[0001] Cross Reference to Related Applications

[0067] In order to better understand the embodiments of the present application, the related technologies of the present application are described.
[0068] (1) Artificial Intelligence (AI).
[0069] AI has been widely applied in various fields. It is an important task for future wireless communication networks to integrate artificial intelligence into wireless communication networks and significantly improve technical indicators such as throughput, delay, and user capacity. There are various implementation methods for AI modules, such as neural networks, decision trees, support vector machines, and Bayesian classifiers. The present application takes the neural network as an example for illustration, but the specific type of the AI module is not limited.
[0070] FIG. 2 is an example of a structure of a neural network according to an embodiment of the present application.
[0071] 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 the neural network as an example for illustration, but the specific type of the AI module is not limited.
[0072] FIG. 3 is an example of a structure of a neuron according to an embodiment of the present application.
[0073] 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.
[0074] 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 predicted output f(x) can be obtained according to the input x, and the difference between the predicted 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 make the value of the above loss function reach the minimum, and the smaller the loss value, the closer the AI model is to the true situation.
[0075] 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 layer 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 preset number of learning times is reached.
[0076] The optimization algorithm can be Gradient Descent, Stochastic Gradient Descent (SGD), mini-batch gradient descent, Momentum, Stochastic Gradient Descent with Momentum (e.g. Nesterov), Adaptive Gradient Descent (Adagrad), Adadelta, root mean square prop (RMSprop), Adaptive Moment Estimation (Adam), etc. When error backpropagation is performed, the optimization algorithm 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, and obtain the gradient, and then pass the gradient to the previous layer.
[0077] Depending on the type of solution, the AI algorithm and AI model used can also differ.
[0078] Generally, the main method of improving the performance of a 5G network by using AI is to enhance or replace the existing algorithms or processing modules by using neural network-based algorithms and AI models. In specific scenarios, neural network-based algorithms and AI models can achieve better performance than deterministic algorithms. The neural network includes a deep neural network, a convolutional neural network, a recurrent neural network, etc. With existing AI tools, the construction, training, and verification of a neural network can be achieved.
[0079] Replacing traditional modules in a system with AI / machine learning (ML) methods can effectively improve the performance of the system.
[0080] It should be noted that 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 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. The specific data set can include the input and / or output of the AI unit / AI model.
[0081] Alternatively, the identification of the AI unit / AI model can be 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.
[0082] (2) Fine-tuning.
[0083] In practice, due to the small size of the real-time collected data set, directly training the neural network on the small-scale data set can cause overfitting, that is, the neural network can achieve good convergence or inference accuracy on the training set, but the convergence or inference accuracy on the validation set or test set is poor, also known as the generalization problem of the neural network. In order to improve the generalization ability, the common method is to pre-train the neural network based on a large amount of offline collected data, and then fine-tune the pre-trained neural network parameters or structure with real-time collected data to adapt the neural network to the actual environment. If fine-tuning only updates the parameters of the neural network, it can be considered that fine-tuning is a training process based on the parameters of the pre-trained neural network as initialization. The fine-tuning stage can freeze the parameters of part of the layers. Generally, the parameters of the layers close to the input end are frozen to retain the coarse-grained features learned from the large-scale data set, and the parameters of the layers close to the output end are fine-tuned to adapt the network to the fine-grained features of the actual environment. The less the data amount of the fine-tuning stage, the more layers are frozen, and only a small number of layers close to the output end are fine-tuned. If fine-tuning updates the structure of the neural network, the structure of the last few layers of the neural network can be fine-tuned, such as adding an additional layer before the output layer, adjusting the number of neurons in the last few layers, and the like. After the structure is changed, the parameters of the neural network can be further updated using the above parameter updating method.
[0084] Generalization problem of neural network:
[0085] Generalization refers to the ability of a neural network to produce relatively accurate outputs for data that it has not encountered during training (learning). In the context of wireless transmission environments, variations in hardware implementations of transceivers (such as the number of antennas, beam patterns, etc.), there are three solutions to the generalization problem for neural network-based wireless communication systems: 1) The first is to train different neural networks under different conditions (such as different cells, different regions, different motion speeds, and different channel conditions). Each condition corresponds to a set of neural network parameters or structures. As the actual environment changes, the parameters of the neural network are adjusted to ensure the accuracy of the neural network's inference. The second is to train a neural network based on a mixed data set under multiple conditions, so that the neural network can adapt to multiple conditions to improve the robustness of the neural network to environmental changes and avoid frequent switching. The third is fine-tuning: under new conditions, a set of data is collected, and the parameters or structure of the original neural network are fine-tuned. These three modes have their own advantages and disadvantages: the first scheme performs well under different transmission conditions, but requires storage of multiple neural network parameters or structures and switching as needed, which may result in additional signaling overhead, model management complexity, and frequent switching. The second scheme is a set of neural network parameters or structures that can be applied to multiple conditions, but cannot achieve optimal performance under each condition. The third scheme can quickly adapt the neural network to various new scenarios, but requires collecting new data and performing neural network model training, which is limited by factors such as the similarity between the pre-trained data set and the newly collected data, the size of the new data, etc.
[0086] Label:
[0087] In machine learning and deep learning, a label or ground truth label typically refers to the identification or annotation of the true class or target value of a data sample. The label is used to represent the information that the model should learn and predict given an input data sample, for example:
[0088] Label in classification task: The label represents which class the data sample belongs to. For example, for image classification, each image sample has a label representing the class or probability of the object or scene contained in the image, such as "dog" or "cat", or the probability of belonging to "dog" or "cat".
[0089] Label in object detection: The label usually includes the location information (bounding box) and class information of the object. Each label identifies a target object in the image, including its location and class.
[0090] Label in time series prediction or regression task: The label usually represents a continuous or real-valued target to be predicted. For example, the label in a house price prediction task can be the predicted future house sales price.
[0091] Label in sequence labeling: In natural language processing, labels in sequence labeling tasks are often used for tasks such as part-of-speech tagging, named entity recognition, etc., where labels are used to represent the attributes or categories of each word or character in a text sequence.
[0092] It should be understood that labels are a key component in supervised learning tasks, used to train machine learning models. The model learns patterns and rules through comparison with true labels in order to make predictions or classifications on unseen data. The quality and accuracy of labels are crucial to the performance of the model.
[0093] (3) Reporting of interference information in New Radio (NR) protocol.
[0094] Related description of interference measurement in NR protocol:
[0095] The quantity related to interference measurement in NR is the Signal to Interference plus Noise Ratio (SINR), which includes Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) and Layer 3 Signal to Interference plus Noise Ratio (L3-SINR). The interference information involved in this application can be layer 1 interference information or layer 3 interference information. For example, the SINR involved in this application can be L1-SINR or L3-SINR, which is not limited here. The difference between L1-SINR and L3-SINR is that L3-SINR can be obtained by smoothing filtering L1-SINR. In one implementation, the L3-SINR at time t can be calculated by L1-SINR at time t and N previous times.
[0096] Measurement of L1-SINR:
[0097] L1-SINR is obtained by UE through network configured Non-Zero Power (NZP) Channel State Information Reference Signal (CSI-RS) for channel measurement and / or Synchronization Signal / PBCH Block (SS / PBCH Block, SSB), and / or NZP CSI-RS for interference measurement or Channel State Information-Interference Measurement (CSI-IM).
[0098] When network configures one resource setting, which includes resource for channel measurement (resourceForChannelMeasurement), the resource setting can be used for channel measurement and interference measurement, so that SINR can be calculated. For example, UE can obtain channel and interference measurement through NZP CSI-RS for channel measurement and / or SSB, and then calculate SINR.
[0099] When network configures two resource settings, the resource configured by the first resource setting can be used for channel measurement, and the resource configured by the second resource setting can be used for interference measurement. For example, UE can obtain channel measurement through NZP CSI-RS for channel measurement and / or SSB, and obtain interference measurement through NZP CSI-RS for interference measurement or CSI-IM, and then calculate SINR. The number of SSB or CSI-RS resources in one resource set is equal to the number of CSI-IM resources or the number of NZP CSI-RS resources for interference measurement in one resource set. Through the order of SSB or NZP CSI-RS resources for channel measurement and NZP CSI-RS resources for interference measurement in the resource set, each SSB or NZP CSI-RS resource for channel measurement is associated with one CSI-IM resource or one NZP CSI-RS resource for interference measurement.
[0100] Reporting of L1-SINR:
[0101] For L1-SINR reporting with differential reporting, if the network indicates that the number of reference signals (RS) reported by the UE is 1 (e.g., the high layer parameter nrofReportedRS is 1), the UE reports the SINR with 7 bits, and the range of SINR is [-23, 40] dB with a step size of 0.5 dB. If the network indicates that the number of RS reported by the UE is greater than 1 (e.g., the high layer parameter nrofReportedRS is greater than 1 or the high layer parameter groupBasedBeamReporting is enabled), the maximum measured SINR value can be reported with 7 bits, and the differential SINR value can be reported with 4 bits, with a step size of 1 dB. When NZP CSI-RS is used for channel measurement or interference measurement, the reported L1-SINR value should not be compensated by power offset.
[0102] Inter-Cell Interference Coordination (ICIC):
[0103] ICIC is a technique used in mobile communication networks to manage and optimize interference between multiple base stations or cells. As mobile networks evolve towards higher data rates and denser network deployments, such as in LTE (Long Term Evolution), LTE-Advanced, and 5G networks, inter-cell interference becomes a significant problem because neighboring cells can use the same or partially overlapping spectrum to provide service.
[0104] Analysis of inter-cell interference problem:
[0105] In wireless communication networks, the limited availability of wireless spectrum resources, combined with the growing demand for spectrum, necessitates the most efficient possible use of spectrum. To meet this demand, network operators reuse the same frequency bands in geographically adjacent cells. However, this can result in user equipment (UE) at the edge of a cell experiencing interference from transmitters in neighboring cells. If not managed, inter-cell interference can degrade the overall performance of the network, particularly the data rates and Quality of Service (QoS) of edge users.
[0106] Method of Inter-Cell Interference Coordination:
[0107] To address this problem, ICIC techniques have been developed to coordinate, reduce, and manage these interferences through various strategies to improve network performance, particularly at the edge of the cell. ICIC mainly includes the following strategies:
[0108] Resource allocation: Cells can coordinate the use of different spectrum resources or resource blocks (RBs). For example, neighboring cells can avoid using the same resource blocks where they spatially overlap.
[0109] Power control: Base stations can adjust their transmit power, especially for edge users, to reduce interference to neighboring cells.
[0110] Inter-cell coordination: Through information exchange and coordination between base stations, more refined interference management can be achieved, such as through coordinated multipoint (CoMP) technology, which utilizes multiple cells to cooperatively provide service.
[0111] Dynamic spectrum allocation: Based on real-time interference and network load conditions, dynamically adjust the utilization mode and allocation of spectrum.
[0112] ICIC is a centralized or distributed system that communicates through the core of the network (such as the operator's network management system) or directly through the Xn interface between base stations. The goal of inter-cell interference coordination is to improve the capacity of the entire network, optimize user experience, and ensure efficient use of network resources.

