Abstract: Provided are a user equipment configured to be operated within a particular predetermined band smaller than the entire system band and a base station supporting the user equipment. A reference signal and a downlink control channel on the basis of the reference signal are transmitted to the user equipment within the particular band in a subframe. The downlink control channel is transmitted within one or more orthogonal frequency division multiplexing (OFDM) symbols except a predetermined number of leading OFDM symbols among OFDM symbols in the subframe. The reference signal is transmitted in at least one of the one or more OFDM symbols.

Abstract: Information indicating one of possible PDSCH start subframes may be provided to the UE via the PDCCH. The PDSCH corresponding to the PDCCH may be transmitted/received starting from the indicated subframe. The possible PDSCH start subframes may be determined based on the ratio of the maximum number of PDCCH repetitions in the PDCCH search space and may be determined based on the ratio of the number of times related to the PDSCH repetition after the PDCCH search space.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.

Abstract: A method for performing a measurement in a wireless communication system and an apparatus for the same are disclosed. Particularly, a method by which a terminal performs a measurement in a wireless communication system comprises the steps of: receiving, by the terminal, a discovery signal; and measuring, by the terminal, reference signal received power (RSRP) and/or reference signal received quality (RSRQ) on the basis of the discovery signal, wherein the number of antenna ports of a cell-specific reference signal (CRS) cannot be applied to the discovery signal-based measurement.
