Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor configured to:
transmit, via the transceiver, a random access (RA) preamble,
monitor 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),
identify information associated with a system frame number (SFN) included in the DCI with CRC scrambled by the RA-RNTI,
receive, via the transceiver, 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,
identify 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,
determine 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
decode the RAR based on the determination.
