Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a random access method which establishes an individual channel between a radio communication terminal device and a base station device in a short time a transmitter a receiving method and a receiver.

SOLUTION: A radio communication terminal device has: an allocation unit 210 including RACH sub-channel allocation units 211; and a replication unit 202. In a step ST320 the RACH sub-channel allocation unit allocates a transmission packet input from the replication unit to an arbitrary sub-carrier at the RACH arbitrary time slot at random. In a step ST330 the allocation unit determines whether overlap is generated in an allocation result obtained by the RACH sub-channel allocation unit 211. When the allocation unit 210 determines that the overlap is generated in the allocation result the allocation unit 210 makes either of the RACH sub-channel allocation units 211 which has generated the overlap perform once again the allocation of the step ST320. On the other hand when it is determined that no overlap is generated in the allocation result a step ST340 is executed.
