In Figure 1 this, the wireless communication system is configured to include at least terminal devices 1A to 1C and a base station device 3 (BS#3: Base station #3). Hereinafter, the terminal devices 1A to 1C will also be referred to as terminal device 1 (UE#1: User Equipment #1).

When the base station device 3 is composed of a plurality of transmitting devices, the plurality of transmitting devices may be respectively arranged at different positions.

[0044] The base station device 3 can provide one or more serving cells. A serving cell can be defined as a set of resources for wireless communication. In addition, a serving cell is also referred to as a cell.

[0045] A serving cell may be configured to include at least one downlink component carrier (downlink carrier) and / or one uplink component carrier (uplink carrier). A serving cell may also be configured to include at least two or more downlink component carriers and / or two or more uplink component carriers.

In Figure 2 A, for example, when the subcarrier spacing setting μ is 2 and the CP setting is normal cyclic prefix, N slot symb = 14, N frame，μ slot = 40, N subframe，μ slot = 4. In addition, in Figure 2 B, for example, when the subcarrier spacing setting μ is 2 and the CP setting is extended cyclic prefix, N slot symb = 12, N frame，μ slot = 40, N subframe，μ slot = 4.

[0050] In the wireless communication system of one aspect of the present embodiment, the time unit T c can be used to represent the length in the time domain. The time unit T c is T c = 1 / (Δf max ·N f ). Δf max = 480 kHz. N f = 4096. The constant κ is κ = Δf max ·N f / (Δf ref N f，ref ) = 64. Δf ref is 15 kHz. N f，ref is 2048.

[0051] The transmission of signals in the downlink and / or the transmission of signals in the uplink can be composed of (organized into) wireless frames (system frames, frames) with a length of T f . T f = (Δf max N f / 100)·T s = 10 ms. “·” represents multiplication. The wireless frame is configured to include 10 subframes. The length of the subframe is T sf = (Δf max N f / 1000)·T s = 1 ms. The number of OFDM symbols in each subframe is N subframe，μ symb = Nslot symb N subframe，μ slot 。

[0053] Figure 3 is a diagram showing an example of a method for constructing a resource grid representing one aspect of the present embodiment. Figure 3 The horizontal axis of represents the frequency domain. In Figure 3 , a configuration example of a resource grid for a subcarrier spacing μ1 in a component carrier 300 and a configuration example of a resource grid for a subcarrier spacing μ2 in a certain component carrier are shown. Thus, one or more subcarrier spacings can be set for a certain component carrier. In Figure 3 , it is assumed that μ1 = μ2 - 1, but various aspects of the present embodiment are not limited to the condition of μ1 = μ2 - 1.

[0054] The component carrier 300 is a frequency band having a prescribed width in the frequency domain.

[0055] The point 3000 is an identifier for determining a certain subcarrier. The point 3000 is also referred to as point A. The common resource block (CRB: Common resource block) set 3100 is a set of common resource blocks for setting μ1 of a subcarrier spacing.

[0056] The common resource block in the common resource block set 3100 that includes the point 3000 (the block indicated by the upper right diagonal line in Figure 3 ) is also referred to as the reference point of the common resource block set 3100. The reference point of the common resource block set 3100 can also be the common resource block with index 0 in the common resource block set 3100.

[0057] Offset 3011 is the offset from the reference point of the common resource block set 3100 to the reference point of the resource grid 3001. Offset 3011 is represented by the number of common resource blocks for the set μ1 of subcarrier spacing.

[0059] The common resource block set 3200 is a set of common resource blocks for the set μ2 of subcarrier spacing.

[0060] The common resource block in the common resource block set 3200 that includes point 3000 (the block represented by the upper left diagonal line in Figure 3 ) is also referred to as the reference point of the common resource block set 3200. The reference point of the common resource block set 3200 can also be the common resource block of index 0 in the common resource block set 3200.

[0061] Offset 3012 is the offset from the reference point of the common resource block set 3200 to the reference point of the resource grid 3002. Offset 3012 is represented by the number of common resource blocks for the subcarrier spacing μ2. The resource grid 3002 includes N size，μ grid2，x common resource blocks starting from the reference point of the resource grid 3002.

[0062] Offset 3014 is the offset from the reference point of the resource grid 3002 to the reference point of the BWP 3004 of index i2 (N start，μ BWP，i2 ).

[0063] Figure 4 is a diagram showing a configuration example of the resource grid 3001 representing one aspect of this embodiment. In the Figure 4 resource grid, the horizontal axis is the OFDM symbol index l sym , and the vertical axis is the subcarrier index k sc . The resource grid 3001 includes N size，μ grid1，x N RB sc subcarriers and includes N subframe，μ symb OFDM symbols. Within the resource grid, through the subcarrier index k sc and the OFDM symbol index l symThe determined resources are called resource elements (RE).

[0064] A resource block (RB) includes N RB sc consecutive subcarriers. The resource block is a general term for a common resource block, a physical resource block (PRB), and a virtual resource block (VRB). Here, N RB SC = 12.

[0065] A resource block unit is a set of resources corresponding to one OFDM symbol in a resource block. That is, a resource block unit includes 12 resource elements corresponding to one OFDM symbol in a resource block.

[0066] For the common resource block with a set μ of a certain subcarrier spacing in a certain common resource block set, indexing is added in ascending order starting from 0 in the frequency domain. The common resource block with index 0 for a set μ of a certain subcarrier spacing includes (or competes, coincides with) point 3000. The index n of the common resource block with a set μ of a certain subcarrier spacing μ CRB satisfies n μ CRB = ceil(k sc / N RB sc ) relationship. Here, k sc = 0 subcarrier is a subcarrier having the same center frequency as the subcarrier corresponding to point 3000.

[0067] For the physical resource block with a set μ of a certain subcarrier spacing in a certain BWP, indexing is added in ascending order starting from 0 in the frequency domain. The index n of the physical resource block with a set μ of a certain subcarrier spacing μ PRB satisfies n μ CRB = n μ PRB + N start ，μ BWP，i relationship. Here, N start，μ BWP，i represents the reference point of the BWP with index i.

[0068] A BWP is defined as a subset of the common resource blocks included in the resource grid. The BWP includes N starting from the reference point N of this BWP start，μ BWP，i startingsize，μ BWP，i a common resource block. The BWP configured for a downlink carrier is also referred to as a downlink BWP. The BWP configured for an uplink component carrier is also referred to as an uplink BWP.

[0069] An antenna port can be defined as follows: the channel over which a symbol on the antenna port is conveyed can be inferred from the channel over which another symbol on the same antenna port is conveyed. For example, the channel can correspond to a physical channel. Additionally, the symbol can also correspond to an OFDM symbol. Additionally, the symbol can also correspond to a resource block unit. Additionally, the symbol can also correspond to a resource element.

[0070] When the large scale property of the channel over which a symbol is conveyed on one antenna port can be inferred from the channel over which a symbol is conveyed on another antenna port, the two antenna ports are said to be QCL (Quasi Co-Located). The large scale property can at least include the long-term characteristics of the channel. The large scale property can also at least include a part or all of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial Rx parameters. For the first antenna port and the second antenna port to be QCL with respect to the beam parameters can mean that the receiving beam assumed by the receiving side for the first antenna port is the same as the receiving beam assumed by the receiving side for the second antenna port. For the first antenna port and the second antenna port to be QCL with respect to the beam parameters can also mean that the transmitting beam assumed by the receiving side for the first antenna port is the same as the transmitting beam assumed by the receiving side for the second antenna port. The terminal device 1 can assume that two antenna ports are QCL when the large scale property of the channel over which a symbol is conveyed on one antenna port can be inferred from the channel over which a symbol is conveyed on another antenna port. Two antenna ports being QCL can also mean assuming that two antenna ports are QCL.

Additionally, carrier aggregation may be communication using multiple component carriers that are aggregated. Additionally, carrier aggregation may be communication using multiple downlink component carriers that are aggregated. Additionally, carrier aggregation may be communication using multiple uplink component carriers that are aggregated.

[0073] The radio transceiver unit 30 includes at least a part or all of a radio transmission unit 30a and a radio reception unit 30b. Here, the device configurations of the baseband unit included in the radio transmission unit 30a and the baseband unit included in the radio reception unit 30b may be the same or different. Additionally, the device configurations of the RF unit included in the radio transmission unit 30a and the RF unit included in the radio reception unit 30b may be the same or different. Additionally, the device configurations of the antenna unit included in the radio transmission unit 30a and the antenna unit included in the radio reception unit 30b may be the same or different.

[0074] For example, the radio transmission unit 30a may generate and transmit a baseband signal of PDSCH. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of PDCCH. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of PBCH. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of a synchronization signal. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of PDSCH DMRS. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of PDCCH DMRS. For example, the radio transmission unit 30a may also generate and transmit a baseband signal of CSI-RS. For example, the radio transmission unit 30a may further generate and transmit a baseband signal of DL PTRS.

[0075] For example, the wireless transmission unit 30b can receive a PRACH. For example, the wireless transmission unit 30b can also receive and demodulate a PUCCH. The wireless transmission unit 30b can also receive and demodulate a PUSCH. For example, the wireless transmission unit 30b can also receive a PUCCH DMRS. For example, the wireless transmission unit 30b can also receive a PUSCH DMRS. For example, the wireless transmission unit 30b can also receive a UL PTRS. For example, the wireless transmission unit 30b can also receive an SRS.

[0076] The upper layer processing unit 34 outputs downlink data (transport block) to the wireless transceiver unit 30 (or the wireless transmission unit 30a). The upper layer processing unit 34 performs processing of the MAC (Medium Access Control) layer, the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the RRC layer.

[0077] The medium access control layer processing unit 35 included in the upper layer processing unit 34 performs MAC layer processing.

[0078] The radio resource control layer processing unit 36 included in the upper layer processing unit 34 performs RRC layer processing. The radio resource control layer processing unit 36 manages various setting information / parameters (RRC parameters) of the terminal device 1. The radio resource control layer processing unit 36 sets RRC parameters based on the RRC message received from the terminal device 1.

[0079] The wireless transceiver unit 30 (or the wireless transmission unit 30a) performs processing such as modulation and coding. The wireless transceiver unit 30 (or the wireless transmission unit 30a) generates a physical signal by modulating, coding, and generating a baseband signal (conversion to a time - continuous signal) for the downlink data, and transmits it to the terminal device 1. The wireless transceiver unit 30 (or the wireless transmission unit 30a) can configure the physical signal to a certain component carrier and transmit it to the terminal device 1.

