This application claims priority under JP 2017-238477, filed December 13, 2017, the contents of which are incorporated herein by reference.

Prerequisites for the creation of the invention

[0002]

The 3rd Generation Partnership Project (3GPP) considered a radio access scheme and a radio network for cellular mobile communications (hereinafter referred to as "Long Term Evolution (LTE)" or "Enhanced Universal Terrestrial Radio Access (EUTRA) network"). In the LTE standard, the base station device is also called an evolved Node B (eNodeB), and the terminal device is also called user equipment (UE). LTE is a cellular communication system in which a plurality of areas are arranged in a cellular structure, each of the plurality of areas falling within the coverage area of base station devices. One base station device can manage multiple cells.

[0003]

According to the LTE standard (version 13), uplink control information (NPLs 1, 2, 3, and 4) is transmitted using the PUSCH and PUCCH channels. The 3GPP project has explored tools that enhance the technical capabilities of delay reduction. In NPL 5, discussion began on reducing processing time for 1 ms transmission time interval (TTI).

Description of Embodiments

[0011]

Embodiments of the present invention will be described below.

[0012]

FIG. 1 is a conceptual diagram of a radio communication system according to the present embodiment. As shown in FIG. 1, the radio communication system includes terminal apparatuses 1A to 1C and a base station apparatus 3. Terminal devices 1A-1C are called terminal devices 1.

[0013]

The following describes carrier aggregation.

[0014]

According to the present embodiment, the terminal apparatus 1 is configured with two serving cells. The method in which the terminal apparatus 1 communicates through a plurality of serving cells is called cell aggregation or carrier aggregation. Two serving cells include one primary cell. Two serving cells include one secondary cell. The primary cell is the serving cell in which the initial connection setup procedure has been performed, the serving cell in which the connection recovery procedure has been started, or the cell designated as the primary cell in the handover procedure. The secondary cell may be configured at or after the radio resource control (RRC) connection is established. In the present embodiment, frequency division duplexing (FDD) may be applied to the primary cell. Time division duplexing (TDD) may be applied to the secondary cell.

[0015]

The carrier corresponding to the serving cell in the downlink is referred to as the downlink component carrier. The carrier corresponding to the serving cell in the uplink is called the uplink component carrier. The downlink carrier component and the uplink carrier component are collectively referred to as carrier components.

[0016]

The terminal device 1 may simultaneously transmit and/or receive on a plurality of physical channels in a plurality of serving cells (carriers). Transmission on one physical channel is carried out in one serving cell (carrier component) from a plurality of serving cells (carrier components).

[0017]

Next, physical channels and physical signals according to the present embodiment will be described.

[0018]

As shown in FIG. 1, the following uplink physical channels are used for uplink radio communication from terminal device 1 to base station device 3. Uplink physical channels are used to transmit information at the output of higher layers.

- Physical Uplink Control Channel (PUCCH)

- Physical Shared Channel for Uplink Data (PUSCH)

[0019]

The PUCCH is used to transmit uplink control information (UCI). One PUCCH is transmitted in one subframe. According to the present embodiment, the terminal device 1 can only transmit the PUCCH in the primary cell.

[0020]

The uplink control information includes downlink channel state information (CSI); a scheduling request (SR) to indicate a request for a PUSCH resource; and an acknowledgment of a hybrid automatic repeat request (HARQ-ACK) for downlink data (transport block, MAC PDU, downlink shared channel (DL-SCH), or physical shared channel). channel used for downlink data transmission (PDSCH)). HARQ-ACK indicates an acknowledgment (ACK) or a negative acknowledgment (NACK).

[0021]

HARQ-ACK is also referred to as ACK/NACK, HARQ feedback, HARQ-ACK feedback, HARQ response, HARQ-ACK response, HARQ information, HARQ-ACK information, HARQ control information, and HARQ-ACK control information. If the downlink data is successfully decoded, an ACK is generated for the downlink data. In case the decoding of the downlink data was not successful, a NACK is generated for the downlink data. The term "discontinuous transmission (DTX)" may mean that no downlink data has been detected. The term "discontinuous transmission (DTX)" may mean that data for which a HARQ-ACK response should be transmitted was not detected.

[0022]

The scheduling request includes a positive scheduling request or a negative scheduling request. The positive scheduling request indicates a UL-SCH resource request for initial transmission. The negative scheduling request indicates no UL-SCH resource request for initial transmission. The terminal device 1 may determine whether to send a positive scheduling request. The scheduling request being a negative scheduling request may mean that the terminal device 1 will not transmit a positive scheduling request.

[0023]

PUCCH format 1 is used to send a positive scheduling request. PUCCH format 1 is not used to send a negative scheduling request. PUCCH format 1a is used to transmit 1 bit of HARQ-ACK. PUCCH format 1b is used to transmit 2 bits of HARQ-ACK. PUCCH format 1b with channel selection is used to transmit up to 4 bits of HARQ-ACK if more than one serving cell is configured for the terminal device. The choice of a channel may cause its interpretation to change, even for the same bit value, when any one of the plurality of PUCCH resources is selected. For example, the first PUCCH resource and the second PUCCH resource may have the same bit value, but the content may be different. Channel selection may cause HARQ-ACK extension when using multiple PUCCH resources. In the present embodiment, the terminal device 1, for which two serving cells are configured, transmits only HARQ-ACK using the PUCCH format 1b with channel selection.

