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.

[0005] In future wireless communication systems (e.g., NR), improvements in coverage are being considered.

[0006] However, if the reports on the terminal's transmission power are not thoroughly considered, it may result in a reduction in coverage, a deterioration in communication quality, a decrease in throughput, and the like.

[0007] Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and a base station that appropriately report on the transmission power of the terminal.

[0008] A terminal according to one aspect of the present disclosure includes a transmitter that transmits a report based on a waveform of an uplink transmission, and a controller that controls the uplink transmission based on the report.

[0009] According to one aspect of the present disclosure, it is possible to appropriately report on the transmission power of a terminal.

[0011] (PUSCH transmission power control) In NR, the transmission power of the PUSCH is controlled based on the TPC command (also called a value, an increase / decrease value, a correction value, etc.) indicated by the value of a field in the DCI (also called a TPC command field, etc.).

[0012] For example, when a UE transmits a PUSCH on an active UL BWP b of a carrier f of a serving cell c using a parameter set (open loop parameter set) with index j and a power control adjustment state (PUSCH power control adjustment state) with index l, the transmission power (P ＰＵＳＣＨ、ｂ，ｆ，ｃ (i, j, q ｄ , l)) [dBm] is expressed as follows: ＣＭＡＸ，ｆ，ｃ（ｉ） , P Ｏ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ (j), M ＰＵＳＣＨ ＲＢ，ｂ，ｆ，ｃ (i), α ｂ，ｆ，ｃ (j), P.L. ｂ，ｆ，ｃ (q ｄ ), Δ ＴＦ，ｂ，ｆ，ｃ (i), f ｂ，ｆ，ｃ (i, l), may be based on at least one of

[0013]

[0014] The power control adjustment state may be referred to as a closed loop (CL)-power control (PC) state, a value based on TPC commands of a power control adjustment state index l, an accumulated value of TPC commands, or a value due to closed loop, where l may be referred to as a closed loop index.

[0015] Furthermore, the PUSCH transmission opportunity i is a period during which the PUSCH is transmitted, and may be composed of, for example, one or more symbols, one or more slots, etc.

[0016] P ＣＭＡＸ，ｆ，ｃ(i) is, for example, the maximum transmit power of the user terminal configured for carrier f of serving cell c at transmission opportunity i (configured maximum output power, UE configured maximum output power).

[0017] P Ｏ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ (j) is, for example, a parameter related to the target received power (e.g., a parameter related to the transmit power offset, also referred to as a transmit power offset P0, a target received power parameter, etc.) set for the active UL BWP b of the carrier f of the serving cell c at the transmission opportunity i. Ｏ＿ＵＥ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ (j) is P Ｏ＿ＮＯＭＩＮＡＬ＿ＰＵＳＣＨ，ｆ，ｃ (j) and P Ｏ＿ＵＥ＿ＰＵＳＣＨ，ｂ，ｆ，ｃ It may be the sum of (j).

[0018] M ＰＵＳＣＨ ＲＢ，ｂ，ｆ，ｃ (i) is the number of resource blocks (bandwidth) allocated to PUSCH for transmission opportunity i in active UL BWP b of carrier f with serving cell c and subcarrier spacing μ, for example. ｂ，ｆ，ｃ (j) is a value provided by a higher layer parameter (e.g., also called msg3-Alpha, p0-PUSCH-Alpha, fractional factor, etc.).

[0019] PL ｂ，ｆ，ｃ (q ｄ ) is, for example, an index q of a reference signal (RS, pathloss reference RS, pathloss (PL)-RS, pathloss reference RS, pathloss measurement DL-RS, PUSCH-PathlossReferenceRS) for downlink BWP associated with an active UL BWP b of carrier f of serving cell c. ｄ is the path loss (path loss estimation [dB], path loss compensation) calculated by the user terminal using

[0020] If the UE is not provided with a pathloss reference RS (e.g., PUSCH-PathlossReferenceRS) or if the UE is not provided with individual upper layer parameters, the UE may use RS resources from a synchronization signal (SS) / physical broadcast channel (PBCH) block (SS block (SSB)) used to obtain a Master Information Block (MIB). ｂ，ｆ，ｃ (q ｄ ) may be calculated.

[0021] When the UE is configured with a number of RS resource indices up to the value of the maximum number of pathloss reference RSs (e.g., maxNrofPUSCH-PathlossReferenceRSs) and a set of RS configurations for the RS resource indices according to the pathloss reference RSs, the set of RS resource indices may include one or both of a set of SS / PBCH block indices and a set of channel state information (CSI)-reference signal (RS) resource indices. ｄ may be identified.

[0022] If a PUSCH transmission is scheduled by a Random Access Response (RAR) UL grant, the UE uses the same RS resource index q as for the corresponding PRACH transmission. ｄ may also be used.

[0023] When a UE is provided with a power control configuration for the PUSCH by a sounding reference signal (SRS) resource indicator (SRI) (e.g., SRI-PUSCH-PowerControl) and with one or more values ​​of ID of the pathloss reference RS, the UE may obtain a mapping between a set of values ​​for the SRI field in DCI format 0_1 ​​and a set of ID values ​​of the pathloss reference RS from higher layer signaling (e.g., sri-PUSCH-PowerControl-Id in SRI-PUSCH-PowerControl). The UE may obtain the RS resource index q from the ID of the pathloss reference RS mapped to the SRI field value in DCI format 0_1 ​​that schedules the PUSCH. ｄ may be determined.

