Abstract
In a system supporting narrowband Internet of things (NB-IoT), a terminal maps an uplink reference signal to a plurality of resource elements in a scheduled resource allocation unit, and transmits the uplink reference signal mapped to the plurality of resource elements. Here, the scheduled resource allocation unit includes a first number of contiguous slots in a time domain and a second number of contiguous subcarriers in a frequency domain.