[0024]

The PUSCH can be used to transmit uplink data (transport block, media access control protocol data unit (MAC-PDU), uplink shared channel (UL-SCH)). The PUSCH may be used to transmit HARQ-ACK and/or channel state information along with the uplink data. The PUSCH may be used to transmit only channel state information, or to transmit only HARQ-ACK and channel state information.

[0025]

As shown in FIG. 1, the following downlink physical channels are used for downlink radio communication from base station device 3 to terminal device 1. Downlink physical channels are used to transmit output information from higher layers.

- Physical Control Format Indication Channel (PCFICH)

- Physical Downlink Control Channel (PDCCH)

- Enhanced Physical Downlink Control Channel (EPDCCH)

- Physical Shared Channel for Downlink Data (PDSCH)

[0026]

The PCFICH is used to transmit a Control Format Indicator (CFI). CFI is information related to an area (OFDM symbol) used for PDCCH transmission and/or an area (OFDM symbol) used for PDSCH transmission.

[0027]

The PDCCH and EPDCCH are used to carry downlink control information (DCI). The downlink control information is also referred to as the DCI format. The downlink control information includes a downlink grant and an uplink grant. The downlink grant is also referred to as downlink assignment or downlink assignment.

[0028]

The cyclic redundant parity check (CRC) parity bits added to the downlink control information transmitted on one PDCCH are scrambled with a cell radio network temporary identifier (C-RNTI), semi-persistent scheduling C-RNTI (SPS), or temporary C- RNTI. C-RNTI and SPS C-RNTI are identifiers for identifying a terminal device within a cell. The temporary C-RNTI is an identifier for identifying the terminal device 1 which transmitted the random access preamble in the contention-based random access procedure.

[0029]

C-RNTI and temporary C-RNTI are used to identify PDSCH transmission or PUSCH transmission in one subframe. The C-RNTI SPS is used for periodic PDSCH or PUSCH resource allocation.

[0030]

Hereinafter, unless otherwise indicated, the CRC parity bits added to the downlink control information are scrambled using C-RNTI in the present embodiment.

[0031]

The PDCCH is transmitted in a PDCCH candidate. Terminal device 1 monitors a set of PDCCH candidates in the serving cell. The set of PDCCH candidates is called the search space. The search space includes at least a common search space (CSS) and a UE-specific search space (USS). The UE-specific search space is obtained from at least one C-RNTI value set for the terminal device 1. In other words, the UE-specific search space is obtained separately for each terminal device 1. The common search space is the search space common to multiple terminal devices. devices 1, and includes a control channel element (CCE) for a given index. The CCE includes many resource elements. Snooping denotes an attempt to decode the PDCCH according to the DCI format. The common search space is included in the primary cell. The common search space is not included in the secondary cell. The terminal device 1 can only keep track of the total search space in the primary cell.

[0032]

One downlink grant may be used to schedule one PDSCH in one cell. Such a downlink grant may be used to schedule the PDSCH within the same subframe as the subframe on which the downlink grant is being transmitted.

[0033]

One uplink grant may be used to schedule one PUSCH in one cell. Such an uplink grant may be used to schedule one PUSCH in the fourth subframe or subframe following the subframe on which the uplink grant is transmitted.

[0034]

The PDSCH is used for downlink data transmission (downlink shared channel (DL-SCH)).

[0035]

UL-SCH and DL-SCH are transport channels. A transport channel is a channel used in the media access control (MAC) layer. The transport channel block applied at the MAC layer is also called a transport block (TB) or protocol data unit (PDU) of the MAC. For each transport block, a hybrid automatic repeat request (HARQ) is controlled at the MAC layer. A transport block is a block of data delivered by the MAC layer to the physical layer. At the physical layer, a transport block is mapped to a codeword, and a modulation process and an encoding process are performed for each codeword. One codeword is mapped to one layer or multiple layers.

[0036]

An example of a radio frame configuration according to the present embodiment will be described below. FIG. 2 is a diagram illustrating a schematic configuration of a radio frame according to the present embodiment. The duration of each radio frame is 10 ms. Shown in FIG. 2, the horizontal axis represents the time axis. Each of the radio frames includes 10 subframes. Each of the subframes has a length of 1 ms and is defined by two consecutive intervals. The length of each interval is 0.5 ms. More specifically, 10 subframes may be used in each 10 ms interval. A subframe is also referred to as a transmission time interval (TTI).

[0037]

An example of a slot configuration according to the present embodiment will be described below. FIG. 3 is a diagram illustrating a schematic configuration of an uplink interval according to the present embodiment. FIG. 3 illustrates the configuration of an uplink interval in a cell. As shown in FIG. 3, the horizontal axis is the time axis and the vertical axis is the frequency axis. As shown in FIG. 3, l is an SC-FDMA symbol number/index, and k is a subcarrier number/index.

[0038]

The physical signal or physical channel transmitted in each slot is expressed with a resource grid. In the uplink, a resource grid is defined by a plurality of subcarriers and a plurality of SC-FDMA symbols. Each element within the resource grid is called a resource element. The resource element is expressed by subcarrier number/index k and SC-FDMA symbol number/index l.