[0080] The wireless transceiver unit 30 (or the wireless reception unit 30b) performs processing such as demodulation and decoding. The wireless transceiver unit 30 (or the wireless reception unit 30b) separates, demodulates, and decodes the received physical signal, and outputs the decoded information to the upper layer processing unit 34. The wireless transceiver unit 30 (or the wireless reception unit 30b) can perform a channel access procedure before the transmission of the physical signal.

[0081] The RF unit 32 converts (down-converts) the signal received via the antenna unit 31 into a baseband signal by quadrature demodulation, and removes unnecessary frequency components. The RF unit 32 outputs the processed analog signal to the baseband unit.

[0082] The baseband unit 33 converts the analog signal input from the RF unit 32 into a digital signal. The baseband unit 33 removes the part equivalent to the CP (Cyclic Prefix) from the converted digital signal, performs a Fast Fourier Transform (FFT) on the signal after removing the CP, and extracts the signal in the frequency domain.

[0083] The baseband unit 33 performs an Inverse Fast Fourier Transform (IFFT) on the data to generate an OFDM symbol, appends a CP to the generated OFDM symbol to generate a digital signal in the baseband, and converts the digital signal in the baseband into an analog signal. The baseband unit 33 outputs the converted analog signal to the RF unit 32.

[0084] The RF unit 32 uses a low-pass filter to remove excess frequency components from the analog signal input from the baseband unit 33, up-converts the analog signal to the carrier frequency, and transmits it via the antenna unit 31. In addition, the RF unit 32 may also have a function of controlling the transmission power. The RF unit 32 is also referred to as a transmission power control unit.

[0085] One or more serving cells (or component carriers, downlink component carriers, uplink component carriers) can be set for the terminal device 1.

[0086] Each of the serving cells set for the terminal device 1 can be any one of a PCell (Primary cell, primary cell), a PSCell (Primary SCG cell, primary SCG cell), and an SCell (Secondary Cell, secondary cell).

[0201] The PUCCH resource indicator field may be a field indicating any index of one or more PUCCH resources included in the PUCCH resource set. The PUCCH resource set may include one or more PUCCH resources.

[0202] DCI format 1_0 may also not include a carrier indicator field. That is to say, the downlink component carrier configured with a PDSCH scheduled by DCI format 1_0 may be the same as the downlink component carrier configured with a PDCCH including this DCI format 1_0.

[0203] DCI format 1_0 may also not include a BWP field. That is to say, the downlink BWP configured with a PDSCH scheduled by DCI format 1_0 may be the same as the downlink BWP configured with a PDCCH including this DCI format 1_0.

[0217] It may be that when the PDSCH_HARQ feedback timing indication field is included in DCI format 1_1, the PDSCH_HARQ feedback timing indication field is at least used to indicate the offset from the time slot of the last OFDM symbol including the PDSCH to the time slot of the OFDM symbol including the start point of the PUCCH. It may also be that when the PDSCH_HARQ feedback timing indication field is not included in DCI format 1_1, the offset from the time slot of the last OFDM symbol including the PDSCH to the time slot of the OFDM symbol including the start point of the PUCCH is determined by a parameter of the upper layer.

[0218] The PUCCH resource indication field may be a field indicating any index among one or more PUCCH resources included in the PUCCH resource set.

[0219] It may be that when the BWP field is included in DCI format 1_1, the BWP field is used to indicate the downlink BWP configured with the PDSCH. It may also be that when the BWP field is not included in DCI format 1_1, the downlink BWP configured with the PDSCH is the same as the downlink BWP of the PDCCH configured with DCI format 1_1 including the scheduling for the PDSCH. It may also be that when the number of downlink BWPs set for the terminal device 1 in a certain downlink component carrier is 2 or more, the number of bits of the BWP field included in DCI format 1_1 for the scheduling of the PDSCH configured for the certain downlink component carrier is 1 bit or more.

[0220] It may be that, when a carrier indicator field is included in DCI format 1_1, the carrier indicator field is used to indicate a downlink component carrier configured with a PDSCH. It may also be that, when a carrier indicator field is not included in DCI format 1_1, the downlink component carrier configured with a PDSCH is the same as the downlink component carrier of a PDCCH configured with DCI format 1_1 including scheduling for the PDSCH. It may also be that, when the number of downlink component carriers assigned to the terminal device 1 in a certain serving cell group is 2 or more (when carrier aggregation of the downlink is applied in a certain serving cell group), the number of bits of the carrier indicator field included in DCI format 1_1 for scheduling the PDSCH configured for the certain serving cell group is 1 bit or more (for example, 3 bits).

[0221] The PDSCH can be used to transmit a transport block. The PDSCH can also be used to transmit a transport block corresponding to the DL-SCH. The PDSCH can be used to deliver a transport block. The PDSCH can also be used to deliver a transport block corresponding to the DL-SCH. A transport block can be configured on the PDSCH. A transport block corresponding to the DL-SCH can also be configured on the PDSCH. The base station device 3 can transmit the PDSCH. The terminal device 1 can receive the PDSCH.

[0222] The downlink physical signal can correspond to a set of resource elements. The downlink physical signal may also not carry information generated at the upper layer. The downlink physical signal can be a physical signal used in a downlink component carrier. The downlink physical signal can be transmitted by the base station device 3. The downlink physical signal can also be transmitted by the terminal device 1. At least a part or all of the following downlink physical signals can be used in the wireless communication system of one aspect of the present embodiment.

[0223] · Synchronization signal (SS)

[0224] · DL DMRS (DownLink DeModulation Reference Signal)

[0225] ·CSI-RS (Channel State Information-Reference Signal)

[0226] ·DL PTRS (DownLink Phase Tracking Reference Signal)

[0227] The synchronization signal can be used at least for the terminal device 1 to obtain the synchronization in the frequency domain and / or time domain of the downlink. The synchronization signal is a general term for the PSS (Primary Synchronization Signal) and the SSS (Secondary Synchronization Signal).

[0228] Figure 7 It is a diagram showing a configuration example of an SS / PBCH block representing a solution of this embodiment. In Figure 7 , the horizontal axis is the time axis (OFDM symbol index l sym ), and the vertical axis represents the frequency domain. In addition, the slanted blocks represent the set of resource elements for the PSS. In addition, the grid blocks represent the set of resource elements for the SSS. In addition, the horizontal blocks represent the set of resource elements for the PBCH and the DMRS for the PBCH (the DMRS associated with the PBCH, the DMRS included in the PBCH, the DMRS corresponding to the PBCH).

[0229] As Figure 7As shown, the SS / PBCH block includes the PSS, SSS, and PBCH. In addition, the SS / PBCH block includes 4 consecutive OFDM symbols. The SS / PBCH block includes 240 subcarriers. The PSS is configured on subcarriers 57 to 183 in the first OFDM symbol. The SSS is configured on subcarriers 57 to 183 in the third OFDM symbol. Subcarriers 1 to 56 in the first OFDM symbol can be set to zero. Subcarriers 184 to 240 in the first OFDM symbol can also be set to zero. Subcarriers 49 to 56 in the third OFDM symbol can also be set to zero. Subcarriers 184 to 192 in the third OFDM symbol can also be set to zero. The PBCH is configured on subcarriers 1 to 240 in the second OFDM symbol that are not configured with the DMRS for the PBCH. The PBCH is configured on subcarriers 1 to 48 in the third OFDM symbol that are not configured with the DMRS for the PBCH. The PBCH is configured on subcarriers 193 to 240 in the third OFDM symbol that are not configured with the DMRS for the PBCH. The PBCH is configured on subcarriers 1 to 240 in the fourth OFDM symbol that are not configured with the DMRS for the PBCH.

[0230] The antenna ports of the PSS, SSS, PBCH, and the DMRS for the PBCH can be the same.

[0231] The PBCH that transmits the symbol in a certain antenna port can be estimated based on the DMRS for the PBCH that is configured for the time slot mapping the PBCH and included in the SS / PBCH block that includes the PBCH.

[0232] DL DMRS is the general term for the DMRS for the PBCH, the DMRS for the PDSCH, and the DMRS for the PDCCH.

[0233] The set of antenna ports of the DMRS for the PDSCH (the DMRS associated with the PDSCH, the DMRS included in the PDSCH, the DMRS corresponding to the PDSCH) can be given based on the set of antenna ports for the PDSCH. That is, the set of antenna ports of the DMRS for the PDSCH can be the same as the set of antenna ports for the PDSCH.

[0234] The transmission of the PDSCH and the transmission of the DMRS for the PDSCH can be indicated (or scheduled) by one DCI format. The PDSCH and the DMRS for the PDSCH can be collectively referred to as the PDSCH. Transmitting the PDSCH can also mean transmitting the PDSCH and the DMRS for the PDSCH.

[0235] The PDSCH can be estimated based on the DMRS for that PDSCH. That is to say, the transmission path of the PDSCH can be estimated based on the DMRS for that PDSCH. If the set of resource elements of the symbol for transmitting a certain PDSCH and the set of resource elements of the symbol for transmitting the DMRS for that certain PDSCH are included in the same precoding resource group (PRG: Precoding Resource Group), then the PDSCH transmitting the symbol of that PDSCH in a certain antenna port can be estimated based on the DMRS for that PDSCH.

[0236] The antenna port for the DMRS related to the PDCCH (DMRS associated with the PDCCH, DMRS included in the PDCCH, DMRS corresponding to the PDCCH) can be the same as the antenna port for the PDCCH.

[0237] The PDCCH can be estimated based on the DMRS for that PDCCH. That is to say, the transmission path of the PDCCH can be estimated based on the DMRS for that PDCCH. If the same precoding is applied (assumed to be applied, assumed applied) to the set of resource elements of the symbol for transmitting a certain PDCCH and the set of resource elements of the symbol for transmitting the DMRS for that certain PDCCH, then the PDCCH transmitting the symbol of that PDCCH in a certain antenna port can be estimated based on the DMRS for that PDCCH.

[0238] BCH (Broadcast CHannel), UL-SCH (Uplink-Shared CHannel), and DL-SCH (Downlink-Shared CHannel) are transport channels. The channels used in the MAC layer are called transport channels. The unit of the transport channel used in the MAC layer is also called a transport block (TB) or a MAC PDU (Protocol Data Unit). HARQ (Hybrid Automatic Repeat reQuest) control is performed for each transport block in the MAC layer. A transport block is the unit of data that the MAC layer delivers to the physical layer. In the physical layer, the transport block is mapped to a codeword and modulation processing is performed for each codeword.

[0239] One UL-SCH and one DL-SCH can be given for each serving cell. The BCH can be given by the PCell. The BCH can also not be given by the PSCell or SCell.

