Wireless communication method, terminal and network side device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese Patent Application No. 202411374509.2, filed on September 29, 2024, and titled "Wireless communication method, terminal and network side device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application belongs to the field of communication technology, and specifically relates to a wireless communication method, a terminal and a network side device. BACKGROUND

[0004] In a Multiple-Input Multiple-Output (MIMO) communication system, the acquisition of channel information is crucial. A terminal needs to acquire channel information, such as Channel State Information (CSI), by measuring reference signals, and report the acquired channel information to a network side device.

[0005] Since the channel information acquired by measuring the reference signals has timeliness, it may not reflect the current latest channel situation. In the related art, the time-frequency resources occupied by the reference signals increase with the increase of the port number of the network side device. Taking Channel State Information Reference Signal (CSI-RS) as an example, the CSI-RS occupies the same number of resource elements (REs) as the port number of the CSI-RS in one resource block (RB). In the future, with the development of antenna array technology and the use of new frequency bands, the port number of the network side device will gradually increase, for example, from 32 ports to 512 ports or even higher, at which time the resource overhead occupied by sending reference signals will be unacceptable.

[0006] In order to reduce the resources occupied by the reference signals used for channel estimation, an Artificial Intelligence (AI) model can estimate complete channel information based on incomplete channel information. For example, the AI model can estimate the channel information of all ports based on the channel information of a part of the ports. The channel information of the part of the ports can be the channel information obtained by measuring the reference signals sent by the network side device.

[0007] However, although complete channel information can be obtained on the basis of reducing the resources occupied by the reference signal for channel estimation through the AI model, how to improve the estimation performance of the channel information on the basis of reducing the resource overhead of the reference signal is still a technical problem urgently to be solved in the field.

It should be noted that in the embodiments of the present application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0102] In order to better understand the embodiments of the present application, the related technologies of the present application are described.

[0103] (1) Artificial Intelligence (AI).

[0104] AI has been widely applied in various fields. Integrating artificial intelligence into wireless communication networks significantly improves technical indicators such as throughput, latency, and user capacity, which is an important task for future wireless communication networks. AI modules have various implementation methods, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. The present application takes a neural network as an example for illustration, but the specific type of AI module is not limited.

[0105] FIG. 2 is an example of a structure of a neural network according to an embodiment of the present application.

[0106] As shown in FIG. 2, the structure of the neural network includes an input layer, a hidden layer (also referred to as a hidden layer), and an output layer. The input of the input layer is X1~X n , and the output of the output layer is Y. It should be understood that the present application takes a neural network as an example for illustration, but the specific type of AI module is not limited.

[0107] FIG. 3 is an example of a structure of a neuron according to an embodiment of the present application.

[0108] As shown in FIG. 3, a neural network is composed of neurons. The output of a neuron is z, z = a1w1+…+a k w k +…+a K w K , where a1~a K are inputs, w1~w K are weights (multiplicative coefficients), b is a bias (additive coefficient), and σ(.) is an activation function. The activation function includes a Sigmoid function, a tanh function, a Rectified Linear Unit (ReLU) (also known as a linear rectifier function), and the like.

[0109] The parameters of a neural network are optimized by an optimization algorithm. An optimization algorithm is a type of algorithm that can minimize or maximize an objective function (sometimes also called a loss function). The objective function is often a mathematical combination of model parameters and data. For example, given data X and its corresponding label Y, a neural network model f(.) is constructed. After the model is obtained, the estimated output f(x) can be obtained according to the input x, and the difference between the estimated value and the true value (f(x)-Y) can be calculated, which is the loss function. The purpose is to find appropriate W, b to minimize the value of the above loss function. The smaller the loss value, the closer the AI model is to the true situation.

[0110] Optimization algorithms are usually based on the error Back Propagation (BP) algorithm. The basic idea of the BP algorithm is that the learning process consists of two processes of forward propagation of signals and backward propagation of errors. When forward propagating, the input sample is transmitted from the input layer, processed layer by layer through each hidden layer, and then transmitted to the output layer. If the actual output of the output layer does not match the expected output, the backward propagation of errors is entered. Error back propagation is to transmit the output error to the input layer through the hidden layer in a certain form, and allocate the error to all units of each layer, so as to obtain the error signal of each unit, which is used as the basis for correcting the weights of each unit. The process of adjusting the weights of each layer through forward propagation of signals and backward propagation of errors is repeated. The process of continuously adjusting the weights is the learning and training process of the network. This process continues until the error of the network output is reduced to an acceptable level, or until the pre-set learning times are reached.

[0111] The optimization algorithm can be specifically Gradient Descent, Stochastic Gradient Descent (SGD), mini-batch gradient descent, Momentum, Stochastic Gradient Descent with Momentum (such as Nesterov), Adaptive Gradient Descent (Adagrad), Adadelta, root mean square prop (RMSprop), Adaptive Moment Estimation (Adam), etc. When error back propagation, these optimization algorithms can obtain the error / loss from the loss function, calculate the derivative / partial derivative of the current neuron, add the learning rate, the previous gradient / derivative / partial derivative, obtain the gradient, and pass the gradient to the previous layer.

[0112] (2) AI-based low-overhead pilot channel estimation method.

[0113] In a Multiple-Input Multiple-Output (MIMO) communication system, it is crucial to obtain channel information. In order to estimate the downlink channel, the base station needs to send a reference signal, such as a Channel State Information Reference Signal (CSI-RS). In related technologies, the time-frequency resources occupied by the reference signal increase with the increase of the number of base station ports. Taking the CSI-RS as an example, the CSI-RS occupies the same number of resource elements (REs) as the number of ports of the CSI-RS in one resource block (RB). In the future, with the development of antenna array technology and the use of new frequency bands, the number of base station ports will gradually increase, for example, from 32 ports to 512 ports or even higher, at which time the resources occupied by the transmission of the reference signal will be unacceptable.

[0114] To reduce the resource occupied by the reference signal for channel estimation, a single-end model can use a low-overhead reference signal (e.g., only some ports transmit the reference signal) to obtain complete channel information. A simple example is shown in FIG. 4, where each block represents a port, and the gray blocks represent the channel information of the port that has been obtained, e.g., by transmitting a reference signal. Due to the limited overhead of the reference signal, the channel information of some ports has not been obtained, as shown by the white blocks. As shown in FIG. 4, the AI model can ultimately estimate the complete channel information based on incomplete channel information.

