Abstract:
A method and apparatus for transmitting a physical uplink shared channel (PUSCH) and a demodulation reference signal (DM-RS) in a wireless communication system is provided. A narrowband internet-of-things (NB-IoT) user equipment (UE) configures a set of resource units with at least one tone for uplink transmission in NB-IoT, transmits the PUSCH by using the set of resource units, and transmits the DM-RS used for demodulating the PUSCH by a network in the set of resource units.
