[0029] (Application of Artificial Intelligence (AI) Technology to Wireless Communications)

[0030] Regarding future wireless communication technologies, research is underway into utilizing AI technologies such as machine learning (ML) for network and device control and management.

[0031] For example, research is underway into the use of AI in terminals (user terminals, user equipment (UE)) and base stations (BS) to improve channel state information (CSI) feedback (e.g., reduced overhead, improved accuracy, prediction), beam management (e.g., improved accuracy, prediction in the time and spatial domains), and position measurement (e.g., improved position estimation and prediction).

[0032] The AI model can also output at least one of an estimated value, a predicted value, a selected operation, a classification, etc. based on the input information. The UE / BS can also input channel state information, reference signal measurement values, etc. into the AI model, and output high-precision channel state information / measurement values / beam selection / position, future channel state information / radio link quality, etc.

[0033] In addition, in the present disclosure, AI can also be rewritten as an object (also referred to as object, object, data, function, program, etc.) having (implementing) at least one of the following characteristics:

[0034] Estimates based on observed or collected information;

[0035] Selection based on observed or collected information;

[0036] Predictions based on observed or collected information.

[0037] In this disclosure, the terms “estimate,” “predict,” and “infer” can be replaced with each other. Furthermore, in this disclosure, the terms “estimate,” “predict,” and “infer” can be replaced with each other.

[0038] In the present disclosure, an object may also be, for example, a device or apparatus such as a UE or a BS. In addition, in the present disclosure, an object may also correspond to a program / model / entity operating in the apparatus.

[0039] In addition, in the present disclosure, the AI model can also be rewritten as an object having (implementing) at least one of the following features:

[0040] Generating estimates by feeding information;

[0041] By providing information, forecasting estimated values;

[0042] Discover features by providing information;

[0043] · Select an action by providing information.

[0044] Furthermore, in the present disclosure, an AI model may also refer to a data-driven algorithm that applies AI technology to generate a set of outputs based on a set of inputs.

[0045] Furthermore, in the present disclosure, AI models, models, ML models, predictive analytics, predictive analytics models, tools, autoencoders, encoders, decoders, neural network models, AI algorithms, schemes, and the like may be interchangeable. Furthermore, AI models may be derived using at least one of regression analysis (e.g., linear regression analysis, multiple regression analysis, logistic regression analysis), support vector machines, random forests, neural networks, deep learning, and the like.

[0046] In this disclosure, autoencoders can be interchanged with any other autoencoders, such as stacked autoencoders and convolutional autoencoders. The encoder / decoder of this disclosure can also use models such as Residual Network (ResNet), DenseNet, and RefineNet.

[0047] In addition, in the present disclosure, encoder, encoding, encoding / encoded, correction / change / control based on the encoder, compression, compressing / compressed, generating, generating / generated, etc. can also be rewritten.

[0048] In addition, in the present disclosure, decoder, decoding, decoding / decoding, correction / change / control based on the decoder, decompression, decompression / decompressed, reconstruction, reconstruction / reconstruction, etc. can also be rewritten.

[0049] In the present disclosure, layers (related to AI models) may also be mutually rewritten with layers (input layers, intermediate layers, etc.) used in the AI model. Layers in the present disclosure may also correspond to at least one of input layers, intermediate layers, output layers, batch normalization layers, convolutional layers, activation layers, dense layers, normalization layers, pooling layers, attention layers, dropout layers, fully connected layers, etc.

[0050] In the present disclosure, AI model training methods may also include supervised learning, unsupervised learning, reinforcement learning, federated learning, etc. Supervised learning may also refer to the process of training a model based on input and corresponding labels. Unsupervised learning may also refer to the process of training a model without labeled data. Reinforcement learning may also refer to the process of training a model based on input (in other words, state) and feedback signals (in other words, rewards) generated from the model's output (in other words, action) in an environment where the model interacts.

[0051] In this disclosure, the terms "generate," "calculate," and "derive" can be used interchangeably. In this disclosure, the terms "implement," "run," "operate," and "execute" can be used interchangeably. In this disclosure, the terms "train," "learn," "update," and "retrain" can be used interchangeably. In this disclosure, the terms "infer," "post-training," "formal utilization," and "actual utilization" can be used interchangeably. In this disclosure, the terms "signal" and "signal / channel" can be used interchangeably.

[0052] Figure 1 This diagram shows an example of a framework for managing AI models. In this example, each stage associated with an AI model is represented by a block. This example also represents the AI model lifecycle management (LCM).

[0053] The data collection phase involves gathering data for generating and updating AI models. This phase may also include data organization (e.g., determining which data to migrate for model training and inference) and data migration (e.g., migrating data to entities performing model training and inference (e.g., UEs and gNBs)).

[0054] Additionally, data collection can also refer to the process of collecting data by a network node, management entity, or UE for the purpose of AI model training, data analysis, or inference. In this disclosure, the terms "process" and "procedure" can be interchangeable. Furthermore, in this disclosure, "collection" can also refer to the acquisition of a dataset for AI model training / inference (e.g., usable as input / output) based on measurements (e.g., channel measurements, beam measurements, radio link quality measurements, position estimation, etc.).

[0055] In this disclosure, offline field data can also be data collected from the field (real world) and used for offline training of AI models. In addition, online field data can also be data collected from the field (real world) and used for online training of AI models.

[0056] During the model training phase, model training is performed based on the data (training data) migrated from the collection phase. This phase may also include data preparation (e.g., data preprocessing, cleaning, formatting, and transformation), model training / validation (e.g., confirming that the trained model meets performance thresholds), model exchange (e.g., migrating models for distributed learning), and model deployment / updates (deploying / updating the model to the entities performing model inference).

[0057] In addition, AI model training can also refer to the process of training an AI model through a data-driven approach to obtain a trained AI model for inference.

[0058] AI model validation can also refer to a sub-process of training that uses a dataset different from the one used in model training to evaluate the quality of an AI model. This sub-process helps select model parameters that generalize beyond the dataset used in model training.

[0059] Furthermore, AI model testing can also refer to a sub-process of training that uses a different dataset from the one used in model training / validation to evaluate the performance of the final AI model. Furthermore, testing, unlike validation, does not necessarily require subsequent model tuning.

[0060] In the model inference phase, model inference is performed based on the data (inference data) transferred from the collection phase. This phase may also include data preparation (e.g., data preprocessing, cleaning, formatting, and transformation), model inference, model monitoring (e.g., monitoring model inference performance), model performance feedback (feedback on model performance to the entity performing model training), and output (providing model output to actors).

[0061] In addition, AI model inference can also refer to the process of using a trained AI model to generate a set of outputs based on a set of inputs.

[0062] Furthermore, a UE-side model may also refer to an AI model whose reasoning is fully implemented in the UE. A network-side model may also refer to an AI model whose reasoning is fully implemented in the network (e.g., gNB).

[0063] Furthermore, a one-sided model can also refer to a UE-side model or a network-side model. A two-sided model can also refer to a paired AI model that performs joint inference. Joint inference can also include AI inference performed jointly across the UE and the network. For example, the first part of the inference can be performed by the UE, and the remaining part by the gNB (or vice versa).

[0064] In addition, AI model monitoring can also refer to the processing used to monitor the inference performance of AI models, and can also be interchanged with model performance monitoring, performance monitoring, etc.

[0065] Model registration also refers to assigning a version identifier to a model and enabling its execution by compiling it for specific hardware used during inference. Furthermore, model deployment also refers to distributing (or activating in) the runtime image (or execution environment image) of a fully developed and tested model to the target (e.g., UE / gNB) where inference is performed.

[0066] The actor phase may also include action triggers (e.g., deciding whether to trigger an action on other entities), feedback (e.g., providing training data / inference data / information required for performance feedback), etc.

[0067] Furthermore, training models for mobility optimization, for example, can also be performed in the Operation, Administration, and Maintenance (OAM) / gNodeB (gNB) within the network (NW). The former benefits from interoperability, large storage capacity, operator manageability, and model flexibility (e.g., feature engineering). The latter is advantageous because it eliminates the need for latency in model updates and data exchange for model decompression. Inference of these models can also be performed in the gNB, for example.

[0068] The entity performing training / inference can also vary depending on the use case (in other words, the function of the AI model). The functions of the AI model can also include beam management, beam prediction, autoencoder (or information compression), CSI feedback, position positioning, etc.

[0069] For example, for AI-assisted beam management based on measurement reports, OAM / gNB can also perform model training and gNB can perform model inference.

[0070] For AI-assisted UE assisted positioning, the Location Management Function (LMF) can also be used for model training, and the LMF performs model inference.

[0071] For CSI feedback / channel estimation using autoencoders, OAM / gNB / UE can also perform model training, and gNB / UE can perform model inference (jointly).

[0072] For AI-assisted beam management based on beam measurement or AI-assisted UE-based positioning, OAM / gNB / UE can also perform model training and UE can perform model inference.

[0073] In addition, model activation can also mean activating an AI model for a specific function. Model deactivation can also mean deactivating an AI model for a specific function. Model switching can also mean deactivating the currently activated AI model for a specific function and activating a different AI model.

[0074] Furthermore, model transfer can also refer to the distribution of an AI model over the air interface. This distribution can also include distributing one or both of the following to the receiving side: parameters of a known model structure, or a new model with parameters. Furthermore, this distribution can include a complete model or a partial model. Model download can also refer to the transfer of a model from the network to the UE. Model upload can also refer to the transfer of a model from the UE to the network.

[0075] (AI-based beam prediction)

[0076] As a use case for leveraging AI models, research is underway into spatial downlink (DL) beam prediction and temporal DL beam prediction using a single-sided AI model in the UE or NW. This beam prediction method is also known as AI-based beam prediction (beam reporting) or AI-based beam management (BM).