[0039]

The uplink interval includes a plurality of SC-FDMA symbols l (l=0, 1,..., N ^UL _symb ) in the time domain. N ^UL _symb indicates the number of SC-FDMA symbols included in one uplink slot. For the normal cyclic prefix (CP) in the uplink, N ^UL _symb is 7. In the case of extended CP in the uplink, N ^UL _symb is 6. In the present embodiment, the length of the CP corresponds to the normal CP for uplink and downlink.

[0040]

The uplink interval includes a plurality of subcarriers k (k=0, 1,..., N ^UL _RB * N ^RB _sc ) in the frequency domain. N ^UL _RB is a configuration of uplink bandwidth for a serving cell, expressed by a plurality of N ^RB _SC . N ^RB _sc is the size of the (physical) resource block in the frequency domain, expressed as the number of subcarriers. The subcarrier spacing Δf may be 15 kHz, and N ^RB _sc may be 12. Thus, N ^RB _sc may be 180 kHz. The subcarrier spacing Δf may vary for each channel and/or for each TTI/sTTI.

[0041]

The resource block is used to express the association of a physical channel with resource elements. A virtual resource block and a physical resource block are defined for a resource block. The physical channel is first mapped to a virtual resource block. The virtual resource block is then mapped to a physical resource block. One physical resource block is defined by N ^UL _symb consecutive SC-FDMA symbols in the time domain and N ^RB _sc consecutive subcarriers in the frequency domain. Therefore, one physical resource block consists of (N ^UL _symb * N ^RB _sc ) resource elements. One physical resource block corresponds to one slot in the time domain. Physical resource blocks are numbered (0, 1,..., N ^UL _RB - 1) in ascending order of frequencies in the frequency domain.

[0042]

The downlink interval according to the present embodiment includes a plurality of OFDM symbols. Since the downlink slot configuration according to the present embodiment is basically the same as that of the uplink slot, except that the resource grid is defined by a plurality of subcarriers and a plurality of OFDM symbols, a description of the downlink slot configuration will be omitted.

[0043]

In the present embodiment, a primary cell and a secondary cell are included in a PUCCH primary group. In other words, in the present embodiment, a HARQ-ACK for a transport block received in a secondary cell is transmitted to a primary cell.

[0044]

The transmission time of the HARQ-ACK according to the present embodiment will be described below.

[0045]

In the present embodiment, if the terminal device 1 detects the PDSCH in subframe n - k _p , the terminal device 1 transmits a HARQ-ACK for the PDSCH in subframe n. In other words, the transmission time of the HARQ-ACK for the PDSCH is a subframe after _kp from the subframe in which the PDSCH is transmitted. In other words, if terminal device 1 detects a PDSCH in subframe n, terminal device 1 sends a HARQ-ACK for the PDSCH in subframe n+k _p . It should be noted that the value of k _p can be configured for each serving cell. K _p for serving cell c is also indicated as k _pc . K _p for the primary cell is also indicated as k _pp . K _p for the secondary cell is also indicated as k _ps . If the terminal device 1 detects a PDSCH in subframe n - k _pp in the primary cell, the terminal device 1 transmits a HARQ-ACK for the PDSCH in subframe n. If the terminal device 1 detects a PDSCH in subframe n - k _ps in the secondary cell, the terminal device 1 transmits a HARQ-ACK for the PDSCH in subframe n.

[0046]

In the present embodiment, the transmission time of the HARQ-ACK for the PDSCH in the primary cell may be set based on at least whether a higher layer shortProcessingTime parameter is configured for the primary cell and/or whether the PDCCH used for PDSCH scheduling in the primary cell is transmitted, in any search space.

[0047]

In other words, if terminal device 1 is not configured with a higher layer shortProcessingTime parameter (RRC layer parameter) for the primary cell, the k _p value for the primary cell (k _pp ) may be 4. If the terminal device 1, a higher layer parameter shortProcessingTime is configured, and if the PDCCH used for PDSCH scheduling in subframe n in the primary cell is mapped (transmitted) to the common search space in the primary cell, the value k _p for the primary cell (k _pp ) may equal to 4. If terminal device 1 is configured with a higher layer shortProcessingTime parameter, and if the PDCCH used for PDSCH scheduling in subframe n in the primary cell is mapped to the UE-specific search space in the primary cell, the value k _p for the primary cell (k _pp ) may be 3.

[0048]

In the present embodiment, the HARQ-ACK transmission time for the PDSCH in the secondary cell to which TDD is applied may be set based on at least whether a higher layer shortProcessingTime parameter is configured in the secondary cell.

[0049]

In other words, if terminal device 1 is not configured with a higher layer shortProcessingTime parameter (RRC layer parameter) for the secondary cell, the k _p value for the secondary cell (k _ps ) may be 4. If the terminal device 1 configured higher layer shortProcessingTime parameter for the secondary cell, the k _p value for the secondary cell (k _ps ) may be 4.

[0050]

In the present embodiment, the terminal device 1 configured with a higher layer shortProcessingTime parameter for a certain serving cell may not monitor the EPDCCH in the serving cell.

[0051]

FIG. 4 is a diagram illustrating an example of a HARQ-ACK transmission time according to the present embodiment. Base station device 3 may transmit PDSCH 420 on a primary cell in subframe 400. Base station device 3 may transmit PDSCH 430 on a secondary cell in subframe 410. PDSCH 420 includes two transport blocks 421 and 422. PDSCH 430 includes two transport blocks 431 and 432.

