Abstract: The disclosure of the present specification provides a method for receiving a physical downlink shared channel (PDSCH) on a low-capability (LC) or low-cost (LC) device. The method may comprise the steps of: receiving repetition of a downlink control channel in the case that the LC device is set to coverage enhancement (CE); determining a last subframe where the reception is terminated; and determining a start subframe for receiving the repetition of the PDSCH on the basis of the last subframe. The reception of the PDSCH starts at the k-th effective subframe after subframe n, and the subframe n may be the last subframe where the reception of the downlink control channel is terminated. K is greater than or equal to 2, and the effective subframe may be predetermined.

Abstract: A search space for a user equipment can be set over a plurality of subframes. The starting positions of the starting subframe of the search space and a control channel for the user equipment may be different. The start of the search space is limited to a set of specific subframes. The search space may occur cyclically. The cycle of the search space is prefixed, or may be set for the user equipment by means of system information or an upper layer signal.

Abstract: Provided are a method and a device whereby a synchronization signal is transmitted and received. One embodiment of the present invention involves using one of a plurality of cells (first cell hereinbelow) in order to transmit synchronization signal setting information of a cell (second cell hereinbelow) set in an unlicensed band of the plurality of cells. The synchronization signal is transmitted on the second cell, based on the synchronization signal setting information. The synchronization signal is used in order to acquire time and frequency synchronization with the second cell.

Abstract: Disclosed herein is a method and apparatus for transmitting/receiving a signal in a wireless communication system supporting NB-IoT. An eNB provides a user equipment (UE), for which NB-IoT is not configured, with information about frequency bands (anchor RBs) possibly having a synchronization signal for NB-IoT (hereinafter, an NB-IoT SS). When the eNB transmits a downlink signal to the UE, it may puncture the downlink signal on an RB having the NB-IoT SS, based on the information. When the UE transmits an uplink signal, it may puncture the uplink signal on an RB having the NB-IoT SS, based on the information.

Abstract: In one disclosure of the present invention, a method is provided for receiving an enhanced physical downlink control channel (EPDCCH) from a small cell having low transmission power. The receiving method may comprise the steps of: receiving EPDCCH-PRB set information including information about a physical resource block (PRB) that will receive the EPDCCH from the small cell; and determining a subframe that will be received by the EPDCCH from the small cell on the PRB checked by the EPDCCH-PRB set information. Here, the subframe that may be received by the EPDCCH from the small cell may be determined so as not to overlap a subframe transmitted by the EPDCCH by means of one or a plurality of neighboring cells.