[0024] If a PUSCH transmission is scheduled by DCI format 0_0 and the UE is not provided with PUCCH spatial relationship information for the PUCCH resource with the lowest index for the active UL BWP b of each carrier f and serving cell c, the UE shall transmit the PUCCH spatial relationship information for the PUCCH resource with the same RS resource index q as the PUCCH transmission in that PUCCH resource. ｄ may also be used.

[0025] If the PUSCH transmission is scheduled by DCI format 0_0 and the UE is not provided with a spatial setting for the PUCCH transmission, or if the PUSCH transmission is scheduled by DCI format 0_1 ​​that does not include an SRI field, or if the UE is not provided with a power control setting for the PUSCH by the SRI, the UE shall select an RS resource index q with an ID of a path loss reference RS of zero. ｄ may also be used.

[0026] For PUSCH transmission configured by a configured grant configuration (e.g., ConfiguredGrantConfig), if the configured grant configuration includes a specific parameter (e.g., rrc-ConfiguredUplinkGrant), the RS resource index q is determined by a path loss reference index (e.g., pathlossReferenceIndex) in the specific parameter. ｄ may be provided to the UE.

[0027] For the PUSCH transmission configured by the configuration grant configuration, if the configuration grant configuration does not include a specific parameter, the UE may determine the RS resource index q from the value of the ID of the path loss reference RS mapped to the SRI field in the DCI format that activates the PUSCH transmission. ｄ If the DCI format does not include an SRI field, the UE may determine an RS resource index q with an ID of a pathloss reference RS of zero. ｄ may be determined.

[0028] Δ ＴＦ，ｂ，ｆ，ｃ (i) is the transmission power adjustment component (offset, transmission format compensation) for UL BWP b of carrier f of serving cell c.

[0029] f ｂ，ｆ，ｃ (i, l) is the PUSCH power control adjustment state for the active UL BWP b of carrier f of serving cell c at transmission opportunity i. ｂ，ｆ，ｃ (i,l) may be based on δPUSCH,b,f,c(i,l).

[0030] If TPC accumulation is valid, f ｂ，ｆ，ｃ (i,l) may be based on the accumulated value of δPUSCH,b,f,c(m,l).

[0031] If TPC accumulation is invalid, f ｂ，ｆ，ｃ (i,l) may be δPUSCH,b,f,c(i,l) (absolute value).

[0032] If information indicating that TPC accumulation is disabled (TPC-Accumulation) is not set (if information indicating that TPC accumulation is disabled is not provided, and TPC accumulation is set to be enabled), the UE accumulates TPC command values ​​and determines the transmit power based on the accumulation result (power control state) (applies the TPC command values ​​via accumulation).

[0033] When information indicating that TPC accumulation is disabled (TPC-Accumulation) is set (when information indicating that TPC accumulation is disabled is provided, when TPC accumulation is set to disabled), the UE does not accumulate TPC command values ​​and determines the transmission power based on the TPC command values ​​(power control state) (applies the TPC command values ​​without using accumulation).

[0034] δPUSCH,b,f,c(i,l) may be the TPC command value included in DCI format 0_0 or DCI format 0_1 ​​that schedules PUSCH transmission opportunity i on active UL BWP b of carrier f of serving cell c, or the TPC command value jointly coded with other TPC commands in DCI format 2_2 with CRC scrambled by a specific Radio Network Temporary Identifier (RNTI) (e.g., TPC-PUSCH-RNTI).

[0035] Σ m=0 C(Di)-1 δPUCCH,b,f,c(m,l) is the cardinality C(D i ) a set of TPC command values ​​D i It may be the sum of the TPC command values ​​in i is the number of PUSCH transmission opportunities i-i0 on the active UL BWP b of carrier f of serving cell c for the PUSCH power control adjustment state l. PUSCH (i-i0)-1 symbols ago and K of PUSCH transmission opportunity i PUSCH (i) may be the set of TPC command values ​​received between symbols (i) and (ii) for PUSCH transmission opportunity i-i. PUSCH(i-i0) symbols ago is K of PUSCH transmission opportunity i PUSCH (i) It may be the smallest positive integer that is earlier than the symbol before.

[0036] If PUSCH transmission is scheduled by DCI format 0_0 or DCI format 0_1, K PUSCH (i) may be the number of symbols in the active UL BWP b of carrier f of serving cell c after the last symbol of the corresponding PDCCH reception and before the first symbol of the PUSCH transmission. If PUSCH transmission is configured by configured grant configuration information (ConfiguredGrantConfig), then K PUSCH (i) is the number of symbols per slot N in the active UL BWP b of carrier f of serving cell c symb slot and the minimum value of the value provided by k2 in the PUSCH common configuration information (PUSCH-ConfigCommon). PUSCH,min It may also be the number of symbols.

[0037] The power control adjustment state may be configured to have multiple states (e.g., two states) or a single state depending on a higher layer parameter. When multiple power control adjustment states are configured, one of the multiple power control adjustment states may be identified by an index l (e.g., l∈{0, 1}).

[0038] The transmission power of the PUCCH, the transmission power of the SRS, and the transmission power of the PUSCH are set to the maximum output power P ＣＭＡＸ，ｆ，ｃ（ｉ） is limited by

[0039] (Nominal maximum output power / set maximum output power) The UE power class specifies the maximum output power (nominal maximum output power, nominal UE power, UE maximum output power) for the transmission bandwidth within the channel bandwidth of the NR carrier.

[0040] As an example in Figure 1, a nominal maximum output power P_PowerClass is defined for each UE power class and band. Power Class 1 is defined for public safety only. Power Class 1.5 is defined for UEs with dual transmission (Tx). Power Class 2 is defined for high power UEs. Power Class 3 is defined for handheld cellular UEs.

