Terminal apparatus, base station apparatus, and communication method

A terminal apparatus for communicating with a base station apparatus, the terminal apparatus comprising:

• a receiver configured to receive information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel;
• a transmitter configured to transmit a transmission signal to the base station apparatus by using the first resource or the second resource, wherein the information for indicating allocation of the first resource is indicated in downlink control information,
• the information for indicating allocation of the second resource is configured in advance by the base station apparatus,
• in a case of communicating by using the first resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal, and
• in a case of communicating by using the second resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.

A base station apparatus for communicating with a terminal apparatus, the base station apparatus comprising:

• a transmitter configured to transmit information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel;
• a receiver configured to receive a signal from the terminal apparatus by using the first resource or the second resource,
• the information for indicating allocation of the first resource is indicated by using downlink control information,
• the information for indicating allocation of the second resource is configured in advance, wherein,
• by using the first resource, the signal subjected to a transmission power control based on the first transmission power control information is received, and,
• by using the second resource, the signal subjected to the transmission power control based on the second transmission power control information is received.

A communication method of a terminal apparatus for communicating with a base station apparatus, the method comprising steps of:

• receiving information for indicating allocation of a first resource, information for indicating allocation of a second resource, first transmission power control information and second transmission power control information that are for transmitting an uplink shared channel;
• and
• transmitting a transmission signal to the base station apparatus by using the first resource or the second resource, wherein
• the information for indicating allocation of the second resource is indicated in downlink control information,
• the information for indicating allocation of the second resource is configured in advance by the base station apparatus,
• in a case of communicating by using the first resource, a transmission power control is performed based on the first transmission power control information to transmit the transmission signal, and
• in a case of communicating by using the second resource, the transmission power control is performed based on the second transmission power control information to transmit the transmission signal.
