Abstract

Provided is a method of transmitting scheduling control information on a physical uplink shared channel by a base station. The method includes transmitting control information indicating a specific modulation and coding scheme (MCS) index corresponding to modulation and coding scheme (MCS) information to be applied to the physical uplink shared channel through a physical downlink control channel, and receiving the physical uplink shared channel modulated based on specific MCS information determined using one of two or more MCS tables containing the specific MCS index and modulation order information corresponding to at least the MCS index.
