Abstract: Provided are a discovery method and apparatus. A communication method for a user equipment (UE) may include: receiving first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB); receiving a first message from a second UE via the first resource region; checking whether the contents of the first message match the UE; and sending, when the contents of the first message match the UE, a second message associated with the first message to the second UE via the second resource region. A user equipment (UE) may include: a communication unit configured to receive first resource information indicating a first resource region and second resource information indicating a second resource region from an evolved Node B (eNB), and receive a first message from a second UE via the first resource region; and a control unit configured to check whether the contents of the first message match the UE.
