Title:

METHOD AND DEVICE FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/058329

Kind Code:

A1

Abstract:

An operation method of a terminal according to an embodiment of a method and device for random access in a wireless communication system comprises the steps of: receiving random access channel (RACH) configuration information from a base station included in a first network; generating a random access (RA) preamble including a plurality of different preamble sequences on the basis of the RACH configuration information; mapping the RA preamble to a first frequency domain; and transmitting, to the base station, the PA preamble mapped to the first frequency domain, wherein the size of the bandwidth occupied by the first frequency domain and the size of the bandwidth occupied by a physical uplink shared channel (PUSCH) in the first network may be set to have an integer multiple relationship with each other on the basis of the RACH configuration information.
