Description

Method and apparatus for communication

[0001] The present application claims priority to the Chinese patent application No. 202410905252.2, filed on July 5, 2024, entitled "Method and apparatus for communication", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] In a communication system, a network device can determine the related configuration information of a downlink channel, such as a resource of a downlink data channel, a modulation and coding scheme (MCS), and a precoding of the network device scheduling a terminal device, according to a downlink channel state information (CSI). The terminal device can calculate the downlink CSI by measuring a downlink reference signal, and generate a CSI report to feed back to the network device.

[0004] After introducing artificial intelligence (AI) into wireless communication, an AI-based CSI feedback mode appears. The AI model has stronger feature extraction capability, can more effectively compress channel information, reduce information loss in the compression process, and ensure the accuracy of the recovered channel information. In order to accurately evaluate the performance of the AI model, the performance of the AI model needs to be monitored, that is, to determine whether the AI model is working normally. If the AI model performance is poor, it needs to switch to a non-AI mode or replace or update the AI model.

[0005] However, the resource overhead required for monitoring the AI model is large.

[0120] By way of example and not limitation, in the embodiments of the present application, the terminal device can also be a wearable device. 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. The wearable device is not only a hardware device, but also a device that realizes powerful functions through software support and data interaction and cloud interaction. The general wearable smart device includes devices with full functions, large size, and the ability to realize complete or partial functions without relying on a smart phone, such as smart watches or smart glasses, and devices that focus on a certain application function and need to be used in cooperation with other devices, such as smart phones, such as various smart wristbands and smart jewelry for monitoring vital signs.

[0121] In the embodiments of the present application, the apparatus for implementing the function of the terminal device can be a terminal device, or an apparatus capable of supporting the terminal device to implement the function, for example, a chip system, which can be installed in the terminal device or used in matching with the terminal device. 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.

[0122] The network device in the embodiments of the present application can include a device for communicating with a terminal device, for example, the network device can include an access network device or a radio access network device, for example, the access network device can be a base station. The radio access network device in the embodiments of the present application can refer to a radio access network (RAN) node (or device) that accesses 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 that performs the function of a base station in D2D, V2X, M2M communication, a network side device in a future communication network, a device that performs the function of a base station in a future communication system, 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 the 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.

[0123] 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, a helicopter or a drone can be configured to serve as a device that communicates with another base station.

[0124] 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.

[0125] In some deployments, wireless access by terminals is assisted by cooperation of multiple RAN nodes, 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.

[0126] The RAN node can support one or more types of front-haul interfaces, and different front-haul interfaces respectively correspond to DUs and RUs with different functions.

[0127] If the front-haul interface between the DU and the RU is a common public radio interface (CPRI), the DU is configured to implement one or more of the baseband functions, and the RU is configured to implement one or more of the radio frequency functions.

[0128] If the front-haul interface between the DU and the RU is another interface, compared with the CPRI, part of the baseband functions of the downlink and / or the uplink, such as one or more of precoding, digital beamforming (BF), or inverse fast Fourier transform (IFFT) / adding a cyclic prefix (CP) for the downlink, or one or more of digital BF, or fast Fourier transform (FFT) / removing the CP for the uplink, are moved from the DU to the RU for implementation.

[0129] One possible implementation, the interface can be an 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.

[0130] Taking eCPRI Cat A as an example, for downlink transmission, the DU is configured to implement layer mapping and one or more functions before layer mapping (i.e., one or more of encoding, rate matching, scrambling, modulation, layer mapping), while other functions after layer mapping (e.g., one or more of resource element (RE) mapping, digital BF, or inverse fast Fourier transform (IFFT) / adding CP) are implemented in the RU. For uplink transmission, the DU is configured to implement demapping and one or more functions before demapping (i.e., one or more of decoding, de-rate matching, de-scrambling, de-modulation, inverse discrete Fourier transform (IDFT), channel equalization, de-RE mapping), while other functions after demapping (e.g., one or more of digital BF or FFT / CP removal) are implemented in the RU. It can be understood that the description of the functions of the DU and the RU corresponding to various types of eCPRI can refer to the eCPRI protocol, which is not described here.

[0131] In one 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.

[0132] 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 an open RAN (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.

[0133] 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 combination 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 in this way.

[0134] The network device and / or the terminal device can be deployed on land, including indoors, outdoors, handheld, and / or vehicle-mounted; can also be deployed on water (such as a ship, etc.); and can also be deployed in the air (such as an airplane, a balloon, and / or a satellite). The scenario in which the network device and the terminal device are located is not limited in the embodiments of the present application.

[0135] In addition, the terminal device and the network device can be a hardware device, or can be a software function running on a special hardware, a software function running on general hardware, such as a virtualized function instantiated on a platform (for example, a cloud platform), or an entity including a special or general hardware device and a software function. The specific form of the terminal device and the network device is not limited in the present application.

[0136] In a wireless communication network, for example, in a mobile communication network, the services supported by the network are increasingly diverse, and therefore the needs to be met are increasingly diverse. For example, the network needs to be able to support ultra-high rates, ultra-low latencies, and / or ultra-large connections. This feature makes network planning, network configuration, and / or resource scheduling increasingly complex. In addition, as the functions of the network become increasingly powerful, for example, supporting increasingly high frequency spectrums, supporting high-order multiple input multiple output (MIMO) technology, supporting beamforming, and / or supporting new technologies such as beam management, network energy saving has become a hot research topic. These new needs, 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 intelligentization.

[0137] In order to support AI technology in the wireless network, an AI node (which can also be referred to as an AI entity) can also be introduced into the network.

[0138] Optionally, the AI entity 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, etc., or the AI entity can also be deployed separately, for example, in a position other than any of the above-mentioned devices, such as a host or a cloud server of an over the top (OTT) system. The AI entity 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, etc. Based on the object served by the AI entity, the AI entity can include an AI entity on the network device side, an AI entity on the terminal device side, or an AI entity on the core network side.

[0139] It can be understood that the present application does not limit the number of AI entities. For example, when there are multiple AI entities, the multiple AI entities can be divided based on functions, such as different AI entities being responsible for different functions.

[0140] It can also be understood that the AI entity can be a separate device, can be integrated into the same device to implement different functions, or can be a network element in a hardware device, can be a software function running on a dedicated hardware, or can be a virtualized function instantiated on a platform (e.g., a cloud platform), and the present application does not limit the specific form of the AI entity.

[0141] The AI entity can be an AI network element or an AI module. The AI entity is used to implement a corresponding AI function. The AI modules deployed in different network elements can be the same or different. The AI model in the AI entity can implement different functions according to different parameter configurations. The AI model in the AI entity can be configured based on one or more of the following parameters: a structural parameter (such as at least one of the number of neural network layers, the width of the neural network, the connection relationship between layers, the weight of a neuron, the activation function of a neuron, or the bias in the activation function), an input parameter (such as the type of the input parameter and / or the dimension of the input parameter), or an output parameter (such as the type of the output parameter and / or the dimension of the output parameter). The bias in the activation function can also be referred to as the bias of the neural network.

[0142] One AI entity can have one or more models. One model can infer an output, which includes one parameter or multiple parameters. The learning process, the training process, or the inference process of different models can be deployed in different entities or devices, or can be deployed in the same entity or device.

[0143] FIG. 1 is a schematic diagram of a communication system applicable to the communication method according to the embodiments of the present application. As shown in FIG. 1, the communication system 100 can include at least one network device, such as the network device 110 shown in FIG. 1, and at least one terminal device, such as the terminal device 120 and the terminal device 130 shown in FIG. 1. The network device 110 and the terminal devices (such as the terminal device 120 and the terminal device 130) can communicate with each other through a wireless link. The communication devices in the communication system, such as the network device 110 and the terminal device 120, can communicate with each other through a multi-antenna technology.

[0144] FIG. 2 is a schematic diagram of another communication system applicable to the communication method according to the embodiments of the present application. Compared with the communication system 100 shown in FIG. 1, the communication system 200 shown in FIG. 2 further includes an AI network element 140. The AI network element 140 is configured to perform AI-related operations, such as constructing a training data set or training an AI model.

[0145] In a possible implementation, the network device 110 can send data related to the training of the AI model to the AI network element 140, and the AI network element 140 can construct a training data set and train an AI model. For example, the data related to the training of the AI model can include data reported by the terminal device. The AI network element 140 can send the result of the AI model-related operation to the network device 110 and forward it to the terminal device through the network device 110. For example, the result of the AI model-related operation can include at least one of the following: a trained AI model, an evaluation result or a test result of the model, and the like. For example, part of the trained AI model can be deployed on the network device 110, and the other part can be deployed on the terminal device. Alternatively, the trained AI model can be deployed on the network device 110. Alternatively, the trained AI model can be deployed on the terminal device.

[0146] It should be understood that FIG. 2 only illustrates the case that the AI network element 140 is directly connected to the network device 110, and in other scenarios, the AI network element 140 can also be connected to the terminal device. Alternatively, the AI network element 140 can be connected to both the network device 110 and the terminal device. Alternatively, the AI network element 140 can also be connected to the network device 110 through a third-party network element. The embodiments of the present application do not limit the connection relationship between the AI network element and other network elements.

[0147] The AI network element 140 can also be arranged as a module in the network device and / or the terminal device, such as the network device 110 or the terminal device shown in FIG. 1. One or more AI modules can be deployed in the network device 110. One or more AI modules can be deployed in the terminal device.

[0148] It should be noted that FIG. 1 and FIG. 2 are merely simplified schematic diagrams for the purpose of understanding, and other devices such as wireless relay devices and / or wireless backhaul devices can also be included in the communication system, which are not shown in FIG. 1 and FIG. 2. In actual applications, the communication system can include multiple network devices and / or multiple terminal devices. The number of network devices and terminal devices included in the communication system is not limited in the embodiments of the present application.

[0149] FIG. 3 is a schematic diagram of a possible application framework of a communication system according to an embodiment of the present application. As shown in FIG. 3, the network elements in the communication system are connected through interfaces (such as NG, Xn) or air interfaces. One or more AI modules (only one is shown in FIG. 3 for clarity) are arranged 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 an operation administration and maintenance (OAM) device. The access network node can be a single RAN node or can include multiple RAN nodes, such as 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 modules are arranged in the CU-CP and / or the CU-UP. For example, the CU and the DU are connected through an F1 interface. The CUs are connected through an Xn interface.

