NB-IoT Methods for transmitting and receiving uplink signals for NarrowBand-IoT UE and Apparatuses thereof

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an uplink transmission and reception technique of a NarrowBand Internet of Things (NB-IoT) terminal in a 3GPP LTE / LTE-Advanced system. Specifically, the present invention relates to a specific procedure for transmitting an HARQ ACK / NACK of an NB-IoT terminal transmitting and receiving data using narrowband and a technique for setting transmission resources. In particular, the present invention provides a method for transmitting an uplink signal by a NarrowBand IoT (Internet of things) terminal, comprising: receiving uplink resource allocation information for transmitting HARQ ACK / NACK for downlink data from a base station; Setting up a time base radio resource and a frequency axis radio resource of an uplink signal including HARQ ACK / NACK based on link resource allocation information, and transmitting an uplink signal in a time base radio resource and a frequency axis radio resource, Method and apparatus.
