Abstract
The present disclosure suggests a method for adjusting the size of a contention window of a base station/terminal. The method comprises transmitting a physical downlink shared channel (PDSCH) to a user equipment (UE) through a frequency bandwidth, receiving an acknowledgement/negative-acknowledgement (ACK/NACK) signal for the PDSCH from the UE, and adjusting the contention window based on the ACK/NACK signal, wherein based on the frequency bandwidth overlapping with a plurality of frequency bands, the BS adjusts the contention window for each of the plurality of frequency bands based on the ACK/NACK signal.