When the first configuration information comprises the frequency domain reporting configuration, the first interference information comprises interference information on frequency domain resources configured in the frequency domain reporting configuration by the first device. When the first configuration information comprises the time domain reporting configuration and the frequency domain reporting configuration, the first interference information comprises interference information on target resources by the first device; the target resources comprise time domain resources configured in the time domain reporting configuration and frequency domain resources configured in the frequency domain reporting configuration.

The present application does not make specific limitations thereto.
[0126] In some embodiments, the time domain reporting configuration is configured to configure at least one of the following:
[0127] The first indication information is used to indicate that the reported interference information is associated with one or more time domain resource units.

[0130] The fourth indication information is used to indicate the reference time associated with the reported interference information.
[0131] The fifth indication information is used to indicate the time length of the time interval associated with the reported interference information.
[0132] Exemplarily, the start time can be the start time of the earliest time interval or time domain resource unit in time. For example, the start time can be the first time slot in the earliest time domain resource unit in time associated with the reported interference information. For example, the start time can also be the first time slot of the earliest time interval in time associated with the reported interference information.
[0133] The reference time is used to determine a starting time associated with the reported interference information, for example.

Compared with a scheme of configuring time domain resources associated with reported interference information through a bit map, configuring time domain resources associated with reported interference information through a prediction window can reduce bit overhead of indication, especially in a case where a number of time domain resource units is large.
[0137] In some embodiments, the second indication information includes a first offset value, and the first offset value is an offset value of the starting time relative to a reference time associated with the reported interference information.
[0138] Exemplarily, the first offset value can comprise one or more time intervals, or the first offset value can comprise one or more time domain resource units. For example, the first offset value can be indicated by a number of time intervals or time domain resource units. The first offset value can be a positive integer, a negative integer, or 0. When the first offset value is a positive integer, the starting time is after the reference time; when the first offset value is a negative integer, the starting time is before the reference time; and when the first offset value is 0, the starting time is the reference time.
[0139] In this embodiment, the starting time associated with the reported interference information is indicated by the first offset value, which can reduce the data amount of the second indication information, and further can save resource overhead when the second indication information or the first configuration information is transmitted.

For example, when the first configuration information is a CSI reporting configuration, the time domain resource unit configured by the first configuration information comprises a time domain resource unit for reporting CSI, or the time domain resource unit configured by the first configuration information is a time domain resource unit indicated in the CSI reporting configuration.
[0150] For example, the reference time is used to determine the starting time associated with the reported interference information. For example, the reference time and the first offset value described above can be used to determine the starting time. For example, assuming that the time domain resource unit of the reported CSI is the nth time slot, i.e., the reference time is the nth time slot, the starting time is the (n+m)th time slot, and m is the first offset value.

[0170] Exemplarily, the reference frequency domain position is used for determining a frequency domain start position associated with the reported interference information.
[0171] Exemplarily, the frequency domain length can be a continuous length in the frequency domain. For example, the frequency domain length can include at least one of the following: one or more subbands, one or more subband groups, one or more PRBs, one or more BWPs, one or more bandwidths, one or more frequency bands, one or more carriers, and one or more subcarriers. For another example, the frequency domain length can include one or more frequency domain intervals. Optionally, the frequency domain length can include a plurality of continuous frequency domain resource units, for example, the frequency domain length can include at least one of the following: a plurality of continuous subbands, a plurality of continuous subband groups, a plurality of continuous PRBs, a plurality of continuous BWPs, a plurality of continuous bandwidths, a plurality of continuous frequency bands, a plurality of continuous carriers, and a plurality of continuous subcarriers. The network indicates a number of continuous frequency domain resource units included in the frequency domain length. Optionally, the frequency domain length can include a plurality of continuous frequency domain intervals. The network indicates a number of continuous frequency domain intervals included in the frequency domain length.
[0172] Exemplarily, the length of the frequency domain interval can be an interval of two adjacent interference values in the frequency domain. For example, the length of the frequency domain interval can include at least one of the following: one or more subbands, one or more subband groups, one or more PRBs, one or more BWPs, one or more bandwidths, one or more frequency bands, one or more carriers, and one or more subcarriers. Optionally, the frequency domain interval can include a plurality of continuous frequency domain resource units, for example, the frequency domain interval can include at least one of the following: a plurality of continuous subbands, a plurality of continuous subband groups, a plurality of continuous PRBs, a plurality of continuous BWPs, a plurality of continuous bandwidths, a plurality of continuous frequency bands, a plurality of continuous carriers, and a plurality of continuous subcarriers.