[0240] BCCH (Broadcast Control CHannel), CCCH (Common Control CHannel), and DCCH (Dedicated Control CHannel) are logical channels. For example, BCCH is a channel of the RRC layer for transmitting the MIB or system information. In addition, CCCH (Common Control CHannel) can be used to transmit RRC messages common to multiple terminal devices 1. Here, CCCH can be used, for example, for terminal devices 1 that are not in an RRC connection. In addition, DCCH (Dedicated Control CHannel) can be used at least to transmit RRC messages dedicated to terminal device 1. Here, DCCH can be used, for example, for terminal device 1 in an RRC connection.

[0241] RRC messages include one or more RRC parameters (information elements). For example, an RRC message can include the MIB. In addition, an RRC message can also include system information. In addition, an RRC message can also include a message corresponding to CCCH. In addition, an RRC message can also include a message corresponding to DCCH. An RRC message including a message corresponding to DCCH is also referred to as a dedicated RRC message.

[0242] BCCH in the logical channel can be mapped to BCH or DL-SCH in the transport channel. CCCH in the logical channel can be mapped to DL-SCH or UL-SCH in the transport channel. DCCH in the logical channel can be mapped to DL-SCH or UL-SCH in the transport channel.

[0243] UL-SCH in the transport channel can be mapped to PUSCH in the physical channel. DL-SCH in the transport channel can be mapped to PDSCH in the physical channel. BCH in the transport channel can be mapped to PBCH in the physical channel.

[0244] Upper layer parameters (parameters of the upper layer) are parameters included in RRC messages or MAC CE (Medium Access Control Control Element). That is, upper layer parameters are the general term for the information included in the MIB, system information, messages corresponding to CCCH, messages corresponding to DCCH, and MAC CE.

[0245] The processes performed by terminal device 1 include at least a part or all of the following 5A to 5C.

[0246] 5A) Cell search

[0247] 5B) Random access

[0248] 5C) Data communication

[0249] Cell search is a process for synchronizing with a certain cell related to time domain and frequency domain by the terminal device 1 and detecting a physical cell identity. That is to say, the terminal device 1 can perform synchronization of time domain and frequency domain with a certain cell through cell search and detect the physical cell ID.

[0250] The sequence of PSS is given based on at least the physical cell ID. The sequence of SSS is given based on at least the physical cell ID.

[0251] An SS / PBCH block candidate represents a resource that permits (can, reserves, sets, specifies, has the possibility of) the transmission of an SS / PBCH block.

[0252] The set of SS / PBCH block candidates in a certain semi-wireless frame is also referred to as an SS burst set. The SS burst set is also referred to as a transmission window, an SS transmission window, or a DRS transmission window. The SS burst set is a general term that includes at least a first SS burst set and a second SS burst set.

[0253] The base station device 3 transmits one or more indexed SS / PBCH blocks at a prescribed period. The terminal device 1 can detect at least any one of the one or more indexed SS / PBCH blocks and attempt to decode the PBCH included in the SS / PBCH block.

[0254] Random access is a process that includes at least a part or all of Message 1, Message 2, Message 3, and Message 4.

[0255] Message 1 is a process of transmitting a PRACH by the terminal device 1. The terminal device 1 transmits a PRACH in one PRACH opportunity selected from one or more PRACH opportunities based at least on the index of the SS / PBCH block candidate, where the index of the SS / PBCH block candidate is detected based on cell search.

[0256] The setting of the PRACH opportunity may include at least the PRACH configuration period (PCF) T PCF , the number N of PRACH opportunities included in the time domain of a certain PRACH configuration period PCF RO，t , the number N of PRACH opportunities included in the frequency domain RO，f , the number N of random access preambles allocated to each PRACH opportunity for random access RO preamble , the number N of preambles for contention-based random access (CBRA) allocated to the index of each SS / PBCH block candidate SSB preamble，CBRA and the number N of PRACH opportunities allocated to the index of each SS / PBCH block candidate for contention-based random access SSB RO or some or all of them.

[0257] The time resource and frequency resource of a certain PRACH opportunity may be given based on at least the setting of the PRACH opportunity, either partially or in whole.

[0258] The association between the index of the SS / PBCH block candidate corresponding to the SS / PBCH block detected by the terminal device 1 and the PRACH opportunity may be given based on at least the first bitmap information (the first bitmap) representing the index of the SS / PBCH block candidate actually used for the transmission of the SS / PBCH block. The terminal device 1 may determine the association between the index of the SS / PBCH block candidate corresponding to the SS / PBCH block detected by the terminal device 1 and the PRACH opportunity based on at least the first bitmap information representing the index of the SS / PBCH block candidate actually used for the transmission of the SS / PBCH block. Each element of the first bitmap information may correspond to the index of a certain SS / PBCH block candidate. For example, the first element of the first bitmap information may correspond to the SS / PBCH block candidate with the index of the SS / PBCH block candidate being 0. For example, the second element of the first bitmap information may correspond to the SS / PBCH block candidate with the index of the SS / PBCH block candidate being 1. For example, the L SSB th element of the first bitmap information may correspond to the SS / PBCH block candidate with the index of the SS / PBCH block candidate being L SSB -1. L SSB is the number of SS / PBCH blocks included in an SS burst set (e.g., the first SS burst set).

[0259] Figure 8 This is a diagram showing an example of the setting of PRACH resources for one embodiment of the present embodiment. In Figure 8 , the PRACH setting period T PCF is 40 ms, and the number N PCF RO，t of PRACH opportunities included in the time domain of a certain PRACH setting period is 1, and the number N RO，f of PRACH opportunities included in the frequency domain is set to 2.

[0260] For example, the first bitmap information (ssb-PositionInBurst) indicating the index of the SS / PBCH block candidate actually used for the transmission of the SS / PBCH block is set to {1, 1, 0, 1, 0, 1, 0, 0}.

[0261] Figure 9 This is a diagram showing an example of the relationship (SS-RO association) between the index of the SS / PBCH block candidate and the PRACH opportunity in the case where 1) the number N RO preamble of random access preambles allocated to each PRACH opportunity for random access is 64, 2) the number N SSB preamble，CBRA of preambles allocated to the index of each SS / PBCH block candidate for contention-based random access is 64, 3) the number N SSB RO of PRACH opportunities allocated to the index of each SS / PBCH block candidate for contention-based random access is 1, and 4) the first bitmap information is set to {1, 1, 0, 1, 0, 1, 1, 0}. In Figure 9 , it is assumed that the setting of the PRACH opportunity is the same as Figure 8 . In Figure 9 , it can be that the SS / PBCH block candidate with index 0 corresponds to the PRACH opportunity with index 0 (RO#0), the SS / PBCH block candidate with index 1 corresponds to the PRACH opportunity with index 1 (RO#1), the SS / PBCH block candidate with index 3 corresponds to the PRACH opportunity with index 2 (RO#2), the SS / PBCH block candidate with index 5 corresponds to the PRACH opportunity with index 3 (RO#3), and the SS / PBCH block candidate with index 6 corresponds to the PRACH opportunity with index 4 (RO#4). In Figure 9 , the PRACH relationship period (PRACH AP: PRACH association period) T AP is 120 ms including the PRACH opportunities (RO#0 to RO#5) with indices 0 to 4. In Figure 9In it, the PRACH association pattern period (PRACH APP: PRACH Association Pattern Period) T APP is 160 ms. In Figure 9 it, the PRACH association pattern period includes one PRACH association period.

[0262] Figure 10 It is a diagram showing an example of the relationship between the index of the SS / PBCH block candidate and the PRACH opportunity when 1) the number N of random access preambles allocated to each PRACH opportunity for random access RO preamble is 64, 2) the number N of preambles for contention-based random access allocated to the index of each SS / PBCH block candidate SSB preamble，CBRA is 64, 3) the number N of PRACH opportunities for contention-based random access allocated to the index of each SS / PBCH block candidate SSB RO is 1, and 4) the first bitmap information is set to {1, 1, 0, 1, 0, 1, 0, 0}. In Figure 10 it, it is assumed that the setting of the PRACH opportunity is the same as Figure 8 . In Figure 10 it, it can be that the SS / PBCH block candidate with index 0 corresponds to the PRACH opportunity with index 0 (RO#0) and the PRACH opportunity with index 4 (RO#4), the SS / PBCH block candidate with index 1 corresponds to the PRACH opportunity with index 1 (RO#1) and the PRACH opportunity with index 5 (RO#5), the SS / PBCH block candidate with index 3 corresponds to the PRACH opportunity with index 2 (RO#2) and the PRACH opportunity with index 6 (RO#6), and the SS / PBCH block candidate with index 5 corresponds to the PRACH opportunity with index 3 (RO#3) and the PRACH opportunity with index 7 (RO#7). In Figure 10 it, the PRACH association period T AP is 80 ms including the PRACH opportunities (RO#0 to RO#3) with indices from 0 to 3. In Figure 10 it, the PRACH association pattern period (PRACH APP: PRACH Association Pattern Period) T APP is 160 ms. In Figure 10 it, the PRACH association pattern period includes two PRACH association periods.

[0263] The SS / PBCH block candidate with the smallest index among the N "SS / PBCH block candidates actually used for the transmission of SS / PBCH blocks" indicated by the first bitmap information may correspond to the PRACH opportunity at the starting point (the PRACH opportunity with index 0). The nth index among the N "SS / PBCH block candidates actually used for the transmission of SS / PBCH blocks" indicated by the first bitmap information may correspond to the nth PRACH opportunity (the PRACH opportunity with index n - 1).

[0264] The index of the PRACH opportunity is preferably appended to the frequency axis of the PRACH opportunities included in the PRACH relationship pattern period (Frequency-first time-second).

[0265] When all N "SS / PBCH block candidates actually used for the transmission of SS / PBCH blocks" indicated by the first bitmap information are assigned to correspond to at least one PRACH opportunity, it is configured to include a PRACH setting period corresponding to at least one of the PRACH opportunities corresponding to at least one "SS / PBCH block candidate actually used for the transmission of SS / PBCH blocks". In Figure 9 , the PRACH opportunities corresponding to at least one "SS / PBCH block candidate actually used for the transmission of SS / PBCH blocks" are RO#0 to RO#4, and the PRACH setting period corresponding to at least one of the PRACH opportunities corresponding to at least one "SS / PBCH block candidate actually used for the transmission of SS / PBCH blocks" is three PRACH setting periods from the starting point. In Figure 10 , the PRACH opportunities corresponding to at least one "SS / PBCH block candidate actually used for the transmission of SS / PBCH blocks" are RO#0 to RO#3, and the PRACH setting period corresponding to at least one of the PRACH opportunities corresponding to at least one "SS / PBCH block candidate actually used for the transmission of SS / PBCH blocks" is two PRACH setting periods from the starting point.

