<P>PROBLEM TO BE SOLVED: To provide a contention sensing method and a device between random access (RA) procedure in a mobile communication system. <P>SOLUTION: A layer 2 or a layer 3 (L2/L3) message is received from a terminal, through an uplink resource allocated to the terminal by a RA preamble response message transmitted for a random access procedure started from the terminal. If the L2/L3 message is an initial access message, a contention cancellation (CR) message associated with the RA procedure is transmitted to the terminal, whereas if the L2/L3 message is not an initial access message, predetermined control information is transmitted to the terminal through a downlink control channel, without transmission of the CR message. <P>COPYRIGHT: (C)2013,JPO&INPIT |
