[0001] The present disclosure relates to a terminal, a wireless communication method, and a base station in a next-generation mobile communication system.

[0002] Long Term Evolution (LTE) has been specified for the Universal Mobile Telecommunications System (UMTS) network with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified with the aim of achieving higher capacity and more advanced features than LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9).

[0015] (Channel State Information (CSI) Measurement / Reporting) This section describes CSI measurement / reporting in existing NR standards (e.g., Rel. 15-17 NR). The UE generates (also referred to as determining, calculating, estimating, measuring, etc.) CSI based on a reference signal (RS) (or a resource for the RS), and transmits (also referred to as reporting, feedback, etc.) the generated CSI to a network (e.g., a base station). The CSI may be transmitted to the base station using, for example, an uplink control channel (e.g., a Physical Uplink Control Channel (PUCCH)) or an uplink shared channel (e.g., a Physical Uplink Shared Channel (PUSCH)).

[0016] In the present disclosure, the CSI may be a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), a SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), L1-RSRP (Layer 1 Reference Signal Received Power), L1-RSRQ (Reference Signal Received Quality), L1-SINR (Signal to Interference plus Noise Ratio), L1-SNR (Signal to Noise Ratio), information on a channel matrix (or channel coefficient), information on a precoding matrix (or precoding coefficient), a Beam / Transmission Configuration Indication (BCI), a Precoding Matrix Indicator (PMI), a CSI-RS Resource Indicator (CRI), a SS / PBCH Block Resource Indicator (SSBRI), a Layer Indicator (LI), a Rank Indicator (RI), a Layer 1 Reference Signal Received Power (L1-RSRP), a Reference Signal Received Quality (L1-RSRQ), a Signal to Interference plus Noise Ratio (L1-SINR), a Signal to Noise Ratio (L1-SNR), information on a channel matrix (or channel coefficient), information on a precoding matrix (or precoding coefficient), a Beam / Transmission Configuration Indication (BCI), a Precoding Matrix Indicator (PMI), a Beam / Transmission Configuration Indicator (BCI), a Precoding Matrix Indicator (PMI ...

[0018] In the present disclosure, RS, CSI-RS, non-zero power (NZP) CSI-RS, zero power (ZP) CSI-RS, CSI interference measurement (CSI-IM), CSI-SSB, and SSB may be interchangeable. Furthermore, CSI-RS may include other reference signals.

[0019] The UE may receive configuration information regarding CSI reporting (which may be referred to as a CSI report configuration, report setting, etc.) and control the CSI reporting based on the configuration information. The report configuration information may be, for example, a Radio Resource Control (RRC) information element (IE) "CSI-ReportConfig."

[0020] The CSI reporting configuration may include at least one of the following information: - Information about the CSI resources used for CSI measurements (resource configuration ID, e.g., "CSI-ResourceConfigId"), - Information about one or more quantities (CSI parameters) of CSI to report (report quantity information, e.g., "reportQuantity"), - Report type information indicating the time domain behavior of the reporting configuration (e.g., "reportConfigType").

[0021] In the present disclosure, a CSI resource may be interchangeably referred to as a time instance, a CSI-RS opportunity / CSI-IM opportunity / SSB opportunity, a CSI-RS resource opportunity / opportunities, a CSI opportunity, an opportunity, a CSI-RS resource / CSI-IM resource / SSB resource, a time resource, a frequency resource, an antenna port (e.g., a CSI-RS port), etc. The time unit of a CSI resource may be a slot, a symbol, etc.

[0022] The information about the CSI resource may include information about the CSI resource for channel measurement, information about the CSI resource for interference measurement (NZP-CSI-RS resource), information about the CSI-IM resource for interference measurement, and the like.

[0023] The reporting quantity information may specify any one or a combination of the above CSI parameters (eg, CRI, RI, PMI, CQI, LI, L1-RSRP, etc.).

[0024] The report type information may indicate a periodic CSI (P-CSI) report, an aperiodic CSI (A-CSI) report, or a semi-persistent CSI (SP-CSI) report.

[0025] The UE performs CSI-RS / SSB / CSI-IM measurements based on the CSI resource configuration corresponding to the CSI reporting configuration (the CSI resource configuration associated with the CSI-ResourceConfigId), and derives the CSI to report based on the measurement results.

[0026] The CSI resource configuration (e.g., CSI-ResourceConfig information element) may include a csi-RS-ResourceSetList field indicating more specific CSI-RS / SSB resources, resource type information (e.g., "resourceType") indicating the time domain behavior of the resource configuration, etc.

[0027] The resource type information may indicate a P-CSI resource, an A-CSI resource, or an SP-CSI resource.

[0028] (Application of Artificial Intelligence (AI) Technology to Wireless Communications) With regard to future wireless communications technologies, the use of AI technology such as machine learning (ML) for network / device control and management is being considered.

[0029] For example, it is being considered that terminals (user terminals, user equipment (UE)) / base stations (BSs) will utilize AI technology to improve Channel State Information (CSI) feedback (e.g., reduced overhead, improved accuracy, prediction), improve beam management (e.g., improved accuracy, prediction in the time / space domain), and improve position measurement (e.g., improved position estimation / prediction).

[0030] Based on the input information, the AI ​​model may output at least one information such as an estimate, a prediction, a selected action, a classification, etc. The UE / BS may input channel state information, reference signal measurements, etc. to the AI ​​model and output highly accurate channel state information / measurements / beam selection / location, future channel state information / radio link quality, etc.

[0032] In the present disclosure, estimation, prediction, and inference may be used interchangeably. Also, in the present disclosure, estimate, predict, and infer may be used interchangeably.

[0033] In the present disclosure, an object may be, for example, an apparatus, device, etc., such as a UE or a BS. Also, in the present disclosure, an object may correspond to a program / model / entity that operates in the apparatus.

[0034] Also, in the present disclosure, an AI model may be interpreted as an object that has (performs) at least one of the following characteristics: - Generates an estimate by feeding information; - Predicts an estimate by feeding information; - Discovers features by feeding information; - Selects an action by feeding information.

[0035] Additionally, in this disclosure, an AI model may refer to a data-driven algorithm that applies AI techniques to generate a set of outputs based on a set of inputs.

[0036] In addition, in the present disclosure, the terms AI model, model, ML model, predictive analytics, predictive analysis model, tool, autoencoder, encoder, decoder, neural network model, AI algorithm, scheme, etc. may be interchangeable. The AI ​​model may be derived using at least one of regression analysis (e.g., linear regression analysis, multiple regression analysis, logistic regression analysis), support vector machine, random forest, neural network, deep learning, etc.

[0037] In this disclosure, the term "autoencoder" may be interchangeably referred to as any autoencoder, such as a stacked autoencoder, a convolutional autoencoder, etc. The encoder / decoder of this disclosure may employ a model such as a Residual Network (ResNet), a DenseNet, or a RefineNet.

[0038] Furthermore, in the present disclosure, the terms encoder, encoding, encode / encoded, modification / alteration / control by an encoder, compressing, compress / compressed, generating, generate / generated, etc. may be read interchangeably.

[0039] In addition, in the present disclosure, decoder, decoding, decode / decoded, modification / alteration / control by decoder, decompressing, decompress / decompressed, reconstructing, reconstruct / reconstructed, etc. may be read interchangeably.

