- Provided are a random access method of a mobile station and a mobile communication device performing the same. The mobile station can obtain a diversity gain without a Random Access Channel (RACH) burst collision by hopping according to a cell group in a frequency domain and transmitting a random access when random access resources are used between neighboring cells and detect an RACH even with low transmission power by applying switching diversity together with the frequency hopping.