[0115] It should be noted that the final channel inference performance may be different when different ports are used to transmit the reference signal. On the one hand, the channel responses at different positions on the antenna array are different, that is, the channel responses on some ports are relatively strong, and the signal-to-noise ratio is high, while the channel responses on some other positions are relatively weak, and the signal-to-noise ratio is low. Therefore, in the case of selecting a small number of ports, the channel responses of the selected ports need to be strong according to the channel information, which helps to improve the channel estimation performance, and for different terminals, the selected ports may also be different due to the different received channels. On the other hand, the inference ability of the single-end neural network of the terminal may be different, so even if facing similar channel information, it may also lead to different ports selected by different terminals.

[0116] Further, a random sampling network can be introduced in the single-end neural model to learn appropriate ports to transmit the reference signal. However, it should be noted that, in terms of the downlink reference signal, the channel estimation process is at the terminal side, that is, the training (including learning appropriate ports for transmitting the reference signal) and inference of the model are both at the terminal, while the transmission of the reference signal is at the base station side. Therefore, the interaction process between the base station and the terminal is needed to determine the final ports used to transmit the downlink reference signal.

[0117] For a single-end neural model for estimating full-port channel based on low-overhead pilot at a terminal side, the application provides a communication process between a network side device and a terminal, so that the terminal can determine at least one first port through at least one first reference signal received on at least one first resource and report the at least one first port to the network side device, so that the network side device configures a port of at least one second reference signal for the terminal according to the at least one first port, and transmits the at least one second reference signal to the terminal using the port of the at least one second reference signal, so that the terminal can estimate channel information of all ports based on channel information of the at least one second reference signal. Specifically, the terminal can determine at least one first port that can guarantee the estimation performance of channel information according to the configuration of the network side device, and report the at least one first port to the network side device, so that in the estimation process of channel information, not only the pilot overhead (the number of transmission ports) can be reduced, but also the estimation performance of channel information can be guaranteed. Further, since the port sets reported by different terminals can be different, for terminals with different reported port sets, when the network side device configures at least one second resource for transmitting the at least one second reference signal, the network side device can configure the resource type of different second resources in the at least one second resource through different configuration information, for example, one periodic and one aperiodic second resource can be configured for each terminal, multiple terminals can share the same second resource, and reference signals are transmitted on the aperiodic second resource according to the measurement requirements of each terminal. In this way, it is not necessary to transmit reference signals corresponding to different port sets for each terminal, so that the utilization efficiency of reference signal resources can be improved, and the reference signal overhead can be reduced.

[0118] The wireless communication method provided by the embodiments of the application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.

[0119] It should be noted that the reference signal (for example, the first reference signal or the second reference signal) involved in the present application can be a reference signal used in a communication system, such as a channel state information-reference signal (CSI-RS), a demodulation reference signal (DMRS), a synchronization signal block (SSB), etc., and the present application does not make a limitation in this regard. Different configuration information can be indicated by the same signaling, and one configuration information can be indicated by multiple signaling, and the present application does not make a limitation in this regard. The identification number involved in the present application can also be an index or a serial number, and the present application does not make a limitation in this regard. The index or the serial number in the present application can start from 0, can start from 1, or can start from another number, and the present application does not make a limitation in this regard.

[0120] In addition, the port set involved in the present application can also be referred to as a basic set, a port basic set, a basic port set, a basic combination, a port basic combination, a basic port combination, and other terms with similar meanings, and the present application does not make a specific limitation in this regard. One or more port sets can be used to form a port pattern, and a port pattern includes at least one port. It can be understood that all the ports in the one or more port sets form a port pattern. The terminal can determine the transmission port of the reference signal in units of the port pattern, and the port pattern can also be referred to as a transmission port pattern, a reference signal transmission port pattern, and other terms with similar meanings, and the present application does not make a specific limitation in this regard. It should be noted that without introducing the port set, one or more ports can be used to form a port pattern, and the present application does not make a specific limitation in this regard.

[0121] In addition, the port involved in the present application can also be referred to as an antenna port, a dual-polarized antenna port or a dual-polarized antenna port pair, and can include a transmitting port and a receiving port. Among them, the transmitting port can be understood as a virtual antenna identified by the receiving device. Alternatively, the port can refer to a transmitting antenna port. For example, the reference signal sent by each transmitting antenna port can be an unprecoded reference signal. Among them, the transmitting antenna port can refer to an actual independent transmitting unit (transceiver unit, TxRU). Alternatively, the port can also refer to a port after beamforming. For example, the reference signal sent by each port can be a precoded reference signal obtained by precoding the reference signal based on an angle vector. It can be understood that if the reference signal is beamformed, the number of ports can refer to the number of precoded reference signals. The number of ports of the precoded reference signal can be less than the number of transmitting antenna ports. The reference signal of each port can be transmitted through one or more frequency domain units. The receiving port can be understood as the receiving antenna of the receiving device. For example, in downlink transmission, the receiving port can refer to the receiving antenna of the terminal device.

[0124] S201, a terminal receives first configuration information from a network side device, wherein the first configuration information is used to indicate at least one first resource.

[0125] Exemplarily, the first configuration information is related configuration of at least one first reference signal for data collection / model training.

[0126] S202, the terminal receives at least one first reference signal from the network side device on the at least one first resource.

[0127] S203, the terminal determines at least one first port based on the at least one first reference signal.

[0128] Exemplarily, the terminal measures the at least one first reference signal to obtain at least one channel information, and obtains the at least one first port based on the at least one channel information in a machine learning manner. For example, the terminal can determine the at least one first port satisfying the following conditions through a machine learning model, such as a random sampling network: the channel information estimation performance of an AI model satisfies a threshold value for determining the at least one first port, a port set composed of the at least one first port satisfies a network-side device configuration requirement (for example, a rule configured by the network-side device) and has a minimum number of ports. Optionally, the at least one channel information is used to determine the performance of the AI model, and the threshold value can be a parameter configured by the network-side device or agreed by a protocol.

[0129] Exemplarily, the terminal can determine the at least one first port based on the at least one first reference signal, the at least one first port includes at least one port pattern, or in other words, the at least one first port can be divided into at least one first port pattern, and it should be understood that the at least one first port can also constitute a first port pattern. In this case, after obtaining the at least one channel information, the terminal can obtain the at least one port pattern based on the at least one channel information in a machine learning manner. For example, the terminal can determine the at least one port pattern satisfying the following conditions through a machine learning model, such as a random sampling network: the channel information estimation performance of an AI model satisfies a threshold value for determining the port pattern, the port pattern satisfies a network-side device configuration requirement (for example, a rule configured by the network-side device) and has a minimum number of ports. Optionally, the at least one channel information is used to determine the performance of the AI model, and the threshold value can be a parameter configured by the network-side device or agreed by a protocol.

