PDCCH (Physical Downlink Control Channel), physical downlink shared channel (P
DSCH: Physical Downlink Shared Channel). The uplink physical channel includes a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH).
) Etc. are included.

Here, the PDCCH transmits downlink control information (DCI: Downlink Control Information) such as downlink scheduling information (downlink assignment) and uplink scheduling information (uplink grant: uplink grant) ( This is a physical channel used for notification and designation). Here, the PDCCH may be TDM (Time Division Multiplexing) with the PDSCH. The PDCCH may be PDSCH and FDM (Frequency Division Multiplexing). For example, PSCH that is FDM with PDSCH is E-PDC.

A plurality of formats are defined for transmission of downlink control information. Here, the format used for transmission of downlink control information is also referred to as a DCI format (Downlink Control Information format).

For example, DCI format 1 is used for scheduling one PDSCH in one downlink cell in the single antenna port transmission mode. DCI format 2 is used for scheduling one PDSCH in one downlink cell in the multi-antenna port mode. That is, DCI format 1 and DCI format 2 are downlink assignments used for PDSCH scheduling.

Resource allocation information for PUSCH (PUSC
Information fields such as information on modulation scheme and coding rate (MCS: Modulation and Coding Scheme) for uplink transport blocks transmitted in H) are defined. Here, one uplink assignment includes scheduling information for one PUSCH in a certain cell.

When the mobile station apparatus receives the PDSCH resource allocation on the PDCCH addressed to the mobile station apparatus, the mobile station apparatus uses the PDSCH in accordance with the instructed resource allocation to transmit a downlink signal (downlink data (downlink shared channel). (Transport block for DL-SCH: Downlink Shared Channel).

In addition, when the mobile station apparatus receives the PUSCH resource allocation on the PDCCH addressed to the mobile station apparatus, the mobile station apparatus uses the PUSCH according to the instructed resource allocation to transmit an uplink signal (uplink data (uplink data (uplink data)). A shared channel (transport block for UL-SCH: Uplink Shared Channel) and / or uplink control data (uplink control information) is transmitted.

PDSCH is downlink data (downlink shared channel (DL-SCH)).
Transport channel) or paging information (transport block for paging channel (PCH)). The base station apparatus transmits downlink data to the mobile station apparatus using the PDSCH assigned by the PDCCH.

Here, the downlink data indicates, for example, user data, and is DL-SC.
H is a transport channel. Here, the downlink transport block is a unit handled in a MAC (Medium Access Control) layer. Also, the downlink transport block is associated with a codeword in the physical layer. That is, the downlink transport block is a unit of data supplied (delivered) from the MAC layer to the physical layer.

Furthermore, PUSCH mainly uses uplink data (uplink shared channel (UL-
This is a physical channel used to transmit a transport block) for SCH). A mobile station apparatus transmits uplink data to a base station apparatus using PUSCH allocated by PDCCH. Moreover, when a base station apparatus schedules PUSCH (PUSCH resource) to a mobile station apparatus, uplink control information (UCI: Uplink Control Information) is also transmitted using PUSCH.

Here, the uplink data indicates, for example, user data, and UL-SC.
H is a transport channel. Here, the uplink transport block is a unit handled in the MAC layer. Further, the uplink transport block is associated with a codeword in the physical layer. That is, the uplink transport block is a unit of data supplied (delivered) from the MAC layer to the physical layer.

Moreover, PUCCH is a physical channel used in order to transmit uplink control information. Here, the uplink control information includes HARQ-ACK. The uplink control information includes CSI. Further, CSI includes a channel quality indicator (CQI), a precoding matrix indicator (PMI), and a rank indicator (RI). Also, the uplink control information includes a scheduling request (SR) used for requesting allocation of resources for the mobile station apparatus to transmit uplink data.

Here, a plurality of formats are defined (supported) for the PUCCH. A format supported for PUCCH (a format supported by PUCCH) is also referred to as a PUCCH format.

   For example, on-off-keying is applied to PUCCH format 1 as a modulation method. For example, the mobile station apparatus can transmit a scheduling request using PUCCH format 1.

For example, BPSK (Binary Phase Shift Keying) is applied to the PUCCH format 1a as a modulation method. For example, the mobile station apparatus can transmit 1-bit HARQ-ACK per subframe using the PUCCH format 1a. Further, the mobile station apparatus can transmit HARQ-ACK corresponding to a single cell (hereinafter also referred to as single HARQ-ACK (single HARQ-ACK)) using PUCCH format 1a. .

Here, the HARQ-ACK corresponding to a single cell includes a single cell (a single cell P
HARQ-ACK for the downlink transport block transmitted by DSCH) is included. Here, for example, the base station apparatus can set the downlink transmission mode for the mobile station apparatus in each serving cell. For example, when a downlink transmission mode in which one downlink transport block can be transmitted is set, the base station apparatus transmits one downlink transport block using PDSCH. For example, when a mode in which one downlink transport block can be transmitted is set, the mobile station apparatus can transmit 1-bit HARQ-ACK corresponding to a single cell.

   Further, for example, QPSK (Quadrature Phase Shift Keying) is applied as a modulation method to the PUCCH format 1b. For example, the mobile station apparatus can transmit HARQ-ACK of 2 bits per subframe using the PUCCH format 1b. For example, the mobile station apparatus can transmit HARQ-ACK corresponding to a single cell using PUCCH format 1b.