[0150] 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 device shown in FIG. 3. For example, the AI module can be a RIC shown in FIG. 4, such as a near-real-time RIC or a non-real-time RIC. For example, the near-real-time RIC is arranged in the RAN node (such as the CU, the CU-CP, the CU-UP, the DU, and / or the RU), and the non-real-time RIC is arranged 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 (such as the CU, the CU-CP, the CU-UP, the DU, and / or the RU), reorganize the subset of data 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 also be arranged as a single network element, respectively, and the network device can be the near-real-time RIC or the non-real-time RIC.

[0151] FIG. 4 is a schematic diagram of a possible application framework in a communication system. As shown in FIG. 4, the communication system includes a RAN intelligent controller (RIC). For example, the RIC can be the AI module shown in FIG. 3, 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 real-time RIC mainly processes near-real-time information, such as data that is relatively sensitive to latency, which is on the order of tens of milliseconds.

[0152] The near-real-time 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-real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (such as CUs, CU-CPs, CU-UPs, DUs, and / or RUs) and / or terminals. This information can be used as training data or inference data. Optionally, the near-real-time RIC can deliver inference results to RAN nodes and / or terminals. Optionally, inference results can be exchanged between CUs and DUs, and / or between DUs and RUs. For example, the near-real-time RIC delivers inference results to a DU, which then sends them to an RU.

[0153] The non-real-time RIC is also used for model training and inference. For example, it is used to train an AI model and perform inference using the model. The non-real-time RIC can obtain network-side and / or terminal-side information from RAN nodes (such as CUs, CU-CPs, CU-UPs, DUs, and / or RUs) and / or terminals. This information can be used as training data or inference data, and inference results can be delivered to RAN nodes and / or terminals. Optionally, inference results can be exchanged between CUs and DUs, and / or between DUs and RUs. For example, the non-real-time RIC delivers inference results to a DU, which then sends them to an RU.

[0154] The near-real-time RIC and the non-real-time RIC can also be separately set up as a network element. 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 can be set up in a RAN node (such as a CU or a DU), while the non-real-time RIC can be set up in an OAM, a cloud server, a core network device, or another network device.

[0155] To facilitate understanding of the schemes of the embodiments of the present application, the following explains the terms that can be involved in the embodiments of the present application.

[0156] (1) AI model:

[0157] An AI model is an algorithm or computer program that can implement an AI function. The AI model represents the mapping relationship between the input and output of the model. The AI model can be understood as a function model that maps a certain dimension of input to a certain dimension of output, and the model parameters are obtained through machine learning training. For example, f(x) = ax 2 +b is a quadratic function model, which can be regarded as an AI model, and a and b correspond to the parameters of the AI model, which can be obtained through machine learning training. The AI model can also be referred to as a model or an AI function or a function. One AI function can correspond to one or more AI models.

[0158] The type of AI model can be a neural network, a linear regression model, a decision tree model, a support vector machine (SVM), a Bayesian network, a Q-learning model, or other machine learning (ML) models.

[0159] (2) Two-end model:

[0160] The two-end model can also be referred to as a two-sided model, a collaborative model, a dual model, or a two-side model, etc. The two-end model refers to a model composed of multiple sub-models. The multiple sub-models constituting the model need to be matched with each other. The multiple sub-models can be deployed in different nodes.

[0161] The embodiments of the present application relate to an encoder for compressing channel information and a decoder for restoring channel information. The encoder and the decoder are matched for use, and it can be understood that the encoder and the decoder are a matched AI model. One encoder can include one or more AI models, and the decoder matched with the encoder also includes one or more AI models. The AI models included in the matched encoder and decoder are the same in number and one-to-one correspondence. The encoder can also include a quantization module, which can be used for quantization processing of the output of the AI model in the encoder. The decoder can include a dequantization module, which can be used for dequantization processing of the feedback information of the received channel information to obtain the input of the AI model in the decoder. The dequantization processing can also be referred to as dequantization processing.

[0162] In one possible design, a pair of matching encoder and decoder can be two parts of the same auto-encoder (AE). The encoder and the decoder are deployed in different nodes of the AE model, which is a typical bilateral model. The encoder and the decoder of the AE model are usually jointly trained. The auto-encoder is a kind of unsupervised learning neural network, which is characterized by taking the input data as the label data, and thus can also be understood as a self-supervised learning neural network. The auto-encoder can be used for data compression and recovery. For example, the encoder in the auto-encoder can compress (encode) the data A to obtain the data B, and the decoder in the auto-encoder can decompress (decode) the data B to recover the data A. Alternatively, it can be understood that the decoder is the inverse operation of the encoder.

[0163] FIG. 5 is a schematic diagram of the relationship between the encoder and the decoder. For example, as shown in FIG. 5, the encoder processes the input V to obtain the processed result z, and the decoder can decode the output z of the encoder to the expected output V’.

[0164] The AI model in the embodiments of this application can include an encoder deployed on the terminal device side and a decoder deployed on the network device side, or an encoder deployed on the terminal device side and a decoder deployed on another terminal device side, or an encoder deployed on the network device side and a decoder deployed on another network device side.

[0165] (3) Neural network (NN):

[0166] The neural network is a specific implementation form of AI or ML. According to the universal approximation theorem, the neural network can theoretically approximate any continuous function, so that the neural network has the ability to learn any mapping.

[0167] Taking the type of the AI model as the neural network as an example, the AI model involved in the present disclosure can be a deep neural network (DNN). The traditional communication system needs to rely on rich expert knowledge to design the communication module, while the deep learning communication system based on the DNN can automatically discover the implicit pattern structure from a large amount of data set, establish the mapping relationship between the data, and obtain better performance than the traditional modeling method.

[0168] A neural network can be composed of neurons, each of which performs a weighted sum operation on its input values and produces an output by passing the weighted sum result through a nonlinear function. A DNN generally has a multi-layer structure, each layer of the DNN can include multiple neurons, and the input layer transmits the values received after being processed by the neurons to the intermediate hidden layer. Similarly, the hidden layer transmits the calculation results to the final output layer to produce the final output of the DNN.

[0169] A DNN generally has more than one hidden layer, and the hidden layer often directly affects the ability to extract information and fit functions. Increasing the number of hidden layers of the DNN or expanding the width of each layer can improve the function fitting ability of the DNN. The weighted values in each neuron are the parameters of the DNN network model. The model parameters are optimized through a training process, so that the DNN network has the ability to extract data features and express mapping relationships. A DNN generally uses a supervised learning or unsupervised learning strategy to optimize model parameters.

[0170] Depending on the construction method of the network, the DNN can include a feedforward neural network (FNN), a convolutional neural network (CNN), and a recurrent neural network (RNN), etc.

[0171] A CNN is a neural network specially designed to process data with a grid-like structure. For example, time series data (discrete sampling on the time axis) and image data (two-dimensional discrete sampling) can be considered as data with a grid-like structure. Instead of using all input information at once for operation, a CNN uses a fixed-size window to extract part of the information for convolution operation, which greatly reduces the calculation amount of model parameters. In addition, different convolution kernels can be used for each window according to the different types of information extracted by the window (such as people and objects in the same image), which enables the CNN to better extract features of the input data.

[0172] A RNN is a DNN network that uses feedback time series information. Its input includes new input values at the current time and its own output values at the previous time. RNN is suitable for obtaining sequence features with temporal correlation, and is particularly suitable for speech recognition, channel coding and decoding, etc.

[0173] The FNN network is characterized by complete connection between neurons in adjacent layers, which requires a large amount of storage space and results in high computational complexity.

[0174] The FNN, CNN, and RNN are all constructed based on neurons. As described above, each neuron performs a weighted sum operation on its input values, and the weighted sum result generates an output through a nonlinear function. The weights of the weighted sum operation of the neurons in the neural network and the nonlinear function are referred to as parameters of the neural network. The parameters of all the neurons of a neural network constitute the parameters of the neural network.

[0175] (4) AI model design:

[0176] The AI model design mainly includes a data collection link (for example, collecting training data and / or inference data), a model training link, and a model inference link. Further, it can also include an inference result application link.

[0177] The training processes of different models can be deployed in different devices or nodes, or in the same device or node. The inference processes of different models can be deployed in different devices or nodes, or in the same device or node. For example, the terminal device can train a matching encoder and decoder, and then send the model parameters of the decoder to the network device. For example, the network device can train a matching encoder and decoder, and then indicate the model parameters of the encoder to the terminal device. For example, the AI network element can train a matching encoder and decoder, and then send the model parameters of the encoder to the terminal device and the model parameters of the decoder to the network device. Further, the terminal device can perform a model inference link corresponding to the encoder, and the network device can perform a model inference link corresponding to the decoder.

[0178] The model parameters can include one or more of the following: structural parameters (such as the number of layers and / or weights) of the model, input parameters (such as input dimension, input port number) of the model, or output parameters (such as output dimension, output port number) of the model. It can be understood that the input dimension can refer to the size of an input data, for example, when the input data is a sequence, the input dimension corresponding to the sequence can indicate the length of the sequence. The input port number can refer to the number of input data. Similarly, the output dimension can refer to the size of an output data, for example, when the output data is a sequence, the output dimension corresponding to the sequence can indicate the length of the sequence. The output port number can refer to the number of output data.

[0179] (5) Channel information:

[0180] In a communication system, a network device decides one or more of the following configurations of a downlink data channel of a terminal device based on channel information: resource, MCS, and precoding. It can be understood that the channel information, which can also be referred to as CSI or channel environment information, is information that can reflect channel characteristics and channel quality.

[0181] CSI measurement refers to solving channel information at a receiving end according to a reference signal sent by a sending end, that is, estimating channel information by using a channel estimation method. Exemplarily, the reference signal can include one or more of a channel state information reference signal (CSI-RS), a synchronizing signal / physical broadcast channel block (SSB), a sounding reference signal (SRS), or a demodulation reference signal (DMRS). One or more of the CSI-RS, the SSB, and the DMRS can be used to measure downlink channel information. The SRS and / or the DMRS can be used to measure uplink channel information.

[0182] Taking an FDD communication scenario as an example, because the uplink and downlink channels do not have reciprocity or cannot guarantee the reciprocity of the uplink and downlink channels, the network device needs to obtain the downlink CSI through uplink feedback of the terminal device. The network device usually sends a downlink reference signal to the terminal device, and the terminal device receives the downlink reference signal. Because the terminal device knows the sending information of the downlink reference signal, the terminal device can estimate (measure) the downlink channel experienced by the downlink reference signal according to the received downlink reference signal. The terminal device generates downlink CSI based on the measured downlink channel matrix. The terminal device generates a CSI report according to a protocol predefinition or a network device configuration, and feeds back the CSI report to the network device, so that the network device obtains the downlink CSI.