[0040] In the present disclosure, a layer (of an AI model) may be interchangeably read as a layer (such as an input layer or an intermediate layer) used in the AI ​​model. The layer in the present disclosure may correspond to at least one of an input layer, an intermediate layer, an output layer, a batch normalization layer, a convolutional layer, an activation layer, a dense layer, a normalization layer, a pooling layer, an attention layer, a dropout layer, a fully connected layer, etc.

[0041] In this disclosure, methods for training an AI model may include supervised learning, unsupervised learning, reinforcement learning, federated learning, etc. Supervised learning may refer to the process of training a model from inputs and corresponding labels. Unsupervised learning may refer to the process of training a model without labeled data. Reinforcement learning may refer to the process of training a model from inputs (i.e., states) and feedback signals (i.e., rewards) resulting from the model's outputs (i.e., actions) in an environment with which the model interacts.

[0042] In the present disclosure, terms such as generate, calculate, derive, etc. may be interchangeable. In the present disclosure, terms such as implement, operate, operate, execute, etc. may be interchangeable. In the present disclosure, terms such as train, learn, update, retrain, etc. may be interchangeable. In the present disclosure, terms such as infer, after-training, live use, actual use, etc. may be interchangeable. In the present disclosure, signal may be interchangeable with signal / channel.

[0043] 1 is a diagram illustrating an example of a framework for managing an AI model. In this example, each stage related to an AI model is shown as a block. This example is also referred to as lifecycle management of an AI model.

[0044] The data collection stage corresponds to a stage of collecting data for generating / updating an AI model. The data collection stage may include data organization (e.g., determining which data to transfer for model training / model inference), data transfer (e.g., transferring data to an entity (e.g., UE, gNB) that performs model training / model inference), etc.

[0045] Note that data collection may refer to a process in which data is collected by a network node, a management entity, or a UE for the purpose of AI model training / data analysis / inference. In the present disclosure, the terms "process" and "procedure" may be interpreted interchangeably.

[0046] In the model training stage, model training is performed based on the data (training data) transferred from the collection stage. This stage may include data preparation (e.g., performing data preprocessing, cleaning, formatting, transformation, etc.), model training / validation, model testing (e.g., verifying whether the trained model meets a performance threshold), model exchange (e.g., transferring the model for distributed learning), and model deployment / update (deploying / updating the model to the entity that will perform model inference).

[0047] It should be noted that AI model training may refer to a process for training an AI model in a data-driven manner and obtaining a trained AI model for inference.

[0048] AI model validation may also refer to a sub-process of training that evaluates the quality of an AI model using a dataset different from the dataset used to train the model, which helps select model parameters that generalize beyond the dataset used to train the model.

[0049] AI model testing may also refer to a sub-process of training for evaluating the performance of the final AI model using a dataset different from that used for model training / validation. Note that, unlike validation, testing does not necessarily require subsequent model tuning.

[0050] In the model inference stage, model inference is performed based on the data (inference data) transferred from the collection stage. This stage may include data preparation (e.g., performing data preprocessing, cleaning, formatting, transformation, etc.), model inference, model monitoring (e.g., monitoring the performance of model inference), model performance feedback (feeding back model performance to the entity training the model), and output (providing model output to the actor).

[0051] Additionally, AI model inference may refer to the process of using a trained AI model to produce a set of outputs from a set of inputs.

[0052] Also, a UE side model may refer to an AI model whose inference is performed entirely in the UE, and a network side model may refer to an AI model whose inference is performed entirely in the network (e.g., gNB).

[0053] Also, a one-sided model may refer to a UE-side model or a network-side model. A two-sided model may refer to a pair of AI models in which joint inference is performed. Here, joint inference may include AI inference in which the inference is performed jointly across the UE and the network, e.g., a first part of the inference may be performed first by the UE and the remaining part by the gNB (or vice versa).

[0054] In addition, AI model monitoring may refer to a process for monitoring the inference performance of an AI model, and may be interchangeably read as model performance monitoring, performance monitoring, etc.

[0055] Note that model registration may refer to assigning a version identifier to a model and making the model executable by compiling it into the specific hardware used in the inference stage, and model deployment may refer to distributing (or activating) a fully developed and tested model runtime image (or execution environment image) to (or enabling) a target (e.g., UE / gNB) where inference will be performed.

[0056] An actor stage may include action triggers (e.g., deciding whether to trigger an action on another entity), feedback (e.g., feeding back information needed for training data / inference data / performance feedback), etc.

[0057] For example, training of a model for mobility optimization may be performed in, for example, Operation, Administration and Maintenance (Management) (OAM) / gNodeB (gNB) in a network (NW). In the former case, interoperability, large-capacity storage, operator manageability, and model flexibility (feature engineering, etc.) are advantageous. In the latter case, the latency of model updates and the need for data exchange for model deployment are advantageous. Inference of the above model may be performed in, for example, a gNB.

[0058] The entity that performs training / inference may vary depending on the use case (i.e., the function of the AI ​​model), which may include beam management, beam prediction, autoencoder (or information compression), CSI feedback, positioning, etc.

[0059] For example, for AI-assisted beam management based on measurement reports, the OAM / gNB may perform model training and the gNB may perform model inference.

[0060] For AI-assisted UE-assisted positioning, a Location Management Function (LMF) may perform model training and the LMF may perform model inference.

[0061] For CSI feedback / channel estimation using an autoencoder, the OAM / gNB / UE may perform model training and the gNB / UE may perform model inference (jointly).

[0062] For AI-assisted beam management or AI-assisted UE-based positioning based on beam measurements, the OAM / gNB / UE may perform model training and the UE may perform model inference.

[0063] Note that model activation may mean activating an AI model for a specific function, model deactivation may mean disabling an AI model for a specific function, and model switching may mean deactivating a currently active AI model for a specific function and activating a different AI model.

[0064] Model transfer may also refer to distributing an AI model over the air interface. This distribution may include distributing parameters of a model structure already known at the receiving end, or a new model with parameters, or both. This distribution may include a complete model or a partial model. Model download may refer to transferring a model from the network to the UE. Model upload may refer to transferring a model from the UE to the network.

[0065] (AI-Based CSI Feedback) As a use case of utilizing an AI model, CSI compression using a two-sided AI model is being considered. Such a CSI compression method may be called AI-based CSI feedback and may be realized using, for example, an autoencoder.

[0066] 2 is a diagram illustrating an example of CSI feedback using an encoder / decoder. The UE inputs CSI to an encoder and transmits information (CSI feedback information) including encoded bits output from an antenna. The BS inputs the received CSI feedback information bits to a corresponding decoder to obtain the output CSI.

[0067] The input CSI may include, for example, information on channel coefficients (elements of a channel matrix) or information on precoding coefficients (elements of a precoding matrix). In other words, the CSI may correspond to information on the channel state in the space-frequency domain. Note that the input may include information other than CSI.

[0068] The CSI output from the decoder may be reconstructed CSI corresponding to the input to the encoder, or may be CSI different from the input to the encoder (e.g., information on precoding coefficients if the input information is information on channel coefficients).

[0069] The encoder / decoder may also include pre-processing for the input and post-processing for the output.

[0070] The encoded bits are more compressed than the input information before encoding, and this is expected to reduce the communication overhead required for CSI feedback.

[0071] (Lifecycle Management Framework for Performance Monitoring) In the following, each step in the lifecycle management framework for performance monitoring at the UE / BS will be described for AI-based CSI feedback.

[0072] FIG. 3 illustrates an example lifecycle management framework for performance monitoring in a UE according to an embodiment.