Optionally, the ninth indication information is used to indicate the reference frequency domain position of the prediction window. Optionally, the tenth indication information is used to indicate the length of the frequency domain interval in the prediction window. Compared with the scheme of configuring the frequency domain resource associated with the reported interference information through a bit map, the scheme of configuring the frequency domain resource associated with the reported interference information through a prediction window can reduce the bit overhead of indication, especially in the case of a large number of frequency domain resource units, which can effectively reduce the bit overhead of indication.
[0174] In some embodiments, the seventh indication information includes a second offset value, and the second offset value is an offset value of the frequency domain start position relative to the reference frequency domain position associated with the reported interference information.
[0175] Optionally, the second offset value can include one or more frequency domain resource units, or the second offset value can include one or more frequency domain intervals. For example, the number of frequency domain resource units or the number of frequency domain intervals can be indicated. The second offset value can be a positive integer, a negative integer, or 0. When the second offset value is a positive integer, it means that the frequency of the frequency domain start position is greater than the frequency of the reference frequency domain position associated with the interference information, or the index of the frequency domain resource unit associated with the frequency domain start position is greater than the index of the frequency domain resource unit associated with the reference frequency domain position associated with the interference information. When the second offset value is a negative integer, it means that the frequency of the frequency domain start position is less than the frequency of the reference frequency domain position associated with the interference information, or the index of the frequency domain resource unit associated with the frequency domain start position is less than the index of the frequency domain resource unit associated with the reference frequency domain position associated with the interference information. When the second offset value is 0, it means that the frequency of the frequency domain start position is equal to the frequency of the reference frequency domain position associated with the interference information, or the index of the frequency domain resource unit associated with the frequency domain start position is equal to the index of the frequency domain resource unit associated with the reference frequency domain position associated with the interference information. The index of the frequency domain resource unit z, such as the zth sub-band, the zth PRB, etc.
[0176] In this embodiment, the second offset value is used to indicate the frequency domain start position associated with the reported interference information, which can reduce the data amount of the seventh indication information, and further can save the resource overhead of transmitting the seventh indication information or the first configuration information.
[0177] In some embodiments, the eighth indication information includes at least one of the following:
[0178] The number of consecutive frequency domain intervals;
[0179] The number of consecutive frequency domain resource units.
[0180] In this embodiment, by indicating the frequency domain length associated with the reported interference information through the number of consecutive frequency domain intervals or the number of consecutive frequency domain resource units, the data volume of the eighth indication information can be reduced, thereby saving resource overhead when transmitting the eighth indication information or the first configuration information.
[0181] In some embodiments, the reference frequency domain location is determined according to at least one of the following:
[0182] Frequency domain resource elements associated with CSI reference resources;
[0183] Frequency domain resource units indicated in the CSI resource configuration;
[0184] Frequency domain resource units reported to CSI;
[0185] CSI reports the frequency domain resource units indicated in the configuration.
[0186] For example, the CSI reference resource is used to transmit CSI reference signals.
[0187] For example, the reference frequency domain location is determined based on at least one of the following: the starting position of the frequency domain resource unit associated with the CSI reference resource, the starting position of the frequency domain resource unit indicated in the CSI resource configuration, the starting position of the frequency domain resource unit that reports to the CSI, and the starting position of the frequency domain resource unit indicated in the CSI reporting configuration.
[0188] For example, taking the frequency domain resource unit indicated in the CSI reporting configuration as an example, the reference frequency domain position can be determined based on at least one of the following: the first frequency domain resource unit indicated in the CSI reporting configuration, or the last frequency domain resource unit. Optionally, the frequency domain resource unit indicated in the CSI reporting configuration may include multiple consecutive or non-consecutive frequency domain resource units. Optionally, the frequency domain resource unit indicated in the CSI reporting configuration may include the frequency domain resource unit associated with the BWP ID associated with the CSI reporting configuration. For example, the reference frequency domain position may be the start or center position of the first PRB or the first subband of the BWP associated with the CSI reporting configuration. Furthermore, when the first configuration information is a CSI reporting configuration, the reference frequency domain position can be determined based on the first frequency domain resource unit of the BWP associated with the first configuration information.
[0189] Exemplarily, the reference frequency domain position is determined according to at least one of: an i th frequency domain resource unit associated with the CSI reference resource, a j th frequency domain resource unit indicated in the CSI resource configuration, a j th frequency domain resource unit for reporting the CSI, a j th frequency domain resource unit indicated in the CSI reporting configuration. For example, the reference frequency domain position is determined according to at least one of: a starting position of an i th frequency domain resource unit associated with the CSI reference resource, a starting position of an i th frequency domain resource unit indicated in the CSI resource configuration, a starting position of a j th frequency domain resource unit for reporting the CSI, a starting position of a j th frequency domain resource unit indicated in the CSI reporting configuration. i and j are positive integers. The i th or the j th can be the first or the last.
[0190] It should be noted that the frequency domain resource unit for reporting the CSI is an uplink resource unit for carrying the reported CSI. Optionally, the frequency domain resource unit indicated in the CSI resource configuration can be a frequency domain resource unit for channel measurement or interference measurement. Optionally, the frequency domain resource unit indicated in the CSI reporting configuration can be a frequency domain resource unit associated with the reported interference information; for example, when the first configuration information is the CSI reporting configuration, the frequency domain resource unit configured by the first configuration information (for example, the frequency domain resource unit configured by the reporting frequency domain configuration) is the frequency domain resource unit indicated in the CSI reporting configuration.
[0191] In some embodiments, the frequency domain interval includes one or more frequency domain resource units.
[0192] Exemplarily, the frequency domain interval includes a plurality of consecutive frequency domain resource units; for example, the frequency domain interval includes a plurality of consecutive frequency domain resource units.
[0193] In some embodiments, the first configuration information further includes at least one of:
[0194] one or more cell identities associated with the reported interference information;
[0195] one or more reference signal identities associated with the reported interference information;
[0196] one or more reference signal configuration identities associated with the reported interference information;
[0197] one or more Transmission Reception Point (TRP) identities associated with the reported interference information;
[0198] one or more port identities associated with the reported interference information.
[0199] It should be understood that the first configuration information can also include other information associated with the reported interference information, for example, the first configuration information can also include a beam identifier associated with the reported interference information, and the like, which is not limited in the present application.
[0200] In some embodiments, the reference signal configuration identifying the associated reference signal configuration comprises at least one of:
[0201] a first resource set;
[0202] a second resource set and a third resource set;
[0203] The first interference information comprises interference information on part or all of the resources in the first resource set.
[0204] The interference information measured on the second resource set is used by the first device to predict the interference information on the third resource set, and the first interference information comprises interference information on part or all of the resources in the third resource set.
[0205] Exemplarily, the first interference information comprises predicted or measured interference information for part or all of the resources in the first resource set.
[0206] Exemplarily, the first resource set, the first resource set, or the third resource set is a reference signal resource set, i.e., comprising one or more reference signal resources. In other words, the first interference information comprises first interference information on part or all of the reference signal resources in the first resource set; the interference information measured on the second resource set is used by the first device to predict the interference information on the third resource set, and the first interference information comprises interference information on part or all of the reference signal resources in the third resource set.
[0207] Exemplarily, the first resource set, the first resource set, or the third resource set can comprise at least one of: time domain resources, frequency domain resources, cell identifiers, reference signal identifiers, reference signal resource identifiers, reference signal resource set identifiers, reference signal resource indications, reference signal configuration identifiers, identifiers of TRPs, port identifiers. Of course, other types of resources or resource-related information can also be included, which is not limited in the present application.
[0208] In the present embodiment, by configuring multiple resource sets, the reporting flexibility of the first device reporting interference information can be improved, for example, the first device can determine which reference signal resources on the first resource set or the third resource set to report interference information, or determine which interference measurement on the second resource set to use for interference prediction, according to the prediction capability of the device, the design of the AI model, etc.