[0052]

Terminal device 1 transmits a HARQ-ACK for PDSCH 420 and/or PDSCH 430 using PUCCH resource 440 or PUCCH resource 450 in subframe 403 in the primary cell. In other words, terminal device 1 transmits HARQ-ACK for transport blocks 421, 422, 431 and 432 using PUCCH resource 440 or PUCCH resource 450 in subframe 403 in the primary cell. In this case, subframe 400 is a _kpp subframe before subframe 403 in which HARQ-ACK transmission is performed. Subframe 410 is a k _ps subframe before subframe 403 in which HARQ-ACK transmission is performed. The value of k _pp and the value of k _ps can be determined based on the methods described above. If the value of k _pp corresponding to the primary cell and the value of k _ps corresponding to the secondary cell are the same, subframe 410 in the secondary cell is subframe 400 in the secondary cell.

[0053]

In subframe 403, PUCCH resource 440 may include four PUCCH resources for HARQ-ACK {n ⁽¹⁾ _PUCCH,0 , n ⁽¹⁾ _PUCCH,1 , n ⁽¹⁾ _PUCCH,2 , n ⁽¹⁾ _PUCCH,3 } . The PUCCH resource 450 is one PUCCH {n ⁽¹⁾ _{PUCCH, SRI} } resource for a scheduling request. The PUCCH resources for HARQ-ACK are also referred to as HARQ-ACK PUCCH resources. The PUCCH resource for the scheduling request is also referred to as the SR PUCCH resource.

[0054]

The base station device 3 may send information including the RRC layer parameter to the terminal device 1 to determine the resources 440 HARQ-ACK PUCCH {n ⁽¹⁾ _PUCCH,0 , n ⁽¹⁾ _PUCCH,1 , n ⁽¹⁾ _PUCCH,2 , n ⁽¹⁾ _PUCCH,3 }. The base station device 3 may transmit to the terminal device 1 information including an RRC layer parameter to indicate the resource 450 SR PUCCH {n ⁽¹⁾ _{PUCCH, SRI} }.

[0055]

In the present embodiment, if the HARQ-ACK and the scheduling request are transmitted in the same subframe, the terminal device 1 transmits the HARQ-ACK to the HARQ-ACK PUCCH resource 440 to execute the negative scheduling request. In case the HARQ-ACK and the scheduling request are transmitted in the same subframe, and the scheduling request is a negative scheduling request, the terminal device 1 transmits a HARQ-ACK on the dedicated HARQ-ACK PUCCH resource 440.

[0056]

In the present embodiment, if the HARQ-ACK and the scheduling request are transmitted in the same subframe, the terminal device 1 may send a HARQ-ACK to the PUCCH SR resource 450 to fulfill the positive scheduling request. In the case that the HARQ-ACK and the scheduling request are transmitted in the same subframe, and the scheduling request is a positive scheduling request, the terminal device 1 transmits a HARQ-ACK on the assigned SR PUCCH resource 450 .

[0057]

FIG. 5 is a diagram illustrating an example of HARQ-ACK(j) and transport block matching according to the present embodiment. As shown in FIG. 5, HARQ-ACK (0) corresponds to transport block 421, HARQ-ACK (1) corresponds to transport block 422, HARQ-ACK (2) corresponds to transport block 431, and HARQ-ACK (3) corresponds to transport block 432.

Next, the present embodiment will describe a method for determining a method for transmitting a HARQ-ACK when the scheduling request is a negative scheduling request, and the HARQ-ACK for a transport block detected in subframe n to k _pp in the primary cell is transmitted in subframe n in the primary cell.

[0059]

FIG. 6 is a flowchart for selecting a method for transmitting a HARQ-ACK in subframe 403 when the scheduling request according to the present embodiment is a negative scheduling request.

[0060]

As shown in FIG. 6, subframe 403 may be referred to as subframe n. The PDSCH 420 may be received in subframe n - k _pp in the primary cell. The PDSCH 430 may be received in subframe q in the secondary cell. In other words, the PDSCH 430 may be received in subframe n - k _ps in the secondary cell. As shown in FIG. 6, if the scheduling request is a negative scheduling request, the terminal device 1 transmits a HARQ-ACK using the HARQ-ACK PUCCH resource 440 allocated in subframe n in the primary cell. In other words, in FIG. 6 is a diagram illustrating a method for determining a method for transmitting a HARQ-ACK when the scheduling request is negative scheduling and a HARQ-ACK for a transport block detected in subframe n to k _pp in the primary cell is transmitted in subframe n. In the present embodiment, subframe q may be replaced by any of subframe n - 4 and subframe n - 3.

[0061]

(S600) The terminal device 1 determines the subframe q. The terminal device 1 may determine the relationship between subframe q and subframe n based on prescribed conditions. In this document, details of the prescribed conditions in S600 will be presented in FIG. 7.

[0062]

(S601) The terminal device 1 performs any of the processing of S602 and S603 based at least on whether subframe q in the secondary cell is the first prescribed subframe for transmitting HARQ-ACK in subframe n using PUCCH format 1b with channel selection. Detailed information about S601 will be presented in FIG. eight.

[0063]

(S602) The terminal device 1 transmits a HARQ-ACK using the HARQ-ACK PUCCH resource 440 in subframe n in the primary cell. The terminal device 1 transmits the HARQ-ACK using the first transmission method (HARQ-ACK transmission method using PUCCH format 1b with channel selection for FDD) to the HARQ-ACK PUCCH resource 440. Terminal device 1 may receive the PDSCH in subframe q in the secondary cell. Terminal device 1 may not receive the PDSCH in subframe q in the secondary cell.

