RANDOM ACCESS METHOD OF A TERMINAL CAPABLE OF REDUCING A RANDOM ACCESS PROCEDURE IN A MOBILE COMMUNICATION SYSTEM

摘要

PURPOSE: A random access method of a terminal is provided to simplify random access operation implementation and to reduce a random access procedure in a mobile communication system.;CONSTITUTION: A UE(User Equipment) receives a first random access response message including a back-off indicator through a first DL CC(Component Carrier) having a first UL CC as a response to a first random access preamble(S502). The UE applies a back-off period in consideration of a back-off indicator which is received through the first random access response message. The UE transmits a second random access preamble to an eNB through a second UL CC.;COPYRIGHT KIPO 2012
