Abstract: Provided are a method and an apparatus for transmitting retransmission data using an HARQ in a wireless communication system. Specifically, it is determined whether there is a radio resource for transmitting retransmission data. When the radio resource exists, a DCI format including a retransmission indicator field is configured. The retransmission indicator field indicates whether the retransmission data is general retransmission data or opportune retransmission data. The opportune retransmission data is retransmitted before an ACK/NACK signal for initial transmission data is received. The retransmission data is transmitted through the radio resource according to scheduling of a configured DCI format.

Abstract: A method and a device for controlling power in a TDD-based wireless communication system are provided. Particularly, a first resource block group for a first terminal and a second resource block group for a second terminal are configured. The first resource block group is configured in a partial frequency band of the entire frequency band. The maximum transmission power of the first terminal is controlled for the first resource block group according to the ratio between the number of subcarriers in the first resource block group and the number of subcarriers in the second resource block group. An uplink signal of the first terminal and an uplink signal of the second terminal are received through the first resource block group.

Abstract: Provided are a method and an apparatus for performing communication in a wireless communication system. Specifically, a control channel element is configured by using a resource element group in the same symbol of a resource block. The resource element group includes a plurality of resource elements in the same symbol. The resource block is transmitted in units of sTTIs which is set to be shorter than TTI. A control channel corresponding to the control channel element, and a data channel scheduled by the control channel are configured. The control channel and the data channel are transmitted in different frequency bands. Data is transmitted through the data channel.

Abstract: A method for transmitting and receiving data in a wireless communication system and an apparatus for the method are disclosed. More specifically, a method for transmitting downlink data in a wireless communication system comprises transmitting, by an eNB, first downlink data through a physical downlink shared channel (PDSCH) region according to a radio frame structure based on a first transmission time interval (TTI); and transmitting, by the eNB, second downlink data through a short PDSCH (sPDSCH) region according to a radio frame structure based on a second TTI, wherein downlink control information (DCI) related to the second downlink data is transmitted through a physical downlink control channel (PDCCH) or a short PDCCH (sPDCCH).