[0064]

(S603) The terminal device 1 transmits a HARQ-ACK using the HARQ-ACK PUCCH resource 440A in subframe n in the primary cell. In this case, the resource 440A HARQ-ACK PUCCH may be part of the resource 440 HARQ-ACK PUCCH. The terminal device 1 transmits the HARQ-ACK using the second transmission method (HARQ-ACK transmission method using PUCCH format 1a or 1b for FDD) on the HARQ-ACK PUCCH resource 440A. Terminal device 1 does not receive the PDSCH in subframe q in the secondary cell.

[0065]

The base station device 3 may determine that the scheduling request is a negative scheduling request based on the reception of the HARQ-ACK in PUCCH 440.

[0066]

FIG. 7 is a diagram illustrating an example of a relationship between subframe q and subframe n in S600 shown in FIG. 6 according to the present embodiment.

[0067]

As shown in FIG. 7, subframe q may be set based on whether terminal device 1 is configured with a higher layer shortProcessingTime parameter for the secondary cell. For example, (case AAA) if terminal device 1 is not configured with a higher layer shortProcessingTime parameter for the secondary cell, q is n - 4. In other words, in this case, subframe q in the secondary cell is a subframe, four subframes preceding subframe n in which HARQ-ACK transmission is performed. (Case BBB) In case terminal device 1 is configured with a higher layer shortProcessingTime for secondary cell, q is n - 3. In other words, in this case, subframe q in secondary cell is a subframe three subframes preceding subframe n , in which HARQ-ACK transmission is performed. q may be equal to n - k _ps .

[0068]

FIG. 8 is a diagram illustrating an example of selecting the HARQ-ACK transmission method in S601 shown in FIG. 6 according to the present embodiment. As shown in FIG. 8, if subframe q in the secondary cell is not one of the first prescribed subframes for transmitting HARQ-ACK in subframe n using PUCCH format 1b with channel selection, terminal apparatus 1 performs processing in S602. If subframe q in the secondary cell is one of the first prescribed subframes for transmitting HARQ-ACK in subframe n using PUCCH format 1b with channel selection, terminal apparatus 1 performs processing in S603.

[0069]

Here, the first prescribed subframes may include an uplink subframe. The first prescribed subframes may include a special subframe with a prescribed configuration. The prescribed configuration may be configuration 0 or 5 in case a normal CP is configured for the downlink. The prescribed configuration may be configuration 0 or 4 in case an extended CP is configured for the downlink. The uplink subframe and the special subframe may be specified using the TDD-config higher level parameter. The special subframe may be composed of a downlink control time interval (DwPTS), a guard interval (GP), and an uplink control time interval (UpPTS). The higher level parameter TDD-config includes information for specifying the configuration of the special subframe. The special subframe configuration refers to at least the DwPTS length, the GP length, and/or the UpPTS length.

[0070]

Hereinafter, the first transmission method in S602 (HARQ-ACK transmission method using PUCCH format 1b with channel selection for FDD) will be described.

[0071]

According to the first transmission method, terminal device 1 transmits bits b(0) and b(1) on _PUCCH PUCCH resource n ⁽¹⁾ in subframe n using PUCCH format 1b with channel selection. Terminal device 1 can select one resource n ⁽¹⁾ _PUCCH PUCCH from four resources {n ⁽¹⁾ _PUCCH,0 , n ⁽¹⁾ _PUCCH,1 , n ⁽¹⁾ _PUCCH,2 , n ⁽¹⁾ _PUCCH,3 } PUCCH included in the HARQ-ACK PUCCH resource 440 corresponding to HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2), and HARQ-ACK (3). The terminal device 1 may set the value of b (0) and the value of b (1) according to HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2) and HARQ-ACK (3). According to the first transmission method, the terminal device 1 generates one QPSK modulation symbol from b(0) and b(1), and transmits said one modulation symbol using PUCCH format 1b.

[0072]

FIG. 9 is a diagram illustrating an example of mapping between HARQ-ACK(j) and _sPUCCH PUCCH resource n ⁽¹⁾ and b(0) to b(1) for the first transmission method according to the present embodiment. For example, if each of HARQ-ACK (0), HARQ-ACK (1), HARQ-ACK (2), and HARQ-ACK (3) is an ACK, terminal device 1 may select n ⁽¹⁾ _{PUCCH ,1} as resource n ⁽¹⁾ _PUCCH PUCCH and may set the value of each of b(0) and b(1) to 1.

[0073]

In other words, according to the first transmission method, the base station device 3 can know the HARQ-ACK corresponding to each of PDSCH 420 and PDSCH 430 based on b(0) and b(1) detected in _PUCCH resource n ⁽¹⁾ HARQ-ACK PUCCH. In particular, the base station device 3 may know the HARQ-ACK for each of the transport blocks 421, 422, 431, and 432 based on b(0) and b(1) detected in the HARQ-ACK PUCCH _PUCCH resource n ⁽¹⁾ .

[0074]

Hereinafter, the second transmission method in S603 (HARQ-ACK transmission method using PUCCH format 1a or 1b for FDD) will be described.