[0041] Class 3, with 23 dBm, is the default power class, which is derived based on a specific absorption rate (SAR) assumption that 100% of a resource is used for UL transmission.

[0042] The settings (upper and lower bounds) of P_CMAX are defined by the following equation:

[0043]

[0044] where P_EMAX,c is the value given by the p-Max information element or additionalPmax for serving cell c (maximum allowed UE output power signaled by higher layers), and ΔP_PowerClass is the adjustment to the nominal maximum output power P_PowerClass for a given power class, which is a duty cycle dependent power constraint.

[0045] In any of the following states (conditions) 1 to 4, P_PowerClass>0. If the state is not any of states 1 to 4, P_PowerClass=0.

[0046] [State 1] If any of the following conditions are met, ΔP_PowerClass=3 dB for a Power Class (PC) 2 UE and ΔP_PowerClass=6 dB for a PC1.5 UE: ​​- A p-Max of 23 dBm or less is indicated; - The UECapabilitymaxUplinkDutyCycle-PC2-FR1 field is not present, the UECapabilitymaxUplinkDutyCycle-MPE-FR1 field is not present, and the percentage of UL symbols transmitted within a certain evaluation period is higher than 50%; - The UECapabilitymaxUplinkDutyCycle-PC2-FR1 field is present, and the percentage of UL symbols transmitted within a certain evaluation period is higher than maxUplinkDutyCycle-PC2-FR1 (the exact evaluation period is shorter than one radio frame). The field UE capability maxUplinkDutyCycle-MPE-FR1 is present and the percentage of UL symbols transmitted in an evaluation period is higher than maxUplinkDutyCycle-MPE-FR1 (the exact evaluation period is shorter than one radio frame).

[0047] State 2: ΔP_PowerClass=3 dB for a PC1.5 UE if any of the following conditions are met: A p-Max between 23 dBm and 26 dBm is indicated; The UECapabilitymaxUplinkDutyCycle-PC2-FR1 field is not present, the UECapabilitymaxUplinkDutyCycle-MPE-FR1 field is not present, and the percentage of UL symbols transmitted within a certain evaluation period is between 25% and 50%; The UECapabilitymaxUplinkDutyCycle-PC2-FR1 field is present, and the percentage of UL symbols transmitted within a certain evaluation period is between maxUplinkDutyCycle-PC2-FR1 and maxUplinkDutyCycle-PC2-FR1 / 2 (the exact evaluation period is shorter than one radio frame). The field UE capability maxUplinkDutyCycle-MPE-FR1 is present and the percentage of UL symbols transmitted in an evaluation period is higher than maxUplinkDutyCycle-MPE-FR1 (the exact evaluation period is shorter than one radio frame).

[0048] [State 3] If the UE is configured with supplemental uplink (SUL) configuration and in the band in which the UE exhibits power class 2, the default power class requirements specified in the specification apply, then ΔP_PowerClass=3 dB.

[0049] [State 4] If a PC2 capable UE with transmit diversity (txDiversity-r16) capability or a PC1.5 capable UE indicates SRS transmit switch (SRS-TXSwitch) capability 't1r2' or 't1r4' or 't1r1-t1r2' or 't1r1-t1r2-t1r4', then ΔP_PowerClass=3dB applies during SRS transmission occasions with SRS resources configured in each SRS resource set consisting of one SRS port and with usage in the SRS-ResourceSet set to 'antennaSwitching'.

[0050] Rel. 17 NR defines a high-power UE, which can transmit using power greater than 23 dBm. 23 dBm is considered the default PC (PC3). 23 dBm is derived based on the SAR requirement when the UE transmits UL on 100% of a given resource.

[0051] (Transmission Power Upper Limit in CA and DC) A UE that indicates the capability of dynamic power sharing can set the total maximum transmission power P_Total^EN-DC (P_Total) in EN-DC. The total maximum transmission power is based on the set value P_EMAX,EN-DC (p-maxUE-FR1) and the power class-based value P_PowerClass,EN-DC - ΔP_PowerClass,EN-DC. As in the example of Figure 2, if the sum of the NR transmission power P_NR and the E-UTRA transmission power P_LTE exceeds the total maximum transmission power P_Total, the NR transmission power is limited until the sum becomes equal to or less than P_Total.

[0052] Increasing the UE power limits for carrier aggregation (CA) and dual connectivity (DC) is being considered.

[0053] For example, in inter-band CA, it is considered that P_CMAX for the entire CA transmission is extended to utilize the full nominal maximum available output power according to the UE capabilities (e.g., HigherPowerLimitCADC). That is, P_PowerClass is replaced by 10log10ΣP_PowerClass,c, where P_PowerClass,c is the P_PowerClass of each band.

[0054] For example, in inter-band E-UTRAN / NR(EN)-DC, it is being considered that P_CMAX for the entire CA transmission be extended to utilize the full nominal maximum available output power in accordance with the UE capabilities (e.g., HigherPowerLimitCADC). That is, P_PowerClass is replaced by the value obtained by converting the sum of the linear values ​​of P_PowerClass,NR and P_PowerClass,E-UTRA to dB, where P_PowerClass,NR is the P_PowerClass for NR and P_PowerClass,E-UTRA is the P_PowerClass for E-UTRA.

[0055] In this disclosure, utilizing all of the available nominal maximum output power may be referred to as high-power CA / DC UL transmission.

[0056] The following items are considered for the functionality: - Amount of UL resources during the evaluation period - Whether supplemental uplink (SUL) is configured - Whether UL transmission is SRS with antenna switching.

