Description

Terminal, Wireless Communication Method, and Base Station 【0001】 The present disclosure relates to a terminal, a wireless communication method, and a base station in a next-generation mobile communication system. 【0002】 In a Universal Mobile Telecommunications System (UMTS) network, Long Term Evolution (LTE) was standardized for the purpose of further high data rates, low latency, etc. (Non-Patent Document 1). Also, for the purpose of further large capacity and sophistication of LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9), LTE-Advanced (3GPP Rel. 10-14) was standardized. 【0003】 Successor systems to LTE (for example, also referred to as 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 and later, etc.) are also being considered. 【0004】 3GPP TS 36.300 V8.12.0, "Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 (Release 8)", April 2010 【0005】 In a future wireless communication system (for example, NR), it is being considered to apply a semantic base when a terminal (user terminal, User Equipment (UE)) encodes / decodes data (target signal). For example, an adaptive semantic base can be updated based on data to maintain effectiveness. 【0006】However, how to monitor and evaluate the semantic foundation to determine whether it needs updating has not been adequately considered. This could lead to a decrease in communication throughput due to the inability to properly update the semantic foundation. 【0007】 Therefore, one of the objectives of this disclosure is to provide a terminal, a wireless communication method, and a base station that can determine whether it is necessary to update the semantic basis. 【0008】 A terminal according to one aspect of this disclosure is characterized by having a receiving unit that receives setting information for metrics relating to the quality of the semantic infrastructure, and a control unit that monitors the semantic infrastructure based on the metrics. 【0009】 According to one aspect of this disclosure, it is possible to determine whether it is necessary to update the semantic basis. 【0010】 Figure 1 shows an example of compressing a target signal transmitted by a transmitter (UE / NW).

The UE / BS may input channel status information, reference signal measurements, etc., to the AI ​​model and output highly accurate channel status information / measurements / beam selection / position, future channel status information / wireless link quality, etc. 【0014】 In this disclosure, AI may be interpreted as an object (also called a subject, object, data, function, program, etc.) having at least one of the following characteristics: - estimation based on observed or collected information, - selection based on observed or collected information, - prediction based on observed or collected information. 【0015】 In this disclosure, estimation, prediction, and inference may be interpreted interchangeably. Furthermore, in this disclosure, estimate, predict, and infer may be interpreted interchangeably. 【0016】Furthermore, in this disclosure, AI models, models, ML models, predictive analytics, predictive analytics models, tools, autoencoders, encoders, decoders, neural network models, AI algorithms, schemes, etc., may be interpreted interchangeably. Also, AI models may be derived using at least one of the following: regression analysis (e.g., linear regression analysis, multiple regression analysis, logistic regression analysis), support vector machines, random forests, neural networks, deep learning, etc. 【0017】 In this disclosure, the term "autoencoder" may be interpreted interchangeably with any autoencoder, such as a stacked autoencoder or a convolutional autoencoder. The encoder / decoder in this disclosure may employ models such as Residual Network (ResNet), DenseNet, or RefineNet. 【0018】 Furthermore, in this disclosure, terms such as encoder, encoding, encoding / encoded, modification / change / control by an encoder, compression, compression / compressed, generating, and generated / generated may be interpreted interchangeably. 【0019】 Furthermore, in this disclosure, terms such as decoder, decoding, decoding / decoded, modification / change / control by a decoder, decompressing, decompressing / decompressed, reconstructing, and reconstructing / reconstructed may be interpreted interchangeably. 【0020】(Overview of the overall mechanism of the Adaptive semantic basis) Figure 1 shows an example of compressing a target signal transmitted by a transmitter (UE / NW). The following describes an example where the transmitter is a UE. The UE generates / receives a target signal (e.g., image data) and encodes it using an encoder. The UE then applies a semantic basis as post-processing to the encoded signal to generate tokens. The semantic basis may be, for example, a Variational Quantize Variational Autoencoder (VQ-VAE). 【0021】 The UE applies a semantic basis as preprocessing to the post-processed signal, and then applies a proxy decoder to generate proxy received data (reconstructed target signal) corresponding to the token. The UE performs a difference calculation between the proxy received data and the original target signal to generate an increment (information indicating the difference). The UE combines the generated token and increment and transmits it to the network as a payload (UL signal / data). 【0022】 At the network (base station), the transmitted payload is decoded as described below, and the target signal is reconstructed. 