[0209] In some embodiments, the reporting quantity comprises a format of the first interference information; wherein the format of the first interference information is a first format or a second format, the format of the first interference information comprises an interference value and a confidence level when the format of the first interference information is the first format, and the format of the first interference information comprises an interference value when the format of the first interference information is the second format.
[0210] For example, the format of the first interference information comprises an interference value when the format of the first interference information is the second format, but does not comprise a confidence level.
[0211] For example, the confidence level can be replaced by a probability, an accuracy, an uncertainty, an uncertainty range, a soft value, or the like, which is characterized by that the greater the value is, the higher the probability of occurrence is, or the greater the confidence level or credibility is, or the higher the accuracy is, or the lower the uncertainty is, or the smaller the uncertainty range is. For example, the confidence level can be a value between 0 and 1, for example, can be a value between 0 and 1 with a granularity of 0.1. For example, the value range of the confidence level is {0, 0.1, 0.2, …, 1}.
[0212] In this embodiment, by introducing the first format and the second format, the network side device can determine the format of the first interference information reported by the terminal according to the implementation algorithm based on interference coordination, the terminal capability, and the consideration of reporting overhead, to ensure the accuracy of the first interference information and improve the performance of network side interference coordination. For example, when the terminal reports multiple interference values and their confidence levels, the network side device can determine an interference coordination strategy based on the interference value with the highest confidence level, or determine an interference coordination strategy by comprehensively considering all possible interference values, to increase the flexibility and throughput of network implementation.
[0213] In some embodiments, when the format of the first interference information is the first format, the first configuration information further comprises eleventh indication information, and the eleventh indication information is used to indicate a granularity of the confidence level.
[0214] For example, the granularity of the confidence level can be a value between 0 and 1, for example, can be 0.1.
[0215] Since the granularity of the confidence level is too large, the accuracy thereof will be reduced, and the granularity of the confidence level is too small, the reporting overhead of the first interference information will be increased. In this embodiment, by introducing the eleventh indication information, the network side device can flexibly control the accuracy and reporting overhead of the first interference information, for example, which is helpful to balance the accuracy and reporting overhead of the first interference information.
[0216] In some embodiments, the first configuration information further comprises twelfth indication information, the twelfth indication information being used for indicating a number of interference values included in one interference instance, or the twelfth indication information being used for indicating a number of confidence levels included in one interference instance; wherein the one interference instance is associated with at least one of the following:
[0217] one time domain resource unit associated with the reported interference information;
[0218] one frequency domain resource unit associated with the reported interference information;
[0219] one cell identity associated with the reported interference information;
[0220] one reference signal identity associated with the reported interference information;
[0221] one reference signal resource identity associated with the reported interference information;
[0222] one reference signal resource set identity associated with the reported interference information;
[0223] one reference signal resource indication associated with the reported interference information;
[0224] one reference signal configuration identity associated with the reported interference information;
[0225] one transmission reception point (TRP) identity associated with the reported interference information;
[0226] one port identity associated with the reported interference information.
[0227] For example, for the ith time slot, the jth sub-band, and the s-th reference signal resource, they can be associated with the same interference instance, and the terminal can determine a plurality of possible interference values for the interference instance.
[0228] Exemplarily, when the first interference information is in the first format, the twelfth indication information is used for indicating the number of confidence levels included in the one interference instance. Optionally, the number of interference values included in the one interference instance is equal to the number of confidence levels included in the one interference instance. Alternatively, the twelfth indication information is used for indicating a first value, and both the number of confidence levels included in the one interference instance and the number of interference values included in the one interference instance are the first value. Optionally, when the first interference information is in the first format, there is a one-to-one correspondence between the interference values included in the one interference instance and the confidence levels included in the one interference instance, for example, the ith interference value corresponds to the ith confidence level.
[0229] Exemplarily, when the first interference information is in the first format or the second format, the twelfth indication information is used to indicate the number of interference values included in the one interference instance. For example, when the first interference information is in the first format, the number of interference values included in the one interference instance is equal to the number of confidence levels included in the one interference instance. Alternatively, the twelfth indication information is used to indicate a first value, and both the number of confidence levels and the number of interference values included in the one interference instance are the first value. Optionally, when the first interference information is in the first format, there is a one-to-one correspondence between the interference values and the confidence levels included in the one interference instance, for example, the ith interference value corresponds to the ith confidence level. For another example, when the first interference information is in the second format, the twelfth indication information is used to indicate the number of interference values included in the one interference instance, and the interference values included in the one interference instance include the interference values selected in the one interference instance in descending order of confidence levels.
[0230] For example, the twelfth indication information is used to indicate that one interference instance includes K interference values in descending order of confidence levels. For example, when K is equal to 2, if the one interference instance can include the following information: -20dBm, 1 / 3, -18dbm, 1 / 6, -20dBm and 1 / 3 represent the confidence level of the interference value -20dBm on the resource associated with the one interference instance is 1 / 3, -18dBm and 1 / 6 represent the confidence level of the interference value -18dBm on the resource associated with the one interference instance is 1 / 6. For another example, one interference instance is represented as P(IpN=x k |t=t m ,f=f n ,s=s q ), it represents that the confidence level of the interference value x m in the interference instance associated with the time domain resource unit t n , the frequency domain resource unit f n and q k is P, and q n represents at least one of the following: cell identification, reference signal identification, reference signal resource identification, reference signal resource set identification, reference signal resource indication, reference signal configuration identification, identification of a TRP, port identification.
[0231] It should be understood that for one interference instance, when the first device predicts the interference value on the resource associated with the one interference instance, the prediction result can include a plurality of confidence levels, the plurality of confidence levels correspond to a plurality of values one by one, and one of the plurality of confidence levels can be used to represent the probability that the interference value on the resource associated with the one interference instance is the value corresponding to the confidence level.
[0232] In this embodiment, by introducing the twelfth indication information, the first device can report one or more interference values (and one or more confidence levels) for one interference instance, for example, for the information (such as a reference signal resource, a time interval, or a frequency interval) associated with one interference instance, the first device can report a plurality of possible interference values (and one or more confidence levels), which not only enriches the reporting format of the first interference information, but also enables the format of the first interference information to be as consistent as possible with the format of the predicted output information, thereby improving the accuracy of the first interference information.
[0233] In some embodiments, the reporting quantity includes a type of the first interference information, and the type of the first interference information includes at least one of the following:
[0234] interference power;
[0235] Signal to Interference plus Noise Ratio (SINR);
[0236] interference level.
[0237] Exemplarily, the first interference information can be reported together with other CSI, for example, at least one of the following:
[0238] CSI-RS Resource Indicator (CRI) interference plus power, for example, CRI-Interference plus Noise (CRI-IpN);
[0239] CRI-SINR;
[0240] CRI interference level (CRI-Interference level);
[0241] SSB index interference plus power (SSB-index-Interference plus power), for example, CRI-IpN;
[0242] SSB index (SINR SSB-index--SINR);
[0243] SSB index interference level (SSB-index--Interference level).
[0244] It should be noted that in the NR protocol, the terminal only supports reporting of SINR, and does not support reporting of other types of interference information. In this embodiment, the reporting quantity includes the type of the first interference information, which means that the second device can flexibly instruct the type of interference information reported by the first device based on actual needs, or can instruct different capability terminals to report the type of information they support, thereby reducing the complexity of the first device in acquiring the first interference information.
[0245] Moreover, since the SINR value is affected by the target cell signal power, it cannot accurately reflect the interference information. For example, the network side device cannot determine whether a low SINR value is caused by a low target cell signal power or a high interference power, and therefore cannot perform interference coordination based on the interference information. In this embodiment, the network indication reporting quantity includes the type of the first interference information, so that the terminal can directly report a specific type of interference information, and thus the network side device can perform interference coordination based on the interference information, thereby improving the throughput of the system and the service experience of the user.
[0246] In some embodiments, the method 200 further includes:

For example, the time domain reporting configuration includes one or more indication information of time domain resources, including that the time domain reporting configuration includes the third indication information described above.
[0253] Exemplarily, the frequency domain reporting configuration comprises one or more indication information of frequency domain resource, including: the frequency domain reporting configuration comprises at least one of the sixth indication information to the tenth indication information involved above. For example, the frequency domain reporting configuration comprises one or more indication information of frequency domain resource, including: the frequency domain reporting configuration comprises the eighth indication information involved above.
[0254] Exemplarily, if the reporting quantity indicates that the type of the interference information reported by the first device is the type of interference information, and the time domain reporting configuration comprises one or more indication information of time domain resource, the first device predicts the first interference information and reports the first interference information. Or, if the reporting quantity indicates that the type of the interference information reported by the first device is the type of interference information, and the frequency domain reporting configuration comprises one or more indication information of frequency domain resource, the first device predicts the first interference information and reports the first interference information.

Optionally, the type of interference information can be the type involved above, which is not limited in the present application.
[0255] In the embodiment, by introducing the first condition, it is equivalent to indicate whether the first device reports the first interference information by an implicit indication manner, and the signaling overhead of interference information reporting can be reduced.
[0256] In some embodiments, before the first device reports the first interference information, the method 200 further comprises:

[0271] a reference signal resource indication;
[0272] a reference signal configuration identifier;
[0273] an identifier of a transmission and reception point (TRP);
[0274] a port identifier.
[0275] For example, assuming that the format of the first interference information is the second format described above, one interference instance is associated with one time domain resource unit and one frequency domain resource unit, and one interference instance includes one interference value, for a certain reference signal resource, the first interference information includes MxN interference values predicted for M time domain resource units configured by the time domain reporting configuration described above and N frequency domain resource units configured by the frequency domain reporting configuration, that is, MxN interference values, and the first device can arrange the MxN interference values in any of the following ways to obtain the first interference information:
[0276] Method 1:
[0277] arrange the MxN interference values in the order of frequency domain first and then time domain, for example, the first N interference values are the interference values of N frequency domain resource units in the first time domain resource unit of the M time domain resource units, and N+1~2xN are the interference values of N frequency domain resource units in the second time domain resource unit of the M time domain resource units. The interference values of N frequency domain resource units in any one of the M time domain resource units can be arranged in ascending order or descending order of the frequency domain.
[0278] Method 2:
[0279] The M*N interference values are arranged in a time domain first and then frequency domain manner, such as the first M interference values are of M time domain resource units in a first frequency domain resource unit of N frequency domain resource units, and the M+1~2*M interference values are of M time domain resource units in a second frequency domain resource unit of N frequency domain resource units. The interference values of the M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order or descending order of frequency domain.
[0280] For example, assuming that the format of the first interference information is the second format described above, one interference instance is associated with one time domain resource unit and one frequency domain resource unit, and one interference instance includes K interference values selected in descending order of confidence, for a certain reference signal resource, the first interference information includes predicted interference values of M*N time-frequency domain resource units formed by M time domain resource units configured by the time domain reporting configuration described above and N frequency domain resource units configured by the frequency domain reporting configuration, i.e. K*M*N interference values, the first device can arrange the K*M*N interference values in any of the following ways to obtain the first interference information:

The interference values of the M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order or descending order of frequency domain.
[0283] Method 2:
[0284] According to the sorting sequence number of the confidence, for the MxN interference values with the first highest confidence, the first device can arrange the MxN interference values in the time domain first and then in the frequency domain, such as the first M interference values are the interference values of the M time domain resource units in the first frequency domain resource unit of the N frequency domain resource units; the M+1~2M interference values are the interference values of the M time domain resource units in the second frequency domain resource unit of the N frequency domain resource units. For the MxN interference values with the second highest confidence, the first device can arrange the MxN interference values with the second highest confidence in the time domain first and then in the frequency domain, such as the first M interference values are the interference values of the M time domain resource units in the first frequency domain resource unit of the N frequency domain resource units; the M+1~2M interference values are the interference values of the M time domain resource units in the second frequency domain resource unit of the N frequency domain resource units. Similarly, the sorting of the MxN interference values with the Kth highest confidence is completed. The interference values of the M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order or descending order of the frequency domain.
[0285] In some embodiments, the first interference information comprises at least one of:
[0286] an interference value;
[0287] a confidence of the interference value;
[0288] a time domain resource associated with the interference value;

[0294] Exemplarily, the time domain resource associated with the interference value can comprise one or more time domain resource units. The time domain resource associated with the interference value can be indicated by an index of the time domain resource associated with the interference value, or the time domain resource associated with the interference value can be indicated by a third offset value, which can be an offset value of the time domain resource associated with the interference value relative to the first time domain resource unit of the frame in which the time domain resource is located, the first time domain resource unit of the measurement window, the first time domain resource unit of the prediction window, or the reference time mentioned above.

