The first antenna port and the second antenna port being QCLs in terms of beam parameters may mean that a transmission beam assumed by the receiving side for the first antenna port and a transmission beam assumed by the receiving side for the second antenna port are the same (or correspond to each other). The terminal device 1 may assume that the two antenna ports are QCLs if the large-scale characteristics of a channel through which symbols are transmitted at one antenna port can be estimated from the channel through which symbols are transmitted at another antenna port. The two antenna ports being QCLs may mean that the two antenna ports are assumed to be QCLs.

[0239] The upper layer parameters frequencyHopping, frequencyHoppingDCI-0-1, and frequencyHoppingDCI-0-2 may be parameters indicating a frequency hopping scheme for the PUSCH. 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.

[0240] The frequency hopping interval corresponding to intra-slot frequency hopping may be one slot or less. The frequency hopping interval corresponding to inter-slot frequency hopping may be one slot. The frequency hopping interval corresponding to inter-slot frequency hopping may be multiple slots. For example, if DMRS bundling is enabled, the frequency hopping interval corresponding to inter-slot frequency hopping may be multiple slots. The frequency hopping interval corresponding to inter-repetition frequency hopping may be based on nominal repetition. If the frequency hopping interval is multiple slots, inter-slot frequency hopping may be referred to as inter-bundle frequency hopping. For example, if a certain higher layer parameter is enabled, inter-slot frequency hopping may be referred to as inter-bundle frequency hopping. The certain higher layer parameter may be an upper layer parameter for determining whether DMRS bundling is enabled. The certain higher layer parameter may be the upper layer parameter PUSCH-DMRS-Bundling.

[0241] For example, the first higher layer parameter indicating the frequency hopping scheme for PUSCH is slot If the first higher layer parameter indicates inter-slot frequency hopping and a second higher layer parameter is provided, the hopping interval in inter-slot frequency hopping may be one or more slots. For example, if the first higher layer parameter provides inter-slot frequency hopping and a second higher layer parameter is provided, inter-bundle frequency hopping may be applied. For example, the second higher layer parameter may be an upper layer parameter that determines whether DMRS bundling is applied. For example, the second higher layer parameter may be the upper layer parameter PUSCH-DMRS-Bundling.

[0242] For example, the hopping interval (frequency hopping interval) may be provided by a higher layer parameter. For example, if the higher layer parameter indicates N, the resource blocks of the PUSCH are N The N may be switched every slot. The N may be an integer greater than 1. For example, When the higher layer parameter includes one value, the one value may be provided for one or both of the PUSCH and the PUCCH to which inter-bundle frequency hopping is applied, and the one value may be an integer greater than 1. The one value may also be a window length of a configured time-domain window.

[0243] Based at least on the value of the frequency hopping flag field included in the DCI format Whether to perform frequency hopping for the PUSCH whose transmission is instructed by the random access response grant may be determined based on at least 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 frequency hopping flag field being equal to one.

[0244] Intra-slot frequency hopping is applicable to PUSCH transmission in one or more slots. For example, intra-slot frequency hopping may be used for PUSCH repetitive transmission. For PUSCHs where intra-slot frequency hopping is applied, 1 or The resource block arrangement may be switched every several OFDM symbols. For example, for a PUSCH to which intra-slot frequency hopping is applied, the resource block arrangement may be switched between the first hop and the second hop every one or several OFDM symbols. Also, when intra-slot frequency hopping is performed for a PUSCH, the first hop and the second hop may be switched every one or several OFDM symbols. The difference between the position of the first resource block of the first hop and the position of the first resource block of the second hop is RB offset RB offset may be set 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 within one slot. Intra-slot frequency hopping may be performed for PUSCH repetition type A. may be applied to

[0245] Inter-slot frequency hopping is applied to PUSCH transmission in multiple slots. For PUSCH to which inter-slot frequency hopping is applied, The allocation of resource blocks may be switched. For example, inter-slot frequency hopping may be applied to PUSCH repeated transmission. Furthermore, when inter-slot frequency hopping is performed for PUSCH, the allocation of resource blocks 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 is odd, the PUSCH transmission in the given slot may correspond to the second hop. Inter-slot frequency hopping is available for PUSCH repetition type A and PUSCH repetition type B. It may be applied to a PUSCH corresponding to either type B.

