Hereinafter, the setting method of UL / DL setting will be described.

The base station apparatus 3 sets UL / DL settings for each of the serving cells. That is, UL / DL settings are defined for each of a plurality of serving cells. The base station apparatus 3 uses the X-th information indicating the UL / DL setting for the serving cell as a system information block type 1 message, a system information message, an RRC message, a MAC CE (Control Element), and physical layer control information (for example, , DCI format) and may be transmitted.

Hereinafter, the timing of HARQ-ACK transmission in the uplink will be described.

Terminal apparatus 1 transmits HARQ-ACK in uplink subframe n based on detection of PDSCH transmission in subframe nk in a serving cell. Here, the PDSCH targets the terminal device 1 (intendedinfor the terminal device 1). Also, here, the PDSCH is a PDSCH (PDSCH for which HARQ-ACK hall be provided) to which HARQ-ACK must be provided. Here, k is included in a downlink association set K.

FIG. 8 is a diagram illustrating an example of the downlink association set K in the present embodiment. In FIG. 8, when the placeholder UL / DL setting is 1 and the subframe number of the subframe n is 2, the downlink association set K includes {k ₀ = 7, k ₁ = 6}. That is, in FIG. 8, when the placeholder UL / DL setting is 1 and the subframe number of subframe n is 2, the terminal device 1 transmits PDSCH in subframe n-7 and / or subframe n Based on the detection of PDSCH transmission at −6, HARQ-ACK is transmitted in uplink subframe n.

The placeholder UL / DL setting in FIG. 8 refers to the UL / DL setting indicated by the Xth information or the DL reference UL / DL setting (downlink reference uplink-downlink configuration). That is, the UL / DL setting indicated by the Xth information and the DL reference UL / DL setting are the subframe nk in which the PDSCH is arranged and the subframe in which HARQ-ACK corresponding to the detection of the PDSCH is transmitted. Used to specify (select, determine) the correspondence with n. The DL reference UL / DL configuration for the timing of HARQ-ACK transmission in the uplink is defined for each serving cell.

Whether the placeholder UL / DL setting refers to the UL / DL setting indicated by the Xth information or the DL reference UL / DL setting depends on the following conditions (1) to a part of the condition (12): Alternatively, it may be specified (selected, determined) based on the whole. Whether the placeholder UL / DL setting refers to the UL / DL setting indicated by the Xth information or the DL reference UL / DL setting may be specified (selected, determined) for each PUCCH cell group. .

Condition (1): Whether the UL / DL settings for all serving cells are the same Condition 2: Whether at least two UL / DL settings among the UL / DL settings for the serving cell are different Condition 3 : UL / DL setting for primary cell and UL / DL setting for secondary cell (PUCCH secondary cell and / or non-PUCCH secondary cell) are the same. Condition (4): Primary cell included in primary PUCCH cell group Whether the UL / DL setting for the PUCCH cell group and the UL / DL setting for the PUCCH secondary cell included in the secondary PUCCH cell group are the same. Condition (5): The UL / DL setting for all serving cells included in one PUCCH cell group is the same. or not· Case (6): Whether or not at least two UL / DL settings are different among UL / DL settings for serving cells included in one PUCCH cell group.

Condition (12): Whether the serving cell is included in the primary PUCCH cell group or the secondary PUCCH cell group.

Inter-band TDD carrier aggregation is carrier aggregation in which a plurality of serving cells belonging to different bands and to which TDD is applied are aggregated. Whether the terminal apparatus 1 supports simultaneous transmission / reception for inter-band TDD carrier aggregation depends on a combination of bands to which the serving cells to be aggregated belong.

That is, the terminal device 1 does not support simultaneous transmission / reception for inter-band TDD carrier aggregation for the first band combination, and for inter-band TDD carrier aggregation for the second band combination. Simultaneous transmission and reception may be supported. That is, whether or not the terminal device 1 satisfies the condition (12) depends on a combination of bands to which a plurality of aggregated serving cells belong. That is, the HARQ-ACK transmission timing in the uplink may be based on a combination of bands to which a plurality of aggregated serving cells belong.
