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: A method and apparatus for forming a resource block (RB) structure in a wireless communication system is provided. A user equipment (UE) receives a downlink (DL) signal via first physical resource blocks (PRBs), which are indexed by a network from a center of a band or from a center of a carrier, from the network. And, the UE transmits an uplink (UL) signal via second PRBs, which are aligned with the first PRBs according to synchronization signal (SS) blocks, to the network. Accordingly, a global PRB indexing and a local PRB indexing can be aligned with each other.

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.
