1. An operation method of a first terminal in a communication system, the operation method comprising:
receiving a high layer signal configuring an additional modulation and coding scheme (MCS) table;
generating first sidelink control information (SCI) including an additional MCS table indicator indicating one of the additional MCS table or an existing MCS table, and an MCS index indicating one MCS in an MCS table indicated by the additional MCS table indicator;
transmitting, to a second terminal, the first SCI on a physical sidelink control channel (PSCCH);
performing a coding operation and a modulation operation on first data based on the additional MCS table indicator and the MCS index; and
transmitting, to the second terminal, the first data on a physical sidelink shared channel (PSSCH),
wherein the first SCI further includes an information element indicating a total number transmissions of same data without reception of a hybrid automatic repeat request (HARQ) response.
