METHOD AND APPARATUS FOR CHANGING FREQUENCY BAND BEING USED FOR COMMUNICATION BETWEEN DEVICES SUPPORTING COMMUNICATION OF MULTI FREQUENCY BANDS

摘要

PURPOSE: A method for changing a frequency bandwidth using communication in devices is provided to change a frequency bandwidth based on communication ability supporting a first device. CONSTITUTION: A first device transmits frame for a request of frequency band change to a second device(110). The first device receives a frame for response to the frequency band change corresponding to the framer for q request of frequency band change from the second device(120). Based on a frame for response to the frequency band change, the first device selectively changes using frequency band to other frequency band(130).
