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

[0003] Successor systems to LTE (e.g., 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 or 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] Regarding future wireless communication technologies, the use of artificial intelligence (AI) technologies such as machine learning (ML) for network / device control, management, etc. is being considered. For example, AI technologies that convert signal waveforms for communication (which may also be called AI transformation) are being considered for the purpose of compensating for nonlinear distortion of signal waveforms.

[0006] AI conversion is expected to improve spectral efficiency and system performance, but it is thought that AI conversion increases the computational complexity compared to existing NR signal waveform generation methods.

[0007] However, there has been no progress in studying how to perform settings / controls that can take into account the additional processing time in a terminal (user terminal, User Equipment (UE)) due to such increased computational complexity. Unless these are clearly defined, it may not be possible to perform suitable waveform conversion, which may hinder improvements in communication throughput / communication quality.

[0008] Therefore, one of the objectives of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can appropriately take into account the increase in UE processing time due to AI processing such as AI conversion.

[0009] A terminal according to one aspect of the present disclosure has a receiving unit that receives first information indicating a waveform conversion-related function and second information regarding a time for a downlink channel associated with the first information, and a control unit that determines the time for the downlink channel based on the first information and the second information.

[0010] According to one aspect of the present disclosure, the increase in UE processing time due to AI processing such as AI conversion can be appropriately taken into account.

[0012] (Time-related factors for UE processing in NR) In NR, there are several time-related factors (parameters, constraints) for UE processing. These are outlined below.

[0013] <UE Physical Downlink Shared Channel (PDSCH) Processing Time> In NR, when a UE completes reception of a PDSCH, it takes time to process the PDSCH, so it is not possible to immediately transmit delivery confirmation information (retransmission control information, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.) corresponding to the PDSCH. In NR, the PDSCH processing time, which is the time required to process the received PDSCH, is specified.

[0014] The PDSCH processing time may be interchangeably read as UE PDSCH processing time, [UE] PDSCH processing procedure time, [UE] PDSCH decoding time, and the like.

[0015] In the existing standard, the UE determines whether the first uplink symbol of the PUCCH carrying HARQ-ACK information is the symbol L. １ If it does not start earlier than , it must provide a valid HARQ-ACK message.

[0016] Here, the first uplink symbol is assigned HARQ-ACK timing K １ and K ｏｆｆｓｅｔ (if configured) and the PUCCH resource utilized, and may include the effect / impact of the timing advance.

[0017] K １ K may be a higher layer parameter related to the HARQ-ACK timing (HARQ-ACK timing information, described later). ｏｆｆｓｅｔ may be a scheduling offset based on a higher layer parameter for a cell-specific scheduling offset (cellSpecificKoffset).

[0018] The above-mentioned L １is the time from the end of the last symbol of the PDSCH carrying the identified transport block (TB) to T ｐｒｏｃ，１ T is defined as the next uplink symbol after which the Cyclic Prefix (CP) starts. ｐｒｏｃ，１ corresponds to the PDSCH processing time described above and is calculated by Equation 1. (Equation 1) T ｐｒｏｃ，１ = (N １ +d １，１ +d ２ +d ３ )(2048+144)・κ2 －μ ・T Ｃ +T ｅｘｔ

[0019] Here, N １ may be determined based on μ in Figure 1A (when the UE has / is configured to process PDSCH processing capability 1) and Figure 1B (when the UE has / is configured to process PDSCH processing capability 2). Figure 1A is a diagram showing an example of PDSCH decoding time for PDSCH processing capability 1 specified in the existing NR standard. Figure 1B is a diagram showing an example of PDSCH decoding time for PDSCH processing capability 2 specified in the existing NR standard.

[0020] 1A and 1B are Tables 5.3-1 and 5.3-2 of 3GPP TS 38.214 V18.1.0, respectively.

[0021] μ in Equation 1 is the maximum T ｐｒｏｃ，１ μ ＰＤＣＣＨ , μ ＰＤＳＣＨ , μ ＵＬ For example, μ ＰＤＣＣＨ μ corresponds to the subcarrier spacing (SCS) of the PDCCH that schedules the PDSCH. ＰＤＳＣＨ μ corresponds to the SCS of the scheduled PDSCH. ＵＬ corresponds to the subcarrier spacing of a certain uplink channel. Note that the SCS corresponding to μ is 2 μ ・It may be calculated at 15 [kHz].

[0022] Here, the certain uplink channel is the uplink channel on which HARQ-ACK is assumed to be transmitted, regardless of whether PDSCH reception provides a transport block of a HARQ process with disabled HARQ-ACK information, as indicated by HARQ-feedbackEnabling-disablingperHARQprocess (if set).

[0023] HARQ-feedbackEnabling-disablingperHARQprocess may be a higher layer parameter related to the setting indicating whether or not HARQ feedback is enabled in the HARQ process.

[0024] In Equation 1, κ is T Ｓ and T Ｃ κ is a constant that indicates the ratio between Ｓ / T Ｃ = 64, where T Ｓ denotes the basic time unit for LTE, and T Ｃ indicates the basic time for NR.

[0025] d in Equation 1 １，１ , d ２ may be a value determined based on the PDSCH processing capability, the PDSCH mapping type, the number of symbols of the scheduling PDCCH, the number of symbols of the PDSCH, etc.

[0026] d in Equation 1 ２ may be a value determined based on the priority of PUCCH, PUSCH, etc., or may be 0.

[0027] d in Equation 1 ３The value of d may be determined based on the higher layer parameter (processingType2Enabled) for enabling processing of PDSCH processing capability 2 for UE processing capability 2, the higher layer parameter (enhanced-dmrs-Type_r18) for the enhanced demodulation reference signal (DMRS) type [specified in Rel. 18], or may be 0 if neither of these parameters is set. Also, for UE processing capability 1 (excluding UE processing capability 2), ３ = 0.

[0028] It should be noted that the term "processing capability" may be interchangeably read as "timing capability."

[0029] T in Equation 1 ｅｘｔ T may be calculated according to a predetermined rule in the case of shared spectrum channel access operation in FR1, and may be 0 otherwise. ｅｘｔ may be, for example, the value applied to the first UL transmission scheduled by the scheduling DCI.

[0030] <UE PDSCH reception preparation time> In NR, in the case of cross-carrier scheduling with different SCSs for PDCCH and PDSCH (in other words, the OFDM SCS (μ ＰＤＣＣＨ ) and the PDSCH scheduled to be received by the DCI is received on a carrier in another OFDM SCS (μ ＰＤＳＣＨ ) in the PDSCH reception preparation period (N ｐｄｓｃｈ ) is stipulated.

[0031] μ ＰＤＣＣＨ <μ ＰＤＳＣＨIf the first symbol in a scheduled PDSCH allocation (including DMRS) is at least N symbols from the end of the PDCCH that schedules the PDSCH, ｐｄｓｃｈ The UE is expected to receive the scheduled PDSCH no earlier than the first symbol of the slot for that PDSCH reception, which starts after the PDCCH symbol.

[0032] μ ＰＤＣＣＨ >μ ＰＤＳＣＨ If the first symbol in the scheduled PDSCH allocation (including DMRS) is N symbols from the end of the PDCCH that schedules the PDSCH, ｐｄｓｃｈ The UE is expected to receive the scheduled PDSCH if it starts no sooner after the PDCCH symbol.

[0033] Here, the first symbol in the scheduled PDSCH allocation (including DMRS) is at slot offset K of the scheduling DCI. ０ and Start and Length Indicator Value (SLIV). Note that these symbols (conditions / comparisons) do not take into account the effect of the reception timing difference between the scheduling cell and the scheduled cell.

[0034] FIG. 2 shows the N defined in the existing NR standard. ｐｄｓｃｈ FIG. 2 is a diagram showing an example of Table 5.5-1 of 3GPP TS 38.214 V18.1.0. As shown in this example, ｐｄｓｃｈ is μ ＰＤＣＣＨ may depend on

[0035] <Physical Uplink Shared Channel (PUSCH) Preparation Time> In NR, when a UE receives a DCI format for scheduling a PUSCH, it takes time to prepare the data for the PUSCH, so the PUSCH cannot be transmitted immediately. In NR, a PUSCH preparation time, which is the time required to prepare the PUSCH, is specified.

[0036] Note that the PUSCH preparation time may be interchangeably read as UE PUSCH preparation time, [UE] PUSCH preparation procedure time, [UE] PUSCH processing time, and the like.

[0037] In existing standards, the UE is required to ensure that the first uplink symbol in the PUSCH allocation (including DMRS) for a TB is the symbol L ２ If the TB does not start earlier than , the UE shall transmit the TB. Otherwise, the UE may ignore the scheduling DCI.

