Abstract: A random access method performed by a communication node may comprise: receiving RACH configuration information; measuring a distance between a base station and a terminal or a signal characteristic value corresponding to the distance between the base station and the terminal; determining a timing offset value to be applied to random access preamble transmission using the signal characteristic value, preset threshold value, and preset timing offset value; and transmitting a random access preamble generated on the basis of the RACH configuration information to the base station, wherein the threshold value and the timing offset value are included in the RACH configuration information.