[0246] Inter-repetition frequency hopping is applied to PUSCH corresponding to PUSCH repetition type B. For PUSCH where frequency hopping between repetitions is applied, the nominal repetition rate may be Based on the response, the first and second hops may be switched.

[0247] Inter-bundle frequency hopping is applied to PUSCH transmission in multiple slots. For example, inter-bundle frequency hopping may be applied to PUSCH repetitive transmission. For PUSCH to which inter-bundle frequency hopping is applied, resources may be allocated to each bundle. The arrangement of the bundles may be switched. If mapping is performed, the allocation of resource blocks for each bundle is the first hop. The bundle may be switched between the first hop and the second hop. A bundle may be one or more slots. For example, a bundle may be determined by a higher layer parameter. For example, a bundle may be determined based on a repetition count. 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.

[0248] When DMRS bundling is applied, inter-slot frequency hopping is performed for slot index n μ s,f For example, if DMRS bundling is appropriate, the When used, inter-slot frequency hopping is performed for slot index n μ s,f For example, when DMRS bundling is applied, inter-slot frequency hopping may be determined based on slot index n μ s,f and a first higher layer parameter, wherein the first higher layer parameter may provide the number of slots.

[0249] System frame number (SFN)n f is given to the radio frame The system frame number may be a number assigned to a radio frame and / or an index for a radio frame. The system frame number may be composed of 10 bits. At least a portion of the system frame number may be signaled in the MIB. For example, 6 bits (e.g., 6 most significant bits) of the 10-bit system frame number may be signaled in the MIB. At least a portion of the system frame number may be determined based on the PBCH that carries the MIB. For example, 4 bits (e.g., 4 least significant bits) of the 10-bit system frame number may be signaled in the PBCH transport block as part of channel coding.

[0250] 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.

[0251] 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 slots may be configured by the higher layer parameter tdd-UL-DL-ConfigurationCommon. The UL slots may be configured by the higher layer parameter tdd-UL-DL-ConfigurationDedicated. Therefore, it may be set.

[0252] 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.

[0253] The flexible symbols may be OFDM symbols within a certain period that are not configured or indicated as UL symbols or DL ​​symbols. The certain period may be a period given by the upper layer parameter dl-UL-TransmissionPeriodicity. The flexible symbols may be used for PDSCH, PDCCH, PUSCH, PUCCH, or PRACH. It may be an OFDM symbol set or indicated.

[0254] 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.

[0255] The 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. The terminal device 1 that performs DMRS bundling maintains one or both of phase continuity and power consistency between two PUSCHs in a period based on the time domain window. A time domain window may be used to maintain phase continuity and / or power consistency. DMRS bundling may also be referred to as Joint Channel Estimation.

[0256] The time domain window may be a general term for a configured time domain window (also called a nominal time domain window) and an actual time domain window.

[0257] 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, not applying DMRS bundling may mean that the higher layer parameter PUSCH-DMRS-Bundling is not enabled.

[0258] 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.

[0259] 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, the window length may be used as a first PUSCH transmission for multiple PUSCH transmissions in a configured time domain window. Either the first hop or the second hop may correspond. The set time domain window and part or both of the window length may be used for precoding. For example, the precoding applied to multiple PUSCH transmissions in the set time domain window may be the same. The set time domain window and part or both of the window length may be used for terminal adjustment of the terminal device 1. For example, it is not necessary to correct a frequency synchronization error in the set time domain window. For example, it is not necessary to correct a time timing synchronization error in the set time domain window. For example, it is not necessary to make an adjustment related to antenna virtualization in the set time domain window. For example, it is not necessary to make an adjustment of an analog circuit controlled by a digital signal in the set time domain window. For example, it is not necessary to make an adjustment of a high-frequency circuit in the set time domain window. The adjustment of the high-frequency circuit may be some or all of: changing the operating point of a power amplifier, changing the gain of the power amplifier, phase synchronization in an oscillator, phase adjustment of two carriers, phase adjustment in a phase shifter, and stopping power supply to the high-frequency circuit.

[0260] 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.

[0261] One or more window lengths may be configured in the PUSCH-Config. Alternatively, 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 the DCI format. For example, one of the one or more window lengths may be determined based on the time domain resource allocation field included in the DCI. , one of one or more window lengths may be determined.