[0266] When the largest integer k that satisfies T APP > k * T AP is 2 or more, it is configured that one PRACH relationship pattern period includes k PRACH relationship periods. In Figure 10 , the largest integer k that satisfies T APP > k * T AP is 2. The first PRACH relationship period includes two PRACH setting periods from the starting point, and the second PRACH relationship period includes two PRACH setting periods starting from the third PRACH setting period.

[0267] The terminal device 1 transmits a random access preamble selected from the PRACH opportunities corresponding to the indexes of the SS / PBCH block candidates that detect the SS / PBCH block.

[0268] Message 2 is a process in which the terminal device 1 attempts to detect DCI format 1_0 with a CRC (Cyclic Redundancy Check) scrambled by a RA-RNTI (Random Access-Radio Network Temporary Identifier). The terminal device 1 attempts to detect the PDCCH including this DCI format in the resources indicated based on the settings of the control resource set and the search area set, where the settings of the control resource set and the search area set are given based on the MIB of the PBCH included in the SS / PBCH block detected based on cell search.

[0269] Message 3 is a process of transmitting the PUSCH scheduled by the random access response grant included in the DCI format 1_0 detected through the process of Message 2. Here, the random access response grant is indicated by the MAC CE included in the PDSCH scheduled by this DCI format 1_0.

[0270] The PUSCH scheduled based on the random access response grant is either the Message 3 PUSCH or the PUSCH. The Message 3 PUSCH includes a contention resolution identifier MAC CE. The contention resolution identifier MAC CE includes a contention resolution identifier.

[0271] The retransmission of the Message 3 PUSCH is scheduled by DCI format 0_0 with a CRC scrambled based on TC-RNTI (Temporary Cell-Radio Network Temporary Identifier).

[0272] Message 4 is a process of attempting to detect DCI format 1_0 with a CRC scrambled based on either C-RNTI (Cell-Radio Network Temporary Identifier) or TC-RNTI. The terminal device 1 receives the PDSCH scheduled based on this DCI format 1_0. This PDSCH may include a contention resolution identifier.

[0273] Data communication is a general term for downlink communication and uplink communication.

[0274] In data communication, the terminal device 1 attempts to detect the PDCCH (monitor the PDCCH, surveil the PDCCH) in the resources determined based on the control resource set and the search space set.

[0275] The control resource set is a set of resources composed of a specified number of resource blocks and a specified number of OFDM symbols. In the frequency domain, the control resource set can be composed of contiguous resources (non-interleaved mapping), or can be composed of scattered resources (interleaver mapping).

[0276] The set of resource blocks constituting the control resource set can be represented by a higher layer parameter. The number of OFDM symbols constituting the control resource set can also be represented by a higher layer parameter.

[0277] The terminal device 1 attempts to detect the PDCCH in the search space set. Here, attempting to detect the PDCCH in the search space set can be attempting to detect the candidates of the PDCCH in the search space set, or can be attempting to detect the DCI format in the search space set, or can be attempting to detect the PDCCH in the control resource set, or can be attempting to detect the candidates of the PDCCH in the control resource set, or can also be attempting to detect the DCI format in the control resource set.

[0278] The search space set is defined as a set of candidates of the PDCCH. The search space set can be a CSS (Common Search Space) set, or can be a USS (UE-specific Search Space) set. The terminal device 1 attempts to detect the candidates of the PDCCH in a part or all of the Type 0 PDCCH common search space set, Type 0a PDCCH common search space set, Type 1 PDCCH common search space set, Type 2 PDCCH common search space set, Type 3 PDCCH common search space set, and / or the UE-specific PDCCH search space set.

[0279] The type 0 PDCCH common search space set can be used as the common search space set with index 0. The type 0 PDCCH common search space set can also be the common search space set with index 0.

[0280] The CSS set is the general term for the type 0 PDCCH common search space set, the type 0a PDCCH common search space set, the type 1 PDCCH common search space set, the type 2 PDCCH common search space set, and the type 3 PDCCH common search space set. The USS set is also referred to as the UE-specific PDCCH search space set.

[0281] A certain search space set is associated with (including, corresponding to) a certain control resource set. The index of the control resource set associated with the search space set can be represented by a higher layer parameter.

[0282] For a certain search space set, at least a part or all of 6A to 6C can be represented by a higher layer parameter.

[0283] 6A) PDCCH monitoring periodicity

[0284] 6B) PDCCH monitoring pattern within a slot

[0285] 6C) PDCCH monitoring offset

[0286] The monitoring occasion of a certain search space set can correspond to the OFDM symbol of the OFDM symbol configured with the starting point of the control resource set associated with the certain search space set. The monitoring occasion of a certain search space set can also correspond to the resources of the control resource set starting from the OFDM symbol of the starting point of the control resource set associated with the certain search space set. The monitoring occasion of the search space set is given based on at least a part or all of the PDCCH monitoring periodicity, the PDCCH monitoring pattern within a slot, and the PDCCH monitoring offset.

[0287] Figure 11 It is a diagram showing an example of the monitoring occasion of the search space set representing a solution of this embodiment. In Figure 11 In it, the search space set 91 and the search space set 92 are set in the primary cell 301, the search space set 93 is set in the secondary cell 302, and the search space set 94 is set in the secondary cell 303.

[0288] In Figure 11Among them, the blocks indicated by the grid lines represent the search area set 91, the blocks indicated by the upper right diagonal represent the search area set 92, the blocks indicated by the upper left diagonal represent the search area set 93, and the blocks indicated by the horizontal lines represent the search area set 94.

[0289] Set the monitoring interval of the search area set 91 to 1 time slot, set the monitoring offset of the search area set 91 to 0 time slots, and set the monitoring mode of the search area set 91 to [1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0]. That is to say, the monitoring opportunities of the search area set 91 correspond to the starting OFDM symbol (OFDM symbol #0) and the 8th OFDM symbol (OFDM symbol #7) in each time slot.

[0290] Set the monitoring interval of the search area set 92 to 2 time slots, set the monitoring offset of the search area set 92 to 0 time slots, and set the monitoring mode of the search area set 92 to [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. That is to say, the monitoring opportunities of the search area set 92 correspond to the starting OFDM symbol (OFDM symbol #0) in each even time slot.

[0291] Set the monitoring interval of the search area set 93 to 2 time slots, set the monitoring offset of the search area set 93 to 0 time slots, and set the monitoring mode of the search area set 93 to [0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 0, 0]. That is to say, the monitoring opportunities of the search area set 93 correspond to the 8th OFDM symbol (OFDM symbol #7) in each even time slot.

[0292] Set the monitoring interval of the search area set 94 to 2 time slots, set the monitoring offset of the search area set 94 to 1 time slot, and set the monitoring mode of the search area set 94 to [1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]. That is to say, the monitoring opportunities of the search area set 94 correspond to the starting OFDM symbol (OFDM symbol #0) in each odd time slot.

[0293] The type 0 PDCCH common search area set can be used at least for DCI formats with CRC (Cyclic Redundancy Check) sequences scrambled by SI-RNTI (System Information - Radio Network Temporary Identifier).

[0294] The type 0a PDCCH common search space set can be used at least for DCI formats appended with CRC sequences scrambled by SI-RNTI (System Information - Radio Network Temporary Identifier).

[0295] The type 1 PDCCH common search space set can be used at least for DCI formats appended with CRC sequences scrambled by RA-RNTI (Random Access - Radio Network Temporary Identifier) and / or CRC sequences scrambled by TC-RNTI (Temporary Cell - Radio Network Temporary Identifier).

[0296] The type 2 PDCCH common search space set can be used for DCI formats appended with CRC sequences scrambled by P-RNTI (Paging - Radio Network Temporary Identifier).

[0297] The type 3 PDCCH common search space set can be used for DCI formats appended with CRC sequences scrambled by C-RNTI (Cell - Radio Network Temporary Identifier).

[0298] The UE-specific PDCCH search space set can be used at least for DCI formats appended with CRC sequences scrambled by C-RNTI.

[0299] In downlink communication, the terminal device 1 detects the downlink DCI format. The detected downlink DCI format is used at least for resource allocation of the PDSCH. The detected downlink DCI format is also referred to as a downlink assignment. The terminal device 1 attempts to receive the PDSCH. Based on the PUCCH resource, the HARQ-ACK (HARQ-ACK corresponding to the transport block included in the PDSCH) corresponding to the PDSCH is reported to the base station device 3, where the PUCCH resource is indicated based on the detected downlink DCI format.

[0300] In uplink communication, the terminal device 1 detects the uplink DCI format. The detected DCI format is used at least for resource allocation of the PUSCH. The detected uplink DCI format is also referred to as an uplink grant. The terminal device 1 performs the transmission of the PUSCH.

[0301] The base station device 3 and the terminal device 1 may perform a channel access procedure in the serving cell c and perform the transmission of a transmission wave in the serving cell c. For example, the serving cell c may be a serving cell set in an unlicensed band. The transmission wave is a signal transmitted from the base station device 3 or the terminal device 1 to the medium.

[0302] The base station device 3 and the terminal device 1 may perform a channel access procedure in the carrier f of the serving cell c and perform the transmission of a transmission wave in the carrier f of the serving cell c. The carrier f is a carrier included in the serving cell c. The carrier f may be constituted by a set of resource blocks given based on upper layer parameters.

[0303] The base station device 3 and the terminal device 1 may perform a channel access procedure in the carrier f of the serving cell c and perform the transmission of a transmission wave in a partial bandwidth b of the carrier f of the serving cell c. The partial bandwidth b is a subset of the frequency band included in the carrier f.

[0304] The base station device 3 and the terminal device 1 may perform a channel access procedure in a partial bandwidth b of the carrier f of the serving cell c and perform the transmission of a transmission wave in the carrier f of the serving cell c. Performing the transmission of a transmission wave in the carrier f of the serving cell c may be to transmit a transmission wave in any one of the partial bandwidths included in the carrier f of the serving cell c.

[0305] The base station device 3 and the terminal device 1 may perform a channel access procedure in a partial bandwidth b of the carrier f of the serving cell c and perform the transmission of a transmission wave in the partial bandwidth b of the carrier f of the serving cell c.

[0306] The channel access procedure may be configured to include one or both of a first sensing and a counting process. The first channel access procedure may include the first sensing. The first channel access procedure may also not include the counting process. The second channel access procedure may include at least two of the first sensing and the counting process. The channel access procedure is a name including a part or all of the first channel access procedure and the second channel access procedure.

[0307] After performing the first channel access procedure, a transmission wave including at least an SS / PBCH block can be transmitted. After performing the first channel access procedure, a transmission wave including an SS / PBCH block, a PDSCH carrying broadcast information, a PDCCH including a DCI format for scheduling the PDSCH, and at least a part or all of CSI-RS can also be transmitted. After performing the second channel access procedure, a transmission wave including at least a PDSCH carrying information other than broadcast information can be transmitted. The PDSCH carrying broadcast information can include at least a part or all of the following: a PDSCH carrying system information, a PDSCH carrying paging information, and a PDSCH for random access (Message 2 and / or Message 4).

