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 including cyclic shift values selected from only an unrestricted set; and
transmitting the generated RACH preamble based on the synchronization signal and the broadcast channel signal.
