ABSTRACT:
The present invention relates to a method for data transmission in a communication system. The method including, determining, at the transmitter, whether to transmit data signal using a single codeword or two codewords, when it is determined that the single codeword transmission is used, coding, by the transmitter, a control signal by using a first signal format, with the control signal coded by the first signal format carrying information regarding the single codeword, when it is determined that the two codewords transmission is used, coding, by the transmitter, the control signal by using a second signal format, with the control signal coded by the second signal format carrying information regarding both of the two codewords, transmitting the data signal and the control signal according to the determined transmission format from the transmitter to the receiver.