[0183] In the embodiments of the present application, the CSI has a broader meaning than that in the traditional scheme, and is not limited to CQI, precoding matrix indicator (PMI), rank indicator (RI), or CSI-RS resource indicator (CRI), but can also be one or more of channel response (such as a channel response matrix), a channel matrix, a channel feature matrix, a precoding matrix, RSRP, SINR, the identity (ID) of the optimal beam, or the ID of the top K beams, and the like. For example, the optimal beam can be the beam with the largest channel quality (for example, RSRP, SINR, etc.) in the beam set. The top K beams can be the K beams in the beam set whose channel quality (for example, RSRP, SINR, etc.) is greater than or equal to a certain threshold, or the top K beams in the order of descending channel quality, and K is a positive integer. The signal-to-interference-plus-noise ratio can also be referred to as the signal-to-noise ratio.

[0184] wherein RI is used to indicate the number of layers of the recommended downlink transmission for the receiving end of the reference signal, such as a terminal device, and CQI is used to indicate the modulation and coding scheme that can be supported by the current channel condition judged by the receiving end of the reference signal, such as a terminal device. PMI is used to indicate the recommended precoding for the receiving end of the reference signal, such as a terminal device. The number of layers of the precoding indicated by PMI corresponds to RI. The channel response and the channel matrix represent the channel itself, and the channel feature matrix and the precoding matrix are matrices composed of features extracted from the channel.

[0185] (6) Channel report:

[0186] The channel report can be used to reflect the channel measurement information or channel information corresponding to the reference signal (which can be used for channel measurement or channel estimation), or in other words, the channel report is information generated based on the information obtained by measuring the reference signal, which can reflect channel environment information, etc.

[0187] The channel report can also be replaced by a channel measurement report, or a measurement report, or a CSI report, or CSI feedback information, or CSI compression information, and the like, without being limited to other possible terms.

[0188] (7) Model monitoring:

[0189] Model monitoring refers to monitoring the performance of an AI model. If the AI model performs poorly, it can be switched to a non-AI mode, or replaced with a new AI model, or updated, etc. The performance of the AI model can be monitored by monitoring the accuracy of the AI model output or by monitoring the system performance. The accuracy of the AI model output can be referred to as an intermediate key performance indicator (intermediate KPI), i.e., an intermediate KPI. The system performance can also be referred to as an eventual KPI.

[0190] Specifically, monitoring the accuracy of the AI model output is to determine whether the performance of the AI model meets the requirements by comparing the difference between the output of the AI model and the corresponding label or ground-truth. Monitoring the system performance is to determine whether the performance of the AI model meets the requirements by monitoring whether the performance of the communication system after using the AI model meets the requirements.

[0191] The intermediate KPI can include one or more of generalized cosine similarity (GCS), square generalized cosine similarity (SGCS), or normalized mean square error (NMSE), etc. The eventual KPI can include throughput, spectral efficiency, transmission rate, block error rate (BLER), hypothetical BLER, hybrid automatic repeat request (HARQ) feedback, etc. The model monitoring can be performed by the UE or by the base station.

[0192] (8) Configuration type:

[0193] In the embodiments of the present application, the configuration type includes periodic configuration, semi-static configuration, and aperiodic configuration.

[0194] FIG. 6 is a schematic diagram of an example of the three configuration types in the embodiments of the present application.

[0195] Exemplarily, for a periodic configuration, as shown in (a) of FIG. 6, the network device configures a transmission period (for example, every 2 slots, that is, the transmission period is equal to 2 slots) and an offset (a slot offset within the period, for example, the offset is equal to 0) of the reference signal, and transmits the reference signal according to the transmission period and the offset of the reference signal. Wherein, the transmission period of the reference signal can be understood as the offset of adjacent reference signal resources, which can be simply referred to as the offset of adjacent resources.

[0196] Exemplarily, for a semi-static configuration, the network device configures a transmission period and an offset of the reference signal. Wherein, the network device can activate or deactivate the transmission of the reference signal through medium access control-control element (MAC-CE) and the like. For example, as shown in (b) of FIG. 6, the transmission of the reference signal on the first slot (from left to right) is activated through MAC-CE (the network device transmits the reference signal on the first slot and the third slot), the transmission of the reference signal on the fifth slot is deactivated through MAC-CE (indicated by a black box) (the network device does not transmit the reference signal on the fifth slot), and the transmission of the reference signal on the seventh slot is activated through MAC-CE (the network device can transmit the reference signal on the seventh slot and the ninth slot). That is, the configuration information of the semi-static configuration can include the transmission period of the reference signal, the number of transmissions, one or more activation information, and one or more deactivation information, etc. Wherein, the activation information or the deactivation information can be triggered by explicit signaling, such as the aforementioned MAC-CE signaling, or by a timer. Wherein, the duration of the counter can be predefined or configured.

[0197] Exemplarily, for aperiodic configuration, the network device indicates the resource for transmitting the reference signal through downlink control information (DCI) signaling. Wherein, as shown in (c) of FIG. 6, the network device can also configure multiple resource locations through parameters [m, k], m is the transmission period of the reference signal (for example, every 1 slot, that is, the transmission period is equal to 1 slot), that is, the interval of the multiple resources, k is the number of resources (which can also be understood as the number of transmissions of the reference signal) (for example, k = 4), and k is a positive integer. Wherein, the transmission period of the reference signal can be understood as the offset of adjacent reference signal resources, and the number of transmissions of the reference signal resources can be understood as the number of reference signal resources, which will not be described below.

[0198] After introducing AI into wireless communication, an AI-based CSI feedback mode appears. In order to accurately evaluate the performance of the AI model, that is, the performance of the AI-based CSI feedback, the performance of the AI model needs to be monitored.

[0199] However, the resource overhead required for monitoring the AI model is large.

[0200] Therefore, the present application provides a communication method and a communication device, which can reduce resource overhead.

[0201] It should be understood that, in the present application, the indication includes direct indication (also known as explicit indication) and implicit indication. Among them, the direct indication of information A means including the information A; the implicit indication of information A means indicating the information A by the corresponding relationship between the information A and the information B and the direct indication of the information B. The corresponding relationship between the information A and the information B can be predefined, pre-stored, pre-burned, or pre-configured.

[0202] It should be understood that, in the present application, the determination of information C for information D includes that information D is determined based on information C only, and information D is determined based on information C and other information. In addition, the determination of information C for information D can also include the case of indirect determination, such as the case that information D is determined based on information E, and information E is determined based on information C.

[0203] In addition, in the embodiments of the present application, "network element A sends information A to network element B" can be understood as that the destination of the information A or the intermediate network element in the transmission path between the destination is network element B, which can include direct or indirect sending of information to network element B. "Network element B receives information A from network element A" can be understood as that the source of the information A or the intermediate network element in the transmission path between the source is network element A, which can include direct or indirect receiving of information from network element A. The information can be processed as necessary between the source and the destination of the information sending, for example, format change, etc., but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly, and will not be described here.

[0204] In the scheme of the embodiments of the present application, "and / or" is used to describe the corresponding relationship of the corresponding objects, which means that there can be three kinds of relationships, for example, "A and / or B" can represent three cases of only A, only B and A and B existing at the same time, wherein A and B can be singular or plural.

[0205] FIG. 7 is a schematic flow chart of a communication method provided by the present application.

[0206] The method 800 shown in FIG. 7 can be applied in an AI-based CSI feedback scenario. Specifically, a two-end model is deployed on two devices to implement CSI feedback. The two-end model includes a first AI model and a second AI model. For example, the first AI model can be an AI model in an encoder, and the second AI model can be an AI model in a decoder. The first AI model can also be replaced by an encoder, and the second AI model can also be replaced by a decoder. That is, the model inference link corresponding to the encoder is performed in the device deploying the first AI model, and the model inference link corresponding to the decoder is performed in the device deploying the second AI model. The first AI model and the second AI model are matched.

[0207] The first AI model is used for CSI compression. The second AI model is used for CSI decompression. The CSI decompression can also be referred to as CSI reconstruction.

[0208] Alternatively, the first AI model is used for generation of CSI feedback information. The second AI model can be used for recovery of channel information corresponding to the CSI feedback information, i.e., to obtain CSI recovery information corresponding to the CSI feedback information. For example, the first AI model can be an encoder in FIG. 5, and the second AI model can be a decoder in FIG. 5.

[0209] The input of the first AI model can include a measurement result of a reference signal, i.e., a channel measurement result.

[0210] The reference signal can be one or more of a CSI-RS, an SSB, or a DMRS.

[0211] Specifically, the first AI model can be used to process the measurement result of the reference signal to obtain CSI feedback information corresponding to the reference signal; and the second AI model can be used to process the CSI feedback information corresponding to the reference signal to obtain CSI recovery information corresponding to the reference signal.

[0212] The terminal device side includes a terminal device, or other devices in communication with the terminal device, such as devices controlled by or serving the terminal device.

[0213] The first AI model is deployed on an AI entity at the terminal device side. The AI entity at the terminal device side can be the terminal device itself, or an AI entity in communication with the terminal device. For example, the AI entity can be a server, such as an OTT server or a cloud server.

[0214] The network device side includes a network device, or other devices in communication with the network device, such as devices controlled by or serving the network device.

[0215] The second AI model is deployed on an AI entity at the network device side. The AI entity at the network device side can be the network device itself, or an AI entity in communication with the network device. For example, the AI entity can be a RIC, an OAM or a server, such as an OTT server or a cloud server. The near-real-time RIC is arranged in a RAN node, for example, in a CU / DU. The RIC, the OAM or the server, and the like can be collectively referred to as an intelligent network element.

[0216] As shown in FIG. 7, the method 800 can include the following steps.

[0217] 810, the terminal device receives a first reference signal from the network device. The first reference signal has no precoding information.

[0218] 820, the terminal device receives a second reference signal from the network device, the second reference signal corresponding to the first precoding information.

[0219] 830, the terminal device determines at least one value of one or more first parameters and performance monitoring information of the first AI model and / or the second AI model according to a measurement result of the first reference signal and a measurement result of the second reference signal. The first parameters are related to channel quality.

[0220] Further, the method 800 can further include step 840.