[0130] It should be noted that if the at least one first port is divided into at least one port pattern, the specific division manner or division form is not limited in the present application. For example, different port patterns in the at least one port pattern can include the same ports or at least partially different ports; in other words, the ports included in different port patterns in the at least one port pattern can overlap or not overlap. For another example, the number of ports included in different port patterns in the at least one port pattern can be the same or different. For another example, there can be only one port pattern, and the port pattern is composed of the at least one first port. The present application does not make specific limitation thereon. Optionally, the terminal can report the division manner or division form of the at least one first port.

[0131] The AI model in the embodiments of the present application can also be referred to as an AI unit, an ML (machine learning) model, an ML unit, an AI structure, an AI feature, a machine learning model, a neural network, a neural network function, a neural network function, etc. Alternatively, the AI model can refer to a processing unit capable of implementing a specific algorithm, formula, processing flow, capability, etc. related to AI, or the AI model can be a processing method, algorithm, function, module or unit for a specific data set, or the AI model can be a processing method, algorithm, function, module or unit running on AI / ML related hardware such as a GPU (Graphics Processing Unit), NPU (Neural Processing Unit), TPU (Tensor Processing Unit), ASIC (Application Specific Integrated Circuit), etc. The present application does not make specific limitations on this. The specific data set can include the input and / or output of the AI unit / AI model.

[0132] The identification number of the AI unit / AI model can be a model identification number, an AI model identification, an AI structure identification, an AI algorithm identification, or an identification of a specific data set associated with the AI unit / AI model, or an identification of a specific scene, environment, channel feature, device related to AI / ML, or an identification of a function, feature, capability or module related to AI / ML. The present application does not make specific limitations on this.

[0133] In S204, the terminal reports first reporting information to the network side device, and the first reporting information is used to indicate the at least one first port.

[0134] For example, the at least one first port is used by the network side device to determine the transmission port of at least one second reference signal, or in other words, the at least one first port can be a port selected by the terminal for the network side device to transmit at least one second reference signal. For example, the at least one first port is {port #1, port #3, port #5}, indicating that the ports used by the network side device to transmit at least one second reference signal include port #1, port #3 and port #5. Optionally, the channel information of the at least one second reference signal is used to estimate the channel information of all ports. The channel information of the at least one second reference signal refers to the channel information measured for the at least one second reference signal.

[0135] Exemplarily, the at least one first port can be used to form at least one port pattern in which the network-side device transmits the reference signal, and the first reporting information is used to indicate the at least one port pattern. Alternatively, the at least one first port can be used to form one port pattern, i.e., the at least one first port is used to form the port pattern in which the network-side device transmits the reference signal, and the first reporting information is used to indicate the port pattern in which the network-side device transmits the reference signal. If the at least one first port is divided into at least one port pattern or the first reporting information is used to indicate the at least one port pattern, the at least one port pattern is used by the network-side device to determine a transmission port pattern of at least one second reference signal, or in other words, each port pattern in the at least one port pattern is a port pattern selected by the terminal for the network-side device to transmit the at least one second reference signal. It should be understood that the transmission port pattern of the reference signal or the port pattern in which the reference signal is transmitted can be understood as one or more ports used by the reference signal for transmission.

[0136] In the embodiments of the present application, the terminal can determine at least one first port based on the received at least one first reference signal and report the at least one first port to the network-side device, which helps the network-side device to select a port for transmitting a reference signal that can ensure the estimation performance of channel information based on the at least one first port, and further helps to ensure the estimation performance of channel information on the basis of reducing the resource overhead of the reference signal.

[0137] In some embodiments, the method 200 further includes:

[0138] The terminal receives second configuration information, and the second configuration information is used to indicate at least one second resource and at least one of the following:

[0139] a port of at least one second reference signal;

[0140] a mapping relationship between the port of the at least one second reference signal and the port of the at least one first reference signal;

[0141] The terminal receives the at least one second reference signal on the at least one second resource.

[0142] Exemplarily, when the second configuration information is used to indicate the at least one second resource and the port of the at least one second reference signal, the terminal receives the at least one second reference signal from the network-side device on the at least one second resource and determines the port used for transmitting the second reference signal according to the second configuration information. Similarly, when the second configuration information is used to indicate the at least one second resource and the mapping relationship, the terminal receives the at least one second reference signal from the network-side device on the at least one second resource and determines the port used for transmitting the second reference signal according to the second configuration information.

[0143] Exemplarily, the at least one second reference signal is used for channel measurement or estimation of channel information of all ports. For example, the terminal measures the at least one second reference signal to obtain channel information of the at least one second reference signal, estimates channel information of all ports based on the channel information of the at least one second reference signal to obtain estimated channel information, and reports the estimated channel information to the network-side device.

[0144] In some embodiments, the resource types of different second resources in the at least one second resource are indicated by different configuration information.

[0145] Exemplarily, different resource types in the at least one second resource are indicated by different configuration information in the second configuration information. The resource types can include periodic resources, aperiodic resources, or semi-persistent resources.

[0146] Since the reported ports or port patterns of different terminals can be different, when the network-side device configures the at least one second resource used for transmitting the at least one second reference signal for the terminals with different reported ports or port patterns, the resource types of different second resources in the at least one second resource are configured by different configuration information in this embodiment. For example, one periodic and one aperiodic second resource can be configured for each terminal, and multiple terminals can share the same second resource. Then, the reference signal is transmitted on the aperiodic second resource according to the measurement requirements of each terminal. In this way, it is not necessary to configure the reference signal corresponding to different port sets for each terminal, so that the utilization efficiency of the reference signal resource can be improved, and the reference signal overhead can be reduced.

[0147] In some embodiments, the second configuration information is used to indicate a first bit map, and each bit in the first bit map indicates whether a port or a port of the first reference signal is a port of the second reference signal. For example, each bit indicates whether a port of the network-side device is a port of the second reference signal, thereby indicating the port of the second reference signal.

[0148] Exemplarily, a number of bits of the first bitmap is equal to a number of ports of the network-side device, and each bit in the first bitmap indicates whether a port corresponding to the bit is a port of the second reference signal, thereby indicating the ports of the second reference signal. For example, a first value of a first bit in the first bitmap indicates that a port corresponding to the first bit is a port of the second reference signal, and a second value of the first bit indicates that the port corresponding to the first bit is not a port of the second reference signal, the first value being 1 and the second value being 0, or the first value being 0 and the second value being 1. Optionally, the ports corresponding to the bits are arranged in an order of a first dimension, a second dimension, and a polarization direction, or in an order of the second dimension, the first dimension, and the polarization direction.