[0057] To enable high power CA / DC UL transmission, it is preferable that ΔP_PowerClass=0 as mentioned above.

[0058] Here, it is assumed that the maximum output power of CC#1 (band#1) is 26 dBm and the maximum output power of CC#2 (band#2) is 23 dBm.

[0059] If a separate power amplifier (PA) is implemented for each CC / band, the total maximum technically possible output power is 27.76 dBm, assuming full power for each CC.

[0060] Prior to Rel. 16, if the CA / DC power class is PC3, the total maximum output power is 23 dBm, and if the CA / DC power class is PC2, the total maximum output power is 26 dBm. As shown in the example of Figure 3A, a total maximum output power higher than 26 dBm is not permitted.

[0061] In Rel. 17, when the CA / DC power class is PC3, the total maximum output power is 23 dBm, and when the CA / DC power class is PC2, the total maximum output power is 26 dBm. As shown in the example of Figure 3B, when the CA / DC power class is PC2 and the UE reports a capability (HigherPowerLimitCADC), the total maximum output power is 27.76 dBm.

[0062] (PHR) Power headroom reporting (PHR) can be any of types 1 to 3, Maximum Permissible Exposure (MPE) or Power Management Maximum Power Reduction (P-MPR) reporting. Type 1 provides the serving gNB with the difference between the nominal maximum output power and the power estimated for UL-SCH transmission for each activated serving cell. Type 2 provides the serving gNB with the difference between the nominal maximum output power and the power estimated for UL-SCH and PUCCH transmissions on the SpCell of another MAC entity. Type 3 provides the serving gNB with the difference between the nominal maximum output power and the power estimated for SRS transmission for each activated serving cell. MPE P-MPR provides power backoff to the serving gNB to meet MPE FR2 requirements for serving cells operating on FR2.

[0063] PHR is triggered based on at least one of the following: expiration of the PHR prohibition timer (phr-ProhibitTimer), a change in path loss (threshold phr-Tx-PowerFactorChange), expiration of the PHR periodic timer (phr-PeriodicTimer), activation of an SCell, activation of an SCG, addition of a PSCell, the MAC entity having UL resources for transmission, a change in the required power backoff (threshold phr-Tx-PowerFactorChange), switching of the BWP of the SCell, configuration of MPE FR2 reporting (mpe-Reporting-FR2), and the measured P-MPR (threshold phr-Tx-PowerFactorChange).

[0064] If multiple PHR is set, the multiple entry PHR is used; otherwise, the single entry PHR is used.

[0065] The PHR may be transmitted by Medium Access Control (MAC) signaling using a Physical Uplink Shared Channel (PUSCH). For example, the PHR is notified using a PHR MAC Control Element (CE) included in a MAC Protocol Data Unit (PDU).

[0066] In NR, a single entry PHR MAC CE for the primary cell (PCell) is supported.

[0067] 4 shows an example of a single-entry PHR MAC CE in Rel. 15 / 16 NR. This MAC CE consists of two octets (= 16 bits). This MAC CE includes the fields R, PH, P, P_CMAX, f, c, and MPE.

[0068] Each 'R' indicates a 1-bit reserved field, which is set to a value of '0', for example.

[0069] 'PH (Type 1, PCell)' is a 6-bit field indicating an index for a Type 1 PH of the primary cell (PCell). The index for the PH is associated with a specific PH value (in decibels (dB)) (or level).

[0070] For example, Type 1 PH may be a PH when taking into consideration the PUSCH (e.g., taking into consideration only the power of the PUSCH), Type 2 PH may be a PH when taking into consideration the PUCCH (e.g., taking into consideration the power of both the PUSCH and the PUCCH), and Type 3 PH may be a PH when taking into consideration a measurement reference signal (Sounding Reference Signal (SRS)) (e.g., taking into consideration the power of the PUSCH and the SRS).

[0071] 'P ＣＭＡＸ，ｆ，ｃ ' indicates a 6-bit field, and is the P used in calculating the PH field above. ＣＭＡＸ，ｆ，ｃ The index for the P ＣＭＡＸ，ｆ，ｃ The index for P is associated with a specific UE transmit power level (dB). ＣＭＡＸ，ｆ，ｃ may be referred to as the configured maximum transmit power (maximum allowed transmit power) for serving cell c of carrier f. ＣＭＡＸ，ｆ，ｃ is simply P ＣＭＡＸ , PCMAX, etc.

[0072] 'P' may be a field related to Power Management Maximum Power Reduction (P-MPR) or Maximum Permitted UE Output Power Reduction for the serving cell c, or may be a field related to Maximum Permitted Exposure (MPE). 'MPE' may be a field related to MPE. Fields such as 'P' and 'MPE' may be replaced with an 'R' field depending on the configuration using higher layer signaling to the UE.

[0073] The 'P' field is set to FR2 MPE reporting (upper layer parameter mpe-Reporting-FR2), and if the serving cell operates in FR2, it is set to 0 if the P-MPR value applied to meet the MPE requirement is less than a specific P-MPR value (e.g., P-MPR_00), otherwise it is set to 1.

[0074] Also, the 'P' field may indicate whether power backoff is applied for power management when FR2 MPE reporting is not configured or when the serving cell operates in FR1. If power backoff is not applied for power management, the corresponding P ＣＭＡＸ If the fields were to have different values, the 'P' field is set to one.

[0075] The 'MPE' field may indicate the power backoff to be applied to satisfy the MPE requirement if MPE reporting for FR2 (higher layer parameter mpe-Reporting-FR2) is set, the serving cell operates in FR2, and the 'P' field is set to 1. This field may indicate an index corresponding to the measured P-MPR value (e.g., in dB).