[0308] The transmission wave including an SS / PBCH block, a PDSCH carrying broadcast information, a PDCCH including a DCI format for scheduling the PDSCH, and at least a part or all of CSI-RS is also referred to as DRS (Discovery Reference Signal). The DRS can be a signal transmitted after the first channel access procedure.

[0309] It can be that, when the period of the DRS is less than or equal to a specified length and the duty cycle of the DRS is less than or equal to a specified value, after performing the first channel access procedure, a transmission wave including the DRS is transmitted. It can also be that, when the period of the DRS exceeds the specified length, after performing the second channel access procedure, a transmission wave including the DRS is transmitted. It can be that, when the duty cycle of the DRS exceeds the specified value, after performing the second channel access procedure, a transmission wave including the DRS is transmitted. For example, the specified length can be 1 ms. In addition, the specified value can be 1 / 20.

[0310] Transmitting a transmission wave after performing a channel access procedure can be based on the channel access procedure. Transmitting a transmission wave after performing a channel access procedure can also be transmitting a transmission wave when a channel can be transmitted based on the channel access procedure.

[0311] The first measurement may be that the Medium is sensed as Idle during one or more LBT slot durations within a defer duration. Here, LBT (Listen Before Talk) may be a process of giving whether the Medium is Idle or Busy based on carrier sensing. Carrier sensing may implement energy detection in the Medium. For example, Busy may be a state where the amount of energy detected by carrier sensing is greater than a specified threshold. In addition, Idle may be a state where the amount of energy detected by carrier sensing is less than the specified threshold. In addition, the amount of energy detected by carrier sensing being equal to the specified threshold may be Idle. In addition, the amount of energy detected by carrier sensing being equal to the specified threshold may also be Busy.

[0312] Idle may be not Busy. Busy may be not Idle.

[0313] The LBT slot duration is the unit of LBT. Whether the Medium is Idle or Busy may be given for each LBT slot duration. For example, the LBT slot duration may be 9 microseconds.

[0314] The defer duration may at least include period T f and one or more LBT slot durations. The length of the defer duration is referred to as T d . For example, period T f may be 16 microseconds.

[0315] Figure 12 is a diagram showing an example of a counting process representing one scheme of the present embodiment. The counting process at least includes a part or all of steps A1 to A6. Step A1 (Step A1) includes an action of setting the value of counter N to N init . Here, N init is a value randomly (or pseudo-randomly) selected from integer values included in the range from 0 to CWp. CWp is the contention window size (CWS: Contention Window Size) for channel access priority p.

[0316] In step A2 (Step A2), it is determined whether the value of counter N is 0. Step A2 includes an action of completing (or ending) the channel access process when counter N is 0. Step A2 includes an action of entering step A3 when counter N is different from 0. Here, Figure 12True in it corresponds to the evaluation formula being true in the step including the action of the determination evaluation formula. In addition, False corresponds to the evaluation formula being false in the step including the action of the determination evaluation formula. In step A2, the evaluation formula corresponds to the counter N = 0.

[0317] For example, step A3 (Step A3) may include the step of decrementing the value of the counter N. Decrementing the value of the counter N may mean subtracting 1 from the value of the counter N. That is to say, decrementing the value of the counter N may mean setting the value of the counter N to N - 1.

[0318] For example, step A3 may include the step of decrementing the value of the counter N when N > 0. In addition, step A3 may also include the step of decrementing the value of the counter N when it is selected that the base station device 3 or the terminal device 1 decrements the counter N. In addition, step A3 may also include the step of decrementing the value of the counter N when N > 0 and it is selected that both the base station device 3 and the terminal device 1 decrement the counter N.

[0319] For example, step A4 (Step A4) may include performing carrier sensing of the medium during the LBT time slot d, and entering the action of step A2 when the LBT time slot d is idle. In addition, step A4 may also include entering the action of step A2 when it is determined by carrier sensing that the LBT time slot d is idle. In addition, step A4 may also include performing carrier sensing during the LBT time slot d, and entering step A5 when the LBT time slot d is busy. In addition, step A4 may also include entering step A5 when it is determined by carrier sensing that the LBT time slot d is busy. Here, the LBT time slot d may be the LBT time slot, and is the next LBT time slot during which carrier sensing has been performed during the counting process. In step A4, the evaluation formula may correspond to the LBT time slot d being idle.

[0320] Step A5 (Step A5) includes the action of performing carrier sensing until it is detected that the medium is busy during a certain LBT time slot included in the deferral period or until it is detected that the medium is idle during all the LBT time slots included in the deferral period.

[0321] Step A6 (Step A6) includes the action of entering step A5 when it is detected that the medium is busy during a certain LBT time slot included in the deferral period. Step A6 includes the action of entering step A2 when it is detected that the medium is idle during all the LBT time slots included in the deferral period. In step A6, the evaluation formula may correspond to the medium being idle during the certain LBT time slot.

[0322] CW min，p Represents the minimum value of the range of acceptable values of the contention window size CWp for the channel access priority p. CW max，p Represents the maximum value of the range of acceptable values of the contention window size CWp for the channel access priority p. The contention window size CWp for the channel access priority p is also referred to as CWp.

[0323] In the case of transmitting a transmission wave including at least a physical channel (e.g., PDSCH) associated with the channel access priority p, CWp is managed by the base station device 3 or the terminal device 1, and CWp is adjusted (the adjustment process of CWp is implemented) before step A1 of the counting process.

[0324] NR-U (New Radio - Unlicensed) can be applied to a certain component carrier. NR-U can also be applied to a certain serving cell. Applying NR-U to a certain component carrier (or a certain serving cell) can at least include a technology (framework, configuration) containing a part or all of the following elements A1 to A6.

[0325] Element A1: Constituting a second SS burst set in the certain component carrier (or the certain serving cell)

[0326] Element A2: The base station device 3 transmits a second SS / PBCH block in the certain component carrier (or the certain serving cell)

[0327] Element A3: The terminal device 1 receives a second SS / PBCH block in the certain component carrier (or the certain serving cell)

[0328] Element A4: The base station device 3 transmits PDCCH in the second type 0 PDCCH common search area set in the certain component carrier (or the certain serving cell)

[0329] Element A5: The terminal device 1 receives PDCCH in the second type 0 PDCCH common search area set in the certain component carrier (or the certain serving cell)

[0330] Element A6: The upper layer parameters associated with NR-U (e.g., fields included in the MIB) represent a first value (e.g., 1)

[0331] NR-U (New Radio - Unlicensed) may not be applied to a certain component carrier. NR-U may also not be applied to a certain serving cell. Not applying NR-U to a certain component carrier (or a certain serving cell) can at least include a technology (framework, configuration) containing a part or all of the following elements B1 to B6.

[0332] Element B1: Constitutes the first SS burst set in a certain component carrier (or a certain serving cell)

[0333] Element B2: The base station device 3 transmits the first SS / PBCH block in a certain component carrier (or a certain serving cell)

[0334] Element B3: The terminal device 1 receives the first SS / PBCH block in a certain component carrier (or a certain serving cell)

[0335] Element B4: The base station device 3 transmits the PDCCH in the first type 0 PDCCH common search area set in a certain component carrier (or a certain serving cell)

[0336] Element B5: The terminal device 1 receives the PDCCH in the first type 0 PDCCH common search area set in a certain component carrier (or a certain serving cell)

[0337] Element B6: The upper layer parameters associated with NR-U (e.g., the fields included in the MIB) represent values different from the first value (e.g., 0)

[0338] A certain component carrier can be set as a licensed band. A certain serving cell can also be set as a licensed band. Here, setting a certain component carrier (or a certain serving cell) as a licensed band can include at least a part or all of the following settings 1 to 3.

[0339] Setting 1: Give upper layer parameters indicating operation in the licensed band to a certain component carrier (or a certain serving cell), or do not give upper layer parameters indicating operation in the unlicensed band to a certain component carrier (or a certain serving cell)

[0340] Setting 2: Set a certain component carrier (or a certain serving cell) to operate in the licensed band, or do not set a certain component carrier (or a certain serving cell) to operate in the unlicensed band

[0341] Setting 3: A certain component carrier (or a certain serving cell) is included in the licensed band, or a certain component carrier (or a certain serving cell) is not included in the unlicensed band

[0342] The licensed band can be a band that requires a wireless station authorization for (expected) terminal devices operating in the licensed band. The licensed band can also be a band that only allows terminal devices manufactured by an operator (entity, business, organization, enterprise) with a wireless station authorization to operate. The unlicensed band can be a band that does not require a channel access procedure before the transmission of physical signals.

[0343] The license-exempt band may be a band that does not require a wireless station to authorize a (prospective) terminal device that operates in the license-exempt band. The license-exempt band may also be a band that allows terminal devices manufactured by some or all of the operators with a wireless station license and / or operators without a wireless station license to operate. The license-exempt band may also be a band that requires a channel access procedure before transmitting a physical signal.

[0344] Whether to apply NR-U in a certain component carrier (or a certain serving cell) can be determined at least based on whether the certain component carrier (or the certain serving cell) is set to a frequency band that can be used in the license-exempt band (for example, a frequency band that can only be used in the license-exempt band). For example, a list of frequency bands designed for NR or carrier aggregation of NR can be specified. For example, it may be that when a certain frequency band is included in one or more frequency bands in the list that can be used in the license-exempt band (for example, a frequency band that can only be used in the license-exempt band), NR-U is applied in the certain frequency band. In addition, it may also be that when a certain frequency band is not included in one or more frequency bands in the list that can be used in the license-exempt band (for example, a frequency band that can only be used in the license-exempt band), NR-U is not applied in the certain frequency band, and normal NR (for example, NR of Release 15 or NR other than NR-U of Release 16) is applied.

[0345] Whether to apply NR-U in a certain component carrier (or a certain serving cell) can be determined at least based on whether the component carrier (or the certain serving cell) is set to a frequency band that can use NR-U (for example, a frequency band that can only use NR-U). For example, when a list of frequency bands designed for the operation of NR or carrier aggregation of NR is specified and one or more frequency bands in the list are specified as frequency bands that can use NR-U (for example, a frequency band that can only use NR-U), if the frequency band set for the component carrier (or the serving cell) is any one of the one or more frequency bands, NR-U can be applied, and if it is a frequency band other than the one or more frequency bands, NR-U cannot be applied, and normal NR (for example, NR of Release 15 or NR other than NR-U of Release 16) can be applied.

