Abstract: A method for transmitting a downlink in an unlicensed band is provided. A plurality of base stations in a first group determine a first delay time from a reference time point for initiating a clear channel assessment (CCA) in the unlicensed band. The plurality of base stations execute CCA during a CCA section after the first delay time from the reference time point, and check whether a channel is idle. If the channel is idle, the plurality of base stations simultaneously transmits a downlink.