【0023】 Figure 2 shows an example of a receiver (NW / UE) reconstructing a received signal. The following describes an example where the receiver is a UE. When the NW (base station) is the transmitter, the UE receives the signal (tokens and increments) and, as a preprocessing step for the decoder, applies a semantic basis and decoder to the tokens and increments to reconstruct the target signal. 【0024】 Furthermore, if UE corresponds to the transmitter in Figure 1, then NW (base station) corresponds to the receiver in Figure 2. If NW (base station) corresponds to the transmitter in Figure 1, then UE corresponds to the receiver in Figure 2. 【0025】Figure 3 shows an example of a payload when using a semantic foundation. A UE can reduce the signal payload by applying an appropriate semantic foundation. However, changes in the communication environment may render the semantic foundation inappropriate, potentially preventing sufficient payload reduction. In such cases, the UE can sufficiently reduce the payload by updating the semantic foundation. 【0026】 For example, when inter-vendor collaboration is considered, the complexity of the frequency of encoder / decoder retraining increases. However, by using an adaptive semantic foundation (an updatable semantic foundation), the frequency of encoder / decoder retraining to adapt to new environments can be reduced. 【0027】 Figure 4 shows an example of updating an AI model without using an adaptive semantic foundation. The network (base station) collects data for training the AI ​​model and updates the AI ​​model. The network transmits the updated AI model to the user interface (UE). 【0028】 Figure 5 shows an example of updating an AI model using an adaptive semantic foundation. The UE / NW updates the adaptive semantic foundation / AI model based on the received data. In this case, the UE / NW does not need to collect data in advance. The UE does not need to receive the model / dataset. 【0029】 (Quantization) A quantization scheme to support VQ-VAE is being considered. The learnable embedding vectors of the Autoencoder (AE) may be considered as an adaptive codebook. An adaptive semantic foundation for physical layer use cases may be an extension of VQ-VAE. 【0030】 <Quantization Information> The following describes information relating to quantization and dequantization (which may be collectively referred to as quantization information or quantization-related information). In this disclosure, quantization and dequantization may be interpreted interchangeably. 【0031】The following may be assumed as quantization information: (1) Information on whether quantizer / dequantizer is supported in training (QAT / QNT support). Or information on whether quantizer / dequantizer is considered during training (QAT / QNT support). This information may include the index(s) of a model trained by QAT using the corresponding quantizer / dequantizer. (2) Information indicating whether quantizer / dequantizer is trainable (updatable during training). This information may include information on the types of trainable quantizer / dequantizer (e.g., ND layer, VQ VAE). (3) Information on how quantizer / dequantizer is constructed. This information may include constructing quantizer / dequantizer based on K-means of bit assignment, etc. (4) Information on whether quantizer / dequantizer is uniform or non-uniform. (5) Information regarding whether the number of bits after quantization is constant for all quantized bits. (6) Information regarding the resolution of uniform or non-uniform quantization. (7) Information regarding the number of units (m) before or after quantization. (8) Information regarding the number of bits (B) after or before quantization. (9) Information regarding whether the quantization / dequantization is a vector or a scalar. (9a-1) If the quantization / dequantization (quantization type) is a vector and the units are evenly divided across the subset, then at least one of the following may be included: (i) the number of units in the subset (m), (ii) the embedding vector (e), (iii) the bit width (b). (9a-2) If the quantization / dequantization (quantization type) is a vector and the units are unevenly divided across the subset, then at least one of the following may be included: (i) the number of units in each subset (m1, m2, ..., m n (ii) Embedding vectors for each subset ({e1}, {e2}, ..., {e n}), (iii) bit width of each subset (b1, b2, ..., b n(9b-1) When quantization / inverse quantization (quantization type) is scalar uniform quantization, the bit width of each unit is (b). (9b-2) When quantization / inverse quantization (quantization type) is scalar non-uniform quantization, the sequence of bit widths of each unit is (b1, b2, ... b M ). 【0032】 <Exchange of pre-processing / post-processing related information (quantization-related information) for model inference> The semantic basis may be quantization information (quantization-related information), or it may be updated based on quantization information (quantization-related information). The following describes the exchange of pre-processing / post-processing related information (quantization-related information) for model inference. 【0033】 The UE may receive the quantization information described above when distributing / transferring the models of both sides. The UE may also receive the quantization information along with the AI ​​model-related information using higher-layer signaling / physical-layer signaling. 【0034】 Figure 6 shows an example of AI model-related information. In addition to model-related information (model ID, model function, model input, model output, scope of application), the related information may also include quantization information (pre-processing / post-processing information). 