In other words, a terminal device 1 that does not support the BWP switching function may recognize that it will receive the PDSCH without switching the active downlink BWP based on detecting DCI format 1_1 that is used for scheduling the PDSCH and includes a BWP field. Here, if the terminal device 1 supports the BWP switching function, it may report that "the terminal device 1 supports the BWP switching function" in the RRC layer capability information reporting procedure.

[0165] When DCI format 1_1 includes a carrier indicator field, the carrier indicator field may be used to indicate a downlink component carrier on which a PDSCH is arranged. When DCI format 1_1 does not include a carrier indicator field, the downlink component carrier on which a PDSCH is arranged may be the same as a downlink component carrier on which a PDCCH including DCI format 1_1 used for scheduling the PDSCH is arranged. When the number of downlink component carriers configured in a terminal device 1 in a certain serving cell group is two or more (when downlink carrier aggregation is operated in a certain serving cell group), the number of bits of the carrier indicator field included in DCI format 1_1 used for scheduling a PDSCH arranged in the certain serving cell group may be one bit or more (for example, three bits). When the number of downlink component carriers configured for a terminal device 1 in a certain serving cell group is 1 (when downlink carrier aggregation is not operated in a certain serving cell group), the number of bits in the carrier indicator field included in DCI format 1_1 used for scheduling the PDSCH placed in the certain serving cell group may be 0 bits (or the carrier indicator field may not be included in DCI format 1_1 used for scheduling the PDSCH placed in the certain serving cell group).

[0166] The PDSCH may be transmitted to transmit a transport block. The PDSCH may be used to transmit a transport block delivered by the DL-SCH. The PDSCH may be used to transmit a transport block. A transport block may be allocated to the PDSCH. A transport block corresponding to the DL-SCH may be allocated to the PDSCH. The base station device 3 may transmit the PDSCH. The terminal device 1 may receive the PDSCH.

[0167] The downlink physical signal may correspond to a set of resource elements. The downlink physical signal may not carry information generated in a higher layer. The downlink physical signal may be a physical signal used in a downlink component carrier. The downlink physical signal may be transmitted by a base station device 3. The downlink physical signal may be transmitted by a terminal device 1. In a wireless communication system according to one aspect of this embodiment, at least some or all of the following downlink physical signals may be used. ·Synchronization signal (SS) ·DL DMRS(DownLink DeModulation Reference Signal) ·CSI-RS(Channel State Information-Reference Signal) ·DL PTRS(DownLink Phase Tracking Reference Signal)

[0168] The synchronization signal may be used by the terminal device 1 to synchronize one or both of the frequency domain and the time domain of the downlink. The synchronization signal is a general term for a PSS (Primary Synchronization Signal) and an SSS (Secondary Synchronization Signal).

[0169] FIG. 7 is a diagram showing an example of the configuration of an SS / PBCH block according to one aspect of this embodiment. In FIG. 7, the horizontal axis is the time axis (OFDM symbol index l sym), where the vertical axis represents the frequency domain. Block 700 represents a set of resource elements for the PSS. Block 720 represents a set of resource elements for the SSS. Four blocks (blocks 710, 711, 712, and 713) represent sets of resource elements for the PBCH and DMRS for the PBCH (DMRS related to the PBCH, DMRS included in the PBCH, and DMRS corresponding to the PBCH).

[0170] As shown in FIG. 7, the SS / PBCH block includes a PSS, SSS, and PBCH. The SS / PBCH block includes four consecutive OFDM symbols. The SS / PBCH block includes 240 subcarriers. The PSS is the first OFDM symbol. The SSS is allocated to the 57th to 183rd subcarriers in the third OFDM symbol. The 1st to 56th subcarriers in the first OFDM symbol may be set to zero. The 184th to 240th subcarriers in the first OFDM symbol may be set to zero. The 49th to 56th subcarriers in the third OFDM symbol may be set to zero. The 184th to 192nd subcarriers in the third OFDM symbol may be set to zero. The PBCH is allocated to the 1st to 240th subcarriers in the second OFDM symbol, which are subcarriers where the DMRS for the PBCH is not allocated. The PBCH is allocated to the 1st to 48th subcarriers in the third OFDM symbol, which are subcarriers where the DMRS for the PBCH is not allocated. The PBCH is allocated to the 193rd to 240th subcarriers of the third OFDM symbol, which are subcarriers where no DMRS for the PBCH is allocated, and the PBCH is allocated to the 1st to 240th subcarriers of the fourth OFDM symbol, which are subcarriers where no DMRS for the PBCH is allocated.

[0171] The antenna ports for the PSS, SSS, PBCH, and DMRS for the PBCH may be the same.

[0172] The PBCH on which the PBCH symbol is transmitted at a certain antenna port may be estimated by the DMRS for the PBCH that is placed in the slot to which the PBCH is mapped and is included in the SS / PBCH block to which the PBCH belongs.

[0173] DL DMRS is a general term for DMRS for PBCH, DMRS for PDSCH, and DMRS for PDCCH.

[0174] The set of antenna ports for DMRSs for a PDSCH (DMRSs associated with a PDSCH, DMRSs included in a PDSCH, and DMRSs corresponding to a PDSCH) may be determined based on the set of antenna ports for the PDSCH, i.e., the set of antenna ports for DMRSs for a PDSCH may be the same as the set of antenna ports for the PDSCH.

[0175] The transmission of the PDSCH and the transmission of the DMRS for the PDSCH may be indicated (or scheduled) by one DCI format. The PDSCH and the DMRS for the PDSCH may be collectively referred to as the PDSCH. Transmitting the PDSCH may also mean transmitting the PDSCH and the DMRS for the PDSCH.

[0176] A propagation path of a PDSCH may be estimated from a DMRS for the PDSCH. If a set of resource elements carrying a certain PDSCH symbol and a set of resource elements carrying a DMRS symbol for the PDSCH are included in the same precoding resource group (PRG), the PDSCH carrying the PDSCH symbol for a certain antenna port may be estimated by the DMRS for the PDSCH.

