Base station apparatus, terminal apparatus, and communication method

A base station apparatus comprising:

• a transmission unit configured to transmit a first downlink control information (DCI);
• and
• a determination unit configured to determine reception of a first physical uplink shared channel (PUSCH), wherein:
• the first PUSCH is scheduled by the first DCI,
• a value of a first PUSCH procedure preparation time for the first PUSCH is a first value in a case that a first condition is not satisfied,
• the value of the first PUSCH procedure preparation time is a value acquired by adding a second value to the first value in a case that the first condition is satisfied, and
• the determination unit determines the reception of the first PUSCH in a case that a number of symbols between the first DCI and the first PUSCH is equal to or greater that a number of symbols corresponding to the value of the first PUSCH procedure preparation time.

A communication method for a terminal apparatus in a radio communication system, the communication method comprising:

• receiving a first downlink control information (DCI);
• and
• transmitting a first physical uplink shared channel (PUSCH), wherein:
• the first PUSCH is scheduled by the first DCI,
• a value of a first PUSCH procedure preparation time for the first PUSCH is a first value in a case that a first condition is not satisfied,
• the value of the first PUSCH procedure preparation time is a value acquired by adding a second value to the first value in a case that the first condition is satisfied, and
• the transmission of the first PUSCH is determined in a case that a number of symbols between the first DCI and the first PUSCH is equal to or greater than a number of symbols corresponding to the value of the first PUSCH procedure preparation time.