[0038] Here, the first uplink symbol is at slot offset K indicated by the time domain resource allocation field of the scheduling DCI. ２ and K. ｏｆｆｓｅｔ (if configured), and the starting symbol S and length L of said PUSCH allocation, and may include the effect / impact of timing advance.

[0039] K ２ K may be a higher layer parameter related to the transmission slot (offset of) of the PUSCH. ｏｆｆｓｅｔ may be a scheduling offset based on a higher layer parameter for a cell-specific scheduling offset (cellSpecificKoffset).

[0040] The above-mentioned L ２ is the time T from the end of reception of the last symbol of the PDCCH carrying the DCI scheduling the PUSCH.ｐｒｏｃ，２ T is defined as the next uplink symbol after which the CP starts. ｐｒｏｃ，２ corresponds to the PUSCH preparation time described above and is calculated by Equation 2. (Equation 2) T ｐｒｏｃ，２ = max ((N ２ +d ２，１ +d ２ )(2048+144)・κ2 －μ ・T Ｃ +T ｅｘｔ +T ｓｗｉｔｃｈ，　 d ２，２ )

[0041] Here, N ２ 3A (when the UE has / is configured to process PUSCH processing capability 1) and FIG. 3B (when the UE has / is configured to process PUSCH processing capability 2). 3A is a diagram showing an example of a PUSCH preparation time for PUSCH processing capability 1 defined in the existing NR standard. 3B is a diagram showing an example of a PUSCH preparation time for PUSCH processing capability 2 defined in the existing NR standard.

[0042] 3A and 3B are Tables 6.4-1 and 6.4-2 of 3GPP TS 38.214 V18.1.0, respectively.

[0043] μ in Equation 2 is the maximum T ｐｒｏｃ，２ μ ＤＬ , μ ＵＬ For example, μ ＰＤＣＣＨ μ corresponds to the downlink SCS in which the PDCCH carrying the DCI scheduling the PUSCH is transmitted. ＵＬ corresponds to the SCS of the uplink channel on which the PUSCH is to be transmitted. Note that the SCS corresponding to μ is μ ・It may be calculated at 15 [kHz].

[0044] κ and T in Equation 2 ｅｘｔ may be the same as Equation 1. Furthermore, max(X, Y) may be a function that finds the maximum value of X and Y.

[0045] d in Equation 2 ２，１may be a value determined based on whether the first symbol of the PUSCH allocation is DMRS only.

[0046] d in Equation 2 ２ may be a value determined based on the priority of PUCCH, PUSCH, etc., or may be 0.

[0047] d in Equation 2 ２，２ may be the BWP switching time if the scheduling DCI triggers a switch of the BWP, or may be 0 otherwise.

[0048] T in Equation 2 ｓｗｉｔｃｈ may be the switching gap time or may be 0.

[0049] <Time Domain Resource Allocation> In NR, in order to set the time domain relationship between the PDCCH and the physical shared channel (PDSCH, PUSCH), time domain resource allocation (TDRA) information may be configured in the UE by higher layer parameters. The TDRA information of the PDSCH may be, for example, the RRC control element "PDSCH-TimeDomainResourceAllocation". The TDRA information of the PUSCH may be, for example, the RRC control element "PUSCH-TimeDomainResourceAllocation".

[0050] One piece of TDRA information may include parameters such as a slot offset between [a PDCCH carrying] a DCI and a physical shared channel scheduled [by the DCI or the PDCCH], a mapping type of the physical shared channel, a start symbol of the physical shared channel, a length of the physical shared channel, etc. Note that the terms TDRA information and TDRA may be interchangeable.

[0051] The slot offset between the DCI (PDCCH) and the PDSCH scheduled by the DCI (PDCCH) is K0, K ０ , k0, k ０In addition, the slot offset between the DCI (PDCCH) and the PUSCH scheduled by the DCI (PDCCH) is K2, K ２ , k2, k ２ It may also be called, for example.

[0052] A time domain resource allocation list containing one or more TDRA information may be configured for the UE. For the PDSCH, a PDSCH time domain resource allocation list (e.g., RRC control element "PDSCH-TimeDomainResourceAllocationList") may be configured. For the PUSCH, a PUSCH time domain resource allocation list (e.g., RRC control element "PUSCH-TimeDomainResourceAllocationList") may be configured.

[0053] In the information signaled by DCI / RRC, the UE is informed which of the configured TDRA information (contained in the time domain resource allocation list) to apply for the information. The information may be a DL assignment (DL scheduling information) for DL ​​and a UL grant (UL scheduling information) for UL. The TDRA information to apply may be indicated, for example, by a TDRA field included in the DCI.

[0054] 4 is a diagram showing some of the RRC information elements related to TDRA information of PDSCH in the existing 3GPP standard. This example is described using Abstract Syntax Notation One (ASN.1) notation. Note that, since this is merely an example, it is acceptable that the description is not complete. This also applies to subsequent similar drawings.

[0055] The RRC control element "PDSCH-TimeDomainResourceAllocation" may include k0, which is an integer value between 0 and 32. The RRC control element "PDSCH-TimeDomainResourceAllocation-r16" that can be used in Rel. 16 NR and later may include k0-r16, which is an integer value between 0 and 32, and k0-v1710, which is an integer value between 33 and 128. Note that k0-v1710 may only be applied to PDSCHs with an SCS of 480 kHz or 960 kHz.

[0056] FIG. 5 is a diagram showing some of the RRC information elements related to TDRA information of the PUSCH in the existing 3GPP standard.

[0057] The RRC control element "PUSCH-TimeDomainResourceAllocation" may include k2, which is an integer value between 0 and 32. The RRC control element "PUSCH-TimeDomainResourceAllocation-r16", which may be used in Rel. 16 NR and later, may include k0-r16, which is an integer value between 0 and 32.

[0058] <HARQ-ACK timing> In NR, the timing from the slot for receiving a PDSCH to transmitting a HARQ-ACK corresponding to the PDSCH (which may also be referred to as HARQ-ACK timing, ACK / NACK (A / N) feedback timing, etc.) may be set in the UE by a higher layer parameter.

[0059] The slot offset between the PDSCH and the HARQ-ACK corresponding to the PDSCH is K1, K2, K3, K4, K5, K6, K7, K8, K9, K10, K11, K12, K13, K14, K15, K16, K17, K18, K19, K20, K21, K22, K23, K24, K25, K26, K27, K28, K2 １ , k1, k １ It may also be called, for example.

[0060] 6 is a diagram illustrating some of the RRC information elements related to HARQ-ACK timing information in the existing 3GPP standard. As shown in the figure, the RRC parameter "dl-DataToUL-ACK" and the RRC control element "DL-DataToUL-ACK-r16" which are HARQ-ACK timing information may be included in the RRC control element "PUCCH-Config" which is PUCCH configuration information.

[0061] The RRC parameter "dl-DataToUL-ACK" indicates a sequence containing 1 to 8 integer values ​​between 0 and 15, inclusive, indicating k1. The RRC control element "DL-DataToUL-ACK-r16", which can be used in Rel. 16 NR and later, indicates a sequence containing 1 to 8 integer values ​​between -1 and 15, inclusive, indicating k1. Note that the value "-1" corresponds to a "not applicable value" when HARQ-ACK timing is not explicitly included in PDSCH scheduling.

[0062] A value in the above sequence may be specified by the PDSCH-to-HARQ feedback timing indication field included in the DCI scheduling the PDSCH. The transmission timing of the HARQ-ACK corresponding to the PDSCH may be determined based on the reception timing of the PDSCH and a specified integer value included in the dl-DataToUL-ACK or DL-DataToUL-ACK-r16.

[0063] (Nonlinear Problems of Power Amplifiers (PAs)) In wireless communication, transmission signals are generally amplified by a power amplifier (PA) in a transmitter. However, it is known that PAs can cause nonlinear distortion, interference, and the like when the input power is large.

[0064] 7 is a diagram showing an example of the input / output characteristics of a PA. In an ideal PA, the output voltage is amplified linearly relative to the input voltage. However, in a real PA, the input voltage has a nearly linear characteristic when it is below a certain value, but when it exceeds that value, the output voltage has a nonlinear characteristic, and the amplification of the output voltage relative to the input voltage becomes saturated.

[0065] FIG. 8 is a diagram showing an example of nonlinear distortion caused by the nonlinear characteristics of a PA. This diagram, also known as a constellation diagram, has the horizontal axis representing in-phase and the vertical axis representing quadrature. This example shows an example of nonlinear distortion experienced by modulation symbols based on 256 Quadrature Amplitude Modulation (QAM). For example, complex numbers corresponding to baseband signals obtained at the receiving end from signals output / transmitted through a PA are plotted. The 256 signal points corresponding to the original modulation symbols are blurred due to nonlinear distortion.

