METHOD FOR FINE TA ADJUSTMENT, AND NODE USING SAME

摘要

The present specification relates to a method by which a device performs data transmission or reception in a wireless communication system, comprising: performing an initial access operation with other devices; and transmitting first information (M-N) times and second information N times to the other devices, wherein M and N are respectively natural numbers, M is greater than N, and the first information and the second information are respectively the information related to timing adjustment, the first information has a value differing from that of the second information, and the data transmission or reception with the other devices is performed on the basis of a timing advance (TA) value, which is based on the average of all of the first information transmitted (M-N) times and the second information transmitted N times.
