Classification: CPC H | IPC H

Claim 10:
11. A method of operating an electronic device, the method comprising:
receiving, when a cyclic redundancy check (CRC) failure occurs, retransmitted downlink control information (DCI) including a retransmission modulation and coding scheme (MCS) index from a base station using a communication circuit;
comparing the retransmission MCS index with a retransmission MCS index stored in a memory based on the retransmission MCS index of the DCI;
determining a mismatch in MCS index tables based on determining that the retransmission MCS indexes are different; and
restoring the MCS index tables based on determining the mismatch in the MCS index tables.