[0177] The antenna port of the DMRS for the PDCCH (DMRS related to the PDCCH, DMRS included in the PDCCH, DMRS corresponding to the PDCCH) may be the same as the antenna port for the PDCCH.

[0178] The PDCCH may be estimated from the DMRS for the PDCCH. The propagation path of a PDCCH may be estimated from the DMRS for the PDCCH. If the same precoder is applied (or assumed to be applied) to a set of resource elements on which a certain PDCCH symbol is transmitted and a set of resource elements on which a DMRS symbol for the PDCCH is transmitted, the PDCCH on which a certain antenna port transmits a PDCCH symbol may be estimated by the DMRS for the PDCCH.

In other words, the dedicated RRC parameters are higher layer parameters that can provide unique settings for each of the terminal devices 1-A, 1-B, and 1-C.

[0187] The BCCH of the logical channel is mapped to the BCH or DL-SCH of the transport layer. For example, a transport block containing MIB information is delivered to the BCH of the transport layer. A transport block containing system information other than MIB is delivered to the DL-SCH of the transport layer. The CCCH is mapped to the DL-SCH or UL-SCH. In other words, a transport block mapped to the CCCH is delivered to the DL-SCH or UL-SCH. The DCCH is mapped to the DL-SCH or UL-SCH.

The RRC message may also include a message corresponding to a DCCH. An RRC message including a message corresponding to a DCCH is also referred to as a dedicated RRC message.

[0189] The upper layer parameters (parameters of the upper layer) are RRC parameters or parameters included in a Medium Access Control Element (MAC CE). Upper layer parameters are a general term for the parameters included in MIB, system information, CCCH-compatible messages, DCCH-compatible messages, and MAC CE.

[0228] In uplink communication, the terminal device 1 detects an uplink DCI format. The detected DCI format is used at least for PUSCH resource allocation. The detected uplink DCI format is also called an uplink grant. The terminal device 1 transmits the PUSCH.

[0229] In configured scheduling (configured grant), an uplink grant for scheduling a PUSCH is configured for each transmission period of the PUSCH. When a PUSCH is scheduled by an uplink DCI format, some or all of the information indicated by the uplink DCI format may be indicated by the uplink grant configured in the case of configured scheduling.

[0231] Repeated transmission may be applied to a PUSCH scheduled by DCI. Also, repeated transmission may be applied to a PUSCH scheduled by a configured uplink grant. The PUSCH repetition type may be either PUSCH repetition type A or PUSCH repetition type B. The PUSCH repetition type may be configured by a higher layer parameter. The PUSCH repetition type may be based on the DCI format. For example, a first PUSCH repetition type for a PUSCH scheduled by DCI format 0_1 ​​may be different from a second PUSCH repetition type for a PUSCH scheduled by DCI format 0_2.

[0232] The number of repetitions for PUSCH repeat transmission may be configured by a higher layer parameter. For example, the higher layer parameter numberOfRepetitions may be a parameter including the number of repetitions for PUSCH repeat transmission. In PUSCH repeat transmission corresponding to PUSCH repetition type A, the number of repetitions for the PUSCH repeat transmission may be determined by the value of the higher layer parameter numberOfRepetitions. In PUSCH repetition type A, the number of repetitions for a PUSCH whose transmission is indicated by a DCI format including a CRC scrambled by C-RNTI and either MCS-C-RNTI or CS-RNTI may be equal to numberOfRepetitions if the numberOfRepetitions is present in the resource allocation table. When one PUSCH-TimeDomainResourceAllocation includes one or more PUSCH-Allocations, the higher layer parameter numberOfRepetitions may be configured for each PUSCH-Allocation. Furthermore, the PUSCH-TimeDomainResourceAllocation may be referred to as a resource allocation table.

[0233] The higher layer parameter pusch-AggregationFactor may be a parameter indicating the number of repetitions for PUSCH repeat transmission. In PUSCH repeat transmission corresponding to PUSCH repetition type A, the number of repetitions for the PUSCH repeat transmission may be determined by the value of the higher layer parameter pusch-AggregationFactor.

[0236] The upper layer parameters frequencyHopping, frequencyHoppingDCI-0-1, and frequencyHoppingDCI-0-2 are The parameter may indicate a frequency hopping scheme for the USCH. For example, a frequency hopping scheme corresponding to the frequency hopping for the PUSCH may be configured by frequencyHoppingDCI-0-2 in PUSCH-Config. Also, a frequency hopping scheme corresponding to the frequency hopping for the PUSCH may be configured by frequencyHopping in PUSCH-Config. Also, a frequency hopping scheme corresponding to the frequency hopping for PUSCH transmission configured by frequencyHopping in configuredGrantConfig may be configured. The frequency hopping scheme may be any of intra-slot frequency hopping, inter-slot frequency hopping, inter-repetition frequency hopping, and inter-bundle frequency hopping. Also, a frequency hopping interval corresponding to intra-slot frequency hopping may be one slot or less. A frequency hopping interval corresponding to inter-slot frequency hopping may be one slot. A frequency hopping interval corresponding to inter-repetition frequency hopping may be based on nominal repetition. A frequency hopping interval corresponding to inter-bundle frequency hopping may be one or more slots. A bundle may be a time unit consisting of multiple slots. A bundle may be the number of slots corresponding to the frequency hopping interval.

[0237] For example, if a first higher layer parameter indicating a frequency hopping scheme for a PUSCH indicates inter-slot frequency hopping and a bundle is provided by a second higher layer parameter, inter-bundle frequency hopping may be applied to the PUSCH. For example, if the higher layer parameter indicating a frequency hopping scheme for a PUSCH indicates inter-bundle frequency hopping, inter-bundle frequency hopping may be applied to the PUSCH.

