Abstract: The present invention relates to a method for transmitting an hybrid automatic repeat request acknowledgement/negative-acknowledgement (HARQ-ACK/NACK) on the basis of a wide area network (WAN) of a device-to-device (D2D) terminal in a time division duplex (TDD)-based wireless communication system. Specifically, the method comprises the steps of: receiving a downlink HARQ reference configuration for WAN communication; and transmitting a HARQ-ACK/NACK from a downlink HARQ reference configuration-based first uplink subframe, wherein the first uplink subframe is an uplink subframe configured so as to communicate only via WAN.

Abstract: The present specification discloses a transmission/reception method for a machine type communication (MTC) apparatus. The transmission/reception method for the MTC apparatus may comprise the steps of: receiving, by the MTC apparatus, setting information about a multicast-broadcast single-frequency network (MBSFN) subframe from a base station; receiving, by the MTC apparatus, downlink data for the MTC apparatus, on a data region of the MBSFN subframe; and receiving, by the MTC apparatus, a cell-specific reference signal (CRS) only on a portion of the resource blocks (RBs) in the whole system bandwidth of the data region in the MBSFN subframe. Here, the CRS received only on the portion of RBs may be transmitted while electric power is increased by means of the base station.

Abstract: A method for a wireless device to which a plurality of serving cells are assigned transmitting uplink control information (UCI) in a wireless communication system is provided. The wireless device transmits uplink data in a subframe to a physical uplink shared channel (PUSCH), and transmits UCI including a hybrid automatic repeat request (HARQ) ACK/NACK and periodic channel state information (CSI) in the subframe to a physical uplink shared channel (PUCCH). The PUCCH and the PUSCH have the same demodulation reference signal (DMRS) location within the subframe.

Abstract: A method is provided for determining transmit power of an uplink control channel of a user equipment to which two cells having different uplink (UL)-downlink (DL) configurations are assigned. A larger value between N1, the number of downlink subframes corresponding to a subframe n of a first cell having a first UL-DL configuration, and N2, the number of downlink subframes corresponding to a subframe n of a second cell having a second UL-DL configuration is chosen. A parameter value is determined based on the chosen value.

Abstract: A disclosure of the present specification provides a method for receiving a control channel in a search space. The method may comprise the steps of: determining an order of multiple search spaces in a blind decoding; and performing the blind decoding in the multiple search spaces according to the determined order. In this regard, the order of the multiple search spaces may be determined on the basis of delay sensitivity.