[0075]

In case the scheduling request is a negative scheduling request, terminal device 1 transmits bit b (0) or bits b (0) b (1) on resource n ⁽¹⁾ _PUCCH PUCCH (PUCCH 440A) in subframe n using the format 1a or 1b PUCCH. For example, if the scheduling request is a negative scheduling request, terminal device 1 may send bit b (0) on PUCCH resource n ⁽¹⁾ _PUCCH (PUCCH 440A) in subframe n using PUCCH format 1a. In case the scheduling request is a negative scheduling request, terminal device 1 may send bits b (0) b (1) on PUCCH resource n ⁽¹⁾ _PUCCH (PUCCH 440A) in subframe n using PUCCH format 1b. The PUCCH resource n ⁽¹⁾ _PUCCH (PUCCH 440A) may be defined based on at least (i) the minimum (first) number of CCEs of the CCEs configuring the PDCCH for PDSCH scheduling in subframe n - k _pp (subframe 400) in the primary cell, and (ii) cell specific parameter (higher layer parameter). PUCCH 440A may be resource n ⁽¹⁾ _PUCCH,0 PUCCH.

[0076]

According to the second transmission method, the transmitted HARQ-ACK may include HARQ-ACK (0) and may not include HARQ-ACK (1), HARQ-ACK (2), and HARQ-ACK (3). In this case, the terminal device 1 transmits a HARQ-ACK using the PUCCH format 1a.

[0077]

According to the second transmission method, the transmitted HARQ-ACK may include HARQ-ACK (0) and HARQ-ACK (1), and may not include HARQ-ACK (2) and HARQ-ACK (3). In this case, the terminal device 1 transmits a HARQ-ACK using PUCCH format 1b. In other words, according to the second transmission method, if the scheduling request is a negative scheduling request and a HARQ-ACK is transmitted in subframe n, terminal device 1 transmits a HARQ-ACK for each transport block in subframe n - k _p in the primary cell on resource 440A HARQ-ACK PUCCH.

[0078]

According to the second transmission method, the base station device 3 may know the HARQ-ACK corresponding to the PDSCH 420 based on b(0) and b(1) detected in the PUCCH HARQ-ACK resource 440A. In particular, the base station device 3 may know the HARQ-ACK for each of the transport blocks 421 and 422 based on b(0) and b(1) detected in the HARQ-ACK PUCCH _PUCCH resource n ⁽¹⁾ .

[0079]

FIG. 10 is a diagram illustrating an example of an operation that pertains to the second transmission method according to the present embodiment. In S11a, the terminal device 1 encodes the HARQ-ACK (0) into a binary bit. In S11b, the terminal device 1 encodes the HARQ-ACK (1) into a binary bit. The HARQ-ACK bit for each transport block is set to ACK or NACK. Terminal device 1 encodes ACK as binary "1" and encodes NACK as binary "0".

[0080]

In other words, if the scheduling request is a negative scheduling request, the transport block is detected in subframe n - k _pp in the primary cell, and the scheduling request and HARQ-ACK for the transport block are transmitted in subframe n of the primary cell, then terminal device 1 may select any of the first transmission method and the second transmission method as the HARQ-ACK transmission method based on whether subframe q in the secondary cell is the first prescribed subframe. In case that subframe q in the secondary cell is not one of the first prescribed subframes, the terminal apparatus 1 may select the first transmission method as the HARQ-ACK transmission method. In case the subframe q in the secondary cell is any of the first prescribed subframes, the terminal device 1 may select the second transmission method as the HARQ-ACK transmission method.

[0081]

In other words, if the scheduling request is a negative scheduling request, the transport block is detected in subframe n - k _pp in the primary cell, and the scheduling request and HARQ-ACK for the transport block are transmitted in subframe n of the primary cell, then terminal device 1 may select any of the first transmission method and the second transmission method as the HARQ-ACK transmission method based on whether the subframe in the secondary cell is the first prescribed subframe. In case the n - k _ps subframe in the secondary cell is not one of the first prescribed subframes, the terminal device 1 may select the first transmission method as the HARQ-ACK transmission method. In case the n - k _ps subframe in the secondary cell is any of the first prescribed subframes, the terminal device 1 may select the second transmission method as the HARQ-ACK transmission method.

[0082]

Next, the present embodiment will describe a method for determining a method for transmitting a HARQ-ACK when the scheduling request is a positive scheduling request, and the HARQ-ACK for a transport block detected in subframe i in the primary cell is transmitted in subframe i+k _pp primary cell.

[0083]

FIG. 11 is a flowchart for selecting a method for transmitting a HARQ-ACK in subframe i+k _pp of a primary cell when the scheduling request according to the present embodiment is a positive scheduling request.

[0084]

As shown in FIG. 11, the PDSCH 420 may be received in subframe i in the primary cell. The PDSCH 430 may be received in subframe j in the secondary cell. As shown in FIG. 11, if the scheduling request is a positive scheduling request, the terminal device 1 transmits a HARQ-ACK using the PUCCH SR resource 450 allocated in the i+k _pp subframe in the primary cell. In other words, in FIG. 11 is a diagram illustrating a method for determining a method for transmitting a HARQ-ACK when the scheduling request is positive scheduling, and a HARQ-ACK is transmitted for a transport block detected in subframe i in a primary cell. In the present embodiment, subframe j may be replaced by any of subframe i - 1, subframe i, and subframe i+1.