[0238] For example, the bundle may be provided by a higher layer parameter. For example, if the higher layer parameter indicates N, a bundle of N slots may be provided for the PUSCH to which inter-bundle frequency hopping is applied. N may be an integer greater than 1. For example, if the higher layer parameter includes one value, the one value may be provided for one or both of the PUSCH to which inter-bundle frequency hopping is applied and the PUCCH. The one value may be an integer greater than 1. The one value may also be the window length of the configured time-domain window.

[0239] Whether to perform frequency hopping for a PUSCH whose transmission is instructed by the DCI format may be determined based at least on a value of a frequency hopping flag field included in the DCI format. Whether to perform frequency hopping for a PUSCH whose transmission is instructed by the random access response grant may be determined based at least on a value of a frequency hopping flag field included in the random access response grant. For example, frequency hopping for the PUSCH may be performed based at least on the value of the frequency hopping flag field being 1.

[0240] Intra-slot frequency hopping may be applied to PUSCH transmission in one or more slots. For example, intra-slot frequency hopping may be applied to PUSCH repeated transmission. For a PUSCH to which intra-slot frequency hopping is applied, the resource block arrangement may be switched for one or more OFDM symbols. For example, for a PUSCH to which intra-slot frequency hopping is applied, the resource block arrangement may be switched for one or more OFDM symbols in the first hop or the second hop. Also, when intra-slot frequency hopping is performed for the PUSCH, the first hop and the second hop may be switched every one or more OFDM symbols. The difference between the location of the first resource block of the first hop and the location of the first resource block of the second hop is RB offset RB offset may be configured by a higher layer parameter. The one or more OFDM symbols may be within one slot. The one or more OFDM symbols may be half the number of OFDM symbols for the PUSCH in one slot. Intra-slot frequency hopping may be applied to the PUSCH corresponding to PUSCH repetition type A.

[0241] Inter-slot frequency hopping may be applied to PUSCH transmission in multiple slots. For PUSCH to which inter-slot frequency hopping is applied, the resource block arrangement may be switched for each slot. For example, inter-slot frequency hopping may be applied to PUSCH repeated transmission. Also, when inter-slot frequency hopping is performed for PUSCH, the resource block arrangement may be switched between the first hop and the second hop for each slot. For example, in a certain slot, slot index n μ s,f If n is an even number, the PUSCH transmission in the slot may correspond to the first hop. For example, in a slot, slot index n μ s,f If ∑ i = 1 , ∑ j = 1 , ∑ j = 2 ...

[0242] Inter-repetition frequency hopping may be applied to a PUSCH corresponding to PUSCH repetition type B. For a PUSCH to which inter-repetition frequency hopping is applied, the first hop and the second hop may be switched based on the nominal repetition.

[0243] Inter-bundle frequency hopping may be applied to PUSCH transmission in multiple slots. For example, inter-bundle frequency hopping may be applied to PUSCH repetition transmission. For PUSCH to which inter-bundle frequency hopping is applied, resource block allocation may be switched for each bundle. Furthermore, when inter-bundle frequency hopping is performed for PUSCH, resource block allocation may be switched between the first hop and the second hop for each bundle. A bundle may be one or multiple slots. For example, a bundle may be determined by a higher layer parameter. For example, a bundle may be determined based on the number of repetitions. For example, a bundle may be composed of consecutive UL slots. For example, a bundle may be composed of a special slot and an UL slot. Inter-bundle frequency hopping may be applied to PUSCHs corresponding to either PUSCH repetition type A or PUSCH repetition type B.

[0244] The UL slot may be a slot consisting of UL symbols. The special slot may be a slot consisting of UL symbols, flexible symbols, and DL symbols. The DL slot may be a slot consisting of DL symbols.

[0245] The UL symbol may be an OFDM symbol configured or indicated for uplink in time division duplex. The UL symbol may be an OFDM symbol configured or indicated for PUSCH, PUCCH, PRACH, or SRS. The UL symbol may be configured by the higher layer parameter tdd-UL-DL-ConfigurationCommon. The UL symbol may be configured by the higher layer parameter tdd-UL-DL-ConfigurationDedicated. The UL slot may be configured by the higher layer parameter tdd-UL-DL-ConfigurationCommon. The UL slot may be configured by the higher layer parameter tdd-UL-DL-ConfigurationDedicated. May be set by tdd-UL-DL-ConfigurationDedicated.

[0246] The DL symbol may be an OFDM symbol configured or indicated for downlink in time division duplex. The DL symbol may be an OFDM symbol configured or indicated for PDSCH or PDCCH. The DL symbol may be configured by the higher layer parameter tdd-UL-DL-ConfigurationCommon. The DL symbol may be configured by the higher layer parameter tdd-UL-DL-ConfigurationDedicated. The DL slot may be configured by the higher layer parameter tdd-UL-DL-ConfigurationCommon. The DL slot may be configured by the higher layer parameter tdd-UL-DL-ConfigurationDedicated.

[0247] A flexible symbol may be an OFDM symbol within a period that is not configured or indicated as an UL symbol or DL ​​symbol. The period may be a period given by the higher layer parameter dl-UL-TransmissionPeriodicity. The flexible symbol may be an OFDM symbol configured or indicated for a PDSCH, PDCCH, PUSCH, PUCCH, or PRACH.

[0248] The upper layer parameter tdd-UL-DL-ConfigurationCommon may be a parameter for setting a UL slot, a DL slot, or a special slot for each of one or more slots. The upper layer parameter tdd-UL-DL-ConfigurationDedicated may be a parameter for setting a UL symbol, a DL symbol, or a flexible symbol for each of the one or more slots. The tdd-UL-DL-ConfigurationCommon may be a common upper layer parameter. The tdd-UL-DL-ConfigurationDedicated may be a dedicated upper layer parameter.

[0249] A time domain window may indicate a time domain period. For example, the time domain window may be used for DMRS bundling. A terminal device 1 that performs DMRS bundling may be able to perform channel estimation using DMRSs included in two or more PUSCHs in a period based on the time domain window. A terminal device 1 that performs DMRS bundling may be expected to maintain phase continuity and / or power consistency between two PUSCHs in a period based on the time domain window. DMRS bundling may be referred to as joint channel estimation.