[0149] Exemplarily, a number of bits of the first bitmap is equal to a number of ports of the at least one first reference signal, and each bit in the first bitmap indicates whether a port of a first reference signal corresponding to the bit is a port of the second reference signal, thereby indicating a mapping relationship between the ports of the second reference signal and the ports of the first reference signal. For example, a first value of a first bit in the first bitmap indicates that a port of a first reference signal corresponding to the first bit is a port of the second reference signal, and a second value of the first bit indicates that the port of the first reference signal corresponding to the first bit is not a port of the second reference signal, the first value being 1 and the second value being 0, or the first value being 0 and the second value being 1.

[0150] In some embodiments, the second configuration information is further used to indicate at least one of the following:

[0151] a first identification number associated with the at least one first resource;

[0152] a second identification number associated with a first resource group, the first resource group being associated with part or all of the at least one first resource, for example, the first resource group can be a resource group obtained by dividing the at least one first resource;

[0153] a third identification number associated with third configuration information, the third configuration information being used to indicate a reporting configuration of the first reporting information;

[0154] an identification number of an AI model.

[0155] In some embodiments, the first configuration information is further used to indicate at least one of the following:

[0156] a topology of the port set associated with the at least one first resource;

[0157] a first identification number associated with the at least one first resource;

[0158] a second identification number associated with a first resource group, the first resource group being associated with part or all of the at least one first resource, for example, the first resource group can be a resource group obtained by dividing the at least one first resource.

[0159] In some embodiments, if the at least one first port is divided into at least one port pattern, the first reporting information is used to indicate the at least one port pattern, and a first port pattern in the at least one port pattern is indicated by at least one of the following:

[0160] a first candidate port set in the at least one candidate port set, the first port pattern including all ports in the first candidate port set;

[0161] a second bit map, each bit in the second bit map indicating whether a port is a port in the first port pattern;

[0162] at least one first port set, the first port pattern including part or all of the ports in the at least one first port set.

[0163] For example, the first reporting information is specifically used to indicate at least one first candidate port set, any one of the at least one first candidate port set can be used as the first port pattern, that is, the first port pattern can include all ports in any one of the at least one first candidate port set.

[0164] In other words, the network side device configures the terminal with at least one candidate port set, and the terminal determines at least one candidate port set (i.e., the at least one first candidate port set) to report to the network side device. Wherein each first candidate port set can be used as a port pattern for the network side device to send at least one second reference signal, and the at least one second reference signal is used for channel measurement or estimation of complete port channel information.

[0165] Exemplarily, the first reporting information is used for indicating at least one bitmap, any bitmap in the at least one bitmap indicates at least one port which can be used to form the first port pattern, i.e., the first port pattern can include at least one port indicated by any bitmap in the at least one bitmap. Each bit in the second bitmap can indicate whether a port is included in the first port pattern, for example, when a first bit in the first bitmap has a first value, it indicates that a port corresponding to the first bit belongs to ports included in the first port pattern, when the first bit has a second value, it indicates that the port corresponding to the first bit does not belong to the ports included in the first port pattern, the first value is 1 and the second value is 0, or the first value is 0 and the second value is 1. Optionally, the ports corresponding to each bit are arranged in the order of first dimension, second dimension, and polarization direction, or in the order of second dimension, first dimension, and polarization direction.

[0166] Exemplarily, the first reporting information is specifically used for indicating at least one port set group, any port set group in the at least one port set group includes at least one first port set, and part or all ports in all first port sets in the any port set group can be used as the first port pattern, i.e., the first port pattern can include part or all ports in all first port sets in the any port set group. Optionally, all ports in each first port set can be indicated by protocol or by a network side device to belong to the first port pattern, and for example, which ports in each first port set belong to the first port pattern can be indicated by protocol or by the network side device. For example, one or more ports in each first port set can be indicated by protocol or by the network side device to belong to the first port pattern, i.e., for each first port set in a port set group, one or more ports belonging to a port pattern can be indicated by protocol or by the network side device.

[0167] In some embodiments, the first reporting information is further used for indicating at least one of the following:

[0168] a first identification number associated with the at least one first resource;

[0169] a second identification number associated with a first resource group, the first resource group is associated with part or all resources in the at least one first resource, for example, the first resource group can be a resource group obtained by dividing the at least one first resource;

[0170] a third identifier associated with third configuration information, the third configuration information being used to indicate a reporting configuration of the first reporting information;

[0171] an identifier of the AI model.

[0172] In some embodiments, before the S202, the method 200 further includes:

[0173] receiving, by the terminal, the third configuration information;

[0174] wherein the third configuration information is used to indicate at least one of the following:

[0175] the at least one candidate port set;

[0176] a second port set, ports in the second port set being the first port.

[0177] Exemplarily, the candidate port set can also be referred to as a set of selectable or usable ports.

[0178] Exemplarily, the second port set can also be referred to as a set of ports that must be selected or used. The second port set can be empty or non-empty.

[0179] Exemplarily, when the third configuration information is used to indicate the at least one candidate port set, all ports in a certain candidate port set (i.e., the first candidate port set) selected by the terminal from the at least one candidate port set are used as a port pattern or the at least one first port. All ports in a candidate port set can be used as a port pattern. For example, if the third configuration information is used to indicate the at least one candidate port set, the first reporting information is used to indicate at least one first candidate port set, and all ports in any one of the at least one first candidate port set can be used to form a port pattern, such as the first port pattern mentioned above. That is, the first port pattern can include all ports in any one of the at least one first candidate port set.

[0180] Exemplarily, when the third configuration information is used to indicate the second port set, the terminal selects part or all of the ports in the at least one first port set as a port pattern or the at least one first port on the basis of the second port set. When the first reporting information is used to indicate at least one port pattern, the first reporting information is used to indicate at least one port set group, wherein all of the part or all of the ports in the first port set and all of the ports in the second port set in any one port set group can be used to form a port pattern, for example, the first port pattern mentioned above, that is, the first port pattern can include all of the part or all of the ports in the first port set in any one port set group and all of the ports in the second port set.

[0181] For example, for the first port pattern, when the first reporting information is used to indicate a first candidate port set, the first port pattern includes all of the ports in the first candidate port set. Similarly, when the first reporting information is used to indicate at least one first port set, the first port pattern includes all of the ports in the second port set and part or all of the ports in the at least one first port set. The second port set can be empty or non-empty.

