Description

Terminal device, base station device, communication method, and integrated circuit The present invention relates to a terminal device, a base station device, a communication method, and an integrated circuit. This application claims priority based on Japanese Patent Application No. 2016-088914 filed in Japan on April 27, 2016, the content of which is incorporated herein by reference. In the 3GPP (3rd Generation Partnership Project), which is a standardization project, by adopting an OFDM (Orthogonal Frequency-Division Multiplexing) communication method and flexible scheduling of a predetermined frequency / time unit called a resource block, the standardization of Evolved Universal Terrestrial Radio Access (hereinafter referred to as E-UTRA), which enables high-speed communication, has been carried out. In addition, in 3GPP, a method for realizing low-latency communication is being studied by setting the TTI (Transmission Time Interval) shorter than the conventional 1 ms (Non-Patent Document 1). By setting the TTI shorter, it is expected to shorten the RTT (Round Trip Time), which indicates the time from when a signal is transmitted until a response to the signal is received, in the physical layer. Shortening the RTT is expected to particularly improve the throughput of the TCP (Transport Control Protocol) layer, thereby improving the throughput performance of the entire wireless communication system. On the other hand, in E-UTRA, a PUCCH (Physical Uplink Control CHannel) used for transmitting uplink control information is defined in the uplink. Also, as a PUCCH format, a PUCCH format in which the same sequence is repeated in the time direction within a period of 1 ms is defined (Non-Patent Document 2). For example, by using a PUCCH format in which the same sequence is repeated in the time direction, it is possible to expand the communication coverage of the PUCCH. 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; Study on Latency Reduction Techniques for LTE; (Release 14) 3GPP TR 36.881 V0.6.0 (2016-3). 3rd Generation Partnership Project; Technical Specification Group Radio Access Network; Evolved Universal Terrestrial Radio Access (E-UTRA); (Release 12) 3GPP TS 36.213 V12.4.0 (2014-12). However, a method for realizing PUCCH with a TTI of 1 ms or less has not been sufficiently studied.

A communication system (cellular system) in which a base station device (base station, Node B, eNB (eNodeB)) and a terminal device (terminal, mobile station, mobile station device, user device, UE (User equipment)) communicate in a cell will be used for the description. FIG. 1 is a diagram showing a configuration example of a communication system 100 according to this embodiment. The communication system 100 includes a base station device 1, a terminal device 3A, and a terminal device 3B. The terminal devices 3A and 3B are collectively referred to as the terminal device 3. The base station device 1 communicates data (payload, physical layer data, information) with the terminal device 3. The main physical channels and physical signals used in EUTRA and Advanced EUTRA will be described. A channel means a medium used for transmitting a signal, and a physical channel means a physical medium used for transmitting a signal. In this embodiment, the physical channel can be used synonymously with the signal. The physical channels in EUTRA and Advanced EUTRA may be added in the future, or their structure or format may be changed or added, but even if they are changed or added, it will not affect the description of this embodiment. In LTE, EUTRA, and Advanced EUTRA, the radio frame is used to manage the scheduling of physical channels or physical signals. An example of the time length of one radio frame is 10 milliseconds (ms), and an example of one radio frame is composed of 10 subframes. Further, an example of one subframe is composed of 2 slots. That is, an example of the time length of one subframe is 1 ms, and an example of the time length of one slot is 0.5 ms. Also, the resource block is used to manage the minimum unit of scheduling where the physical channel is arranged. An example of a resource block is defined as a certain frequency region composed of a set of a plurality of subcarriers (for example, 12 subcarriers with a subcarrier spacing of 15 kHz) on the frequency axis and a region composed of a certain transmission time interval (TTI (Transmission Time Interval), slot, symbol). Note that one subframe may be referred to as one resource block pair. Also, in LTE, 1 TTI may be defined as one subframe (1 ms). Note that TTI may be defined as a reception time interval on the receiving side. TTI may be defined as a transmission unit or a reception unit of a physical channel or a physical signal. That is, the time length of a physical channel or a physical signal may be defined based on the length of TTI. Also, a subframe may be composed of one sTTI. That is, a subframe may be determined based on the TTI length. The TTI according to this embodiment may be defined by the number of OFDM symbols. FIG. 2 is a diagram showing an example of TTI defined by the number of OFDM symbols. One subframe is composed of a plurality of OFDM symbols. In the example shown in FIG. 2, the number of OFDM symbols is 14. Also, the lengths of the respective OFDM symbols within one subframe may be different. In the example shown in FIG. 2, the first and eighth OFDM symbols from the left are 2208T ｓ seconds, and the other OFDM symbols are 2192T ｓIt is in seconds. Here, Ts is 0.01 / 307200 seconds. Also, the solid arrow indicates the length of the TTI. Note that the length of the OFDM symbol constituting the subframe is not limited to the example shown in FIG. 2. Also, hereinafter, the OFDM symbol, OFDM symbol, and SC-FDMA symbol are also referred to as OS. Also, in the present embodiment, the OFDM symbol and the SC-FDMA symbol may be read interchangeably with each other. For example, the TTI may be defined by the length of 1, 2, 3, 4, 7, 14 OS. Since the length of the OS can take different values within the subframe, the TTI may include multiple TTI lengths. Also, the length of the TTI is not limited to this. One subframe may be composed of a TTI indicated by the length of 1 OS. Hereinafter, the TTI composed of the length of 1 OS is also referred to as a 1-symbol TTI. Also, one subframe may be composed of a TTI indicated by the length of 2 OS. Hereinafter, the TTI indicated by the length of 2 OS is also referred to as a 2-symbol TTI. Also, one subframe may be composed of a TTI indicated by the length of 3 OS and a TTI indicated by the length of 4 OS. The TTI indicated by the length of 3 OS is also referred to as a 3-symbol TTI, and the TTI indicated by the length of 4 OS is also referred to as a 4-symbol TTI. Also, as shown in FIG. 2, when one subframe is composed of a 3-symbol TTI and a 4-symbol TTI, each TTI is also collectively referred to as a 3 / 4-symbol TTI. Also, one subframe may be composed of a TTI indicated by the length of 7 OS. The TTI indicated by the length of 7 OS is also referred to as a 7-symbol TTI or a slot TTI. Also, one subframe may be composed of a TTI indicated by 14 OS. The TTI indicated by 14 OS is also referred to as a 14-symbol TTI or a subframe TTI. Also, all the TTIs according to the present invention are also collectively referred to as sTTI. The TTI length may be defined other than the number of OFDM symbols. For example, the TTI length may be defined based on time, frequency, subcarrier interval, communication method, etc. In EUTRA and Advanced EUTRA, frame configuration types are defined. Frame structure type 1 can be applied to Frequency Division Duplex (FDD). Frame structure type 2 can be applied to Time Division Duplex (TDD). FIG. 3 is a diagram showing an example of a downlink radio frame configuration according to the present embodiment. The downlink uses the OFDM access method. In the downlink, transmitting the downlink signal and / or the downlink physical channel is referred to as downlink transmission. In the downlink, the PDCCH, EPDCCH, Physical Downlink Shared Channel (PDSCH; Physical Downlink Shared CHannel), etc. are allocated. The downlink radio frame is composed of downlink resource block (RB; Resource Block) pairs. This downlink RB pair is a unit for allocating downlink radio resources, and consists of a frequency band (RB bandwidth) and a time band (two slots = one subframe) with a predetermined width. One downlink RB pair is composed of two consecutive downlink RBs (RB bandwidth × slot) in the time domain. One downlink RB is composed of 12 subcarriers in the frequency domain. Also, in the time domain, it is composed of 7 OFDM symbols when a normal cyclic prefix (CP) is added, and 6 OFDM symbols when a cyclic prefix longer than normal is added. The area defined by one subcarrier in the frequency domain and one OFDM symbol in the time domain is called a resource element (RE; Resource Element). The physical downlink control channel is a physical channel on which downlink control information such as a terminal device identifier, scheduling information of the physical downlink shared channel, scheduling information of the physical uplink shared channel, modulation method, coding rate, retransmission parameter, etc. is transmitted. Here, the downlink subframe in one component carrier (CC; Component Carrier) is described, but the downlink subframe is defined for each CC, and the downlink subframes are substantially synchronized between CCs. FIG. 4 is a diagram showing an example of the uplink