Abstract: The present specification provides a method for receiving data through interference cancellation. The method can comprise the steps of: receiving a transmission signal transmitted by a DMRS-based transmission method; detecting, from the transmission signal, a DMRS-based transmission parameter for an interference cell having caused interference in the transmission signal; estimating an interference channel for the interference cell on the basis of the detected DMRS-based transmission parameter; generating an interference signal for the interference cell on the basis of the estimated interference channel; and cancelling the generated interference signal from the transmission signal so as to restore data transmitted by a serving cell.

Abstract: A method for downlink beamforming in a wireless access system and a device therefor are disclosed. Specifically, the method comprises the following steps: transmitting, by an eNB, a reference signal to a UE through only a first antenna set from among whole antennas; receiving, by the eNB, channel state information (CSI) for the first antenna set from the UE; and transmitting, by the eNB, beamforming a downlink channel by using a precoding matrix for the whole antennas, wherein CSI for a second antenna set by which the reference signal has not been transmitted from among the whole antennas is calculated using the CSI for the first antenna set.

Abstract: Provided are a discontinuous reception (DRX) operation method of a terminal in a wireless communication system and an apparatus applying the method. The method comprises the steps of: receiving, from a base station, first configuration information which indicates a monitoring occasion for detecting first DCI comprising information that indicates whether the terminal has woken up; receiving, from the base station, second configuration information which indicates an operation to be applied to the terminal when the first DCI is not detected; monitoring a first PDCCH in order to detect the first DCI in the monitoring occasion; and when the first DCI fails to be detected in the monitoring occasion, monitoring a second PDCCH for detecting not the first DCI but second DCI in a next DRX-on duration on the basis of the second configuration information.

Abstract: A transmission device may perform listen-before-talk (LBT) with regard to an unlicensed band. The transmission device may determine M LBT sub-bands which are in an idle state, on the basis of the performing of the LBT for the unlicensed band. The transmission device may perform N repetitive transmissions of a transport block (TB) over the M LBT sub-bands. The N repetitive transmissions of the TB may include performing M repetitive transmissions over the M LBT sub-bands, respectively.
