Abstract: According to one discourse of the present specification, a method for receiving information by a machine type communication (MTC) device is provided. The method of receiving the information may comprise the steps of: monitoring cell-specific control information within a common search space; and monitoring MTC device-specific control information within a UE-specific search space. Here, a resource region in which the common search space (CSS) is located and a resource region in which the UE-specific search space (USS) is located may be configured not to overlap each other.

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.

Abstract: This specification provides a method for transmitting a random access preamble by a user equipment (UE) in a wireless communication system supporting a narrow band-Internet of things (NB-IoT). Specifically, the UE receives a downlink control channel (Physical Downlink Control Channel (PDCCH)) including downlink control information (DCI) from an eNB and the DCI includes an indicator indicating whether a preamble format of a random access preamble allocated to the UE is format 0/1 or format 2. Then, the UE transmits the random access preamble to the eNB in a subcarrier allocated to the UE according to the preamble format and receives a random access response from the eNB in response to the random access preamble.
