Abstract
An apparatus and method in a wireless communication system. The apparatus includes circuitry configured to: generate configuration information about a user equipment including retransmission time related information and used for performing device-to-device communication, wherein the re-transmission time related information represents information related to retransmission times of signal transmission with a user equipment performing device-to-device communication; and to transmit the generated configuration information to the user equipment performing device-to-device communication. A signal in device-to-device communication can be ensured to be accurately and completely transmitted between various communication devices participating in the communication, and thus the transmission performance of information is improved.