[0073] In the performance monitoring step, the UE monitors the performance of the model and the fallback scheme (non-AI based CSI feedback).

[0074] In the step of model evaluation at the UE, the UE evaluates the performance of the monitored / reported model and fallback scheme (non-AI based CSI feedback).

[0075] In the performance reporting step, the UE reports the monitored performance to the NW.

[0076] In the step of model evaluation in the NW, the NW evaluates the performance of the reported model and fallback scheme.

[0077] In the model request step, the UE sends a request to the NW regarding which model should be applied or whether a fallback scheme should be applied.

[0078] In the model activation / deactivation step, the UE may be instructed which scheme (model) to activate. The UE may activate a model or a fallback scheme.

[0079] Note that some of the steps shown in the figure (for example, steps indicated by dashed lines) may be performed as needed.

[0080] FIG. 4 illustrates an example lifecycle management framework for performance monitoring in a BS according to one embodiment.

[0081] In the step of reporting for performance monitoring, the UE reports information for performance monitoring in the NW (BS).

[0082] In the step of performance monitoring in the NW, the NW monitors the performance of the model and fallback scheme (non-AI based CSI feedback).

[0083] In the step of model evaluation in the NW, the NW evaluates the performance of the model and the fallback scheme.

[0084] In the model activation / deactivation step, the UE may be instructed which scheme (model) to activate. The UE may activate a model or a fallback scheme.

[0085] Note that some of the steps shown in the figure (for example, steps indicated by dashed lines) may be performed as needed.

[0086] In each embodiment described below, the steps shown in FIGS. 3 and 4 will be described in detail.

[0087] (AI-Based Beam Reporting) As a use case of utilizing an AI model, spatial domain downlink (DL) beam prediction or temporal DL beam prediction using a one-sided AI model in a UE or a NW is being considered. Such a beam prediction method may be called AI-based beam prediction (beam reporting), AI-based beam management (BM), etc.

[0088] 5A and 5B are diagrams illustrating an example of AI-based beam reporting. Fig. 5A illustrates spatial domain DL beam prediction. The UE may measure a spatially sparse (or thick) beam, input the measurement results, etc., into an AI model, and output a predicted beam quality result for a spatially dense (or thin) beam.

[0089] 5B shows temporal DL beam prediction. The UE may measure a time series of beams, input the measurement results into an AI model, and output a prediction result of the beam quality of a future beam.

[0090] Note that the spatial domain DL beam prediction may be referred to as BM case 1, and the temporal DL beam prediction may be referred to as BM case 2. Furthermore, the temporal DL beam prediction may be referred to as, for example, time domain CSI prediction.

[0091] Furthermore, the beams / RS associated with the output (prediction result) of the AI ​​model may be referred to as set A. The beams / RS associated with the input of the AI ​​model may be referred to as set B.

[0092] Candidates for input to the AI ​​model for BM Case 1 / 2 include L1-RSRP (Layer 1 Reference Signal Received Power), assistance information (e.g., beam shape information, UE position / direction information, transmit beam usage information), channel impulse response (CIR) information, and corresponding DL transmit / receive beam IDs.

[0093] Possible outputs of the AI ​​model for BM Case 1 include the IDs of the top K (K is an integer) transmit / receive beams, the predicted L1-RSRP of these beams, the probability that each beam will be in the top K, and the angles of these beams.

[0094] In addition to the candidate outputs of the AI ​​model in BM Case 1, the candidate outputs of the AI ​​model in BM Case 2 include predicted beam obstructions.

[0095] (Time Offset of CSI Prediction) It is considered that the UE performs CSI prediction using AI / ML. For time-sequential time beam prediction or time-sequential CSI prediction, predicted values ​​at multiple time instances (prediction time offsets) may be provided.

[0096] The UE may calculate predicted performance of Channel State Information (CSI) corresponding to one or more predicted time offsets and transmit the predicted performance of the CSI to the NW (base station, gNB). The predicted time offset may be, for example, the time difference between the predicted timing of the CSI and the timing of measuring or reporting the CSI.

[0097] The prediction time offset may also be defined as one of the following: Definition 1: The time difference between the time instance associated with the prediction (CSI prediction timing) and the time instance associated with the measurement used for the prediction (CSI measurement timing); Definition 2: The time difference between the time instance associated with the prediction (CSI prediction timing) and the time instance associated with reporting the predicted value (CSI predicted value reporting timing).

[0098] The time instance associated with the prediction (CSI prediction timing) may be, for example, the first / last / middle symbol / slot / subframe of the period, where the predicted value is expressed as a value corresponding to the period.

[0099] The time instance associated with the measurement used for prediction (CSI measurement timing) may be the first / last / middle symbol / slot / subframe of the particular measurement used for prediction. If measurements at multiple time instances are used for prediction, the particular measurement may be the oldest, latest, or middle measurement.

[0100] The time instance associated with the report of the predicted value (CSI predicted value reporting timing) may be the first / last / middle symbol / slot / subframe of the PUSCH / PUCCH resource carrying the report of the predicted value.

[0101] (CSI Calculation Time) An example of the CSI calculation time (processing time for aperiodic CSI reporting) will be described. The UE reports CSI to the base station (gNB) when the following conditions (1) and (2) are met: (1) The time difference #1 between the last symbol of the PDCCH that triggers CSI and the first symbol of the PUSCH is Z symbols or more; (2) When aperiodic CSI-RS is used for reporting, the time difference #2 between the last symbol of the latest aperiodic CSI-RS and the first symbol of the PUSCH is Z' symbols or more.

[0102] 6 is a diagram showing an example of conditions for reporting CSI to a base station. The time gaps (Timi gaps) #1 and #2 in (1) and (2) above are shown in FIG. 6.

[0103] (Z, Z') may depend on the CSI calculation load. In the case of wideband CSI with up to four CSI-RS ports in a single resource without CRI report, and CodebookType is 'typeI-SinglePanel' or reportQuantity is 'cri-RI-CQI' (Condition A), (Z, Z') may be defined as follows. Note that Fig. 7A and Fig. 7B are diagrams showing examples of CSI calculation delay requests. (Z, Z') = (Z 1 , Z 1 ') (see FIG. 7A) (Condition B: single CSI, CSI only / CSI+Transport Block (TB) / CSI+HARQ, occupied CPU=0) (Z, Z')=(Z 1 , Z 1 ') (see Figure 7B) (when condition B is not met)

[0104] If condition A is not satisfied, (Z, Z') may be defined as follows: (Z, Z')=(Z 2 , Z 2 ') (see Figure 7B)

[0105] If the CSI report is an L1-RSRP report, (Z, Z') may be defined as follows: (Z, Z')=(Z 3 , Z 3 ') (see Figure 7B)

[0106] Note that Xμ in FIG. 7B corresponds to the beamReportTiming of the UE capabilities. l corresponds to the UE capability beamSwitchTiming. μ is min(μ PDCCH ,μ CSI-RS ,μ UL )

[0107] The UE may provide a valid CSI report (beam report) and / or update the CSI using the PUSCH if the following conditions are met: The first uplink symbol (Z) after a time gap considering Z has elapsed since the last symbol of the PDCCH that triggers the beam report refThe first uplink symbol (Z') of the CSI report is assigned after the last symbol of the RS (e.g., CSI-RS / SSB) resource of the channel measurement / interference measurement triggered for the CSI report measurement and the first uplink symbol (Z') after a time gap considering Z' has elapsed. ref ) after which the first uplink symbol for CSI reporting is allocated.