[0250] The time domain window may be a general term for a configured time domain window and an actual time domain window.

[0251] Whether DMRS bundling is applied may be configured by a higher layer parameter. The application of DMRS bundling may mean that one or both of the configured time domain window and the actual time domain window are enabled. For example, the application of DMRS bundling may mean that the higher layer parameter PUSCH-DMRS-Bundling is enabled. For example, the non-application of DMRS bundling may mean that the higher layer parameter PUSCH-DMRS-Bundling is enabled. It may not be necessary to do so.

[0252] The time domain window to be set may consist of one or more consecutive slots. The time domain window to be set may be configured by one or more higher layer parameters. For example, the one or more higher layer parameters may include one or more parameters that can enable the time domain window to be set. For example, the one or more higher layer parameters may include one or more parameters that indicate the length of the time domain window to be set. The length of the time domain window to be set may be referred to as a window length. The time domain window to be set may consist of slots corresponding to the window length. The start position of the time domain window to be set may be determined based on the first PUSCH of the PUSCH repetition transmission. For example, the start position of the time domain window to be set may be the first slot of the PUSCH repetition transmission. For example, the start position of the time domain window to be set may be the first slot in which a PUSCH to which PUSCH repetition type A is applied is transmitted. For example, the start position of the time domain window to be set may be the slot corresponding to the first transmission opportunity for a PUSCH to which PUSCH repetition type A is applied.

[0253] The window length may be provided by a higher layer parameter. The window length may be determined based on a bundle. For example, the window length may be a bundle. For example, the window length may be used as a bundle for inter-bundle frequency hopping. For example, either the first hop or the second hop may correspond to multiple PUSCH transmissions in the configured time domain window. The configured time domain window and a portion of the window length, or both, may be used for precoding. For example, the same precoding may be applied to multiple PUSCH transmissions in the configured time domain window. The configured time domain window and a portion of the window length, or both, may be used for terminal adjustment of the terminal device 1. For example, a frequency synchronization error may not be corrected in the configured time domain window. For example, a time timing synchronization error may not be corrected in the configured time domain window. For example, an adjustment related to antenna virtualization may not be performed in the configured time domain window. For example, an analog circuit controlled by a digital signal may not be adjusted in the configured time domain window. For example, a high-frequency circuit may not be adjusted in the configured time domain window. The adjustment of the high frequency circuit may be some or all of the following: changing the operating point of the power amplifier, changing the gain of the power amplifier, phase synchronization of the oscillator, phase adjustment of the two carrier waves, phase adjustment of the phase shifter, and stopping the power supply to the high frequency circuit.

[0254] The window length may have a maximum period determined. For example, the maximum period may be reported by the terminal device 1 to the base station device 3. For example, the maximum period may be the number of repetitions.

[0255] One or more window lengths may be configured in PUSCH-Config. Also, one or more window lengths may be configured in PUSCH-ConfigCommon. For example, one of the one or more window lengths may be determined based on a DCI format. For example, one of the one or more window lengths may be determined based on a time domain resource allocation field included in DCI.

[0256] In Frequency Division Duplex, two or more configured time domain windows may be consecutive. For example, the last slot in a first configured time domain window may be consecutive with the last slot in a second configured time domain window. It may be consecutive with the first slot in (c).

[0257] In time division duplexing, two or more configured time domain windows may be contiguous. Also, in time division duplexing, two or more configured time domain windows may not be contiguous. For example, the start position of the configured time domain window may be determined based on at least one or both of the tdd-UL-DL-ConfigurationCommon and the tdd-UL-DL-ConfigurationDedicated. For example, the start position of the configured time domain window may not include a DL slot.

[0258] The first configured time domain window of the one or more configured time domain windows may end just before a DL slot, and the configured time domain windows other than the first configured time domain window of the one or more configured time domain windows may be aligned with the period given by dl-UL-TransmissionPeriodicity.

[0259] The configured time domain window may end based on a certain slot index. For example, n μ s,fIf n is the first value, μ s,f The set time domain window may end at the end of the slot corresponding to n. The set time domain window may be applied to the PUSCH transmitted in the slot. The first value may be 0. The first value may be set by a higher layer parameter. The first value may be determined based on a certain period. For example, the certain period may be used for processing performed every certain period. The certain period may be an integer multiple of the window length of the set time domain window. The first value may be determined by the certain period and an offset. Also, n μ s,f If n is the second value, μ s,f The time domain window may end at the end of the slot corresponding to . The difference between the first value and the second value may be the certain period.

[0260] The last configured time domain window of the one or more configured time domain windows may end in a slot corresponding to the last PUSCH in the PUSCH repeated transmission.

[0261] One or more actual time domain windows may be determined in the set time domain window. The multiple actual time domain windows may not be contiguous with each other. The terminal device 1 may be expected to maintain phase continuity and power consistency in the actual time domain window. The actual time domain window may consist of one or more slots. The actual time domain window may also consist of one or more OFDM symbols.

[0262] The actual time domain window may be determined based on events occurring within the configured time domain window. The actual time domain window may be determined based on slots or OFDM symbols corresponding to events in the configured time domain window. The actual time domain window may not include slots or OFDM symbols corresponding to events in the configured time domain window. For example, the events may include reception of a downlink physical channel and some or all of transmission of a high priority channel, slot format indication, frequency hopping, and cancellation indication.