[0346] Whether to apply NR-U in a certain component carrier (or a certain serving cell) can also be determined based on information included in system information (e.g., Master Information Block (MIB) or Physical Broadcast Channel (PBCH)). For example, it can be that information indicating whether to apply NR-U is included in the MIB, and when this information indicates the application of NR-U, NR-U is applied to the serving cell corresponding to this MIB. On the other hand, it can also be that when this information does not indicate the application of NR-U, NR-U is not applied to the serving cell corresponding to this MIB, but normal NR is applied. Or, this information can also indicate whether it can be used in an unlicensed band.

[0347] A certain component carrier can be set as an unlicensed band. A certain serving cell can also be set as an unlicensed band. Here, setting a certain component carrier (or a certain serving cell) as an unlicensed band can include at least a part or all of the following settings 4 to 6.

[0348] Setting 4: Give an upper layer parameter indicating operation in the unlicensed band to a certain component carrier (or a certain serving cell)

[0349] Setting 5: Set a certain component carrier (or a certain serving cell) to operate in the unlicensed band

[0350] Setting 6: A certain component carrier (or a certain serving cell) is included in the unlicensed band

[0351] Hereinafter, it is assumed that NR-U is applied or not applied in the component carrier for description. It should be noted that "applying NR-U in the component carrier" can mean "applying NR-U in the serving cell", and "not applying NR-U in the component carrier" can mean "not applying NR-U in the serving cell".

[0352] Figure 13 It is a diagram showing an example related to the configuration of PUSCH in one aspect of the present embodiment. In Figure 13 it, the horizontal axis is the time axis, indicating the OFDM symbol index. In addition, in Figure 13Among them, 1301 is a physical signal, 1302 is the interval for the handover between the downlink and the uplink, and 1303a and 1303b are signals that constitute the uplink physical channel. A certain uplink physical channel 1303 may include at least one or both of 1303a and 1303b. 1303a and 1303b may be configured in the same time slot. 1303a and 1303b may also be configured in different time slots. The terminal device 1 may expect 1303a and 1303b to be configured in the same time slot. The terminal device 1 may also not expect 1303a and 1303b to be configured in different time slots. The base station device 3 may configure 1303a and 1303b in the same time slot. The base station device 3 may also not configure 1303a and 1303b in different time slots.

[0353] The terminal device 1 may perform a channel access procedure in 1302. The terminal device 1 may transmit the uplink physical channel 1303 based on the channel access procedure performed in 1302. For example, the terminal device 1 may transmit the uplink physical channel 1303 when the result of the channel access procedure performed in 1302 is determined that the medium is idle. In addition, the terminal device 1 may also not transmit the uplink physical channel 1303 when the result of the channel access procedure performed in 1303 is determined that the medium is busy.

[0354] For example, 1303a may be constituted by a part of an OFDM symbol. For example, 1303a may be constituted by a signal that is not transmitted in at least a part of an OFDM symbol but is transmitted in another part. For example, 1303a may also be configured to include an OFDM symbol that generates a time-domain signal only in a part of an OFDM symbol.

[0355] The time-domain signal of 1303a may be generated based at least on the content of resource elements included in OFDM symbols other than OFDM symbol #4 (e.g., OFDM symbol #5, etc.). For example, the time-domain signal of 1303a may be generated based at least on the content of resource elements included in the next OFDM symbol of OFDM symbol #4 (that is, OFDM symbol #5).

[0356] Hereinafter, the subcarrier index k sc is also referred to as the subcarrier index k. In addition, the OFDM symbol index l sym is also referred to as the OFDM symbol index l. That is, k can be used to represent the subcarrier index, and l can be used as the OFDM symbol index.

[0357] The time-domain signal s l (t) of the uplink physical channel can be generated by Equation (1).

[0358] [Equation 1]

[0359]

[0360] In formula (1), t represents time. In addition, a k，l represents the content of a resource element determined by subcarrier index k and OFDM symbol index l. Here, the content can be, for example, one or more modulation symbols. In addition, the content can also be a complex value given based on one or more modulation symbols. In addition, in formula (1), j represents the imaginary unit. In addition, π represents the ratio of a circle's circumference to its diameter. In addition, when the CP is set to extended CP, N μ CP，l can be 512κ·2 -μ . In addition, when the CP is set to normal CP and l = 0, N μ CP，l can be 144κ·2 -μ +16κ. In addition, when the CP is set to normal CP and l = 7·2 μ , N μ CP，l can be 144κ·2 -μ +16κ. In addition, when the CP is set to normal CP and l≠0 and l≠7·2 μ , N μ CP，l can be 144κ·2 -μ .

[0361] In addition, in formula (1), k μ 0 can be given by formula (2).

[0362] [Equation 2]

[0363]

[0364] In formula (2), μ0 can be the maximum value of the subcarrier spacing setting μ set for the terminal device 1.

[0365] In formula (1), the domain (or range) of t can be given by formula (3).

[0366] [Equation 3]

[0367]

[0368] In formula (3), when l = 0, t μ start，l can be 0. In addition, when l≠0, t μ start，l can be t μ start，l-1 +(Nμ u +N μ CP，l-1 )T c In addition, N μ u can also be 2048κ·2 -μ .

[0369] The time-domain signal of 1303b can be generated based on Equation (1). That is to say, the time-domain signal of a certain OFDM symbol included in 1303b can be given at least based on the content of the resource elements included in that certain OFDM symbol.

[0370] For the time-domain signal of 1303a, the time-domain signal can be generated based on a method different from the method for generating the time-domain signal of 1303b. For example, the time-domain signal of a certain OFDM symbol included in 1303a can be given at least based on the content of the resource elements included in an OFDM symbol different from that certain OFDM symbol. For example, the time-domain signal of a certain OFDM symbol included in 1303a can also be given at least based on the content of the resource elements included in the next OFDM symbol of that certain OFDM symbol. In addition, the time-domain signal of a certain OFDM symbol included in 1303a can also be given at least based on the content of the resource elements included in a certain OFDM symbol included in 1303b. In addition, the time-domain signal of a certain OFDM symbol included in 1303a can also be given at least based on the content of the resource elements included in the starting OFDM symbol included in 1303b.

[0371] The time-domain signal of the OFDM symbol included in 1303a is also referred to as a floating CP (floating CP). For example, applying a floating CP to the time-domain signal of a certain OFDM symbol can be that the time-domain signal of that certain OFDM symbol is given at least based on the content of the resource elements included in an OFDM symbol different from that certain OFDM symbol. In addition, applying a floating CP to the time-domain signal of a certain OFDM symbol can also be that the time-domain signal of that certain OFDM symbol is given at least based on the content of the resource elements included in the next OFDM symbol of that certain OFDM symbol. In addition, applying a floating CP to a certain OFDM symbol included in 1303a can also be that the time-domain signal of that certain OFDM symbol is given at least based on the content of the resource elements included in a certain OFDM symbol included in 1303a.

[0372] For example, applying a floating CP to a part of the time-domain signal of a certain OFDM symbol can be applying a floating CP to that part of the time-domain signal of that certain OFDM symbol, without generating a time-domain signal other than that part (or generating a time-domain signal with a power or amplitude of 0).

[0373] For example, applying floating CP to all of the time-domain signals of a certain OFDM symbol can be the application of floating CP to all of the time-domain signals of that certain OFDM symbol.

[0374] For example, not applying floating CP to the time-domain signals of a certain OFDM symbol can be given based at least on the content of the resource elements included in that certain OFDM symbol for the time-domain signals of that certain OFDM symbol.

[0375] For example, not applying and not transmitting floating CP to the time-domain signals of a certain OFDM symbol can be not generating the time-domain signals of that certain OFDM symbol (or generating time-domain signals with power or amplitude of 0).

[0376] For example, not applying but transmitting floating CP to the time-domain signals of a certain OFDM symbol can be given based at least on the content of the resource elements included in that certain OFDM symbol for the time-domain signals of that certain OFDM symbol.

[0377] For example, the time-domain signals in the domain of t represented by formula (4) in the time-domain signals of the OFDM symbol with OFDM symbol index l of 1303a can be generated based at least on formula (5).

[0378] [Equation 4]

[0379]

[0380] [Equation 5]

[0381]

[0382] In formula (4), T tx start can be a value different from 0. In addition, T tx start can also be a value greater than 0. For example, T tx start can be N tx start ·T c . In addition, N tx start can be a value different from 0. In addition, N tx start can also be a value greater than 0. The floating CP can be generated based at least on formula (4).

[0383] For example, T tx start can be used to set the interval for the channel access procedure to be implemented before the transmission of the uplink physical channel (e.g., Figure 13 1302 in

[0384] In formula (5), h is an integer different from 0. For example, h can be 1. In addition, h can also be 2. For example, when the subcarrier spacing setting μ is 0 or 1, h can be 1. In addition, when the subcarrier spacing setting μ is 2, h can be 2. In addition, h can be 1 regardless of the subcarrier spacing setting μ.

[0385] Hereinafter, the case where the uplink physical channel 1303 is configured as PUCCH will be described as an example.

[0386] PUCCH can include a first PUCCH format or a second PUCCH format. For example, the first PUCCH format can be used to transmit one or both of HARQ-ACK with 2 bits or less and scheduling request bits. For example, the second PUCCH format can be used to transmit at least UCI with 3 bits or more. Here, the second PUCCH format may not be used to transmit HARQ-ACK with 2 bits and scheduling request bits.

[0387] Figure 14 is a diagram showing a configuration example of the first PUCCH format representing one aspect of the present embodiment. The first PUCCH format is also referred to as PUCCH format 1. In Figure 14 the horizontal axis is the OFDM symbol index. Here, the starting OFDM symbol of the PUCCH (uplink physical channel 1303) is OFDM symbol #2, the terminating OFDM symbol of the PUCCH is OFDM symbol #13, and the number (or length, period) of OFDM symbols of the PUCCH is 12. The DMRS of the PUCCH is configured at the even-numbered OFDM symbol indexes with the starting OFDM symbol of the PUCCH as the 0th OFDM symbol index. In addition, modulation symbols of UCI are configured at the OFDM symbol indexes where the DMRS is not configured in the PUCCH. As Figure 14 shown, the PUCCH can be continuously configured from the starting OFDM symbol to the terminating OFDM symbol.

[0388] For example, when the starting OFDM symbol of the PUCCH configured with the first PUCCH format is the Xth OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)th OFDM symbol, and a floating CP is applied to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured at the even-numbered OFDM symbol indexes with the (X + 1)th OFDM symbol as the 0th OFDM symbol index.