[0066] In addition to PAs, nonlinear distortion can also be caused by oscillators, active elements, passive elements, etc. Only the receiver side can observe the complete nonlinear distortion of the transmitted signal. Because many transmitter and receiver modules are provided by various vendors, there are a huge number of transmitter and receiver combinations, and the nonlinear distortion in DL and UL communications varies greatly.

[0067] As the signal-to-noise ratio (SNR) at the receiver improves, nonlinear distortion interference (e.g., increasing Peak-to-Average Power Ratio (PAPR)) can limit the receiver performance and become a major factor in detected errors.

[0068] (Application of Artificial Intelligence (AI) Technology to Wireless Communications) With regard to future wireless communications technologies, the use of AI technology such as machine learning (ML) for network / device control and management is being considered.

[0069] For example, it is being considered that terminals (user terminals, user equipment (UE)) / base stations (BSs) will utilize AI technology to improve Channel State Information (CSI) feedback (e.g., reduced overhead, improved accuracy, prediction), improve beam management (e.g., improved accuracy, prediction in the time / space domain), and improve position measurement (e.g., improved position estimation / prediction).

[0070] Based on the input information, the AI ​​model may output at least one information such as an estimate, a prediction, a selected action, a classification, etc. The UE / BS may input channel state information, reference signal measurements, etc. to the AI ​​model and output highly accurate channel state information / measurements / beam selection / location, future channel state information / radio link quality, etc.

[0071] In the present disclosure, AI may be interpreted as an object (also called a subject, object, data, function, program, etc.) that has (performs) 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.

[0072] In the present disclosure, estimation, prediction, and inference may be used interchangeably. Also, in the present disclosure, estimate, predict, and infer may be used interchangeably.

[0073] In the present disclosure, an object may be, for example, an apparatus, device, etc., such as a UE or a BS. Also, in the present disclosure, an object may correspond to a program / model / entity that operates in the apparatus.

[0074] For future wireless communication technologies (e.g., 3GPP Rel. 19, 20, 21), the use of AI technology to compensate for the above-mentioned nonlinear distortion is being considered.

[0075] Figure 9 is a diagram showing an example of compensation for nonlinear distortion caused by the nonlinear characteristics of a PA. This example shows an example in which the nonlinear distortion in Figure 8 is compensated for using a certain AI technology. Points close to the original 256 signal points are plotted, demonstrating that the impact of nonlinear distortion can be reduced by AI technology.

[0076] The compensation of the nonlinear distortion may be performed at the transmitter side / receiver side. For example, in one scenario of adopting AI, a one-sided model for either the transmitter or the receiver may be adopted, and in another scenario, a two-sided model for both the transmitter and the receiver may be adopted.

[0077] AI techniques for transforming signal waveforms for communications (which may also be referred to as AI transformation, AI-based transformation, AI waveform transformation, waveform conversion, etc.) are being considered to compensate for nonlinear distortion, reduce additional CP, etc. AI transformation may include, for example, at least one of the following using AI techniques: signal constellation compensation, modulation scheme selection, modulation, sequence generation, selective mapping of complex-valued [modulation] symbols, tone reservation (TR), resource [element] mapping, and transformation (e.g., shift / scale) of complex-valued / time-continuous signals.

[0078] For example, signal constellation compensation may correspond to a technique for mitigating nonlinear effects and reducing Peak-to-Average Power Ratio (PAPR) problems by shifting / scaling / rotating a signal constellation at the transmitter / receiver side.

[0079] AI conversion is expected to improve spectral efficiency and system performance, but it is thought that AI conversion increases the computational complexity compared to existing NR signal waveform generation methods.

[0080] The inventors have found that, considering the processing capabilities of the UE, the increased computational complexity due to AI conversion results in additional processing time in the UE. Therefore, it is preferable to adjust the time-related elements of the UE processing described above with respect to AI conversion, but the relevant settings / controls have not yet been studied. Unless these are clearly defined, it may be impossible to perform suitable waveform conversion, which may hinder improvements in communication throughput / communication quality.

[0081] Therefore, the present inventors have conceived a suitable setting / control method for waveform conversion. According to one aspect of the present disclosure, performance can be improved (for example, nonlinearity problems in PA can be reduced) by using a waveform conversion function that takes into account the interaction between a UE and a network (NW).

[0082] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings. Wireless communication methods according to the embodiments may be applied independently or in combination.

[0091] In this disclosure, a "model identifier (ID)" may refer to an ID associated with a functionality / additional condition (or a model corresponding to that ID). Note that a model ID may be interchangeably read as an AI ID, a dataset ID, a pairing ID, etc.

[0092] In the present disclosure, function / functionality may be read as any of feature, function, and functionality.

[0093] In the present disclosure, the terms model, function, functionality, model ID, function ID, functionality ID, etc. may be read interchangeably.

[0094] In the following embodiments, AI conversion may be interchangeably read as any AI processing.

[0095] (Wireless Communication Method) First Embodiment The first embodiment relates to an AI indicator (which may also be called AI specific information) and AI granularity.

[0096] The AI ​​indicator / AI granularity may be set / confirmed for the UE or may be reported by the UE to the NW. In the present disclosure, the AI ​​indicator / AI granularity may be set / confirmed / reported for the above-mentioned AI transformations (e.g., one or more of AI-based waveform, AI-based resource element mapping, AI-based sequence handling, AI-based tone handling, AI-based modulation / demodulation, etc.), or may be set / confirmed / reported in association with an AI function / model.

[0097] The AI ​​indicator may indicate the selected AI transformation function. The AI ​​indicator may be expressed in (or associated with) any of the following units or combinations thereof: Parts separated by AI granularity; Some combination of parts separated by AI granularity.

[0098] The AI ​​granularity may be at least one of the following (may be set in at least one of the following units): - per model or fine granularity, - per function or [first] medium granularity, - per model information or [second] medium granularity, - per complexity or coarse granularity.

[0099] The model information may be at least one of information about the AI ​​model, such as the number of layers, the size of input / output, model structure, etc. The complexity may be, for example, UE capability.

[0100] As an example, if the AI ​​indicator is determined for each portion divided by the AI ​​granularity, the AI ​​indicator may indicate a model if the AI ​​granularity is fine, or may indicate a function if the AI ​​granularity is [first] medium.

[0101] One or more AI indicators / AI granularities may be specified to the UE by DCI / MAC CE / RRC in association with one or more PDCCH / PUCCH / PDSCH / PUSCH.

[0102] For example, from multiple AI indicators configured in RRC, some AI indicators may be activated by the MAC CE, and one or more AI indicators from the activated AI indicators may be assigned to the UE by a specific field (e.g., AI indicator field) of the DCI. For example, one or more AI indicators may assign only an AI-based waveform function, a combination of an AI-based waveform function and an AI-based modulation function, or the entire AI-based conversion function.

[0103] The available AI indicators may be different for one or more of the PDCCH, PUCCH, PDSCH, and PUSCH. For example, the multiple AI indicators configured in the RRC described above may be different for one or more of the PDCCH, PUCCH, PDSCH, and PUSCH.

[0104] Note that a specific AI indicator [specifying a model / function] may be set as a default setting. For example, if a certain AI process is to be performed but the corresponding AI indicator is not specified, the UE may use the specific AI indicator as the default setting for the AI ​​process.

[0105] According to the first embodiment described above, for example, it is possible to appropriately specify the AI ​​conversion function for the UE, and appropriately report the AI ​​conversion function supported by the UE to the NW.

[0106] Second Embodiment The second embodiment relates to the PDSCH processing time.

[0107] In association with the AI ​​indicator, the PDSCH processing time may be configured / confirmed for the UE or reported by the UE to the NW. In other words, the UE may determine the PDSCH processing time based on the AI ​​indicator.

[0108] The AI ​​indicator in the description of the second embodiment may correspond to an AI indicator associated with at least one of the PDCCH (which schedules the PDSCH), the PDSCH, and the PUCCH which transmits the HARQ-ACK corresponding to the PDSCH.

[0109] The second embodiment is broadly divided into the following three embodiments: - Embodiment 2.1: Extending the existing table of PDSCH processing time settings; - Embodiment 2.2: Introducing additional PDSCH processing time settings; - Embodiment 2.3: Introducing a new table of PDSCH processing time settings.

[0110] <<Embodiment 2.1>> In embodiment 2.1, the existing table regarding the PDSCH processing time may be extended. In other words, in embodiment 2.1, the PDSCH decoding time N １ may be associated with the AI ​​indicator using a table that extends an existing table.

