Abstract  Abstract

Disclosed are a random access method for establishing a separate channel between a wireless communication terminal device and a base station device in a short time, and a wireless communication terminal device for executing the random access method. In this apparatus, in step ST 320, the RACH subchannel allocator 211 randomly allocates a transmission packet input from the copy unit 202 to any time slot of the RACH as an arbitrary subcarrier. In step ST 330, the allocator 210 determines whether duplication has occurred in the allocation result by the RACH subchannel allocator 211. If the allocation unit 210 determines that duplication has occurred in this allocation result, the allocation unit 210 assigns any of the RACH subchannel allocation units 211 that generated the duplication again in step ST 320. To do this. On the other hand, if it is determined that duplication has not occurred in the assignment result, step ST 340 is executed.