[0221] 840, the terminal device sends a first CSI report to the network device, the first CSI report indicating at least one value of one or more first parameters and performance monitoring information.

[0222] The value of the first parameter and the performance monitoring information can be indicated by the same CSI report (such as the first CSI report). The same CSI report can be understood as a CSI report configured by configuration information carried in the same downlink signaling, or an identifier corresponding to the same information used to configure the CSI report.

[0223] For ease of description, in the embodiments of the present application, the "at least one value of one or more first parameters" is simply referred to as "value of the first parameter".

[0224] In the scheme of the embodiments of the present application, the same CSI report can be used to report the value of the first parameter and the performance monitoring information, which is beneficial to reduce the signaling overhead required for configuring the CSI report, i.e., to save the configuration overhead. Meanwhile, reporting the value of the first parameter and the performance monitoring information in the same CSI report is also beneficial to reduce the feedback overhead. For example, when the value of the first parameter and the performance monitoring information are reported in two CSI reports reported at different time instants, each CSI report includes corresponding packet header and other packet grouping information. In the scheme of the embodiments of the present application, the same CSI report is used for reporting, which is beneficial to reduce the feedback overhead of the common part (such as the packet header and other packet grouping information) of the CSI report.

[0225] The first reference signal can be referred to as a non-precoded reference signal, a reference signal without precoding information loading, or a reference signal without precoding information.

[0226] The "reference signal without precoding information loading" and the "reference signal with precoding information loading" can be understood as relative concepts. The reference signal without precoding information loading (the reference signal without precoding information loading) means that the reference signal is not processed using precoding information. The reference signal with precoding information loading (the reference signal with precoding information loading) can be understood as a reference signal processed using precoding information, i.e., precoding information is loaded on the reference signal.

[0227] Exemplarily, the reference signal in the embodiments of the present application can be a CSI-RS, an SSB, or a DMRS. For ease of description, the CSI-RS is mainly taken as an example for description in the embodiments of the present application. For example, the first reference signal can be a non-precoded CSI-RS, and the second reference signal can be a precoded CSI-RS. In other possible implementation manners, the CSI-RS can also be replaced by other types of reference signals.

[0228] The first precoding information is exemplarily described below.

[0229] Further, before step 820, the method 800 can further include step 811 (not shown in the figure).

[0230] 811. The terminal device sends, to the network device, CSI feedback information corresponding to the first reference signal, the CSI feedback information corresponding to the first reference signal being based on a measurement result of the first reference signal. The CSI feedback information corresponding to the first reference signal can be used for determination of the first precoding information.

[0231] For ease of description, in the embodiments of the present application, the CSI feedback information corresponding to the first reference signal can also be referred to as first CSI feedback information.

[0232] The network device can load the first precoding information on the reference signal to obtain a second reference signal, and send it to the terminal device. In this case, the precoding information loaded on the second reference signal is the precoding information based on the first CSI feedback information.

[0233] The first CSI feedback information can be the output of the first AI model or based on the output of the first AI model, and the input of the first AI model can be the measurement result of the first reference signal. The input of the second AI model can include the first CSI feedback information or based on the first CSI feedback information, and the output of the second AI model can be the recovery information of the channel information corresponding to the first CSI feedback information, i.e. the first CSI recovery information.

[0234] The first CSI feedback information can be used for determination of the first precoding information, i.e. the first CSI recovery information can be used for determination of the first precoding information. The reference signal loaded with the first precoding information can also be replaced by the reference signal loaded with the first CSI recovery information.

[0235] Optionally, the first CSI feedback information can be a second CSI report, or included in the second CSI report. The second CSI report can be configured by the configuration information of the second CSI report, such as the configuration of the time-frequency resource of the second CSI report by the configuration information of the second CSI report.

[0236] In addition, the precoding information corresponding to the second reference signal, i.e. the first precoding information, can also be determined based on other CSI feedback information in addition to the first CSI feedback information.

[0237] Whether the reference signal corresponds to the precoding information can be indicated by the network device to the terminal device.

[0238] Further, the method 800 can further include steps 801 and 802 (not shown in the figure).

[0239] 801, the terminal device receives first indication information from the network device. The first indication information indicates that the first reference signal has no precoding information.

[0240] 802, the terminal device receives second indication information from the network device. The second indication information indicates that the second reference signal corresponds to the first precoding information.

[0241] Alternatively, the method 800 can further include step 803 (not shown in the figure).

[0242] 803, the terminal device receives third indication information from the network device. The third indication information indicates that the first reference signal corresponds to no precoding information and the second reference signal corresponds to first precoding information.

[0243] The network device can send indication information to the terminal device to inform the terminal device whether the reference signal corresponds to precoding information.

[0244] Whether the reference signal corresponds to precoding information can be indicated in various ways.

[0245] Suppose field #1 in the indication information (such as the first indication information, the second indication information, and / or the third indication information) is used to indicate whether the reference signal corresponds to precoding information. The reference signal corresponding to precoding information and no precoding information can be distinguished by different values on field #1.

[0246] For example, the value on field #1 used to indicate that the reference signal corresponds to precoding information and no precoding information can be predefined.

[0247] For example, if the value of field #1 is 0, the reference signal has no precoding information, and if the value of field #1 is 1, the reference signal corresponds to precoding information.

[0248] For example, the value on field #1 used to indicate that the reference signal corresponds to precoding information can be predefined. If the value on field #1 is not the predefined value, the reference signal has no precoding information. The predefined value can also be used for precoding information determination. That is, the terminal device can determine which precoding information the reference signal corresponds to according to the value on field #1, or determine that the precoding information corresponding to the reference signal is based on which reference signal.

[0249] For example, field #1 can include 4 bits, where 0-10 are predefined values and can be used for precoding information determination. If the value on field #1 is any value in 0-10, the reference signal corresponds to precoding information, and if the value on field #1 is any value in 11-15, the reference signal has no precoding information.

[0250] Optionally, the method 800 can further include the following steps:

[0251] The terminal device receives first resource configuration information, and the first resource configuration information indicates resource configuration of the first reference signal;

[0252] The terminal device receives second resource configuration information, and the second resource configuration information indicates resource configuration of the second reference signal.

[0253] The first resource configuration information and the second resource configuration information are different resource configuration information.

[0254] Exemplarily, the first resource configuration information and the second resource configuration information can be carried in different messages.

[0255] As another possible implementation, the first reference signal and the second reference signal can be configured by one resource configuration information.

[0256] Optionally, the method 800 can further include the following steps:

[0257] The terminal device receives third resource configuration information, the third resource configuration information indicating the resource configuration of the first reference signal and the resource configuration of the second reference signal.

[0258] For example, different fields of the third resource configuration information can respectively indicate the resource configuration of the first reference signal and the resource configuration of the second reference signal.

[0259] Optionally, the resource configuration of the reference signal can include information about whether the reference signal corresponds to precoding information. That is, the resource configuration of the reference signal can indicate whether the reference signal corresponds to precoding information. In this case, the first resource configuration information can also be regarded as the first indication information, and the second resource configuration information can also be regarded as the second indication information. Alternatively, the third resource configuration information can also be regarded as the third indication information.

[0260] Further, the resource configuration of the reference signal can further include at least one of the following: a configuration type, an offset of adjacent resources, or a transmission times.

[0261] Exemplarily, the configuration type of the first reference signal can be periodic configuration, semi-static configuration or aperiodic configuration.

[0262] Exemplarily, the configuration type of the second reference signal can be periodic configuration, semi-static configuration or aperiodic configuration.

[0263] Exemplarily, the offset of adjacent resources can also be replaced by a transmission period. The resource configuration can further include an offset within the transmission period.

[0264] The unit of "offset" in the embodiments of the present application can be any one or more of the following: time slot, subframe, frame, orthogonal frequency division multiplexing (OFDM) symbol, millisecond, etc.

[0265] Optionally, the resource configuration of the reference signal can also not include information about whether the reference signal corresponds to precoding information. In this case, the first resource configuration information and the first indication information can be different information, and the second resource configuration information and the second indication information can be different information. The third resource configuration information and the third indication information can be different information.

[0266] The resource configuration information (such as the first resource configuration information, the second resource configuration information, and / or the third resource configuration information) can be carried in radio resource control (RRC) and activated by MAC CE or DCI, or carried in MAC CE, or carried in MAC CE and activated by DCI, or carried in RRC.

[0267] The first parameter is described below.

[0268] Optionally, the first parameter can include at least one of the following: CQI, SINR, SNR, RSRP, signal strength, interference level, adjustment amount of CQI, adjustment amount of SINR, adjustment amount of SNR, adjustment amount of RSRP, adjustment amount of signal strength, or adjustment amount of interference level, etc.

[0269] The above-mentioned "adjustment amount" can also be replaced by "change amount".

[0270] Exemplarily, the value of the first parameter indicated by the first CSI report indication can include a second value of parameter #1. Further, the value of the first parameter indicated by the first CSI report indication can include a first value of parameter #1. The first value of parameter #1 is determined according to the measurement result of the first reference signal. The second value of parameter #1 is determined according to the measurement result of the second reference signal.

[0271] Parameter #1 can include at least one of the following: CQI, SINR, SNR, RSRP, signal strength, or interference level.

[0272] Taking parameter #1 including CQI as an example, the terminal device can determine a first value of CQI according to the measurement result of the first reference signal, and determine a second value of CQI according to the measurement result of the second reference signal. For example, the first CSI report can indicate the second value of CQI. Or, the first CSI report can indicate the first value and the second value of CQI.

[0273] Exemplarily, the value of the first parameter indicated by the first CSI report indication can include a value of parameter #2. Parameter #2 can be an adjustment amount of parameter #1, and the value of parameter #2 can be based on the difference between the first value of parameter #1 and the second value of parameter #1.

[0274] For example, the terminal device can determine a first value of the CQI according to the measurement result of the first reference signal, determine a second value of the CQI according to the measurement result of the second reference signal, and determine a value of the adjustment amount of the CQI according to the difference between the second value of the CQI and the first value of the CQI. For example, the value of the adjustment amount of the CQI can be the difference between the second value of the CQI and the first value of the CQI.

[0275] Further, the value of the parameter #2 can be used to adjust a third value of the parameter #1.

[0276] For example, the third value of the parameter #1 can be understood as other values of the parameter #1 other than the first value and the second value. For example, the third value of the parameter #1 can be determined based on the measurement result of the reference signal without precoding information.

[0277] The third value is exemplarily described below.

