Claim 0:
1. A method performed by a terminal in a wireless communication system, the method comprising:
transmitting a random access (RA) preamble;
monitoring physical downlink control channel (PDCCH) including downlink control information (DCI) with cyclic redundancy check (CRC) scrambled by a RA-radio network temporary identifier (RNTI) (RA-RNTI);
identifying information associated with a system frame number (SFN) included in the DCI with CRC scrambled by the RA-RNTI;
receiving a random access response (RAR) in a RAR window based on the information associated with the SFN included in DCI with CRC scrambled by the RA-RNTI;
identifying whether the information associated with the SFN included in the DCI with CRC scrambled by the RA-RNTI corresponds to information associated with a SFN of a system frame in which the RA preamble is transmitted;
determining to decode the RAR in case that the information associated with the SFN included in the DCI with CRC scrambled by the RA-RNTI corresponds to the information associated with the SFN of the system frame in which the RA preamble is transmitted; and
decoding the RAR based on the determination.