[0263] For example, the slot or OFDM symbol corresponding to the event may be a slot or OFDM symbol in which PUSCH repeat transmission is canceled. For example, a slot corresponding to an event may be a DL slot. For example, a slot or OFDM symbol corresponding to an event may be a slot or OFDM symbol including a DL reception opportunity. For example, a slot or OFDM symbol corresponding to an event may be a slot or OFDM symbol in which a high-priority channel is transmitted. For example, a slot corresponding to an event may be a slot indicated as a DL slot or a special slot by the slot format instruction. For example, an OFDM symbol corresponding to an event may be an OFDM symbol indicated as a DL symbol or a flexible symbol by the slot format instruction. For example, a slot corresponding to an event may be the n-th slot associated with the second hop when the n-1-th slot is associated with the first hop. For example, a slot corresponding to an event may be the n-th slot associated with the first hop when the n-1-th slot is associated with the second hop. For example, an OFDM symbol corresponding to an event may be the n-th OFDM symbol associated with the second hop when the n-1-th OFDM symbol is associated with the first hop. For example, the OFDM symbol corresponding to the event may be the nth OFDM symbol associated with the first hop, where the n-1th slot is associated with the second hop.

[0264] The actual time domain window may include OFDM symbols in which the PUSCH is not transmitted. For example, the actual time domain window may include 13 consecutive OFDM symbols in which the terminal device 1 does not transmit an uplink physical channel and an uplink physical signal.

[0265] The terminal device 1 may maintain phase continuity and transmit power consistency within the actual time domain window based on requirements for phase continuity and transmit power consistency. For example, the terminal device 1 may be expected to maintain phase continuity and transmit power consistency within the actual time domain window. For example, in the actual time domain window, an uplink physical channel and two OFDM symbols on which an uplink physical signal is transmitted may correspond to the same antenna port. For example, the terminal device 1 may determine whether to transmit a first channel on which a symbol at an antenna port is transmitted so that it can be estimated from a second channel on which other symbols at the antenna port are transmitted, based on whether the first channel and the second channel are included in an actual time domain window. For example, if the first channel and the second channel are included in the actual time domain window, the terminal device 1 may transmit a first channel on which a symbol at the antenna port is transmitted so that it can be estimated from the second channel on which other symbols at the antenna port are transmitted. Furthermore, when the first channel and the second channel are not included in the certain actual time domain window, the terminal device 1 may not transmit the first channel on which a symbol at the certain antenna port is transmitted so that the first channel can be estimated from the second channel on which other symbols at the certain antenna port are transmitted. Here, the first channel may be different from the second channel. Alternatively, the first channel may be the same as the second channel. Furthermore, the first channel may be a repetition of a third channel, and the second channel may be another repetition of the third channel. For example, the terminal device 1 may not change parameters related to precoding for the PUCCH and / or PUSCH in the actual time domain window. For example, the parameters related to precoding may be a precoding matrix for spatial multiplexing. Furthermore, the parameters related to precoding may be an upper layer parameter txConfig.Furthermore, the parameter related to the precoding may be a Transmitted Precoding Matrix Indicator (TPMI). The TPMI may be provided by a DCI format. Furthermore, the parameter related to the precoding may be an SRS Resource Indicator (SRI). Furthermore, the terminal device 1 may apply one precoding to a repetition of a PUSCH in the actual time domain window. For example, power control may be performed for the first PUSCH in the actual time domain window. Furthermore, power control may not be performed for one or more PUSCHs other than the first PUSCH in the actual time domain window. For example, a value in the TPC command field may be applied for the first PUSCH in the actual time domain window. Furthermore, a value in the TPC command field may not be applied for one or more PUSCHs other than the first PUSCH in the actual time domain window. The TPC command field for PUSCHs may be included in DCI format 0_0, DCI format 0_1, DCI format 0_2, DCI format 2_2, DCI format 2_3, and part or all of the random access response grant. Furthermore, the terminal device 1 may not perform frequency hopping on the repetition of the PUSCH in the actual time domain window. Not performing frequency hopping may mean that the repetition of the PUCCH in the actual time domain window is arranged in at least one of the first hop or the second hop. Furthermore, the terminal device 1 may not perform beam switching on the PUSCH in the actual time domain window. Furthermore, the terminal device 1 may not change the setting of the modulation scheme for PUSCH transmission and the modulation order in the actual time domain window. Furthermore, the terminal device 1 may not change the index of the first resource block for PUSCH transmission and the number of resource blocks in the actual time domain window. Furthermore, one or more PUSCHs in the actual time domain window may correspond to the same time domain resource allocation.Furthermore, the same precoding may be applied to one or more PUSCHs in the actual time domain window. Furthermore, the same transmission power control may be applied to one or more PUSCHs in the actual time domain window. Furthermore, one or more PUSCHs in the actual time domain window may be arranged in at least the same resource block. Furthermore, between two non-consecutive PUSCHs in the actual time domain window, the terminal device 1 may transmit a baseband signal with an amplitude of 0.

[0266] Uplink power control may determine the power for the PUSCH, PUCCH, SRS, and PRACH.

[0267] The terminal device 1 determines the PUSCH transmission power P PUSCH,b,f,c (i,j,q d , l). The transmit power control unit may determine the transmit power for the PUSCH. For example, the transmit power control unit may determine the transmit power P PUSCH,b,f,c (i,j,q d , l) may be determined. b may be an index for identifying an active BWP or an active uplink BWP among one or more BWPs. f may be an index for identifying one carrier among one or more carriers. c may be an index for identifying one serving cell among one or more serving cells. j may be an index for identifying one parameter set among one or more parameter sets configured by higher layer parameters. For example, the PUSCH transmission power P PUSCH,b,f,c (i,j,q d , l), the parameter set identified by index j may be used. l may be a value for specifying the power control adjustment state. For example, when l is 0, the terminal device 1 may maintain one power control state. For example, when l is 1, the terminal device 1 may maintain two power control states. q dmay be an index for identifying one reference signal among one or more reference signals. For example, the reference signal may be a physical signal used for channel measurement. For example, the reference signal may be an SS / PBCH block or a CSI-RS.

[0268] When the terminal device 1 transmits a PUSCH in an active BWP b of a carrier f of a serving cell c, the transmission power P PUSCH,b,f,c (i,j,q d , l) may be determined based at least on the parameter set identified by j and the power control adjustment state identified by l. P PUSCH,b,f,c (i,j,q d , l) may be determined based on Equation 1

[0269] PUSCH transmission opportunity i is the slot index n μ s,f PUSCH transmission opportunity i may be defined by: PUSCH transmission opportunity i may be a slot. For example, PUSCH transmission opportunity i may be a time timing at which transmission power control is performed. For example, if PUSCH transmission opportunity i is the first slot, transmission power control may be performed in the first slot. PUSCH transmission opportunity i for PUSCH repetition type B may be a nominal repetition.

