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.
