1. A method for selecting a Modulation Coding Scheme (MCS) in a wireless communication system, the method comprising:
receiving, by a User Equipment (UE), at least one fallback/advance MCS value for each Hybrid Automatic Repeat and request (HARM) process;
receiving, by the UE, a list of default MCS in an uplink (UL) grant from a base station;
measuring, by the UE, a channel condition including a Channel Quality Indicator (CQI); and
in case that the channel condition is insufficient to use the default MCS provided in the UL grant, using MCS among the at least one fallback/advance MCS value; and
indicating the used MCS to the base station via a physical uplink shared channel (PUSCH) transmission using uplink control information (UCI).