【0035】 The UE may set / reconfigure the quantization information after the model is delivered / transferred. The UE may further train / update the quantization information after the model is delivered / transferred. This allows the UE to utilize a properly quantized model. 【0036】 <Exchange of pre-processing / post-processing information (quantization-related information) for model inference> This section explains the exchange of pre-processing / post-processing information (quantization-related information) for model updating. 【0037】 The UE may receive the quantization information described above when updating the bidirectional model. The UE may also receive the quantization information along with the AI ​​model-related information using higher-layer signaling / physical-layer signaling. 【0038】 FIG. 7 is a diagram showing another example of AI model-related information. As shown in FIG. 7, in addition to the above-described model-related information (for example, FIG. 6), model parameter 1 (weight), model parameter 2 (quantization information), model structure (structure), etc. may be included. The model-related information may be referred to as model update information. 【0039】 Thereby, the exchange of preprocessing / postprocessing-related information for model update between the UE-NW can be appropriately controlled. 【0040】 (Analysis) As described above, in a future wireless communication system (for example, NR), it is considered to apply a semantic basis when a terminal (user terminal, User Equipment (UE)) encodes / decodes data (target signal). For example, an adaptive semantic basis can be updated based on data to maintain effectiveness. 【0041】 However, how to monitor / evaluate the semantic basis in order to know whether it is necessary to update the semantic basis has not been sufficiently studied. As a result, there is a risk that the communication throughput will decrease because the semantic basis cannot be updated appropriately. 【0042】 Therefore, the inventors have conceived a method that can know whether it is necessary to update the semantic basis. 【0043】 Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings. The wireless communication methods according to the respective embodiments may be applied individually or in combination. 【0044】 (Various readings) In the present disclosure, the words enclosed by “()” in the text may indicate an explanation (for example, a spelling explanation), a paraphrase, a specific example, a supplementary explanation, etc. for the immediately preceding word. Also, in the present disclosure, the words enclosed by “[]” in the text may be interpreted as the meaning of the entire text including this, or the meaning of the entire text may be interpreted without including this (ignoring this). Note that “()” and “[]” may be used for other purposes / meanings. 【0045】 In the present disclosure, "A / B" and "at least one of A and B" may be read interchangeably. Also, in the present disclosure, "A / B / C" may mean "at least one of A, B, and C". 【0046】 In the present disclosure, notify, activate, deactivate, instruct (or indicate), select, configure, update, determine, etc. may be read interchangeably. In the present disclosure, support, control, be able to control, operate, be able to operate, etc. may be read interchangeably. 【0047】 In the present disclosure, Radio Resource Control (RRC), RRC parameters, RRC messages, upper layer parameters, fields, Information Elements (IEs), configurations, etc. may be read interchangeably. In the present disclosure, Medium Access Control control elements (MAC CEs), update commands, activation / deactivation commands, etc. may be read interchangeably. 【0048】 In the present disclosure, upper layer signaling may be any one of, for example, Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, other messages (such as messages from the core network, such as positioning protocol (e.g., NR Positioning Protocol A (NRPPa) / LTE Positioning Protocol (LPP)) messages), or a combination thereof. 【0049】In this disclosure, MAC signaling may include, for example, MAC Control Elements (MAC CEs) and MAC Protocol Data Units (PDUs). Broadcast information may include, for example, Master Information Blocks (MIBs), System Information Blocks (SIBs), Remaining Minimum System Information (RMSIs), and Other System Information (OSIs). 【0050】 In this disclosure, physical layer signaling may include, for example, Downlink Control Information (DCI) and Uplink Control Information (UCI). 【0051】 In this disclosure, terms such as drop, suspend, cancel, puncture, rate match, postpone, and not send may be interpreted interchangeably. 【0052】 In this disclosure, reconstruction and restoration may be interpreted interchangeably. Difference, error, and quantization error may be interpreted interchangeably. Semantic basis and adaptive semantic basis (updatable semantic basis) may be interpreted interchangeably. Monitor and evaluation may be interpreted interchangeably. Performance may be interpreted interchangeably. 【0053】 (Wireless communication method) The semantic basis [set] may be a group of vectors / matrices / parameters, one or more models / sets of models, or part of a model, used to represent the abstracted features of the target signal. Applying the semantic basis may mean, for example, compressing / abstracting / quantizing the target signal using vectors / matrices / models, etc. 