[0182] In some embodiments, the third configuration information is further used to indicate at least one of the following:

[0183] A threshold value used to determine the at least one first port;

[0184] A third identification number associated with the third configuration information;

[0185] An uplink resource used by the first reporting information.

[0186] In some embodiments, the first identification number includes at least one of the following: a resource identification number, a dataset identification number (dataset ID), an associated identification number (associated ID), a beam identification number (beam ID), a cell identification number (cell ID), and an identification number of an AI model; or the second identification number includes at least one of the following: a resource group identification number, a dataset identification number, an associated identification number, a beam identification number, a cell identification number, and an identification number of an AI model.

[0187] In some embodiments, if the at least one first port is divided into at least one port pattern, a first port pattern in the at least one port pattern satisfies at least one of the following:

[0188] A distance between ports in the first port pattern is greater than or equal to a first threshold;

[0189] a first number of ports in the first port pattern meets a first requirement;

[0190] a second number of ports in the first port pattern other than a second port set meets a second requirement, the second port set being a port set indicated by third configuration information, the third configuration information being used for indicating reporting configuration of the first reporting information, ports in the second port set being the first ports;

[0191] the at least one first port is uniformly distributed in at least one dimension (e.g., a first dimension or a second dimension).

[0192] Exemplarily, the first number is greater than or equal to the second number. For example, when the second port set is empty, the first number is equal to the second number. For another example, when the second port set is non-empty, the first number is greater than the second number.

[0193] In some embodiments, the first number of ports in the first port pattern meets the first requirement comprises at least one of:

[0194] the first number is within a first value range;

[0195] the first number is less than or equal to a first maximum value.

[0196] Exemplarily, the first value range can be agreed by a protocol or configured by a network-side device. The first value range can include one or more values, for example, the first value range can be 4, 8, 12, 24, 32. The first value range can be a continuous value range, for example, the first value range can be [4, 32]. The first maximum value can be agreed by a protocol or configured by a network-side device. The first maximum value can be an even number. For example, the first maximum value can be a multiple of 2 or a multiple of 4.

[0197] In some embodiments, the second number of ports in the first port pattern other than the second port set meets the second requirement comprises at least one of:

[0198] the second number is within a second value range;

[0199] the second number is less than or equal to a second maximum value.

[0200] Exemplarily, the second value range can be agreed by a protocol or configured by a network side device. The second value range can include one or more values, for example, the second value range can be 2, 4, 6, 8, 10. The second value range can be a continuous value range, for example, the second value range can be [2, 10]. The second maximum value can be agreed by a protocol or configured by a network side device. The second maximum value can be an even number. For example, the second maximum value can be a multiple of 2 or a multiple of 4.

[0201] In some embodiments, before the S201, the method 200 further includes:

[0202] The terminal reports capability information of the terminal, and the capability information is used to indicate at least one of the following:

[0203] an indication of whether the terminal supports a capability of estimating channel information of all ports using channel information of part of the ports;

[0204] an indication of whether the terminal supports multiple models;

[0205] a number of models that the terminal supports at most;

[0206] a minimum number of ports required by the terminal for estimating channel information;

[0207] a ratio of a minimum number of ports required by the terminal for estimating channel information to a number of ports corresponding to channel information to be estimated.

[0208] Exemplarily, the indication of whether the terminal supports the capability of estimating channel information of all ports using channel information of part of the ports includes an indication of whether the terminal supports an AI-based low-overhead pilot channel estimation method.

[0209] Exemplarily, the ratio of the minimum number of ports required by the terminal for estimating channel information to the number of ports corresponding to the channel information to be estimated can be a ratio of the minimum number of ports required by the terminal for estimating channel information to a number of all ports, i.e., the ports corresponding to the channel information to be estimated are all the ports. Optionally, the ratio is used to determine the minimum number of ports required by the terminal for estimating channel information. For example, a minimum value of the ratio is s, which indicates that the terminal needs at least s x P ports for estimating channel information, where P represents a number of all the ports.

[0210] In this embodiment, the capability information can be sent by the network-side device as auxiliary information of the at least one first reference signal, so as to further save resource overhead of the reference signal. For example, in the case that the terminal supports the capability of estimating channel information of all ports by using channel information of part of ports, the network-side device sends the first configuration information and the at least one first reference signal to the terminal, thereby avoiding the case that the terminal does not support the capability of estimating channel information of all ports by using channel information of part of ports, and reducing resource overhead caused by sending unnecessary first configuration information and at least one first reference signal.

[0211] The scheme of the present application will be described below in combination with specific embodiments.

[0212] Embodiment 1

[0213] This embodiment describes a process and method for jointly determining a transmission port pattern by a terminal and a network-side device. The beneficial effect of this embodiment is that the network-side device and the terminal can align the understanding of the ports used for transmitting the reference signal.

[0214] FIG. 6 is a schematic flowchart of a reporting method 300 of a first reporting information according to an embodiment of the present application.

[0215] As shown in FIG. 6, the reporting method 300 can include:

[0216] S301, a terminal reports capability information of the terminal to a network-side device.

[0217] The capability information is used to indicate at least one of the following:

[0218] an indication of whether the terminal supports the capability of estimating channel information of all ports by using channel information of part of ports;

[0219] an indication of whether the terminal supports multiple models;

[0220] a number of models supported by the terminal at most;

[0221] a minimum number of ports required by the terminal for estimating channel information;

[0222] a ratio of a minimum number of ports required by the terminal for estimating channel information to a number of ports corresponding to channel information to be estimated.

[0223] Exemplarily, the ratio of the minimum number of ports required by the terminal to estimate the channel information to the number of ports corresponding to the channel information to be estimated can be: the ratio of the minimum number of ports required by the terminal to estimate the channel information to the number of all ports, i.e., the ports corresponding to the channel information to be estimated are all ports. Alternatively, the ratio is used to determine the minimum number of ports required by the terminal to estimate the channel information. For example, the minimum value of the ratio is s, which indicates that the terminal needs at least s x P ports to estimate the channel information, and P represents the number of all ports.

[0224] S302, the terminal receives first configuration information from the network side device.

[0225] The first configuration information is related configuration of at least one first reference signal for data collection / model training. The network side device sends the first configuration information, and the first configuration information is used to configure at least one first resource, and the terminal performs model training by measuring at least one first reference signal resource transmitted on the at least one first resource. The first configuration information also indicates the topology form of the port set associated with the at least one first resource, for example, the number of ports N1 in the first dimension and the number of ports N2 in the second dimension. It should be understood that for a dual-polarized array, the total number of ports is P = 2N1N2, where 2 represents two polarization directions. Alternatively, the network side device can also indicate or agree on the port spacing in the first dimension direction and the second dimension direction. When the number of ports in a certain dimension is 1, the port spacing corresponding to this dimension can not be indicated.