radio frame configuration according to the present embodiment. The uplink uses the SC-FDMA scheme. In the uplink, transmitting the uplink signal and / or the uplink physical channel is referred to as uplink transmission. That is, uplink transmission can be equivalently expressed as transmission of PUSCH. In the uplink, a Physical Uplink Shared Channel (PUSCH), a PUCCH, etc. are allocated. Also, a uplink reference signal (uplink reference signal) is allocated to a part of PUSCH and PUCCH. The uplink radio frame is composed of uplink RB pairs. This uplink RB pair is a unit for allocation of uplink radio resources, and consists of a frequency band (RB bandwidth) and a time band (two slots = one subframe) with a predetermined width. One uplink RB pair is composed of two uplink RBs (RB bandwidth × slot) that are continuous in the time domain. One uplink RB is composed of 12 subcarriers in the frequency domain. In the time domain, it is composed of 7 SC-FDMA symbols when a normal cyclic prefix is added, and 6 SC-FDMA symbols when a cyclic prefix longer than normal is added. Here, the uplink subframe in one CC is described, but the uplink subframe is defined for each CC. From the perspective of the terminal device, for correction of propagation delay, etc., the start of the uplink radio frame (uplink subframe) is adjusted to be ahead of the start of the downlink radio frame (downlink subframe). The synchronization signal is composed of three types of primary synchronization signals and a secondary synchronization signal composed of 31 types of codes arranged alternately in the frequency domain. The combination of the signals of the primary synchronization signal and the secondary synchronization signal indicates 504 cell identifiers (Physical Cell Identity; PCI) for identifying the base station device 1 and frame timing for radio synchronization. The terminal device 3 specifies the physical cell ID of the synchronization signal received by cell search. The Physical Broadcast Channel (PBCH; Physical Broadcast Channel) is transmitted for the purpose of notifying (setting) control parameters (broadcast information (system information); System information) commonly used in the terminal device 3 within the cell. The radio resources on which the broadcast information is transmitted on the physical downlink control channel are notified to the terminal device 3 within the cell, and the broadcast information not notified by the physical broadcast channel is transmitted as a layer 3 message (system information) that notifies the broadcast information by the physical downlink shared channel in the notified radio resources. As the broadcast information, a Cell Global Identifier (CGI; Cell Global Identifier) indicating a cell-specific identifier, a Tracking Area Identifier (TAI; Tracking Area Identifier) for managing a paging waiting area, random access setting information (such as a transmission timing timer), common radio resource setting information in the cell, neighboring cell information, uplink access restriction information, etc. are notified. The downlink reference signal is classified into a plurality of types according to its use. For example, the cell-specific RS (Cell-specific reference signals) is a pilot signal transmitted at a predetermined power for each cell, and is a downlink reference signal that is periodically repeated in the frequency domain and time domain based on a predetermined rule. The terminal device 3 measures the reception quality for each cell by receiving the cell-specific RS. Also, the terminal device 3 uses the cell-specific RS as a reference signal for demodulating the physical downlink control channel or the physical downlink shared channel transmitted simultaneously with the cell-specific RS. The sequence used for the cell-specific RS is a sequence that can be identified for each cell. In addition, the downlink reference signal is also used for estimating the propagation path variation of the downlink. The downlink reference signal used for estimating the propagation path variation is referred to as Channel State Information Reference Signals (CSI-RS). Further, the downlink reference signal individually set for the terminal device 3 is referred to as UE specific Reference Signals (URS), Demodulation Reference Signal (DMRS), or Dedicated RS (DRS), and is referred to for channel propagation path compensation processing when demodulating the enhanced physical downlink control channel or the physical downlink shared channel. Before transmitting and receiving downlink data (PDSCH, DL-SCH) and layer 2 messages and layer 3 messages (such as paging and handover commands) which are upper layer control information, the terminal device 3 needs to monitor the physical downlink control channel addressed to the own device, and by receiving the physical downlink control channel addressed to the own device, obtain radio resource allocation information called an uplink grant at the time of transmission and a downlink grant (downlink assignment) at the time of reception from the physical downlink control channel. Note that, in addition to being transmitted by the above-described OFDM symbols, the physical downlink control channel can also be configured to be transmitted in the area of a resource block individually (dedicated) allocated from the base station device 1 to the terminal device 3. Note that the uplink grant can be paraphrased as a DCI format for scheduling the PUSCH. Note that the downlink grant can be paraphrased as a DCI format for scheduling the PDSCH. The subframe in which the PDSCH is scheduled is the subframe in which the decoding of the DCI format instructing the reception of the PDSCH has succeeded. Also, the subframe in which the PUSCH is scheduled is indicated in association with the subframe in which the decoding of the DCI format instructing the transmission of the PUSCH has succeeded. For example, in the case of an FDD cell, the subframe in which the PUSCH is scheduled is 4 subframes after the subframe in which the decoding of the DCI format instructing the transmission of the PUSCH has succeeded. That is, the subframes in which the PUSCH and PDSCH are scheduled are associated with the subframe in which the decoding of the DCI format instructing the transmission or reception has succeeded. The Physical Downlink Control Channel (PDCCH; Physical Downlink Control Channel) is transmitted in several OFDM symbols (e.g., 1 to 4 OFDM symbols) from the beginning of each subframe. The Enhanced Physical Downlink Control Channel (EPDCCH; Enhanced Physical Downlink Control Channel) is a physical downlink control channel arranged in the OFDM symbols where the Physical Downlink Shared Channel PDSCH is arranged. The PDCC or EPDCCH is used for the purpose of notifying the terminal device 3 of radio resource allocation information according to the scheduling of the base station device 1 and information indicating the adjustment amount of the increase or decrease of the transmission power. Hereinafter, when simply described as the Physical Downlink Control Channel (PDCCH), unless otherwise specified, it means both physical channels of the PDCCH and the EPDCCH. The PDCC may be used to transmit Downlink Control Information (DCI). The DCI transmitted by the PDCC includes a downlink grant and an uplink grant. The DCI includes scheduling information for uplink subframes and downlink subframes. The DCI can include scheduling information for uplink and / or downlink sTTIs. That is, the base station device 1 can notify the terminal device 3 of an uplink grant and / or a downlink grant for the sTTI by transmitting the DCI. In the present embodiment, the DCI including an uplink grant and / or a downlink grant for the sTTI is also referred to as sDCI. The sDCI can be transmitted by the PDCC. Also, the sTTI can be transmitted by an area other than the PDCC. In the present embodiment, an area other than the PDCC having a function of transmitting the sDCI is also referred to as sPDCC. For example, the sPDCC may be included between the first OS and N ｓＰＤＣＣＨ up to the sTTI. Also, for example, the sPDCC may be included in a part of the band of the sTTI. A CRC (Cyclic Redundancy Check) parity bit is added to the DCI format. The CRC parity bit added to the downlink grant or the uplink grant may be scrambled with a C-RNTI (Cell-Radio Network Temporary Identifier) or an SPS C-RNTI (Semi Persistent Scheduling Cell-Radio Network Temporary Identifier). The C-RNTI and the SPS C-RNTI are identifiers for identifying a terminal device within a cell. The C-RNTI is used to control the PDSCH or the PUSCH in a single subframe. The SPS C-RNTI is used to periodically allocate resources for the PDSCH or the PUSCH. The CRC parity bit added to the downlink grant or the uplink grant for the sTTI may be scrambled with the C-RNTI or the SPS-RNTI. Further, the CRC parity bit added to the downlink grant or the uplink grant for the sTTI may be scrambled with an RNTI (for example, an RNTI dedicated to the sTTI, etc.) used to allocate the sTTI. The following describes the method for a downlink grant or an uplink grant for sTTI. The base station apparatus 1 can, for example, divide and transmit information included in a downlink grant or an uplink grant. For example, the base station apparatus 1 may have a function of transmitting a first DCI (Slow Grant, First Grant, etc.) and a second DCI (Fast Grant, Second Grant) to the terminal apparatus 3. The first DCI may indicate candidates for resources of sPDSCH or sPUSCH to which the terminal