METHOD AND APPARATUS FOR DETECTING CONTENTION DURING RANDOM ACCESS PROCEDURE IN A MOBILE COMMUNICATION SYSTEM

摘要

A method and apparatus for detecting contention in an RA procedure in a m obile communication system is provided in which an L2/L3 message is received from a UE in uplink resources allocated to the UE by an RA preamble respons e message that was transmitted for an RA procedure initiated by the UE, a CR message associated the RA procedure is transmitted to the UE, if the L2/L3 message is an initial access message, and predetermined control information is transmitted to the UE on a downlink control channel without transmitting the CR message, if the L2/L3 message is not an initial access message.