[0226] Alternatively, the first configuration information can configure the use of the at least one first resource as model training or determining a port pattern, for example, configure its usage as training.

[0227] Alternatively, for each first resource, the first configuration information also indicates an associated first identification number. Alternatively, the first identification number can be one of a resource identification number, a dataset identification number (dataset ID), an associated identification number (associated ID), a beam identification number (beam ID), a cell identification number (cell ID), or an identification number of an AI model. For example, first resources with the same beam identification number indicate that these first resources use the same transmission beam and further can use the same other physical parameters (such as network side device array tilt, network side device height, etc.), which will be used for training of the same model. At the same time, the same number / index of ports of different first resources with the same first identification number can be considered to correspond to the same port.

[0228] Optionally, the plurality of first resources are divided into a plurality of groups or sets, such as CSI-RS resource sets (CSI-RS resource set) or CSI-RS resource groups (CSI-RS resource group). The reference signals of the same resource group can use the same transmission beam, and further can use the same other physical parameters (such as network side device array tilt angle, network side device height, etc.), for example, the same resource group is used for training of the same model, and the ports with the same sequence number / index of different first resources in the same resource group can be considered to correspond to the same port. For each resource group, the first configuration information further indicates an associated second identification number. Optionally, the second identification number can be one of the following: the identification number of the first resource group / set, the dataset ID, the associated ID, the beam ID, the cell ID, or the identification number of the AI model. In some possible embodiments, the second identification number can be determined according to certain rules, for example, according to the order of the network side device configuration, for example, the second identification number of the first first resource group configured first is 0, the second identification number of the second first resource group configured second is 1, and so on.

[0229] S303, the terminal receives third configuration information from the network side device.

[0230] The third configuration information is related configuration information for training and reporting of the terminal, that is, the network side device configures the terminal to train and report the AI model through the third configuration information. The third configuration information indicates at least one of the following information:

[0231] Case 1:

[0232] The third configuration information indicates related information of the set of available ports, for example, indicates one or more sets of available ports.

[0233] Optionally, the indication of any one set of available ports can be indicated by a bit map.

[0234] For example, each bit in the bitmap can represent whether each port is a usable port (in which case each bit corresponds to one port), or whether each pair of ports (e.g., a pair of dual-polarized antenna ports) is a usable port (in which case each bit corresponds to one pair of ports), or whether each port subset is a usable port (in which case each bit corresponds to one port subset, and whether the ports in the port subset are usable can be described below). A port subset contains at least one port. Some possible port subset patterns (which can also be understood as the topology of the ports in the subset) are shown in FIG. 7, which can be configured by the network-side device or by default by the protocol. FIG. 8 shows an example of indicating a set of usable ports based on a bitmap, in which there are four port subsets (indicated by solid and dashed boxes), two of which (indicated by solid boxes) are usable port subsets. Further, when a port subset is usable, it can mean that all the ports in the port subset are usable ports, or only some of the ports in the port subset are usable ports. For example, as shown in FIG. 9 (the ports in the solid boxes are usable ports), which ports in the usable port subset are usable ports can be configured by the network-side device or by default by the protocol. Alternatively, several possible port selection modes can be configured or predefined for the port subset. For example, assuming the port subset pattern is shown in (b) of FIG. 7, the network-side device can indicate or by default by the protocol indicate which ports in the usable port subset are usable ports in two port selection modes, such as (c) of FIG. 9 and (d) of FIG. 9. For each usable port subset, the network-side device can indicate the port selection mode, such as indicating the port selection mode as (c) of FIG. 9.

[0235] It should be understood that the set of usable ports can be referred to as a set of reportable ports or the candidate port set described above.

[0236] Optionally, any usable set of ports can be indicated by the index, identifier, or sequence number of a single usable port / port pair (e.g., a dual-polarized antenna port pair) / port subset, or by the number of combinations. Other relevant explanations can be found in the bitmap section above. The numbering / arrangement order of ports / port pairs (e.g., dual-polarized antenna port pairs) / port subsets can be in the following order: first dimension, then second dimension (if polarization direction is considered, then first dimension, then second dimension, and finally polarization direction), or second dimension, then first dimension (if polarization direction is considered, then second dimension, then first dimension, and finally polarization direction). In some embodiments, the first dimension can be vertical and the second dimension horizontal; in other embodiments, the first dimension can be horizontal and the second dimension vertical.

[0237] Scenario 2:

[0238] The third configuration information indicates a second port set, which is the set of ports that the terminal must report. In other words, the ports reported by the terminal (i.e., at least one first port or any one of at least one port pattern derived from at least one first port) must include all ports in the second port set. The specific indication method of this second port set can be found in Case 1.

[0239] Optionally, the terminal can select more ports for reporting based on this second set of ports.

[0240] Optionally, network-side device configurations or protocols may stipulate rules or restrictions that terminals must adhere to when determining the port to report. For example, the above restrictions can be one or a combination of the following:

[0241] The distance between the reported ports must be greater than a certain threshold. Optionally, the distance between ports can be determined based on the array topology indicated by the network-side device, such as the Manhattan distance, then the indices for the two dimensions are respectively... The port #1 and the corresponding index are Port #2, the distance between the two ports can be expressed as Optionally, the distance between ports can be determined based on the array topology configured on the network-side devices and the port spacing in two dimensions, such as Euclidean distance, where the indices for the two dimensions are respectively... The port #1 and the corresponding index are Port #2, the distance between the two ports can be expressed as Where d1 represents the spacing of ports in the first dimension, and d2 represents the spacing of ports in the second dimension. d1 and d2 can be configured by the network side device or by default of the protocol.

[0242] The increased number of ports (i.e. the other reported ports in addition to the ports in the second port set) must satisfy a certain requirement, such as must be a multiple of 2, or a multiple of 4.

[0243] The last reported number of ports must satisfy a certain requirement, such as must be one of 4, 8, 12, 24, 32.

[0244] The last reported number of ports cannot exceed a certain maximum value.

[0245] The last reported port arrangement must ensure uniform distribution in the first dimension or the second dimension.

[0246] It should be understood that the rules or restrictions that the terminal needs to comply with when determining the reported ports can be restrictions or rules for one port pattern, but the present application is not limited thereto.