Here, for example, when the downlink transmission mode capable of transmitting up to two downlink transport blocks is set, the base station apparatus uses PDSCH to store up to two downlink transport blocks. Can be sent.

If it is detected, it is determined whether to transmit CSI on PUSCH or on PUCCH according to the second parameter.

By transmitting HARQ-ACK and / or CSI as described above, the mobile station apparatus can transmit HARQ-ACK and / or CSI using an appropriate PUCCH format depending on the situation. HARQ-ACK and / or CSI can be transmitted efficiently.

For example, a situation in which a mismatch occurs in the number of cells used for communication between the base station device and the mobile station device (the number of cells used for communication is determined by the base station device using higher layer signals). When changed, the mobile station apparatus can transmit HARQ-ACK using PUCCH format 1a / 1b. That is, the base station device and the mobile station device can continue communication only in a single cell (only the primary cell) even in a situation where the number of cells used for communication does not match.

In addition, for example, a situation in which there is a mismatch in the number of cells used for communication between the base station device and the mobile station device (by the base station device using a higher layer signal, When the number is changed), the mobile station apparatus can transmit HARQ-ACK and CSI simultaneously using PUCCH format 2 / 2a / 2b. That is, the base station device and the mobile station device can continue communication only in a single cell (only the primary cell) even in a situation where the number of cells used for communication does not match. In addition, the base station apparatus can perform efficient scheduling based on CSI.

Here, basically, PUCCH format 1a / 1b and PUCCH format 2 / 2a / 2b have a smaller number of transmittable bits than PUCCH format 3, but are code-multiplexed into a single physical resource block. There are many things you can do. That is, in a situation where the mobile station device transmits HARQ-ACK corresponding to a single cell (transmits HARQ-ACK corresponding to transmission of one PDSCH in the primary cell), PUCCH format 1a / 1b or By transmitting HARQ-ACK using PUCCH format 2 / 2a / 2b, HARQ-ACK and CSI can be efficiently transmitted.

In addition, the mobile station apparatus performs HARQ-ACK corresponding to a single cell (HA with a small amount of information)
When transmitting (RQ-ACK), PUCCH format 1a / 1b or PUCCH format 2 / 2a / 2b is used, and HARQ-ACK corresponding to a single cell or multiple cells (the amount of information can be increased). By using PUCCH format 3 when transmitting a reliable HARQ-ACK), it is possible to efficiently transmit HARQ-ACK and / or CSI using an appropriate format depending on the situation.

ACK / NACK is required to have a lower error rate than CSI. That is, ACK / NACK transmitted in PUCCH format 1a / 1b has a lower error rate than ACK / NACK transmitted in PUCCH format 2 / 2a / 2b. That is, when only ACK / NACK is transmitted using PUCCH format 3, the ACK / NACK error rate is lower than when ACK / NACK and CSI are transmitted using PUCCH format 3.

Further, when the mobile station apparatus transmits HAQR-ACK corresponding to a single cell, it uses PUCCH format 1a / 1b or PUCCH format 2 / 2a / 2b based on the first parameter. It is possible to efficiently transmit HARQ-ACK and / or CSI using an appropriate format.

Further, when the mobile station apparatus transmits HAQR-ACK corresponding to a single cell or a plurality of cells, based on the second parameter, by using PUCCH format 3, only ACK / NACK, Alternatively, ACK / NACK and CSI can be transmitted efficiently.

In addition, the mobile station apparatus that is set to simultaneously transmit PUCCH and PUSCH transmits HARQ-ACK and CSI as described above, so that the base station apparatus sets the second parameter, so that CSI is changed to PUSCH. Can be switched between transmitting on PUCCH and transmitting on PUCCH. That is, information for instructing whether to transmit CSI using PUSCH or PUCCH is not required, and HARQ-ACK and CSI can be transmitted efficiently.

Here, basically, the amount of information that can be transmitted on the PUCCH is limited. Also, PUSCH
The amount of information that can be transmitted with is not limited. That is, only a small amount of information can be transmitted on the PUCCH, and a large amount of information can be transmitted on the PUSCH. On the other hand, the PUCCH is designed to be suitable for transmission of uplink control information (HARQ-ACK, CSI, scheduling request). For example, PUCCH can be transmitted with high power. The PUSCH is designed to be suitable for transmission of uplink transport blocks.

That is, the base station apparatus transmits CSI on PUSCH and PUCC depending on the situation.
It is possible to switch the transmission of CSI in H using the second parameter. For example, when transmitting HARQ-ACK with a large amount of information on PUCCH, the base station apparatus can transmit CSI on PUSCH. Moreover, when transmitting HARQ-ACK with a small amount of information by PUCCH, the base station apparatus can transmit CSI by PUCCH.

Also, for example, when transmitting CSI with a large amount of information, the base station apparatus can transmit CSI using PUSCH. Moreover, when transmitting CSI with little information amount, CSI can be transmitted by PUCCH.

Further, for example, when the base station apparatus wants to receive ACK / NACK correctly, the base station apparatus sets using the third parameter so that the mobile station apparatus transmits only ACK / NACK on the PUCCH. For example, when the base station apparatus wants to receive CSI correctly, the base station apparatus sets using the third parameter so that the mobile station apparatus transmits ACK / NACK and CSI on PUCCH.

As described above, the base station apparatus performs HARQ-ACK and / or C depending on the situation.
By switching the SI transmission method, HARQ-ACK and / or CSI can be efficiently transmitted.

Further, the “computer-readable recording medium” dynamically holds a program for a short time, like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line.