[0111] FIG. 10 is a diagram showing an example of an extension table of PDSCH decoding times for PDSCH processing capability 1 in embodiment 2.1.

[0112] In this example, the "Normal" column indicates the normal PDSCH decoding time N1 regardless of the AI ​​indicator. The "AI Indicator i" column (i is an integer) indicates the PDSCH decoding time N for the PDSCH associated with the AI ​​indicator i. １ Shows.

[0113] Note that the column names such as "Normal" and "AI Indicator i" and the values ​​in the table are merely examples, and may be replaced with any column names and values.

[0114] Any value in the table may be predefined or may be determined based on at least one of parameters set / indicated to the UE by higher layer signaling / physical layer signaling, UE capabilities, associated functionality / model, etc.

[0115] The values ​​in the table may depend on the SCS (the values ​​may be different for each SCS), and as shown, the example table may be extended for μ>6 (e.g. μ=7, 8, ...).

[0116] It should be noted that the table format is not necessarily used. For example, the PDSCH decoding time N for the PDSCH related to the AI ​​indicator i for μ is １、μ is the function f(N １、０ , μ), the UE is configured １、０ and a function f whose parameters are set or defined, １、μ You may ask for:

[0117] These may be similar to other table examples below, so they will not be described again.

[0118] Similar to the above-described extended table of PDSCH decoding times for PDSCH processing capability 1, an extended table of PDSCH decoding times for PDSCH processing capability 2 may be defined based on the existing table of PDSCH decoding times for PDSCH processing capability 2. When a UE has / is configured to process PDSCH processing capability 2, the PDSCH decoding time N is set based on the extended table of PDSCH decoding times for PDSCH processing capability 2. １ may be determined.

[0119] <<Embodiment 2.2>> In embodiment 2.2, the existing calculation formula for the PDSCH processing time may be extended or a variable may be added. In other words, in embodiment 2.2, the PDSCH decoding time N １ Variables other than may be associated with the AI ​​indicator.

[0120] For example, instead of Equation 1 above, T ｐｒｏｃ，１may be calculated by Equation 3. (Equation 3) T ｐｒｏｃ，１ = (N １ +N ａｉ +d １，１ +d ２ +d ３ )(2048+144)・κ2 －μ ・T Ｃ +T ｅｘｔ

[0121] Here, N ａｉ may be determined by the PDSCH decode [addition] time relative to the AI ​​indicator. For example, N ａｉ is the PDSCH decoding time N of the selected AI indicator [i] ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ may be equal to (N ａｉ = N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ ).

[0122] Also, N ａｉ is the PDSCH decoding time of one or more selected AI indicators (e.g., N for AI indicator i). ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ ) (e.g., if AI indicators 1 and 3 are selected, N ａｉ = max (N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ , N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ )).

[0123] Also, N ａｉ may be calculated based on the sum of the PDSCH decoding times of one or more selected AI indicators (e.g., if AI indicators 1 and 3 are selected, N ａｉ = N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ +N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ ).

[0124] In addition, N ａｉ is a different name (e.g., d ４ , d ａｉ ) or T ｅｘｔ and similar time unit parameters (e.g., T ａｉ For example, instead of the above equation 1, T ｐｒｏｃ，１ may be calculated by Equation 4. (Equation 4) T ｐｒｏｃ，１ = (N １ +d １，１ +d２ +d ３ )(2048+144)・κ2 －μ ・T Ｃ +T ｅｘｔ +T ａｉ

[0125] Also, T ｐｒｏｃ，１ remains as in Equation 1, and the above-mentioned L １ T in the definition of ｐｒｏｃ，１ T ｐｒｏｃ，１ +T ａｉ (which can be said to be equivalent to Equation 4).

[0126] 11 is a diagram showing an example of a table of PDSCH decoding times for PDSCH processing capability 1 in embodiment 2.2. In this example, the PDSCH decoding time N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ The PDSCH decoding time N for another AI indicator i is ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ A table for may be defined separately.

[0127] The PDSCH decoding time N of the AI ​​indicator [i] for the PDSCH processing capability 1 ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ Similarly to the table for PDSCH processing capability 2, the PDSCH decoding time N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ If a UE has PDSCH processing capability 2 and is configured to process / has PDSCH decoding time N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ Based on the table [and equation 3 / 4] for T ｐｒｏｃ，１ may be determined.

[0128] <<Embodiment 2.3>> In embodiment 2.3, a new table for PDSCH processing times associated with AI granularity / specified by AI indicators may be defined. For example, in embodiment 2.3, the PDSCH decoding time N １ may be associated with the AI ​​indicator using a new table rather than an existing table.

[0129] A new table may be defined for each AI granularity (e.g., model, function, UE capability), for example, a table of PDSCH decoding times for UE capabilities related to AI processing (e.g., may be referred to as UE capability 3, PDSCH processing capability 3, etc.) may be defined.

[0130] 12 is a diagram showing an example of a table of PDSCH decoding times for PDSCH processing capability 3 in embodiment 2.3. １ may be used for Equation 1 when the UE reports to the network that it supports PDSCH processing capability 3 or is configured by the network to process PDSCH processing capability 3. The table in Figure 12 may be specified, for example, as Table 5.3-3 (PDSCH processing time for PDSCH processing capability 3) in 3GPP TS 38.214 V18.1.0.

[0131] According to the second embodiment described above, it is possible to appropriately set the PDSCH processing time that can accommodate an increase in UE processing time due to AI conversion.

[0132] <Third Embodiment> The third embodiment relates to a PDSCH reception preparation time.

[0133] In association with the AI ​​indicator, the PDSCH reception preparation time may be configured / confirmed for the UE or reported by the UE to the NW. In other words, the UE may determine the PDSCH reception preparation time based on the AI ​​indicator.

[0134] The AI ​​indicator in the description of the third embodiment may correspond to an AI indicator associated with at least one of a PDCCH (which schedules a PDSCH) and a PDSCH scheduled by the PDCCH.

[0135] The third embodiment is roughly divided into the following two: Embodiment 3.1: Extending the existing table for PDSCH reception preparation time setting; and Embodiment 3.2: Introducing an additional PDSCH reception preparation time setting.

[0136] <<Embodiment 3.1>> In embodiment 3.1, an existing table relating to the PDSCH reception preparation time may be extended. In other words, in embodiment 3.1, the PDSCH reception preparation time N ｐｄｓｃｈ may be associated with the AI ​​indicator using a table that extends an existing table.

[0137] FIG. 13 shows the N ｐｄｓｃｈ FIG. 10 is a diagram illustrating an example of an extension table.

[0138] In this example, the "Normal" column indicates the normal PDSCH reception preparation time N ｐｄｓｃｈ The column "AI Indicator i" (i is an integer) indicates the PDSCH reception preparation time N for the PDCCH / PDSCH related to the AI ​​indicator i. ｐｄｓｃｈ Shows.

[0139] <<Embodiment 3.2>> In embodiment 3.2, the PDSCH reception preparation time N ｐｄｓｃｈ Variables other than may be associated with the AI ​​indicator.

[0140] For example, N shown in FIG. ｐｄｓｃｈ and N ａｉ The sum of (N ｐｄｓｃｈ +N ａｉ ) may be used as the PDSCH reception preparation time. ａｉ may be determined by the PDSCH reception preparation [additional] time for the AI ​​indicator. For example, N ａｉ is the PDSCH reception preparation time N of the selected AI indicator [i] ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ may be equal to (N ａｉ = N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ ).

[0141] Also, N ａｉ is the PDSCH reception preparation time of one or more selected AI indicators (e.g., N for AI indicator i). ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ ) (for example, if AI indicators 1 and 3 are selected, N ａｉ = max (Nａｉ＿ｉｎｄｉｃａｔｏｒ＿１ , N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ )).

[0142] Also, N ａｉ may be calculated based on the sum of the PDSCH reception preparation times of one or more selected AI indicators (e.g., if AI indicators 1 and 3 are selected, N ａｉ = N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ +N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ ).

[0143] In addition, N ａｉ is a different name (e.g., d ａｉ ) may also be called.

[0144] N ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ may be represented by a separate table for each AI indicator i, as shown in FIG.

[0145] According to the third embodiment described above, it is possible to appropriately set the PDSCH reception preparation time that can accommodate the increase in UE processing time due to AI conversion.

[0146] <Fourth Embodiment> The fourth embodiment relates to a PUSCH preparation time.

[0147] In association with the AI ​​indicator, the PUSCH preparation time may be configured / confirmed for the UE or reported by the UE to the NW. In other words, the UE may determine the PUSCH preparation time based on the AI ​​indicator.

