Claim 14:
15. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a network, information for a number of repetitions of one or more first resource units and information for a number of repetitions of one or more second resource units;
transmitting, to the network, uplink (UL) data using the one or more first resource units repetitively by the number of repetitions of the one or more first resource units; and
transmitting, to the network, an acknowledgement/negative-acknowledgement (ACK/NACK) signal using the one or more second resource units repetitively by the number of repetitions of the one or more second resource units,
wherein each of the one or more first resource units consists of a first number of resource elements (REs) within one or more subcarriers in frequency domain and a first time interval in time domain,
wherein each of the one or more second resource units consists of a second number of REs within a single subcarrier in frequency domain and a second time interval in time domain, and
wherein the second number of REs is smaller than the first number of REs.