[0278] Further, the method 800 can further include steps 850 and 860 (not shown in the figure).

[0279] 850, the terminal device receives a third reference signal from the network device. The third reference signal has no precoding information.

[0280] 860, the terminal device determines a third value of the parameter #1 based on the measurement result of the third reference signal.

[0281] Optionally, the value of the parameter #2 can be used to adjust the third value of the parameter #1 to obtain a fourth value of the parameter #1.

[0282] For example, the fourth value can be the difference or sum between the third value and the value of the parameter #2. For example, the parameter #1 is CQI, and the parameter #2 is the adjustment amount of the CQI. For example, the first value is CQI1, the second value is CQI2, the third value is CQI3, and the fourth value is CQI3'. The value of the adjustment amount of the CQI, delta(CQI), can be the result of CQI1 minus CQI2, i.e. delta(CQI) = CQI1-CQI2, in which case CQI3' = CQI3-delta(CQI). For another example, delta(CQI) can be the result of CQI2 minus CQI1, i.e. delta(CQI) = CQI1-CQI2, in which case CQI3' = CQI3+delta(CQI).

[0283] For example, the adjustment of the value of the parameter #1 can be performed by the terminal device or by the network device.

[0284] As an example, the terminal device can adjust the third value of parameter #1 according to the value of parameter #2 to obtain a fourth value of parameter #1, and send it to the network device.

[0285] As another example, the terminal device can send a third CSI report to the network device, the third CSI report indicating the third value of parameter #1. The network device can adjust the third value of parameter #1 according to the value of parameter #2 to obtain a fourth value of parameter #1.

[0286] Whether the third reference signal corresponds to the precoding information can be indicated by the indication information from the network device. The specific description of the indication information can refer to the first indication information, the second indication information or the third indication information described above. Here, no longer repeat.

[0287] The calculation process of the value of the first parameter is exemplarily described below taking CQI as an example.

[0288] FIG. 8 shows an example of the calculation process of CQI.

[0289] As shown in FIG. 8, the method 900 can include the following steps.

[0290] A1, the terminal device receives the CSI-RS (an example of the first reference signal) without precoding information sent by the network device to obtain the measurement result of the CSI-RS, such as the equivalent channel estimation result H1 in FIG. 8.

[0291] For example, H1 = H. H can represent a channel matrix.

[0292] A2, the terminal device calculates the value of SINR according to the equivalent channel estimation result H1 and the interference and noise level.

[0293] A3, the terminal device determines the corresponding value CQI1 of CQI based on the value of SINR, i.e., non-precoded CSI-RS-based CQI. Wherein, the corresponding value CQI1 of CQI based on the value of SINR can be determined through an algorithm, a formula, or a corresponding relationship between the two, and the specific determination manner is not limited here.

[0294] A4, the terminal device sends the CSI feedback information corresponding to the equivalent channel estimation result H1 (i.e., the first CSI feedback information) to the network device.

[0295] For example, the equivalent channel estimation result H1 is compressed through the first AI model to obtain the CSI feedback information.

[0296] A5, the network device determines precoding information V1 (first precoding information) according to the CSI feedback information.

[0297] The network device can load the precoding information V1 on the CSI-RS, that is, perform precoding processing on the CSI-RS by using the precoding information V1 to obtain the precoded CSI-RS (an example of the second reference signal).

[0298] For example, the CSI feedback information is reconstructed by the second AI model to obtain CSI recovery information, and the precoding information V1 corresponding to the CSI recovery information is loaded on the downlink reference signal, such as the CSI-RS.

[0299] A6, the terminal device receives the precoded CSI-RS with the precoding information V1 sent by the network device to obtain the measurement result of the CSI-RS, such as the equivalent channel estimation result H2 in FIG. 8.

[0300] A7, the terminal device calculates the value of the SINR according to the equivalent channel estimation result H2 and the interference and noise level.

[0301] A8, the terminal device determines the value CQI2 of the corresponding CQI based on the value of the SINR, that is, the precoded CSI-RS-based CQI.

[0302] Exemplarily, the first parameter can include CQI, and the value of the first parameter indicated by the first CSI report can include CQI2. The value of the first parameter indicated by the first CSI report can also include CQI1.

[0303] Exemplarily, the first parameter can include the adjustment amount of CQI. The value of the first parameter indicated by the first CSI report can include the value delta(CQI) of the adjustment amount of CQI, for example, delta(CQI) = CQI2-CQI1.

[0304] Further, the terminal device can adjust the CQI based on the value of the adjustment amount of CQI. Alternatively, the network device can adjust the CQI based on the value of the adjustment amount of CQI.

[0305] In the above scheme, the equivalent channel estimation result H2 measured by the terminal device based on the precoded CSI-RS with the precoding information V1 contains the reconstructed channel information, for example, H 2＝ V1*H. In this case, the CQI calculated by the terminal device is closer to the actual downlink channel quality.

[0306] It should be understood that the above is only one example of calculating the CQI according to the first reference signal and the second reference signal, and does not limit the manner of calculating the CQI.

[0307] According to the scheme of the embodiments of the present application, the value of the adjustment amount of the parameter can be used to adjust the value of the parameter, which is beneficial to make the adjusted value of the parameter more accurately reflect the downlink channel quality, thereby being beneficial to make the network device obtain more accurate channel quality to guarantee the communication performance. At the same time, it is beneficial to reduce the time required to obtain a more accurate value of the parameter, thereby being beneficial to guarantee the communication performance.

[0308] Optionally, the performance monitoring information can include a result of performance monitoring and / or information used to determine the result of performance monitoring.

[0309] The result of performance monitoring can be determined by the terminal device or by the network device.

[0310] For example, the terminal device can determine the result of performance monitoring. Further, the terminal device can report the result of performance monitoring to the network device.

[0311] For another example, the terminal device can report information used to determine the performance result to the network device, and the network device determines the result of performance monitoring.

[0312] It should be understood that the network device can directly determine the result of performance monitoring according to the information used to determine the performance result reported by the terminal device. Alternatively, the network device can also indirectly determine the result of performance monitoring according to the information used to determine the performance result reported by the terminal device. For example, the network device can determine one or more intermediate quantities according to the information used to determine the performance result reported by the terminal device, and then determine the result of performance monitoring according to the one or more intermediate quantities.

[0313] Exemplarily, the information used to determine the result of performance monitoring can include a first value of a second parameter and a second value of the second parameter, and / or a comparison result of the first value of the second parameter and the second value of the second parameter. The second parameter is a parameter related to performance monitoring. For example, the second parameter can include at least one of the following: CQI or SINR.

[0314] The first value of the second parameter can be determined according to a measurement result of the first reference signal. The second value of the second parameter can be determined according to a measurement result of the second reference signal. The first value of the second parameter and the second value of the second parameter can be used for performance monitoring of the first AI model and / or the second AI model, or in other words, for determining the result of performance monitoring.

[0315] Exemplarily, the comparison result of the first value of the second parameter and the second value of the second parameter is used to determine the result of performance monitoring.

[0316] For example, the terminal device can determine the performance monitoring result according to a comparison result of the first value of the second parameter and the second value of the second parameter. Further, the terminal device can report the performance monitoring result to the network device.

[0317] For another example, the terminal device can report the comparison result of the first value of the second parameter and the second value of the second parameter to the network device. The network device can determine the performance monitoring result according to the comparison result.

[0318] The performance monitoring result can be expressed in various forms.

[0319] For example, the performance monitoring result of the model can include that the model meets the performance requirement, or that the model does not meet the performance requirement. Whether the first AI model and / or the second AI model meets the performance requirement can be determined according to the measurement result of the first reference signal and the measurement result of the second reference signal.

[0320] For another example, the performance monitoring result of the model can include the performance level of the model. The performance level can also be replaced by the performance level. The performance of the model can be divided into multiple levels, i.e., multiple performance levels. According to the measurement result of the first reference signal and the measurement result of the second reference signal, it can be determined which performance level the performance of the first AI model and / or the second AI model belongs to.

[0321] The performance monitoring process is exemplarily described below taking the second parameter as SINR as an example.

[0322] FIG. 9 shows an example of the performance monitoring process.

[0323] As shown in FIG. 9, the method 1000 can include the following steps.

[0324] B1, the terminal device receives the CSI-RS (an example of the first reference signal) without precoding information sent by the network device to obtain the measurement result of the CSI-RS, such as the equivalent channel estimation result H1 in FIG. 9.

[0325] B2, the terminal device sends the CSI feedback information (i.e., the first CSI feedback information) corresponding to the equivalent channel estimation result H1 to the network device.

[0326] B3, the terminal device calculates the value SINR1 of SINR according to the equivalent channel estimation result H1, the precoding matrix V2, and the interference and noise level. The precoding matrix V2 is obtained by a non-AI manner according to the equivalent channel estimation result H1.

[0327] B4, the network device determines the precoding information V1 (an example of the first precoding information) according to the CSI feedback information.

[0328] The network device loads the precoding information V1 on the CSI-RS to obtain the CSI-RS (an example of a second reference signal) with the precoding information V1.

[0329] B5, the terminal device receives the CSI-RS with the precoding information V1 sent by the network device to obtain the measurement result of the CSI-RS, which is the equivalent channel estimation result H2 in FIG. 9.

[0330] B6, the terminal device calculates the value SINR2 of the SINR according to the equivalent channel estimation result H2 and the interference and noise level.

[0331] B7, the terminal device determines the result of the performance monitoring of the model based on SINR1 and SINR2.

[0332] Exemplarily, the result of the performance monitoring can include whether the performance of the CSI feedback by the first AI model and the second AI model is better than the performance of the non-AI feedback, so as to realize the performance monitoring of the model. For example, the terminal device can determine whether SINR1 and SINR2 satisfy the performance requirement in the performance monitoring (i.e., the performance requirement). For example, the performance requirement is that SINR2 is greater than SINR1. That is, if SINR2 is greater than SINR1, the performance of the CSI feedback by the first AI model and the second AI model is better than the performance of the non-AI feedback, which satisfies the performance requirement.

[0333] It should be understood that the above is only one example of the model monitoring according to the first reference signal and the second reference signal, and does not limit the specific implementation manner of the model monitoring. Exemplarily, the second parameter can be CQI, and the result of the performance monitoring can include whether the first AI model and / or the second AI model satisfies the performance requirement, so as to realize the performance monitoring of the model. For example, if CQI2 is greater than CQI1, the first AI model and / or the second AI model satisfies the performance requirement.

