Claim of US Patent No. 10,512,099

1. A terminal device configured to communicate with a base station apparatus through uplink, the terminal device comprising:buffer status report (BSR)-generation circuitry configured to
trigger a BSR which is used to provide the base station apparatus with information on an amount of first link data available for transmission in a buffer of a first link which is used for communication between the terminal device and another terminal device, and
cancel the triggered BSR; and
transmission circuitry configured to perform, in a first mode or a second mode, transmission using the first link,
wherein, in the first mode, a resource for transmission of data of the first link is scheduled by the base station apparatus,
wherein, in the second mode, a resource for transmission of data of the first link is selected by the terminal device from a resource pool, and
the triggered BSR is cancelled when the second mode is configured,
wherein, in a case that the first mode is configured and a predetermined condition for triggering the buffer status report is satisfied, the buffer status report is triggered, and
wherein, in a case that the second mode is configured, the buffer status report is not triggered.