[0108] FIG. 8 shows the time gap (Z ref , Z' ref ) is a diagram showing an example of the above Z ref , Z' ref is expressed as shown in FIG.

[0109] The UE may determine at least one of the thresholds Z and Z′ based on values ​​from the CSI calculation delay requirement tables (3GPP TS 38.214 Tables 5.4-1 and 5.4-2) in the existing Rel. 15 / 16 NR.

[0110] Here, Z ref , Z' ref may be determined as follows: Z ref Z may be the next uplink symbol a certain duration after the end of the last symbol of the PDCCH that triggers the CSI report. The certain duration may be determined based on Z. ref may be the next uplink symbol after a predetermined period from the end of the latest non-periodic last symbol of the CSI-RS resource for channel measurement / CSI-IM resource for interference measurement, where the predetermined period may be determined based on Z′.

[0111] (Two-stage (stage / step) beam measurement) In future wireless communication systems (for example, Rel. 18 and later), the introduction of two-stage (stage / step) beam measurement in beam management is being considered.

[0112] In beam measurements using one-stage beam prediction, measurements of beams / RSs in one set (which may be called set B) may be performed, and predictions of beams / RSs in another set (which may be called set A) may be performed.

[0113] The CRI / SSBRI predicted to be of good quality for the top N (N is a specific positive integer) beams among those predicted may be reported, along with the beam quality (e.g., L1-RSRP / L1-SINR) corresponding to the CRI / SSBRI.

[0114] The two-stage beam prediction will be described with reference to FIG.

[0115] In beam measurements using two-stage beam prediction, measurements of beams / RSs in one set (which may be called set B) may be performed first, and then predictions of beams / RSs in another set (which may be called set A) may be performed.

[0116] Next, the top K (K is a specific positive integer) beams / RSs predicted to have good quality among the predicted beams may be measured.

[0117] Furthermore, the CRI / SSBRI of the top K' (K' is a specific positive integer) beams / RSs with the best quality among the K measured beams / RSs may be reported, along with the beam quality (e.g., L1-RSRP / L1-SINR) corresponding to the CRI / SSBRI.

[0118] In this disclosure, the first beam / RS measurement may be referred to as the first measurement or the first stage / step measurement, and in this disclosure, the beam / RS measurement performed after the first measurement may be referred to as the second measurement or the second stage / step measurement.

[0119] A timeline is being considered that takes into account performance monitoring in the two-stage beam measurement described above.

[0120] For example, the performance index calculation may be derived from multiple measurements of the DL-RS.

[0121] Here, the measurements (model inputs) required to execute the model / functionality can be exemplified by the beam measurements in Set B described above.

[0122] Furthermore, the beam measurement of set A described above can be exemplified as a measurement value for performance monitoring (for reference in performance monitoring).

[0123] In this way, the CSI report may be associated with the two types of RS resources mentioned above. Also, it is assumed that the timeline considering the performance monitoring is determined based on the measurement values ​​of the model inputs or the reference measurement values ​​of the performance monitoring.

[0124] CSI Reference Resource The CSI reference resource of the serving cell may be defined as follows: The CSI reference resource is shown in Figure 10: In the frequency domain, the band to which the derived CSI relates; In the time domain, a single DL slot n-n CSI_ref -K offset Assume that the CSI report is transmitted in UL slot n' (the n'th UL slot). The relationship between n and n' is as shown in FIG. 10. That is, n is the DL slot corresponding to the UL slot n' in which the CSI report is transmitted.

[0125] For periodic CSI and semi-persistent CSI reporting, n CSI_ref is the smallest value corresponding to a valid DL slot (4.2 for a single CSI-RS / SSB DL slot). μDL In the case of multiple CSI-RS / SSB DL slots, μDL That's all.

[0126] In the case of aperiodic CSI reporting, n CSI_ref is the minimum value corresponding to a valid DL slot ([Z' / N symb slot ]) Since the UE is instructed by the DCI to report CSI in the same slot as the CSI request, n CSI_ref is in the same slot as the CSI request.

[0127] After (re)configuring CSI reporting, activating a serving cell, changing BWP, or activating semi-persistent CSI, the UE may transmit a CSI report only if a CSI-RS transmission opportunity for channel measurement or a CSI Interference Measurement (CSI-IM) opportunity for interference measurement is received after the CSI reference resource. Otherwise, the UE may drop the CSI report.

[0128] If discontinuous reception (DRX) is configured, the above occasion (transmission opportunity) must be within the DRX active time, otherwise the UE may drop the CSI report.

[0129] For example, if the upper layer parameter ps-TransmitOtherPeriodicCSI is configured, the UE may transmit a CSI report within drx-onDurationTimer even if the CSI is based on an occasion when drx-onDurationTimer does not start.

[0130] If the timeRestrictionForChannelMeasurements in the higher layer parameter CSI-ReportConfig is set to "notConfigured", the UE shall derive the channel measurements for calculating the L1-RSRP reported in UL slot n (nth UL slot) based only on the SS / PBCH or NZP CSI-RS, such that the channel measurements are not later than the CSI reference resource associated with the CSI resource setting.

[0131] That is, the UE must derive the channel measurements (values) for calculating the reported values ​​after the CSI reference resource and based only on the specific RS.

[0132] In this case, it is expected that additional processing time will be required for channel measurement in performance monitoring.

[0133] Furthermore, when the UE derives CSI based on multiple CSI-RS occasions, it is assumed that the latest CSI alone may not be enough to obtain appropriate CSI.

[0134] (CSI Calculation Using AI / ML Inference) The UE may calculate the CSI using AI / ML inference. For example, the UE may apply a predicted RSRP / SINR report and an auto-encoder for CSI feedback. When the UE applies AI / ML inference, the calculation may be performed by the CPU / GPU. When the UE applies AI / ML inference to the CSI calculation, the CSI processing criteria may be extended to take into account the processing capabilities of the AI / ML.

[0135] In the current Rel. 16, the concurrent calculation of CSI is limited by the CPU capacity. If the concurrent CPU processing capacity is greater than the UE's capacity, the UE does not need to prioritize updating some CSI reports.

[0136] Specifically, in the current Rel. 16, the UE supports the number of supported simultaneous CSI calculations, N CPU is denoted by the parameters simultaneousCSI-ReportsPerCC within a component carrier and simultaneousCSI-ReportsAllCC across all component carriers. CPU Supporting simultaneous CSI calculations requires N CPU In a given OFDM symbol, if L CPUs are dedicated to the calculation of CSI reports, the UE can process N CPU -L unoccupied CPUs. CPU In the same OFDM symbol where L CPUs are not occupied, if N CSI reports start occupying their respective CPUs, each CSI report (n=0,...,N-1) CPU (n) , the UE does not need to update the N M requested CSI reports with the lowest priority (Σn=0 M-1 O CPU (n) ≦N CPU Let M be the maximum value for which -L holds (0≦M≦N).

[0137] (CPU Occupancy) CPU Occupancy O CPU The following values ​​can be set for reportQuantity: If reportQuantity is set to none (TRS is applied), O CPU = 0 is set. If reportQuantity is set to 'cri-RSRP', 'ssb-Index-RSRP', 'cri-SINR', 'ssb-Index-SINR' or 'none' (TRS is not applied), O CPU =1 is set.