[0077] Figure 2A as well as Figure 2B This is a diagram showing an example of AI-based beam prediction. Figure 2A Indicates spatial domain DL beam prediction. The UE can also measure spatially sparse (or coarse) beams, input the measurement results and other information into the AI model, and output the prediction result of the beam quality of spatially dense (or thin) beams.

[0078] Figure 2B Indicates DL beam prediction over time. The UE can also measure the beam in time sequence, input the measurement results into the AI model, and output the prediction result of the beam quality of the future beam.

[0079] In addition, spatial domain DL beam prediction may also be referred to as BM case 1, and temporal DL beam prediction may also be referred to as BM case 2. Furthermore, temporal DL beam prediction may also be referred to as, for example, time-domain CSI prediction.

[0080] In addition, the beams associated with the output (prediction result) of the AI model can also be referred to as beam set A. The beams associated with the input of the AI model can also be referred to as beam set B.

[0081] In the present disclosure, set A may also correspond to a beam selected from the predicted beams. Resources used for set A may also be referred to as resources used for beam prediction, resources used for beam reporting, resources included in a CSI report, set A, resources of set A, a second (or first) set, second (or first) resources, etc.

[0082] In this disclosure, Set B may also correspond to the beam whose measurement results (for the AI model / function used for prediction) are used as input. Resources used for Set B may also be referred to as resources for beam measurement, resources used as input for beam prediction, Set B, resources of Set B, the first (or second) set, resources of the first (or second) set, etc.

[0083] Candidates for the input of the AI model for BM scenario 1 / 2 include L1-RSRP (reference signal received power in layer 1 (Layer 1 Reference Signal Received Power)), auxiliary information (for example, beam shape information, UE position / direction information, transmit beam usage information), channel impulse response (Channel Impulse Response (CIR)) information, corresponding DL transmit / receive beam ID, etc.

[0084] Candidates for the output of the AI model in 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 of each beam falling into the top K, the angles of these beams, and so on.

[0085] In addition to the candidates for the output of the AI model in BM case 1, the candidates for the output of the AI model in BM case 2 may include predicted beam failures.

[0086] (Data Collection)

[0087] In future wireless communication systems (eg, Rel. 18 and later), data collection for model training is being studied.

[0088] Two methods are being studied as methods for collecting measurement data on the UE side.

[0089] One is that the UE measures the data and performs calculations based on the measurements. When the UE determines the dataset to be used for training, it needs to request what kind of reference signal (RS) is expected.

[0090] Another scenario is that the UE receives data / measurements from other entities and performs calculations based on the data / measurements. In this case, new signaling optimized for the delivery of data / measurements is required.

[0091] Two methods are being studied as methods for collecting measurement data on the NW side.

[0092] One approach involves the base station measuring data and performing calculations based on these measurements. Existing specifications allow for the configuration of RSs for measurement by the UE. In this case, specific auxiliary information (e.g., UE configuration information) is considered useful to simplify data collection.

[0093] Another approach is for the base station to receive data / measurement values from other entities and perform data calculations based on the data / measurement values. In this case, new signaling optimized for the delivery of data / measurement values is required.

[0094] (DL RS request)

[0095] In the case of data collection on the UE side, research is underway to utilize DL RS requests in the collection of desired datasets for model training.

[0096] For example, we are researching auxiliary signaling and processes to simplify training data in AI / ML for positioning.

[0097] The auxiliary signaling may be, for example, a specific reference signal (e.g., a Positioning Reference Signal (PRS) or a sounding reference signal (Sounding Reference Signal (SRS)). The process may also utilize at least one of the configuration of the specific reference signal and the identifier of the configuration.

[0098] (Setting of measurement gap and PRS processing window)

[0099] As of Rel. 17, the UE may also request a measurement gap from measurement gaps pre-configured for positioning.

[0100] The request for the measurement gap can also be performed by following the steps MG1 to MG4 (refer to Figure 3 ).

[0101] The Location Management Function (LMF) may also request the gNB to pre-set one or more measurement gaps associated with the PRS information of the neighboring TRP (step MG1).

[0102] The UE may also be configured with one or more measurement gaps in advance by the base station (step MG2). The one or more measurement gaps may also be referred to as pre-configured measurement gap(s).

[0103] (If necessary,) the UE sends a MAC CE (positioning measurement gap activation / deactivation request) to the base station (step MG3). This MAC CE may also be a UL MAC CE, also called a positioning measurement gap activation / deactivation request MAC CE.

[0104] The LMF requests the base station to activate / deactivate the positioning measurement gap (step MG3 ′). Step MG3 ′ may also be performed at any timing.

[0105] After step MG3, the UE receives a MAC CE indicating the activation / deactivation of a positioning measurement gap from the base station (step MG4). This MAC CE may also be a DL MAC CE, also known as a positioning measurement gap activation / deactivation command MAC CE.

[0106] Figure 4A This is a diagram showing an example of a positioning measurement gap activation / deactivation request / indication MAC CE. Figure 4A The MAC CE includes a reserved bit field (denoted as "R"), a field indicating activation or deactivation of the positioning measurement gap (denoted as "A / D"), and a field indicating the identifier (ID) of the pre-configured positioning measurement gap (denoted as "Positioning MG ID").

[0107] The reserved bit may also be set to 0. Alternatively, when the field indicating activation or deactivation of the positioning measurement gap shows 1, it indicates that the MAC CE indicates activation; otherwise (when the field shows 0), it indicates that the MAC CE indicates deactivation.

[0108] The bit length of the field indicating the identifier (ID) of the preset positioning measurement gap may also be 4 bits.

[0109] UE can also use Figure 4AThe described positioning measurement gap activation / deactivation request MAC CE includes a field indicating an identifier (ID) of a pre-configured positioning measurement gap, to request activation / deactivation of the positioning measurement gap.

[0110] Base stations can also use Figure 4A The described positioning measurement gap activation / deactivation indication MAC CE includes a field indicating an identifier (ID) of a pre-configured positioning measurement gap, and indicates activation / deactivation of the positioning measurement gap.

[0111] In step MG2 , the UE receives information related to a pre-set positioning measurement gap (eg, RRC information element “PosGapConfig-r17”) using RRC signaling.

[0112] The information related to the pre-set positioning measurement gap may also be identified by a positioning measurement gap ID (eg, RRC information element “MeasPosPreConfigGapId-r17”).

[0113] The information related to the preset positioning measurement gap may also include at least one of the following information (refer to Figure 4B ) :

[0114] Positioning measurement gap ID (e.g., "MeasPosPreConfigGapId-r17").

[0115] Measure gap length (e.g., "mgl").

[0116] • The repetition period of the measurement gap (e.g., “mgrp”).

[0117] • The timing advance of the measurement gap (e.g., "mgta").

[0118] The gap offset (e.g., "gapOffset") for the gap pattern based on "mgrp".

[0119] The gap type (e.g., "gapType").

[0120] The measurement gap length, the measurement gap repetition period, and the measurement gap timing advance may also be expressed in ms.

[0121] The gap offset can also be expressed in the range of 0 to mgrp-1.

[0122] The gap type may also indicate any one of a measurement gap for each UE, a measurement gap for each FR1, and a measurement gap for each FR2.

[0123] As of Rel. 17, LMF can also activate a PRS Processing Window (PPW) from a PRS Processing Window (PPW) that is pre-set for positioning.

[0124] The activation of the PPW can also be performed by following the steps PW1 to PW3 (refer to Figure 5 ).

[0125] The LMF requests the base station to pre-set one or more PPWs associated with the PRS information of the adjacent TRP (step PW1).

[0126] The UE is configured with one or more PPWs in advance by the base station (step PW2). The one or more PPWs may also be referred to as pre-configured PPW(s).

[0127] After the LMF activates any one of the PPWs, the base station sends a MAC CE for activation / deactivation of the PPW (step PW3 ).

[0128] In addition, during activation / deactivation of the PPW, the UE does not make any request related to the pre-configured PPW.

[0129] In step PW3, the UE receives a MAC CE for PPW activation / deactivation, which may also be referred to as a PPW activation / deactivation command MAC CE.

[0130] Figure 6A This is a diagram showing an example of a PPW activation / deactivation indication MAC CE. Figure 6A The recorded MAC CE includes a reserved bit field (recorded as "R"), a field indicating activation or deactivation of PPW (recorded as "A / D"), a field indicating the number (N-1) of entries (octets) contained in the MAC CE (recorded as "numEntry"), a field related to the serving cell ID to which the MAC CE is applied (recorded as "Serving Cell ID"), and a field indicating the PPW ID (recorded as "PPWID").

[0131] The reserved bit may also be set to 0. Alternatively, when the field indicating activation or deactivation of the PPW shows 1, it indicates that the MAC CE indicates activation; otherwise (when the field shows 0), it indicates that the MAC CE indicates deactivation.

[0132] The bit length of the field indicating the number (N-1) of entries (octets) included in the MAC CE may be 2 bits. If this field indicates "00", N may be 2, and if it indicates "01", N may be 3. The same applies to the following.

[0133] The bit length of the field related to the serving cell ID to which the MAC CE is applied may also be 5 bits.

[0134] The bit length of the field representing the PPW ID may also be 2 bits. This field may also indicate the PPW configured in the active DL BWP in the serving cell identified by the field related to the serving cell ID. The ID (index) m represented by this field may also correspond to the (m+1)th entry in the list of PPW configurations in this BWP.

