TERMINAL DEVICE, INTEGRATED CIRCUIT, AND WIRELESS COMMUNICATION METHOD

摘要

According to the present invention, there is provided a terminal device that transmits a signal to a base station apparatus through uplink, the terminal device including: a BSR generation unit that triggers a buffer status report BSR which is used for providing the base station apparatus with information on an amount of data that is available for transmission within a buffer for a first link which is used for communication between the terminal device and a different terminal device, and that cancels the triggered buffer status report; and a configuration unit that configures a first mode or a second mode, in which, in the first mode, a resource for transmitting data for the first link is scheduled by the base station apparatus, and in the second mode, the resource for transmitting the data for the first link is selected the terminal device from a resource pool, and in which, in a case where the second mode is configured, all of the triggered buffer status reports are cancelled.

1. A terminal device that transmits a signal to a base station apparatus through uplink, the terminal device comprising:
a BSR generation unit that triggers a buffer status report (BSR) which is used for providing the base station apparatus with information on an amount of data that is available for transmission within a buffer for a first link which is used for communication between the terminal device and a different terminal device, and that cancels the triggered buffer status report; and a configuration unit that configures a first mode or a second mode, wherein, in the first mode, a resource for transmitting data for the first link is scheduled by the base station apparatus, and in the second mode, the resource for transmitting the data for the first link is selected the terminal device from a resource pool, and wherein, in a case where the second mode is configured, all of the triggered buffer status reports are cancelled.
