Abstract: Disclosed is a method for a wireless device for transmitting a random-access preamble. The method may comprise the steps of: generating a sequence of a random-access preamble; and mapping the sequence of a random-access preamble to one sub-carrier wave from among 12 sub-carrier waves of a frequency domain. The mapping step may comprise the step for carrying out a first hop between a plurality of sub-regions. Each sub-region may comprise a previously set number of sub-carrier waves. The mapping step may additionally comprise the step for carrying out a second hop from among the sub-carrier waves within any one sub-region.

Abstract: A method for transmitting a random access preamble in a narrowband-IoT system supporting time division duplexing and an apparatus therefor. In some implementations, a method for transmitting a narrowband physical random access channel (NPRACH) preamble by a user equipment in a narrowband-Internet of things (NB-IoT) system supporting time division duplexing may include: receiving, from a base station, configuration information related to an uplink-downlink configuration; and transmitting, to the base station, the NPRACH preamble configured by considering the uplink-downlink configuration.

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.

Abstract: The disclosure of the present specification provides a method for performing a narrowband physical uplink shared channel (NPUSCH) transmission. The method may comprise: determining a start position of the NPUSCH transmission; performing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a first of two contiguous subframes; and postponing the NPUSCH transmission, if the start position of the NPUSCH transmission is determined as a second of the two contiguous subframes. The two contiguous subframes may be configured as a time division duplex (TDD) uplink subframe based on at least one of TDD configurations 1 and 4. The two contiguous subframes may be defined for a subcarrier spacing of 3.75 kHz.

Abstract: A disclosure of the present specification provides a method for receiving a control channel in a search space. The method may comprise the steps of: determining an order of multiple search spaces in a blind decoding; and performing the blind decoding in the multiple search spaces according to the determined order. In this regard, the order of the multiple search spaces may be determined on the basis of delay sensitivity.

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).