[0148] The AI ​​indicator in the description of the fourth embodiment may correspond to an AI indicator associated with at least one of the PDCCH and the PUSCH (which schedules the PUSCH).

[0149] The fourth embodiment can be broadly divided into the following three embodiments: - Embodiment 4.1: Extending the existing table for PUSCH preparation time settings; - Embodiment 4.2: Introducing additional PUSCH preparation time settings; - Embodiment 4.3: Introducing a new table for PUSCH preparation time settings.

[0150] <<Embodiment 4.1>> In embodiment 4.1, an existing table regarding the PUSCH preparation time may be extended. In other words, in embodiment 4.1, the PUSCH preparation time N ２ may be associated with the AI ​​indicator using a table that extends an existing table.

[0151] FIG. 14 is a diagram showing an example of an extended table of PUSCH preparation times for PUSCH timing capability 1 in embodiment 4.1.

[0152] In this example, the "Normal" column indicates the normal PUSCH preparation time N ２ The column "AI Indicator i" (i is an integer) indicates the PUSCH preparation time N for the PUSCH related to AI indicator i. ２ Shows.

[0153] Similar to the above-mentioned extended table of PUSCH preparation times for PUSCH timing capability 1, an extended table of PUSCH preparation times for PUSCH timing capability 2 may be defined based on the existing table of PUSCH preparation times for PUSCH timing capability 2. When a UE has / is configured to process PUSCH timing capability 2, the PUSCH preparation time N is set based on the extended table of PUSCH preparation times for PUSCH timing capability 2. ２ may be determined.

[0154] <<Embodiment 4.2>> In embodiment 4.2, the existing calculation formula for the PUSCH preparation time may be extended or a variable may be added. In other words, in embodiment 4.2, the PUSCH preparation time N ２ Variables other than may be associated with the AI ​​indicator.

[0155] For example, instead of Equation 2 above, T ｐｒｏｃ，２ may be calculated by Equation 5. (Equation 5) T ｐｒｏｃ，２ = max ((N ２ +N ａｉ +d ２，１ +d ２ )(2048+144)・κ2 －μ・T Ｃ +T ｅｘｔ +T ｓｗｉｔｃｈ，　 d ２，２ )

[0156] Here, N ａｉ may be determined by the PUSCH preparation [addition] time for the AI ​​indicator. For example, N ａｉ is the PUSCH preparation time N of the selected AI indicator [i] ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ may be equal to (N ａｉ = N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ ).

[0157] Also, N ａｉ is the PUSCH preparation time of one or more selected AI indicators (e.g., N for AI indicator i). ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ ) (for example, if AI indicators 1 and 3 are selected, N ａｉ = max (N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ , N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ )).

[0158] Also, N ａｉ may be calculated based on the sum of the PUSCH preparation times of one or more selected AI indicators (e.g., if AI indicators 1 and 3 are selected, N ａｉ = N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ +N ａｉ＿ｉｎｄｉｃａｔｏｒ＿３ ).

[0159] In addition, N ａｉ is a different name (e.g., d ４ , d ａｉ ) may also be called N ａｉ Is T ｅｘｔ and similar time unit parameters (e.g., T ａｉ For example, instead of Equation 2 above, T ｐｒｏｃ，２ may be calculated by Equation 6. (Equation 6) T ｐｒｏｃ，２ = max ((N ２ +N ａｉ +d ２，１ +d ２ )(2048+144)・κ2 －μ ・T Ｃ +T ｅｘｔ +Tｓｗｉｔｃｈ +T ａｉ，　 d ２，２ )

[0160] Also, T ｐｒｏｃ，２ remains as in Equation 2, and the above-mentioned L ２ T in the definition of ｐｒｏｃ，２ T ｐｒｏｃ，２ +T ａｉ (which can be said to be equivalent to Equation 6).

[0161] 15 is a diagram showing an example of a table of PUSCH preparation times for PUSCH timing capability 1 in embodiment 4.2. In this example, the PUSCH preparation time N ａｉ＿ｉｎｄｉｃａｔｏｒ＿１ The PUSCH preparation time N ａｉ＿ｉｎｄｉｃａｔｏｒ＿ｉ A table for may be defined separately.

[0162] The PUSCH preparation time N of the AI ​​indicator [i] for the PUSCH timing capability 1 ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ Similarly to the table for PUSCH timing capability 2, the PUSCH preparation time N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ If a UE has PUSCH timing capability 2 and is configured to process PUSCH timing capability 2, a table for PUSCH preparation time N ａｉ_ｉｎｄｉｃａｔｏｒ［＿ｉ］ Based on the table [and equations 5 / 6] for T ｐｒｏｃ，２ may be determined.

[0163] <<Embodiment 4.3>> In embodiment 4.3, a new table for PUSCH preparation times associated with AI granularity / specified by AI indicators may be defined. For example, in embodiment 4.3, the PUSCH preparation time N ２ may be associated with the AI ​​indicator using a new table rather than an existing table.

[0164] A new table may be defined for each AI granularity (e.g., model, function, UE capability). For example, a table of PUSCH preparation times for UE capabilities related to AI processing (e.g., may be referred to as UE capability 3, PUSCH timing capability 3, etc.) may be defined.

[0165] 16 is a diagram showing an example of a table of PUSCH preparation times for PUSCH timing capability 3 in embodiment 4.3. ２ may be used for Equation 2 when the UE reports to the network that it supports PUSCH timing capability 3 or is configured by the network to process PUSCH timing capability 3. The table in Figure 16 may be specified, for example, as Table 6.4-3 (PUSCH preparation time for PUSCH timing capability 3) in 3GPP TS 38.214 V18.1.0.

[0166] According to the fifth embodiment described above, it is possible to appropriately set the PUSCH preparation time that can accommodate the increase in UE processing time due to AI conversion.

[0167] Fifth Embodiment The fifth embodiment relates to k0 of TDRA information of PDSCH.

[0168] In the fifth embodiment, control may be performed to accommodate a wider range of k0 than the existing range of k0, taking into account, for example, the PDCCH demodulation / decoding time added by AI conversion.

[0169] In association with the AI ​​indicator, k may be configured / confirmed for the UE. In other words, the UE may determine k based on the AI ​​indicator. The AI ​​indicator in the description of the fifth embodiment may correspond to the AI ​​indicator associated with the PDCCH / PDSCH (which schedules the PDSCH).

[0170] The fifth embodiment can be broadly divided into the following three: - Embodiment 5.1: Extending the existing range (domain) of k0; - Embodiment 5.2: Introducing a new parameter for k0; - Embodiment 5.3: Introducing a new parameter that complements (constitutes) k0.

[0171] In the fifth embodiment, k0 may be interchangeably read as other parameters related to k0, such as k0-r16 and k0-v1710 (the fifth embodiment may be applied to these).

[0172] Furthermore, the RRC information elements / parameters / fields described hereinafter regarding the fifth embodiment may be given notations such as "-rXX (or -VXXXX)" corresponding to 3GPP release numbers (e.g., 3GPP Rel. 19) or existing notations may be overwritten. However, for simplicity, the following description will be given without any notations.

[0173] <<Embodiment 5.1>> In embodiment 5.1, the existing range (domain) of k0 may be extended. When instructing a UE of an AI indicator related to a PDCCH, the base station may control to use k0 indicated by the PDCCH in a range extended from the existing range.

[0174] k0 may be set in the UE according to existing rules, or may be set according to (or associated with) the AI ​​indicator for AI conversion.

[0175] 17 is a diagram showing some of the RRC information elements related to TDRA information of the PDSCH in embodiment 5.1. In this example, k0 is an integer value between 0 and 64, and can take a value in a wider range than the existing k0 (in FIG. 4).

[0176] Note that this number "64" is merely an example and may be another number [larger than the upper limit of the existing k0 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PDSCH.

[0177] <<Embodiment 5.2>> In embodiment 5.2, in addition to k0, k0 (for each AI indicator) for the case where an AI conversion is applied (e.g., k0 for AI indicator i may be referred to as k0-AI-Indicator-i) may be set. In this embodiment, k0 not related to an AI indicator (e.g., when an AI indicator is not set) may be referred to as an existing [defined in the standard] k0, a normal k0, a base k0, a default k0, etc.

[0178] Which setting of the configured base k0 and each k0-AI-Indicator-i is valid (which setting is actually used to determine the timing of the PDSCH) may depend on the configured AI indicator. For example, when AI indicator 1 is configured, k0-AI-Indicator-1 may be selected.

[0179] 18 is a diagram showing some of the RRC information elements related to the TDRA information of the PDSCH in embodiment 5.2. In this example, in addition to the base k0, k0-AI-Indicator-1 and k0-AI-Indicator-2, which are integer values ​​between 0 and 64 and can take on a wider range of values ​​than the existing k0 (in FIG. 4), can be set.

