Abstract
A terminal apparatus according to one aspect of the present invention constitutes and reports an amount-of-transmission-buffer report to be notified to a base station apparatus, based on first transmission data to the base station apparatus, which is prepared in a transmission buffer of the terminal apparatus itself, second transmission data for device-to-device data communication, and a priority level of each piece of transmission data.

10. A terminal apparatus configured and/or programmed to perform data communication with a base station apparatus, and perform inter-terminal apparatus data communication (device-to-device data communication) involving no base station apparatus, the terminal apparatus comprising:
- a first transmission buffer storing a first transmission data to the base station apparatus; and
a second transmission buffer storing a second transmission data for the device-to-device data communication; and transmission data control circuitry configured and/or programmed to constitute a buffer status report based on the first transmission data, the second transmission data, and priority levels of the first and second transmission data, wherein the first transmission data is prepared in the first transmission buffer of the terminal apparatus and the second transmission data is prepared in the second transmission buffer of the terminal apparatus; and wherein the buffer status report includes information about the amount of transmission data; and transmission circuitry configured and/or programmed to report the buffer status report to the base station apparatus. - View Dependent Claims (11, 12, 13)