[0270] The PUSCH transmission opportunity i may be the same as the length of the configured time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be the same as the length of the configured time domain window. The PUSCH transmission opportunity i may be the same as the window length configured by a higher layer parameter. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be the same as the window length. The PUSCH transmission opportunity i may be the same as the length of the actual time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be the same as the length of the actual time domain window. For example, the terminal device 1 may recognize / define the length of the configured time domain window as the PUSCH transmission opportunity i. For example, the terminal device 1 may recognize / define the length of the actual time domain window as the PUSCH transmission opportunity i.

[0271] If j is 0, P PUSCH,b,f,c (i,j,q d , l) may be the transmit power for the PUSCH scheduled by the random access response grant. If j is 1, P PUSCH,b,f,c (i,j,q d , l) may be the transmit power for the PUSCH scheduled by the configured uplink grant. If j is greater than 1, P PUSCH,b,f,c (i,j,q d , l) may be the transmit power for the PUSCH scheduled by the DCI.

[0276] PL b,f,c (q d ) may be the propagation path loss. For example, PL b,f,c (q d ) is q d The propagation path loss may be a value estimated based on a reference signal specified by the following equation. The propagation path loss may be a downlink propagation path loss. Also, the propagation path loss may be an uplink propagation path loss.

[0277] Δ TF,b,f,c (i) may be a transport format. TF,b,f,c (i) may be a power variation based on the number of information bits per resource element. TF,b,f,c (i) may be determined based on Equation 3. For example, if the number of transmission layers is greater than 1, Δ TF,b,f,c (i) may be 0. For example, when DMRS bundling is applied, Δ TF,b,f,c (i) may be 0.

number

[0278] The BPRE may be the number of information bits in one resource element among one or more resource elements. For example, the BPRE may be the number of information bits per resource element. Here, the information bits may include a transport block, a CRC sequence attached to the transport block, and part or all of a CRC sequence attached to each of one or more code blocks obtained by dividing the transport block. For example, for a PUSCH used to transmit a transport block, the BPRE may be determined based on the size of the transport block and the number of resource elements for the PUSCH. The BPRE may be determined based on Equation 4. For example, when a PUSCH is used to transmit a transport block delivered by an UL-SCH, the BPRE may be determined based on Equation 4.

When DM is applied, i'0 may be determined so that the first slot of one or more slots constituting the set time domain window is i-i'0. For example, When RS bundling is applied, i'0 may be determined such that the first slot of one or more slots constituting the actual time domain window is i-i'0.

[0288] For example, Equation 7 does not need to be calculated for each PUSCH transmission opportunity. For example, if PUSCH transmission opportunity i is within a configured time domain window, Equation 7 does not need to be calculated. For example, if PUSCH transmission opportunity i is within a configured time domain window, Equation 7 does not need to be calculated.

[0289] δ PUSCH,b,f,c (m,l), and δ PUSCH,b,f,c (i,l) may be the value of the TPC command. PUSCH,b,f,c (m,l), and δ PUSCH,b,f,c (i,l) is the TPC command field in the DCI The DCI may be a value specified by the value. The DCI may be a DCI for scheduling a PUSCH. The DCI may be a DCI corresponding to DCI format 2_2 with a CRC scrambled by the TPC-PUSCH-RNTI. The DCI may be a DCI corresponding to DCI format 2_3. For example, when the value of the TPC command field is 0, δ in Equation 8 is PUSCH,b,f,c (m, l) may be −1 dB. dB may be decibels. For example, when the value of the TPC command field is 1, δ in Equation 8 PUSCH,b,f,c (m, l) may be 0 dB. For example, when the value of the TPC command field is 2, δ in Equation 8 PUSCH,b,f,c For example, when the value of the TPC command field is 3, δ in Equation 8 can be expressed as: PUSCH,b,f,c For example, if the value of the TPC command field is 0, then δ in Equation 9 PUSCH,b,f,c For example, if the value of the TPC command field is 1, then δ in Equation 9 may be −4 dB.

[0290] D i may be a set of values ​​for one or more TPC commands. i ) may be the number of values ​​included in the set. For example, the set of values ​​for one or more TPC commands may be K PUSCH (i-i0) symbols before and K PUSCH (i) may include the value of a TPC command received between the previous symbol and the previous symbol. i0 may be an integer greater than 0. For example, i0 may be the minimum value that satisfies condition 1. For example, condition 1 may be satisfied when K of PUSCH transmission opportunity i-i0 is PUSCH The symbol (i-i0) symbols before is K PUSCH (i) The symbol may be before the symbol before the symbol.

[0291] For example, if PUSCH transmission is scheduled by DCI, K PUSCH (i) may be the number of OFDM symbols from the last OFDM symbol of the PDCCH corresponding to the DCI to the first OFDM symbol of the PUSCH transmission.

[0292] For example, if PUSCH transmission is configured by the higher layer parameter ConfiguredGrantConfig, K PUSCH (i) is K PUSCH,min For example, K PUSCH,min is N slot symband K2'. For example, K2' may be the K2 with the smallest value among one or more K2s provided by PUSCH-ConfigCommon.

[0293] δ in Equation 9 PUSCH,b,f,c (i,l) is the PUSCH transmission opportunity i. It may be the value of a previously received TPC command. For example, δ in Equation 9 PUSCH,b,f,c (i,l) is the PUSCH signal received up to K' symbols before PUSCH transmission opportunity i. For example, K' may be the value of the last received TPC command among one or more TPC commands received. PUSCH,min For example, K' may be N2, where N2 may be the number of OFDM symbols for PUSCH preparation time. For example, N2 may vary depending on the value of μ. For example, N2 may correspond to PUSCH processing capability.

