RANDOM ACCESS METHOD FOR AN OBJECT COMMUNICATION SERVICE AND A WIRELESS COMMUNICATION DEVICE THEREOF CAPABLE OF MINIMIZING COLLISION WITH A GENERAL TERMINAL WHEN AN MTC DEVICE PERFORMS RANDOM ACCESS PROCESS IN A 3GPP LTE-ADVANCED SYSTEM

摘要

PURPOSE: A random access method for an object communication service and a wireless communication device thereof are provided to add a random access preamble group for an MTC device into system information.;CONSTITUTION: A base station inserts a random access preamble group field for MTC(Machine Type Communication) device into an SIB 2(System Information Block Type 2)(S501). The base station inserts an MTC random access time IE(Information Element) into an SIB(S502). The MTC device extracts random access preamble group information for MTC device from the SIB 2(S504). The MTC device transmits the random access preamble(S505).;COPYRIGHT KIPO 2012
