Abstract  Abstract

A method for performing a random access procedure in a mobile communication system the method comprising:
receiving a first message including a random access preamble;
transmitting a second message which is a random access response message in response to the first message;
determining whether or not a third message including a Cell-Radio Network Temporary Identifier (C-RNTI) is received from a User Equipment (UE);
transmitting a fourth message which is a Contention Resolution (CR) message for the random access procedure to the UE upon receipt of the third message that does not include the C-RNTI from the UE; and
transmitting UE-specific control information to the UE upon receipt of the third message including the C-RNTI from the UE
wherein the UE-specific control information includes a Cyclic Redundancy Check (CRC) specifically mapped to the C-RNTI of the UE and
wherein the first second third and fourth messages occur in a random access procedure in a mobile communication system.