[0389] For example, when the starting OFDM symbol of the PUCCH constituted by the first PUCCH format is the X-th OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)-th OFDM symbol, and no floating CP is applied to the time-domain signal of the X-th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the X-th OFDM symbol as the 0-th OFDM symbol index.

[0390] For example, when the starting OFDM symbol (the X-th OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1, and a part of the time-domain signal of the X-th OFDM symbol is applied with floating CP, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the (X + 1)-th OFDM symbol as the 0-th OFDM symbol index.

[0391] For example, when the starting OFDM symbol (the X-th OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1, and the entire time-domain signal of the X-th OFDM symbol is applied with floating CP, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the (X + 1)-th OFDM symbol as the 0-th OFDM symbol index.

[0392] For example, when the starting OFDM symbol (the X-th OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1, and no floating CP is applied to or transmitted for the time-domain signal of the X-th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the (X + 1)-th OFDM symbol as the 0-th OFDM symbol index.

[0393] For example, when the starting OFDM symbol (the X-th OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1, and floating CP is transmitted without applying it to the time-domain signal of the X-th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the X-th OFDM symbol as the 0-th OFDM symbol index.

[0394] For example, when the start OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a first PUCCH format is given by an RRC parameter, and the number of OFDM symbols of the PUCCH is L given by the RRC parameter, regardless of whether a floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the Xth OFDM symbol as the 0th OFDM symbol index. Here, when a floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the actual start OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0395] For example, when the start OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a first PUCCH format is given by an RRC parameter, the number of OFDM symbols of the PUCCH is L given by the RRC parameter, and a floating CP is applied to a part of the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the Xth OFDM symbol as the 0th OFDM symbol index. Here, the actual start OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0396] For example, when the start OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a first PUCCH format is given by an RRC parameter, the number of OFDM symbols of the PUCCH is L given by the RRC parameter, and a floating CP is applied to all of the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the Xth OFDM symbol as the 0th OFDM symbol index. Here, the actual start OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0397] For example, when the start OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a first PUCCH format is given by an RRC parameter, the number of OFDM symbols of the PUCCH is L given by the RRC parameter, and a floating CP is not applied to and not transmitted for the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the Xth OFDM symbol as the 0th OFDM symbol index.

[0398] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given as L by RRC parameters, and a floating CP is transmitted without applying the time-domain signal of the (X-1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols with even OFDM symbol indices with the (X-1)th OFDM symbol as the 0th OFDM symbol index.

[0399] Figure 15 FIG. is a configuration example of a second PUCCH format showing one aspect of the present embodiment. The second PUCCH format is also referred to as PUCCH format 3. In Figure 15 , the horizontal axis is the OFDM symbol index. Here, the starting OFDM symbol of the PUCCH (uplink physical channel 1303) is OFDM symbol #2, the terminating OFDM symbol of the PUCCH is OFDM symbol #13, and the number (or length, period) of OFDM symbols of the PUCCH is 12. The DMRS of the PUCCH is configured in the 2nd and 8th OFDM symbol indices with the starting OFDM symbol of the PUCCH as the 0th OFDM symbol index. In addition, modulation symbols of UCI are configured in the OFDM symbol indices where the DMRS is not configured in the PUCCH. As Figure 15 shown, the PUCCH can be configured continuously from the starting OFDM symbol to the terminating OFDM symbol.

[0400] The DMRS of the PUCCH constituted by the second PUCCH format can be configured in the OFDM symbols included in a set of prescribed OFDM symbols. The set of prescribed OFDM symbols can be given based on at least the number of OFDM symbols of the PUCCH. For example, when the number of OFDM symbols of the PUCCH is 5, the set of prescribed OFDM symbols can include the 0th and 3rd OFDM symbols. In addition, when the number of OFDM symbols of the PUCCH is 8, the set of prescribed OFDM symbols can include the 1st and 5th OFDM symbols. In addition, when the number of OFDM symbols of the PUCCH is 10, the set of prescribed OFDM symbols can include the 2nd and 7th OFDM symbols. In addition, when the number of OFDM symbols of the PUCCH is 14, the set of prescribed OFDM symbols can include the 3rd and 10th OFDM symbols.

[0401] For example, in the case where the starting OFDM symbol of a PUCCH constituted by a second PUCCH format is the Xth OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)th OFDM symbol, and a floating CP is applied to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols included in a set of specified OFDM symbols with the (X + 1)th OFDM symbol as the 0th OFDM symbol index. The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L.

[0402] For example, in the case where the starting OFDM symbol of a PUCCH constituted by a second PUCCH format is the Xth OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)th OFDM symbol, and a floating CP is not applied to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols included in a set of specified OFDM symbols with the Xth OFDM symbol as the 0th OFDM symbol index. The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L + 1.

[0403] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a second PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given as L + 1 by RRC parameters, and a floating CP is applied to a part of the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols included in a set of specified OFDM symbols with the (X + 1)th OFDM symbol as the 0th OFDM symbol index.

The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L.

[0405] For example, when the starting OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a second PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given as L + 1 by the RRC parameters, and no floating CP is applied to or transmitted for the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured for the OFDM symbols included in a set of specified OFDM symbols with the (X + 1)th OFDM symbol as the 0th OFDM symbol index. The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L.

[0406] For example, when the starting OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a second PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given as L + 1 by the RRC parameters, and a floating CP is transmitted without applying it to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUCCH can be configured for the OFDM symbols included in a set of specified OFDM symbols with the Xth OFDM symbol as the 0th OFDM symbol index. The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L + 1.

[0407] For example, when the starting OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a second PUCCH format is given by RRC parameters and the number of OFDM symbols of the PUCCH is L, regardless of whether a floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured for the OFDM symbols included in a set of specified OFDM symbols with the Xth OFDM symbol as the 0th OFDM symbol index.

The set of the specified OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L.

[0408] For example, in the case where the start OFDM symbol (the Xth OFDM symbol) of a PUCCH constituted by a second PUCCH format is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and a floating CP is applied to a part of the time-domain signal of the (X - 1)th OFDM symbol, the DMRS of the PUCCH can be configured in the OFDM symbols included in a set of specified OFDM symbols with the Xth OFDM symbol as the 0th OFDM symbol index.

The set of the prescribed OFDM symbols can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L + 1.

[0412] In the first PUCCH format, a complex-valued modulation symbol d(0) can be generated by BPSK (Binary Phase Shift Keying) or QPSK (Quadrature Phase Shift Keying) modulation of a block of bits b(0), …, b(M bit - 1). A sequence y(n) of complex-valued modulation symbols can be generated based on at least the modulation symbol and Equation (6).

[0413] [Equation 6]

[0414] y(n) = d(0)·r(n)

[0415] In Equation (6), r(n) represents the n-th element of a certain sequence. Here, the certain sequence can be a low-PAPR sequence (low-Peak-to-Average Power Ratio sequence). Here, PAPR (Peak-to-Average Power Ratio) is a term representing the ratio of the peak power (or maximum power) to the average power of a certain signal. For example, the low-PAPR sequence can be a sequence with an autocorrelation of 0. In addition, the low-PAPR sequence can also be a sequence with an autocorrelation of 0 and giving a signal with a low amplitude. In addition, the low-PAPR sequence can be given by a ZC (Zadoff-Chu) sequence. In addition, in Equation (6), the domain of n can be an integer between 0 and N RB sc - 1.

[0416] y(n) can be spread block-wise based on a spreading sequence w(m). The spread sequence z can be generated based on at least Equation (7).

[0418]

[0419] In Equation (7), m’ is an index associated with frequency hopping. In addition, N PUCCH SF，0 represents an index associated with the spreading factor of the spreading sequence w(m) used for frequency hopping #0. The spreading factor of the spreading sequence w(m) may correspond to the length of the sequence of the spreading sequence w(m). w(m) may be generated based at least on Equation (8). In the case where in-slot frequency hopping is not applied to the PUCCH, the PUCCH may be constituted by frequency hopping #0. In-slot frequency hopping may be frequency hopping of a certain uplink physical channel in a certain time slot.

[0421]

[0422] In Equation (8), j represents the imaginary unit. In addition, π represents pi. is a sequence. N PUCCH SF，m’ represents an index related to the spreading factor of the spreading sequence w(m) used for frequency hopping #m’. The sequence length of may correspond to the spreading factor of the OCC (Orthogonal Cover Code) of the modulation symbols applied to the UCI (Uplink Control Information). The sequence length of may be based at least on N PUCCH SF，m’ The value of is given. That is, The sequence length of may be given for each frequency hopping. N PUCCH SF，m’ The value of may be given based at least on the number of OFDM symbols of the PUCCH.

[0423] For example, when the number of OFDM symbols of the PUCCH is 14 and frequency hopping is not applied, the value of N PUCCH SF，0 may be 7. In addition, when the number of OFDM symbols of the PUCCH is 12 and frequency hopping is not applied, the value of N PUCCH SF，0 may be 6. In addition, when the number of OFDM symbols of the PUCCH is 14 and frequency hopping is applied, the value of N PUCCH SF，0 may be 3, and the value of N PUCCH SF，1 may be 4.

[0455] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, and the number of OFDM symbols of the PUCCH is L, regardless of whether the floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the value N for determining the transmission power of the PUCCHPUCCH symb (i) It may be given based at least on the number of OFDM symbols assumed to be PUCCH being L. Here, when applying a floating CP to the time-domain signal of the (X - 1)th OFDM symbol, the actual start OFDM symbol of the PUCCH may be the (X - 1)th OFDM symbol.

[0456] For example, when the start OFDM symbol (the Xth OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given by RRC parameters as L, and a floating CP is applied to a part of the time-domain signal of the (X - 1)th OFDM symbol, the value N for determining the transmission power for the PUCCH PUCCH symb (i) It may be given based at least on the number of OFDM symbols assumed to be PUCCH being L. Here, the actual start OFDM symbol of the PUCCH may be the (X - 1)th OFDM symbol.

[0457] For example, when the start OFDM symbol (the Xth OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given by RRC parameters as L, and a floating CP is applied to all of the time-domain signal of the (X - 1)th OFDM symbol, the value N for determining the transmission power for the PUCCH PUCCH symb (i) It may be given based at least on the number of OFDM symbols assumed to be PUCCH being L. Here, the actual start OFDM symbol of the PUCCH may be the (X - 1)th OFDM symbol.

[0458] For example, when the start OFDM symbol (the Xth OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by RRC parameters, the number of OFDM symbols of the PUCCH is given by RRC parameters as L, and a floating CP is not applied and not transmitted for the time-domain signal of the (X - 1)th OFDM symbol, the value N for determining the transmission power for the PUCCH PUCCH symb (i) It may be given based at least on the number of OFDM symbols assumed to be PUCCH being L.

