Abstract: Disclosed are a method for channel estimation in a wireless communication system, and a device therefor. Particularly, the method for estimating a channel by a terminal in a wireless communication comprises the steps for: receiving, from a base station, configuration information for channel estimation, the configuration information comprising relationship information related to the relationship between a cell-specific reference signal (CRS) and a demodulation-reference signal (DM-RS); receiving the CRS from the base station; receiving, from the base station, on a specific channel, the DM-RS and machine type communication (MTC) control information; estimating the specific channel by using the CRS and DM-RS, on the basis of the relationship information; and decoding the MTC control information via the estimated specific channel, wherein the relationship information comprises information about a pre-coding relationship between the CRS and DM-RS, and power ratio information of the CRS with respect to the DM-RS, and the power ratio information is information related to the power ratio between a CRS port and DM-RS port for an idle mode.

Abstract: Disclosed is a method of transmitting a physical uplink control channel (PUCCH) by a user equipment (UE) in a wireless communication system. The method includes receiving information related to an index of a PUCCH resource set for the PUCCH and to the number of resource blocks (RBs) for the PUCCH, and transmitting the PUCCH through a PUCCH resource based on a first RB offset. A second RB offset of the PUCCH resource set is obtained based on the index, and the first RB offset is obtained by multiplying the number of RBs by the second RB offset.