[0076] If FR2 MPE reporting is not configured, or the serving cell is operating in FR1, or the 'P' field is set to 0, the R field (R bit) may be present instead of the 'MPE' field.

[0077] In NR, a multiple entry PHR MAC CE that includes multiple pieces of data similar to the above-mentioned single entry (2 octets) is also supported. The multiple entry PHR MAC CE may include a PH field for a primary secondary cell (PSCell) and a secondary cell (SCell). Note that the PCell and PSCell may be referred to as special cells (SpCells).

[0078] 5 shows an example of a multiple-entry PHR MAC CE in Rel. 15 / 16 NR. This MAC CE includes the following fields: C_i, R, V, PH, P, P_CMAX, f, c, and MPE. Fields similar to those in the single-entry PHR MAC CE will not be described again.

[0079] The 6-bit field of 'PH' indicates the corresponding type (eg, types 1-3 above) and PH field for the cell.

[0080] Note that the presence of the Type 2 PH field for the SpCell of another MAC entity may be set by the higher layer parameter phr-Type2OtherCell being true.

[0081] 'P ＣＭＡＸ，ｆ，ｃ The 6-bit field of ' is the P used in calculating the previous PH field. ＣＭＡＸ，ｆ，ｃ P indicates ＣＭＡＸ，ｆ，ｃ It is a field. ｉ ' is a field indicating whether the PH field of the serving cell corresponding to the serving cell index i is included in the PHR. Note that the example in this figure is for the case where the maximum serving cell index is less than 8. If it is 8 or more, the MAC CE can indicate serving cells up to i=31, for example. ｉ ' field may be included.

[0082] The number and P assigned to the "serving cell" in the PH field ＣＭＡＸ，ｆ，ｃ The number in the field may not necessarily mean the serving cell index, but may simply mean the ordinal number of the value included in the MAC CE.

[0083] 'V' is a field that indicates whether the PH value corresponding to the immediately following PH field is based on real transmission (V=0) or on a reference format (V=1). A PH based on a reference format may be called a virtual PH. Note that when V=1, the corresponding 'PＣＭＡＸ，ｃ The ', 'MPE' fields, etc. may be omitted.

[0084] The network may transmit PHR configuration information to the UE regarding the conditions for triggering PHR, such as a prohibit timer, a periodic timer, and a path loss change threshold. This notification may be performed via higher layer signaling. The UE triggers PHR when the PHR trigger conditions are met.

[0085] As shown in the example of Figure 6, the specification defines a mapping between PH values ​​and the values ​​(range) of the measured quantity. As shown in the example of Figure 7, the specification defines a mapping between P_CMAX values ​​and the values ​​(range) of the measured quantity. As shown in the example of Figure 8, the specification defines a mapping between the reported value of FR2 P-MPR and the values ​​(range) of the measured quantity.

[0086] Dynamic UL Waveform Switching Extensions are being considered to support dynamic switching between multiple waveforms, which may include DFT-S-OFDM and CP-OFDM.

[0087] Both DFT-S-OFDM and CP-OFDM are supported as waveforms for the PUSCH of NR. The waveforms are switched by an RRC IE. Both waveforms have their own advantages. When CP-OFDM is used, frequency resource allocation becomes more flexible. Both contiguous and non-contiguous PRB allocations are allowed. PRB allocation is not limited to multiples of 2, 3, or 5. DMRS and PUSCH are FDM-modulated. When DFT-S-OFDM is used, the peak to average power ratio (PAPR) is lower. The network (NW) switches waveforms based on the signal to noise ratio (SNR). To switch, an RRC reconfiguration message is required.

[0088] Generally, the coverage of DFT-S-OFDM is wider than that of CP-OFDM. When determining the transmission power, it is necessary to take into account the backoff value relative to the PAPR. In CP-OFDM, a larger backoff value is used because of the higher PAPR.

[0089] In the existing specifications, the UE determines P_CMAX,f,c (the set maximum output power) by considering the above equation (2). At the lower limit P_CMAX,f,c, MPR_c is considered.

[0090] In the existing specifications, MPR is defined for waveforms, modulations, and RB arrangements as shown in Figure 9. The actual MPR value depends on the UE implementation, i.e., the base station cannot know the actual MPR value.

[0091] As previously mentioned, the PHR provides the serving base station with the difference between the nominal UE maximum transmit power and the estimated power for UL transmission. As previously mentioned, the PHR is generally triggered / initiated by the UE.

[0092] However, it is unclear whether dynamic UL waveform switching is beneficial to base stations / networks. If reports are not carefully considered, it may result in reduced coverage, poor communication quality, and reduced throughput.

[0093] Therefore, the present inventors came up with the idea of ​​a method for reporting the transmission power of a terminal.

[0117] The RB allocation (RB allocation type) may be defined as follows: Start,Low ≦RB Start ≦RB Start,High and LCRB ≦ceil(N RB / 2) is satisfied, the RB allocation may be an inner RB allocation. An edge RB allocation is when one or more RBs are allocated to channel L. CRB The RB allocation may be an outer RB allocation for all other allocations that are not inner RB allocations or edge RB allocations.

[0118] --Option 2: Multiple Values ​​of Actual MPR With this information, the NW can know the actual MPR taking into account the dynamically commanded waveform.

[0119] ---Option 1 Each value of the multiple values ​​may follow at least one of several options in Option 1.

[0120] --Option 3: Difference Between Multiple P_CMAX Values ​​--Option 1 Each value of the multiple P_CMAX values ​​may follow at least one of several options in Option 1.

