1. A method of operating a user equipment (UE) in a wireless communication system, the method comprising:
receiving a reference signal from a base station;
generating channel information based on the reference signal;
transmitting the channel information to the base station;
receiving a signal including a channel-coded transport block according to at least one coding rate and modulation order determined based on the channel information;
obtaining a first part of the channel-coded transport block by detecting a transmit antenna combination (TAC); and
obtaining a second part of the channel-coded transport block by demodulating modulation symbols of the signal,
wherein the channel information comprises first information related to first channel quality for the TAC, second information related to second channel quality for the modulation symbols, and third information related to third channel quality for modulation symbols which are affected by a TAC detection error.
