Abstract: Disclosed is a method for transmitting, by a user equipment (UE), signals via a device-to-device (D2D) link in a wireless communication system. Specifically, the method comprises the steps of: transmitting a control signal for the D2D link including a timing adjustment value for the D2D link based on a reference timing to a target UE without applying the timing adjustment value; and transmitting a data signal for the D2D link to the target UE with applying the timing adjustment value. Here, the timing adjustment value for the D2D link is same as a timing adjustment value for an uplink to a base station (BS).

Abstract: A user equipment (UE) detects control channels on multiple component carriers in a downlink subframe of a radio frame. An acknowledgement/negative-acknowledgement (ACK/NACK) signal for the detected control channels or data channels corresponding to the detected control channels is transmitted in an uplink (UL) resource region. The UE determines whether UL transmission (Tx) power control fields received at a respective one of the detected control channels are used as values indicating a resource region for transmission of the ACK/NACK signal based on whether a respective one of the detected control channels carries triggering information for activating use of a UL Tx power control field of the respective control channel for aperiodic sounding reference signal (SRS) power control. The UE transmits the ACK/NACK signal in a UL resource region based on a result of the determining, or in a UL resource region linked to the respective one of the detected control channels.
