Terminal device, communication method, and integrated circuit

A communication method of a terminal device that communicates with a base station device, comprising:

• a step of receiving information related to a first configuration and/or information related to a second configuration, and a grant;
• a step of transmitting, in a case of an uplink signal being scheduled based on the grant, the uplink signal to the base station device in an earliest uplink subframe on or after a designated subframe from a subframe in which the grant was detected;
• in a case of both the first configuration and the second configuration being configured,
• if the grant is a first grant, a step of configuring a transmit power of the uplink signal based on a first uplink power control method if the uplink subframe is included in a first subframe subset, and configuring the transmit power of the uplink signal based on a second uplink power control method if the uplink subframe is included in a second subframe subset;
• and
• if the grant is a second grant, a step of configuring the transmit power of the uplink signal based on the same uplink power control method, irrespectively of whether the uplink subframe is included in the first subframe subset or the second subframe subset.

An integrated circuit mounted onboard a terminal device that communicates with a base station device, and causing the terminal device to exhibit:

• a function of receiving information related to a first configuration and/or information related to a second configuration, and a grant;
• a function of transmitting, in a case of an uplink signal being scheduled based on the grant, the uplink signal to the base station device in an earliest uplink subframe on or after a designated subframe from a subframe in which the grant was detected;
• in a case of both the first configuration and the second configuration being configured,
• if the grant is a first grant, a function of configuring a transmit power of the uplink signal based on a first uplink power control method if the uplink subframe is included in a first subframe subset, and configuring the transmit power of the uplink signal based on a second uplink power control method if the uplink subframe is included in a second subframe subset;
• and
• if the grant is a second grant, a function of configuring the transmit power of the uplink signal based on the same uplink power control method, irrespectively of whether the uplink subframe is included in the first subframe subset or the second subframe subset.