For example, the interference value in the first interference information can be associated with a reference signal group identifier, and the reference signal associated with the reference signal group identifier includes at least one reference signal.
[0298] The embodiments provided in the present application are described below in conjunction with the accompanying drawings.
[0299] Embodiment 1:
[0300] In this embodiment, the network side device performs inter-cell interference coordination by predicted interference information, which has better timeliness.
[0301] The interference received by the terminal can be caused by multiple interference sources, such as neighboring base stations, sidelink communication between other UEs, other UEs, etc. The interference received by the UE, which can also be referred to as interference-plus-noise (IpN), can rapidly change in the time domain, frequency domain, and spatial domain. IpN refers to the sum of the interference power and the noise power measured by the UE, and in this case, the interference also includes the interference power or the interference-plus-noise power. The interference received by the terminal has correlation in the time domain, frequency domain, and spatial domain, such as the change of the interference in the time domain, which can be related to the interference in the frequency domain or spatial domain, and the future interference can be related to the past interference. Based on this, as shown in FIG. 5, future interference information can be predicted based on historical measured interference information using an AI model.
[0302] In one aspect, the interference prediction can be performed at the terminal side, i.e., the terminal can predict the future interference information on the second communication resource based on the past interference measurement on the first communication resource. Then, the terminal can report the predicted interference information to the network side, or optimize the parameters of the receiver related algorithm based on the predicted interference information, etc.
[0303] For example, as shown in FIG. 6, after the terminal reports the capability information to the network side device, the terminal receives the configuration information (e.g., the first configuration information as mentioned above), and then performs the interference prediction and the interference reporting (e.g., reports the first interference information as mentioned above) as described, so that the network side device sends the scheduling information to the terminal based on the reported interference information.
[0304] On the other hand, the interference prediction can be performed at the network side, i.e., the terminal reports the interference measurement of the first communication resource to the network side. Then, the network side predicts the future interference information of the terminal on the second communication resource based on the interference measurement reported by the terminal, and further determines the air interface resource allocated to the UE for data transmission or signaling transmission based on the information. The first communication resource and the second communication resource can be the same, partially the same or different, which is not limited herein. The communication resource as described in the present case can be regarded as a collection of one or more of the time domain resource, the frequency domain resource and the space domain resource, and can also be associated with at least one reference signal resource, at least one reference signal resource set or at least one reference signal configuration.
[0305] For example, as shown in FIG. 7, after the terminal reports the capability information to the network side device, the terminal receives the configuration information (e.g., the first configuration information as mentioned above), and then performs the interference measurement and the interference reporting (e.g., reports the first interference information as mentioned above) as described, so that the network side device performs the interference prediction based on the reported interference information, and sends the scheduling information to the terminal based on the predicted interference information.
[0306] The terminal can measure interference through an interference measurement resource, which refers to a communication resource configured by the base station for the UE to measure interference, such as a channel state information reference signal (CSI-RS) channel state information for interference measurement (CSI-IM), or through an interference measurement resource (IMR). A CSI-RS refers to a reference signal transmitted by the base station, which can be used by the terminal to estimate a channel and feed back channel state information to the base station or network node (hereinafter collectively referred to as a base station, which also includes a base station or other access network network node). A CSI-IM refers to a set of resource elements (REs) reserved for interference measurement. An IMR is a time-frequency resource allocated by the network to the UE for measuring interference. The interference measured by the terminal can be reported to the base station through channel state feedback (CSF) reporting. In related technologies, a CSF report does not include specific time, frequency, or spatial domain resource-related interference information. Interference-related information includes but is not limited to: interference power, signal to interference plus noise ratio (SINR), power level, carrier to interference ratio (C / I), and the like measured or predicted on a certain time domain, frequency domain, or spatial domain resource. Interference level is an index describing the intensity of interference. In one case, the interference level can be divided into three levels: high, medium, and low, and in this case, 2 bits can be used to indicate the current interference intensity. In one case, the interference level can be divided into ten levels, for example, 1-10, and the larger the value, the greater the intensity of interference. Each level identifier can be associated with a range of interference power or SINR, which can depend on device implementation or protocol agreement. It should be understood that the interference-related information involved in the present application includes interference values and information associated or related to the interference values.
[0307] Since the base station does not know the interference suffered by the target UE on the target communication resource, the base station can also not be able to schedule communication resources for the UE based on the CSF report using interference-related information. At this time, the serving base station can configure or schedule communication resources with relatively high interference intensity for the UE, which can reduce the SINR of the signal and further degrade communication performance, such as increased block error rate of data transmission, increased latency, and the like.
[0308] In order to enable the base station (including serving base station or neighbor base station) to consider the time, frequency and spatial correlation characteristics of the interference suffered by the terminal side when scheduling resources, the terminal needs to report interference-related information to the base station. Among them, the interference-related information can obtain a set of (including one or more) measured or predicted interference values (such as interference power or SINR), or a set of (including one or more) measured or predicted interference values and their corresponding probabilities through at least one interference measurement instance, wherein the at least one interference measurement instance can be obtained by the UE on a set of interference measurement resources in the time domain, frequency domain or spatial domain, which can include one or more CSI-RS, one or more CSI-IM, or one or more IMR. The measured interference value refers to the interference value obtained by at least one interference measurement instance. The predicted interference value refers to the future interference value predicted based on at least one past interference measurement instance.
[0309] The form of the reported interference-related information can be a distribution-based representation or a non-distribution-based representation. Among them, for the distribution-based representation, the interference distribution reported by the terminal can be a probability density function (Probability density function) related to the time domain, frequency domain or spatial domain, or a probability mass function (Probability mass function). A probability density function describes the probability of a continuous random variable within a range. A probability mass function describes the probability that a discrete random variable is equal to a certain value. For example, X is a discrete random variable, and its possible value range is: X = {x1, x2, x3, x4…}.
[0310] The probability mass function of X is: X (x k ) = P(X = x k ), k = 1, 2, 3, 4…
[0311] In an embodiment: the form of the reported interference distribution is the probability mass function, which describes the measured or predicted interference value and its probability on a certain time domain, frequency domain or spatial domain resource, that is: k | t = t m , f = f n , s = s q ); k = 1, 2, 3, 4…; m = 1, 2, 3, 4…; n = 1, 2, 3, 4…; q = 1, 2, 3, 4…
[0312] Where x k represents the kth interference power, such as x1 = -30 dBm, x2 = -31 dBm, x3 = -32 dBm, ….
[0313] t m denotes the mth time domain resource, such as t1 = slot1, t2 = slot2, t3 = slot3, ….
[0314] f n denotes the nth frequency domain resource, such as f1 = subband1, f2 = subband2, f3 = subband3, ….
[0315] q n denotes the nth spatial domain resource, such as s1 = beamindex1, s2 = beamindex2, s3 = beamindex3, ….
[0316] In this embodiment, P(IpN = x k |t = t m , f = f n , s = s q ) describes: the probability that the terminal measures or predicts the interference power as x n on the time domain resource t n , the frequency domain resource f m , and the spatial domain resource q k .
[0317] Of course, the granularity of the time domain resource, the frequency domain resource, and the spatial domain resource can also be other, such as the time domain resource can also be an OFDM symbol, a slot, a subframe, a frame, etc., the frequency domain resource can also be a physical resource block (Physical resource block, PRB) or a resource block (Resource block, RB), a subband, a subband group, or the entire bandwidth, and the spatial domain resource can also be a physical cell, a reference signal resource, a port, a TRP, an SSB, etc. One time domain resource described in the present case can be one OFDM symbol, one slot, one subframe, or one frame; one frequency domain resource described in the present case can be one physical resource block (Physical resource block, PRB) or one resource block (Resource block, RB), one subband, one subband group, or the entire bandwidth; and one spatial domain resource described in the present case can be one physical cell, one reference signal resource, one port, one TRP, one SSB, or a combination of multiple physical cells, a reference signal resource group, a port group, multiple TRPs, or a combination of multiple SSB indexes.
[0318] The probability described in the present application can also be replaced by confidence, accuracy, uncertainty, uncertainty range, etc. The characteristic is that the larger the value, the higher the probability of occurrence, or the greater the confidence or reliability, or the higher the accuracy, or the lower the uncertainty, or the smaller the uncertainty range.
[0319] The base station can configure the granularity of the interference measurement or prediction:
[0320] Frequency domain granularity: the interference measurement or prediction is based on full bandwidth or sub-band (or multiple sub-bands), etc., such as one interference value can be associated with full bandwidth or (one or multiple) sub-band, then this interference value describes the interference strength of full bandwidth or (one or multiple) sub-band;
[0321] Time domain granularity: the interference measurement or prediction is symbol level interference, time slot level interference, or multiple time slot level interference, etc., such as one interference value is time slot level interference, then this interference value describes the interference strength of 1 time slot;
[0322] Spatial domain granularity: the base station can configure multiple reference signal resources or beams for the interference measurement or prediction, such as one interference value is associated with 1 specific beam or reference signal resource, then this interference value describes the interference strength of the beam or reference signal resource.
[0323] Embodiment 2:
[0324] In this embodiment, the terminal reports the interference information predicted for the time interval within the prediction window.
[0325] The terminal receives the time domain reporting configuration sent by the network side device, and the time domain reporting configuration is used to configure the position of the prediction window in the time domain. After receiving the time domain reporting configuration, the terminal predicts and reports the interference information (for example, the first interference information mentioned above) based on the time domain reporting configuration, which includes the interference value on the time interval within the prediction window. Optionally, the time domain reporting configuration includes at least one of the following: first indication information, second indication information, third indication information, fourth indication information, and fifth indication information. The first indication information is used to indicate the time domain resource unit included in the prediction window. Optionally, the second indication information is used to indicate the time domain starting time of the prediction window. Optionally, the third indication information is used to indicate the time length of the prediction window. Optionally, the fourth indication information is used to indicate the reference time of the prediction window. Optionally, the fifth indication information is used to indicate the time length of the time interval within the prediction window.
[0326] For example, as shown in FIG. 8, the second indication information includes or is used to indicate a first offset value, for example, the first offset value is the offset value of the time domain starting time of the prediction window relative to the reference time. The third indication information indicates that the prediction window includes 8 time intervals. The reference time indicated by the fourth indication information is located before the time window. The time length indicated by the fifth indication information indicates the duration length of the interval between the two reported interference values in the time domain. It should be understood that the description of the first indication information to the fifth indication information and related terms can refer to the related content mentioned above, and to avoid repetition, it will not be described again this time.