[0121] ---Option 2 The calculation of the difference may follow at least one of the following options: The multiple P_CMAX values ​​may include P_CMAX1, P_CMAX2. P_CMAX1 and P_CMAX2 may correspond to CP-OFDM and DFT-S-OFDM, respectively. The correspondence may be reversed from this example.

[0122] ---Option 2-1: Absolute value of (P_CMAX1-P_CMAX2) This calculation allows for reduction of reporting overhead by considering only positive values ​​or 0.

[0123] ---Option 2-2: (P_CMAX1-P_CMAX2) Technically, Option 2-2 is equivalent to Option 2-1.

[0124] --Option 3a: The difference between multiple P_CMAX values ​​is greater than or equal to a threshold. The threshold may be defined in the specification, configured by the RRC, indicated by the MAC CE, or indicated by the DCI.

[0125] --Option 4: Difference Between Multiple MPR Values ​​--Option 1 Each value of the multiple MPR values ​​may follow at least one of several options in Option 1.

[0126] ---Option 2 The calculation of the difference may follow at least one of the following options: The multiple MPR values ​​may include MPR1 and MPR2. MPR1 and MPR2 may correspond to CP-OFDM and DFT-S-OFDM, respectively. The correspondence may be reversed from this example.

[0130] Option 5: Recommendation from the UE regarding whether DFT-S-OFDM is beneficial or not. For example, one bit may be reported. A value of '0' for that bit may mean that DFT-S-OFDM is more beneficial than CP-OFDM for a certain performance. A value of '1' for that bit may mean that DFT-S-OFDM is less beneficial than CP-OFDM for a certain performance. The meaning of the value of the bit may also be reversed from this example.

[0131] The interpretation of the recommendation (specific performance) may follow at least one of several options:

[0132] ---Option 1 The specific performance may be PAPR performance.

[0133] ---Option 2 The specific performance may be the actual MPR value. For example, a value of '0' for the bit may mean that the actual MPR value is equal to or greater than the threshold, and a value of '1' for the bit may mean that the actual MPR value is less than the threshold. The meaning of the bit value may be reversed from this example.

[0134] ---Option 3 The specific performance may be the actual MPR value for DFT-S-OFDM / CP-OFDM. For example, a value of '0' for the bit may mean that the actual MPR value for CP-OFDM is equal to or greater than a threshold, and a value of '1' for the bit may mean that the actual MPR value for CP-OFDM is less than the threshold. The meaning of the value of the bit may be reversed from this example. For example, a value of '0' for the bit may mean that the absolute value of the difference between the actual MPR value for CP-OFDM and the actual MPR value for DFT-S-OFDM is equal to or greater than a threshold, and a value of '1' for the bit may mean that the absolute value is less than the threshold. The meaning of the value of the bit may be reversed from this example.

[0135] The range of values ​​of P_CMAX to be reported may follow at least one of several options: -- Option 1: Mapping between PH values ​​and values ​​(ranges) of the measurement quantity in the existing specification (e.g., Figure 6); -- Option 2: Mapping / range / multiple values ​​between PH values ​​and values ​​(ranges) of the measurement quantity defined in a new specification; -- Option 3: Mapping / range / multiple values ​​configured by RRC; -- Option 4: Mapping / range / multiple values ​​indicated by MAC CE / DCI.

[0136] The range of values ​​of the reported MPR may follow at least one of the following options: -- Option 1: Mapping / range / multiple values ​​newly defined in the specification. For example, the range may be from 0 dB to 5 dB with a granularity of 0.5 dB. -- Option 2: Mapping / range / multiple values ​​configured by the RRC. For example, the range / granularity of values ​​may be configured by the RRC. -- Option 3: Mapping / range / multiple values ​​indicated by the MAC CE / DCI. For example, the range / granularity of values ​​may be indicated by the MAC CE / DCI.

[0137] The range of values ​​of the reported P_CMAX / MPR difference may follow at least one of the following options: -- Option 1: Mapping / range / multiple values ​​newly defined in the specification. For example, the range may be from 0 dB to 5 dB with a granularity of 0.5 dB. For example, the range may be from -5 dB to 5 dB with a granularity of 0.5 dB. -- Option 2: Mapping / range / multiple values ​​configured by the RRC. For example, the range / granularity of the values ​​may be configured by the RRC. -- Option 3: Mapping / range / multiple values ​​indicated by the MAC CE / DCI. For example, the range / granularity of the values ​​may be indicated by the MAC CE / DCI.

[0138] -Embodiment #1-2 Reporting of information regarding whether dynamic UL waveform switching is beneficial or not may follow at least one of the following options.

[0139] --Option 1: The information may be reported via UE capability information, where a pre-requisite feature for reporting may be dynamic waveform switching.

[0140] A feature group may be defined for reporting at least one of the following pieces of information: Information indicating whether the difference between the MPR (backoff) for CP-OFDM and the MPR (backoff) for DFT-S-OFDM is greater than a threshold; Information indicating, for each modulation scheme, whether the difference between the MPR (backoff) for CP-OFDM and the MPR (backoff) for DFT-S-OFDM is greater than a threshold; Information indicating, for each modulation scheme and RB allocation, whether the difference between the MPR (backoff) for CP-OFDM and the MPR (backoff) for DFT-S-OFDM is greater than a threshold.

[0141] --Option 2: The information may be reported via MAC CE on PUSCH. The reporting may be periodic / semi-persistent / aperiodic. P_CMAX in the following MAC CE example may be replaced with information (one of several options) about whether dynamic UL waveform switching in embodiment #1-1 is beneficial.

