Patent ID: 11949502
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An electronic device, comprising:
at least one communication circuit configured to support wireless communication with a base station;
a memory configured to store at least two modulation and coding scheme (MCS) index tables; and
a processor operatively connected to the communication circuit and the memory, wherein the processor is configured to:
receive retransmitted downlink control information (DCI) including a retransmission MCS index from the base station using the communication circuit when a cyclic redundancy check (CRC) failure occurs,
compare the retransmission MCS index with the retransmission MCS index stored in the memory based on the retransmission MCS index of the DCI,
determine a mismatch in the MCS index tables based on determining that the retransmission MCS indexes are different, and
recover the MCS index tables based on determining the mismatch in the MCS index tables.
