TERMINAL DEVICE AND INFORMATION PROCESSING APPARATUS

摘要

[Object] To simplify the operation of a terminal device for performing D2D communication in which the same communication scheme as the communication scheme of cellular communication is adopted.;[Solution] Provided is a terminal device including: a detection unit configured to detect a synchronization signal for wireless communication with a base station; and a control unit configured to control transmission of a synchronization signal for inter-device communication. 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. 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.

1. A terminal device comprising:
circuitry configured to
detect a first synchronization signal transmitted by a base station, the first synchronization signal having a first identification selected from among a first subset of a plurality of synchronization signal identifiers;detect a second synchronization signal transmitted by another terminal device, the second synchronization signal having a second identification selected from among a second subset of the plurality of synchronization signal identifiers;acquire synchronization for performing device-to-device (D2D) communication based on at least one of the first synchronization signal or the second synchronization signal; andcontrol transmission of a synchronization signal for the D2D communication according to a frame structure that is used in the wireless communication with the base station and the D2D communication.
