1. An integrated circuit to control a process, the process comprising:receiving control information and transmission data, the control information including a MCS (Modulation and Coding Scheme) and RV (Redundancy Version) information indicating a RV parameter, and the RV parameter indicating a start position of the transmission data in data that is encoded;
determining the RV parameter based on a number of bits of the RV information; and
decoding the received transmission data based on the MCS and the RV parameter,
the number of bits of the RV information is set according to a granularity of control;
when the number of bits of the RV information is set to two, the RV parameter is determined as any one among 0, 1, 2 and 3; and
when the number of bits of the RV information is set to zero, the control information includes no RV information and the RV parameter is determined as 0.