apparatus 3 is assigned. The first DCI may include information regarding allocation information of sPDSCH or sPUSCH, MCS, TTI length, etc. The first DCI may include information indicating resources (frequency band, period, number of RBs, RB index, etc.) for which allocation by a downlink grant or an uplink grant for sTTI is applied. The CRC parity bits added to the first DCI may be scrambled with an RNTI shared by a plurality of terminal apparatuses 3. The second DCI may include information regarding decoding of the allocated sPDSCH or sPUSCH in the resources for sTTI pre-allocated by the first DCI. For example, the second DCI may include a downlink resource allocation indicating the RBs used for data transmission, information used for HARQ control, etc. The DCI may be used for transmission of a plurality of TPC (Transmission Power Control) commands for the PUSCH of the primary cell or a plurality of TPC commands for the PUCCH of the primary cell. A plurality of TPC commands for the PUSCH and / or PUCCH of the primary cell are included in DCI format 3 or DCI format 3A. One TPC command included in DCI format 3 is 2 bits. One TPC command included in DCI format 3A is 1 bit. The base station device 1 transmits an upper layer signal including information indicating the value of TPC-PUSCH-RNTI, information indicating the parameter tpc-index corresponding to TPC-PUSCH-RNTI, information indicating the value of TPC-PUCCH-RNTI, and information indicating the parameter tpc-index corresponding to TPC-PUCCH-RNTI to the terminal device 3. The base station device 1 transmits an upper layer signal including information instructing the monitoring of DCI format 3 or DCI format 3A to the terminal device 3. The CRC parity bits added to DCI format 3 / 3A are scrambled by TPC-PUSCH-RNTI or TPC-PUCCH-RNTI. When the CRC parity bits added to DCI format 3 / 3A are scrambled by TPC-PUSCH-RNTI, the terminal device 3 determines that the DCI format 3 / 3A includes a TPC command for PUSCH. When the CRC parity bits added to DCI format 3 / 3A are scrambled by TPC-PUCCH-RNTI, the terminal device 3 determines that the DCI format 3 / 3A includes a TPC command for PUCCH. The DCI format 3 / 3A with CRC parity bits scrambled by TPC-PUSCH-RNTI is also referred to as the DCI format 3 / 3A for PUSCH. The DCI format 3 / 3A with CRC parity bits scrambled by TPC-PUCCH-RNTI is also referred to as the DCI format 3 / 3A for PUCCH. The terminal device 3 determines the index of the TPC command for the terminal device 3 based on the parameter tpc-index given by the upper layer. The base station device 1 may transmit DCI format 3 / 3A in the CSS (Common Search Space) of the primary cell. The terminal device 3 may monitor DCI format 3 / 3A in the CSS of the primary cell. The terminal device 3 may attempt to decode the PDCCH / EPDCCH for DCI format 3 / 3A in the CSS of the primary cell. The downlink grant includes a TPC command for PUCCH. The uplink grant includes a TPC command for PUSCH. The Physical Uplink Control Channel (PUCCH; Physical Uplink Control Channel) is used to perform an acknowledgment response (HARQ-ACK; Hybrid Automatic Repeat reQuest-Acknowledgment or ACK / NACK; Acknowledgment / Negative Acknowledgment) for downlink data transmitted on the physical downlink shared channel, downlink propagation path (channel state) information (CSI; Channel State Information), and an uplink radio resource allocation request (radio resource request, scheduling request (SR; Scheduling Request)). When an acknowledgment response is transmitted in a subframe or (s) TTI in which a scheduling request is expected (or set) to be transmitted, the transmission of a scheduling request in the subframe or the (s) TTI is also referred to as a positive SR (Positive SR), and the non-transmission of a scheduling request in the subframe or the (s) TTI is also referred to as a negative SR (Negative SR). That is, the terminal device 3 can transmit a positive SR or a negative SR in a subframe or (s) TTI in which the transmission of a scheduling request is expected (or set) to be transmitted. CSI includes the receiving quality indicators (CQI: Channel Quality Indicator), precoding matrix indicators (PMI: Precoding Matrix Indicator), precoding type indicators (PTI: Precoding Type Indicator), and rank indicators (RI: Rank Indicator) corresponding to the CSI, and can be used to specify (represent) a suitable modulation method and coding rate, a suitable precoding matrix, a suitable type of PMI, and a suitable rank, respectively. Each Indicator may be denoted as Indication. Also, CQI and PMI are classified into wideband CQI and PMI assuming transmission using all resource blocks in one cell, and subband CQI and PMI assuming transmission using some consecutive resource blocks (subbands) in one cell. In addition to the normal type of PMI that represents one suitable precoding matrix with one PMI, there is a type of PMI that represents one suitable precoding matrix using two types of PMI, the first PMI and the second PMI. For example, the terminal device 3 occupies a group of downlink physical resource blocks and reports the CQI index that satisfies the condition that the error probability of one PDSCH transport determined by the combination of the modulation method and the transport block size corresponding to the CQI index does not exceed a predetermined value (for example, 0.1). Note that the downlink physical resource blocks used for the calculation of CQI, PMI, and / or RI are also referred to as CSI reference resources (CSI reference resource). The terminal device 3 reports CSI to the base station device 1. The CSI report includes a periodic CSI report and an aperiodic CSI report. In the periodic CSI report, the terminal device 3 reports CSI at the timing set in the upper layer. In the aperiodic CSI report, the terminal device 3 reports CSI at the timing based on the CSI request information included in the received uplink DCI format (uplink grant) or random access response grant. The terminal device 3 reports CQI and / or PMI and / or RI. Note that the terminal device 3 may not report PMI and / or RI depending on the upper layer setting. The upper layer setting is, for example, a parameter such as a transmission mode, a feedback mode, a report type, and whether to report PMI / RI. FIG. 5 is a diagram showing a method for generating PUCCH according to this embodiment. In FIG. 5, N PUCCH SF is the spreading factor of the orthogonal sequence w(i) within a single slot, and is 4. In FIG. 5, N PUCCH seq is the number of subcarriers included in the bandwidth of a single PUCCH, and is 12. In FIG. 5, p is the antenna port number, and P is the number of antenna ports used for PUCCH transmission. First, the terminal device 3 determines the sequence r’ u,v (n). u is the sequence group number. The terminal device 3 may determine the value of u based on at least the physical layer cell identity. v is the sequence number, and is always 0 for PUCCH. Note that the sequence group number u may hop every slot based on a pseudo-random sequence. The base station device 1 transmits information indicating whether the hopping of the sequence group number u is valid. Also, the terminal device 3 determines whether to hop the sequence group number u based on the information indicating whether the hopping of the sequence group number u is valid. The terminal device 3 and the base station device 1 receive a sequence r′ of sequence length 12 defined for each sequence group number. u,v (n) and the sequence r' corresponding to the determined u u,v Read (generate) (n). The terminal device 3 receives the sequence r' u,v (n) to ej αpｎ By multiplying with the sequence r (αp) u,v Generate (n). α p is the phase rotation for each subcarrier. u,v The phase rotation of (n) corresponds to a cyclic shift of the SC-FDMA symbol of the PUCCH in the time domain. p is also simply referred to as a cyclic shift. The terminal device 3 receives the sequence r (αp) u,v (n) by 1 / √P and d(0) to obtain a block of modulation symbols y (p) d(0) is a modulation symbol generated by modulating each of the 1-bit or 2-bit HARQ-ACK with binary phase shift keying (BPSK) or quadrature phase shift keying (QPSK). The terminal device 3 receives a block of modulation symbols y (p) (n) to S(n s ) and then multiply S(n s ) multiplied by the block of modulation symbols y (p) (n) is the orthogonal sequence w n(p)OC (m) to obtain a block of modulation symbols z (p) Generate (*). S(n s ) is set to 1 or e based on the number of PUCCH resources. jπ / 2 is selected. The terminal device 3 divides a block z of modulation symbols in a subframe. (p)(*) is placed in the SC-FDMA symbols of {0, 1, 5, 6} in the first slot, and then placed in the SC-FDMA symbols of {0, 1, 5, 6} in the second slot. In a single SC-FDMA symbol, z (p) (*) is placed in order from the subcarriers with smaller numbers. Hereinafter, a method for generating DMRS will be described. FIG. 6 is a diagram showing a method for generating a sequence of DMRS according to the present embodiment. In FIG. 6, N PUCCH RS is the number of SC-FDMA symbols used for transmitting DMRS for PUCCH for each single slot, and is 3. In FIG. 6, M RS SC is the length of the reference signal sequence, and is 12. The terminal device 3 generates a sequence r (αp) u,v (n) in the same manner as PUCCH in FIG. 6. That is, the terminal device 3 may generate the sequence r (αp) u,v (n) based on at least the physical layer cell identity. Further, the terminal device 3 multiplies the sequence r (αp) u,v (n) by 1 / √P, w’ (p) (m), and