Abstract

Provided is a method of a terminal in a wireless communication system, including receiving DCI for scheduling PUSCH transmission; determining a number of modulation symbols per layer for transmission of UCI based on a number of code blocks associated with a UL-SCH, C UL-SCH , a value K r for an r-th code block of the code blocks and a number of bits of the UCI, O ACK , wherein in case that the DCI includes CBGTI and the CBGTI indicates that the r-th code block associated with the UL-SCH of the PUSCH transmission is not for transmission, the value K r for the UCI is determined as 0, and else, the value K r for the UCI is determined as a size of the r-th code block for the UL-SCH of the PUSCH transmission; and transmitting, to a base station, the UCI on the PUSCH based on the number of modulation symbols per layer.
