Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

Abstract: Disclosed herein are a method and apparatus for sending and receiving data in a wireless communication system. More specifically, a method for sending and receiving, by UE, data in an unlicensed band in a wireless communication system may include performing blind detection for detecting a predetermined specific signal transmitted by an eNB in a cell of an unlicensed band and determining a period in which the signal is detected through the blind detection to be a reserved resource period (RRP) which is a time period secured for the transmission and reception of data in the cell of the unlicensed band.

Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a signal by a terminal in a wireless communication system supporting reconfiguration of wireless resources. Specifically, the method comprises a step of monitoring wireless resource reconfiguration control information on a number of sub-frames within a set monitoring cycle in order to reconfigure wireless resources, wherein a first uplink-downlink setting in accordance with wireless resource reconfiguration control information is valid only if equally detected on a number of sub-frames, and wherein a number of sub-frames are sub-frames set to monitor wireless resource reconfiguration control information of a terminal.

Abstract: A method of receiving a synchronization signal for device-to-device (D2D) communication by a user equipment (UE) in a wireless communication system is provided. A synchronization signal is received from a base station (BS) to acquire synchronization. Information on capability of the UE related with a synchronization mode is transmitted to the BS. Information on the synchronization mode indicating a first synchronization mode or a second synchronization mode is received from the BS. A reference synchronization of transmitting a D2D signal is determined based on the synchronization mode. When the information on the synchronization mode indicates the second synchronization mode, a synchronization signal is received from a device except for the BS to acquire synchronization for D2D communication.

Abstract: A method for transmitting downlink data in a multicast scheme by a base station in a wireless communication system is disclosed. The method includes receiving a first request signal requesting first data from a first user equipment (UE), receiving a second request signal requesting second data from a second UE, generating a transmission message by applying an exclusive OR (XOR) operation to the first data and the second data, and transmitting the transmission message to the first UE and the second UE in the multicast scheme.

Abstract: The disclosure of the present specification provides a method for receiving a downlink control channel in a machine type communication (MTC) device configured to operate in only a partial band of the system band of a cell. The method may comprise the steps of: considering the number of physical resource block (PRB) pairs, to which a downlink control channel can be mapped, to be one of 2, 4, and 8; when the considered number of PRB pairs is greater than the number of PRB pairs to which the downlink control channel is actually mapped, determining that the downlink control channel is not included in PRB pairs except the number of PRB pairs to which the downlink control channel is actually mapped; and receiving the downlink control channel in only as many PRB pairs as the number of PRB pairs to which the downlink control channel is actually mapped, on the basis of the determination.
