Abstract

A mobile communication method according to the present invention, includes the steps of: (A) assigning a radio resource for a PRACH in each cell within a mobile communication system in which cells are synchronized; and (B) performing, at a mobile station (UE), a random access procedure by transmitting an RA preamble via the PRACH using the radio resource assigned in each cell, wherein in the step (A), as the radio resource for a PRACH, a resource block in a different sub-frame is assigned between adjacent cells.