[0135] UE can also use Figure 6A The described PPW activation / deactivation indication MAC CE indicates activation / deactivation of the PPW by using a field indicating the PPW ID included in the PPW activation / deactivation indication MAC CE.

[0136] Base stations can also use Figure 6A The described PPW activation / deactivation indication MAC CE includes a field indicating the PPW ID to indicate activation / deactivation of the PPW.

[0137] In step PW2 , the UE receives information related to the pre-configured PPW using RRC signaling (eg, RRC information element “DL-PPW-PreConfig-r17”).

[0138] The information related to the pre-configured PPW may also be identified by a PPW ID (eg, RRC information element “DL-PPW-IDId-r17”).

[0139] The information related to the pre-set PPW may also include at least one of the following information (see Figure 6B ) :

[0140] PPW ID (for example, "dl-PPW-PreConfig-r17").

[0141] The period and offset of the PPW (e.g., “dl-PPW-Periodicity-and-StartSlot”).

[0142] • The length of the DL PPW in one or more time slots (eg, "length").

[0143] • Priority (eg, “priority”) between PDCCH / PDSCH / CSI-RS and PRS.

[0144] • The type of DL PPW (eg, "type").

[0145] (Prioritization and Type of PPW)

[0146] As of Rel. 17, the priorities involved in the reception of signals / channels in PPW are specified.

[0147] The UE is set with one of options 1 to 3 regarding the priority of the PPW according to the UE capability.

[0148] In option 1, one of two priority states is set / indicated via RRC signaling. In the first state, the PRS takes precedence over all other PDCCHs / PDSCHs / CSI-RSs. In the second state, all PDCCHs / PDSCHs / CSI-RSs take precedence over the PRS.

[0149] In option 2, one of three priority states is set or indicated via RRC signaling. In the first state, the PRS takes precedence over all other PDCCHs / PDSCHs / CSI-RSs. In the second state, the PDCCH / PDSCH used for URLLC (Ultra Reliable and Low Latency Communications) takes precedence over the PRS, while the CSI-RS / other PDSCHs take precedence over the PRS. In the third state, all PDCCHs / PDSCHs / CSI-RSs take precedence over the PRS.

[0150] In option 3, a priority state is defined / indicated. In option 3, the priority of PRS is higher than that of all other PDCCH / PDSCH / CSI-RS.

[0151] Regardless of which of 1 to 3 is selected, SSB has the highest priority.

[0152] In addition, as of Rel. 17, the types of PPW are specified.

[0153] PPW types are broadly classified into Type 1 (Type 1A and Type 1B) and Type 2.

[0154] The UE determines the granularity of discarding / receiving PRS (eg, window level or symbol level) based on the configured PPW type.

[0155] Type 1 (Type 1A and Type 1B) corresponds to the reception capability of PRS at the window level, and Type 2 corresponds to the reception capability of PRS at the symbol level.

[0156] In PPW type 1A, the discard rule is applied to all DL CCs. Specifically, in the case of the first state of option 1, PDCCH / PDSCH / CSI-RS other than PRS configured in the PPW within the DL BWP is discarded, and PDCCH / PDSCH / CSI-RS in the same time domain as the PPW in CCs other than the PPW CC are discarded (see Figure 7A as well as Figure 7B ).

[0157] In PPW type 1B, the discard rule is applied to a specific DL CC. Specifically, in the case of the first state of option 1, PDCCH / PDSCH / CSI-RS other than PRS configured in the PPW within the DL BWP is discarded, and PDCCH / PDSCH / CSI-RS in the same time domain as the PPW in CCs other than the PPW CC are not discarded and are received / decoded (refer to Figure 7C ).

[0158] In PPW type 2, the discard rule is applied within the PPW. Specifically, in the case of the first state of option 1, in the PPW within the DL BWP, the PDCCH / PDSCH / CSI-RS of the same symbol as the PRS is discarded, and in the PPW within the DL BWP, the PDCCH / PDSCH / CSI-RS of a different symbol from the PRS is received / decoded (refer to Figure 7D ).

[0159] (Research)

[0160] As mentioned above, research is underway on UE-side data collection and the request / receive operations for reference signals used for data collection. However, research on these specific operations is insufficient. In other words, research on the specific UE / NW operations when using downlink (DL) reference signals (RS) for UE-side data collection is insufficient.

[0161] Without sufficient research, data collection in the UE and the UE / NW operations involved in data collection cannot be properly defined. Consequently, it is impossible to achieve appropriate overhead reduction, high-precision channel estimation, and efficient resource utilization, potentially hindering improvements in communication throughput and quality.

[0162] Therefore, the inventors of the present invention have devised a method / operation for collecting data on the appropriate UE side. In addition, each embodiment of the present disclosure can also be applied without using AI (for example, it can also be applied when using a function for prediction).

[0163] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The wireless communication methods according to the respective embodiments may be applied individually or in combination.

[0164] In the present disclosure, "A / B" and "at least one of A and B" may be replaced with each other. In addition, in the present disclosure, "A / B / C" may also mean "at least one of A, B, and C."

[0165] In the present disclosure, the words “notify,” “activate,” “deactivate,” “indicate,” “select,” “configure,” “update,” and “determine” may be used interchangeably. In the present disclosure, the words “support,” “control,” “controllable,” “operate,” and “operable” may also be used interchangeably.

[0166] In this disclosure, Radio Resource Control (RRC), RRC parameters, RRC messages, higher-layer parameters, fields, Information Elements (IEs), and settings may also be overwritten. In this disclosure, Medium Access Control (MAC) Control Elements (CEs), update commands, and activation / deactivation commands may also be overwritten.

[0167] In the present disclosure, high-layer signaling may be, for example, Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, other messages (for example, positioning protocols (for example, NR Positioning Protocol A (NRPPa)) / LTE Positioning Protocol (LTE Positioning Protocol (LPP))) messages, etc.) or any one of them, or a combination thereof.

[0168] In the present disclosure, MAC signaling may include, for example, a MAC Control Element (MACCE) and a MAC Protocol Data Unit (PDU). Broadcast information may include, for example, a Master Information Block (MIB), a System Information Block (SIB), minimum system information (Remaining Minimum System Information (RMSI)), and other system information (Other System Information (OSI)).

[0169] In the present disclosure, the physical layer signaling may also be, for example, downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI)), etc.

[0170] In the present disclosure, ignore, discard, suspend, cancel, puncture, rate match, postpone, not send, etc. can also be rewritten to each other.

[0171] In this disclosure, the terms "setting information," "setting" (of certain information), and "set" (of certain information) may be overwritten. In this disclosure, "setting" refers to the collection of information referred to by "..." for ease of description and is not limited to this term.

The DL RS configuration for data collection is associated with a parameter ("requestID") representing the ID of the request related to data collection via the (pre-set) ID of the DL RS configuration for data collection ("DCRS-preconfigID" / "DCRSConfigID").

[0372] The data collection window configuration ("DCWinConfig") includes the (pre-set) data collection window configuration ID ("DCW-preconfigID" / "DCWinConfigID") and other information (for example, information related to priority rules ("priorityRule"). The data collection window configuration is linked to a parameter ("requestID") representing the ID of the request related to data collection via the (pre-set) data collection window configuration ID ("DCW-preconfigID" / "DCWinConfigID").

[0373] The measurement gap configuration ("measGapConfig") includes the (pre-set) measurement gap configuration ID ("measGapConfigID" / "MG-preConfigID") and other information (for example, information related to the priority rule, "priorityRule"). The measurement gap configuration is linked to a parameter ("requestID") indicating the ID of the request for data collection via the (pre-set) measurement gap configuration ID ("measGapConfigID" / "MG-preConfigID").

[0374] In addition, the above Figure 9 The names and structures of the information elements shown are just examples and are not limited to the examples shown.

[0375] According to the above second embodiment, it is possible to appropriately transmit a DL RS request.

[0376] <Third embodiment>

[0377] The third embodiment relates to DL RS measurements for data collection.

[0378] The third embodiment is roughly divided into Embodiments 3-1 to 3-5. UE / NW may also comply with at least one of Embodiments 3-1 to 3-5.

[0379] Implementation Method 3-1

[0380] The UE may also be configured / instructed to use a DL RS for data collection.

[0381] In the present disclosure, a DL RS for data collection, an RS for data collection, a DL RS associated with data collection, and a DC (data collection) RS may be overwritten with each other.

[0382] The UE / NW may also follow at least one of the following options 3-1-1 to 3-1-3.

[0383] [Select 3-1-1]

[0384] The UE may also be configured with higher layer parameters associated with the DC RS.

[0385] For example, the higher-layer parameter may be at least one of a CSI resource configuration (for data collection) ("CSI-ResourceConfig") and a PRS-related configuration (for data collection) ("NR-DL-PRS-PDC-Info").

[0386] The UE may also be configured with the (pre-configured) DL RS configuration ID included in the higher layer parameter.

[0387] The UE may also be configured with parameters included in the higher-layer parameters indicating whether they are pre-configured.

[0388] The UE may not be expected to be configured with a CSI-RS report, where a specific parameter of the CSI-RS report (e.g., a parameter indicating the reporting quantity ("reportQuantity")) is set to a specific value (e.g., 'none'). The UE may also not be configured with a CSI-RS report where a specific parameter (e.g., a parameter indicating the reporting quantity ("reportQuantity")) is set to a specific value (e.g., 'none'). With this configuration, the NW identifies the DC RS measured by the UE, and the UE does not need to report on the DC RS, thereby reducing signaling overhead.

[0389] The UE may also be configured with parameters indicating whether (pre-configured) DL RS settings / measurement gap settings / data collection window settings are activated / deactivated.

