Abstract: The present disclosure provides a method (300) in a Radio Unit (RU) for facilitating Clear Channel Assessment (CCA). The method (300) comprises: detecting (S310), in a first transmission period while the RU is operating in a first channel, whether one or more candidate channels in proximity to the first channel are unoccupied; determining (S320), when the first channel is not clear for transmission in a second transmission period, whether any of the one or more candidate channels that is detected to be unoccupied is clear for transmission in the second transmission period; and selecting (S330) one of the one or more candidate channels that is determined to be clear, for transmission in the second transmission period.