[0138] In addition, in the following cases (1) to (4), O CPU =N CPU (1) At least one of AP CSI-RS and TB without HARQ-ACK is configured. (2) CPU with L=0 is occupied. (3) CSI is a single CSI in wideband, corresponding to up to four CSI-RS ports without CRI reporting. (4) codebookType is set to typeI-SinglePanel or reportQuantity is set to cri-RI-CQI.

[0139] In all other cases, with certain exceptions, CPU =K S It becomes. K S is the number of CSI-RS resources in the CSI-RS resource set for channel measurement. n=0 M-1 O CPU (n) ≦N CPU -L, CSI report updates may be performed, with a specific exception being group-based beam reporting in Rel. 17.

[0140] Based on the above, CPU usage for reporting monitor results is also being considered. In this case, it is thought that a dedicated definition is required. For example, the following calculations are required to calculate monitor results: - Calculation of inference results - Calculation of performance metrics - If the monitor results are related to the occurrence of an event, confirmation of whether the event occurred based on the performance metrics.

[0141] (Analysis) In the above-mentioned performance monitoring, a method for reporting the monitored results (which may also be called the monitored results) is being considered. Specifically, adoption of a CSI reporting framework for the monitored results reporting is being considered.

[0142] In this case, the specific operations, such as what processes should be performed between measurement (performance evaluation) and reporting, are not clear.Further studies are being conducted on the CSI reporting framework.

[0143] As such, if the various regulations associated with performance monitoring result reports / CSI reports are not clear, it may not be possible to achieve appropriate overhead reduction / high-precision channel estimation / high-efficiency resource utilization, which may hinder improvements in communication throughput / communication quality.

[0144] Therefore, the present inventors have conceived a suitable method for reporting performance monitoring results / CSI.

[0188] (Wireless Communication Method) The embodiments of the present disclosure can be broadly categorized as follows: First embodiment: Periodic / semi-persistent monitoring result reporting. Second embodiment: Aperiodic monitoring result reporting. Third embodiment: CSI calculation delay requirement. Fourth embodiment: Time gap from trigger to report in monitoring result reporting. Fifth embodiment: Dropping of CSI reporting / monitoring result reporting. Sixth embodiment: CSI reference resource for monitoring result reporting. Seventh embodiment: Time limit for CSI reporting / monitoring result reporting. Eighth embodiment: CPU occupancy number in monitoring result reporting.

[0189] Each embodiment will be described below based on these. Each embodiment / option may be applied alone or in combination with other embodiments / options.

[0190] First Embodiment The first embodiment relates to periodic / semi-persistent monitoring result reporting.

[0191] The UE may be configured to report the monitoring results.

[0192] The UE may be configured to report monitoring results specifically as shown in at least one of Alt0 to Alt3 below.

[0193] <Alt0> The UE may be configured with a different reporting configuration for monitoring result reporting than for CSI reporting.

[0194] Furthermore, the CSI report and the monitoring result report may be correlated with each other. In this case, at least one of the following settings Alt1 to Alt3 may be applied to the UE. Alt1 to Alt3 may be applied to, for example, the periodic / semi-persistent reporting case, but are not limited thereto, and may also be applied to other cases.

[0195] <Alt1> Multiple resource settings may be associated with the CSI reporting configuration.

[0196] For example, two or more resource settings for channel measurements may be associated with a CSI reporting setting.

[0197] In this case, one resource setting may correspond to either an RS resource for input (input RS resource) or an RS resource for reference (reference RS resource).

[0198] <Alt2> Multiple CSI-RS resource sets (selected from one resource setting) may be associated with a CSI reporting setting.

[0199] In this case, one CSI-RS resource set may correspond to either RS ​​resources for input (input RS resources) or RS resources for reference (reference RS resources).

[0200] <Alt3> Multiple CSI-RS resources (selected) from one CSI-RS resource set may be associated with a CSI reporting setting.

[0201] In this case, one CSI-RS resource set may include RS resources for input (input RS resources) and RS resources for reference (reference RS resources).

[0202] Also, in Alt3, the slot offset between the input RS resource and the reference RS resource may be set / indicated or may be determined based on UE capabilities / predefined rules.

[0203] According to the first embodiment described above, periodic / semi-persistent monitoring result reporting can be appropriately controlled.

[0204] Second Embodiment The second embodiment relates to aperiodic monitoring result reporting.

[0205] The UE may trigger a monitoring result report.

[0206] If the CSI report is associated with a monitoring result report, the UE may be configured with at least one of the following Alt1 to Alt4.

[0207] <Alt1> One CSI-RS resource set (selected) from one resource setting may be associated with each trigger state.

[0208] In this case, one CSI-RS resource set may include RS resources for input (input RS resources) and RS resources for reference (reference RS resources).

[0209] The input RS resource and the reference RS resource may be scheduled in different slots, so that the input RS resource and the reference RS resource can have different timing offsets (slot offsets).

[0210] In Alt1, at least one of the following options 1-2 may also be applied:

[0211] (Option 1) When one aperiodic RS resource set has multiple RS resources, the RS triggering offset may be configured for each RS resource or for each RS resource set (e.g., including multiple RS resources).

[0212] (Option 2) The slot offset between the input RS resource and the reference RS resource may be configured / indicated or may be determined based on UE capability / predefined rules.

[0213] <Alt2> Multiple CSI-RS resource sets (selected from one resource setting) may be associated with each trigger state.

[0214] In this case, one CSI-RS resource set may correspond to either the input RS resource or the reference RS resource, so that the input RS resource and the reference RS resource can have different timing offsets (slot offsets).

[0215] <Alt3> One or more CSI-RS resource sets (selected from multiple resource settings) may be associated with each trigger state.

[0216] In this case, one resource setting may correspond to either the input RS resource or the reference RS resource, so that the input RS resource and the reference RS resource can have different timing offsets (slot offsets).

[0217] <Alt4> Different trigger conditions may be set to trigger RS ​​resources for aperiodic model input (model input RS resources) and reference RS resources.

[0218] In this case, the trigger for the monitoring result report can be associated with any trigger condition.

[0219] According to the second embodiment described above, it is possible to appropriately control non-periodic monitoring result reports.

[0220] <Variations of the First / Second Embodiments> In the first / second embodiments, the UE may expect at least one of the following restrictions for input RS resources / reference RS resources associated with one CSI reporting setting / one trigger state:

[0221] - Same time domain behavior (e.g. periodic / semi-persistent / aperiodic). - Same frequency (e.g. PRB / band / frequency domain resource allocation). - Same periodicity (periodic / semi-persistent). - The RS occasion time gap between the input RS resource and the reference RS resource is the same as the predicted time offset of the associated model / functionality. - The "time gap between the input RS resource and the reference RS resource" - "the predicted time offset of the associated model / functionality" is smaller than a certain threshold, which may be determined based on UE capabilities / predefined rules. - The same number of CSI-RS resources are included for each resource set. The resource set may be prepared for the input RS resource / reference RS resource. - Same frequency density.

[0222] If the UE is configured to report the monitoring result, a specific parameter may be set to associate the monitoring result report with the CSI reporting setting, for example, the specific parameter may be information about the reporting quantity.

[0223] The set (configurable) value may be a model ID / functionality ID or a value specific to the content of the monitoring result, such as a value related to an event occurrence / performance index or a value according to a calculated performance index.

[0224] Third Embodiment The third embodiment relates to a CSI computation delay requirement.