[0262] In Frequency Division Duplex, when two or more The time-domain windows may be contiguous, for example, the last slot in a first configured time-domain window may be contiguous with the first slot in a second configured time-domain window.

[0263] 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.

[0264] 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.

[0265] The configured time domain window may end based on a certain slot index. For example, n μ s,f If n is the first value, μs,f The configured time domain window may end at the end of the slot corresponding to the first value. The configured time domain window may be applied to the PUSCH transmitted in the slot. The first value may be 0. The value of 1 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 is the second value, then 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.

[0266] 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.

[0267] 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.

[0268] 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 DL slots, gaps exceeding a certain number of OFDM symbols, transmission of a high priority channel, slot format indication, frequency hopping, and cancellation indication. The events may cause power consistency and phase continuity to be disrupted. That is, the events may disrupt power consistency and phase continuity. For example, the events may disrupt power consistency and phase continuity between PUSCH transmissions.

[0269] For example, the slot or OFDM symbol corresponding to the event is a PUSCH repetition transmission. The slot or OFDM symbol corresponding to the event may be a slot or OFDM symbol in which a DL reception opportunity is canceled. For example, the slot or OFDM symbol corresponding to the event may be a DL slot. For example, the slot or OFDM symbol corresponding to the event may be a slot or OFDM symbol including a DL reception opportunity. For example, the slot or OFDM symbol corresponding to the event may be a slot or OFDM symbol in which a high-priority channel is transmitted. For example, the slot corresponding to the event may be a slot designated as a DL slot or a special slot by the slot format instruction. For example, the OFDM symbol corresponding to the event may be an OFDM symbol designated as a DL symbol or a flexible symbol by the slot format instruction. For example, the slot corresponding to the 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, the slot corresponding to the 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, the OFDM symbol corresponding to the 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.

[0270] The actual time domain window may include OFDM symbols in which no PUSCH is transmitted. For example, the actual time domain window may include 13 consecutive OFDM symbols, and the terminal device 1 may not transmit an uplink physical channel or an uplink physical signal during the 13 consecutive OFDM symbols.

[0271] The terminal device 1 may maintain phase continuity and transmit power consistency within the actual time domain window. 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, an uplink physical channel and two OFDM symbols on which an uplink physical signal is transmitted within the actual time domain window may correspond to the same antenna port. For example, the terminal device 1 may determine whether to transmit a first channel on which symbols at an antenna port are transmitted so that the first channel can be deduced 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, when the first channel and the second channel are included in the actual time domain window, the terminal device 1 may transmit the first channel on which symbols at the certain antenna port are transmitted so that the first channel can be estimated from the second channel on which other symbols at the certain antenna port are transmitted. Furthermore, when the first channel and the second channel are not included in the actual time domain window, the terminal device 1 may not transmit the first channel on which symbols at the certain antenna port are 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 precoding parameters for the PUCCH and / or PUSCH within the actual time domain window. For example, the parameter related to precoding may be a precoding matrix for spatial multiplexing.Furthermore, the parameter related to the precoding may be a higher 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 PUSCH repetition 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 a TPC command field may be applied for the first PUSCH in the actual time domain window. Furthermore, a value in a 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 the PUSCH 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 PUSCH repetition in the actual time domain window. Not performing frequency hopping may mean that the PUCCH repetition in the actual time domain window is located 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.

[0272] Uplink power control may determine the power (transmission power) for the PUSCH, PUCCH, SRS, and PRACH.

[0273] 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), where b is the active BWP among one or more BWPs, or , ... j may be 1 or multiple as configured by higher layer parameters. For example, the transmission power P of the PUSCH may be an index to identify one of the multiple parameter sets. PUSCH,b,f,c (i,j,q d ,l) to determine For this purpose, a parameter set identified by index j may be used. l may be a value for identifying the power control adjustment state. For example, if l is 0, the terminal device 1 For example, when l is 1, the terminal device 1 may maintain two power control states. Controlled state may be maintained. d may 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.

[0274] Terminal device 1 transmits PUSCH in active BWP b of carrier f of serving cell c. When transmitting, 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

number

[0275] PUSCH transmission opportunity i is the slot index n μ s,f The PUSCH transmission opportunity i may be a slot. For example, the PUSCH transmission opportunity i is a time slot where transmit power control is performed. For example, if PUSCH transmission opportunity i is the first slot, transmit power control may be performed in the first slot. PUSCH transmission opportunity i for PUSCH repetition type B may be a nominal repetition. PUSCH transmission opportunity i may be determined based on a slot index, a starting OFDM symbol in the slot, and a number of consecutive OFDM symbols.

