TERMINAL DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

WIPO Patent Application WO/2017/030162

A1

The present invention decreases degradation of communication performance due to interference that increases when a terminal device raises a CCA level. The present invention provides a terminal device that performs communication with a base station apparatus, the terminal device being provided with a transmission unit that transmits a frame, a transmission burst-length setting unit that changes a transmission burst-length of the frame, and a carrier sensing unit that performs carrier sensing prior to the transmission of the frame, wherein the transmission burst-length is different between the case where a threshold for the carrier sensing is set to a first value and the case where the threshold is set to a second value.