[0085]

[0086]

(S1101) If terminal device 1 detects one or two transport blocks in the primary cell in subframe i, terminal device 1 performs any processing in S1102 and S1103 based at least on whether subframe j in the secondary cell is the first prescribed subframe. In this case, details of S1101 will be presented in FIG. fourteen.

[0087]

(S1102) Terminal device 1 transmits a HARQ-ACK using SR PUCCH resource 450 in subframe i+k _pp (subframe 403). The terminal device 1 transmits a HARQ-ACK using a third transmission method (a method for transmitting HARQ-ACK and SR using PUCCH format 1b with channel selection for FDD) on the PUCCH SR resource 450. Subframe i+k _pp (subframe 403) may be subframe j+k _ps .

[0088]

(S1103) Terminal device 1 transmits a HARQ-ACK using SR PUCCH resource 450 in subframe i+k _pp (subframe 403). The terminal device 1 transmits the HARQ-ACK using the fourth transmission method (HARQ-ACK and SR transmission method using PUCCH format 1a or 1b for FDD) on the PUCCH SR resource 450.

[0089]

The base station device 3 may determine that the scheduling request is a positive scheduling request based on the reception of the HARQ-ACK in the SR PUCCH 450.

[0090]

PDSCH 430 may be received on the secondary cell in subframe i.

[0093]

(DDD case) When terminal device 1 is configured with a higher layer shortProcessingTime parameter for the primary cell, terminal device 1 is not configured with a higher layer shortProcessingTime parameter for the secondary cell, and the PDCCH used for scheduling a transport block in the primary cell transmitted in the common search space in subframe i, j may equal i.

[0095]

(EEE case) In the case that terminal device 1 is configured with a higher layer shortProcessingTime parameter for the primary cell, terminal device 1 is not configured with a higher layer shortProcessingTime parameter for the secondary cell, and the PDCCH used for scheduling a transport block in the primary cell, transmitted in the UE-specific search space in subframe i, j may be equal to i - 1.

[0096]

As shown in FIG. 13(c), the terminal apparatus 1 is configured with a higher layer shortProcessingTime for the primary cell. As shown in FIG. 13(c), terminal device 1 is not configured with a higher layer shortProcessingTime parameter for the secondary cell. As shown in FIG. 13(c), the PDCCH used for scheduling the PDSCH 420 is transmitted in the UE-specific search space in subframe i. As shown in FIG. 13(c), in the case of EEE, subframe j is subframe i - 1. In other words, in case of EEE, PDSCH 420 can be received in the primary cell in subframe i. PDSCH 430 may be received on the secondary cell in subframe i - 1.

[0097]

(FFF case) When terminal device 1 is configured with a higher layer shortProcessingTime parameter for the primary cell, terminal device 1 is configured with a higher layer shortProcessingTime parameter for the secondary cell, and the PDCCH used for scheduling a transport block in the primary cell is transmitted in the general search space in subframe i, j may be equal to i+1.

[0098]

In other words, in the case of FFF, PDSCH 420 may be received on the primary cell in subframe i. PDSCH 430 may be received in the secondary cell in subframe i+1.

[0099]

(Case of GGG) When terminal device 1 is configured with a higher layer shortProcessingTime parameter for the primary cell, terminal device 1 is configured with a higher layer shortProcessingTime parameter for the secondary cell, and the PDCCH used for scheduling a transport block in the primary cell is transmitted in the UE-specific search space in subframe i, j may equal i.

[0100]

[0101]

FIG. 14 is a diagram illustrating an example of selecting the HARQ-ACK transmission method in S1101 shown in FIG. 11 according to the present embodiment. As shown in FIG. 14, if one or two transport blocks are detected in the primary cell in subframe i by the terminal apparatus 1, and subframe j in the secondary cell is not one of the first prescribed subframes, the terminal apparatus 1 executes processing in S1102. For example, if two transport blocks 421 and 422 are detected by the terminal device 1 in the primary cell in subframe i, and subframe j in the secondary cell is not one of the first prescribed subframes, the terminal device 1 performs processing in S1102. In this case, the terminal device 1 may or may not detect a transport block in the secondary cell in subframe j. In other words, terminal device 1 may or may not receive PDSCH 430 in the secondary cell in subframe j.

[0102]

When one or two transport blocks are detected in the primary cell in subframe i by the terminal apparatus 1, and subframe j in the secondary cell is any of the first prescribed subframes, the terminal apparatus 1 performs processing in S1103. For example, if two transport blocks 421 and 422 are detected by the terminal device 1 in the primary cell in subframe i, and subframe j in the secondary cell is any of the first prescribed subframes, the terminal device 1 performs processing in S1103. In this case, the terminal device 1 does not detect a transport block in the secondary cell in subframe j. Terminal device 1 does not receive PDSCH 430 in the secondary cell in subframe j.

[0103]

The prescribed subframes shown in FIG. 11 may be the same as the prescribed subframes shown in FIG. eight.

[0104]

Hereinafter, the third transmission method in S1102 (HARQ-ACK and SR transmission method using PUCCH format 1b with channel selection for FDD) will be described.

