Terminal device, base station device, and communication method for communicating according to a determined subcarrier spacing

A base station apparatus comprising:

• a transceiver;
• and
• a processing circuitry configured to control the transceiver to:
• transmit a Synchronization Signal (SS) and Physical Broadcast Channel (PBCH) in a New Radio (NR) cell, and
• provide first information indicating a starting predetermined resource of predetermined resources that are successive in a frequency direction,
• wherein the SS and PBCH are transmitted in the predetermined resources,
• wherein a subcarrier spacing for the SS and the PBCH is predefined for the predetermined resources in which the SS and PBCH are transmitted,
• wherein the SS and the PBCH are mapped to the predetermined resources based on:
• the predefined subcarrier spacing for the SS and the PBCH, and
• the first information,
• wherein the SS includes a Primary Synchronization signal (PSS) and a Secondary Synchronization Signal (SSS), and
• wherein the predetermined resources that are successive in the frequency direction are expressed as a number of multiple subcarriers in the frequency direction.
