The second report is used to indicate the measurement value of the channel state information corresponding to each reference signal resource in the third set of reference signal resources.

[0179] In the embodiments of this application, after the terminal device determines the first confidence level, the terminal device can further determine a first report to be reported according to the first confidence level, so that the network device can determine whether the predicted value of the channel state information corresponding to the reference signal resource is reliable according to the content included in the first report after receiving the first report, thereby facilitating to improve the accuracy of predicting the channel state information corresponding to the reference signal resource.
