Abstract: A base station receives uplink data and a first demodulation reference signal (DMRS) in a physical multiple access (MA) resource, and attempts to decode the uplink data, using the first DMRS. When the base station fails to decode the uplink data, the base station transmits an ACK/NACK for a first MA signature corresponding to the first DMRS among multiple MA signatures. When the ACK/NACK for the first MA signature is a NACK and the received power level of the first DMRS is higher than or equal to a threshold, the base station transmits a MA signature reselection command for the first MA signature together with the ACK/NACK. When the ACK/NACK for the first MA signature is a NACK and the received power level of the first DMRS is lower than the threshold, the base station transmits a MA signature maintenance command for the first MA signature together with the ACK/NACK.

Abstract: Provided are a method for transmitting uplink control information (UCI) of a terminal in a wireless communication system and the UE using the method. The method includes determining a number of coded symbols for the UCI transmission and transmitting the UCI on a physical uplink shared channel (PUSCH) based on the number of coded symbols. The number of coded symbols is determined among a first value based on a payload size of the UCI and an offset value and a second value based on a radio resource control (RRC) signal.