[0334] The network device can indicate the terminal device the first reference signal and the second reference signal for the value of the first parameter and the performance monitoring information in various manners.

[0335] The first reference signal and the second reference signal can also be referred to as a set of reference signal resource pairs. In other words, the network device can configure the terminal device the reference signal resource pairs for the value of the first parameter and the performance monitoring information in various manners.

[0336] The following takes scheme 1 and scheme 2 as examples for description.

[0337] Scheme 1 of configuring the terminal device the reference signal resource pairs for the value of the first parameter and the performance monitoring information:

[0338] In the scheme 1, the resource configuration of the reference signal can include information whether to be used for the determination of the value of the first parameter and the performance monitoring information. That is, the resource configuration of the reference signal can indicate whether the reference signal is used for the determination of the value of the first parameter and the performance monitoring information. The network device can indicate the terminal device whether the reference signal is used for the determination of the value of the first parameter and the performance monitoring information through the resource configuration information of the reference signal.

[0339] As a possible implementation manner, the first reference signal and the second reference signal can be configured by multiple resource configuration information.

[0340] For example, as described before, the resource configuration of the first reference signal can be indicated by the first resource configuration information. The resource configuration of the second reference signal can be indicated by the second resource configuration information.

[0341] Exemplarily, the value of the field #2 in the resource configuration information (such as the first resource configuration information and / or the second resource configuration information) can be used to indicate whether the reference signal can be used for the determination of the value of the first parameter and the performance monitoring information. The reference signal being used for the determination of the value of the first parameter and the performance monitoring information and not being used for the determination of the value of the first parameter and the performance monitoring information can be distinguished by different values on the field #2.

[0342] The value on the field #2 can be predefined. For example, the value of the field #2 is 0, then the reference signal is not used for the determination of the value of the first parameter and the performance monitoring information, and the value of the field #2 is 1, then the reference signal can be used for the determination of the value of the first parameter and the performance monitoring information.

[0343] Further, the resource configuration can also include other contents, and the specific description can be referred to the foregoing, which will not be described here again.

[0344] The terminal device determines the reference signal resource pair that can be used for the determination of the value of the first parameter and the performance monitoring information according to the first resource configuration information and the second resource configuration information, that is, determines that the first reference signal and the second reference signal can be used for the determination of the value of the first parameter and the performance monitoring information.

[0345] For example, the time offset of the first reference signal and the second reference signal is less than or equal to the first time length. The terminal device can determine the reference signal pair used for calculating the value of the first adjustment amount according to the first time length. The pair of the reference signal without precoding information and the reference signal with precoding information with the time offset less than or equal to the first time length can be used for calculating the value of the first adjustment amount. The first time length can be predefined or indicated by the network device.

[0346] FIG. 10(a) shows one example that the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is periodic configuration.

[0347] For example, as shown in (a) of FIG. 10, the first resource configuration information can indicate the following: the reference signal is periodically configured, the offset T1 of the adjacent resource of the reference signal, the non-precoding information of the reference signal, and the reference signal can be used for the determination of the first parameter value and the performance monitoring information; and the second resource configuration information can indicate the following: the reference signal is periodically configured, the offset T2 of the adjacent resource of the reference signal, the corresponding precoding information of the reference signal, and the reference signal can be used for the determination of the first parameter value and the performance monitoring information. The offset of the adjacent resource of the reference signal without precoding information and the offset of the adjacent resource of the reference signal with precoding information are shown in (a) of FIG. 10.

[0348] It should be understood that (a) of FIG. 10 is only an example and does not limit the scheme of the embodiments of the present application. For example, in (a) of FIG. 10, the second resource configuration information is sent after the first reference signal without precoding information, and in other implementation manners, the second resource configuration information can also be sent at other times.

[0349] (b) of FIG. 10 shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is aperiodic configuration.

[0350] For example, as shown in (b) of FIG. 10, the first resource configuration information can indicate the following: the reference signal is periodically configured, the offset T1 of the adjacent resource of the reference signal, the non-precoding information of the reference signal, and the reference signal can be used for the determination of the first parameter value and the performance monitoring information; and the second resource configuration information can indicate the following: the reference signal is aperiodically configured, the offset T2 of the adjacent resource of the reference signal, the number of times of sending the reference signal, the corresponding precoding information of the reference signal, and the reference signal can be used for the determination of the first parameter value and the performance monitoring information. As shown in (b) of FIG. 10, the offset of the adjacent resource of the reference signal without precoding information is T1, the offset of the adjacent resource of the reference signal with precoding information is T2, and the number of times of sending the reference signal with precoding information is twice.

[0351] It should be understood that (b) of FIG. 10 is only an example and does not limit the scheme of the embodiments of the present application. For example, in (b) of FIG. 10, the second resource configuration information is sent before the first reference signal without precoding information, and in other implementation manners, the second resource configuration information can also be sent at other times.

[0352] In FIG. 10, the reference signal is CSI-RS only as an example, and the reference signal can also be other types of reference signals.

[0353] As another possible implementation, the first reference signal and the second reference signal can be configured by the same resource configuration information.

[0354] Optionally, the same resource configuration information corresponds to an identity of the same resource configuration information. That is, the first reference signal and the second reference signal can be configured by the same resource configuration information, or can correspond to an identity of the same resource configuration information.

[0355] For example, as described above, the resource configuration of the first reference signal and the resource configuration of the second reference signal can be indicated by the third resource configuration information.

[0356] The description of the resource configuration can refer to the foregoing, which will not be repeated here.

[0357] The terminal device determines, according to the third resource configuration information, the reference signal resources that can be used for the determination of the value of the first parameter and the performance monitoring information, that is, determines the first reference signal and the second reference signal that can be used for the determination of the value of the first parameter and the performance monitoring information.

[0358] FIG. 11(a) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is periodic configuration.

[0359] For example, as shown in FIG. 11(a), the third resource configuration information can indicate the following: the first reference signal is periodic configuration, the offset T1 of the adjacent resources of the first reference signal, the first reference signal has no precoding information, the first reference signal can be used for the determination of the value of the first parameter and the performance monitoring information, the second reference signal is periodic configuration, the offset T2 of the adjacent resources of the second reference signal, the second reference signal corresponds to precoding information, and the second reference signal can be used for the determination of the value of the first parameter and the performance monitoring information. The offset of the adjacent resources of the reference signal without precoding information and the offset of the adjacent resources of the reference signal with precoding information are shown in FIG. 11(a).

[0360] FIG. 11(b) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is semi-static configuration.

[0361] For example, as shown in (b) of FIG. 11, the third resource configuration information can indicate the following: the first reference signal is periodically configured, the offset T1 of the adjacent resource of the first reference signal, the non-precoding information of the first reference signal, the first reference signal can be used for the determination of the value of the first parameter and the performance monitoring information, the second reference signal is semi-statically configured, the offset T2 of the adjacent resource of the second reference signal, the transmission times of the second reference signal, the precoding information corresponding to the second reference signal, and the second reference signal can be used for the determination of the value of the first parameter and the performance monitoring information. As shown in (b) of FIG. 11, the offset of the adjacent resource of the reference signal without precoding information is T1, the offset of the adjacent resource of the reference signal with precoding information is T2, and the transmission times of the reference signal with precoding information is twice.

[0362] In FIG. 11, the reference signal is CSI-RS only as an example, and the reference signal can also be other types of reference signals.

[0363] According to the scheme of the embodiment of the present application, the same reference signal resource is used for the determination of the value of the first parameter and the performance monitoring of the model, and the configuration of the reference signal resource can be multiplexed for the value of the first parameter and the performance monitoring of the model, which is beneficial to reduce the overhead of the reference signal resource, and is also beneficial to reduce the signaling overhead required for configuring the reference signal resource, that is, to save the overhead of the configuration.

[0364] Scheme 2 of configuring the reference signal resource pair for the value of the first parameter and the performance monitoring information of the terminal device:

[0365] In scheme 2, the network device can send indication information to the terminal device, and the indication information can be used to determine the reference signal resource pair for the determination of the value of the first parameter and the performance monitoring information.

[0366] Optionally, the method 800 can further include the following steps.

[0367] S21, the terminal device receives the fourth indication information from the network device, and the fourth indication information is used to determine that the first reference signal and the second reference signal are used for the determination of the value of the first parameter and the performance monitoring information.

[0368] Exemplarily, the fourth indication information can be trigger information, and the reference signal without precoding information and the reference signal with precoding information after the indication information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0369] As a possible implementation manner, the first reference signal and the second reference signal can be configured by multiple resource configuration information.

[0370] For example, as described above, the resource configuration of the first reference signal can be indicated by the first resource configuration information. The resource configuration of the second reference signal can be indicated by the second resource configuration information.

[0371] In scheme 2, the resource configuration of the reference signal can not include information about whether the reference signal is used for the determination of the value of the first parameter and the performance monitoring information.

[0372] For example, the resource configuration can include at least one of the following: a configuration type, an offset of adjacent resources, a number of transmissions, or whether it corresponds to precoding information.

[0373] Other descriptions of the resource configuration can refer to scheme 1, which will not be described here.

[0374] The terminal device determines, according to the fourth indication information, the reference signal resource pair that can be used for the determination of the value of the first parameter and the performance monitoring information, i.e., determines that the first reference signal and the second reference signal after the fourth indication information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0375] For example, the fourth indication information can be sent before the first resource configuration information and the second resource configuration information. For another example, the fourth indication information can be sent after the first resource configuration information and the second resource configuration information. For another example, the fourth indication information can be sent between the first resource configuration information and the second resource configuration information.

[0376] Figure 12(a) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is periodic configuration.

[0377] For example, as shown in Figure 12(a), the first resource configuration information can indicate the following: the reference signal is periodically configured, the offset T1 of the adjacent resources of the reference signal, and the reference signal has no precoding information. The second resource configuration information can indicate the following: the reference signal is periodically configured, the offset T2 of the adjacent resources of the reference signal, and the reference signal corresponds to precoding information. The offset of the adjacent resources of the reference signal without precoding information and the offset of the adjacent resources of the reference signal with precoding information are shown in Figure 12(a). In the scheme shown in Figure 12(a), the fourth indication information can be sent before the first resource configuration information and the second resource configuration information, and both the reference signal without precoding information configured by the first resource configuration information and the reference signal with precoding information configured by the second resource configuration information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0378] Figure 12(b) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is aperiodic configuration.

