Abstract
A terminal apparatus (1) and a base station apparatus (3) efficiently communicate with each other by using an uplink signal. The terminal apparatus (1) receives information for indicating a configuration of an added UpPTS, transmits an SRS and a PUSCH, and transmits capability information used for individually indicating (i) whether the terminal apparatus (3) supports the SRS transmission in the added UpPTS included in a special subframe, and (ii) whether the terminal apparatus (3) supports the PUSCH transmission in the added UpPTS included in the special subframe.

Claim
1. A terminal apparatus which communicates with a base station apparatus using a serving cell, comprising:
determining circuitry configured to determine a Time Division Duplex (TDD) uplink/downlink (UL/DL) configuration of the serving cell,
a receiver configured to receive a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) in subframe n; and
a transmitter configured to transmit a Physical Uplink Shared Channel (PUSCH) in subframe n+k based on a detection of the PDCCH, wherein
k is determined based on a first table in a case that the terminal apparatus is not configured with a first parameter of an RRC layer, wherein the first parameter indicates a number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols configured for a transmission of the PUSCH in an Uplink Pilot Time Slot (UpPTS) of a special subframe,
k is determined based on a second table which is different from the first table in a case that the terminal apparatus is configured with the parameter, and
the first table and the second table independently indicate k corresponding to (a) the TDD UL/DL configuration and (b) n.
2. The terminal apparatus of claim 1, wherein
the transmitter is further configured to transmit a Sounding Reference Signal (SRS) and capability information, wherein
the capability information includes a first indication indicating whether or not the terminal apparatus supports a transmission of the SRS in SC-FDMA symbols of the UpPTS, wherein a number of the SC-FDMA symbols is indicated by a second parameter of the RRC layer, and
the capability information includes a second indication indicating whether or not the terminal apparatus supports a transmission of the PUSCH in SC-FDMA symbols of the UpPTS, wherein a number of the SC-FDMA symbols is indicated by the first parameter of the RRC layer.
3. A method performed by a terminal apparatus which communicates with a base station apparatus using a serving cell, comprising:
determining a Time Division Duplex (TDD) uplink/downlink (UL/DL) configuration of the serving cell,
receiving a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) in subframe n; and
transmitting a Physical Uplink Shared Channel (PUSCH) in subframe n+k based on a detection of the PDCCH, wherein
k is determined based on a first table in a case that the terminal apparatus is not configured with a first parameter of an RRC layer, wherein the first parameter indicates a number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols configured for a transmission of the PUSCH in an Uplink Pilot Time Slot (UpPTS) of a special subframe,
k is determined based on a second table which is different from the first table in a case that the terminal apparatus is configured with the parameter, and
the first table and the second table independently indicate k corresponding to (a) the TDD UL/DL configuration and (b) n.
4. A base station apparatus which communicates with a terminal apparatus using a serving cell, comprising:
determining circuitry configured to determine a Time Division Duplex (TDD) uplink/downlink (UL/DL) configuration of the serving cell,
a transmitter configured to transmit, to the terminal apparatus, a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) in subframe n; and
a receiver configured to receive a Physical Uplink Shared Channel (PUSCH) in subframe n+k, wherein the PUSCH is transmitted by the terminal apparatus based on a detection of the PDCCH, wherein
k is determined based on a first table in a case that the terminal apparatus is not configured with a first parameter of an RRC layer, wherein the first parameter indicates a number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols configured for a transmission of the PUSCH in an Uplink Pilot Time Slot (UpPTS) of a special subframe,
k is determined based on a second table which is different from the first table in a case that the terminal apparatus is configured with the parameter, and
the first table and the second table independently indicate k corresponding to (a) the TDD UL/DL configuration and (b) n.
5. The base station apparatus of claim 4, wherein
the receiver is further configured to receive a Sounding Reference Signal (SRS) and capability information, wherein
the capability information includes a first indication indicating whether or not the terminal apparatus supports a transmission of the SRS in SC-FDMA symbols of the UpPTS, wherein a number of the SC-FDMA symbols is indicated by a second parameter of the RRC layer, and
the capability information includes a second indication indicating whether or not the terminal apparatus supports a transmission of the PUSCH in SC-FDMA symbols of the UpPTS, wherein a number of the SC-FDMA symbols is indicated by the first parameter of the RRC layer.
6. A method performed by a base station apparatus which communicates with a terminal apparatus using a serving cell, comprising:
determining a Time Division Duplex (TDD) uplink/downlink (UL/DL) configuration of the serving cell,
transmitting, to the terminal apparatus, a Physical Downlink Control Channel (PDCCH) including Downlink Control Information (DCI) in subframe n; and
receiving a Physical Uplink Shared Channel (PUSCH) in subframe n+k, wherein the PUSCH is transmitted by the terminal apparatus based on a detection of the PDCCH, wherein
k is determined based on a first table in a case that the terminal apparatus is not configured with a first parameter of an RRC layer, wherein the first parameter indicates a number of Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols configured for a transmission of the PUSCH in an Uplink Pilot Time Slot (UpPTS) of a special subframe,