[0225] The CSI request field of the DCI may trigger a CSI report on the PUSCH. For example, when the CSI request field of the DCI triggers a CSI report for a monitoring result on the PUSCH, the UE may determine one of the following values ​​from Options 1 to 5 as the time gap (Z, Z') until the transmission of the CSI report. That is, the UE may control the timing of the CSI report (monitoring result report) based on the following options. Note that this time gap may also be referred to as a CSI calculation delay requirement.

[0226] <Option 1> Values ​​from an existing CSI calculation delay requirement table (e.g., table 5.4.-1 in 3GPP Rel. 17 38.214).

[0227] <Option 2> A value obtained by adding an additional value to an existing value in an existing CSI calculation delay requirement table. In this case, the UE may request additional calculation time (additional value) for a monitoring report (monitoring result report) in addition to the existing CSI calculation time (existing value). The existing value and the existing CSI calculation time may be interchangeable. The additional value and the additional calculation time may be interchangeable.

[0228] The additional value of option 2 may be at least one of the following: A unique value per model / functionality or the same value across multiple models / functionalities, A value dependent on the content of the reported monitoring result (e.g. a value related to an event occurrence / performance index or a value according to a calculated performance index).

[0229] These additional values ​​may be determined based on UE capabilities / predefined rules, or as a variation, it may be assumed that if the corresponding UE capabilities are not reported, a default additional value specified in the specification will be applied, i.e. the UE may assume the default additional value specified in the specification if it does not report the UE capabilities.

[0230] The additional value may be determined based on at least one of the following: - configured / indicated parameters; - CSI-RS resource of the associated channel / interference measurement, time difference between RS occasions (e.g. offset between slots); - time domain behavior of the CSI-RS resource of the associated channel measurement (e.g. periodic / semi-persistent / aperiodic); - predicted time offset of the associated model / functionality; - number of time instances associated with the value (result) to be reported (e.g. number of slots associated with the predicted value to be reported).

[0231] <Option 3> A value obtained by adding an additional value to the value in the CSI calculation delay requirement table for the model inference report of the monitored model / functionality. In this case, the UE may request additional calculation time (additional value) for the monitoring report (monitoring result report) in addition to the CSI calculation time for the model inference report. Note that the additional value may be determined in the same way as in Option 2 above.

[0232] <Option 4> The same value as the value in the CSI calculation delay requirement table for model inference reporting of the monitored model / functionality (same CSI calculation delay requirement), or the same value as the additional calculation time (additional value) for monitoring reporting (monitoring result reporting).

[0233] <Option 5> New value for CSI calculation delay requirement for monitoring result reporting.

[0234] The new value in option 5 may be at least one of the following: A unique value per model / functionality or the same value across multiple models / functionalities, A value dependent on the content of the reported monitoring result (e.g. a value related to an event occurrence / performance index or a value according to a calculated performance index).

[0235] The new value may be determined based on at least one of the following: - configured / indicated parameters; - CSI-RS resource of the associated channel / interference measurement, time difference between RS occasions (e.g. offset between slots); - time domain behavior of the CSI-RS resource of the associated channel measurement (e.g. periodic / semi-persistent / aperiodic); - predicted time offset of the associated model / functionality; - number of time instances associated with the value (result) to be reported (e.g. number of slots associated with the predicted value to be reported).

[0236] These new values ​​may be determined based on UE capabilities / predefined rules, or as a variation, it may be assumed that if no corresponding UE capabilities are reported, a default additional value specified in the specification applies, i.e. the UE may assume the default additional value specified in the specification if it does not report that UE capability.

[0237] According to the third embodiment described above, the UE can appropriately determine / judge the CSI calculation delay requirement (time gap) for CSI reporting / monitoring result reporting.

[0238] <Fourth Embodiment> The fourth embodiment relates to the time gap between the trigger and the report in the monitoring result report.

[0239] For monitoring result reports, if the first UL symbol for transmitting the nth CSI report including the effect of timing advance starts earlier than at least one of options 1 to 3 below, the UE may ignore the scheduling CSI or may not be required to update the CSI for the triggered CSI report.

[0240] <Option 1> Among the latest symbols of the aperiodic CSI resource for model input, a symbol of a certain period after the last symbol in time. <Option 2> Among the latest symbols of the aperiodic CSI resource for performance monitoring reference, a symbol of a certain period after the last symbol in time.

[0241] <Option 3> Symbols in a certain period from (after) the last symbol in time of the latest symbol among the CSI resources for model input / performance monitoring reference. That is, symbols calculated from the latest symbol among Option 1 and Option 2.

[0242] The certain duration may vary for each option and may be derived from the CSI calculation delay requirement in the third embodiment.

[0243] According to the fourth embodiment described above, it is possible to appropriately control the time gap between the trigger and the report in the monitoring result report.

[0244] Fifth Embodiment The fifth embodiment relates to dropping of CSI reports / monitoring result reports.

[0245] The fifth embodiment can be further classified into aspects 5-1 to 5-3 depending on the conditions for dropping CSI reports.

[0246] [Aspect 5-1] After configuring / reconfiguring CSI reporting, if at least one of the conditions of the following options 1 to 3 is met, the UE may drop the monitoring result report.

[0247] <Option 1> When there is no CSI-RS transmission opportunity for channel measurement or no CSI Interference Measurement (CSI-IM) opportunity for model input after the CSI reference resource.

[0248] <Option 2> When there is no CSI-RS transmission opportunity for channel measurement or no CSI-IM opportunity for performance monitoring reference after the CSI reference resource.

[0249] <Option 3> When the CSI-RS transmission opportunity for channel measurement or the CSI-IM opportunity for model input and performance monitoring reference does not exist after the CSI reference resource, that is, when the conditions of both Option 1 and Option 2 are satisfied.

[0250] <Variations> If the monitoring results are associated with the performance of a model / functionality that requests (requires) multiple CSI-RS transmission opportunities / CSI-IM opportunities to derive an output (e.g., temporal CSI prediction, temporal beam prediction), the UE may apply the above options 1 to 3 with the following modifications:

[0251] "There are no CSI-RS transmission opportunities for channel measurement" should be read as "There are not more than X CSI-RS transmission opportunities for channel measurement." "There are no CSI-IM opportunities" should be read as "There are not more than Y CSI-IM opportunities."

[0252] The above X and Y may be configured / instructed parameters, parameters reported in UE capabilities, predefined parameters, or parameters associated with a model / functionality. Furthermore, X and Y may be common parameters or different parameters. Defining X and Y is effective when multiple opportunities for time prediction are assumed.

[0253] [Aspect 5-2] After configuring / reconfiguring CSI reporting, if the UE requests (requires) multiple CSI-RS transmission opportunities / CSI-IM opportunities for deriving an output (e.g., temporal CSI prediction, temporal beam prediction), the UE may drop the report of the results calculated by the model / functionality.

[0254] Furthermore, the following conditions may be applied (additionally): If there are X or more CSI-RS transmission opportunities for channel measurements after the CSI reference resource, If there are Y or more CSI-IM opportunities for model inference measurements after the CSI reference resource.

[0255] The above-mentioned X and Y may be determined in the same manner as in aspect 5-1.

[0256] [Aspect 5-3] After configuring / reconfiguring CSI reporting, if multiple CSI-RS / CSI-IM opportunities are required for calculating (deriving) a precoding matrix indicator (PMI), the UE may drop the report of the predicted PMI.

