摘要： Disclosed are an apparatus and method for determining a frame structure for reducing interference between users using the same frequency band in a communication system using a cognitive radio, the method including, collecting channel status information related to a primary user with a priority to occupancy of a predetermined frequency band, executing spectrum sensing for the frequency band to check whether the primary user's traffic exists, deciding a length of a data frame to be transmitted in consideration of interference to the primary user based upon the collected channel status information if a channel in which the primary user's traffic is not present is sensed through the spectrum sensing, constructing a data frame based upon the decided frame length to transmit via the sensed channel, and re-executing the spectrum sensing for the channel, if data to be additionally transmitted exists, and rechecking whether the primary user's traffic is present.