z(m) to generate a sequence r (p) PUCCH (*). w’ (p) (m) is an orthogonal sequence for DMRS. z(m) is always 1 for the DMRS of PUCCH used only for HARQ-ACK transmission. That is, when generating the DMRS of PUCCH used only for HARQ-ACK transmission, the process of multiplying by z(m) may not be performed. The terminal device 31 places the sequence r (p) PUCCH (*) in the SC-FDMA symbols of {2, 3, 4} in the first slot in the subframe, and then places it in {2, 3, 4} in the second slot. In a single SC-FDMA symbol, r (p) PUCCH(*) are arranged in order from sub - carriers with smaller numbers. Further, in the DMRS corresponding to a single PUCCH resource, w’(i) is one of [1 1 1], [1 e j2π / 3 e j4π / 3 ], and [1 e j4π / 3 e j2π / 3 ]. PUCCH can be used by the terminal device 3 to transmit an acknowledgment response for received downlink data when the downlink sub - frame is allocated. For example, PUCCH may be used to transmit an acknowledgment response for PDSCH (DL - SCH, downlink data). Also, PUCCH can be used by the terminal device 3 to perform an acknowledgment response for received downlink data when the sTTI of the downlink is allocated. For example, PUCCH may be used to transmit an acknowledgment response for sPDSCH (DL - SCH, downlink data). FIG. 7 is a diagram showing an example of the configuration of PUCCH for performing an acknowledgment response for received downlink data allocated to sTTI. For example, a reference signal (DMRS) for demodulation is allocated to the OS indicated by hatching, and a signal for acknowledgment response is allocated to the OS indicated by the grid. Thus, the channel for performing an acknowledgment response for received downlink data allocated to sTTI may be composed of sTTI. Here, the channel for performing an acknowledgment response for downlink data composed of sTTI is also referred to as sPUCCH. That is, sPUCCH may be used to transmit an acknowledgment response for downlink data in sTTI. FIG. 7 shows an example in which sPUCCH is composed of 2 - symbol TTI, but the sPUCCH according to this embodiment is not limited to this example and may be composed of any sTTI. The Physical Downlink Shared Channel (PDSCH; Physical Downlink Shared Channel) is used not only for downlink data but also to notify the terminal device 3 of responses to random access (random access response, RAR), paging, and system information that is not notified by the Physical Broadcast Information Channel as a layer 3 message. The radio resource allocation information of the Physical Downlink Shared Channel is indicated by the Physical Downlink Control Channel. The Physical Downlink Shared Channel is transmitted by being arranged in OFDM symbols other than the OFDM symbols in which the Physical Downlink Control Channel is transmitted. That is, the Physical Downlink Shared Channel and the Physical Downlink Control Channel are time-division multiplexed within one subframe. The PDSCH may be configured by sTTI. The PDSCH configured by sTTI is also referred to as sPDSCH. The Physical Uplink Shared Channel (PUSCH; Physical Uplink Shared Channel) mainly transmits uplink data and uplink control information, and it is also possible to include uplink control information such as CSI and ACK / NACK. In addition, it is also used to notify the base station device 1 from the terminal device 3 of layer 2 messages and layer 3 messages, which are upper layer control information, in addition to uplink data. Also, similar to the downlink, the radio resource allocation information of the Physical Uplink Shared Channel is indicated by the Physical Downlink Control Channel. The PUSCH may be configured by sTTI. The PUSCH configured by sTTI is also referred to as sPUSCH. The uplink reference signal (also referred to as uplink reference signal, Uplink Reference Signal, uplink pilot signal, or uplink pilot channel) includes a demodulation reference signal (DMRS; Demodulation Reference Signal) used by the base station apparatus 1 to demodulate the physical uplink control channel PUCCH and / or the physical uplink shared channel PUSCH, and a sounding reference signal (SRS; Sounding Reference Signal) mainly used by the base station apparatus 1 to estimate the uplink channel state. The sounding reference signal includes a periodic sounding reference signal (Periodic SRS) transmitted periodically and an aperiodic sounding reference signal (Aperiodic SRS) transmitted when instructed by the base station apparatus 1. The physical random access channel (PRACH; Physical Random Access Channel) is a channel used to notify (configure) a preamble sequence and has a guard time. The preamble sequence is configured to notify information to the base station apparatus 1 by a plurality of sequences. For example, when 64 types of sequences are prepared, 6-bit information can be indicated to the base station apparatus 1. The physical random access channel is used as an access means for the terminal device 3 to access the base station apparatus 1. In addition, the terminal device 3 and the base station apparatus 1 may apply a technique of aggregating (aggregating) frequencies (component carriers or frequency bands) of a plurality of different frequency bands into one frequency (frequency band) by carrier aggregation. The component carriers include an uplink component carrier corresponding to the uplink and a downlink component carrier corresponding to the downlink. In this specification, frequency and frequency band may be used synonymously. For example, when five component carriers with a frequency bandwidth of 20 MHz are aggregated by carrier aggregation, the terminal device 3 having the ability to perform carrier aggregation regards these as a frequency bandwidth of 100 MHz and performs transmission and reception. Note that the component carriers to be aggregated may be continuous frequencies or all or some of them may be discontinuous frequencies. For example, when the available frequency bands are the 800 MHz band, the 2 GHz band, and the 3.5 GHz band, one component carrier may be transmitted in the 800 MHz band, another component carrier may be transmitted in the 2 GHz band, and yet another component carrier may be transmitted in the 3.5 GHz band. It is also possible to aggregate a plurality of continuous or discontinuous component carriers in the same frequency band. The frequency bandwidth of each component carrier may be a frequency bandwidth (for example, 5 MHz or 10 MHz) narrower than the receivable frequency bandwidth (for example, 20 MHz) of the terminal device 3, and the aggregated frequency bandwidths may be different from each other. Although it is desirable that the frequency bandwidth is equal to any of the frequency bandwidths of the conventional cells in consideration of backward compatibility, a frequency bandwidth different from the frequency band of the conventional cells may also be used. It is also possible to aggregate component carriers (carrier types) without backward compatibility. Note that it is desirable that the number of uplink component carriers assigned (set, added) by the base station device 1 to the terminal device 3 is the same as or less than the number of downlink component carriers. A cell composed of an uplink component carrier for which an uplink control channel for wireless resource request is set and a downlink component carrier that is cell-specifically connected to the uplink component carrier is called a primary cell (PCell: Primary cell). A cell composed of component carriers other than the primary cell is called a secondary cell (SCell: Secondary cell). The terminal device 3 performs reception of paging messages, detection of update of notification information, initial access procedures, setting of security information, etc. in the primary cell, while it may not perform these in the secondary cell. The primary cell is not subject to activation and deactivation control (i.e., it is always considered to be activated), while the secondary cell has states of activation and deactivation, and the change of these states is explicitly specified by the base station apparatus 1 and is also changed based on a timer set in the terminal apparatus 3 for each component carrier. The primary cell and the secondary cell together are referred to as a serving cell (in - range cell). Note that carrier aggregation is communication using a plurality of cells with a plurality of component carriers (frequency bands), and is also referred to as cell aggregation. Note that the terminal apparatus 3 may be wirelessly connected to the base station apparatus 1 via a relay station apparatus (or a repeater) for each frequency. That is, the base station apparatus 1 of the present embodiment can be replaced with a relay station apparatus. The base station apparatus 1 manages cells, which are areas where the terminal apparatus 3 can communicate with the base station apparatus 1, for each frequency. One base station apparatus 1 may manage a plurality of cells. Cells are classified into a plurality of types according to the size of the area (cell size) where communication with the terminal apparatus 3 is possible. For example, cells are classified into macro cells and small cells. Further, small cells are classified into femto cells, pico cells, and nano cells according to the size of their areas. Also, when the terminal apparatus 3 can communicate with a certain base station apparatus 1, among the cells of that base station apparatus 1, the cell set to be used for communication with the terminal apparatus 3 is a serving cell, and the