[0257] The predicted PMI may be, for example, an extended type 2 predicted PMI or a predicted PMI for extended type 2 port selection.

[0258] Furthermore, the following conditions may be applied (additionally): If there are X or more CSI-RS transmission opportunities for channel measurements after the CSI reference resource, If there are Y or more CSI-IM opportunities for model inference measurements after the CSI reference resource.

[0259] The above X and Y may be determined in the same manner as in aspects 5-1 and 5-2.

[0260] [Variation] For example, when discontinuous reception (DRX) is configured, the conditions of the above-described aspects 5-1 to 5-3 need to be satisfied within the active time of DRX. That is, when DRX is configured and the conditions of aspects 5-1 to 5-3 are satisfied within the active time of DRX, the UE may drop the corresponding CSI report / monitoring result report.

[0261] Furthermore, if the drx-onDurationTimer is not started and the UE is configured not to transmit CSI reports (for example, if the upper layer parameters ps-TransmitOtherPeriodicCSI and TransmitPeriodicL1-RSRP are set), if there is a CSI report when the drx-onDurationTimer is started, it may be assumed that the UE satisfies at least one of the conditions of aspects 5-1 to 5-3 described above, even if the drx-onDurationTimer is not started.

[0262] Furthermore, if the UE is not configured not to transmit CSI reports (for example, if the upper layer parameters ps-TransmitOtherPeriodicCSI and TransmitPeriodicL1-RSRP are not configured), at least one of the conditions of the above-mentioned aspects 5-1 to 5-3 must be met when the drx-onDurationTimer is started.

[0263] According to the fifth embodiment described above, dropping of CSI reports / monitoring result reports can be appropriately controlled.

[0264] Sixth Embodiment The sixth embodiment relates to a CSI reference resource for reporting monitoring results.

[0265] The UE may determine the time domain of the CSI reference resource for reporting the monitoring result using at least one of the following options 1 to 3. Note that in the current specification, a valid DL slot consists of at least one DL or flexible symbol configured by a higher layer and is not within the measurement gap configured for the UE.

[0266] For example, the UE may determine the time domain of the CSI reference resource based on at least one of related information of the AI / ML model / functionality, parameters of the UE capabilities (terminal capabilities), parameters set / indicated by physical layer signaling / higher layer signaling, and calculated indicators (performance indicators) associated with the monitoring result report.

[0267] [Option 1] As in Rel. 17 above, the time domain of the CSI reference resource is n-n CSI_ref It may be a single DL slot in

[0268] <<Options 1-1 and 1-2>> CSI_ref may be the smallest value greater than X that corresponds to a valid DL slot.

[0269] X is 4.2 μDL or 5.2 μDL or may be a different value. X may depend on the DL numerology (subcarrier spacing).

[0270] The value of X may be determined based on at least one of the following: - configured / indicated parameters; - CSI-RS resource of the associated channel / interference measurement, time difference between RS occasions (e.g. offset between slots); - time domain behavior of the CSI-RS resource of the associated channel measurement (e.g. periodic / semi-persistent / aperiodic); - predicted time offset of the associated model / functionality; - number of time instances associated with the value (result) to be reported (e.g. number of slots associated with the predicted value to be reported).

[0271] <<Option 1-1>> X may be determined based on at least one of the following: relevant information of the AI / ML model / functionality (such as the function / FLOP / total parameters of the applied AI / ML model), parameters of the UE capabilities, parameters set / instructed by physical layer signaling / higher layer signaling, and calculated indicators (performance indicators) associated with the monitoring result report.

[0272] <<Option 1-2>> X may be specified in the specification independently of the AI / ML model / functionality and the calculated indicators (performance indicators) associated with the monitor result reports.

[0273] Options 1-1 and 1-2 may be applied to periodic / semi-persistent CSI reporting derived from the model / functionality.

[0274] Options 1-3 and 1-4 CSI_ref corresponds to a valid DL slot, [Z'+Y / N symb slot ] may be a minimum value greater than

[0275] <<Options 1-3>> The above Y may be determined based on at least one of the following: relevant information of the AI / ML model / functionality (such as functions / FLOPs / total parameters of the applied AI / ML model), parameters of the UE capabilities, parameters set / instructed by physical layer signaling / higher layer signaling, and calculated indicators (performance indicators) associated with the monitoring result report.

[0276] The value of Y may be determined based on at least one of the following: - configured / indicated parameters; - CSI-RS resource of the associated channel / interference measurement, time difference between RS occasions (e.g. offset between slots); - time domain behavior of the CSI-RS resource of the associated channel measurement (e.g. periodic / semi-persistent / aperiodic); - predicted time offset of the associated model / functionality; - number of time instances associated with the value (result) to be reported (e.g. number of slots associated with the predicted value to be reported).

[0277] <<Options 1-4>> Y may be specified in the specification independently of the AI / ML model / functionality and the calculated indicators (performance indicators) associated with the monitor result reports.

[0278] Z' may be determined in the same manner as in the third embodiment. Options 1-3 and 1-4 may be applied to aperiodic CSI reporting derived from the model / functionality.

[0279] [Option 2] In the time domain of the CSI reference resource, n CSI_ref / nCSI_ref_AI may be the same as the reported result derived from the model / functionality associated with the monitor result report. CSI_ref may be determined similarly.

[0280] [Option 3] The time domain of the CSI reference resource is n-n CSI_ref - nCSI_ref_AI - may be a single DL slot in nCSI_ref_monitoring. nCSI_ref_monitoring is n in Option 1 CSI_ref may be determined similarly.

[0281] The processing time of the monitoring result is larger than the processing time of the inference result, so by considering an additional offset from the CSI reference resource for the inference result, the timing of the CSI report can be controlled more appropriately.

[0282] According to the sixth embodiment described above, it is possible to appropriately control the time domain of the CSI reference resource for reporting the monitoring result.

[0283] Seventh Embodiment The seventh embodiment relates to a time limit for reporting CSI / monitoring results based on multiple occasions.

[0284] When the UE derives CSI based on multiple CSI-RS occasions, it is assumed that the latest CSI alone may not be enough to obtain adequate CSI.

[0285] Therefore, in this embodiment, a time limit for CSI reporting based on multiple occasions will be described.

[0286] The seventh embodiment can be further classified into aspects 7-1 to 7-3 depending on specific conditions.

[0287] [Aspect 7-1] When certain higher layer parameters are configured, the UE must derive channel measurements for calculating a monitored result value to be reported in the n-th UL slot.

[0288] In this case, the UE may derive the channel measurement based on (only) the most recent X occasions that are not later than (not later than) the CSI reference resource for the SS / PBCH or NZP CSI-RS associated with the CSI resource setting.

[0289] The above X may be a configured / indicated parameter, a parameter reported in the UE capabilities, a predefined parameter, or a parameter associated with a model / functionality.

[0290] Furthermore, the above-mentioned specific upper layer parameter may be a parameter relating to a time restriction for channel measurements (eg, timeRestrictionForChannelMeasurements).

[0291] [Aspect 7-2] When certain higher layer parameters are configured, the UE must derive channel measurements to calculate a result value to be reported in the nth UL slot. The result value may be an output derived from a model / functionality that requires multiple RS occasions (e.g., temporal CSI prediction, temporal beam prediction).

[0292] In this case, the UE may derive the channel measurement based on (only) the most recent X occasions that are not later than (not later than) the CSI reference resource for the SS / PBCH or NZP CSI-RS associated with the CSI resource setting.