[0390] This parameter can also be expressed as a bit sequence, which indicates whether a pre-set setting is activated / deactivated.

[0391] [Select 3-1-2]

[0392] The UE may also receive an activation command (which may also be rewritten as a deactivation command) related to at least one of DL RS measurement, measurement gap, and data collection window.

[0393] The activation command may also be sent in accordance with at least one of the methods described in Supplement 2 below.

[0394] For example, the UE may also follow at least one of the methods described in the following Supplement 2 to receive an activation command for a preset setting.

[0395] For example, the UE may also follow at least one of the methods described in Supplement 2 below to receive an activation command including an ID indicating a DL RS measurement / measurement gap / data collection window.

[0396] The activation command may also include an ID for identifying the activation command.

[0397] The UE may also expect to measure the DL RS for data collection after a specific period (e.g., X symbols / slots / ms / subframes (X is an arbitrary number)) has passed since the HARQ-ACK (last symbol / slot) corresponding to the PDSCH (e.g., activation command) indicating the DL RS for data collection.

[0398] The X may be pre-defined in the specification, or may be notified / set / indicated to the UE using higher layer signaling (RRC / MAC CE) / DCI.

[0399] [Select 3-1-3]

[0400] The UE may also receive an acknowledgment signal (eg, positive acknowledgment / negative acknowledgment) corresponding to the requested DL RS request.

[0401] The UE may also follow at least one of the methods described in Supplement 2 below to receive an ID indicating DLRS request information approved / rejected by the NW.

[0402] At least two of the above options 3-1-1 to 3-1-3 may also be applied in combination.

[0403] According to Embodiment 3-1, it is possible to appropriately configure the DL RS for data collection.

[0404] Implementation Method 3-2

[0405] The UE may also be configured / instructed / activated to use measurement gaps for measurements for data collection.

[0406] The measurement gap may also be a measurement gap dedicated for data collection.

[0407] The measurement gap may also be a measurement gap associated with data collection.

[0408] This measurement gap may be a measurement gap shared with a measurement gap for other purposes (for example, a measurement gap for positioning).

[0409] The UE may also be expected to measure the DL RS used for data collection during the measurement gap. The UE may also be expected to measure the DL RS used for data collection during the measurement gap.

[0410] In the case where the measurement gap for data collection overlaps with other measurement gaps (eg, measurement gaps for positioning) (in the time / frequency domain), the UE may also follow at least one of the following options 3-2-1 to 3-2-3.

[0411] The UE can also prioritize other measurement gaps (Option 3-2-1). In other words, the UE can ignore the measurement gaps used for data collection. According to Option 3-2-1, since the measurement gaps used for data collection do not affect the current communication quality, they can be deprioritized.

[0412] The UE may not prioritize other measurement gaps (option 3-2-2). In other words, the UE may prioritize measurement gaps for data collection.

[0413] In the present disclosure, the UE may also assume that measurement gaps for data collection do not overlap (in time) with measurement gaps for other purposes (eg, positioning).

[0414] The UE may also determine whether other measurement gaps are prioritized or deprioritized based on the configuration of higher layer signaling (eg, RRC parameters) (option 3-2-3).

[0415] According to embodiment 3-2, it is possible to appropriately define the measurement gap configured / indicated / activated for the UE.

[0416] Implementation Method 3-3

[0417] The UE may also be configured / instructed / activated to have a window for data collection.

[0418] The UE may also be expected to measure a specific DL RS within a data collection window (for data collection). The UE may also be expected to measure a specific DL RS within a data collection window (for data collection).

[0419] The data collection window may also be associated with a specific DL RS. In this disclosure, this association may also be referred to as the type of the DL RS being measured.

[0420] The specific DL RS may be, for example, CSI-RS / SSB / PRS.

[0421] In the present disclosure, the data collection window, DL RS measurement / reception duration (for data collection), DCRS measurement / reception duration, DL RS measurement / reception opportunity (for data collection), DC RS measurement / reception opportunity, and PPW for data collection may be overwritten.

[0422] The UE may also be expected to measure a specific DL RS when specific conditions are met. The UE may also be expected to measure a specific DL RS when specific conditions are met.

[0423] The specific condition may also be at least one of a case where the specific DL RS is configured in an activated BWP and a case where the specific DL RS has the same parameter set (eg, subcarrier spacing setting) as that in a data collection window.

[0424] Even within the data collection window, the UE may not be expected to measure a specific DL RS. Even within the data collection window, the UE may not be expected to measure a specific DL RS.

[0425] The specific DL RS may be, for example, a DL RS from a non-serving cell or a DL RS from a serving cell that exceeds the capability of the UE.

[0426] According to Embodiment 3-3, the NW can determine the priority of the DL RS for data collection in each data collection window, and can also appropriately set the data collection window for the UE.

[0427] Implementation Method 3-4

[0428] It is also possible to specify (additional) priority rules for DL RSs associated with data collection.

[0429] The UE may also determine the priority rules for the DC RS and other signals / channels (eg, PDCCH / PDSCH / CSI-RS / SSB / PRS).

[0430] This determination may be made based on, for example, at least one of the following: rules specified in the specification, UE capabilities (reported UE capability information), and higher layer (RRC) parameter settings.

[0431] For example, priority rules based on the QCL relationship between DC RS and other signals / channels may also be specified / set.

[0432] For example, if the DL RS associated with data collection is QCLed with other signals / channels (e.g., PDCCH / PDSCH / CSI-RS / SSB / PRS) (e.g., in the same band / cell), the UE may also be expected to measure the DL RS.

[0433] For example, if the DL RS and other signals / channels associated with data collection (eg, PDCCH / PDSCH / CSI-RS / SSB / PRS) (eg, in the same band / cell) are set to QCL, the UE may also measure the DL RS.

[0434] When the DC RS and other RSs are of the same type, the UE may also determine that the DC RS has a lower / higher priority. For example, the UE may also determine the priority based on whether the RS is associated with data collection.

[0435] For example, the UE may determine that the CSI-RS associated with data collection has a lower (or higher) priority than the CSI-RS not associated with data collection.

[0436] Regardless of whether the DC RS and other RSs are of the same type, the UE can determine that the DC RS has a lower / higher priority. For example, the UE can also determine the priority based on the type of RS.

[0437] For example, the UE may determine that the SSB associated with data collection has a lower (or higher) priority than the CSI-RS not associated with data collection.

[0438] Priority rules can also be determined per data collection window / per UE.

[0439] Priority rules may also be determined for each DL RS configuration. For example, the DL RS configuration may include at least one of a CSI resource configuration (for data collection) (e.g., "CSI-ResourceConfig") and a PRS-related configuration (for data collection) (e.g., "NR-DL-PRS-PDC-Info").

[0440] In the case where the UE is expected to measure the DC RS and the DC RS is a higher / lower priority than other channels / signals, the UE may also follow at least one of the following options 3-4-1 and 3-4-2.

[0441] [Select 3-4-1]

[0442] If a higher priority signal / channel overlaps with the time domain (e.g., symbol) of a lower priority signal / channel, the UE may not be expected to measure the lower priority signal / channel. If a higher priority signal / channel overlaps with the time domain (e.g., symbol) of a lower priority signal / channel, the UE may not be expected to measure the lower priority signal / channel.

[0443] [Select 3-4-2]

[0444] If a higher-priority signal / channel overlaps with the time domain (e.g., symbol) of a lower-priority signal / channel, the UE may not be expected to measure the lower-priority signal / channel in the same band / cell / CC as the higher-priority channel / signal. If a higher-priority signal / channel overlaps with the time domain (e.g., symbol) of a lower-priority signal / channel, the UE may not be expected to measure the lower-priority signal / channel in the same band / cell / CC as the higher-priority channel / signal.

[0445] The above options 3-4-1 and 3-4-2 may also be determined based on at least one of the RRC configuration, the reported UE capability information, and a rule predefined in the specification.

[0446] According to Embodiment 3-4, even when a plurality of signals / channels overlap, the processing operation of the UE can be appropriately performed based on the priority.

[0447] Implementation Methods 3-5

[0448] Multiple types of data collection windows may be specified, and the type may correspond to any of the following options 3-5-1 to 3-5-4.

[0449] When the UE is expected to measure the DC RS within the data collection window, and the DC RS within the data collection window has a higher / lower priority than other channels / signals, the UE may also follow at least one of the following options 3-5-1 and 3-5-4.

[0450] [Select 3-5-1]

[0451] The UE may not be expected to measure lower priority signals / channels within the data collection window. The UE may not be expected to measure lower priority signals / channels within the data collection window.

[0452] [Select 3-5-2]

[0453] The UE may not be expected to measure lower priority signals / channels in the same band / cell / CC as the higher priority channel / signal. The UE may not measure lower priority signals / channels in the same band / cell / CC as the higher priority channel / signal.

[0454] [Select 3-5-3]

[0455] The UE may also not be expected to measure the lower priority signal / channel (within the data collection window) in the case where the higher priority signal / channel overlaps the time domain (eg, symbol) of the lower priority signal / channel.

[0456] In the case where a higher priority signal / channel overlaps with the time domain (eg, symbol) of a lower priority signal / channel, the UE may not measure the lower priority signal / channel (within the data collection window).

[0457] The UE may also not be expected to measure the lower priority signal / channel (within the data collection window) when the higher priority signal / channel overlaps with the time domain (e.g., codeword) of the lower priority signal / channel, and the source RS of the QCL of the lower priority signal / channel is different from the source RS of the QCL of the higher priority signal / channel.

[0458] The UE may also not measure the lower priority signal / channel (within the data collection window) when a higher priority signal / channel overlaps with the time domain (e.g., codeword) of a lower priority signal / channel, and the source RS of the QCL of the lower priority signal / channel is different from the source RS of the QCL of the higher priority signal / channel.