【0054】The target signal may be a signal exchanged between nodes (NW / UE) or a signal generated by a node. The target signal may be, for example, at least one of a vector, matrix, message, data, or group of bits. The target signal may be included in PUSCH / PUCCH / PDSCH / PDCCH. The target signal may be a CSI report. 【0055】 Tokens may represent individual features corresponding to a target signal / semantic basis. Tokens may be indices of a vector [or group of vectors] / matrices [or group of vectors] / parameters [or group of vectors] / model / set of models corresponding to the semantic basis, or they may indicate the presence / validity of the semantic basis in the target signal. Tokens may include feature weights, including amplitude, phase, or both. Tokens may be generated by a model (AI model). 【0056】 The increment may represent the difference information between the encoded target signal and the reconstructed target signal. For example, the increment may represent the difference information between the target signal and the target signal reconstructed by the features indicated by a group of tokens (e.g., received tokens). The increment may also be a group of bits representing the difference information. 【0057】 <First Embodiment> The UE may monitor / evaluate the quality of the semantic foundation. Figure 8 shows a method for monitoring / evaluating the quality of the semantic foundation according to the first embodiment. 【0058】 The UE encodes the generated or received target signal, applies a semantic basis to the encoded signal to generate tokens, decodes the tokens to reconstruct the signal (proxy received data), and generates information (increments) indicating the difference between the reconstructed signal and the encoded target signal. The UE then reconstructs (restores) the target signal using the generated increments and the reconstructed signal (proxy received data) obtained by decoding the tokens. 【0059】The UE may receive setting information for metrics related to the quality of the semantic foundation (e.g., vectors / matrices / parameters [groups], or models / parts of models). Based on these metrics, the UE monitors / evaluates the semantic foundation. The metrics are, for example, one of the following options 1-3: 【0060】 [Option 1] The difference (increment) between the decoded and reconstructed token signal and the target signal. For example, in Diff. in Figure 8, the UE compares the token to which the proxy semantic basis has been applied (proxy received data) with the target signal output from the encoder and outputs the difference (increment). The metric may be the magnitude of the increment, or an index / division indicating the magnitude. 【0061】 [Option 2] The number of bits required to indicate (represent) the difference (increment) of the signal relative to the performance target. 【0062】 [Option 3] The error / difference between the reconstructed signal (the signal obtained by compensating / adding the increment to the proxy received data) and the target signal, given that conditions such as payload size (e.g., a predetermined payload size) are set / instructed. The payload size may be set as the payload size for tokens or the payload size for increments, or as the total size (the total size of tokens and increments, with no limit on the number of tokens / increments). 【0063】 The UE may calculate metrics that reflect the quality of the semantic foundation using periodic (P) / semi-persistent (SP) / aperiodic (AP) / event-triggered methods, according to the received settings. 【0064】 [Metric Calculation Procedure] This section describes the procedure by which the UE calculates metrics. The UE may calculate metrics based on the following procedure. 【0065】When the UE calculates the difference between a signal consisting only of transmitted tokens and a target signal, it may reconstruct the target signal based on the transmitted tokens (without increments). The transmitted tokens are referred to as signal #A. The UE may compare signal #A with the target signal and calculate the error / difference as an index (corresponding to option 1). The calculated error / difference may be, for example, Squared Generalized Cosine Similarity (SGCS), Mean Square Error (MSE), Error Vector Magnitude (EVM), etc. 【0066】 The UE may perform performance monitoring for the transmission of one or more specific target signals (or groups of signals) as determined based on the specifications / configurations / instructions. These specific target signals (one or more specific groups of signals) may be, for example, PUCCH / PUSCH or CSI. 【0067】 When the UE calculates the number of bits required to represent the difference (increment) corresponding to the performance objective, it may perform the following steps (corresponding to Option 2): • The UE may receive the performance objective. • The UE may reconstruct the target signal based on the transmitted token (signal #A). • The UE may generate an increment (defined as signal #B) and compensate signal #A with that increment to generate signal #C (signal #C = signal #A + signal #B). • The UE may compare signal #C with the target signal to check whether the performance objective is met. The performance objective may be a target value for quantization error (e.g., SGCS, MSE, EVM). The performance objective may be, for example, no error or a complete reconstruction. The performance objective may be that there is no difference between signal #C and the target signal. • The UE may use the minimum increment length (number of bits) as a metric so that signal #C satisfies the performance objective. 