other cells not used for communication are referred to as neighboring cells. In other words, in carrier aggregation (also referred to as carrier aggregation), the set plurality of serving cells include one primary cell and one or more secondary cells. The primary cell is the serving cell where the initial connection establishment procedure has been performed, the serving cell where the connection reconstruction procedure has been initiated, or the cell designated as the primary cell in the handover procedure. The primary cell operates at the primary frequency. A secondary cell may be configured when the connection is (re)established or thereafter. The secondary cell operates at the secondary frequency. Note that the connection may be referred to as an RRC connection. For a terminal device 3 supporting CA, it is aggregated by one primary cell and one or more secondary cells. Hereinafter, the basic structure (architecture) of dual connectivity will be described. For example, a case where the terminal device 3 is simultaneously connected to a plurality of base station devices 1 (for example, base station device 1-1, base station device 1-2) will be described. Assume that the base station device 1-1 is a base station device constituting a macro cell, and the base station device 1-2 is a base station device constituting a small cell. In this way, the simultaneous connection of the terminal device 3 using a plurality of cells belonging to a plurality of base station devices 1 is referred to as dual connectivity. The cells belonging to each base station device 1 may be operated at the same frequency or at different frequencies. Note that carrier aggregation differs from dual connectivity in that a single base station device 1 manages a plurality of cells and the frequencies of the respective cells are different. In other words, carrier aggregation is a technique for connecting a single terminal device 3 and a single base station device 1 via a plurality of cells having different frequencies, whereas dual connectivity is a technique for connecting a single terminal device 3 and a plurality of base station devices 1 via a plurality of cells having the same or different frequencies. The techniques applicable to carrier aggregation can be applied by the terminal device 3 and the base station device 1 to the cells connected by dual connectivity. For example, the terminal device 3 and the base station device 1 may apply techniques such as allocation and activation / deactivation of the primary cell and secondary cells to the cells connected by dual connectivity. Next, the transmission power control for transmission on PUCCH in this embodiment will be described. When the terminal device 3 performs transmission on PUCCH, it sets the transmission power value for transmission on PUCCH in a certain subframe i for a certain cell c based on Equation (1). P in Equation (1) ｒｅａｌ_ＰＵＣＣＨ，ｃ (i) is defined based on Equation (2). Here, P ｒｅａｌ_ＰＵＣＣＨ，ｃ (i) is a power value calculated (estimated) based on a real transmission on PUCCH. Also, calculating (estimating) a power value based on a real transmission on PUCCH means calculating (estimating) a power value based on an actual transmission on PUCCH. Here, P ＰＵＣＣＨ，ｃ (i) indicates the transmission power value for transmission on PUCCH in the i-th subframe. P ０_ＰＵＣＣＨ，ｃ is a parameter indicating the basic transmission power for transmission on PUCCH and is instructed from the upper layer. P ０_ＰＵＣＣＨ，ｃ is P ０_ＮＯＭＩＮＡＬ_ＰＵＣＣＨ、ｃ and P ０_ＵＥ_ＰＵＣＣＨ、ｃ is composed of. P ０_ＮＯＭＩＮＡＬ_ＰＵＣＣＨ、ｃ and P ０_ＵＥ_ＰＵＣＣＨ、ｃ are each supported from the upper layer. Here, P ０_ＮＯＭＩＮＡＬ_ＰＵＣＣＨ、ｃ and P ０_ＵＥ_ＰＵＣＣＨ、ｃ may be determined based on the PUCCH format (which may also be a method of configuring (s) PUCCH). Also, P ０_ＮＯＭＩＮＡＬ_ＰＵＣＣＨ、ｃ and P ０_ＵＥ_ＰＵＣＣＨ、ｃ may be determined based on the number of bits of the transmitted scheduling request. h(n ＣＱＩ、 n ＨＡＲＱ ) is a value calculated based on the number of bits transmitted on PUCCH and the PUCCH format. That is, based on the PUCCH format (which may also be a method of configuring (s) PUCCH), h(n ＣＱＩ、 n ＨＡＲＱ ) may be determined. Here, n ＣＱＩindicates the number of bits of the channel state information transmitted by PUCCH, and n ＨＡＲＱ indicates the number of bits of HARQ-ACK transmitted by PUCCH. Here, h(n ＣＱＩ、 n ＨＡＲＱ ) may include the number of bits of the scheduling request transmitted by PUCCH. That is, in Equation (2), h(n ＣＱＩ、 n ＨＡＲＱ ) may be replaced by h(n ＣＱＩ、 n ＨＡＲＱ , n ＳＲ ). Note that n ＳＲ may be related to the number of bits of the scheduling request to be transmitted. For example, h(n ＣＱＩ、 n ＨＡＲＱ , 1) = X ＳＲ , h(n ＣＱＩ、 n ＨＡＲＱ , 0) = X ０ may be. X ＳＲ , and X ０ are the values of h(n ＣＱＩ、 n ＨＡＲＱ , n ＳＲ ) when a 1-bit scheduling request is transmitted and when no scheduling request is transmitted, respectively. For example, X ＳＲ = 0, X ０ = 10 * Log １０ (2). X ＳＲ and S ０ may be determined based on n ＣＱＩ and n ＨＡＲＱ . Δ Ｆ_ＰＵＣＣＨ (F) is an offset value indicated by the upper layer for each format of PUCCH. That is, an offset value may be indicated for each PUCCH format ((s)PUCCH may also be a configuration method). For example, Δ Ｆ_ＰＵＣＣＨ (F) for PUCCH format 1a is always 0. For example, for (s)PUCCH, when a scheduling request is transmitted, Δ Ｆ_ＰＵＣＣＨ (F) = 0, and when no scheduling request is transmitted, Δ Ｆ_ＰＵＣＣＨ (F) = 10 * Log １０ (2) may be. The terminal device 3 may set the value of g(i) based on the mathematical formula (3). Here, δ ＰＵＣＣＨ is a correction value and is called a TPC command. That is, δ ＰＵＣＣＨ (i - K ＰＵＣＣＨ ) indicates the value accumulated in g(i - 1). Also, δ ＰＵＣＣＨ (i - K ＰＵＣＣＨ ) is instructed based on the value set in the field of the TPC command for PUCCH included in the downlink grant for a certain cell and DCI format 3 / 3A for PUCCH received in a certain subframe (i - K ＰＵＣＣＨ ). For example, the values set in the field of the TPC command for PUCCH included in the downlink grant and DCI format 3 for PUCCH (a 2-bit information field) are mapped to the accumulated correction values {-1, 0, 1, 3}. For example, the values set in the field of the TPC command for PUCCH included in DCI format 3A for PUCCH (a 1-bit information field) are mapped to the accumulated correction values {-1, 1}. The value of K ＰＵＣＣＨ is, for example, 4. The value of KPUCCH may be determined based on the (s)TTI length of PUCCH or the (s)TTI length of the PDSCH corresponding to the reception confirmation response included in sPUCCH. An example (configuration method 1) of the configuration method of sPUCCH according to this embodiment is a sequence determined based on the mathematical formula (4). Here, S １ is the sequence of sPUCCH, and α １ and α ２ are cyclic shifts respectively. Here, the configuration method of the sequence S １ of sPUCCH is also referred to as configuration method 1. Note that hereinafter, the sequence r’ u,v (n) is also referred to as r(n). Also, the sequence based on α1 (the first term on the right side in the mathematical formula (4)) is also referred to as a reference signal sequence. Also, α ２The series based on this (the second term on the right side of Equation (4)) is also referred to as the data series. Also, the first term on the right side of Equation (4) is the first (or second) series, and α １ is also referred to as the first (or second) cyclic shift. Also, the second term on the right side of Equation (4) is the second (or first) series, and α ２ is also referred to as the second (or first) cyclic shift. Here, Configuration Method 1 is a method in which a plurality of series multiplied (applied) by different cyclic shifts are included within one SC-FMDA symbol. The sPUCCH series S transmitted by the terminal device 3 １ can be received by the base station device 1. For example, the base station device 1 performs correlation processing on the received sPUCCH series S １ using r(n), thereby detecting the cyclic shifts α １ and α ２ . Next, the base station device 1 can estimate d(0) by detecting the phase difference, etc. of the series to which different cyclic shifts α １ and α ２ are applied. sPUCCH may be used at least to transmit SR, an acknowledgment response (also referred to as ACK / NACK, A / N, etc.). That is, the information transmitted using sPUCCH is at least only SR, only A / N, and information indicating SR + A / N (SR and A / N) (hereinafter, information including only SR, only A / N, and information indicating SR + A / N is also referred to as uplink control information). The value of the cyclic shift α １ and / or α ２ may be related to SR. That is, when α １ and / or α ２ indicates a specific value, the base station device 1 may interpret that SR has been transmitted. That is, based on the values of α １ and / or α ２ , it may be indicated which of positive SR and negative SR has been transmitted. Also, the cyclic shifts α １ and α ２The difference and SR may be related. That is, α １ and / α ２ When the difference indicates a specific value, the base station device 1 may interpret that SR has been transmitted. That is, α １ and / or α ２ Based on the difference, it may be indicated which of the positive SR and the negative SR has been transmitted. The value of d(0) and SR may be related. That is, when d(0) indicates a specific value (modulation symbol value, bit sequence, etc.), the base station device 1 may interpret that SR has been transmitted. That is, based on the value of d(0), it may be indicated which of the positive SR and the negative SR has been transmitted. Cyclic shift α １ and / or α ２ The value of and A / N may be related. That is, α １ and / or