Abstract: A method for determining a transport block size includes including determining a number of physical resource blocks (PRBs) based on a value smaller than a total number of PRBs allocated for a physical downlink shared channel (PDSCH), based on that the device is a first device and based on that the PDSCH is to be received on a time division duplex (TDD)-based special subframe, determining the number of PRBs to be the same as the total number of PRBs allocated for the PDSCH, based on that the device is a second device, which is related to a low-complexity device or which is configured for a coverage enhancement (CE), and determining the transport block size in the PDSCH based on the determined number of PRBs.

Abstract: A method for transmitting a physical uplink shared channel (PUSCH) is discussed. The method is performed by a wireless device and includes receiving downlink control information (DCI), which is repeated on a plurality of downlink subframes, identifying a last subframe on which the repetition is completed, determining that the identified last subframe is not used for determining a start subframe to repeatedly transmit the PUSCH, substituting the last subframe with a first subframe usable for determining the start subframe to transmit the PUSCH after the identified last subframe, based on the determination that the identified last subframe is not used for determining the start subframe; determining the start subframe to transmit the PUSCH, based on the first subframe other than the last subframe, and transmitting the PUSCH repeated over a plurality of subframes starting from the determined start subframe.

Abstract: Disclosed is a method for a terminal to transmit an uplink data signal in a narrowband wireless communication system. Specifically, the method comprises the steps of: receiving, from a base station, a downlink control signal including resource allocation information for resource blocks continuously allocated for the uplink data signal within allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein the continuously allocated resource blocks are updated to include a center resource block, when the allocable resource blocks include the center resource block of a system bandwidth.

Abstract: A user equipment is provided with puncturing information indicating a resource to which downlink data is punctured among time-frequency resources to which the downlink data is allocated. The user equipment may decode the downlink data received in the time-frequency resource on the basis of the puncturing information. The downlink data may be mapped to the time-frequency resource by a combined method of a time-first resource mapping method and a frequency-first resource mapping method, or by a distributed resource mapping method.

Abstract: A method and apparatus for handling overlap of multiple channels in a wireless communication system is provided. A user equipment (UE), which operates in half-duplex frequency division duplex (FDD), determines that a periodic uplink (UL) transmission collides with a physical downlink shared channel (PDSCH) reception in a subframe, and performs either the periodic UL transmission or the PDSCH reception in the subframe. When the periodic UL transmission corresponds to a semi-persistent scheduled (SPS) physical uplink shared channel (PUSCH), the PDSCH reception is performed.

Abstract: A method for downlink control information (DCI) transmission/reception is provided. The method for DCI transmission comprises: receiving, by a user equipment, a narrowband physical downlink control channel (N-PDCCH) carrying the DCI. The N-PDCCH is received using at least one of two control channel element (CCEs) on the 1 resource block (RB) only. A first CCE of the two CCEs occupies 6 subcarriers of the lowest indices among the 12 subcarriers and a second CCE of the two CCEs occupies 6 subcarriers of the highest indices among the 12 subcarriers.