[0180] Note that this number "64" is merely an example and may be another number [larger than the upper limit of the existing k0 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PDSCH.

[0181] <<Embodiment 5.3>> In embodiment 5.3, k0 actually used to determine the timing of PDSCH is calculated based on k0 not associated with the AI ​​indicator (e.g., when the AI ​​indicator is not set) and k0 (for each AI indicator) for the case where an AI conversion is applied (e.g., k0 for AI indicator i may be referred to as k0-AI-Indicator-i). In this embodiment, k0 not associated with the AI ​​indicator may be referred to as an existing [standard-defined] k0, a normal k0, a base k0, a default k0, or the like.

[0182] The k0 actually used to determine the timing of the PDSCH may be calculated by Equation 7. (Equation 7) k0 = base k0 + Σ(e ｉ *k0-AI-Indicator-i)

[0183] Here, e ｉ is a value that depends on whether AI indicator i is set or not. For example, if AI indicator i is set, e ｉ = 1, otherwise e ｉ = 0. In other words, Equation 7 means that the value obtained by adding all the k0 values ​​for the set AI indicator i to the base k0 is used as k0.

[0184] 19 is a diagram showing some of the RRC information elements related to the TDRA information of the PDSCH in embodiment 5.3. In this example, in addition to the base k0, k0-AI-Indicator-1 and k0-AI-Indicator-2, which are integer values ​​between 0 and 32, can be set. k0-AI-Indicator-1 and k0-AI-Indicator-2 do not have to be able to take values ​​in a wider range than the existing k0 (in FIG. 4).

[0185] Note that this number "32" is merely an example and may be another number [less than (or greater than) the upper limit of the existing k0 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PDSCH.

[0186] <<Modifications>> In Embodiments 5.1 to 5.3, information on k0 is included in the RRC control element "PDSCH-TimeDomainResourceAllocation." However, the information may be set by an RRC control element other than the RRC control element "PDSCH-TimeDomainResourceAllocation," or may be specified in advance in a standard. Furthermore, the RRC control element "PDSCH-TimeDomainResourceAllocationList" including information on k0 may be set in association with an AI indicator (e.g., for each AI indicator).

[0187] According to the fifth embodiment described above, k0 can be appropriately set to accommodate an increase in UE processing time due to AI conversion.

[0188] Sixth Embodiment The sixth embodiment relates to k1 indicating HARQ-ACK timing for PDSCH.

[0189] In the sixth embodiment, control may be performed to accommodate a wider range of k1 than the existing range of k1, taking into account, for example, the PDSCH processing time [ / processing time for PUCCH (UCI)] added by AI conversion. Note that in the present disclosure, k1 may be interchangeably read as the value of each entry of the HARQ-ACK timing information (for example, the value of an individual entry in the sequence of "dl-DataToUL-ACK" or "DL-DataToUL-ACK-r16").

[0190] In association with the AI ​​indicator, k1 may be configured / confirmed for the UE. In other words, the UE may determine k1 based on the AI ​​indicator. The AI ​​indicator in the description of the sixth embodiment may correspond to the AI ​​indicator associated with the PDSCH / PUCCH.

[0191] The sixth embodiment can be broadly divided into the following three: - Embodiment 6.1: Extending the existing range (domain) of k1; - Embodiment 6.2: Introducing a new parameter for k1; - Embodiment 6.3: Introducing a new parameter that complements (constitutes) k1.

[0192] In addition, in the sixth embodiment, "dl-DataToUL-ACK" may be interchangeably read as other k1-related parameters such as "DL-DataToUL-ACK-r16", "DL-DataToUL-ACK-r17", "DL-DataToUL-ACK-v1700", "DL-DataToUL-ACK-DCI-1-2-r16", and "DL-DataToUL-ACK-DCI-1-2-r17" (the sixth embodiment may be applied to these).

[0193] Furthermore, the RRC information elements / parameters / fields described hereinafter in relation to the sixth embodiment may be given a notation such as "-rXX (or -VXXXX)" corresponding to a 3GPP release number (e.g., 3GPP Rel. 19) or may have an existing notation overwritten. However, for simplicity, the description will be given without any notation.

[0194] <<Embodiment 6.1>> In embodiment 6.1, the existing range (domain) of k1 may be extended. When instructing a UE of an AI indicator related to a PDSCH / PUCCH, the base station may control k1 for the PDSCH / PUCCH to use a range of k1 that is extended from the existing range.

[0195] k1 may be set in the UE according to existing rules, or may be set according to (or associated with) an AI indicator for AI conversion.

[0196] 20 is a diagram illustrating a part of an RRC information element related to HARQ-ACK timing information in embodiment 6.1. In this example, k1 is an integer value between 0 and 31, and can take a value in a wider range than the existing k1 (in FIG. 6).

[0197] Note that the number "31" is merely an example and may be another number [larger than the upper limit of the existing k1 range (e.g., 15)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH.

[0198] <<Embodiment 6.2>> In embodiment 6.2, in addition to k1, k1 (for each AI indicator) for the case where an AI conversion is applied (e.g., k1 for AI indicator i may be referred to as k1-AI-Indicator-i) may be set. In this embodiment, k1 not related to an AI indicator (e.g., when an AI indicator is not set) may be referred to as an existing [defined in the standard] k1, a normal k1, a base k1, a default k1, etc.

[0199] Which setting of the configured base k1 and each k1-AI-Indicator-i is valid (which setting is actually used to determine the HARQ-ACK timing) may depend on the configured AI indicator. For example, when AI indicator 1 is configured, k1-AI-Indicator-1 may be selected.

[0200] 21 is a diagram illustrating a part of RRC information elements related to HARQ-ACK timing information in embodiment 6.2. In this example, in addition to the base k1, k1-AI-Indicator-1 and k1-AI-Indicator-2, which are integer values ​​between 0 and 31 and can take a wider range of values ​​than the existing k1 (in FIG. 6), can be set.

[0201] Note that the number "31" is merely an example and may be another number [larger than the upper limit of the existing k1 range (e.g., 15)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH.

[0202] <<Embodiment 6.3>> In embodiment 6.3, k1 actually used to determine the HARQ-ACK timing is calculated based on k1 not related to the AI ​​indicator (e.g., when the AI ​​indicator is not set) and k1 (for each AI indicator) for the case where an AI conversion is applied (e.g., k1 for AI indicator i may be referred to as k1-AI-Indicator-i). In this embodiment, k1 not related to the AI ​​indicator may be referred to as an existing [standard-defined] k1, a normal k1, a base k1, a default k1, etc.

[0203] The k1 actually used to determine the timing of the PDSCH may be calculated by Equation 8. (Equation 8) k1 = base k1 + Σ(e ｉ *k1-AI-Indicator-i)

[0204] Here, e ｉ is a value that depends on whether AI indicator i is set or not. For example, if AI indicator i is set, e ｉ = 1, otherwise e ｉ = 0. In other words, Equation 8 means that the value obtained by adding all the k1s for the set AI indicator i to the base k1 is used as k1.

[0205] 22 is a diagram showing some of the RRC information elements related to HARQ-ACK timing information in embodiment 6.3. In this example, in addition to the base k1, k1-AI-Indicator-1 and k1-AI-Indicator-2, which are integer values ​​between 0 and 15, can be set. k1-AI-Indicator-1 and k1-AI-Indicator-2 do not have to be able to take values ​​in a wider range than the existing k1 (in FIG. 6).

[0206] Note that this number "15" is merely an example and may be another number [less than (or greater than) the upper limit of the existing k1 range (e.g., 15)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH.

[0207] <<Modifications>> In Embodiments 6.1 to 6.3, information on k1 is included in the RRC control element "PUCCH-Config." However, it may be configured by an RRC control element other than the RRC control element "PUCCH-Config," or may be defined in advance in a standard. Also, an RRC control element (e.g., dl-DataToUL-ACK-AI-Indicator) that is a list including information on k1 [for one or more AI indicators] may be configured in association with an AI indicator.

[0208] According to the sixth embodiment described above, k1 can be appropriately set to accommodate an increase in UE processing time due to AI conversion.

[0209] Seventh Embodiment The seventh embodiment relates to k2 of TDRA information of PUSCH.

[0210] In the seventh embodiment, control may be implemented to accommodate a wider range of k2 than the existing range of k2, taking into account, for example, the PDCCH demodulation / decoding time and PUSCH preparation time added by AI conversion.