[0247] Case 3:

[0248] The reported ports or port patterns are completely determined by the terminal, which can be regarded as a special case of case 2, equivalent to the case where the set of ports that must be contained (i.e. the second port set) configured by the network side device in case 2 is empty. In this case, there is no need to indicate the set of ports that must be contained, i.e. the set of ports that must be contained by default of the protocol is empty. Optionally, the network side device can configure or the protocol can agree that the terminal needs to comply with rules or restrictions when determining the reported ports or port patterns. For details, please refer to case 2.

[0249] In this embodiment, the third configuration information can also be used to indicate at least one of the following:

[0250] The uplink resource used by the terminal to report, such as PUSCH resource or PUCCH resource.

[0251] The threshold value of the terminal's estimated performance (which is used by the terminal to determine the reported ports or port patterns), which can be of the following types:

[0252] Mean squared error (MSE);

[0253] Normalized mean squared error (NMSE);

[0254] Squared Generalized Cosine Similarity (SGCS)

[0255] block error rate (BLER).

[0256] The third identifier is an identifier associated with the third configuration information, for example, reportConfigID.

[0257] In some possible embodiments, the first configuration information and the third configuration information are indicated in the same signaling. Alternatively, the third configuration information includes the first configuration information, or the first configuration information includes the third configuration information.

[0258] It is worth noting that the advantage of limiting the possibility of port pattern selected by the terminal is that the possibility of different terminals sharing the same transmission pattern can be improved, so that different terminals can use the same set of reference signals for channel measurement in the channel information estimation process as much as possible, or the intersection between the transmission patterns of different terminals can be improved as much as possible, which helps to reduce the resource overhead of reference signals in the channel information estimation process.

[0259] S304, the terminal receives at least one first reference signal from the network side device.

[0260] The terminal receives at least one first reference signal sent by the network side device on at least one first resource configured by the first configuration information.

[0261] S305, the terminal sends first reporting information to the network side device.

[0262] The terminal determines at least one first port reported by the terminal based on the received at least one first reference signal. Optionally, the at least one first port can be divided into at least one port pattern, and correspondingly, the terminal can report the at least one port pattern. For example, the terminal sends the first reporting information to the network side device, which is used to indicate the at least one first port or the at least one port pattern determined by the terminal.

[0263] The process of determining the at least one first port or the at least one port pattern by the terminal is described briefly as follows.

[0264] The terminal can determine, through training, for example, using a stochastic sampling network, a port set with the minimum number of ports that meets the threshold of inference performance and the requirement of network-side device configuration (for example, the rule configured by the network-side device), which can be directly used as the at least one first port or as a port pattern. For the case where the network-side device configures a set of available ports (for example, case 1 in S303), the terminal can determine the inference performance for each set of available ports, and select a set of ports with the minimum number of ports that meets the threshold of inference performance, which can be directly used as the at least one first port or as a port pattern.

[0265] After the terminal determines the at least one first port or the at least one port pattern, the terminal reports first reporting information in the reporting resource configured by the network-side device. The first reporting information is used to inform the network-side device of the at least one first port selected by the terminal, and in the case where the at least one first port is divided into at least one port pattern, the first reporting information is used to inform the network-side device of the at least one port pattern selected by the terminal. For example, the first reporting information indicates N port patterns. The value of N can be configured by the network-side device or specified by a protocol. In some possible embodiments, the network-side device configures or the protocol specifies a maximum value of N, and the actual number of port patterns indicated by the first reporting information can be less than the configured value or a preset value.

[0266] For case 1 in S303, the first reporting information can indicate the at least one first port or the N port patterns through the index / sequence / identification number of the candidate port set corresponding to the at least one first port or the port pattern, or through the combination number or through a bit map (each bit corresponds to one). For case 2 in S303 or case 3 in S303, the first reporting information can indicate the port selected by the terminal (i.e., the at least one first port) or the port pattern selected by the terminal through the following methods:

[0267] Method 1: The first reporting information indicates the port or the port pattern through a bit map.

[0268] Optionally, the length of the bit map can be N1N2 or 2N1N2, or 2N1N2-N s , where N s represents the number of ports that must be included. The length of the bit map is N1N2, which indicates that a pair of ports (for example, a pair of polarized antenna ports) are selected at the same time.

[0269] Method 2: The first reporting information indicates the port or the port pattern through the index / sequence / identification number corresponding to the port or through the combination number.

[0270] Optionally, the first reporting information does not need to indicate the ports that must be included.

[0271] Optionally, the first reporting information further indicates the number of selected ports or the number of ports in the selected port pattern, or indicates the difference between the total number of ports in the selected port pattern and the total number of ports that must be included.

[0272] Method 3: The terminal reports the selected port or the selected port pattern in units of one or more port sets, for example, the first reporting information can indicate at least one first port set, indicating that the selected port or the selected port pattern includes part or all of the ports in the indicated at least one first port set, which can be used as a transmission port pattern for the network side device to send reference signals.

[0273] Optionally, the first reporting information can indicate the at least one first port set through the index / sequence number / identification number, combination number or bitmap corresponding to the port set.

[0274] Optionally, the first reporting information further needs to explicitly or implicitly indicate the total number of the at least one first port set reported.

[0275] Optionally, the first reporting information further needs to indicate part or all of the ports in each first port set. For example, the first reporting information can indicate the selected port in the at least one first port set or the port belonging to the selected port pattern of the terminal.

[0276] Optionally, the network side device can pre-configure or protocol-predefine multiple port selection modes, for example, as shown in FIG. 9, the first reporting information will indicate the port selection mode of each first port set.

[0277] Optionally, the terminal can use one signaling to indicate the selected port in all the first port sets selected by the terminal or the port belonging to the selected port pattern of the terminal. For example, use one signaling to indicate the port selection mode of all the first port sets selected by the terminal. That is, the port selection mode of all the first port sets selected by the terminal can be the same.

[0278] Optionally, each port in each first port set selected by the terminal is by default included in the port pattern, or the selected port in each first port set selected by the terminal is protocol default or configured by the network side device, for example, the port with the smallest sequence number / index and / or the port corresponding to another polarization direction.

[0279] Optionally, each port set corresponding to the selected port or the selected port pattern of the terminal can adopt the same port selection mode.

[0280] Optionally, each port set corresponding to the port pattern selected by the terminal can adopt the same port selection manner.

[0281] In some possible embodiments, the first reporting information indicates at least one of the following identification information:

[0282] A first identification number associated with the first resource.

[0283] A second identification number associated with the first resource group.

[0284] A third identification number associated with the third configuration information, for example, in the case where each configuration information is associated with only one set of reference signals with the same transmission beam.

[0285] An identification number of the AI model, for example, an identification number of the AI model.