[0459] For example, in the case where the start OFDM symbol (the X-th OFDM symbol) of the PUCCH constituted by the first PUCCH format is given by the RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and the floating CP is transmitted without applying the time-domain signal of the (X - 1)-th OFDM symbol, the value N for determining the transmission power for this PUCCH PUCCH symb (i) can be given based on at least assuming that the number of OFDM symbols of the PUCCH is L + 1.

[0460] When the number of bits of the UCI corresponding to the transmission opportunity of the index i is 11 or less, in formula (9), Δ for the second PUCCH format TF，b，f，c (i) is a parameter given based on at least formula (11). That is, the terminal device 1 can determine Δ for the second PUCCH format based on at least formula (11) TF，b，f，c (i) value.

[0462] Δ TF，b，f，c (i) = 10log 10 (K1·(n HARQ-ACK (i) + O SR (i) + O CSI (i)) / N RE (i))

[0463] In formula (11), K1 is 6. In addition, n HARQ-ACK (i) is a value associated with the HARQ-ACK codebook transmitted through the PUCCH corresponding to the transmission opportunity of the index i. Here, the value associated with the HARQ-ACK codebook transmitted through the PUCCH corresponding to the transmission opportunity of the index i can be the number of bits included in this HARQ-ACK codebook. In addition, O SR (i) is the number of bits of the SR transmitted through the PUCCH corresponding to the transmission opportunity of the index i. In addition, O CSI (i) is the number of bits of the CSI transmitted through the PUCCH corresponding to the transmission opportunity of the index i.

[0464] In formula (11), N RE (i) is given by M PUCCH RB，b，f，c (i)·N RB sc，ctrl (i)·N PUCCH symb-UCI，b，f，c (i). Here, N RB sc，ctrl (i) is 12. In addition, N PUCCHsymb-UCI，b，f，c (i) is the number of OFDM symbols of the PUCCH for UCI transmission. Here, the number of OFDM symbols of the PUCCH for UCI transmission may be a value obtained by subtracting the number of OFDM symbols of the DMRS for the PUCCH from the number of OFDM symbols of the PUCCH.

[0465] When the number of bits of the UCI corresponding to the transmission opportunity of index i is 12 or more, in Equation (9), Δ for the second PUCCH format TF，b，f，c (i) is a parameter given at least based on Equation (12).

[0468] In Equation (11), K2 is 2.4. In addition, BPRE(i) is given by (O ACK (i) + O SR (i) + O CSI (i) + O CRC (i)) / N RE (i). BRPE(i) represents the BPRE (Bit Per Resource Element) of the PUCCH corresponding to the transmission opportunity of index i. Here, O ACK (i) is the number of bits of the HARQ-ACK transmitted through the PUCCH corresponding to the transmission opportunity of index i. In addition, O SR (i) is the number of bits of the SR transmitted through the PUCCH corresponding to the transmission opportunity of index i. In addition, O CSI (i) is the number of bits of the CSI transmitted through the PUCCH corresponding to the transmission opportunity of index i. In addition, O CRC (i) is the number of bits of the CRC transmitted or assumed through the PUCCH corresponding to the transmission opportunity of index i. The number of bits of the assumed CRC may be the same as or different from the number of bits of the transmitted CRC.

[0469] In Equation (12), N RE (i) is given by M PUCCH RB，b，f，c (i) · N RB sc，ctrl (i) · N PUCCH symb-UCI，b，f，c (i). Here, N RB sc，ctrl(i) is 12. In addition, N PUCCH symb-UCI，b，f，c (i) is the number of OFDM symbols of the PUCCH for UCI transmission. Here, the number of OFDM symbols of the PUCCH for UCI transmission may be a value obtained by subtracting the number of OFDM symbols of the DMRS for the PUCCH from the number of OFDM symbols of the PUCCH.

[0470] For example, when the starting OFDM symbol of the PUCCH constituted by the second PUCCH format is the X-th OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)-th OFDM symbol, and a floating CP is applied to the time-domain signal of the X-th OFDM symbol, the determined value N of the transmission power for the PUCCH PUCCH symb-UCI，b，f，c (i) may be given based at least on assuming that the number of OFDM symbols of the PUCCH is L.

[0495] The CSI transmitted via PUCCH can be divided into two parts (block, chunk, unit). Herein, the two parts are respectively referred to as CSI part 1 and CSI part 2. In addition, error correction coding can be respectively applied to the two parts. In addition, CRC sequences can be respectively appended to the two parts.

[0496] The first coded bit sequence and the second coded bit sequence can be generated when transmitting CSI part 1 and CSI part 2 via PUCCH. Herein, the first coded bit sequence can be the coded sequence of the UCI including CSI part 1. In addition, the second coded bit sequence can be the coded sequence of the UCI including CSI part 2.

[0497] When transmitting CSI part 1 and CSI part 2 via PUCCH, the terminal device 1 can determine a part or all of the set of first UCI symbols, the set of second UCI symbols, and the set of third UCI symbols. The terminal device 1 can multiplex the first coded bit sequence and the second coded bit sequence at least based on the determined set of UCI symbols. The set of UCI symbols is a general term for the set of first UCI symbols, the set of second UCI symbols, and the set of third UCI symbols.

[0498] Figure 16 It is a diagram showing an example related to the method for determining the set of UCI symbols of one aspect of the present embodiment. In Figure 16 wherein, the PUCCH duration represents the number of OFDM symbols of the PUCCH. In addition, the PUCCH DMRS symbol indices represent the indices of the OFDM symbols configured with the PUCCH DMRS. In addition, N set UCI represents the number of sets of UCI symbols. The first UCI symbol index set (1 st UCI symbol indicesset) S (1) UCI represents the set of indices of the OFDM symbols included in the set of first UCI symbols. The second UCI symbol index set (2 nd UCI symbol indices set) S (2) UCI represents the set of indices of the OFDM symbols included in the set of second UCI symbols. The third UCI symbol index set (3 rd UCI symbol indices set) S (3) UCIA set of indices of OFDM symbols included in a set of third UCI symbols.

[0499] For example, when the starting OFDM symbol of the PUCCH is the X-th OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)-th OFDM symbol, and a floating CP is applied to the time-domain signal of the X-th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that the duration during the PUCCH is L.

[0500] For example, when the starting OFDM symbol of the PUCCH is the X-th OFDM symbol, the terminating OFDM symbol of the PUCCH is the (X + L)-th OFDM symbol, and no floating CP is applied to the time-domain signal of the X-th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that the duration during the PUCCH is L + 1.

[0501] For example, when the starting OFDM symbol of the PUCCH (the X-th OFDM symbol) is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1 given by RRC parameters, and a floating CP is applied to a part of the time-domain signal of the X-th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that the duration during the PUCCH is L.

[0502] For example, when the starting OFDM symbol of the PUCCH (the X-th OFDM symbol) is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1 given by RRC parameters, and a floating CP is applied to the entire time-domain signal of the X-th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that the duration during the PUCCH is L.

[0503] For example, when the starting OFDM symbol of the PUCCH (the X-th OFDM symbol) is given by RRC parameters, the number of OFDM symbols of the PUCCH is L + 1 given by RRC parameters, and no floating CP is applied or transmitted for the time-domain signal of the X-th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that the duration during the PUCCH is L.

[0504] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L + 1 by the RRC parameter, and a floating CP is transmitted without applying it to the time-domain signal of the Xth OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that it is L + 1 during the PUCCH period.

[0505] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter and the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, regardless of whether a floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that it is L during the PUCCH period. Here, in the case where a floating CP is applied to the time-domain signal of the (X - 1)th OFDM symbol, the actual starting OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0506] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and a floating CP is applied to a part of the time-domain signal of the (X - 1)th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that it is L during the PUCCH period. Here, the actual starting OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0507] For example, in the case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and a floating CP is applied to all of the time-domain signal of the (X - 1)th OFDM symbol, the set of UCI symbols for multiplexing the first coded bit sequence and the second coded bit sequence can be given based on at least assuming that it is L during the PUCCH period. Here, the actual starting OFDM symbol of the PUCCH can be the (X - 1)th OFDM symbol.

[0508] For example, in a case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and a floating CP is not applied to and not transmitted for the time-domain signal of the (X - 1)th OFDM symbol, a set of UCI symbols for multiplexing a first coded bit sequence and a second coded bit sequence can be given based on at least assuming L during the PUCCH period.

[0509] For example, in a case where the starting OFDM symbol (the Xth OFDM symbol) of the PUCCH is given by an RRC parameter, the number of OFDM symbols of the PUCCH is given as L by the RRC parameter, and a floating CP is not applied but transmitted for the time-domain signal of the (X - 1)th OFDM symbol, a set of UCI symbols for multiplexing a first coded bit sequence and a second coded bit sequence can be given based on at least assuming L + 1 during the PUCCH period.

[0510] Hereinafter, a case where the uplink physical channel 1303 is configured as a PUSCH will be described as an example.

[0511] The reference location l is used in the configuration of the DMRS of the PUSCH ref . The reference location l ref represents the index of the OFDM symbol where the OFDM symbol index l = 0. For example, for a PUSCH configuration type A (PUSCH mapping type A), the reference location l ref can be the index of the OFDM symbol at the start of the time slot. In addition, for a PUSCH configuration type B (PUSCH mapping type B), the reference location l ref can be the index of the OFDM symbol at the start of the scheduled PUSCH.

[0512] For example, in a case where the starting OFDM symbol of the PUSCH is the Xth OFDM symbol, the terminating OFDM symbol of the PUSCH is the (X + L)th OFDM symbol, and a floating CP is applied to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUSCH can be configured based on at least assuming that the reference location l ref is the index of the (X + 1)th OFDM symbol.

[0513] For example, in a case where the starting OFDM symbol of the PUSCH is the Xth OFDM symbol, the terminating OFDM symbol of the PUSCH is the (X + L)th OFDM symbol, and a floating CP is not applied to the time-domain signal of the Xth OFDM symbol, the DMRS of the PUSCH can be configured based on at least assuming that the reference location l ref is the index of the Xth OFDM symbol.

[0514] For example, in the case where the start OFDM symbol (the X-th OFDM symbol) of the PUSCH is given by the uplink DCI format, the number of OFDM symbols of the PUSCH given by this uplink DCI format is L + 1, and when a floating CP is applied to a part of the time-domain signal of the X-th OFDM symbol, the DMRS of the PUSCH can be based at least on the assumed reference location l ref configured with the index for the (X + 1)-th OFDM symbol.

In addition, in the case where floating CP is applied to PUSCH configuration type B and the starting OFDM symbol of PUSCH is the Xth OFDM symbol given by the uplink DCI format, a part or all of the OFDM symbols with index X - 1 can be applied with floating CP.
