METHOD AND APPARATUS FOR TRANSMITIING ACK/NACK

Abstract: a technology enabling a terminal to receive acknowledgement (ack)/negative ack (nack) information about data transmitted from the terminal is provided. the method includes receiving cyclic shift information for a reference signal from the base station; transmitting, to the base station, the data and a reference signal which is cyclic-shifted using a cyclic shift value, the cyclic shift value being determined based on a dynamic cyclic shift value mapped one-to-one to the cyclic shift information for the reference signal; and receiving, from the base station, the ack/nack information about the transmitted data through a radio resource of a downlink channel, the radio resource of the downlink channel being identified based on a modifier mapped one-to-one to the cyclic shift information for the reference signal.
