Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.

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: The present invention provides a method for re-establishing a link between terminals in a wireless communication system, and a device therefor. Particularly, the method for a first terminal to re-establish a link with another terminal in a wireless communication system comprises: a step of determining a radio link failure with respect to a radio link with a second terminal; a step of transmitting a first message, requesting measurement for re-establishing the radio link with the second terminal, to a base station on the basis of the determined radio link failure; a step of receiving a second message, including information on the configuration of the measurement, from the base station in response to the transmitted first message; and a step of transmitting, to the base station, a third message including a report on the radio link with the second terminal which has been re-established by performing the measurement based on the information on the configuration.

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: A disclosure of the present specification provides a method for performing link adaptation by a serving cell which performs interference randomization for inter-cell interference control. The method may comprise the steps of: acquiring interference information on at least one coordination cell to which interference coordination is to be applied among neighbor cells; and performing link adaptation on the basis of the interference information, wherein the interference information includes information on a modulation level, which indicates a modulation scheme for the coordination cell.
