Abstract
A terminal which performs communication with at least one base station, includes means for detecting a field indicating whether or not a transmission request of a sounding reference signal (SRS) is made from a downlink control information (DCI) format, means for generating a base sequence of the SRS on the basis of a first parameter in a case where the field indicates a transmission request of the SRS in a first DCI format, and means for generating a base sequence of the SRS on the basis of a second parameter in a case where the field indicates a transmission request of the SRS in a second DCI format.

1-27. (canceled)
A terminal apparatus comprising:
- a transmission circuitry configured to transmit a sounding reference signal (SRS) in a certain subframe, wherein
- the transmission circuitry is configured
- to transmit an SRS within a first transmit power based on a first accumulated value in a case where the certain subframe belongs to a first subframe subset, and
- to transmit an SRS within a second transmit power based on a second accumulated value in a case where the certain subframe belongs to a second subframe subset.
A base station apparatus comprising:
- a reception circuitry configured
- to receive, in a subframe belonging to a first subframe subset, a sounding reference signal with a first transmit power, and
- to receive, in a subframe belonging to a second subframe subset, a sounding reference signal with a second transmit power;
- and
- a transmission circuitry configured to transmit, via a downlink control information format, a transmission power control command corresponding to each of a first accumulated value and a second accumulated value, wherein
- the first accumulated value is used for setting of the first transmit power, and
- the second accumulated value is used for setting of the second transmit power.
A method for a terminal apparatus comprising:
- transmitting a sounding reference signal in a certain subframe,
- transmitting a sounding reference signal with a first transmit power based on a first accumulated value in a case where the certain subframe belongs to a first subframe subset, and
- transmitting a sounding reference signal with a second transmit power based on a second accumulated value in a case where the certain subframe belongs to a second subframe subset.
A method for a base station apparatus comprising:
- receiving a sounding reference signal with a first transmit power in a subframe belonging to a first subframe subset,
- receiving a sounding reference signal with a second transmit power in a subframe belonging to a second subframe subset, and
- transmitting, via a downlink control information format, a transmission power control command corresponding to each of a first accumulated value and a second accumulated value, wherein
- the first accumulated value is used for setting of the first transmit power, and
- the second accumulated value is used for setting of the second transmit power.
