Terminal device and information processing apparatus

An information processing apparatus comprising:

• one or more processors;
• and
• a memory configured to store a program executed by the one or more processors,
• wherein the program is a program for executing
• detecting a synchronization signal for wireless communication with a base station, and
• controlling transmission of a synchronization signal for inter-device communication, and
• wherein a radio frame used in the wireless communication with the base station and a radio frame used in the inter-device communication have a same frame structure, and
• a timing of the synchronization signal for the inter-device communication in the same frame structure is same as a timing of the synchronization signal for the wireless communication with the base station in the same frame structure.

A terminal device comprising:

• a detection unit configured to detect a synchronization signal for inter-device communication transmitted by another terminal device;
• and
• a control unit configured to acquire synchronization for the inter-device communication, on the basis of a detection result of the synchronization signal,
• wherein a radio frame used in wireless communication with a base station and a radio frame used in the inter-device communication have a same frame structure, and
• a timing of the synchronization signal for the inter-device communication in the same frame structure is same as a timing of the synchronization signal for the wireless communication with the base station in the same frame structure.