[0293] The above X may be a configured / indicated parameter, a parameter reported in the UE capabilities, a predefined parameter, or a parameter associated with a model / functionality.

[0294] Furthermore, the above-mentioned specific upper layer parameter may be a parameter relating to a time restriction for channel measurements (eg, timeRestrictionForChannelMeasurements).

[0295] [Aspect 7-3] When certain higher layer parameters are configured, the UE must derive channel measurements to calculate a predicted PMI to be reported in the nth UL slot. The predicted PMI may be, for example, a predicted PMI for Extended Type 2 or a predicted PMI for Extended Type 2 port selection.

[0296] In this case, the UE may derive the channel measurement based on (only) the most recent X occasions that are not later than (not later than) the CSI reference resource for the SS / PBCH or NZP CSI-RS associated with the CSI resource setting.

[0297] The above X may be a configured / indicated parameter, a parameter reported in the UE capability, or a predefined parameter (e.g., N 4 where N 4 may represent the length of the basis vectors (DFT basis vectors) in the Doppler domain (DD) / time domain (TD) (number of DD / TD bases). 4 may be set by higher layer signaling.

[0298] Furthermore, the above-mentioned specific upper layer parameter may be a parameter relating to a time restriction for channel measurements (eg, timeRestrictionForChannelMeasurements).

[0299] [Variations] The UE may not expect certain higher layer parameters (eg, timeRestrictionForChannelMeasurements) mentioned above to be set for reporting predicted PMI.

[0300] According to the seventh embodiment described above, it is possible to appropriately control channel measurement based on multiple CSI-RS occasions.

[0301] Eighth Embodiment The eighth embodiment relates to the CPU occupation number in the monitoring result report.

[0302] As mentioned above, CPU occupancy for reporting monitor results is also being considered. In this case, a dedicated definition is considered necessary. For example, the calculation of monitor results requires the following calculations: Calculation of inference results Calculation of performance metrics If the monitor results are related to the occurrence of an event, confirmation of whether the event has occurred based on the performance metrics.

[0303] The definition of the CPU occupation number taking these monitoring results into consideration will be explained below.

[0304] The CPU occupancy number for the monitor result report may be defined based on any of Alt1 to Alt3 below.

[0305] <Alt1> A new value / expression may be defined as the CPU occupancy for monitor results reporting.

[0306] <Alt2> Sum of CPU occupancy and additional values ​​for reporting information derived from the model / functionality.

[0307] <Alt3> Same value as CPU occupancy for reporting information derived from model / functionality.

[0308] The new value / formula in Alt1 and the additional value in Alt2 may be determined based on at least one of the following: - A unique value per model / functionality or the same value across multiple models / functionalities - A value dependent on the content of the reported monitoring result (e.g. a value related to an event occurrence / performance index or a value according to a calculated performance index).

[0309] These values ​​(new values / formulas or additional values) may be determined based on UE capabilities / predefined rules, or as a variation, it may be assumed that if the corresponding UE capability is not reported, a default value specified in the specification will be applied, i.e. the UE may assume the default value specified in the specification if it does not report the UE capability.

[0310] According to the eighth embodiment described above, the number of CPUs occupied can be clarified in the monitoring result report.

[0357] (Wireless Communication System) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0358] 11 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may be simply referred to as system 1) may be a system that realizes communication using Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) specified by the Third Generation Partnership Project (3GPP).

[0359] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0360] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (Master Node (MN)), and the NR base station (gNB) is the secondary node (Secondary Node (SN)). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0361] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0362] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The locations and numbers of the cells and user terminals 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0363] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CCs) and dual connectivity (DC).

[0364] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a higher frequency band than FR2.

[0365] Furthermore, the user terminal 20 may perform communication using at least one of time division duplex (TDD) and frequency division duplex (FDD) in each CC.

[0366] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

A single network node may provide multiple functions. Communication with an external network (e.g., the Internet) may also be performed via the DN.

[0369] The user terminal 20 may be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0370] An Orthogonal Frequency Division Multiplexing (OFDM)-based radio access scheme may be used in the wireless communication system 1. For example, Cyclic Prefix OFDM (CP-OFDM), Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), or the like may be used in at least one of the downlink (DL) and uplink (UL).

[0374] The PDSCH transmits user data, higher layer control information, a System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit a Master Information Block (MIB).

[0375] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information for at least one of the PDSCH and the PUSCH.

[0376] Note that the DCI for scheduling the PDSCH may be referred to as a DL assignment, a DL DCI, etc., and the DCI for scheduling the PUSCH may be referred to as a UL grant, a UL DCI, etc. Note that the PDSCH may be replaced with DL data, and the PUSCH may be replaced with UL data.

[0377] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources for searching for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or more search spaces. The UE may monitor the CORESET associated with a certain search space based on the search space configuration.

[0378] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be referred to as a search space set. Note that the terms "search space," "search space set," "search space configuration," "search space set configuration," "CORESET," "CORESET configuration," and the like in the present disclosure may be read interchangeably.

[0379] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), delivery confirmation information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0380] In the present disclosure, downlink, uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning.

[0381] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, as the DL-RS, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted.

[0382] The synchronization signal may be, for example, at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). A signal block including an SS (PSS, SSS) and a PBCH (and a DMRS for the PBCH) may be referred to as an SS / PBCH block, an SS Block (SSB), or the like. Note that the SS, SSB, and the like may also be referred to as a reference signal.

[0383] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), or the like may be transmitted as an uplink reference signal (UL-RS).

[0439] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0440] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by a transceiver in the frequency domain, and specific windowing performed by a transceiver in the time domain.

[0441] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may also be a time unit based on numerology.

[0442] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0443] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0444] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0445] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0446] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0447] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0448] A TTI having a time length of 1 ms may be called a regular TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0449] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and greater than or equal to 1 ms.

[0450] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0451] In addition, an RB may include one or more symbols in the time domain and may have a length of one slot, one minislot, one subframe, or one TTI, each of which may be composed of one or more resource blocks.

[0452] In addition, one or more RBs may be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0453] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0454] A Bandwidth Part (BWP), which may also be referred to as a partial bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0455] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0456] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0457] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0458] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

Furthermore, the mathematical expressions and the like using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

[0461] Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via multiple network nodes.

[0462] Input and output information, signals, etc. may be stored in a specific location (for example, memory) or may be managed using a management table. Input and output information, signals, etc. may be overwritten, updated, or added. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

[0463] The notification of information is not limited to the aspects / embodiments described in the present disclosure, and may be performed using other methods. For example, the notification of information in the present disclosure may be performed by physical layer signaling (e.g., Downlink Control Information (DCI) and Uplink Control Information (UCI)), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB) and System Information Block (SIB)), Medium Access Control (MAC) signaling), other signals, or a combination thereof.

[0464] Note that the physical layer signaling may be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. Furthermore, the RRC signaling may be referred to as an RRC message, such as an RRC Connection Setup message or an RRC Connection Reconfiguration message. Furthermore, the MAC signaling may be notified using, for example, a MAC Control Element (CE).

[0465] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0466] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value represented by true or false, or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).

For example, if software is transmitted from a website, server, or other remote source using wired technologies (such as coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL)), and / or wireless technologies (such as infrared, microwave), these wired and / or wireless technologies are included within the definition of transmission media.

[0469] As used in this disclosure, the terms "system" and "network" may be used interchangeably. A "network" may refer to devices included in the network (e.g., base stations).
