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.

A method for transmitting an uplink signal by a NarrowBand Internet of things (IoT) user equipment (UE) comprising:
- receiving downlink data from a base station;
- generating hybrid automatic repeat request (HARQ) ACK/NACK feedback information related to the downlink data;
- and
- transmitting the HARQ ACK/NACK feedback information to the base station through a resource unit of a NarrowBand Physical Uplink Shared Channel (NPUSCH),
- wherein the resource unit of the NPUSCH is made up of M subcarriers and K slots, where K is determined as 2n where M and n are natural numbers,
- wherein the NarrowBand IoT UE is configured to have one of a first subcarrier spacing and a second subcarrier spacing, and
- wherein when HARQ ACK/NACK feedback information is transmitted through the NPUSCH, values of M and K when the NarrowBand IoT UE is configured to have the first subcarrier spacing are the same as values of M and K when the NarrowBand IoT UE is configured to have the second subcarrier spacing.
A method for receiving an uplink signal by a base station, comprising:
- transmitting downlink data to a NarrowBand IoT (Internet of Things) user equipment (UE);
- and
- receiving hybrid automatic repeat request (HARQ) ACK/NACK feedback information related to the downlink data through a resource unit of a Narrowband Physical Uplink Shared Channel (NPUSCH)
- wherein the resource unit of the NPUSCH is made up of M subcarriers and K slots, where K is determined as 2n where M and n are natural numbers,
- wherein the NarrowBand IoT UE is configured to have one of a first subcarrier spacing and a second subcarrier spacing, and
- wherein when HARQ ACK/NACK feedback information is transmitted through the NPUSCH, values of M and K when the NarrowBand IoT UE is configured to have the first subcarrier spacing are the same as values of M and K when the NarrowBand IoT UE is configured to have the second subcarrier spacing.
A NarrowBand Internet of things (IoT) user equipment (UE) for transmitting an uplink signal, the NarrowBand IoT UE comprising:
- a receiver configured to receive downlink data from a base station;
- a controller configured to generate hybrid automatic repeat request (HARQ) ACK/NACK feedback information related to the downlink data;
- and
- a transmitter configured to transmit the HARQ ACK/NACK feedback information to the base station through a resource unit of a Narrowband Physical Uplink Shared Channel (NPUSCH),
- wherein the resource unit of the NPUSCH is made up of M subcarriers and K slots, where K is determined as 2n where M and n are natural numbers,
- wherein the NarrowBand IoT UE is configured to have one of a first subcarrier spacing and a second subcarrier spacing, and
- wherein when HARQ ACK/NACK feedback information is transmitted through the NPUSCH, values of M and K when the NarrowBand IoT UE is configured to have the first subcarrier spacing are the same as values of M and K when the NarrowBand IoT UE is configured to have the second subcarrier spacing.