[0327] Embodiment 3
[0328] In this embodiment, the terminal reports the interference information predicted for the frequency domain interval within a subband, a wideband, or a prediction window.
[0329] In one implementation, the terminal reports the interference information predicted for a subband or a wideband.
[0330] In one case, the reporting of the predicted interference value, the network can indicate an interference power format indicator (InterferencePower-FormatIndicator) to indicate that the format of the interference information is {wideband interference power, subband interference power}, and if the subband interference power is reported, the network indicates through a bitmap in the CSI-reportingBand which subbands the interference values are reported for. In another case, since the interference information is mainly used for interference coordination, it can not be necessary to report an interference value for each subband, and in one possible implementation, the network can indicate that every N subbands are bundled together, such as every N subbands being considered as a frequency domain interval or a frequency domain resource unit, and one interference value is reported for every N subbands that are bundled together to reduce the reporting overhead. The bundling granularity can be related to the frequency domain granularity of the scheduling of the interfering cell, and the network can determine the frequency domain granularity according to the requirements, in combination with the requirements of the interference coordination strategy and taking into account the reporting overhead. For example, as shown in FIG. 9, subband 1 and subband 2 are bundled into subband group 1, and subband 2 and subband 3 are bundled into subband group 2. One subband group is associated with one interference measurement value or predicted value. In another possible implementation, the network configures a subband size (subbandSize) for the reported interference information, but can extend the number of PRBs included in the subband size.
[0331] For example, the configured subband size can be extended to the subband sizes shown in the following table:
[0332] Table 1
[0333] For example, as shown in Table 1, when the BWP includes 73-144 PRBs, the subband size can be extended to support a larger granularity of 32 PRBs in one subband, and so on.
[0334] In another implementation, the terminal reports the interference information predicted for the frequency domain interval within a prediction window.
[0335] The terminal receives a frequency domain reporting configuration sent by the network side device, and the frequency domain reporting configuration is used to configure a position of the prediction window in the frequency domain. After receiving the frequency domain reporting configuration, the terminal predicts and reports the interference information (for example, the first interference information mentioned above) based on the frequency domain reporting configuration, which includes interference values on the frequency domain intervals in the prediction window. Optionally, the frequency domain reporting configuration includes at least one of the sixth indication information, the seventh indication information, the eighth indication information, the ninth indication information, and the tenth indication information. The sixth indication information is used to indicate the frequency domain resource units included in the prediction window. The seventh indication information is used to indicate a frequency domain start time of the prediction window. The eighth indication information is used to indicate a frequency domain length of the prediction window. The ninth indication information is used to indicate a reference frequency domain position of the prediction window. The tenth indication information is used to indicate a length of the frequency domain interval in the prediction window.
[0336] For example, as shown in FIG. 10, the sixth indication information indicates that the prediction window can include subband 10 to subband 13. The seventh indication information includes or is used to indicate a second offset value, for example, the second offset value is an offset value of the frequency domain start of the prediction window relative to the reference frequency domain position. The eighth indication information indicates that the prediction window includes 4 subbands. The ninth indication information indicates that the reference frequency domain position is the start position of subband 0. The tenth indication information indicates that the length of the frequency domain interval is one subband. It should be understood that the sixth indication information to the tenth indication information and the description of related terms can refer to the related content mentioned above, and to avoid repetition, this time will not be repeated.
[0337] In a specific implementation, the network side device can implicitly indicate the terminal to report the interference information on certain subbands through CSI reporting band (CSI-reportingBand), for example, the terminal can be indicated to report the interference information on continuous subbands, and for another example, the terminal can be indicated to report the interference information on continuous or discontinuous subbands. Further, if the CSI reporting band indicates that the terminal reports the interference power on certain subbands in which no reference signal for interference measurement is configured, the terminal can obtain the interference information on the subbands through prediction or interpolation, such as the network side device configures the reference signal for interference measurement in subbands 1 to 10, but indicates the terminal to report the interference power on subbands 11 to 15 in the network CSI-reportingBand, in this case, the terminal can predict the interference power on subbands 11 to 15 based on the interference power on subbands 1 to 10 and report to the network side device.
[0338] Embodiment 4
[0339] In this embodiment, the terminal reports the interference information on the measurement set and / or the prediction set.
[0340] The network-side device configures a measurement set (or referred to as a first set, a measurement pattern or a first pattern) and / or a prediction set (or referred to as a second set, a prediction pattern or a second pattern), both of which are a set of reference signal resources or information associated with the set of reference signal resources. In a specific implementation, the terminal can report interference information measured on the measurement set, or the terminal can predict interference information on the prediction set based on interference information measured on the measurement set, and report the predicted interference information. The measurement set and / or the prediction set include at least one of the following: a cell identifier, a reference signal identifier, a reference signal configuration identifier, a transmission and reception point (TRP) identifier, and a port identifier.
[0341] For example, as shown in FIG. 11, the measurement set includes reference signal resources associated with SSB indexes 1-3, and the prediction set includes reference signal resources associated with SSB indexes 4-5; the terminal can predict interference power on the reference signal resources associated with SSB indexes 4-5 based on interference power measured on the reference signal resources associated with SSB indexes 1-3.
[0342] Of course, in other alternative embodiments, the terminal can predict interference power on reference signal resources associated with cell identifiers 4-5 based on interference power measured on reference signal resources associated with cell identifiers 1-3, or the terminal can predict interference power on reference signal resources associated with reference signal resource identifiers 4-5 based on interference power measured on reference signal resources associated with reference signal resource identifiers 1-3, or the terminal can predict interference power on reference signal resources associated with TRPs 4-5 based on interference power measured on reference signal resources associated with TRPs 1-3, or the terminal can predict interference power on reference signal resources associated with port identifiers 4-5 based on interference power measured on reference signal resources associated with port identifiers 1-3. The present application does not make specific limitations in this regard.
[0343] Embodiment 5
[0344] This embodiment describes interference information reported by the terminal (e.g., the first interference information described above).
[0345] The interference information reported by the terminal can include at least one of the following:
[0346] The terminal can report at least one of the following:
[0347] interference instance; wherein the interference instance comprises at least one of: at least one interference value, at least one interference value and at least one confidence degree corresponding to the at least one interference value. For example, if the one interference instance can comprise the following information: -20dBm, 1 / 3, -18dbm, 1 / 6, -20dBm and 1 / 3 indicate that the confidence degree of the interference value being -20dBm on the resource associated with the one interference instance is 1 / 3, -18dBm and 1 / 6 indicate that the confidence degree of the interference value being -18dBm on the resource associated with the one interference instance is 1 / 6. For another example, one interference instance is expressed as P(IpN=x k |t=t m ,f=f n ,s=s q ), it indicates that the terminal includes the interference value x m in the interference instance associated with the time domain resource t n , the frequency domain resource f n and q k , and the confidence degree is P. q n indicates at least one of: cell identity, reference signal identity, reference signal resource identity, reference signal resource set identity, reference signal resource indication, reference signal configuration identity, identity of TRP, port identity.
[0348] For example, as shown in FIG. 12, one interference instance can be associated with 1 frequency domain resource unit, 1 time domain resource unit and other information, and the other information comprises at least one of: 1 cell identity, 1 reference signal identity, 1 reference signal resource identity, 1 reference signal resource set identity, 1 reference signal resource indication, 1 reference signal configuration identity, 1 identity of TRP, 1 port identity. One interference instance can comprise one or more predicted interference values and one or more confidence degrees, and the one or more predicted interference values and the one or more confidence degrees are in one-to-one correspondence.
[0349] Time domain resource associated with the interference value; for example, the time domain resource associated with the interference value can be a certain time domain resource unit t m . The time domain resource associated with the interference value can be indicated by the index of the time domain resource associated with the interference value, or the index of the time domain resource associated with the interference value can be indicated by an offset value relative to the first time domain resource unit of the frame or the first time interval of the prediction window.
[0350] Frequency domain resource associated with the interference value; for example, the frequency domain resource associated with the interference value can be a certain frequency domain resource unit f nThe frequency domain resource associated with the interference value can be indicated by an index of the frequency domain resource associated with the interference value, or the index of the frequency domain resource associated with the interference value can be indicated by an offset value relative to the first frequency domain resource unit or the first time interval of a prediction window of a first frame in which the index is located.
[0351] The interference value is associated with at least one of the following: a cell identifier, a reference signal identifier, a reference signal resource identifier, a reference signal resource set identifier, a reference signal resource indication, a reference signal configuration identifier, a transmission and reception point (TRP) identifier, and a port identifier; for example, the reference signal resource associated with the reference signal identifier, the reference signal resource identifier, the reference signal resource set identifier, the reference signal resource indication, or the reference signal configuration identifier can be a CSI-RS reference resource. Of course, a reference signal group configuration identifier associated with the interference value can also be included, and the reference signal group associated with the reference signal group configuration identifier includes at least one reference signal for interference measurement.
[0352] In some embodiments, the predicted interference value or the confidence level needs to be sorted before the terminal reports the interference information.
[0353] Assuming that the interference instance does not include the confidence level, one interference instance is associated with one time domain resource unit and one frequency domain resource unit, and one interference instance includes one interference value, and for a certain reference signal resource, the interference information includes MxN interference values predicted for M time domain resource units configured by the time domain reporting configuration and N frequency domain resource units configured by the frequency domain reporting configuration, and the first device can arrange the MxN interference values in any of the following ways to obtain the interference information:
[0354] Method 1:
[0355] The MxN interference values are arranged in the order of frequency domain first and time domain second, such as the first N interference values are for N frequency domain resource units in the first time domain resource unit of the M time domain resource units, and N+1~2xN are for N frequency domain resource units in the second time domain resource unit of the M time domain resource units. Among them, the N interference values of the N frequency domain resource units in any one of the M time domain resource units can be arranged in ascending order or descending order according to the index of the frequency domain.
[0356] For example, as shown in FIG. 13, assuming that the interference information includes 2x2 interference values associated with 2x2 time-frequency domain resource units, in this case, when the interference values of M time domain resource units in any one of the N frequency domain resource units are arranged in ascending order of frequency domain, the arrangement order of the predicted interference values is: the interference value associated with time-frequency domain resource unit 1, the interference value associated with time-frequency domain resource unit 3, the interference value associated with time-frequency domain resource unit 2, and the interference value associated with time-frequency domain resource unit 4.
