Claim of US Patent No. 10,251,184

1. A method of controlling clear channel assessment (CCA) timing by a base station in a wireless communication system using an unlicensed band, the method comprising: determining whether to change CCA timing by comparing a number of at least one of continuous successes or continuous failures of the CCA with a predetermined threshold value; randomizing the CCA timing when the CCA timing is determined to be changed; and updating a frame based on the CCA timing changed according to the randomization of the CCA timing.