[0379] For example, as shown in (b) of FIG. 12, the fourth indication information can be transmitted after the transmission time of the part of the reference signal configured by the first resource configuration information and the transmission time of the part of the reference signal configured by the second resource configuration information. The first resource configuration information can indicate that the reference signal is periodically configured, the offset T1 of the adjacent resource of the reference signal, and the non-precoding information of the reference signal. The second resource configuration information can indicate that the reference signal is aperiodically configured, the offset T2 of the adjacent resource of the reference signal, the transmission times of the reference signal, and the precoding information corresponding to the reference signal. As shown in (b) of FIG. 12, the offset of the adjacent resource of the reference signal without precoding information is T1, the offset of the adjacent resource of the reference signal with precoding information is T2, and the transmission times of the reference signal with precoding information are twice. In the scheme shown in (b) of FIG. 12, before the fourth indication information is transmitted, the reference signal without precoding information configured by the first resource configuration information and the reference signal with precoding information configured by the second resource configuration information have already transmitted part of the reference signal. The reference signal after the fourth indication information in the reference signal without precoding information configured by the first resource configuration information and the reference signal with precoding information configured by the second resource configuration information can be used for the determination of the value of the first parameter and the performance monitoring information. That is, the reference signal before the fourth indication information in the reference signal without precoding information configured by the first resource configuration information and the reference signal with precoding information configured by the second resource configuration information is not used for the determination of the value of the first parameter and the performance monitoring information, and after the fourth indication information is received, the terminal device determines that the reference signal without precoding information after the fourth indication information configured by the first resource configuration information and the reference signal with precoding information after the fourth indication information configured by the second resource configuration information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0380] It should be understood that (a) and (b) of FIG. 12 are only examples and do not limit the scheme of the embodiments of the present application. For example, the first resource configuration information, the second resource configuration information, and the fourth indication information in FIG. 12 can be transmitted at other times.

[0381] In FIG. 12, the reference signal is CSI-RS only as an example, and the reference signal can also be other types of reference signals.

[0382] As another possible implementation, the first reference signal and the second reference signal can be configured by the same resource configuration information.

[0383] For example, as described above, the resource configuration of the first reference signal and the resource configuration of the second reference signal can be indicated by the third resource configuration information. The description of the resource configuration can refer to the related description in the foregoing scheme 2, which will not be described here again.

[0384] The terminal device determines, according to the fourth indication information, that the reference signal resources that can be used for the determination of the value of the first parameter and the performance monitoring information, that is, the first reference signal and the second reference signal after the fourth indication information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0385] For example, the fourth indication information can be sent before the third resource configuration information. For another example, the fourth indication information can be sent after the third resource configuration information.

[0386] FIG. 13(a) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is periodic configuration.

[0387] For example, as shown in FIG. 13(a), the third resource configuration information can indicate the following: the first reference signal is periodic configuration, the offset T1 of the adjacent resources of the first reference signal, the first reference signal has no precoding information, the second reference signal is periodic configuration, the offset T2 of the adjacent resources of the second reference signal, and the second reference signal corresponds to precoding information. The offset of the adjacent resources of the reference signal without precoding information and the offset of the adjacent resources of the reference signal with precoding information are shown in FIG. 13(a). In the scheme shown in FIG. 13(a), the fourth indication information is sent before the third resource configuration information, and both the reference signal without precoding information and the reference signal with precoding information configured by the third resource configuration information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0388] FIG. 13(b) shows one example in which the configuration type of the first reference signal is periodic configuration and the configuration type of the second reference signal is semi-static configuration.

[0389] For example, as shown in (b) of FIG. 13, the fourth indication information can be sent after the third resource configuration information. The third resource configuration information can indicate the following: the first reference signal is periodically configured, the offset T1 of the adjacent resource of the first reference signal, the non-precoding information of the first reference signal, the second reference signal is semi-statically configured, the offset T2 of the adjacent resource of the second reference signal, the transmission times of the second reference signal, and the precoding information corresponding to the second reference signal. As shown in (b) of FIG. 13, the offset of the adjacent resource of the reference signal without precoding information is T1, the offset of the adjacent resource of the reference signal with precoding information is T2, and the transmission times of the reference signal with precoding information is twice. In the scheme shown in (b) of FIG. 13, part of the reference signal configured by the third resource configuration information has been sent before the fourth indication information is sent. The reference signal after the fourth indication information among the reference signal without precoding information and the reference signal with precoding information configured by the third resource configuration information can be used for the determination of the first parameter value and the performance monitoring information. That is, the reference signal before the fourth indication information among the reference signal configured by the third resource configuration information is not used for the determination of the first parameter value and the performance monitoring information, and after the fourth indication information is received, the terminal device determines that the reference signal after the fourth indication information configured by the third resource configuration information can be used for the determination of the first parameter value and the performance monitoring information.

[0390] It should be understood that (a) and (b) of FIG. 13 are only examples and do not limit the scheme of the embodiments of the present application. For example, the third resource configuration information and the fourth indication information in FIG. 13 can be sent at other times.

[0391] In FIG. 13, the reference signal CSI-RS is only an example, and the reference signal can also be other types of reference signals.

[0392] According to the scheme of the embodiments of the present application, the same reference signal resource is used for both the determination of the value of the first parameter and the determination of the performance monitoring of the model, the configuration of the reference signal resource can be multiplexed with the value of the first parameter and the performance monitoring of the model, which is beneficial to reduce the signaling overhead required for configuring the reference signal resource, i.e., save the overhead of configuration, and also beneficial to reduce the overhead of the reference signal resource. At the same time, the terminal device can determine the pair of reference signal resources used for the determination of the value of the first parameter and the performance monitoring information according to the fourth indication information, which makes the configuration mode of the pair of reference signal resources more flexible. For example, the fourth indication information can be trigger information, and the terminal device determines that the reference signal without precoding information and the reference signal with precoding information after the fourth indication information can be used for the determination of the value of the first parameter and the performance monitoring information. For another example, the fourth indication information can be trigger information, and the reference signal without precoding information and the reference signal with precoding information configured by one or more resource configuration information after the fourth indication information can be used for the determination of the value of the first parameter and the performance monitoring information. The terminal device determines that the reference signal without precoding information and the reference signal with precoding information configured by one or more resource configuration information after the fourth indication information can be used for the determination of the value of the first parameter and the performance monitoring information.

[0393] The end of the performance monitoring of the model in the embodiments of the present application can be determined in various ways. The following takes examples 1 and 2 as examples for illustration.

[0394] Example 1 of the end mode of the performance monitoring of the model:

[0395] The network device can send indication information to the terminal device to indicate the end of performance monitoring and / or indicate that the configured reference signal stops sending, accordingly, the network device can stop sending the configured reference signal. For example, the indication information can indicate the end of performance monitoring, and the terminal device can also determine that the reference signal resource used for determining the value of the first parameter and the performance monitoring information stops sending according to the indication information. For another example, the indication information can indicate that the reference signal resource used for determining the value of the first parameter and the performance monitoring information stops sending, and the terminal device can also determine that the performance monitoring ends according to the indication information.

[0396] Optionally, the method 800 can further include the following steps (not shown in the figure):

[0397] 870, the terminal device receives the fifth indication information from the network device, the fifth indication information indicates the end of the performance monitoring of the first AI model and / or the second AI model, and / or the deactivation of the first reference signal and / or the second reference signal.

[0398] 880, the network device stops sending the first reference signal and / or the second reference signal.

[0399] For example, the terminal device can determine the above two items according to the content indicated by the fifth indication information.

[0400] For example, if the fifth indication information indicates that the performance monitoring ends, the terminal device can determine the end of the performance monitoring according to the fifth indication information, and can also determine that the network device stops sending the reference signal resource for determining the value of the first parameter and the performance monitoring information.

[0401] For another example, if the fifth indication information indicates the deactivation of the first reference signal and / or the second reference signal, the terminal device can determine that the network device stops sending the reference signal resource for determining the value of the first parameter and the performance monitoring information according to the fifth indication information, and can also determine that the performance monitoring ends.

[0402] For example, the configuration type of the first reference signal is periodic configuration, the configuration type of the second reference signal is aperiodic configuration, and all the configured resources of the second reference signal are before the fifth indication information. The fifth indication information can indicate the end of the performance monitoring, and / or the deactivation of the first reference signal. For another example, the configuration type of the first reference signal is periodic configuration, the configuration type of the second reference signal is semi-static configuration, and the fifth indication information can indicate the end of the performance monitoring, and / or the deactivation of the first reference signal and the second reference signal.

[0403] As described above, the first parameter can include parameter #2. In this case, the fifth indication information can indicate at least one of the following: the end of the calculation of the value of parameter #2, the end of the performance monitoring, and / or the deactivation of the first reference signal and / or the second reference signal.

[0404] For example, the terminal device can determine the above three items according to the content indicated by the fifth indication information.

[0405] For example, if the fifth indication information indicates the deactivation of the first reference signal and / or the second reference signal, the terminal device can determine that the network device stops sending the reference signal resource for determining the value of the first parameter and the performance monitoring information according to the fifth indication information, and can also determine that the performance monitoring ends, and can also determine that the calculation of the value of parameter #2 ends.

[0406] The end of the calculation of the value of parameter #2 can also be replaced by the end of the update of the value of parameter #2, the end of the adjustment amount calculation of parameter #1, or the end of the adjustment of the value of parameter #1.

[0407] Exemplarily, at the terminal device side, the performance monitoring ending can be the performance monitoring information reporting ending.

[0408] In the scheme of the embodiments of the present application, the network device can send indication information to the terminal device to indicate the performance monitoring ending and / or indicate the configured reference signal stopping sending, and the terminal device can determine the performance monitoring ending according to the indication information, and the network device stops sending the configured reference signal, that is, the performance monitoring ending and the reference signal stopping sending can be determined based on the same indication information, which is beneficial to reduce the signaling overhead. Further, the performance monitoring ending, the reference signal stopping sending and the adjustment ending of the value of the parameter #1 can be determined based on the same indication information, which is beneficial to reduce the signaling overhead.

[0409] In addition, for the scheme 2 in the foregoing, the fifth indication information can be used to determine the performance monitoring ending of the first AI model and / or the second AI model, and / or the calculation ending of the value of the parameter #2.

[0410] Exemplarily, the terminal device can determine the above two according to the fifth indication information.