[0276] The PUSCH transmission opportunity i may be equal to the length of the configured time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be equal to the length of the configured time domain window. The PUSCH transmission opportunity i may be equal to the window length configured by higher layer parameters. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be equal to the window length. The PUSCH transmission opportunity i may be equal to the length of the actual time domain window. For example, when DMRS bundling is applied, the PUSCH transmission opportunity i may be equal to the length of the actual time domain window. The length of the time domain window may be the same as the length of the inter-domain window. For example, the terminal device 1 may recognize / define the length of the set 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.

[0277] 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) is the transmit power for the PUSCH scheduled by DCI may be.

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.

[0283] Δ TF,b,f,c (i) is a transport format, Δ 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

[0284] 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.

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, If the value of δ is 0, PUSCH,b,f,c (m,l) may be -1 dB. dB may be decibels. For example, if the value of the TPC command field is 1, then δ PUSCH,b,f,c (m,l) may be 0 dB. For example, if the value of the TPC command field is 2, then δ PUSCH,b,f,c (m,l) may be 1 dB. For example, the TPC command filter If the value of field is 3, δ PUSCH,b,f,c (m,l) may be 3 dB. For example, if the value of the TPC command field is 0, then δ PUSCH,b,f,c (i,l) is -4dB For example, if the value of the TPC command field is 1, then δ PUSCH,b,f,c (i,l) may be -1 dB.

For example, The K PUSCH (i-i0) symbols before and K PUSCH (i) The value of the TPC command received between the symbol i0 may be an integer greater than 0. For example, i0 may be the minimum value when condition 1 is satisfied. For example, condition 1 is the K PUSCH (i-i0)shi The symbol before the PUSCH transmission opportunity i is K PUSCH (i) Before the symbol before the symbol i0 may be K of PUSCH transmission opportunities i-i0. PUSCH (i-i0) symbols ago is K of PUSCH transmission opportunity i PUSCH (i) It may be the smallest integer before the symbol. i0 is 0 or greater. It may be larger.

[0298] A PUSCH may not be transmitted based on at least transmission opportunity i and transmission opportunity i0. For example, K PUSCH K symbols before PUSCH transmission opportunity i PUSCH (i) A certain PUSCH may not be transmitted until a symbol before. For example, a certain PUSCH may not be transmitted from PUSCH transmission opportunity i-i0 to PUSCH transmission opportunity i. For example, a certain PUSCH may not be transmitted from the PUSCH at PUSCH transmission opportunity i-i0 to the PUSCH at PUSCH transmission opportunity i.

[0299] K PUSCH (i) may be the number of OFDM symbols. PUSCH (i) is for PUSCH transmission The transmit power may be used to determine the transmit power of K PUSCH (i) at least It may be determined based on K PUSCH (i) may be determined by the TPC means 1. In stage 1, K PUSCH (i) may be the number of OFDM symbols between the PDCCH and the PUSCH. 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. For example, K PUSCH (i) may be determined based at least on the first OFDM symbol of the PUSCH repetition (or PUSCH repetition transmission, PUSCH transmission) in PUSCH transmission opportunity i. For example, K PUSCH (i) is the time from the last OFDM symbol of the PDCCH to the PUSCH transmitter may be the number of OFDM symbols up to the first OFDM symbol of the PUSCH transmission in the first PUSCH transmission opportunity i. PUSCH (i1) is the K PUSCH For example, the first K for the first PUSCH in the first PUSCH transmission opportunity i1 may be the same as (i2). PUSCH (i1) is the second K for the second PUSCH in the second PUSCH transmission opportunity PUSCH (i2) For example, the PUSCH in the second PUSCH transmission opportunity i2 may be the same as the first PUSCH transmission opportunity i1. It may be a repetition of the PUSCH at the reception opportunity i1.

[0300] In TPC method 1, PUSCH transmission is configured by the higher layer parameter ConfiguredGrantConfig. If so, K PUSCH (i) is K PUSCH,min For example, K PUSCH,min is N slot symb and K2'. For example, K2' is the value provided by PUSCH-ConfigCommon. It may be the K2 with the smallest value among one or more K2s provided.