α ２ When indicates a specific value, the base station device 1 may interpret that A / N has been transmitted. Also, cyclic shift α １ and α ２ The difference between and A / N may be related. That is, α １ and / or α ２ Based on the value of, it may be indicated which of ACK and NACK has been transmitted. That is, α １ and / α ２ When the difference indicates a specific value, the base station device 1 may interpret that A / N has been transmitted. That is, α １ and / or α ２ Based on the difference, it may be indicated which of ACK and NACK has been transmitted. The value of d(0) and A / N may be related. That is, when d(0) indicates a specific value (modulation symbol value, bit sequence, etc.), the base station device 1 may interpret that A / N has been transmitted. That is, based on the value of d(0), it may be indicated which of ACK and NACK has been transmitted. Here, α １ The value of, α ２ The value of, the value of d(0), and SR may be related. That is, α １ , α ２When d(0) indicates a specific value, the base station apparatus 1 may interpret that an SR has been transmitted. That is, α １ α ２ Based on α and d(0), it may be indicated which of the positive SR and the negative SR has been transmitted. Here, α １ The value of α ２ The value of α, the value of d(0), and A / N may be related. That is, α １ α ２ When d(0) indicates a specific value, the base station apparatus 1 may interpret that an A / N has been transmitted. That is, α １ α ２ Based on α and d(0), it may be indicated which of ACK and NACK has been transmitted. Here, in Configuration Method 1, an appropriate cyclic shift can be assigned to each of the uplink control information. That is, an appropriate cyclic shift can be assigned to each of SR only, A / N only, and SR + A / N. In an example of the method for assigning a cyclic shift to the uplink control information in sPUCCH based on Configuration Method 1 (hereinafter, Assignment Method 1), when only SR is transmitted (α １ α ２ ), = (α Ａ α Ｂ ) may be satisfied. Also, when only A / N is transmitted (α １ α ２ ), = (α Ａ α Ｃ ) may be satisfied. Also, when SR + A / N is transmitted (α １ α ２ ), = (α Ｂ α Ｃ ) may be satisfied. Here, α Ａ α Ｂ And α Ｃ May indicate different cyclic shift amounts. That is, α １ When only SR is transmitted, and α １ When only A / N is transmitted, as the same cyclic shift amount (α Ａmay be used. Also, α when only SR is transmitted ２ and α when SR + A / N is transmitted １ may use the same cyclic shift amount (α Ｂ ). Also, α when only A / N is transmitted ２ and α when SR + A / N is transmitted ２ may use the same cyclic shift amount (α Ｃ ). Also, in another example of the method for allocating cyclic shift to uplink control information in sPUCCH based on Configuration Method 1 (hereinafter referred to as Allocation Method 2), when only SR is transmitted, (α １ , α ２ ) = (α Ａ , α Ａ ) may be used. Also, when only A / N is transmitted, (α １ , α ２ ) = (α Ａ , α Ｃ ) may be used. Also, when SR + A / N is transmitted, (α １ , α ２ ) = (α Ａ , α Ｃ ) may be used. That is, in sPUCCH that transmits only SR, since d(0) in Equation (4) is not used, α １ = α ２ = α Ａ is used, and simplification of the configuration of the terminal device 3 or the base station device 1, improvement of transmission efficiency or detection performance, etc. are expected. That is, when only SR is transmitted, α １ and α ２ may use the same cyclic shift amount (α Ａ ). Also, α １ (α ２ ) when only SR is transmitted and α １ when only A / N is transmitted may use the same cyclic shift amount (α Ａ ). Also, α １ (α ２), and α when SR + A / N is transmitted １ as the same cyclic shift amount (α Ａ ) may be used. Also, α when only A / N is transmitted ２ and α when SR + A / N is transmitted ２ as the same cyclic shift amount (α Ｃ ) may be used. Here, when the allocation method 2 is applied to the terminal device 3, the power allocated to the reference signal sequence when only SR is transmitted is twice that when at least A / N is transmitted. Here, the case where at least A / N is transmitted may include the case where only A / N is transmitted and / or the case where SR + A / N is transmitted. This is because α １ = α ２ and it is caused by the second term on the right side being added to the first term on the right side. Therefore, the base station device 1 is required to change the power expected to be received between the case where only SR transmission is expected and the case where at least A / N transmission is expected. Also, when the base station device 1 expects to receive SR + A / N, if the terminal device 3 does not transmit A / N, the power allocated to the reference signal sequence is twice that when the terminal device 3 transmits A / N. The terminal device 3 can change the transmission power between the case where only SR is transmitted and the case where at least A / N is transmitted. That is, the terminal device 3 can change the transmission power according to the allocated cyclic shift. For example, the terminal device 3 can set the transmission power when only SR is transmitted to X times the transmission power when at least A / N is transmitted. For example, X is 2. That is, the terminal device 3 can change the transmission power based on different values of X according to the type of uplink control information transmitted. The terminal device 3 may apply different transmission power controls depending on whether only the SR is transmitted or at least the A / N is transmitted. That is, the terminal device 3 may apply different transmission power controls according to the assigned cyclic shift. For example, the transmission power control applied when at least the A / N is transmitted may be based on Equations (1) and (2), and the transmission power control applied when only the SR is transmitted may be a method not based on Equations (1) and (2). For example, the transmission power control applied when only the SR is transmitted may also be based on Equation (5). In Equation (5), a new offset parameter X is introduced for Equation (2). ２ For example, the offset parameter X ２ is 0 when applied in the case where at least the A / N is transmitted, and may be -10 * Log １０ (2) when applied in the case where only the SR is transmitted. That is, the offset parameter may vary based on the type of uplink control information transmitted. Also, the equation used for the transmission power control applied by the terminal device during sPUCCH transmission may vary according to the uplink control information transmitted. The terminal device 3 may use different parameters for transmission power control depending on whether only the SR is transmitted or at least the A / N is transmitted. That is, the terminal device 3 may apply different transmission power control information according to the assigned cyclic shift. Here, for example, the transmission power control information may include P ｃ＿ｍａｘ，ｃ , PL ｃ , h(n ＣＱＩ , n ＨＡＲＱ ), n ＣＱＩ , n ＨＡＲＱ , Δ Ｆ＿ＰＵＣＣＨ (F), g(i), δ ＰＵＣＣＨ , and / or K ＰＵＣＣＨ . That is, the terminal device 3 can perform transmission power control of sPUCCH based on the transmission power control information. The terminal device 3 can apply different transmission power controls based on the number of SC-FDMA symbols that constitute (s)PUCCH. For example, when the number of SC-FDMA symbols that constitute (s)PUCCH in the terminal device 3 is N ｓＰＵＣＣＨ in the following cases, different transmission power controls are applied to (s)PUCCH according to the uplink control information, and when the number of SC-FDMA symbols that constitute (s)PUCCH is N ｓＰＵＣＣＨ is greater, regardless of the uplink control information, transmission power control based on Formula (1) and Formula (2) may be applied to (s)PUCCH. Also, in another example, the terminal device 3 may apply transmission power control based on a function or table that associates the number N ｓＰＵＣＣＨ of SC-FDMA symbols that constitute (s)PUCCH with the transmission power. The terminal device 3 can apply different transmission power controls based on the bandwidth of (s)PUCCH. For example, when the bandwidth of (s)PUCCH in the terminal device 3 is W ｓＰＵＣＣＨ in the following cases, different transmission power controls are applied to (s)PUCCH according to the uplink control information, and when the bandwidth of (s)PUCCH is W ｓＰＵＣＣＨ is greater, regardless of the uplink control information, transmission power control based on Formula (1) and Formula (2) may be applied to (s)PUCCH. Also, in another example, the terminal device 3 may apply transmission power control based on a function or table that associates the bandwidth W ｓＰＵＣＣＨ of (s)PUCCH with the transmission power. For example, the base station device 1 may transmit (configure) the transmission power control information (parameters, indexes, tables, formulas, calculation methods, etc.) used in each of the cases where only SR is transmitted by the terminal device 3 and the case where at least A / N is transmitted, using upper layer signaling (RRC signaling), downlink control information (DCI), PDCCH, and / or PDSCH, etc. Subsequently, the relationship of the cyclic shifts α Ａ , α Ｂ , α Ｃ will be described. FIG. 8 shows the α of sPUCCH based on Allocation Method 1 or Allocation Method 2 Ａ , αＢ 、 α Ｃ This is a diagram showing an example of the relationship (cyclic shift relationship 1) of α. In sPUCCH based on allocation method 2, when only SR is transmitted, α Ｂ may be considered not to be given. In the example shown in FIG. 8, the cyclic shift α when each of the uplink control information is transmitted Ａ 、 α Ｂ 、 α Ｃ does not