Terminal apparatus, communication method, and integrated circuit

A terminal apparatus comprising:

• reception circuitry configured to receive a first synchronization signal, a second synchronization signal, a physical broadcast channel, and a reference signal;
• and
• detection circuitry configured to detect an identity based on the first synchronization signal and the second synchronization signal, wherein
• the reception circuitry is configured to
• receive the first synchronization signal and the second synchronization signal by a first subcarrier spacing,
• demodulate the physical broadcast channel based on the identity, and
• receive the reference signal by a second subcarrier spacing.