[0459] [Select 3-5-4]

[0460] In the same band / cell / CC, when a higher priority signal / channel overlaps with a lower priority signal / channel in the time domain (e.g., symbol), the UE may not be expected to measure the lower priority signal / channel (within the data collection window).

[0461] In the same band / cell / CC, when a higher priority signal / channel overlaps with a lower priority signal / channel in the time domain (e.g., symbol), the UE may not measure the lower priority signal / channel (within the data collection window).

[0462] In the same band / cell / CC, when a higher priority signal / channel overlaps with the time domain (e.g., symbol) of a lower priority signal / channel, and the source RS of the QCL of the lower priority signal / channel is different from the source RS of the QCL of the higher priority signal / channel, the UE may not be expected to measure the lower priority signal / channel (within the data collection window).

[0463] In the same band / cell / CC, if a higher priority signal / channel overlaps with the time domain (e.g., symbol) of a lower priority signal / channel, and the source RS of the QCL of the lower priority signal / channel is different from the source RS of the QCL of the higher priority signal / channel, the UE may not measure the lower priority signal / channel (within the data collection window).

[0464] The above options 3-5-1 to 3-5-4 may also be determined based on at least one of the RRC settings, the reported UE capability information, and rules predefined in the specification.

[0465] According to Embodiment 3-5, it is possible to appropriately perform reception processing of signals / channels of UEs within the data collection window.

[0466] According to the third embodiment described above, DL RS measurement for data collection can be appropriately performed.

[0467] <Fourth embodiment>

[0468] The fourth embodiment relates to the termination of DL RS measurements for data collection.

[0469] The fourth embodiment is roughly divided into Embodiments 4-1 to 4-4. UE / NW may also comply with at least one of Embodiments 4-1 to 4-4.

[0470] Implementation Method 4-1

[0471] The UE may also send a deactivation command associated with DL RS measurement / measurement gap / data collection window for data collection.

[0472] For example, the sending may be performed according to the method described in Supplement 3 below.

[0473] The deactivation command may also include a parameter indicating at least one of the following:

[0474] ID indicating activation (activation command);

[0475] ID indicating DL RS request information;

[0476] The ID of the DL RS associated with the data collection;

[0477] ID indicating DL RS settings / measurement gap / data collection window.

[0478] For example, after a specific period (e.g., X symbols / slots / ms / subframes (X is an arbitrary number)) has passed since reception of a specific PDCCH, the UE may not be expected to measure the DL RS and configure at least one of a measurement gap / data collection window.

[0479] For example, after a specific period (e.g., X symbols / slots / ms / subframes (X is an arbitrary number)) has passed since reception of a specific PDCCH, the UE may not expect at least one of DL RS measurement and measurement gap / data collection window configuration.

[0480] The X may be pre-defined in the specification, or may be notified / set / indicated to the UE using higher layer signaling (RRC / MAC CE) / DCI.

[0481] The specific PDCCH may be, for example, a PDCCH associated with a DCI format that schedules PUSCH transmission having the same HARQ process number as the deactivation command and has a toggled New Data Indicator (NDI) field value.

[0482] According to Embodiment 4-1, it is possible to appropriately terminate DL RS measurement for data collection by UE.

[0483] Implementation Method 4-2

[0484] The UE may also request the NW to send a deactivation command associated with DL RS measurement / measurement gap / data collection window for data collection.

[0485] For example, the request may be sent in accordance with at least one of the methods described in Supplement 3 below.

[0486] The request may also include a parameter indicating at least one of the following:

[0487] ID indicating activation (activation command);

[0488] ID indicating DL RS request information;

[0489] The ID of the DL RS associated with the data collection;

[0491] The NW that receives the request may also determine whether to deactivate DL RS measurement / measurement gap / data collection window for data collection.

[0492] According to Embodiment 4-2, it is possible to appropriately terminate DL RS measurement for data collection by UE / NW.

[0493] Implementation Method 4-3

[0494] The UE may also receive a deactivation command for DL RS measurement.

[0495] For example, the deactivation command may also be sent according to at least one of the methods described in Supplement 2 below.

[0496] For example, the UE may also follow at least one method described in the following supplement 2 to receive a deactivation command for a preset setting (the setting described in the first embodiment).

[0497] The deactivation command may also include an ID that identifies the deactivation command.

[0498] After a specific period (e.g., X symbols / slots / ms / subframes (X is an arbitrary number)) from the transmission of a specific channel / signal (the last symbol / slot), the UE may not be expected to measure the DL RS and configure at least one of the measurement gap / data collection window.

[0499] After a specific period (e.g., X symbols / slots / ms / subframes (X is an arbitrary number)) has passed since the transmission of a specific channel / signal (the last symbol / slot), the UE may not expect at least one of the DL RS measurement and the configuration of the measurement gap / data collection window.

[0500] The specific channel / signal may be, for example, the HARQ-ACK corresponding to the PDSCH indicating the deactivation command.

[0501] The X may be pre-defined in the specification, or may be notified / set / indicated to the UE using higher layer signaling (RRC / MAC CE) / DCI.

[0502] Implementation 4-3 may also be applied in combination with the above-mentioned implementation 4-2.

[0503] According to Embodiment 4-3, it is possible to appropriately terminate DL RS measurement for data collection by the NW.

[0504] Implementation Method 4-4

[0505] After a specific period has passed since a specific timing, the UE may deactivate DL RS measurement / measurement gap / data collection window for data collection.

[0506] The specific period may be pre-specified in the specification, or may be indicated / set to the UE from the base station in accordance with at least one of the methods described in Supplement 2 below.

[0507] This specific timing may be pre-defined in the specification, or may be indicated / configured to the UE from the base station according to at least one of the methods described in Supplement 2. For example, this specific timing may be the timing when the UE activates DL RS measurement / measurement gap / data collection window for data collection.

[0508] According to Embodiment 4-4, DL RS measurement for data collection can be appropriately terminated.

[0509] According to the fourth embodiment described above, the end of DL RS measurement for data collection can be appropriately controlled.

[0579] The BS reconstructs the received coded bits as input to the decoder's AI model and outputs the CSI / channel matrix / precoding matrix.

The AI model information in this disclosure may also include an AI model index in addition to or in place of the aforementioned AI model input / output information, etc. The association between the AI model index and AI model information (e.g., AI model input / output information) may be pre-defined in the standard or notified to the UE from the NW.

[0586] The AI model information in this disclosure may also be associated with an AI model and may also be referred to as AI model-related information (or simply as "related information"). Information used to identify the AI model may not be explicitly included in the AI model-related information. For example, the AI model-related information may include only metadata.

[0587] In the present disclosure, the model ID may be replaced with the ID corresponding to the set of AI models (model set ID).

For example, meta-information (or meta-information ID) may be used by the UE to select an AI model based on which beam the BS is using, or by the UE to notify the BS which beam to use in order to apply a deployed AI model. In addition, in the present disclosure, the meta-information ID may be replaced with the ID corresponding to the set of meta-information (meta-information set ID).

[0635] (Wireless Communication System)

[0636] The following describes a configuration of a wireless communication system according to an embodiment of the present disclosure. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above-described embodiments of the present disclosure or a combination thereof.

[0637] Figure 10 This figure shows an example of a schematic configuration of a wireless communication system according to one embodiment. Wireless communication system 1 (may also be referred to simply as system 1) may be a system that implements communication using Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the fifth-generation mobile communication system New Radio (5GNR), or the like.

[0638] In addition, the wireless communication system 1 may also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple radio access technologies (Radio Access Technologies (RATs)). MR-DC may also 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)), and the like.

[0639] In EN-DC, the LTE (E-UTRA) base station (eNB) is the Master Node (MN), and the NR base station (gNB) is the 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.

[0640] The wireless communication system 1 may also support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity (NR-NR Dual Connectivity (NN-DC)) in which both the MN and the SN are NR base stations (gNB)).

[0641] The wireless communication system 1 may also include a base station 11 that forms a macrocell C1 with relatively wide coverage, and base stations 12 (12a-12c) that are deployed within the macrocell C1 and form small cells C2 that are narrower than the macrocell C1. User terminals 20 may also be located within at least one of the cells. The arrangement and number of cells and user terminals 20 are not limited to those shown in the figure. Hereinafter, when not distinguishing between base stations 11 and 12, they are collectively referred to as base stations 10.

[0642] 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).

[0643] 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)). Macrocell C1 may be included in FR1, and small cell C2 may be included in FR2. For example, FR1 may be a frequency band below 6 GHz (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). The frequency bands and definitions of FR1 and FR2 are not limited to these. For example, FR1 may correspond to a frequency band higher than FR2.

[0644] 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.

[0645] Multiple base stations 10 may be connected via wired (e.g., optical fiber based on the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wireless (e.g., NR communication). For example, when NR communication is used as a backhaul between base stations 11 and 12, base station 11, which functions as a host station, may be referred to as an Integrated Access Backhaul (IAB) donor, and base station 12, which functions as a relay station (relay), may be referred to as an IAB node.

[0646] The base station 10 may be connected to the core network 30 via other base stations 10 or directly. The core network 30 may include, for example, at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0647] The core network 30 may also include, for example, network functions (NFs), such as the User Plane Function (UPF), Access and Mobility Management Function (AMF), Session Management Function (SMF), Unified Data Management (UDM), Application Function (AF), Data Network (DN), Location Management Function (LMF), and Operation, Administration and Maintenance (OAM). Furthermore, multiple functions may be provided by a single network node. Furthermore, communication with an external network (e.g., the Internet) may be performed via the DN.

