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.
Claims8
1-9. (canceled)
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.
A communication system comprising:
- a terminal apparatus configured and/or programmed to perform inter-terminal apparatus data communication (device-to-device data communication) involving no base station apparatus;
- and
- a base station apparatus configured and/or programmed to allocate to the terminal apparatus, a transmission resource for the device-to-device data communication,
- a first transmission data to the base station apparatus is prepared in a first transmission buffer of the terminal apparatus and a second transmission data for the device-to-device data communication is prepared in a second transmission buffer of the terminal apparatus and
- wherein the first transmission data, the second transmission data, and the information are to be used for the terminal apparatus to constitute and report an buffer status report to the base station apparatus and
- wherein the buffer status report includes information about the amount of transmission data.
A notification method that is applied to a terminal apparatus configured and/or programmed to perform inter-terminal apparatus data communication (device-to-device data communication) involving no base station apparatus, the notification method at least comprising:
- a step of constituting an buffer status report based on first transmission data to the base station apparatus, second transmission data for the device-to-device data communication, and priority levels of the first and second transmission data,
- wherein the first transmission data is prepared in a first transmission buffer of the terminal apparatus and the second transmission data are prepared in a second transmission buffer of the terminal apparatus;
- and
- wherein the buffer status report includes information about the amount of transmission data;
- and
- a step of reporting the buffer status report to the base station apparatus.
An integrated circuit that is built into a terminal apparatus configured and/or programmed to perform inter-terminal apparatus data communication (device-to-device data communication) involving no base station apparatus, the integrated circuit causing the terminal apparatus to perform:
- a function of constituting an buffer status report based on first transmission data to the base station apparatus, second transmission data for the device-to-device data communication, and priority levels of the first and second transmission data
- wherein the first transmission data is prepared in a first transmission buffer of the terminal apparatus and the second transmission data is prepared in a second transmission buffer of the second terminal apparatus;
- wherein the buffer status report includes information about the amount of transmission data;
- and
- a function of reporting the buffer status report to the base station apparatus.
