First Claim
1. A method for performing a fast initial access procedure in a wireless access system supporting an ultrahigh frequency band, the method comprising:
- receiving a synchronization signal;
receiving a broadcast channel signal;
generating a Random Access Channel (RACH) preamble using prefixed Physical Random Access Channel (PRACH) parameters according to a small cell supported in the ultrahigh frequency band; and
transmitting the generated RACH preamble based on the synchronization signal and the broadcast channel signal.

Abstract
The present invention provides a method for performing an initial access process used in a wireless access system and in an ultrahigh frequency band, and devices supporting same. The method for performing a high-speed initial access process in a wireless access system supporting an ultrahigh frequency band, according to one embodiment of the present invention, may comprise the steps of: receiving a synchronizing signal; receiving a broadcast channel signal; generating a random access preamble by using pre-fixed physical random access parameters according to a small cell supported in the ultrahigh frequency band; and transmitting the generated random access preamble on the basis of the synchronizing signal and the broadcast channel signal.
