Abstract:
The present invention is designed to allow co-presence with other systems, and, furthermore, achieve improved spectral efficiency in cells (for example, unlicensed bands) in which pre-transmission listening is employed. The present invention provides a transmission section that transmits a DL signal, a control section that performs listening before the DL signal is transmitted, and controls DL transmission, and a receiving section that receives a delivery acknowledgement signal (ACK/NACK) in response to the DL transmission, and the control section controls a contention window size to apply to listening based on the number of NACKs in response to a predetermined period of DL transmission.

Claim (Index 6):
The radio base station according to  claim 1 , wherein the controller maintains the contention window size or changes the contention window size to an initial value when the number of NACKs in response to the predetermined period of DL transmission is equal to or the than a predetermined threshold.
