Method for transmitting and receiving uplink signal for NB-IoT UE and apparatus therefor

Abstract:

Provided are a method and apparatus for transmitting an uplink signal by a Narrow Band Internet of things (IoT) UE. The method may include receiving, from a base station, uplink resource allocation information for transmitting HARQ ACK/NACK for downlink data, configuring a time-axis wireless resource and a frequency-axis wireless resource of an uplink signal including the HARQ ACK/NACK, based on the uplink resource allocation information, and transmitting the uplink signal through the time-axis wireless resource and frequency-axis wireless resource.
