Method and device for configuring resource unit for transmitting uplink signal by NB-IoT UE

Abstract:

Provided is a method for transmitting an uplink signal by a NarrowBand IoT (Internet of Things) UE and a device therefor. The method may include: receiving downlink data from a base station; generating HARQ ACK/NACK feedback information related to the downlink data; and transmitting the HARQ ACK/NACK feedback information to the base station through a Narrowband Physical Uplink Shared Channel (NPUSCH), wherein the NPUSCH is mapped to a resource unit configured by M subcarriers and K slots.