[0301] δ PUSCH,b,f,c (i,l) is the value of the TPC command received before PUSCH transmission opportunity i For example, δ PUSCH,b,f,c (i,l) is the number of K' symbols from PUSCH transmission opportunity i. For example, K' may be the value of the last TPC command received among one or more TPC commands received up to the time when K 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 be the PUSCH processing capability. Capability) may also be supported.

[0303] 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 (i,l) is δ for the second PUSCH transmission opportunityPUSCH,b,f,c It may be the same as (i2,l).

[0304] The first transmission opportunity i1 may be a transmission opportunity within a first configured time domain window. PUSCH (i1) may be determined at transmission opportunity i1. In TPC means 2, K PUSCH (i1) is the first configured time at the first transmission opportunity (PUSCH transmission opportunity) i1. The TPC means 2 may determine the K PUSCH (i1 ) may be determined based at least on the second PUSCH transmission opportunity i2. For example, K PUSCH (i1) may be determined based at least on a second PUSCH transmission opportunity i2 in a second configured time domain window. PUSCH (i1) is the K PUSCH It may be the number of OFDM symbols from (i2) symbol before to the first OFDM symbol of PUSCH transmission opportunity i1. For example, K PUSCH (i1) is the K PUSCH (i2)-1 Shin It may be the number of OFDM symbols from before the start of PUSCH transmission opportunity i1 to the first OFDM symbol of PUSCH transmission opportunity i1. For example, K PUSCH (i1) is the K PUSCH It may be the number of OFDM symbols between (i2) symbols before and the first OFDM symbol of PUSCH transmission opportunity i1. For example, K PUSCH (i1) may be the number of OFDM symbols from the last OFDM symbol of the PDCCH to the first OFDM symbol of transmission opportunity i1. For example, K PUSCH (i1) is the time domain It may be the number of OFDM symbols from the last OFDM symbol in the window to the first OFDM symbol of the transmission opportunity i1. PUSCH(i1) may be determined. One higher layer parameter may be the higher layer parameter PUSCH-DMRS-Bundling.

[0305] For example, the first transmit opportunity i1 may be different from the second transmit opportunity i2. The first transmit opportunity i1 may be a later transmit opportunity than the second transmit opportunity i2. If the first transmit opportunity i1 is the same as the second transmit opportunity i2, then K PUSCH (i1) may be determined by the TPC means 1. The first transmission opportunity i1 may not be the first transmission opportunity in the first configured time domain window.

[0306] For example, the first configured time domain window may be the same as the second configured time domain window. If the first configured time domain window is not the same as the second configured time domain window, K PUSCH (i1) is determined by TPC means 1 For example, the PUSCH transmission in the first configured time domain window may be a repetition of the PUSCH transmission in the second configured time domain window. If a PUSCH transmission in a configured time domain window is not a repetition of a PUSCH transmission in a second configured time domain window, K PUSCH (i1) may be determined by the TPC means 1. For example, the first PUSCH and the second PUSCH in the first configured time domain window The first PUSCH (first PUSCH transmission) and the second PUSCH (second PUSCH transmission) may transmit the same transport block in the configured time domain window. The PUSCHs may correspond to the same transport block. For example, the first PUSCH may be transmitted at the first transmission opportunity i1. For example, the transmit power for the first PUSCH may be determined at the first transmission opportunity i1. For example, the second PUSCH may be transmitted at the second transmission opportunity i2. For example, the transmit power for the second PUSCH may be determined at the second transmission opportunity i2. For example, the first PUSCH may be a repetition of the second PUSCH. For example, one configured time domain window may be determined for the first PUSCH and the second PUSCH.

[0307] For example, a first configured time domain window may be For example, one or more slots constituting a first configured time domain window may constitute a second configured time domain window.

[0308] For example, the second PUSCH transmission opportunity i2 is the first PUSCH transmission opportunity in the second configured time domain window. For example, the second PUSCH transmission opportunity i2 may be a PUSCH transmission opportunity for a second PUSCH in the second configured time domain window. The second PUSCH may be an actual repetition in recurrence type B. The second PUSCH may be a nominal repetition in recurrence type B. The second PUSCH may be an actual PUSCH transmission. The second PUSCH may be a PUSCH after dropping or cancellation. The second PUSCH may be a PUSCH transmission taking dropping or cancellation into consideration.
