Terminal apparatus, base station apparatus, communication method, and integrated circuit

A terminal apparatus configured to communicate with a base station apparatus via a cell, the terminal apparatus comprising:

• reception circuitry configured to
• receive first system information broadcasted by using a first subcarrier spacing, the first system information including information of a second subcarrier spacing, and
• receive second system information broadcasted by using the second subcarrier spacing, the second system information including information of a third subcarrier spacing;
• and
• transmission circuitry configured to transmit a random access preamble based on the second system information.

A base station apparatus configured to communicate with a terminal apparatus via a cell, the base station apparatus comprising:

• transmission circuitry configured to
• transmit, first system information broadcasted by using a first subcarrier spacing, the first system information including information of a second subcarrier spacing, and
• transmit second system information broadcasted by using the second subcarrier spacing, the second system information including information of a third subcarrier spacing;
• and
• reception circuitry configured to receive a random access preamble based on the second system information.