change. Therefore, advantages such as ease of implementation are also expected. On the other hand, when at least A / N is transmitted, the frequency domain interval between the two cyclic shifts is 2*N ｄ and the detection accuracy of the base station apparatus 1 becomes an issue. Here, N ｄ is the unit of cyclic shift, and for example, the phase rotation amount (such as 2π / 12 may be used). That is, the cyclic shift may be a phase rotation in the time direction (or frequency direction). FIG. 9 is a diagram showing another example of the relationship (cyclic shift relationship 2) of α, α, α of sPUCCH based on allocation method 1 or allocation method 2. The cyclic shift relationship 2 is α, α, α according to the uplink control information expected by the base station apparatus 1 Ａ 、 α Ｂ 、 α Ｃ This is an example where the values (and relationships) are different. Thus, when only A / N transmission is expected, the frequency domain interval between the two cyclic shifts α, α Ａ 、 α Ｂ 、 α Ｃ is 5*N, and when SR+A / N transmission is expected, the frequency domain interval between each cyclic shift α, α, α Ａ 、 α Ｂ is 3*N, and an improvement in the detection accuracy of the base station apparatus 1 is expected. That is, for example, α, α, α ｄ is when only SR transmission is expected and / or when only A / N transmission is expected, α Ａ 、 α Ｂ 、 α Ｃ is 3*N, and an improvement in the detection accuracy of the base station apparatus 1 is expected. That is, for example, α, α, α ｄ are such that when only SR transmission is expected and / or when only A / N transmission is expected, α Ａ 、 α Ｂ 、 α Ｃ =α Ｂ =α Ａ +Δ１ With the relationship, when SR + A / N transmission is expected, α Ｃ = 2 * Δ ２ + α Ａ = Δ ２ + α Ｂ may have the relationship. Δ １ is, α Ａ and α Ｂ may be set so that the interval (or difference) between them is maximized. Also, Δ ２ is, α Ａ , α Ｂ and α Ｃ may be set so that the interval (or difference) between them is maximized. Also, for example, α Ａ , α Ｂ , α Ｃ is, when SR + A / N transmission is expected, α Ｃ = Δ ２Ｂ + α Ｂ , α Ｂ = Δ ２Ａ + α ２Ａ may have the relationship. Here, Δ ２Ｂ is, α Ｂ and α Ｃ may be set so that the interval (or difference) between them is maximized. Also, here, Δ ２Ａ is, α Ａ and α Ｂ may be set so that the interval (or difference) between them is maximized. That is, the terminal device 3 can change the cyclic shift related to the sPUCCH configuration according to the type of uplink control information, subframe number, sTTI number, sTTI length, etc. expected to be transmitted by the base station device 1. Note that the CS control information (value, or value setting method, or parameters for value calculation, etc.) for the cyclic shift related to the sPUCCH configuration may be based on the upper layer signaling (RRC signaling), downlink control information (DCI), (s)PDCCH, and / or (s)PDSCH, etc. transmitted by the base station device 1. Here, the CS control information may be information related to part or all of α １ , α ２ , α Ａ , α Ｂ , α Ｃ . Note that the relationship of the cyclic shift does not necessarily have to be based on the interval in the frequency domain. For example, from the perspective of the terminal device 3, the sequence S generated based on the mathematical formula (4) １ The relationship of the cyclic shift or α can be based on the characteristics of (for example, PAPR (Peak to Average Power Ratio), CM (Cubic Metric), etc.) Ａ α Ｂ α Ｃ The value of α may be set. Also, the characteristics of the sequence S1 may be values calculated by computer simulation or the like, and the relationship of the cyclic shift or α Ａ α Ｂ α Ｃ The value of α may be based on computer simulation (also referred to as a sequence generated by a computer or a CGS (Computer Generated Sequence), etc.). An example of the method for allocating the cyclic shift to the uplink control information in the sPUCCH based on Configuration Method 1 (hereinafter, Allocation Method 3) is that (α １ α ２ ) = (α Ａ α Ｂ ), and the resource index (an index that specifies resources such as frequency, time, space) is different between the case where the transmission of SR is expected and the case where the transmission of A / N is expected. For example, the RBs used for the transmission of sPUCCH can be different between the case where the transmission of SR is expected and the case where the transmission of A / N is expected. Further, when the transmission of SR + A / N is expected, for example, the resource index can be different between at least the case where SR is transmitted and the case where only A / N is transmitted. Another example (Configuration Method 2) of the configuration method of the sPUCCH according to the present embodiment can be determined based on the mathematical formula (6). In Configuration Method 2, a sequence with a cyclic shift applied is arranged alone within one SC-FMDA symbol. That is, Configuration Method 2 may be a method in which one sequence multiplied (applied) by a cyclic shift is included within one SC-FMDA symbol. The sPUCCH sequence S transmitted by the terminal device 3 ２ can be received by the base station device 1. For example, the base station device 1 can detect the cyclic shift α by performing correlation processing on the received sPUCCH sequence S ２ using r(n). As shown in the hatched portion of FIG. 10, in Configuration Method 2, sequences can be assigned in a comb (interlace) pattern within one SC-FDMA symbol. For example, as shown in FIG. 10, when sequences are assigned in a comb pattern, two assignment patterns can be generated. Here, Assignment Pattern 1 in FIG. 10 is also referred to as Assignment Pattern X1. Also, Assignment Pattern 2 in FIG. 10 is also referred to as Assignment Pattern X2. Note that Configuration Method 2 is not limited to the example of FIG. 10, and two or more assignment patterns may be generated by providing two or more intervals in a comb pattern. Note that Configuration Method 2 may be based on an equation other than Equation (5), for example, the same method as the SRS generation method. Hereinafter, in Configuration Method 2, sPUCCH configured by an example shown in FIG. 10 will be taken as an example for explanation. Also, in the method shown in Configuration Method 2, sPUCCH may be configured by a combined sequence of sequences with the same or different cyclic shifts applied to each assignment pattern. Cyclic shifts α １ ２ and α ２ ２ set for Assignment Patterns X1 and X2 for uplink control information in sPUCCH based on Configuration Method 2 １ ２ In an example (hereinafter, Assignment Method 4), for example, when only SR is transmitted, (α ２ ２ ) = (α Ａ , null) may be used. Also, when only A / N is transmitted, (α１ ２ and α ２ ２ ) = (α Ａ and α Ｂ ) may also be used. Also, when SR + A / N is transmitted, (α １ ２ and α ２ ２ ) = (α Ａ and α Ｃ ) may be used. That is, α when only SR is transmitted １ ２ and α when only A / N is transmitted １ ２ and α when only A / N is transmitted １ ２ As such, the same cyclic shift amount (α Ａ ) may be used. Here, null may indicate that no cyclic shift is assigned and no sequence is generated. When only SR is transmitted, (α １ ２ and α ２ ２ ) = (α Ａ and α Ａ ) may be set. Also, when only SR is transmitted, (α １ ２ and α ２ ２ ) = (α Ａ and α Ｄ ) may be set. Hereinafter, the sequence generated based on formula (5) or other formula (or law) used for the allocation pattern X1 is also referred to as the first (or second) sequence, and the cyclic shift α １ applied to the first sequence is also referred to as the first (or second) cyclic shift. Also, the sequence generated based on formula (5) or other formula (or law) used for the allocation pattern X2 is also referred to as the second (or first) sequence, and the cyclic shift α ２ applied to the second sequence is also referred to as the second (or first) cyclic shift. Here, when the allocation method 4 is applied to the terminal device 3, the power per allocation pattern (allocated power) becomes twice when only the SR is transmitted as compared with the case where at least the A / N is transmitted. This is because the allocation pattern 2 cannot be allocated in the case of only the SR. Therefore, the base station device 1 is required to change the power for expecting reception between the case where only the transmission of the SR is expected and the case where at least the transmission of the A / N is expected. Further, when the base station device 1 expects to receive the SR + A / N, when the terminal device 3 does not transmit the A / N, the power allocated to the reference signal sequence becomes twice as compared with the case where the terminal device 3 transmits the A / N. When the allocation method 4 is applied, the terminal device 3 may determine the transmission power using the same method as in the case where the allocation method 2 is applied. The configuration method 1 and the configuration method 2 can be configured with 1 SC-FDMA symbol. Further, the sequence generated based on the configuration method 1 or the configuration method 2 may be applied with frequency hopping or the like that maps the same sequence to different frequency bands. Here, the sequence to which frequency hopping is applied does not necessarily have to be exactly the same sequence. For example, frequency hopping may be applied to different sequences including the same information. FIG. 11 is a schematic diagram showing an example of the block configuration of the base station device 1 according to the present embodiment. The base station device 1 includes an upper layer (upper layer control information notification