[0142] The report may follow some examples below.

[0143] --Example 1 The report may be based on a single entry PHR MAC CE.

[0144] As shown in the example of Figure 10, in a single-entry PHR MAC CE, the "R" field in octet 1 may be replaced with a specific field (e.g., an "X" field). For example, the "X" field may indicate whether the difference between the actual multiple MPR values ​​is greater than or equal to a threshold (option 4a).

[0145] --Example 2 The report may be based on multiple entry PHR MAC CE.

[0146] As shown in the example of Figure 11, one or more new octets may be added in a multiple-entry PHR MAC CE. The new octet may include N specific fields (e.g., "X_i" fields). For example, the "X_i" field may indicate whether the difference between the actual multiple MPR values ​​corresponding to the index i of the activated cell is greater than or equal to a threshold.

[0147] A multiple-entry PHR MAC CE may include one specific field. As shown in the example of Figure 12, the "R" field in the first octet may be replaced with a specific field (e.g., an "X" field). For example, the "X" field may indicate whether the difference between the actual multiple MPR values ​​for all activated cells is greater than or equal to a threshold.

[0148] --Example 3 The report may be based on an extended single-entry PHR MAC CE or an extended multiple-entry PHR MAC CE.

[0149] One or more "R" fields may be replaced with a specific field (e.g., an "X" field).

[0150] The MAC CE (octets 5, 6, ...) may include an "X_i" field for each beam (SSBRI or CRI). As shown in the example of Figure 13, the "X_i" field may replace the "R" field in the same octet as the SSBRI or CRI. For example, the "X_i" field for each beam may indicate whether the difference between the actual multiple MPR values ​​corresponding to that beam is greater than or equal to a threshold. By reporting the "X_i" field for each beam, the UE can determine / report beam-specific information, and the base station can use the beam-specific information for scheduling.

[0151] The MAC CE may include one "X" field. As shown in the example of Figure 14, the "R" field in the first octet may be replaced with the "X" field. For example, the "X" field may indicate whether the difference between the actual multiple MPR values ​​(for all beams reported by this MAC CE) is greater than or equal to a threshold.

[0152] --Example 4: The reporting may be based on a single-entry PHR MAC CE / multiple-entry PHR MAC CE. As in the example of Figure 15, the "R" field in octet 1 may be replaced with a specific field (e.g., an "X" field). For example, the "X" field may indicate whether an MPE (P-MPR) or an actual MPR is reported using the two most significant bits (MSBs) in octet 2. X=0 may mean that an MPE (P-MPR) is reported, and X=1 may mean that an actual MPR is reported. The meaning of the values ​​may be reversed from this example.

[0153] A table showing the mapping of the actual MPR may be defined in the specification, as in the example of Figure 16. If X=1 (the actual MPR is reported), the actual MPR may be reported using the 2 MSBs in octet 2 based on the table.

[0154] When X=1 (when the actual MPR is reported), the usage of the "P" field in octet 1 may follow one of several examples below. --- Example 4-1 P=0 may mean that the actual MPR is lower than ActualMPR_00 (e.g., 1 dB), and P=1 may mean that the actual MPR is equal to or greater than ActualMPR_00 (e.g., 1 dB). The meaning of the values ​​may be reversed from this example. --- Example 4-2 P=0 may mean that the actual MPR is for CP-OFDM, and P=1 may mean that the actual MPR is for DFT-S-OFDM. The meaning of the values ​​may be reversed from this example.

[0155] As in the example of Figure 17, the "P" and "R" fields in octet 1 may be replaced by a 2-bit "X" field. As in the example of Figure 18, the "X" field may indicate the usage of the 2 MSBs in octet 2 according to the following. The order of these values ​​may differ from this example: ---X=00 means that neither the actual MPR nor the MPE (P-MPR) is reported. ---X=01 means that the actual MPR is reported. ---X=10 means that the MPE (P-MPR) is reported. ---X=11 is reserved.

[0156] If X=01 (if actual MPR is reported), the usage of the "P" field in octet 1 may follow one of several examples below: If X=1 (if actual MPR is reported), the actual MPR may be reported using the 2 MSBs in octet 2 based on a table showing the mapping of the actual MPR.

[0157] As shown in the example of Fig. 19, RRC parameters for MPR reporting may be defined. The PHR configuration (PHR-Config) may include an MPR reporting configuration (mpr-Reporting-r18 / MPR-Report-Config-r18). The MPR-Report-Config-r18 may include a prohibition timer (mpr-Report-ProhibitTimer-r18) / threshold (mpr-Report-Threshold-r18).

[0158] --Example 5: The reporting may be based on a single-entry PHR MAC CE / multiple-entry PHR MAC CE. As described in Option 1 of Embodiment #1-1, a new octet may be added to report at least one piece of information for each category. The information may be at least one of PH, P_CMAX, and MPE. As described in Option 1 of Embodiment #1-1, the category may be for each waveform, for each combination of waveform and modulation scheme, or for each combination of waveform, modulation scheme, and RB allocation. As in the example of Figure 20, octet 2 may indicate P_CMAX for CP-OFDM, and the added octet 3 may indicate P_CMAX for DFT-S-OFDM. The order of these values ​​may be different from this example.