[0648] The user terminal 20 may also be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0649] In the wireless communication system 1 , a radio access scheme based on orthogonal frequency division multiplexing (OFDM) may be used. For example, in at least one of the downlink (DL) and uplink (UL), cyclic prefix OFDM (CP-OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), orthogonal frequency division multiple access (OFDMA), or single carrier frequency division multiple access (SC-FDMA) may be used.

[0650] The radio access scheme may also be referred to as a waveform. In addition, in the wireless communication system 1 , other radio access schemes (eg, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0651] As downlink channels, the wireless communication system 1 may use a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20 , a broadcast channel (Physical Broadcast Channel (PBCH)), a downlink control channel (Physical Downlink Control Channel (PDCCH)), etc.

[0652] In addition, as uplink channels, the wireless communication system 1 can also use an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20, an uplink control channel (Physical Uplink Control Channel (PUCCH)), a random access channel (Physical Random Access Channel (PRACH)), etc.

[0653] User data, higher-layer control information, and system information blocks (SIBs) are transmitted via the PDSCH. User data and higher-layer control information can also be transmitted via the PUSCH. Furthermore, the Master Information Block (MIB) can also be transmitted via the PBCH.

[0654] The lower layer control information may also be transmitted via the PDCCH. The lower layer control information may include, for example, downlink control information (Downlink Control Information (DCI)) including scheduling information for at least one of the PDSCH and the PUSCH.

[0655] In addition, the DCI that schedules the PDSCH may also be referred to as DL allocation, DL DCI, etc., and the DCI that schedules the PUSCH may also be referred to as UL grant, UL DCI, etc. In addition, the PDSCH may also be rewritten as DL data, and the PUSCH may also be rewritten as UL data.

[0656] PDCCH detection also utilizes a control resource set (CORESET) and a search space. A CORESET corresponds to the resources for searching for DCI. A search space corresponds to the search area and search method for PDCCH candidates. A CORESET can be associated with one or more search spaces. The UE can also monitor the CORESET associated with a search space based on the search space configuration.

[0657] A search space may also correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may also be referred to as a search space set. Furthermore, the terms "search space," "search space set," "search space setting," "search space set setting," "CORESET," and "CORESET setting" in this disclosure may be interchangeable.

[0658] The PUCCH can also transmit uplink control information (uplink control information (UCI)) including at least one of channel state information (CSI), delivery confirmation information (e.g., also known as hybrid automatic repeat request ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH can also transmit the random access preamble used to establish a connection with a cell.

[0659] In the present disclosure, downlink, uplink, etc. may be expressed without the word “link.” Furthermore, various channels may be expressed without the word “physical” at the beginning.

[0660] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), and the like may also be transmitted. As DL-RSs, in the wireless communication system 1, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), and a phase tracking reference signal (PTRS) may also be transmitted.

[0661] For example, a synchronization signal may be at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). A signal block containing SSs (PSS, SSS) and PBCHs (and DMRS for the PBCH) may also be referred to as an SS / PBCH block or an SS block (SSB). Furthermore, SSs and SSBs may also be referred to as reference signals.

[0662] In addition, wireless communication system 1 may also transmit a sounding reference signal (SRS) or a demodulation reference signal (DMRS) as an uplink reference signal (UL-RS). DMRS is also called a user terminal-specific reference signal (UE-specific Reference Signal).

The user terminal 20 includes a control unit 210, a transmitting / receiving unit 220, and a transmitting / receiving antenna 230. Furthermore, the control unit 210, the transmitting / receiving unit 220, and the transmitting / receiving antenna 230 may each be provided in one or more units.

[0685] In addition, in this example, the functional blocks of the characteristic parts of this embodiment are mainly shown, and it is also assumed that the user terminal 20 also has other functional blocks required for wireless communication. Part of the processing of each unit described below may also be omitted.

[0686] The control unit 210 controls the entire user terminal 20. The control unit 210 can be composed of a controller, a control circuit, and the like that are described based on common knowledge in the technical field to which this disclosure relates.

[0687] The control unit 210 may also control signal generation, mapping, etc. The control unit 210 may also control transmission, reception, measurement, etc. using the transmission and reception unit 220 and the transmission and reception antenna 230.

The measuring unit 223 may also measure received power (e.g., RSRP), received quality (e.g., RSRQ, SINR, SNR), signal strength (e.g., RSSI), propagation path information (e.g., CSI), and the like. The measurement results may also be output to the control unit 210.

[0700] In addition, the measurement unit 223 may also derive channel measurements for CSI calculation based on channel measurement resources. Channel measurement resources may also be, for example, non-zero power (NZP) CSI-RS resources. In addition, the measurement unit 223 may also derive interference measurements for CSI calculation based on interference measurement resources. Interference measurement resources may also be at least one of NZP CSI-RS resources for interference measurement, CSI-Interference Measurement (IM) resources, etc. In addition, CSI-IM may also be referred to as CSI-Interference Management (IM) and may be interchangeable with Zero Power (ZP) CSI-RS.

[0701] In addition, the transmitting unit and the receiving unit of the user terminal 20 in the present disclosure may also be composed of at least one of the transmitting and receiving unit 220 and the transmitting and receiving antenna 230 .

[0710] (Hardware structure)

[0711] Furthermore, the block diagrams used in the description of the above embodiments illustrate blocks of functional units. These functional blocks (structural units) are implemented by any combination of at least one of hardware and software. Furthermore, the implementation method of each functional block is not particularly limited. Specifically, each functional block can be implemented using a single device that is physically or logically combined, or by connecting two or more physically or logically separate devices directly or indirectly (e.g., by wired or wireless connections) to implement these multiple devices. A functional block can also be implemented by combining one or more of these devices with software.

[0712] Here, the term "function" includes, but is not limited to, judging, determining, calculating, calculating, processing, deriving, investigating, searching, confirming, receiving, sending, outputting, accessing, resolving, selecting, choosing, establishing, comparing, assuming, expecting, regarding, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assigning. For example, a functional block (structural unit) that implements a transmitting function may also be referred to as a transmitting unit, a transmitter, or the like. Any of these terms are as described above, and their implementation methods are not particularly limited.

[0713] For example, a base station, a user terminal, etc. in one embodiment of the present disclosure may also function as a computer that performs processing of the wireless communication method of the present disclosure. Figure 13 This figure shows an example of the hardware configuration of a base station and a user terminal according to one embodiment. The base station 10 and user terminal 20 described above can also be physically configured as a computer device including a processor 1001, a memory 1002, a storage 1003, a communication device 1004, an input device 1005, an output device 1006, and a bus 1007.

[0714] In this disclosure, the terms "device," "circuit," "equipment," "section," and "unit" are interchangeable. The hardware configuration of the base station 10 and the user terminal 20 may include one or more of the devices shown in the figures, or may exclude some of the devices.

[0715] For example, although only one processor 1001 is shown, multiple processors may be provided. Furthermore, processing may be performed by a single processor, or by two or more processors simultaneously, sequentially, or using other methods. Furthermore, processor 1001 may be implemented using more than one chip.

[0716] The functions of the base station 10 and the user terminal 20 are realized, for example, by reading specific software (program) into hardware such as the processor 1001 and the memory 1002, so that the processor 1001 performs calculations and controls communication via the communication device 1004, or by controlling at least one of the reading and writing of data in the memory 1002 and the storage 1003.

[0717] Processor 1001 controls the entire computer by, for example, operating an operating system. Processor 1001 may also be comprised of a central processing unit (CPU) including interfaces with peripheral devices, a control device, a computing device, registers, and the like. For example, at least a portion of the aforementioned control unit 110 (210) and transceiver unit 120 (220) may also be implemented by processor 1001.

[0718] Furthermore, the processor 1001 reads programs (program code), software modules, data, etc. from at least one of the storage 1003 and the communication device 1004 into the memory 1002 and executes various processes based on these programs. As a program, a program that causes a computer to execute at least a portion of the operations described in the above embodiments can be used. For example, the control unit 110 (210) can also be implemented by a control program stored in the memory 1002 and executed by the processor 1001, and the other functional blocks can also be implemented similarly.

[0719] Memory 1002 may also be a computer-readable recording medium, such as at least one of a read-only memory (ROM), an erasable programmable ROM (EPROM), an electrically erasable programmable ROM (EEPROM), a random access memory (RAM), or other suitable storage medium. Memory 1002 may also be referred to as a register, a cache, a main memory (main storage device), or the like. Memory 1002 can store executable programs (program code), software modules, and the like for implementing the wireless communication method according to an embodiment of the present disclosure.

[0720] Storage 1003 may also be a computer-readable recording medium, such as at least one of a flexible disk, a floppy disk, an optical disk (such as a compact disk (Compact Disc ROM (CD-ROM))), a digital versatile disk, a Blu-ray disk), a removable disk, a hard disk drive, a smart card, a flash memory device (such as a card, stick, or key drive), a magnetic stripe, a database, a server, or other suitable storage medium. Storage 1003 may also be referred to as an auxiliary storage device.

[0721] The communication device 1004 is hardware (a transmitting and receiving device) for communicating between computers via at least one of a wired network and a wireless network. For example, it is also referred to as a network device, a network controller, a network card, a communication module, etc. In order to implement at least one of frequency division duplex (FDD) and time division duplex (TDD), the communication device 1004 may also be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. For example, the aforementioned transmitting and receiving unit 120 (220) and the transmitting and receiving antenna 130 (230) may also be implemented by the communication device 1004. The transmitting and receiving unit 120 (220) may also be implemented by a transmitting unit 120a (220a) and a receiving unit 120b (220b) that are physically or logically separated.