【0068】When the UE calculates the error of a reconstructed signal of a predetermined payload size, it may perform the following steps (corresponding to Option 3): The UE may generate tokens and increments that satisfy the set / specified / instructed payload size [for each token and increment]. The UE may reconstruct the target signal using the generated tokens and increments. The UE may compare the reconstructed target signal with the target signal and derive a metric that reflects the error between the two. The metric may be a quantization error (e.g., SGCS, MSE, EVM). 【0069】 The predetermined payload size may vary depending on the type or size of the target signal. 【0070】 The UE may receive a setting / specification / instruction for the payload size of either a token or an increment, and may determine the payload size of the increment (or token) based on the set / specified / instructed payload size of the token (or increment). 【0071】 The UE may report / transmit the monitoring / evaluation results (metrics below) to the NW. The UE may report / transmit the metrics to the NW if the metrics meet the specified conditions (for example, if the difference between options 1 and 3 exceeds or does not exceed the threshold (performance target), or if the number of bits required to represent the difference between options 2 exceeds or does not exceed the threshold). 【0072】 The UE may decide (or may update) the semantic foundation based on the results of the monitoring / evaluation (metrics below). The UE may update the semantic foundation if the metrics meet certain conditions (for example, if the difference between options 1 and 3 exceeds or does not exceed a threshold (performance target), or if the number of bits required to represent the difference in option 2 exceeds or does not exceed a threshold). 【0073】 According to the first embodiment, the UE can appropriately monitor and evaluate the quality of the semantic foundation, and therefore can appropriately update the semantic foundation. 【0074】 <Supplement> <<Notification of Information to UE>> In the embodiments described above, notification of any information from the Network (NW) (e.g., Base Station (BS)) to the UE (in other words, reception of any information from the BS at the UE) may be performed using physical layer signaling (e.g., DCI), higher layer signaling (e.g., RRC signaling, MAC CE), specific signals / channels (e.g., PDCCH, PDSCH, reference signal), or a combination thereof. 【0075】 If the above notification is made by a MAC CE, the MAC CE may be identified by the inclusion of a new Logical Channel ID (LCID) not defined in existing standards in the MAC subheader. 【0076】 If the above notification is made by DCI, the notification may be made by a specific field of the DCI, a Radio Network Temporary Identifier (RNTI) used to scramble the Cyclic Redundancy Check (CRC) bits assigned to the DCI, or the format of the DCI. 【0077】 Furthermore, notification of any information to the UE in the above-described embodiment may be periodic, semi-persistent (triggered by instructions from the UE or gNB), or aperiodic (triggered by instructions from the UE or gNB). 【0078】 In the embodiments described above, the UE may receive information from the NW as at least one of the following QCL rules: • QCL type A. • QCL type B. • QCL type C. • QCL type D. 【0079】In the embodiments described above, the QCL source RS for each QCL type may be at least one of the following RSs: • SSB;

- A specific UE capability indicating (or related to) the specific process / operation / control / assumption / information is reported or supported; - The application of the specific process / operation / control / assumption / information is determined based on specific conditions. 【0086】 The above-mentioned specific UE capabilities may include at least one of the following: supporting the above-mentioned specific processing / operation / control / assumption / information; supporting a semantic foundation / adaptive semantic foundation; supporting the generation of tokens / increments using a semantic foundation; supporting the reconstruction of a target signal based on tokens / increments generated using a semantic foundation; and supporting the monitoring / evaluation of the quality of a semantic foundation. 【0087】 In this disclosure, "to support" and "whether or not to support" may be interpreted interchangeably. 【0088】Furthermore, the above-mentioned specific UE capability may be a capability that applies across all frequencies (commonly regardless of frequency), a capability per frequency (e.g., one or a combination thereof, such as cell, band, band combination, BWP, component carrier, etc.), a capability per frequency range (e.g., Frequency Range 1 (FR1), FR2, FR3, FR4, FR5, FR2-1, FR2-2), a capability per subcarrier spacing (SCS), or a capability per feature set (FS) or feature set per component-carrier (FSPC). 【0089】 Furthermore, the specific UE capabilities described above may be capabilities that apply across all duplexing schemes (common to all duplexing schemes regardless of the duplexing scheme), or they may be capabilities specific to each duplexing scheme (e.g., Time Division Duplex (TDD), Frequency Division Duplex (FDD)). 【0090】 If the above conditions are not met, UE / BS may follow the behavior specified in existing 3GPP releases. 【0091】(Note) The following inventions are added with respect to one embodiment of the present disclosure.

