Abstract: Provided are a method for supporting a variable bandwidth and an apparatus using the same. In the apparatus, a wireless device receives a synchronization signal in a first bandwidth, and acquires a second bandwidth for a downlink (DL) channel on the basis of the synchronization signal. The apparatus receives the DL channel in the second bandwidth.

Abstract: One disclosure of the present application provides a method for a narrowband (NB) wireless device to determine whether or not to transmit a scheduling request (SR). The method may comprise a step of determining whether or not to transmit an SR by using a resource for the transmission of a hybrid automatic retransmit request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) signal. The step of determination may be performed if one or more HARQ processes are run. The resource for the HARQ ACK/NACK signal may include a narrowband physical uplink shared channel (NPUSCH).

Abstract: This specification provides a method for performing early data transmission in a random access procedure in a wireless communication system.More specifically, the method performed by a user equipment (UE) includes: receiving, from a base station, a control message including first information indicating whether selection for a second transport size (TBS) smaller than a first TBS for message 3 is permitted and second information for the first TBS; transmitting, to the base station, a request for the EDT by using message 1; receiving, from the base station, message 2 including a UL grant for the message 3; determining a repetition number for the message 3 based on the control message and the UL grant; and transmitting the message 3 to the base station by the repetition number.Therefore, there is an effect that battery consumption of the UE can be reduced.