[0294] If the first PUSCH transmission opportunity i1 and the second PUSCH transmission opportunity i2 are included in one or more slots constituting a configured time domain window, δ PUSCH,b,f,c (i1,l) is the second PUSCH transmission opportunity δ in PUSCH,b,f,c It may be the same as (i2,l).

[0295] If the first PUSCH transmission opportunity i1 and the second PUSCH transmission opportunity i2 are included in one or more slots that make up the actual time domain window, then δ PUSCH,b,f,c (i1,l) is the second PUSCH transmission opportunity δ PUSCH,b,f,c It may be the same as (i2,l).

[0296] 9 is a diagram showing an example of TPC command reception when DMRS bundling according to one aspect of the present embodiment is applied. In a downlink BWP in a downlink carrier, the terminal device 1 receives a PDCCH 950 in slot 910 and a PDCCH 951 in slot 911. In an uplink BWP in an uplink carrier, a PUSCH 920 is transmitted in slot 913, a PUSCH 921 is transmitted in slot 914, and a PUSCH 923 is transmitted in slot 916. A PUSCH 922 does not have to be transmitted in slot 915. For example, the PUSCH 922 may overlap with an uplink channel with a higher priority. For example, even if an instruction to cancel the transmission of the PUSCH 922 is issued, For example, slot 915 may be a slot corresponding to an event.

[0297] 9, configured time domain window 930 includes PUSCH 920, PUSCH 921, PUSCH 922, and PUSCH 923. Actual time domain window 940 and actual time domain window 941 may be configured with slots or OFDM symbols included in configured time domain window 930. Actual time domain window 940 and actual time domain window 941 may not include PUSCH 922.

[0298] PUSCH 920, PUSCH 921, PUSCH 922, and PUSCH 923 may be PUSCH repeated transmissions. For example, the number of repetitions corresponding to the PUSCH repeated transmissions in Figure 9 may be 4. For example, the PUSCH repeated transmissions in Figure 9 may correspond to PUSCH repetition type A. PUSCH 922 may be dropped.

[0299] The DCI included in the PDCCH 950 may schedule the transmission of the PUSCH 920. The DCI included in the PDCCH 950 may include a first TPC command field. The DCI included in the PDCCH 951 may correspond to DCI format 2_2 or DCI format 2_3. For example, the DCI included in the PDCCH 951 may include a second TPC command field. In FIG. 9, tpc-Accumulation may not be provided.

[0300] For example, in a first case, PUSCH 920 may be a PUSCH in a first PUSCH transmission opportunity, PUSCH 921 may be a PUSCH in a second PUSCH transmission opportunity, PUSCH 922 may be a PUSCH in a third PUSCH transmission opportunity, and PUSCH 923 may be a PUSCH in a fourth PUSCH transmission opportunity. In the first case, the transmit power of the PUSCH in the first PUSCH transmission opportunity may be determined based at least on Equation 7 and Equation 8. The transmit power of the PUSCH in the first PUSCH transmission opportunity may be determined based at least on a value of a TPC command in PDCCH 950. The transmit power of the PUSCH in the second PUSCH transmission opportunity may be determined based at least on Equation 7 and Equation 8. The transmit power of the PUSCH in the second PUSCH transmission opportunity may be determined based at least on a value of a TPC command in PDCCH 951.

[0301] For example, in a second case, the set time domain window 930 may be the first PUSCH transmission opportunity. For example, the PUSCHs in the first PUSCH transmission opportunity may be PUSCH 920, PUSCH 921, PUSCH 922, and PUSCH 923. The transmit power of the PUSCHs in the first PUSCH transmission opportunity may be determined based at least on Equation 7 and Equation 8. The transmit power of the PUSCHs in the first PUSCH transmission opportunity may be determined based at least on the value of the TPC command in PDCCH 950. For example, the transmit power of the PUSCHs in the first PUSCH transmission opportunity may be determined without being based at least on the value of the TPC command in PDCCH 951.

[0302] For example, in a third case, the actual time domain window 940 may be the first PUSCH transmission opportunity, and the actual time domain window 941 may be the second PUSCH transmission opportunity. The PUSCH in the first PUSCH transmission opportunity may be PUSCH 920 and PUSCH 921. The PUSCH in the second PUSCH transmission opportunity may be PUSCH 923. The transmit power of the PUSCH in the first PUSCH transmission opportunity may be determined based at least on Equation 7 and Equation 8. The PUSCH transmit power in the first PUSCH transmission opportunity may be determined based at least on the value of the TPC command in the PDCCH 950. The PUSCH transmit power in the second PUSCH transmission opportunity may be determined based at least on the value of the TPC command in the PDCCH 951.

[0303] The problem is to determine the length of the PUSCH transmission opportunity (e.g., N PUSCH symb,b,f,c (i)) is different. Therefore, the BPRE determined based on at least Equation 4 and Equation 5 is different in each case. For example, Means 1 and Means 2 may be used to solve the problem.

[0304] In the means 1, the PUSCH transmission opportunity i may be one or both of a configured time domain window and an actual time domain window. For example, the means 1 may correspond to the second case or the third case in FIG. 9 . For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be a configured time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be determined based on the configured time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be an actual time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be determined based on the actual time domain window. For example, when DMRS bundling is not applied, the PUSCH transmission opportunity i is determined based on slot index n μ s,f It may be determined based on the following.

[0305] In the means 1, the transmit power of the PUSCH may be determined for each PUSCH transmission opportunity. For example, the transmit power of the PUSCH in the PUSCH transmission opportunity i may be determined based at least on Equation 1. For example, the transmit power of the PUSCH in the PUSCH transmission opportunity i may be determined based at least on BPRE. In the means 1, the BPRE may be determined based at least on Equation 4 and Equation 5.

