1. A terminal apparatus being used as a master device, the terminal apparatus comprising:
- circuitry configured to;
acquire radio resource information related to a radio resource usable for a device-to-device communication not via a base station for two or more slave devices not for the master device;
determine a size of data to be transmitted or received in the device-to-device communication between the two or more slave devices based on the radio resource information and predetermined modulation and encoding schemes; and
notify the two or more slave devices which perform the device-to-device communication of the determined size of the data to be transmitted or received.

Abstract
[Object] To allow an increase in load on the base station to be suppressed when the device-to-device communication is performed.
[Solution] There is provided a terminal apparatus capable of communicating with a base station, the terminal apparatus including an acquisition unit that acquires radio resource information related to a radio resource usable for device-to-device communication not via the base station, of radio resources controllable by the base station, and a determination unit that determines a size of data to be transmitted and received in the device-to-device communication on the basis of the radio resource information.

16. A communication control apparatus of a base station, the communication control apparatus comprising:
-
circuitry configured to; assign, to a terminal apparatus, usable radio resources, from radio resources controllable by the base station, for radio communication between the base station and the terminal apparatus; and notify the terminal apparatus of the usable radio resources of the radio resources controllable by the base station, the terminal apparatus being used as a master device, wherein a part or all of the usable radio resources are used for a device-to-device communication not via the base station for two or more slave devices, not for the master device, and wherein the terminal apparatus determines a size of data to be transmitted or received in the device-to-device communication between the two or more slave devices based on radio resource information related to the usable radio resources and predetermined modulation and encoding schemes, and the terminal apparatus notifies the two or more slave devices which perform the device-to-device communication of the determined size of the data to be transmitted or received.
