Classification: CPC H  Y | IPC H

Claim 13:
14. A network node in a wireless communication system, the NB-IoT UE comprising:
a memory;
a transceiver; and
at least one processor, coupled to the memory and the transceiver, the processor configured to:
control the transceiver to transmit, to a user equipment (UE), 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;
control the transceiver to receive, from the UE, uplink (UL) data on the one or more first resource units repetitively used by the number of repetitions of the one or more first resource units; and
control the transceiver to receive, from the UE, an acknowledgement/negative-acknowledgement (ACK/NACK) signal on the one or more second resource units repetitively used by the number of repetition 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.