[0306] In the first means, when DMRS bundling is not applied to the PUSCH, the BPRE of the PUSCH may be determined based on at least the first number of OFDM symbols for a PUSCH transmission opportunity. For example, when DMRS bundling is not applied, N PUSCH symb,b,f,c (i) may be a first number of OFDM symbols, for example, the first number of OFDM symbols may be the number of OFDM symbols in one PUSCH transmission opportunity.

[0307] In the first means, when DMRS bundling is applied, the BPRE may be determined based at least on a second number of OFDM symbols. The first number of OFDM symbols may be different from the second number of OFDM symbols. The second number of OFDM symbols may be independent of the PUSCH transmission opportunity. For example, when DMRS bundling is applied, N in Equation 5 may be determined based on at least a second number of OFDM symbols. PUSCH symb,b,f,c (i) may be a second number of OFDM symbols. For example, the second number of OFDM symbols may be the number of OFDM symbols for PUSCH in one slot. For example, the second number of OFDM symbols may be the number of OFDM symbols in one slot. For example, the second number of OFDM symbols may be the number of OFDM symbols for one PUSCH repetition.

[0308] In the first means, when DMRS bundling is applied to the PUSCH, Δ TF,b,f,c (i) may be 0. When DMRS bundling is applied to the PUSCH, the terminal device 1 TF,b,f,c The value of (i) may be set to 0.

[0309] In the means 2, the PUSCH transmission opportunity i may be a slot. For example, the PUSCH transmission opportunity i is a slot index n μ s,f For example, the means 2 may correspond to the first case in Fig. 9. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be a slot. For example, when DMRS bundling is not applied, the PUSCH transmission opportunity i may be a slot. For example, the first PUSCH transmission opportunity when DMRS bundling is applied may be the same as the second PUSCH transmission opportunity when DMRS bundling is not applied.

[0310] In the means 2, the transmit power of the PUSCH may be determined for each PUSCH transmission opportunity. For example, the transmit power of the PUSCH in the PUSCH transmission opportunity i may be determined based at least on Equation 1. For example, the transmit power of the PUSCH in the PUSCH transmission opportunity i may be determined based at least on the BPRE and an accumulated value of one or more TPC commands. The BPRE in the means 2 may be determined based at least on Equation 4 and Equation 5.

[0311] In the means 2, when DMRS bundling is not applied to the PUSCH, the BPRE of the PUSCH may be determined based on at least the number of first OFDM symbols for a PUSCH transmission opportunity. For example, when DMRS bundling is not applied, N PUSCH symb,b,f,c (i) may be a first number of OFDM symbols, for example, the first number of OFDM symbols may be the number of OFDM symbols in one PUSCH transmission opportunity.

[0312] In the means 2, when DMRS bundling is applied to the PUSCH, the BPRE of the PUSCH may be determined based on at least a second number of OFDM symbols for the PUSCH transmission opportunity. The first number of OFDM symbols may be the same as the second number of OFDM symbols. For example, when DMRS bundling is applied, N in Equation 5 may be PUSCH symb,b,f,c (i) may be a second number of OFDM symbols, for example, the second number of OFDM symbols may be the number of OFDM symbols in one PUSCH transmission opportunity.

[0313] In the second means, when DMRS bundling is applied to the PUSCH, Δ TF,b,f,c (i) may be 0. When DMRS bundling is applied to the PUSCH, the terminal device 1 TF,b,f,c The value of (i) may be set to 0.

[0314] In the means 2, the transmission power control based on the value of the TPC command does not have to be determined for each PUSCH transmission opportunity. For example, f in Equation 7 b,f,c (i,l) may not be determined for every PUSCH transmission opportunity i. For example, if DMRS bundling is applied and PUSCH transmission opportunity i corresponds to a slot in a time-domain window, then f b,f,c (i,l) may not be determined. For example, if DMRS bundling is applied and PUSCH transmission opportunity i corresponds to a slot in the time domain window, then f b,f,c (i,l) may not be updated. For example, if DMRS bundling is applied and the PUSCH transmission opportunity i corresponds to a slot other than the first slot of one or more slots in the time domain window, then f b,f,c (i,l) may not be determined. For example, if DMRS bundling is applied and the PUSCH transmission opportunity i corresponds to a slot other than the first slot of one or more slots in the time domain window, then f b,f,c (i, l) may not be updated. For example, when DMRS bundling is applied, f in Equation 7 b,f,c (i,l) may be determined based at least on a time-domain window. For example, when DMRS bundling is applied, one or more f determined at one or more PUSCH transmission opportunities within the time-domain window. b,f,c (i, l) may be the same. b,f,c (i,l) may be determined for each PUSCH transmission opportunity i. For example, if DMRS bundling is applied, i'0 in Equation 7 may not be 0. For example, one or more f determined at one or more PUSCH transmission opportunities within a time-domain window may be used. b,f,c i'0 may be determined so that (i, l) is the same. The time domain window may be a set time domain window. The time domain window may be an actual time domain window. The f b,f,c (i,l) may be the cumulative value of one or more TPC commands.

[0315] In the means 2, f' in the formula 8 b,f,c (i,l) may be determined for each PUSCH transmission opportunity i. b,f,c (i,l) may be the cumulative value of one or more TPC commands.

[0316] In the means 2, when DMRS bundling is not applied, the accumulated value of the one or more TPC commands may be determined based at least on a first PUSCH transmission opportunity. For example, the first PUSCH transmission opportunity may be i. When DMRS bundling is applied and the first PUSCH transmission opportunity corresponds to a first (e.g., first) slot of one or more slots in a time domain window, the accumulated value of the one or more TPC commands may be determined based at least on the first PUSCH transmission opportunity. When DMRS bundling is applied and the first PUSCH transmission opportunity corresponds to a slot other than the first (e.g., first) slot of one or more slots in a time domain window, the accumulated value of the one or more TPC commands may be determined based at least on a second PUSCH transmission opportunity. For example, the second PUSCH transmission opportunity may be a PUSCH transmission opportunity earlier than the first PUSCH transmission opportunity. For example, the second PUSCH transmission opportunity may be i-i'0.
