Abstract: Provided is a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate only in a part of a band among system bands of a cell. A method for receiving a downlink control channel can comprise the steps of: determining a precoding matrix index (PMI) applied to a downlink control channel receivable only in a part of a band; receiving from a cell the downlink control channel in the part of the band in a data area of a subframe; and decoding the downlink control channel, which has been received from the cell, on the basis of the determined PMI.

Abstract: The present disclosure provides a method for receiving a physical downlink shared channel (PDSCH), the method being performed by a wireless device. The method may comprise the steps of determining the number of physical resource blocks (PRBs); and determining a transport block size (TBS) within the PDSCH on the basis of the determined number of the PRBs, wherein when the wireless device is an LC device or when the wireless device is set to CE so that the PDSCH is repeatedly received on a plurality of subframes, the number of PRBs used for determining the TBS can be calculated to be the same as the total number of PRBs that have been actually allocated for the PDSCH, regardless of whether the PDSCH is received in a TDD special subframe.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel, which is repeated on a plurality of downlink subframes, by a wireless device in a wireless communication system. The method may comprise the steps of: attempting, by the wireless device, blind decoding of the downlink control channel, using one or more of multiple scrambling codes; when the blind decoding is successful, determining, by the wireless device, a repetition level for the downlink control channel on the basis of a scrambling code by which the wireless device has been successful in the blind decoding; and determining, by the wireless device, the number of repetitions of the downlink control channel according to the repetition level.

Abstract: The present invention determines a PUCCH resource based on which serving cell ACK/NACK information is related to, when a user device set as a plurality of serving cells transmits the ACK/NACK information. Moreover, if a PUCCH transmission time matches with a PUSCH transmission time, the present invention does not piggy back ACK/NACK information to PUSCH but transmits the ACK/NACK information through PUCCH.

Abstract: A disclosure of the present specification provides a method for performing a cell search procedure or a cell discovery procedure in which a discovery signal is transmitted to a resource element determined in consideration of interference between adjacent cells. The method comprises the steps of: receiving a discovery signal generated by a particular small cell; and searching for the particular small cell on the basis of the discovery signal, wherein the position of the resource element to which the discovery signal is transmitted may be changed according to time.

Abstract: One embodiment of the present description provides a method for monitoring a physical downlink control channel (PDCCH). The method for monitoring a PDCCH can comprise the steps of: performing a frequency division duplex (FDD) half-duplex operation; and determining whether to monitor the PDCCH if discontinuous reception (DRX) is set. Here, when a downlink subframe of a downlink carrier is positioned immediately before an uplink subframe of an uplink carrier, the PDCCH can be monitored in the downlink subframe during an active time.

Abstract: An embodiment of the present specification provides a method for receiving a downlink control channel by a machine type communication (MTC) device. The method comprises: a step of receiving, by the downlink control channel, setting information about the maximum number of physical resource blocks (PRBs) which can be transmitted by a base station; a step of receiving, by the MTC device, setting information about a set of control channel monitoring PRBs which should monitor the downlink control channel; and a step of monitoring the downlink control channel on the PRBs according to the setting information about the set of control channel monitoring PRBs, wherein if the number of sets of control channel monitoring PRBs exceeds the maximum number of PRBs, the downlink control channel may be monitored only on the sets of PRBs equal to or less than the maximum number of PRBs.
