Abstract  Abstract

A random access method for establishing a dedicated channel between a radio communication terminal apparatus and a base station apparatus in a short period of time and a radio communication terminal apparatus that executes this random access method are disclosed. In this apparatus, in step ST320, the RACH subchannel allocation unit (211) randomly allocates the transmission packet input from the duplication unit (202) to an arbitrary subcarrier in an arbitrary RACH time slot. In Step ST330, the allocation unit (210) determines whether or not there is an overlap in the allocation result by the RACH subchannel allocation unit (211). If the allocation unit (210) determines that there is an overlap in the allocation result, either the RACH subchannel allocation unit (211) in which the allocation unit (210) has generated the overlap, The allocation in step ST320 is performed again. On the other hand, when it is determined that there is no duplication in the allocation result, step ST340 is executed.