[Note 4] The terminal described in any of Notes 1 to 3, wherein the control unit applies a semantic basis to the encoded target signal to generate tokens, decodes the tokens to generate information indicating the difference between the reconstructed signal and the encoded target signal, and uses the difference and the reconstructed signal to reconstruct the target signal, and the metric is the difference between the target signal before encoding and the reconstructed target signal. 【0092】 (Wireless Communication System) The configuration of a wireless communication system according to one embodiment of this disclosure will be described below. In this wireless communication system, communication is performed using any of the wireless communication methods according to the above embodiments of this disclosure, or a combination thereof. 【0093】 Figure 9 shows an example of a schematic configuration of a wireless communication system according to one embodiment. The wireless communication system 1 (which may also be simply called system 1) may be a system that realizes communication using Long Term Evolution (LTE), 5th generation mobile communication system New Radio (5G NR), etc., as specified by the Third Generation Partnership Project (3GPP). 【0094】 Furthermore, the wireless communication system 1 may support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), and the like. 【0095】 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. 【0096】 The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity where both MN and SN are NR base stations (gNB) (NR-NR Dual Connectivity (NN-DC))). 【0097】 The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with relatively wide coverage, and base stations 12 (12a-12c) located within the macrocell C1 that form a small cell C2 that is narrower than the macrocell C1. User terminals 20 may be located within at least one cell. The arrangement, number, shape, size, etc., of each cell and user terminal 20 are not limited to the configuration shown in the figure. Hereinafter, when base stations 11 and 12 are not distinguished, they will be collectively referred to as base station 10. 【0098】The wireless communication system 1 may utilize Multi Input Multi Output (MIMO). For example, one cell may be formed by one antenna / base station 10, or by multiple antennas / base stations 10. One [virtual] cell (which may be called a supercell, for example) may be composed of multiple [virtual] cells (which may be called subcells, for example).

The transmitting / receiving unit 220 (transmission processing unit 2211) may perform DFT processing as part of the transmission process to transmit a channel (for example, PUSCH) using a DFT-s-OFDM waveform if transform precoding is enabled for that channel, or it may not perform DFT processing as part of the transmission process if transform precoding is not enabled for that channel. 【0153】 The transmitting / receiving unit 220 (RF unit 222) may perform modulation, filtering, amplification, etc., of the baseband signal to the radio frequency band and transmit the signal in the radio frequency band via the transmitting / receiving antenna 230. 【0154】 On the other hand, the transmitting / receiving unit 220 (RF unit 222) may perform amplification, filtering, demodulation to a baseband signal, etc., on the radio frequency band signal received by the transmitting / receiving antenna 230. 【0155】 The transmitting / receiving unit 220 (receiving processing unit 2212) may apply reception processing such as analog-to-digital conversion, FFT processing, IDFT processing (if necessary), filtering, demapping, demodulation, decoding (may include error correction decoding), MAC layer processing, RLC layer processing, and PDCP layer processing to the acquired baseband signal to acquire user data, etc. 【0156】The transmitting / receiving unit 220 (measuring unit 223) may perform measurements related to the received signal.

The hardware configuration of the base station 10 and the user terminal 20 may include one or more of the devices shown in the figure, or it may be configured without some of the devices. 【0165】 For example, although only one processor 1001 is shown in the diagram, there may be multiple processors. Furthermore, the processing may be performed by one processor, or it may be performed by two or more processors simultaneously, sequentially, or by other means. Note that the processor 1001 may be implemented using one or more chips. 【0166】 Each function in the base station 10 and the user terminal 20 is realized, for example, by loading predetermined software (programs) onto hardware such as the processor 1001 and memory 1002, which allows the processor 1001 to perform calculations and control communication via the communication device 1004, or control at least one of reading and writing data in the memory 1002 and storage 1003. 【0167】 The processor 1001 controls the entire computer, for example, by running an operating system. The processor 1001 may be composed of a central processing unit (CPU) that includes interfaces with peripheral devices, control devices, arithmetic units, registers, etc. For example, at least a part of the control unit 110 (210) and the transmitting / receiving unit 120 (220) described above may be implemented by the processor 1001. 【0168】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 accordingly. The program used is one that causes the computer to execute at least a part of the operations described in the above embodiment. For example, the control unit 110 (210) may be implemented by a control program stored in the memory 1002 and running on the processor 1001, and other functional blocks may be implemented similarly. 【0169】 The memory 1002 is a computer-readable recording medium and may consist of at least one of the following: Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically EPROM (EEPROM), Random Access Memory (RAM), or other suitable storage medium. The memory 1002 may also be called a register, cache, or main memory.