[0411] For example, the fifth indication information indicates the performance monitoring ending, and the terminal device can determine the performance monitoring ending and / or determine not to calculate the value of the parameter #2 according to the fifth indication information.

[0412] For another example, the fifth indication information indicates the calculation ending of the value of the parameter #2, and the terminal device can determine not to calculate the value of the parameter #2 and / or determine the performance monitoring ending according to the fifth indication information.

[0413] For another example, the fifth indication information indicates the calculation ending of the value of the parameter #2 and the performance monitoring ending, and the terminal device can determine not to calculate the value of the parameter #2 and / or determine the performance monitoring ending according to the fifth indication information.

[0414] For another example, the fifth indication information can be used as trigger information, and the reference signal resources configured after the fifth indication information are not used for determining the value of the parameter #2 and the performance monitoring information. The terminal device can determine not to calculate the value of the parameter #2 and / or determine the performance monitoring ending according to the fifth indication information.

[0415] The network device can also not stop sending the reference signal resources, but the reference signal is no longer used for determining the value of the parameter #2 and the performance monitoring information. For example, the reference signal resources configured after the fourth indication information can be used for determining the value of the first parameter and the performance monitoring information, and after receiving the fifth indication information, the terminal device can determine that the configured reference signal resources are no longer used for determining the value of the parameter #2 and the performance monitoring information.

[0416] Example 2 of the performance monitoring ending mode of the model:

[0417] Optionally, the time-domain resource for transmitting the first reference signal and the time-domain resource for transmitting the second reference signal are within an effective time period.

[0418] In other words, the reception time of the first reference signal and the reception time of the second reference signal are within the effective time period. Alternatively, the transmission time of the first reference signal and the transmission time of the second reference signal are within the effective time period.

[0419] In other words, the reference signal without precoding information and the reference signal with precoding information within the effective time period can be used to determine the value of the first parameter and the performance monitoring information, and the reference signal outside the effective time period is not used to determine the value of the first parameter and the performance monitoring information.

[0420] Further, the method 800 can further include: at the end time of the effective time period or after the end time, the performance monitoring ends.

[0421] For example, the terminal device can end the performance monitoring of the first AI model and / or the second AI model at the end time of the effective time period.

[0422] The end time of the effective time period can also be replaced by an invalid time unit.

[0423] The "time" in the embodiments of the present application can be understood as any one or more of a time slot, a subframe, a frame, and an OFDM symbol. For example, the time corresponding to A can be the time slot, the subframe, the frame, or the OFDM symbol in which A is located, or the first time slot, the subframe, the frame, or the OFDM symbol in which A is located, or the last time slot, the subframe, the frame, or the OFDM symbol in which A is located.

[0424] Exemplarily, the effective time period can be predefined or indicated by the network device.

[0425] Further, the method 800 can further include: at the end time of the effective time period or after the end time, the network device stops transmitting the first reference signal and / or the second reference signal.

[0426] Further, the method 800 can further include: the terminal device receives sixth indication information from the network device, the sixth indication information indicating the deactivation of the first reference signal and / or the second reference signal.

[0427] For example, the effective time period can be predefined, in which case the network device can send the sixth indication information to the terminal device to indicate the deactivation of the first reference signal and / or the second reference signal.

[0428] For example, the valid time period can be indicated by the network device, in which case the network device can send sixth indication information to the terminal device. Alternatively, the network device can also not send the sixth indication information.

[0429] As described above, the first parameter can include parameter #2. In this case, the calculation of the value of parameter #2 can also end at or after the end time of the valid time period.

[0430] The determination of the valid time period is described below.

[0431] Optionally, any one or more of the length of the valid time period, the start time of the valid time period, or the end time of the valid time period can be predefined, or obtained through indication information from the network device.

[0432] In the case where the valid time period is determined according to the length of the valid time period, the timer of the valid time period can be on the terminal device, i.e. counted by the terminal device, or on the network device, i.e. counted by the network device.

[0433] The determination of the valid time period is described below.

[0434] For example, the method 800 can also include that the terminal device receives seventh indication information from the network device, the seventh indication information indicating the length of the valid time period. The start time of the valid time period can be any one of the following: the calculation time of the first adjustment amount, the sending time of the first reference signal, the receiving time of the first reference signal, the sending time of the second reference signal, the receiving time of the second reference signal, the sending time of the seventh indication information, the receiving time of the seventh indication information, the time indicated by the seventh indication information, the sending time of other indication information, the receiving time of other indication information, or the time indicated by other indication information.

[0435] For example, the start time of the valid time period can be the sending time of the seventh indication information or the receiving time of the seventh indication information, and the seventh indication information can also be the fourth indication information. For example, the start time of the valid time period can be the sending time of other indication information or the receiving time of other indication information, and the other indication information can also be the fourth indication information.

[0436] For example, the timer can be on the terminal device, and the start time of the valid time period can be any one of the following: the calculation time of the first adjustment amount, the receiving time of the first reference signal, the receiving time of the second reference signal, the receiving time of the seventh indication information, the time indicated by the seventh indication information, the receiving time of other indication information, or the time indicated by other indication information.

[0437] For another example, the timer can be on the network device, and the start time of the valid time period can be any one of the following: the sending time of the first reference signal, the sending time of the second reference signal, the sending time of the seventh indication information, the time indicated by the seventh indication information, the sending time of other indication information, or the time indicated by other indication information.

[0438] For an example, the length of the valid time period can be predefined. The start time of the valid time period can be any one of the following: the sending time of the first reference signal, the receiving time of the first reference signal, the sending time of the second reference signal, the receiving time of the second reference signal, the sending time of the ninth indication information from the network device, the receiving time of the ninth indication information, or the time indicated by the ninth indication information.

[0439] For an example, the start time of the valid time period can be the sending time of the ninth indication information or the receiving time of the ninth indication information, and the ninth indication information can also be the fourth indication information.

[0440] For an example, the timer can be on the terminal device, and the start time of the valid time period can be any one of the following: the receiving time of the first reference signal, the receiving time of the second reference signal, the receiving time of the ninth indication information, or the time indicated by the ninth indication information.

[0441] For another example, the timer can be on the network device, and the start time of the valid time period can be any one of the following: the sending time of the first reference signal, the sending time of the second reference signal, the sending time of the ninth indication information, or the time indicated by the ninth indication information.

[0442] For an example, the method 800 can further include: the terminal device receiving eighth indication information from the network device, the eighth indication information indicating the end time of the valid time period. The start time of the valid time period can be any one of the following: the sending time of the first reference signal, the receiving time of the first reference signal, the sending time of the second reference signal, or the receiving time of the second reference signal, the sending time of the eighth indication information, the receiving time of the eighth indication information, the time indicated by the eighth indication information, the sending time of other indication information, the receiving time of other indication information, or the time indicated by other indication information.

[0443] For an example, the start time of the valid time period can be the sending time of the eighth indication information or the receiving time of the eighth indication information, and the eighth indication information can also be the fourth indication information.

[0444] For an example, the end time of the valid time period can be indicated by the eighth indication information. The length of the valid time period can be predefined or indicated by the seventh indication information.

[0445] According to the scheme of the embodiments of the present application, the effective period of the first reference signal and the second reference signal can be set, and the reference signal resource in the effective period can be used for the value of the first parameter and the determination of the performance monitoring information, which is more flexible. In addition, outside the effective period, the network device can stop sending the first reference signal and the first reference signal, and the performance monitoring of the model ends, which is beneficial to reduce the signaling overhead.

The method 1500 shown in FIG. 14 can be regarded as a specific implementation of the method 800.

[0447] FIG. 15 is a schematic diagram of a time line flow of the method 1500 shown in FIG. 14.

[0448] As shown in FIG. 14, the method 1500 can include the following steps.

[0449] 1501, the network device sends third resource configuration information to the terminal device. The third resource configuration information indicates the resource configuration of the CSI-RS resource pair. The CSI-RS resource pair includes a CSI-RS without precoding information (an example of the first reference signal) and a CSI-RS with precoding information (an example of the second reference signal). The third resource configuration information indicates that the configured CSI-RS resource pair is used for the value of the adjustment amount of CQI and the determination of the performance monitoring information of the first AI model and / or the second AI model. Or, the third resource configuration information indicates that the configured CSI-RS resource pair is used for the adjustment of CQI and the performance monitoring of the first AI model and / or the second AI model.

[0450] The third resource configuration information is only an example, and the CSI-RS resource pair can also be configured by multiple resource configuration information, for example, the first resource configuration information and the second resource configuration information in the method 800.

[0451] As shown in FIG. 15, the third resource configuration information can be carried in radio resource control (RRC) and activated by MAC CE or DCI, or carried in MAC CE, or carried in MAC CE and activated by DCI, or carried in RRC. The offset of the adjacent resource of the CSI-RS with non-precoding information configured by the third resource configuration information is T1.

[0460] The terminal device can calculate a value of an adjustment amount of CQI according to CQI1 and CQI2. The value of the adjustment amount of CQI can be used to adjust other values of CQI.

[0461] For example, the value of the adjustment amount of the CQI can be used to adjust the value of the CQI determined based on the measurement result of the reference signal based on the other non-precoding information. That is, the terminal device can adjust other values of the CQI according to CQI1 and CQI2. The specific adjustment manner can refer to the method 800, which will not be described here.

[0471] For example, as shown in FIG. 14 and FIG. 15, the fifth indication information indicates that the performance monitoring is ended, and the network device stops sending the CSI-RS configured by the third resource configuration information. The fifth indication information can also indicate other contents, which can be referred to the method 800, which will not be described here.

The offset of the adjacent resources of the CSI-RS with precoded information is T2. Network devices can send CSI-RS with precoded information according to the second resource configuration information.

[0486] The first and second resource configuration information in Method 1700 are merely examples. CSI-RS resource pairs can also be configured by a single resource configuration information, such as the third resource configuration information in Method 800. The positions of the fourth indication information, the first resource configuration information, and the second resource configuration information can also be other locations.

[0525] As shown in FIG. 19, after S1, the performance monitoring ends, and the network device stops sending the CSI-RS configured by the third resource configuration information.

[0526] FIG. 20 shows a schematic flowchart of a method of communication according to an embodiment of the present application. The method 2100 shown in FIG. 20 can be regarded as a specific implementation of the method 800. The specific description can refer to the method 800, and part of the description is appropriately omitted when describing the method 2100. In the method 2100, the first AI model is deployed on the OTT on the terminal device side, and the second AI model is deployed on the intelligent network element on the network device side.
