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 is a method for transmitting a signal by a terminal via a device to device (D2D) link in a wireless communication system. Specifically, the method comprises: a step for receiving information on a timing advance (TA) value from a base station; a step for transmitting the TA value to a counterpart terminal via a first D2D control channel; and a step for transmitting a D2D data channel based on the first D2D control channel to the counterpart terminal by applying the TA, wherein the TA is not applied to the first D2D control channel. In particular, when the information on the updated TA value is received from the base station, it is desirable to transmit the D2D data channel based on the first D2D control channel to the counterpart terminal by applying the updated TA, but in the case of applying the updated TA, not to apply the information on the TA value included in the first D2D control channel.
