原文（中国語）

The present disclosure provides a random access method. A method according to an embodiment of the present disclosure, performed by a terminal using an asynchronous grant-free non-orthogonal multiple access scheme, may comprise the steps of: acquiring random access preamble generation information from a base station; generating a primary random access preamble on the basis of the random access preamble generation information; and transmitting the generated primary random access preamble to the base station.