unit, upper layer processing unit) 301, a control unit (base station control unit) 302, a codeword generation unit 303, a downlink subframe generation unit 304, an OFDM signal transmission unit (downlink transmission unit) 306, a transmission antenna (base station transmission antenna) 307, a reception antenna (base station reception antenna) 308, an SC-FDMA signal reception unit (CSI reception unit) 309, and an uplink subframe processing unit 310. The downlink subframe generation unit 304 includes a downlink reference signal generation unit 305. Further, the uplink subframe processing unit 310 includes an uplink control information extraction unit (CSI acquisition unit) 311. FIG. 12 is a schematic diagram showing an example of the block configuration of the terminal device 3 according to the present embodiment. The terminal device 3 includes a reception antenna (terminal reception antenna) 401, an OFDM signal reception unit (downlink reception unit) 402, a downlink subframe processing unit 403, a transport block extraction unit (data extraction unit) 405, a control unit (terminal control unit) 406, an upper layer (upper layer control information acquisition unit, upper layer processing unit) 407, a channel state measurement unit (CSI generation unit) 408, an uplink subframe generation unit 409, an SC-FDMA signal transmission unit (UCI transmission unit) 411, and a transmission antenna (terminal transmission antenna) 412. The downlink subframe processing unit 403 includes a downlink reference signal extraction unit 404. Further, the uplink subframe generation unit 409 includes an uplink control information generation unit (UCI generation unit) 410. First, the flow of downlink data transmission and reception will be described with reference to FIGS. 11 and 12. In the base station apparatus 2, the control unit 302 holds an MCS (Modulation and Coding Scheme) indicating the modulation method and coding rate in the downlink, a downlink resource allocation indicating the RBs used for data transmission, and information used for HARQ control (redundancy version, HARQ process number, new data indicator), and controls the codeword generation unit 303 and the downlink subframe generation unit 304 based on these. The downlink data (also referred to as the downlink transport block) sent from the upper layer 301 is subjected to processing such as error correction coding and rate matching processing under the control of the control unit 302 in the codeword generation unit 303, and codewords are generated. In one subframe in one cell, a maximum of two codewords are transmitted simultaneously. In the downlink subframe generation unit 304, a downlink subframe is generated according to an instruction from the control unit 302. First, the codewords generated in the codeword generation unit 303 are converted into a modulation symbol sequence by modulation processing such as PSK (Phase Shift Keying) modulation or QAM (Quadrature Amplitude Modulation). Also, the modulation symbol sequence is mapped to the REs in some RBs, and a downlink subframe for each antenna port is generated by precoding processing. At this time, the transmission data sequence sent from the upper layer 301 includes upper layer control information, which is control information (for example, dedicated (individual) RRC (Radio Resource Control) signaling) in the upper layer. Also, in the downlink reference signal generation unit 305, a downlink reference signal is generated. The downlink subframe generation unit 304 maps the downlink reference signal to the REs in the downlink subframe according to an instruction from the control unit 302. The downlink subframe generated by the downlink subframe generation unit 304 is modulated into an OFDM signal in the OFDM signal transmission unit 306 and transmitted via the transmission antenna 307.Here, a configuration having one OFDM signal transmission unit 306 and one transmission antenna 307 is illustrated. However, when transmitting a downlink subframe using a plurality of antenna ports, a configuration having a plurality of OFDM signal transmission units 306 and transmission antennas 307 may be used. Further, the downlink subframe generation unit 304 may also have the ability to generate physical layer downlink control channels such as PDCCH and EPDCCH and map them to REs in the downlink subframe. A plurality of base station apparatuses (base station apparatus 1-1 and base station apparatus 1-2) each transmit an individual downlink subframe. In the terminal device 3, an OFDM signal is received by the OFDM signal receiving unit 402 via the reception antenna 401, and OFDM demodulation processing is performed. The downlink subframe processing unit 403 first detects physical layer downlink control channels such as PDCCH and EPDCCH. More specifically, the downlink subframe processing unit 403 decodes as if PDCCH and EPDCCH are transmitted in areas where PDCCH and EPDCCH can be allocated, and checks the CRC (Cyclic Redundancy Check) bits added in advance (blind decoding). That is, the downlink subframe processing unit 403 monitors PDCCH and EPDCCH. When the CRC bits match an ID (C-RNTI (Cell-Radio Network Temporary Identifier), SPS-C-RNTI (Semi Persistent Scheduling-C-RNTI), etc., a terminal-specific identifier allocated to one terminal device, or Temporaly C-RNTI) allocated in advance from the base station device, the downlink subframe processing unit 403 recognizes that PDCCH or EPDCCH has been detected, and extracts the PDSCH using the control information included in the detected PDCCH or EPDCCH. The control unit 406 holds an MCS indicating the modulation method and coding rate in the downlink based on the control information, a downlink resource allocation indicating the RBs used for downlink data transmission, and information used for HARQ control, and controls the downlink subframe processing unit 403, the transport block extraction unit 405, etc. based on these. More specifically, the control unit 406 controls to perform RE demapping processing, demodulation processing, etc. corresponding to the RE mapping processing and modulation processing in the downlink subframe generation unit 304. The PDSCH extracted from the received downlink subframe is sent to the transport block extraction unit 405. Also, the downlink reference signal extraction unit 404 in the downlink subframe processing unit 403 extracts the downlink reference signal from the downlink subframe.In the transport block extraction unit 405, rate matching processing in the codeword generation unit 303, rate matching processing corresponding to error correction coding, error correction decoding, etc. are performed, and a transport block is extracted and sent to the upper layer 407. The transport block contains upper layer control information, and the upper layer 407 notifies the control unit 406 of necessary physical layer parameters based on the upper layer control information. Note that a plurality of base station devices 1 (base station device 1-1 and base station device 1-2) each transmit an individual downlink subframe, and in the terminal device 3, in order to receive these, the above-described processing may be performed for each downlink subframe of each of the plurality of base station devices 1. At this time, the terminal device 3 may or may not recognize that a plurality of downlink subframes are being transmitted from a plurality of base station devices 2. If it does not recognize, the terminal device 3 may simply recognize that a plurality of downlink subframes are being transmitted in a plurality of cells. Also, the transport block extraction unit 405 determines whether or not a transport block has been correctly detected, and the determination result is sent to the control unit 406. Next, the flow of uplink signal transmission and reception will be described. In the terminal device 3, under the instruction of the control unit 406, the downlink reference signal extracted by the downlink reference signal extraction unit 404 is sent to the channel state measurement unit 408, where the channel state and / or interference is measured, and further, based on the measured channel state and / or interference, CSI is calculated. Also, based on the determination result of whether the transport block has been correctly detected or not, the control unit 406 instructs the uplink control information generation unit 410 to generate HARQ-ACK (DTX (not transmitted), ACK (detection successful) or NACK (detection failed)) and map it to the downlink subframe. The terminal device 3 performs these processes for each downlink subframe of a plurality of cells respectively. The uplink control information generation unit 410 generates a PUCCH including the calculated CSI and / or HARQ-ACK. The uplink subframe generation unit 409 maps the PUSCH including the uplink data sent from the upper layer 407 and the PUCCH generated by the uplink control information generation unit 410 to the RBs in the uplink subframe, and generates an uplink subframe. The uplink subframe is subjected to SC-FDMA modulation in the SC-FDMA signal transmission unit 411 to generate an SC-FDMA signal, which is transmitted via the transmission antenna 412. Also, in each of the above embodiments, terms such as primary cell and PS cell have been used for description, but it is not necessarily required to use these terms. For example, the primary cell in each of the above embodiments can also be called a master cell, and the PS cell in each of the above embodiments can also be called a primary cell.
