Abstract: Provided in one disclosure of the present specification is a method for transmitting a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) for downlink data, when more than five cells are used according to carrier aggregation (CA) by a user equipment (UE). The method comprises the steps of: receiving, from a base station, a list of sets of which HARQ-ACK/NACK transmission is limited, through an upper layer signal; receiving, from the base station, information indicating a set of which HARQ-ACK/NACK transmission is limited at the present turn, from among the list of sets; receiving, from the base station, a plurality of items of downlink data through a plurality of cells; determining the set of which transmission is limited based on the information, from among the list of sets that has been received through the upper layer signal; and generating and transmitting uplink control information (UCI) including HARQ-ACK/NACK for the downlink data but excluding the HARQ-ACK/NACK according to the set which has been determined.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.

Abstract: One downlink control information DCI may be divided into first DCI and second DCI to be transmitted/received. The first DCI may be transmitted/received within a control region of a first TTI of a first time length. The first DCI may include information about the second DCI in a second TTI of a second time length shorter than the first time length. The first DCI may be transmitted/received using first decoding candidates for transmission of the first DCI among decoding candidates in the search space in the control region of the first TTI. The decoding candidates other than the first decoding candidate among the decoding candidates in the search space may be used for transmission/reception of legacy DCI.