[0722] The input device 1005 is an input device that receives input from the outside (e.g., a keyboard, mouse, microphone, switch, button, sensor, etc.). The output device 1006 is an output device that outputs to the outside (e.g., a display, speaker, light-emitting diode (LED) lamp, etc.). Alternatively, the input device 1005 and output device 1006 may be integrated (e.g., a touch panel).

[0723] Furthermore, the processor 1001, memory 1002, and other devices are connected via a bus 1007 for communicating information. The bus 1007 may be configured as a single bus or may be configured as different buses between the devices.

[0724] Furthermore, the base station 10 and user terminal 20 may also be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field programmable gate array (FPGA), and may use this hardware to implement part or all of each functional block. For example, the processor 1001 may be implemented using at least one of these hardware components.

[0725] (Variation)

[0726] In addition, the terms described in this disclosure and the terms required for understanding this disclosure may be replaced with terms having the same or similar meanings. For example, channel, symbol, and signal (signal or signaling) may be replaced with each other. In addition, a signal may also be a message. Reference Signal (RS) may also be referred to as RS, and may also be referred to as Pilot, Pilot Signal, etc. depending on the applied standard. In addition, Component Carrier (CC) may also be referred to as Cell, Frequency Carrier, Carrier Frequency, etc.

[0727] A radio frame can also be composed of one or more time periods (frames) in the time domain. Each of these one or more time periods (frames) that make up a radio frame can also be called a subframe. Furthermore, a subframe can also be composed of one or more time slots in the time domain. A subframe can also be a fixed time length (for example, 1ms) that is independent of the numerology.

[0728] Here, a parameter set may also refer to communication parameters applied to at least one of the transmission and reception of a signal or channel. For example, the parameter set may also represent at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, radio frame structure, specific filtering processing performed by the transmitter and receiver in the frequency domain, and specific windowing processing performed by the transmitter and receiver in the time domain.

[0729] In the time domain, a slot can also be composed of one or more symbols (Orthogonal Frequency Division Multiplexing (OFDM) symbols, Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, etc.) Furthermore, a slot can also be a time unit based on a parameter set.

[0730] A time slot may also contain multiple mini-slots. Each mini-slot may also consist of one or more symbols in the time domain. Furthermore, a mini-slot may also be referred to as a sub-slot. A mini-slot may also consist of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using mini-slots may also be referred to as PDSCH (PUSCH) mapping type B.

[0731] Radio frames, subframes, time slots, mini-slots, and symbols all represent time units used for signal transmission. Radio frames, subframes, time slots, mini-slots, and symbols may also be referred to by their respective equivalents. Furthermore, the time units of frame, subframe, time slot, mini-slot, and symbol in this disclosure may be interchangeable.

[0732] For example, a subframe can be called a TTI, multiple consecutive subframes can be called a TTI, and a slot or a mini-slot can be called a TTI. That is, at least one of a subframe and a TTI can 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. Furthermore, the unit representing a TTI can be called a slot, a mini-slot, or the like, rather than a subframe.

[0733] Here, TTI refers to, for example, the minimum time unit used for scheduling in wireless communications. For example, in the LTE system, a base station schedules each user terminal by allocating radio resources (such as the frequency bandwidth and transmit power available to each user terminal) in TTI units. The definition of TTI is not limited to this.

[0734] A TTI can also be a unit of time for transmitting channel-coded data packets (transport blocks), code blocks, code words, etc., and can also be a unit of processing for scheduling, link adaptation, etc. Furthermore, when a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, code block, code word, etc. is actually mapped can be shorter than the TTI.

[0735] Furthermore, while a time slot or mini-slot is referred to as a TTI, one or more TTIs (i.e., one or more time slots or one or more mini-slots) can also be the minimum time unit for scheduling. Furthermore, the number of time slots (mini-slots) that constitute this minimum time unit for scheduling can also be controlled.

[0736] A TTI having a time length of 1 ms may also be referred to as a normal TTI (TTI in 3GPP Rel.8-12), a standard TTI, a long TTI, a normal subframe, a standard subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI may also be referred to as a shortened TTI, a short TTI, a partial TTI (partial or fractional TTI), a shortened subframe, a short subframe, a mini-slot, a subslot, a time slot, etc.

[0737] In addition, a long TTI (e.g., normal TTI, subframe, etc.) can also be rewritten as a TTI with a time length exceeding 1ms, and a short TTI (e.g., shortened TTI, etc.) can also be rewritten as a TTI with a TTI length shorter than the long TTI and longer than 1ms.

[0738] A resource block (RB) is a unit of resource allocation in the time and frequency domains. In the frequency domain, it may also include one or more consecutive subcarriers (subcarriers). The number of subcarriers contained in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers contained in an RB can also be determined based on the parameter set.

[0739] In addition, an RB may also include one or more symbols in the time domain, and may also be the length of a slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks.

[0740] In addition, one or more RBs may also be referred to as a physical resource block (Physical RB (PRB)), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0741] 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.

[0742] A Bandwidth Part (BWP) (also known as a fractional bandwidth) can also represent a subset of contiguous common resource blocks (RBs) used for a particular parameter set within a carrier. Common RBs can also be identified by their index relative to the common reference point for that carrier. PRBs can also be defined within a BWP and numbered within that BWP.

[0743] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). For a UE, one or more BWPs may be configured within one carrier.

[0744] At least one of the configured BWPs may be activated, and the UE may not assume that it will transmit or receive specific signals / channels outside the activated BWP.

[0745] The above-mentioned structures of radio frames, subframes, slots, mini-slots, and symbols are merely examples. For example, the number of subframes in a radio frame, the number of slots per subframe or radio frame, the number of mini-slots within a slot, the number of symbols and RBs within a slot or mini-slot, the number of subcarriers within an RB, the number of symbols within a TTI, the symbol length, and the cyclic prefix (CP) length can be varied in various ways.

[0746] Furthermore, the information and parameters described in this disclosure may be expressed as absolute values, relative values relative to a specific value, or other corresponding information. For example, wireless resources may be indicated by specific indexes.

[0747] The names used for parameters, etc. in this disclosure are not intended to be limiting in any respect. Furthermore, the mathematical formulas used for these parameters may differ from those explicitly disclosed in this disclosure. Various channels (such as PUCCH and PDCCH) and information elements can 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 respect.

[0748] Information, signals, and the like described in this disclosure may also be represented using any of a variety of different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, and the like that may be referred to throughout the foregoing description may also be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or photons, or any combination thereof.

[0749] Furthermore, information, signals, etc. can be output in at least one of the following directions: from a higher layer (upper layer) to a lower layer (lower layer), and from a lower layer to a higher layer. Information, signals, etc. can also be input and output via multiple network nodes.

[0750] Input and output information, signals, etc. can be stored in a specific location (e.g., memory) or managed using a management table. Input and output information, signals, etc. can be overwritten, updated, or appended. Output information, signals, etc. can also be deleted. Input information, signals, etc. can also be sent to other devices.

[0751] The notification of information is not limited to the methods / implementations described in this disclosure and may also be performed using other methods. For example, the notification of information in this disclosure may also be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI))), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB)), System Information Block (SIB), etc.), Medium Access Control (MAC) signaling), other signals, or a combination thereof.

[0752] In addition, physical layer signaling may also be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), Layer 1 control information (L1 control signal), etc. Furthermore, RRC signaling may also be referred to as an RRC message, such as an RRC Connection Setup message or an RRC Connection Reconfiguration message. Furthermore, MAC signaling may also be notified using, for example, a MAC Control Element (CE).

[0753] Furthermore, notification of specific information (eg, notification of “it is X”) is not limited to explicit notification, but may be performed implicitly (eg, by not notifying the specific information or by notifying other information).

[0754] The determination can be made using a value represented by a bit (0 or 1), a true or false value represented by true (true) or false (false) (Boolean value), or by comparing numerical values (for example, comparing with a specific value).

[0755] The term “software” or “firmware” shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, sub-programs, software modules, applications, software applications, software packages, routines, sub-routines, objects, executable files, execution threads, procedures, functions, etc.

[0756] Furthermore, software, instructions, information, and the like may also be transmitted and received via a transmission medium. For example, if the software is transmitted from a website, server, or other remote source using at least one of a wired technology (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and a wireless technology (infrared, microwave, etc.), at least one of the wired technology and the wireless technology is included within the definition of a transmission medium.

[0757] The terms "system" and "network" used in this disclosure are interchangeable. "Network" may also refer to devices included in the network (eg, base stations).

[0758] In the present disclosure, terms such as "precoding", "precoder", "weight (precoding weight)", "Quasi-Co-Location (QCL))", "Transmission Configuration Indication state (TCI state)", "spatial relation", "spatial domain filter", "transmit power", "phase rotation", "antenna port", "layer", "number of layers", "rank", "resource", "resource set", "beam", "beam width", "beam angle", "antenna", "antenna element", "panel", "UE panel", "transmitting entity", and "receiving entity" can be used interchangeably.

[0759] Furthermore, in the present disclosure, antenna ports can be interchanged with antenna ports used for any signal / channel (e.g., Demodulation Reference Signal (DMRS) ports). In the present disclosure, resources can be interchanged with resources used for any signal / channel (e.g., reference signal resources, SRS resources, etc.). Furthermore, resources can include time / frequency / space / power resources. Furthermore, a spatial domain transmit filter can include at least one of a spatial domain transmission filter and a spatial domain reception filter.

[0760] The above-mentioned group may also include, for example, at least one of a spatial relationship group, a code division multiplexing (CDM) group, a reference signal (RS) group, a control resource set (CORESET) group, a PUCCH group, an antenna port group (for example, a DMRS port group), a layer group, a resource group, a beam group, an antenna group, a panel group, etc.

