Abstract: The present specification discloses a transmission/reception method for a machine type communication (MTC) apparatus. The transmission/reception method for the MTC apparatus may comprise the steps of: receiving, by the MTC apparatus, setting information about a multicast-broadcast single-frequency network (MBSFN) subframe from a base station; receiving, by the MTC apparatus, downlink data for the MTC apparatus, on a data region of the MBSFN subframe; and receiving, by the MTC apparatus, a cell-specific reference signal (CRS) only on a portion of the resource blocks (RBs) in the whole system bandwidth of the data region in the MBSFN subframe. Here, the CRS received only on the portion of RBs may be transmitted while electric power is increased by means of the base station.

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.
