    Abstract: The present invention relates to a method and an apparatus for transmitting control information for device-to-device (D2D) communication. A method for communicating between terminals of a transmission terminal according to an embodiment of the present invention comprises the steps of: determining whether transmission data corresponds to final transmission data; generating a first channel sensing signal including information indicating that the transmission data corresponds to final transmission when the transmission data is final transmission data; and transmitting the transmission data and the first channel sensing signal. According to an embodiment of the present invention, a channel sensing signal, which is necessarily required for a D2D operation of a distributed resource allocation scheme, is used to transmit the control information so that control information can be exchanged between terminals without introducing an additional control channel and signal.

    Abstract: Provided are a method and apparatus for transmitting control information in device-to-device (D2D) communication. A D2D communication method for a transmitting user equipment (Tx UE) may include: sending a channel sensing signal containing priority information of the Tx UE and data; checking whether a resource transfer request message containing priority information is received from a receiving user equipment (Rx UE); checking, when a resource transfer request message is received, whether the priority of the Tx UE is lower than the priority of the Rx UE; and terminating, when the priority of the Tx UE is lower than the priority of the Rx UE, transmission of the data. As the channel sensing signal required for D2D communication based on distributed resource allocation is used to convey priority information, it is possible to minimize overhead due to introduction of additional control channels and signals for acquiring radio resources.

    Abstract: A method and system are provided for a terminal to measure channel quality and transmit channel state information to a base station in a wireless mobile communication system operating in a multi-carrier-based multiple access scheme such as Orthogonal Frequency Division Multiple Access (OFDMA). The feedback information transmission method of a terminal in a mobile communication system includes receiving configuration information corresponding to at least two reference signals from a base station, receiving, at the terminal, feedback configuration information for measuring the at least two reference signals and generating feedback information based on a measurement result, receiving, at the terminal, the at least two reference signals, and transmitting, by the terminal, the feedback information at timings indicated in the feedback configuration information.