[0761] In addition, in the present disclosure, beam, SRS Resource Indicator (SRI), CORESET, CORESET pool, PDSCH, PUSCH, codeword (CW), transport block (TB), RS, etc. can also be rewritten.

In some cases, a base station may be referred to as a macrocell, small cell, femtocell, or picocell.

[0767] A base station can accommodate one or more (for example, three) cells. When a base station accommodates multiple cells, the base station's overall coverage area can be divided into multiple smaller areas, each of which can be provided with communications services by a base station subsystem (for example, a small indoor base station (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a portion or the entire coverage area of at least one of a base station and a base station subsystem providing communications services within that coverage area.

[0768] In the present disclosure, the matter of a base station sending information to a terminal may be replaced with the matter of the base station instructing the terminal to control / operate based on the information.

[0769] In the present disclosure, terms such as “mobile station (MS)”, “user terminal”, “user device (UE)”, and “terminal” can be used interchangeably.

[0781] The communication module 60 can communicate with the microprocessor 61 and components of the vehicle 40 via the communication port 63. For example, the communication module 60 transmits and receives data (information) via the communication port 63 with the drive unit 41, steering unit 42, accelerator pedal 43, brake pedal 44, shift lever 45, left and right front wheels 46, left and right rear wheels 47, axle 48, microprocessor 61 and memory (ROM, RAM) 62 within the electronic control unit 49, and various sensors 50-58 included in the vehicle 40.

[0782] The communication module 60 is controlled by the microprocessor 61 of the electronic control unit 49 and is a communication device capable of communicating with external devices. For example, various information can be transmitted and received with the external device via wireless communication. The communication module 60 can be located either inside or outside the electronic control unit 49. Examples of external devices include the aforementioned base station 10 and user terminal 20. Furthermore, the communication module 60 can also be, for example, at least one of the aforementioned base station 10 and user terminal 20 (and can function as at least one of the base station 10 and user terminal 20).

[0783] The communication module 60 may also transmit at least one of the signals input to the electronic control unit 49 from the various sensors 50-58, information obtained based on these signals, and information based on external (user) input received via the information service unit 59 to an external device via wireless communication. The electronic control unit 49, the various sensors 50-58, the information service unit 59, and the like may also be referred to as input units that receive input. For example, the PUSCH transmitted by the communication module 60 may also include information based on these inputs.

[0784] The communication module 60 receives various information (traffic information, signal information, inter-vehicle information, etc.) transmitted from external devices and displays it on the vehicle's information service unit 59. The information service unit 59 can also be referred to as an output unit that outputs information (for example, outputs information to a device such as a display or speaker based on the PDSCH received by the communication module 60 (or data / information decoded from the PDSCH)).

[0785] Furthermore, the communication module 60 stores various information received from external devices in a memory 62 that can be used by the microprocessor 61. Based on the information stored in the memory 62, the microprocessor 61 can also control the drive unit 41, steering unit 42, accelerator pedal 43, brake pedal 44, shift lever 45, left and right front wheels 46, left and right rear wheels 47, axles 48, various sensors 50-58, and the like included in the vehicle 40.

[0786] Furthermore, the base station in this disclosure can also be rewritten as a user terminal. For example, the various methods / implementations of this disclosure can also be applied to a structure in which communication between a base station and a user terminal is replaced by communication between multiple user terminals (e.g., device-to-device (D2D) or vehicle-to-everything (V2X)). In this case, the user terminal 20 can also have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" can also be rewritten with terms corresponding to inter-terminal communication (e.g., "sidelink"). For example, uplink channels, downlink channels, etc. can also be rewritten as sidelink channels.

[0787] Likewise, the user terminal in the present disclosure may be rewritten as a base station. In this case, the base station 10 may have the functions of the user terminal 20 described above.

[0788] In this disclosure, actions are described as being performed by a base station, and sometimes, depending on circumstances, by its upper node. In a network comprising one or more network nodes including a base station, various operations for communication with a terminal may be performed by the base station, one or more network nodes other than the base station (for example, but not limited to, a Mobility Management Entity (MME) and a Serving-Gateway (S-GW)), or a combination thereof.

[0789] The various methods / implementations described in this disclosure may be used individually or in combination, and may be switched between them during execution. Furthermore, the processing procedures, timings, flow charts, and the like of the various methods / implementations described in this disclosure may be reversed as long as they do not conflict. For example, the methods described in this disclosure use an illustrative order to present elements of various steps, but are not limited to the specific order presented.

[0790] The various modes and embodiments described in the present disclosure may also be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), xth generation mobile communication system (xG (x is, for example, an integer or a decimal)), Future Radio Access (FRA), New Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), systems utilizing other appropriate wireless communication methods, and next-generation systems based on these that are extended, modified, generated, or specified. Furthermore, multiple systems may be combined for application (for example, LTE or LTE-A combined with 5G).

[0791] The phrase “based on” used in this disclosure does not mean “based only on” unless otherwise specified. In other words, the phrase “based on” means both “based only on” and “based at least on.”

[0792] Any reference to an element using the designations "first," "second," etc., as used in this disclosure, does not necessarily define the quantity or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, reference to a first and a second element does not imply that only two elements may be used or that the first element must in some way take precedence over the second element.

[0793] The term "determining" as used in this disclosure may encompass a variety of operations. For example, "determining" may also include judging, calculating, computing, processing, deriving, investigating, looking up (e.g., searching a table, database, or other data structure), ascertaining, and the like as performing a "determination."

[0794] In addition, “judgment (decision)” may also refer to situations where receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, accessing (e.g., accessing data in a memory), etc. are regarded as “judgment (decision)”.

[0795] Furthermore, "judgment (decision)" can also refer to situations where resolving, selecting, choosing, establishing, comparing, and the like are considered "judgment (decision)." In other words, "judgment (decision)" can also refer to situations where certain operations are considered "judgment (decision)." In this disclosure, "judgment (decision)" can be interchanged with the aforementioned operations.

[0796] In this disclosure, "determine / determining" can be interchanged with "assume / assuming," "expect / expecting," "consider / considering," and the like. Furthermore, in this disclosure, "not assuming that..." can be interchanged with "assuming that..."

[0797] In the present disclosure, "expect" and "be expected" can be interchanged. For example, "expect(s) ..." ("..." can also be expressed, for example, using the that clause, the to-infinitive, etc.) can be interchanged with "be expected ...". "Does not expect..." can also be interchanged with "Does not expect ...". Furthermore, "An apparatus A is not expected ..." can be interchanged with "An apparatus B other than apparatus A does not expect ..." (for example, when apparatus A is a UE, apparatus B can also be a base station).

[0798] The “maximum transmit power” described in this disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated maximum transmit power).

[0799] As used in this disclosure, the terms "connected," "coupled," and all variations thereof refer to any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between the two elements being "connected" or "coupled." The coupling or connection between elements can be physical, logical, or a combination thereof. For example, "connected" can also be rephrased as "accessed."

[0800] In the present disclosure, when two elements are connected, it is possible to consider them to be "connected" or "combined" to each other using one or more wires, cables, printed electrical connections, etc., and as several non-limiting and non-inclusive examples, they are "connected" or "combined" to each other using electromagnetic energy having a wavelength in the wireless frequency domain, microwave region, light (both visible and invisible) region, etc.

[0801] In the present disclosure, the term "A is different from B" may also mean "A and B are different from each other." Alternatively, the term may also mean "A and B are each different from C." Terms such as "separate" and "bound" may also be interpreted in the same manner as "different."

[0802] When used in this disclosure, "include," "including," and variations thereof have the same inclusive meaning as the term "comprising." Furthermore, the term "or" used in this disclosure does not mean an exclusive OR.

[0803] In the present disclosure, when an article is added by translation, such as a, an, and the in English, the present disclosure may also include a case where the noun following the article is in a plural form.

[0804] In the present disclosure, “below,” “less than,” “above,” “more,” “equal to,” and the like may be replaced with each other. Furthermore, in the present disclosure, words meaning “good,” “bad,” “big,” “small,” “high,” “low,” “early,” “slow,” “wide,” “narrow,” and the like are not limited to the positive, comparative, and superlative forms, but may be replaced with each other. Furthermore, in the present disclosure, words meaning “good,” “bad,” “big,” “small,” “high,” “low,” “early,” “slow,” “wide,” “narrow,” and the like are not limited to the positive, comparative, and superlative forms, but may be replaced with each other as expressions appended with “the ith” (i is an arbitrary integer) (for example, “the highest” may be replaced with “the ith highest”).

[0805] In the present disclosure, “of,” “for,” “regarding,” “related to,” “associated with,” etc. may also be replaced with each other.

[0806] In this disclosure, expressions such as "when A, B," "if A, (then) B," "B upon A," "B in response to A," "B based on A," "B during / while A," "B before A," "B at (the same time as) / on A," "B after A," "B since A," and "B until A" can be interchanged. Furthermore, A, B, and the like here can be replaced with nouns, gerunds, or ordinary sentences, depending on the context. Furthermore, the time difference between A and B can be approximately zero (immediately after or immediately before). Furthermore, a time offset can be applied to the time when A occurs. For example, "A" can be interchanged with "before / after the time offset when A occurs." This time offset (eg, one or more symbols / time slots) may be predetermined or determined by the UE based on notified information.

[0807] In the present disclosure, timing, moment, time, time instance, arbitrary time unit (eg, time slot, sub-time slot, symbol, sub-frame), period, opportunity (occasion), resource, etc. may also be interchangeably written.