[0357] Mode 2:
[0358] The MxN interference values are arranged in the time domain first and then in the frequency domain, for example, the first M of them are the interference values of M time domain resource units in the first frequency domain resource unit of N frequency domain resource units, and the M+1-2xM of them are the interference values of M time domain resource units in the second frequency domain resource unit of N frequency domain resource units. Among them, the interference values of M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order or descending order of frequency domain.
[0359] For example, as shown in FIG. 13, assuming that the interference information includes 2x2 interference values associated with 2x2 time-frequency domain resource units, in this case, when the interference values of M time domain resource units in any one of the N frequency domain resource units are arranged in ascending order of frequency domain, the arrangement order of the predicted interference values is: the interference value associated with time-frequency domain resource unit 1, the interference value associated with time-frequency domain resource unit 2, the interference value associated with time-frequency domain resource unit 3, and the interference value associated with time-frequency domain resource unit 4.
[0360] Assuming that the interference instance does not include a confidence level, one interference instance is associated with one time domain resource unit and one frequency domain resource unit, and one interference instance includes K interference values, for a certain reference signal resource, the interference information includes KxMxN interference values associated with MxN time-frequency domain resource units formed by M time domain resource units configured by the time domain reporting configuration and N frequency domain resource units configured by the frequency domain reporting configuration, the first device can arrange the KxMxN interference values in the following any one way to obtain the interference information:
[0361] Mode 1:
[0362] According to the sorting sequence number of the confidence, for the MxN interference values with the first highest confidence, the first device can arrange the MxN interference values with the first highest confidence in the order of frequency domain first and time domain second, such as the first N interference values of N frequency domain resource units in a first time domain resource unit of the M time domain resource units, and the N+1th to 2xNth interference values of N frequency domain resource units in a second time domain resource unit of the M time domain resource units. For the MxN interference values with the second highest confidence, the first device can arrange the MxN interference values with the second highest confidence in the order of frequency domain first and time domain second, such as the first N interference values of N frequency domain resource units in a first time domain resource unit of the M time domain resource units, and the N+1th to 2xNth interference values of N frequency domain resource units in a second time domain resource unit of the M time domain resource units. Similarly, the sorting of the MxN interference values with the Kth highest confidence is completed. The interference values of N frequency domain resource units in any one of the M time domain resource units can be arranged in the order of frequency domain from small to large or from large to small.
[0363] For example, as shown in FIG. 13, assuming that K=2, the interference information includes 2x2 time-frequency domain resource unit associated interference values, i.e., 2x2x2 interference values, and the interference values of N frequency domain resource units in any one of the M time domain resource units can be arranged in the order of frequency domain from small to large. In this case, the arrangement order of the predicted interference values is: the interference value with the first highest confidence associated with time-frequency domain resource unit 1, the interference value with the first highest confidence associated with time-frequency domain resource unit 3, the interference value with the first highest confidence associated with time-frequency domain resource unit 2, the interference value with the first highest confidence associated with time-frequency domain resource unit 4, the interference value with the second highest confidence associated with time-frequency domain resource unit 1, the interference value with the second highest confidence associated with time-frequency domain resource unit 3, the interference value with the second highest confidence associated with time-frequency domain resource unit 2, and the interference value with the second highest confidence associated with time-frequency domain resource unit 4.
[0364] Method 2:
[0365] According to the sorting sequence of the confidence, for the MxN interference values with the first highest confidence, the first device can arrange the MxN interference values in a time domain first and then a frequency domain, such as the first M interference values are the interference values of the M time domain resource units in the first frequency domain resource unit of the N frequency domain resource units, and the M+1-2xM interference values are the interference values of the M time domain resource units in the second frequency domain resource unit of the N frequency domain resource units. For the MxN interference values with the second highest confidence, the first device can arrange the MxN interference values with the second highest confidence in a time domain first and then a frequency domain, such as the first M interference values are the interference values of the M time domain resource units in the first frequency domain resource unit of the N frequency domain resource units, and the M+1-2xM interference values are the interference values of the M time domain resource units in the second frequency domain resource unit of the N frequency domain resource units. Similarly, the arrangement of the interference values with the Kth highest confidence is completed. The interference values of the M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order or descending order of the frequency domain.
[0366] For example, as shown in FIG. 13, assuming that K=2, the interference information includes 2x2 time-frequency domain resource unit associated interference values, i.e., 2x2x2 interference values, and the interference values of the M time domain resource units in any one of the N frequency domain resource units can be arranged in ascending order of the frequency domain, and the arrangement order of the predicted interference values is: the interference value with the first highest confidence associated with the time-frequency domain resource unit 1, the interference value with the first highest confidence associated with the time-frequency domain resource unit 2, the interference value with the first highest confidence associated with the time-frequency domain resource unit 3, the interference value with the first highest confidence associated with the time-frequency domain resource unit 4, the interference value with the second highest confidence associated with the time-frequency domain resource unit 1, the interference value with the second highest confidence associated with the time-frequency domain resource unit 2, the interference value with the second highest confidence associated with the time-frequency domain resource unit 3, and the interference value with the second highest confidence associated with the time-frequency domain resource unit 4.
[0367] Of course, in other alternative embodiments, the predicted interference values are not grouped, and the KxMxN interference values can be arranged in any of the following manners to obtain the interference information:
[0368] Method 3:
[0369] The K*M*N interference values are arranged in the order of time domain first and frequency domain second, such as the first K interference values are the interference values included in the first interference instance, the first+1~2*K interference values are the interference values included in the second interference instance, and so on, until the sorting of the K*M*N interference values is completed. Wherein, one interference instance is associated with one time domain resource unit in the M time domain resource units and one frequency domain resource unit in the N frequency domain resource units; the order of the interference instances can be determined in the order of time domain first and frequency domain second. For example, the first interference instance is associated with the interference values of the first time domain resource unit in the M time domain resource units and the first frequency domain resource unit in the N frequency domain resource units, and the second interference instance is associated with the first time domain resource unit in the M time domain resource units and the second frequency domain resource unit in the N frequency domain resource units. Wherein, the K interference values included in one interference instance can be arranged in the order of confidence from large to small.
[0370] For example, as shown in FIG. 13, assuming that K=2, the interference information includes 2*2 time-frequency domain resource unit associated interference values, i.e. 2*2*2 interference values, then in this way, the interference values of the N frequency domain resource units in any one time domain resource unit in the M time domain resource units can be arranged in the order of frequency domain from small to large. The arrangement order of the predicted interference values is: 2 interference values associated with the time-frequency domain resource unit 1, 2 interference values associated with the time-frequency domain resource unit 3, 2 interference values associated with the time-frequency domain resource unit 2, and 2 interference values associated with the time-frequency domain resource unit 4. The 2 interference values associated with each time-frequency domain resource unit can be arranged in the order of confidence from large to small.
[0371] Method 4:
[0372] The K*M*N interference values are arranged in the order of time domain first and frequency domain second, such as the first K interference values are the interference values included in the first interference instance, the first+1~2*K interference values are the interference values included in the second interference instance, and so on, until the sorting of the K*M*N interference values is completed. Wherein, one interference instance is associated with one time domain resource unit in the M time domain resource units and one frequency domain resource unit in the N frequency domain resource units; the order of the interference instances can be determined in the order of time domain first and frequency domain second. For example, the first interference instance is associated with the interference values of the first time domain resource unit in the M time domain resource units and the first frequency domain resource unit in the N frequency domain resource units, and the second interference instance is associated with the first time domain resource unit in the M time domain resource units and the second frequency domain resource unit in the N frequency domain resource units. Wherein, the K interference values included in one interference instance can be arranged in the order of confidence from large to small.
[0373] For example, as shown in FIG. 13, assuming K=2, the interference information includes 2x2 interference values associated with 2x2 time-frequency domain resource units, i.e. 2x2x2 interference values, then in this way, the interference values of N frequency domain resource units in any one of M time domain resource units can be arranged in ascending order in the frequency domain, and the arrangement order of the predicted interference values is: 2 interference values associated with time-frequency domain resource unit 1, 2 interference values associated with time-frequency domain resource unit 2, 2 interference values associated with time-frequency domain resource unit 3, 2 interference values associated with time-frequency domain resource unit 4. The 2 interference values associated with each time-frequency domain resource unit can be arranged in descending order of confidence.
[0374] In this embodiment, the predicted interference values or the confidence can be sorted by the arrangement order agreed by the protocol, and the first device (for example, a terminal) can not report the information of the index (for example, the index of the frequency domain resource unit, the index of the time domain resource unit, the confidence, etc.) corresponding to the interference value, and the second device can determine the index corresponding to the interference value based on the same arrangement order, which is beneficial to reduce the reporting overhead.

[0377] For example, if the terminal is configured with information (for example, the indication information in the first indication information to the fifth indication information mentioned above) for determining the position of the prediction window in the time domain and the information reported by the terminal is interference information, the terminal reports the predicted interference information. For example, if the CSI reporting configuration includes information (for example, the indication information in the first indication information to the fifth indication information mentioned above) for determining the position of the prediction window in the time domain and the information reported by the terminal is interference information, the terminal reports the predicted interference information.
[0378] For another example, if the terminal is configured with information (for example, the indication information in the fifth indication information to the tenth indication information mentioned above) for determining the position of the prediction window in the time domain and the information reported by the terminal is interference information, the terminal reports the predicted interference information. For example, if the CSI reporting configuration includes information (for example, the indication information in the fifth indication information to the tenth indication information mentioned above) for determining the position of the prediction window in the time domain and the information reported by the terminal is interference information, the terminal reports the predicted interference information.
[0379] For another example, if the terminal is configured with a prediction set of interference information, and the information reported by the terminal is interference information, the terminal reports the predicted interference information.