[0159] --Variation of Example 5 The reporting may be based on a single-entry PHR MAC CE / multiple-entry PHR MAC CE. As described in Option 1 of Embodiment #1-1, a new octet may be added to report at least one piece of information for each category. The information may be at least one of PH, P_CMAX, and MPE. As described in Option 1 of Embodiment #1-1, the category may be for each waveform, for each combination of waveform and modulation scheme, or for each combination of waveform, modulation scheme, and RB allocation. As in the example of Figure 21, octet 2 may indicate P_CMAX for an RRC-configured waveform (e.g., CP-OFDM), and the added octet 3 may indicate P_CMAX for a waveform (e.g., DFT-S-OFDM) indicated (dynamically / by DCI). The order of these values ​​may be different from this example.

[0160] The "R" field in octet 1 may be used to report whether a new (additional) octet (octet 3) is present. For example, if R=0, no new octet is present, and if R=1, a new octet may be present. The meaning of the values ​​may be reversed from this example.

[0161] Information that is not reported per category may follow the assumptions of at least one of the following options: --Option 2-1-1: The information is the same across multiple categories. For example, if P_CMAX is reported per waveform, PH / MPE may be common to multiple waveforms. --Option 2-1-2: The information is implicitly determined / reported. For example, if P_CMAX is reported per waveform, the PH for CP-OFDM may be reported in octet 1, and the PH for DFT-S-OFDM may be calculated. For example, (PH for DFT-S-OFDM) = (PH for CP-OFDM) + (P_CMAX for DFT-S-OFDM) - (P_CMAX for CP-OFDM).

[0162] The resource configuration method for the PUSCH with that MAC CE may follow at least one of the following options.

[0163] --Option 2-2-1 Resources for PUSCH with MAC CE may be allocated by scheduling DCI.

[0164] --Option 2-2-2 A resource pool may be configured by the RRC. The resource pool may be a set of downlink RSs corresponding to a certain cell. The method of determining a resource from the resource pool may follow at least one of the following options: --Option 2-2-2-1 The NW configures / indicates one resource in the resource pool. --Option 2-2-2-2 The UE selects one resource in the resource pool. In this case, the NW may assume that a MAC CE is multiplexed onto a PUSCH in the configured resource pool.

[0165] --Option 3: The information may be reported via UCI on PUCCH / PUSCH. The reporting may be periodic / semi-persistent / aperiodic.

[0166] According to this embodiment, the UE can be instructed on the appropriate UL waveform.

[0167] <Supplementary Note> At least one operation of the above-described embodiment may be applied only to UEs that have reported or support a specific UE capability.

[0168] The specific UE capability may indicate at least one of the following: Support for embodiment 1. Support for embodiment 1 for a certain band. Support for embodiment 1 for a certain band combination. Support for embodiment 1 for a certain band within a certain band combination. Support for embodiment 1 for a certain CC in a certain band within a certain band combination.

[0169] Furthermore, the specific UE capability may be a capability that is applied across all frequencies (commonly regardless of frequency), or may be a capability for each frequency (e.g., cell, band, BWP), or may be a capability for each frequency range (e.g., Frequency Range 1 (FR1), FR2, FR3, FR4, FR5, FR2-1, FR2-2), or may be a capability for each subcarrier spacing (SubCarrier Spacing (SCS)).

[0170] Furthermore, the specific UE capability may be a capability that is applied to all duplexing methods (commonly regardless of the duplexing method), or may be a capability for each duplexing method (e.g., Time Division Duplex (TDD) or Frequency Division Duplex (FDD)).

[0171] Furthermore, at least one operation of the above-described embodiment may be applied when the UE is configured with specific information related to the above-described embodiment by higher layer signaling. For example, the specific information may be information indicating that at least one operation of the above-described embodiment is enabled, any RRC parameter for a specific release (e.g., Rel. 18), etc.

[0172] If the UE does not support at least one operation of the specific UE capability or is not configured with the specific information, the UE may apply the operation of, for example, Rel. 15 / 16 / 17.

[0173] (Supplementary Notes) The following inventions are supplementary notes regarding one embodiment of the present disclosure. [Supplementary Note 1] A terminal having: a transmitter that transmits a report based on an uplink transmission waveform; and a controller that controls the uplink transmission based on the report. [Supplementary Note 2] The terminal according to Supplementary Note 1, wherein the report relates to a set maximum output power or a maximum power reduction. [Supplementary Note 3] The terminal according to Supplementary Note 1 or Supplementary Note 2, wherein the report is associated with at least one of the waveform, a modulation scheme, and a resource block allocation. [Supplementary Note 4] The terminal according to any of Supplementary Notes 1 to 3, wherein the transmitter transmits the report via any of capability information, a medium access control (MAC) control element (CE), and uplink control information.

[0174] (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.

[0175] 22 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication 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).

[0176] 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.

[0177] 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.

[0178] 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))).

[0179] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The locations and numbers of the cells and user terminals 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0180] 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).

[0181] 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.

[0182] 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.

[0183] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

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.

[0194] 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.

The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0196] 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.

[0197] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted.

[0238] The transmitter may transmit the report via any of capability information, a medium access control (MAC) control element (CE), and uplink control information.

[0239] (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.

[0241] 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 25 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.

[0242] 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.

[0243] 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.

[0244] 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.

[0245] 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.

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.

[0247] 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.

[0248] 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.

[0249] 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.

[0250] 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).

[0251] 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.

[0252] 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.

[0253] (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.

[0254] 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.

[0255] 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.

[0256] 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.

[0257] 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.

[0258] 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.

[0259] 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.

[0260] 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.

[0261] 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.

[0262] 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.

[0263] 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.

[0264] 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.

[0265] 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.

[0266] 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.

[0267] 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 group / set / pair of PRB / RB, etc.

[0268] 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.

[0269] 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.

[0270] 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.

[0271] 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."

[0272] 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.

[0273] 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.
