Abstract: Disclosed is a method for a terminal to transmit an uplink data signal in a narrowband wireless communication system. Specifically, the method comprises the steps of: receiving, from a base station, a downlink control signal including resource allocation information for resource blocks continuously allocated for the uplink data signal within allocable resource blocks; and transmitting the uplink data signal to the base station using the downlink control signal, wherein the continuously allocated resource blocks are updated to include a center resource block, when the allocable resource blocks include the center resource block of a system bandwidth.

Abstract: A method for receiving a downlink control channel by a user equipment (UE) in a wireless communication system is disclosed. The method includes receiving downlink control information (DCI) indicating an aggregation level being a reference for allocating a downlink data channel to a control region, determining a last control channel element (CCE) index to which the downlink control channel is allocated, based on the received DCI, configuring a downlink control channel transmission region in consideration of the last CCE index and a resource region for one or more downlink control channel candidates corresponding to the aggregation level, and configuring a remaining control region except for the downlink control channel transmission region as a downlink data channel transmission region, and receiving the downlink control channel and the downlink data channel in the control region, based on the configured downlink control channel transmission region and the configured downlink data channel transmission region.

Abstract: The disclosure of the present invention proposes a method for monitoring control information. The method may be performed by a user equipment (UE) configured with an aggregation of a first cell and a second cell. The method may comprise: monitoring, by the UE, control information in a control region of at least one of the first and second cells. The first cell uses a first transmission time interval (TTI) and the second cell uses a second TTI.

Abstract: A method is disclosed for detecting downlink control information. In particular, the method comprises: a step of detecting first downlink control information transmitted from a specific cell; a step of detecting second downlink control information included in a shortened downlink control channel, based on resource information about the shortened downlink control channel included in the first downlink control information, if the first downlink control information is detected; and a step of changing any one of a shortened downlink data channel, a shortened uplink data channel, and transmission/reception timings of ACK/NACK signals, which are set in advance based on the performance of the terminal, if the first downlink control information is not detected.

Abstract: Provided are a method and a device for reporting a power headroom in a wireless communication system. The device receives initial downlink control information (DCI) for physical uplink shard channel (PUSCH) transmission in a first subframe and receives triggering DCI in a second subframe. The device calculates a power headroom on the assumption that the PUSCH transmission is not performed.
