Abstract: According to the present invention, a downlink control channel can be transmitted in varied numbers of OFDM symbols. The downlink control channel can be transmitted in a first number of OFDM symbols or can be transmitted in a second number of OFDM symbols. A user equipment can monitor a first downlink control channel candidate that spans the first number of OFDM symbols and can monitor a second downlink control channel candidate that spans the second number of OFDM symbols in a transmission time interval (TTI) for the reception of the downlink control channel. The downlink control channel can be transmitted by means of one or more control channel elements (CCE), each CCE comprising resources in the same OFDM symbol.

Abstract: The present invention provides: a base station for repeatedly transmitting a physical downlink control channel (PDCCH) during a first subframe bundle comprising a plurality of subframes, and transmitting a PDSCH related to the PDCCH; and user equipment for receiving the PDCCH and the PDSCH. The PDSCH can be transmitted to the user equipment starting from subframe n+k, which is the kth subframe after the last subframe n−1 in the first subframe bundle, wherein k is an integer bigger than 0. The first subframe bundle may begin from a predetermined or fixed position.

Abstract: Provided are method and device for transmitting/receiving a downlink signal. A user equipment-specific reference signal (UE-RS) can be transmitted to a user equipment. A downlink control channel and a downlink data channel for the user equipment can share the UE-RS. Antenna port information about a transmission antenna port of the downlink control channel and/or a transmission antenna port of the downlink data channel is provided to the user equipment. The user equipment receives UE-RS(s) corresponding to the antenna port information and thus receives the downlink control channel and the downlink data channel.

Abstract: The disclosure of the present specification provides a method for receiving a physical downlink shared channel (PDSCH) in a low-capability (LC) or low-cost (LC) device. The method may comprise: a step for receiving repetition of a downlink control channel when coverage enhancement (CE) is set on the LC device; a step for determining multiple subframes to receive the repetition of the PDSCH on the basis of the reception of the repetition of the downlink control channel; a step for assessing whether or not a gap subframe exists among the multiple subframes; and a step for dropping the reception of the PDSCH on the gap subframe.

Abstract: Discussed is a method for transmitting a discovery signal. The method is performed by a cell of a base station and includes transmitting, to a user equipment (UE), measurement configuration information including a sub-frame offset, wherein the sub-frame offset indicates an offset between a secondary synchronization signal (SSS) and a channel-state information reference signal (CSI-RS) in a discovery signal; transmitting the SSS in the discovery signal on a first sub-frame; and transmitting the CSI-RS on a second sub-frame which is determined based on the sub-frame offset and the first sub-frame for the SSS in the discovery signal.
