Abstract

A random access configuration information based on a reference SCS may allow for a unified coordinate system used by the base station and UEs that describes the time-frequency resource configuration for a two-step RACH procedure. The apparatus receives, from a base station, random access configuration information for the base station. The apparatus determines a first time duration for a preamble of a first random access message based on the random access configuration information received from the base station and a reference SCS associated with an uplink BWP configured for the first random access message. The apparatus determines a second time duration for a payload of the first random access message based on the random access configuration information received from the base station and the reference SCS. The apparatus transmits the first message to the base station to initiate a random access procedure.
