Abstract

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). A method of determining a frequency-domain offset parameter of a preamble in a random access channel and a corresponding user equipment (UE) is provided. The method includes obtaining a random access channel subcarrier spacing Δf RA , a preamble length L RA and a uplink (UL) channel subcarrier spacing Δf from a base station and determining a frequency-domain offset parameter k of a preamble in a random access channel based on the obtained random access channel subcarrier spacing Δf RA , preamble length L RA and UL channel subcarrier spacing Δf. Other embodiments of the disclosure further provide a random access method, a method for configuring random access information and related device, and a corresponding computer readable medium.
