Abstract: A disclosure of the present specification provides a method for receiving, from a serving cell, a downlink control channel subject to interference from a neighboring cell. The method comprises the steps of: receiving information on discontinuous reception (DRX), wherein the information on discontinuous reception includes information on a period comprising an interval in which the downlink control channel is monitored and an interval in which the downlink control channel is not monitored; and monitoring the downlink control channel received from the serving cell in the interval in which the downlink control channel is monitored. Here, the downlink control channel may be monitored in a state where the interference from the neighboring cell has not been alleviated.

Abstract: One embodiment of the present specification provides a method for allocating resources to user equipment (UE) supporting 256 quadrature amplitude modulation (QAM) demodulation. The resource allocation method can comprise the steps of: receiving a channel quality information (CQI) report from the UE; determining, by the UE, whether a backoff of transmission power has been applied to a downlink subframe from which CQI is measured; determining whether the backoff of the transmission power is to be applied to the downlink subframe which is supposed to allocate the resources; and determining a modulation coding scheme (MCS) level on the basis of the CQI and the results of the determination.

Abstract: One disclosure of the present specification provides a method for identifying a secondary cell on the basis of discovery signals. The method may comprise the step of receiving information on a discovery signal measurement timing configuration (DMTC) and a measurement cycle from a serving cell. The DMTC may include a DMTC periodicity. The measurement cycle may indicate the measurement cycle of an inactivated secondary cell (Scell) by subframe unit. The method may comprise the step of identifying the secondary cell. If DRX is used, the secondary cell is considered an intra-frequency cell, and the secondary cell is a small cell and identified based on discovery signals, the identification of the small cell can be performed in two hours.