[0211] In association with the AI ​​indicator, k2 may be configured / confirmed for the UE. In other words, the UE may determine k2 based on the AI ​​indicator. The AI ​​indicator in the description of the fifth embodiment may correspond to an AI indicator associated with a PDCCH (scheduling a PUSCH) or a PUSCH scheduled by the PDCCH.

[0212] The seventh embodiment can be broadly divided into the following three: - Embodiment 7.1: Extending the existing range (domain) of k2; - Embodiment 7.2: Introducing a new parameter for k2; - Embodiment 7.3: Introducing a new parameter that complements (constitutes) k2.

[0213] In the seventh embodiment, k2 may be interchangeably read as other parameters related to k2, such as k2-r16 (the seventh embodiment may be applied to these).

[0214] Furthermore, the RRC information elements / parameters / fields described hereinafter regarding the seventh embodiment may be given notations such as "-rXX (or -VXXXX)" corresponding to 3GPP release numbers (e.g., 3GPP Rel. 19) or existing notations may be overwritten. However, for simplicity, the following description will be given without any notations.

[0215] <<Embodiment 7.1>> In embodiment 7.1, the existing range (domain) of k2 may be extended. When instructing a UE of an AI indicator related to a PDCCH / PUSCH, the base station may control to use k2 indicated by the PDCCH (or a PDCCH corresponding to the PUSCH) in a range extended from the existing range.

[0216] k2 may be set in the UE according to existing rules, or may be set according to (or associated with) the AI ​​indicator for AI conversion.

[0217] 23 is a diagram illustrating a part of RRC information elements related to TDRA information of a PUSCH in embodiment 7.1. In this example, k2 is an integer value between 0 and 64, and can take a value in a wider range than the existing k2 (in FIG. 5).

[0218] Note that this number "64" is merely an example and may be another number [larger than the upper limit of the existing k2 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PUSCH.

[0219] <<Embodiment 7.2>> In embodiment 7.2, in addition to k2, k2 (for each AI indicator) for the case where an AI conversion is applied (e.g., k2 for AI indicator i may be referred to as k2-AI-Indicator-i) may be set. In this embodiment, k2 not related to an AI indicator (e.g., when an AI indicator is not set) may be referred to as an existing [defined in the standard] k2, a normal k2, a base k2, a default k2, etc.

[0220] Which setting of the configured base k2 and each k2-AI-Indicator-i is valid (which setting is actually used to determine the timing of the PUSCH) may depend on the configured AI indicator. For example, when AI indicator 1 is configured, k2-AI-Indicator-1 may be selected.

[0221] 24 is a diagram showing some of the RRC information elements related to TDRA information of the PUSCH in embodiment 7.2. In this example, in addition to the base k2, k2-AI-Indicator-1 and k2-AI-Indicator-2, which are integer values ​​between 0 and 64 and can take a wider range of values ​​than the existing k2 (in FIG. 5), can be set.

[0222] Note that this number "64" is merely an example and may be another number [larger than the upper limit of the existing k2 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PUSCH.

[0223] <<Embodiment 7.3>> In embodiment 7.3, k2 actually used to determine the timing of PUSCH is calculated based on k2 not related to the AI ​​indicator (e.g., when the AI ​​indicator is not set) and k2 (for each AI indicator) for the case where an AI conversion is applied (e.g., k2 for AI indicator i may be referred to as k2-AI-Indicator-i). In this embodiment, k2 not related to the AI ​​indicator may be referred to as an existing [standard-defined] k2, a normal k2, a base k2, a default k2, etc.

[0224] The k2 actually used to determine the timing of the PUSCH may be calculated by Equation 9. (Equation 9) k2 = base k2 + Σ(e ｉ *k2-AI-Indicator-i)

[0225] Here, ei is a value that depends on whether AI indicator i is set or not. For example, if AI indicator i is set, e ｉ = 1, otherwise e ｉ= 0. In other words, Equation 9 means that the value obtained by adding all the k2 values ​​for the set AI indicator i to the base k2 is used as k2.

[0226] 25 is a diagram showing some of the RRC information elements related to TDRA information of PUSCH in embodiment 7.3. In this example, in addition to the base k2, k2-AI-Indicator-1 and k2-AI-Indicator-2, which are integer values ​​between 0 and 32, can be set. k2-AI-Indicator-1 and k2-AI-Indicator-2 do not need to be able to take values ​​in a wider range than the existing k2 (in FIG. 5).

[0227] Note that this number "32" is merely an example and may be another number [less than (or greater than) the upper limit of the existing k2 range (e.g., 32)]. This number may be predefined, or may be determined based on parameters configured / instructed to the UE by higher layer signaling / physical layer signaling, or may be determined based on UE capabilities, or may be determined based on functionality / model / AI indicators associated with the PDCCH / PUSCH.

[0228] <<Modifications>> In Embodiments 7.1 to 7.3, information on k2 is included in the RRC control element "PUSCH-TimeDomainResourceAllocation." However, the information may be set by an RRC control element other than the RRC control element "PUSCH-TimeDomainResourceAllocation," or may be specified in advance in a standard. Furthermore, the RRC control element "PUSCH-TimeDomainResourceAllocationList" including information on k2 may be set in association with an AI indicator (e.g., for each AI indicator).

[0229] According to the seventh embodiment described above, k2 can be appropriately set to accommodate an increase in UE processing time due to AI conversion.

[0230] <Supplementary Information> <<Notification of Information to UE>> In the above-described embodiments, notification of any information to the UE [from a Network (NW) (e.g., a Base Station (BS))] (in other words, reception of any information from the BS by the UE) may be performed using physical layer signaling (e.g., DCI), higher layer signaling (e.g., RRC signaling, MAC CE), a specific signal / channel (e.g., PDCCH, PDSCH, reference signal), or a combination thereof.

[0245] (Wireless Communication System) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0246] 26 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 (which may be simply referred to as system 1) may be a system that realizes communication using Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) specified by the Third Generation Partnership Project (3GPP).

[0247] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0248] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (Master Node (MN)), and the NR base station (gNB) is the secondary node (Secondary Node (SN)). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0249] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0250] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The location, number, shape, size, etc. of each cell and user terminal 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as the base station 10.

[0251] 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 may be formed by multiple antennas / base stations 10. One [virtual] cell (which may be called, for example, a supercell) may be composed of multiple [virtual] cells (which may be called, for example, subcells). A supercell may correspond to a cell with a fixed physical range, and a subcell may correspond to a cell with a quasi-static / dynamically variable physical range. In this case, the wireless communication system 1 may be called a cell-free system.

[0252] 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).

[0253] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a higher frequency band than FR2.

[0254] 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.

[0255] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 / Xn interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0256] The base station 10 may be connected to the core network 30 directly or via another base station 10. The core network 30 may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

[0257] The core network 30 may include network functions (Network Functions (NF)) such as a User Plane Function (UPF), an Access and Mobility management Function (AMF), a Session Management Function (SMF), a Unified Data Management (UDM), an Application Function (AF), a Data Network (DN), a Location Management Function (LMF), and Operation, Administration and Maintenance (Management) (OAM). A single network node may provide multiple functions. Communication with an external network (e.g., the Internet) may also be performed via the DN.

[0258] The user terminal 20 may be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0259] An Orthogonal Frequency Division Multiplexing (OFDM)-based radio access scheme may be used in the wireless communication system 1. For example, Cyclic Prefix OFDM (CP-OFDM), Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), or the like may be used in at least one of the downlink (DL) and uplink (UL).

[0260] The radio access scheme may also be called a waveform. Note that in the wireless communication system 1, other radio access schemes (e.g., other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0261] In the wireless communication system 1, 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. may be used as the downlink channel.

[0262] Furthermore, in the wireless communication system 1, 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)), or the like may be used as an uplink channel.

[0263] The PDSCH transmits user data, higher layer control information, a System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit a Master Information Block (MIB).

[0264] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information for at least one of the PDSCH and the PUSCH.

[0265] Note that the DCI for scheduling the PDSCH may be referred to as a DL assignment, a DL DCI, etc., and the DCI for scheduling the PUSCH may be referred to as a UL grant, a UL DCI, etc. Note that the PDSCH may be replaced with DL data, and the PUSCH may be replaced with UL data.

[0266] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources for searching for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or more search spaces. The UE may monitor the CORESET associated with a certain search space based on the search space configuration.

[0267] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be referred to as a search space set. Note that the terms "search space," "search space set," "search space configuration," "search space set configuration," "CORESET," "CORESET configuration," and the like in the present disclosure may be read interchangeably.

[0268] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), delivery confirmation information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0269] In the present disclosure, downlink, uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning.

[0270] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, as the DL-RS, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted.