[0286] In some possible embodiments, there can be no port set in the network-side device-configured reportable port set (for example, the candidate port set, or at least one port or port pattern satisfying the configured or predefined limit) that can satisfy the threshold value of the inference performance, and the terminal can report an indication information indicating the occurrence of the event. For example, a bit can be reported, where 1 indicates the occurrence of the event, and 0 indicates the non-occurrence of the event.

[0287] Optionally, the identification number of the AI unit / AI model can be a model identification number, an AI structure identification, an AI algorithm identification, or an identification of a specific data set associated with the AI unit / AI model, or an identification of a specific scene, environment, region, cell, channel feature, or device associated with the AI / ML, or an identification of a function, feature, capability, or module associated with the AI / ML, and the present application does not make a specific limitation thereon.

[0288] It should be noted that in other alternative embodiments, the first configuration information can include the third configuration information, or the third configuration information can include the first configuration information, or the first configuration information and the third configuration information can be indicated by the same signaling, and the present application does not make a specific limitation thereon.

[0289] It should be further noted that different identification information, including the identification number of the AI model, has a one-to-one correspondence with the AI model of the terminal. For example, the second identification number and the third identification number, the terminal can train an AI model using the associated reference signal, and for each identification number, an AI model will be trained, and the model can be assigned an identification number of the AI model (as described above, the identification number can be reported). These identification information will be used by the network-side device to indicate the terminal to use a suitable AI model for channel estimation or inference to obtain complete channel information when sending low-overhead reference signals in the future.

[0290] Embodiment 2

[0291] In this embodiment, after receiving the first reported information reported by the terminal, the network side device configures at least one second reference signal for channel measurement, for example, at least one second resource for transmitting the at least one second reference signal and the port of the at least one second reference signal. Correspondingly, the terminal performs channel information estimation based on the at least one second reference signal received on the at least one second resource.

[0292] FIG. 10 is a schematic flowchart of a method 400 for estimating channel information of all ports according to an embodiment of the present application.

[0293] As shown in FIG. 10, the estimation method 400 can include the following steps.

[0294] S401, the terminal receives second configuration information from the network side device.

[0295] The second configuration information sent by the network side device is used to configure at least one second reference signal for channel measurement. The second configuration information indicates that a plurality of second reference signals are used for channel measurement. The plurality of second reference signals can be configured as different resource types or time domain behaviors, for example, reference signal 1 is periodic and reference signal 2 is aperiodic. Different second reference signals can have different port numbers, and the port number of each second reference signal is less than the port number of the corresponding first reference signal. The total number of ports of the at least one second reference signal is less than the number of ports of the corresponding first reference signal.

[0296] Optionally, the second configuration information can configure the purpose of the at least one second reference signal as channel measurement, for example, configure the usage as channel measurement (channel measurement).

[0297] Optionally, the second configuration information further indicates at least one of the following identification information:

[0298] a first identification number of the first resource;

[0299] a second identification number of the first resource group;

[0300] a third identification number of the third configuration information;

[0301] an identification number of the AI model.

[0302] Optionally, the second configuration information further needs to indicate the ports corresponding to the ports of the plurality of second reference signals, which can be indicated by the following methods:

[0303] Method 1: indicates the topology of the array or port set (e.g. can indicate the number of ports in the first dimension and the number of ports in the second dimension), and indicates the location (including polarization direction) of the port of each of the above-mentioned second reference signals on the array topology.

[0304] For example, as shown in (a) of FIG. 11, the second configuration information can indicate the location of the port of the reference signal 1 and the port of the reference signal 2 on the array. In some embodiments, the order / position of the port in the first dimension and the second dimension and the polarization direction can be indicated. In other embodiments, further a bitmap (each bit in the bitmap corresponds to a port) or a combination number or an index / serial number / identification number of the port can be used for indication, where the port is arranged in the order of first dimension, then second dimension, and finally polarization direction, or arranged in the order of second dimension, then first dimension, and finally polarization direction.

[0305] Method 2: indicates the correspondence between the port of each of the above-mentioned second reference signals and the port of the corresponding first reference signal (indicated by the third configuration information). Wherein, the port of the at least one first reference signal used for training has a one-to-one correspondence with the location (including polarization direction) on the array. Optionally, the port of the first reference signal can be arranged in the order of first dimension, then second dimension, and finally polarization direction, or arranged in the order of second dimension, then first dimension, and finally polarization direction.

[0306] For example, as shown in (b) of FIG. 11, if the number of ports of the at least one first reference signal used for training is P=2N1N2, then it is necessary to indicate which one of the P ports is the port of the above-mentioned at least one second reference signal. Further, a bitmap or a combination number or an index / serial number / identification number of the port can be used for indication.

[0307] It should be noted that for one second reference signal, the corresponding first reference signal can be determined according to the indicated identification information. For example, if the first identification number or the second identification number is indicated, the first reference signal corresponding to the identification number is the corresponding first reference signal; if the third identification number is indicated, the corresponding first reference signal is the first reference signal indicated by the third configuration information; if the identification number of the AI model is indicated, the corresponding first reference signal is the first reference signal used for training the model corresponding to the identification number.

[0308] The association relationship between the port of the above-mentioned at least one second reference signal and the port of the corresponding first reference signal used for training, or the location on the array topology, is completely different or not completely the same. In other words, the port of the corresponding first reference signal of these second reference signal ports can be different.

[0309] S402, the terminal receives at least one second reference signal.

[0310] The terminal receives at least one second reference signal on at least one second resource indicated by the second configuration information.

[0311] S403, the terminal estimates channel information based on measurement of the at least one second reference signal.

[0312] The terminal measures the at least one second reference signal, and infers channel information corresponding to P ports based on the identification information in the second configuration information and a suitable AI model, for subsequent reporting.

[0313] In some scenarios, different terminals have reference signals corresponding to different port patterns. Generally, the network side device needs to configure different second reference signals for different terminals, which will result in a large overall overhead of the second reference signals. In the embodiment, the network side device can configure a periodic second reference signal for all terminals to use, which corresponds to the intersection (for example, a set of ports that must be included) of the port patterns reported by all terminals, and then configure a non-periodic second reference signal for each terminal, which can be triggered according to actual measurement requirements. Since a common reference signal is configured for all users, repeated transmission is avoided, and therefore the overhead of the at least one second reference signal can be greatly reduced.

[0314] Of course, in some possible embodiments, the network side device can send the finally determined port pattern to the terminal, so that the terminal re-trains or receives the second reference signal. The advantage of re-training is that subsequent second reference signals can be shared by different terminals.