[0105]

For the third transmission method, if the scheduling request is a positive scheduling request, and the HARQ-ACK request and the scheduling request are transmitted in the same subframe, terminal device 1 transmits 1 HARQ-ACK bit per serving cell on SR PUCCH resource 450 . The HARQ-ACK bit for the primary cell is mapped to b(0). The HARQ-ACK bit for the secondary cell is mapped to b(1). In this case, 1 HARQ-ACK bit per serving cell is generated in accordance with the following rules (1)-(3). According to rule (1), if one transport block is received in the serving cell, the HARQ-ACK bit for the serving cell is the HARQ-ACK bit corresponding to one transport block. According to rule (2), if two transport blocks are received in a serving cell, a HARQ-ACK bit for the serving cell is generated by spatially combining two HARQ-ACK bits corresponding to two transport blocks. According to rule (3), if a PDSCH transmission for which a HARQ-ACK response is to be received is not detected in the serving cell, the HARQ-ACK bit for the serving cell is set to NACK. According to rule (3), if a PDSCH transmission or a PDCCH transmission for which a HARQ-ACK response is to be received is not detected in the serving cell, the HARQ-ACK bit for the serving cell may be set to NACK. In this case, the PDCCH transmission may be a PDCCH transmission to indicate the cancellation of semi-persistent scheduling in the downlink.

[0106]

FIG. 15 is a diagram illustrating an example of an operation that pertains to rule (2) in the first transmission method according to the present embodiment. In S10a, terminal device 1 generates a HARQ-ACK bit for the primary cell by spatially combining HARQ-ACK (0) and HARQ-ACK (1). In S10b, terminal device 1 generates a HARQ-ACK bit for the secondary cell by spatially combining HARQ-ACK (2) and HARQ-ACK (3). In each of S10a and S10b, when each of the two incoming HARQ-ACK bits is an ACK, the HARQ-ACK generated by spatial combining is set to ACK. In S10a and S10b, if at least one of the two incoming HARQ-ACK bits is NACK, the HARQ-ACK generated by spatial combining is set to NACK.

[0107]

The HARQ-ACK bit for each serving cell is set to ACK or NACK. Terminal device 1 encodes the HARQ-ACK bit for each serving cell into a binary bit. Terminal device 1 encodes ACK as binary "1" and encodes NACK as binary "0".

[0108]

In other words, for the third transmission method, the base station device 3 may know the HARQ-ACK for each of the primary cell and the secondary cell based on the HARQ-ACK detected in the PUCC HARQ-ACK SR.

[0109]

Hereinafter, the fourth transmission method in S1103 (HARQ-ACK and SR transmission method using PUCCH format 1a or 1b for FDD) will be described.

[0110]

According to the fourth transmission method, if the scheduling request is a positive scheduling request, and the HARQ-ACK and the scheduling request are transmitted in i+k _pp subframe, the terminal device 1 transmits the HARQ-ACK on the PUCCH SR resource 450. In this case, the HARQ-ACK may include HARQ-ACK (0) and HARQ-ACK (1), and may not include HARQ-ACK (2) and HARQ-ACK (3). In this case, the terminal device 1 transmits a HARQ-ACK using PUCCH format 1b.

[0111]

According to the fourth transmission method, the transmitted HARQ-ACK may include HARQ-ACK (0) and may not include HARQ-ACK (1), HARQ-ACK (2), and HARQ-ACK (3). In this case, the terminal device 1 transmits a HARQ-ACK using the PUCCH format 1a.

[0112]

In other words, according to the fourth transmission method, if the scheduling request is a positive scheduling request, and the HARQ-ACK and the scheduling request are transmitted in the same i+k _pp subframe, the terminal apparatus 1 transmits the HARQ-ACK for each transport block in subframe i in the primary cell to resource 450 SR PUCCH in subframe i+k _pp . According to the fourth transmission method, HARQ-ACK (0) and HARQ-ACK (1) are not spatially combined.

[0113]

According to the fourth transmission method, as shown in FIG. 10, in S11a, the terminal device 1 encodes the HARQ-ACK (0) into a binary bit. In S11b, the terminal device 1 encodes the HARQ-ACK (1) into a binary bit. The HARQ-ACK bit for each transport block is set to ACK or NACK. Terminal device 1 encodes the ACK as a binary "1" and encodes the NACK as a binary "0".

[0114]

In other words, according to the fourth transmission method, the base station apparatus 3 can know the HARQ-ACK for the primary cell based on the HARQ-ACK detected in the PUCC HARQ-ACK SR. Specifically, according to the fourth transmission method, the base station device 3 can know the HARQ-ACK corresponding to each of the transport blocks 421 and 422 included in the PDSCH 420 in the primary cell based on the HARQ-ACK detected in the PUCC HARQ-ACK SR.

[0115]

In other words, if terminal device 1 is not configured with a higher level shortProcessingTime parameter for the primary cell, terminal device 1 is not configured with a higher level shortProcessingTime parameter for the secondary cell, the scheduling request is a positive scheduling request, the transport block is detected in subframe i in the primary cell and transmit the HARQ-ACK for the transport block and the scheduling request, the terminal device 1 may select the third transmission method if the subframe i in the secondary cell is not one of the first prescribed subframes. In other words, if terminal device 1 is not configured with a higher level shortProcessingTime parameter for the primary cell, terminal device 1 is not configured with a higher level shortProcessingTime parameter for the secondary cell, the scheduling request is a positive scheduling request, the transport block is detected in subframe i in the primary cell and transmit the HARQ-ACK for the transport block and the scheduling request, the terminal device 1 may select the fourth transmission method if the subframe i in the secondary cell is any of the first prescribed subframes.
