Abstract
The present invention allows a terminal apparatus and a base station apparatus to efficiently communicate with each other by using an uplink signal. A terminal apparatus receives a PDCCH including a DCI format, and performs a transmission using a PUSCH based on detection of the PDCCH, and determines to transmit, based on at least (i) whether a subframe in which the transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of SC-FDMA symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
Claims12
A terminal apparatus comprising:
- a receiver configured to receive a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- and
- a transmitter configured to perform a transmission using a Physical Uplink Shared Channel (PUSCH) based on detection of the PDCCH, wherein
- the transmitter determines to transmit, based on at least (i) whether a subframe in which the transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
A base station apparatus comprising:
- a transmitter configured to perform a transmission of a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- and
- a receiver configured to perform reception using a Physical Uplink Shared Channel (PUSCH) corresponding to the transmission of the PDCCH, wherein
- the receiver determines to receive, based on at least (i) whether a subframe in which a transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
A communication method used for a terminal apparatus, the communication method comprising the steps of:
- receiving a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- performing a transmission using a Physical Uplink Shared Channel (PUSCH) based on detection of the PDCCH;
- and
- determining to transmit, based on at least (i) whether a subframe in which the transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
A communication method used for a base station apparatus, the communication method comprising the steps of:
- performing a transmission of a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- performing reception using a Physical Uplink Shared Channel (PUSCH) corresponding to the transmission of the PDCCH;
- and
- determining to receive, based on at least (i) whether a subframe in which a transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
An integrated circuit mounted on a terminal apparatus, the integrated circuit comprising:
- a reception circuit configured to receive a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- and
- a transmission circuit configured to perform a transmission using a Physical Uplink Shared Channel (PUSCH) based on detection of the PDCCH, wherein
- the transmission circuit determines to transmit, based on at least (i) whether a subframe in which the transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
An integrated circuit mounted on a base station apparatus, the integrated circuit comprising:
- a transmission circuit configured to perform a transmission of a Physical Downlink Control Channel (PDCCH) including a Downlink Control Information (DCI) format;
- and
- a reception circuit configured to perform reception using a Physical Uplink Shared Channel (PUSCH) corresponding to the transmission of the PDCCH, wherein
- the reception circuit determines to receive, based on at least (i) whether a subframe in which a transmission using the PUSCH is performed is an uplink subframe or a special subframe, (ii) a subframe number of a subframe in which the PDCCH including the DCI format is detected, or (iii) the number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols that transmit the PUSCH in one subframe, uplink control information by using the PUSCH that includes no transport block.