[0271] The synchronization signal may be, for example, at least one of a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). A signal block including an SS (PSS, SSS) and a PBCH (and a DMRS for the PBCH) may be referred to as an SS / PBCH block, an SS Block (SSB), or the like. Note that the SS, SSB, and the like may also be referred to as a reference signal.

[0272] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), or the like may be transmitted as an uplink reference signal (UL-RS). Note that the DMRS may also be called a user equipment-specific reference signal (UE-specific reference signal).

[0273] 27 is a diagram showing an example of the configuration of a base station according to an embodiment. The base station 10 includes a control unit 110, a transceiver unit 120, a transceiver antenna 130, and a transmission line interface 140. Note that the base station may include one or more of each of the control unit 110, the transceiver unit 120, the transceiver antenna 130, and the transmission line interface 140.

[0274] In this example, the functional blocks of the characteristic parts of the present embodiment are mainly shown, and it may be assumed that the base station 10 also has other functional blocks necessary for wireless communication. Some of the processing of each unit described below may be omitted.

[0275] The control unit 110 performs overall control of the base station 10. The control unit 110 can be configured from a controller, a control circuit, and the like that are explained based on common understanding in the technical field to which the present disclosure relates.

[0276] The control unit 110 may control signal generation, scheduling (e.g., resource allocation, mapping), etc. The control unit 110 may control transmission and reception using the transceiver unit 120, the transceiver antenna 130, and the transmission path interface 140, measurement, etc. The control unit 110 may generate data, control information, sequences, etc. to be transmitted as signals, and transfer them to the transceiver unit 120. The control unit 110 may perform call processing (setting up, releasing, etc.) of communication channels, status management of the base station 10, management of radio resources, etc.

[0277] The transceiver unit 120 may include a baseband unit 121, a radio frequency (RF) unit 122, and a measurement unit 123. The baseband unit 121 may include a transmission processing unit 1211 and a reception processing unit 1212. The transceiver unit 120 may be configured with a transmitter / receiver, an RF circuit, a baseband circuit, a filter, a phase shifter, a measurement circuit, a transceiver circuit, etc., which are described based on common understanding in the technical field related to the present disclosure.

[0278] The transmitting / receiving unit 120 may be configured as an integrated transmitting / receiving unit, or may be configured from a transmitting unit and a receiving unit. The transmitting unit may be configured from a transmission processing unit 1211 and an RF unit 122.

[0295] In this example, the functional blocks of the characteristic parts of the present embodiment are mainly shown, and it may be assumed that the user terminal 20 also has other functional blocks necessary for wireless communication. Some of the processing of each unit described below may be omitted.

Note that in the present disclosure, CSI-RS, NZP CSI-RS, ZP CSI-RS, CSI-IM, CSI-SSB, etc. may be interchangeably read as interchangeable.

[0311] The transmitting unit and receiving unit of the user terminal 20 in the present disclosure may be configured by at least one of the transmitting / receiving unit 220 and the transmitting / receiving antenna 230.

[0320] (Hardware Configuration) Note that the block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices. The functional block may be realized by combining software with the single device or the multiple devices.

[0321] Here, the functions include, but are not limited to, judgment, determination, judgment, calculation, computation, processing, derivation, investigation, search, confirmation, reception, transmission, output, access, resolution, selection, election, establishment, comparison, assumption, expectation, deeming, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assignment. For example, a functional block (component) that performs transmission may be called a transmitting unit, transmitter, etc. As described above, the implementation method of each is not particularly limited.

[0322] For example, a base station, a user terminal, etc. according to an embodiment of the present disclosure may function as a computer that performs processing of the wireless communication method of the present disclosure. Figure 29 is a diagram illustrating an example of the hardware configuration of a base station and a user terminal according to an embodiment. The above-described base station 10 and user terminal 20 may 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, a bus 1007, etc.

[0323] In the present disclosure, the terms apparatus, circuit, device, section, unit, etc. may be used interchangeably. The hardware configurations of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the drawings, or may be configured to exclude some of the devices.

[0324] For example, although only one processor 1001 is shown, there may be multiple processors. Furthermore, processing may be performed by one processor, or processing may be performed by two or more processors simultaneously, serially, or in other ways. Furthermore, processor 1001 may be implemented by one or more chips.

[0325] Each function in the base station 10 and the user terminal 20 is realized, for example, by loading specified software (programs) onto hardware such as a processor 1001 and a memory 1002, causing the processor 1001 to perform calculations, control communication via the communication device 1004, and control at least one of reading and writing data in the memory 1002 and the storage 1003.

[0326] The processor 1001, for example, runs an operating system to control the entire computer. The processor 1001 may be configured as a central processing unit (CPU) including an interface with peripheral devices, a control device, an arithmetic unit, a register, etc. For example, at least a part of the above-mentioned control unit 110 (210), transceiver unit 120 (220), etc. may be realized by the processor 1001.

[0327] The processor 1001 also reads programs (program codes), 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 in accordance with these. The programs used are those that cause a computer to execute at least some of the operations described in the above-described embodiments. 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 the other functional blocks may be implemented in a similar manner.

[0328] The memory 1002 is a computer-readable recording medium and may be configured by at least one of, for example, Read Only Memory (ROM), Erasable Programmable ROM (EPROM), Electrically EEPROM (EEPROM), Random Access Memory (RAM), or other suitable storage medium. The memory 1002 may also be referred to as a register, cache, main memory, etc. The memory 1002 may store executable programs (program codes), software modules, etc. for implementing a wireless communication method according to an embodiment of the present disclosure.

[0329] Storage 1003 is a computer-readable recording medium and may be composed of at least one of, for example, a flexible disk, a floppy disk, a magneto-optical disk (e.g., a compact disc (e.g., a Compact Disc ROM (CD-ROM)), a digital versatile disc, a Blu-ray disc), a removable disk, a hard disk drive, a smart card, a flash memory device (e.g., a card, a stick, a 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.

[0330] The communication device 1004 is hardware (transmission / reception device) for communicating between computers via at least one of a wired network and a wireless network, and is also referred to as, for example, a network device, a network controller, a network card, or a communication module. The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0331] The input device 1005 is an input device (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that accepts input from the outside. The output device 1006 is an output device (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.) that outputs to the outside. Note that the input device 1005 and the output device 1006 may be integrated into one device (e.g., a touch panel).

[0332] Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0333] 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), or a field programmable gate array (FPGA), and some or all of the functional blocks may be realized using this hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0334] In addition, the devices included in the core network 30 (for example, network nodes that provide NF) may also be realized by the above-mentioned functional block / hardware configuration.

[0335] (Modifications) Note that terms described in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applicable standard. A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0336] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0337] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by a transceiver in the frequency domain, and specific windowing performed by a transceiver in the time domain.

[0338] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may also be a time unit based on numerology.

[0339] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0340] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0341] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0342] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0343] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0344] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0345] A TTI having a time length of 1 ms may be called a regular TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0346] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and greater than or equal to 1 ms.

[0347] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0348] In addition, an RB may include one or more symbols in the time domain and may have a length of one slot, one minislot, one subframe, or one TTI, each of which may be composed of one or more resource blocks.

[0349] In addition, one or more RBs may be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0350] 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.

[0351] A Bandwidth Part (BWP), which may also be referred to as a partial bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0352] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0353] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0354] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0355] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

[0356] The names used for parameters and the like in this disclosure are not intended to be limiting in any way. Furthermore, the mathematical expressions and the like using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

[0357] The information, signals, etc. described in this disclosure may be represented using any of a variety of different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0358] Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via multiple network nodes.

[0359] Input and output information, signals, etc. may be stored in a specific location (for example, memory) or may be managed using a management table. Input and output information, signals, etc. may be overwritten, updated, or added. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

[0360] With respect to any information (e.g., variables, constants, parameters) described in the present disclosure, even if not specifically stated in the above embodiments, any first device (e.g., UE / base station) may notify any second device (e.g., base station / UE) of information indicating / specifying (or relating to) the value of the any information.

[0361] The notification of information is not limited to the aspects / embodiments described in the present disclosure, and may be performed using other methods. For example, the notification of information in the present disclosure may be performed by physical layer signaling (e.g., Downlink Control Information (DCI) and Uplink Control Information (UCI)), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB) and System Information Block (SIB)), Medium Access Control (MAC) signaling), other signals, or a combination thereof.

[0362] Note that the physical layer signaling may be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. Furthermore, the RRC signaling may be referred to as an RRC message, such as an RRC Connection Setup message or an RRC Connection Reconfiguration message. Furthermore, the MAC signaling may be notified using, for example, a MAC Control Element (CE).

[0363] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0364] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value represented by true or false, or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).

[0365] Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.

[0366] Software, instructions, information, etc. may also be transmitted or received over a transmission medium.