The storage 1003 may also be called an auxiliary storage device. 【0171】The communication device 1004 is hardware (transmitting / receiving device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as a network device, network controller, network card, communication module, etc. The communication device 1004 may be configured to include, for example, a high-frequency switch, duplexer, filter, frequency synthesizer, etc., in order to implement at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmitting / receiving unit 120 (220), transmitting / receiving antenna 130 (230), etc., may be implemented by the communication device 1004. The transmitting / receiving unit 120 (220) may be implemented with physically or logically separated transmitting unit 120a (220a) and receiving unit 120b (220b). 【0172】 The input device 1005 is an input device that accepts input from an external source (e.g., a keyboard, mouse, microphone, switch, button, sensor, etc.). The output device 1006 is an output device that outputs to an external source (e.g., a display, speaker, light-emitting diode (LED) lamp, etc.). The input device 1005 and the output device 1006 may be configured as an integrated unit (e.g., a touch panel). 【0173】 Furthermore, each device, such as the processor 1001 and memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or different buses may be configured for each device. 【0174】Furthermore, the base station 10 and the user terminal 20 may 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), and a field programmable gate array (FPGA), and some or all of each functional block may be implemented using such hardware. For example, the processor 1001 may be implemented using at least one of these hardware components. 【0175】 Furthermore, devices included in the core network 30 (for example, network nodes that provide NF) may also be implemented using the functional block / hardware configuration described above. 【0176】 (Variations) Terms used in this disclosure and terms necessary 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 used interchangeably. Also, a signal may be a message. A reference signal may be abbreviated as RS and may be called a pilot, pilot signal, etc., depending on the applicable standard. Also, a component carrier (CC) may be called a cell, frequency carrier, carrier frequency, etc. 【0177】 A wireless frame may consist of one or more periods (frames) in the time domain. Each of these periods (frames) constituting a wireless frame may be called a subframe. Furthermore, a subframe may consist of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology. 【0178】Here, the neurology may be communication parameters applied to at least one of the transmission and reception of a signal or channel. The neurology may be, for example, at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain. 【0179】 A slot may consist of one or more symbols in the time domain (such as Orthogonal Frequency Division Multiplexing (OFDM) symbols or Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols). Alternatively, a slot may be a time unit based on neurology. 【0180】 A slot may include multiple minislots. Each minislot may consist of one or more symbols in the time domain. Minislots may also be called subslots. Minislots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called a PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using minislots may be called a PDSCH (PUSCH) mapping type B. 【0181】 Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Wireless frames, subframes, slots, minislots, and symbols may each be referred to by different names. Furthermore, the units of time such as frames, subframes, slots, minislots, and symbols in this disclosure may be interpreted as interchangeable. 【0182】For example, one subframe may be called a TTI, multiple consecutive subframes may be called a TTI, and one slot or one mini-slot may be called a TTI. In other words, at least one of a subframe and a TTI may be a subframe in existing LTE (1 ms), a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. Note that the unit representing a TTI may be called a slot, mini-slot, etc., instead of a subframe. 【0183】 Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, the base station schedules each user terminal to allocate wireless resources (such as the frequency bandwidth and transmission power available to each user terminal) in TTI units. However, the definition of TTI is not limited to this. 【0184】 TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the actual time interval (e.g., number of symbols) in which the transport block, code block, code word, etc. are mapped may be shorter than the TTI. 【0185】 Furthermore, if one slot or one mini-slot is referred to as a TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit for scheduling. In addition, the number of slots (number of mini-slots) that constitute this minimum time unit for scheduling may be controlled. 【0186】A TTI with a time length of 1 ms may be called a normal TTI, long TTI, normal subframe, long subframe, slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, mini slot, sub slot, slot, etc. 【0187】 Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more. 【0188】 A Resource Block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers.
