The present disclosure enables a multicast and/or unicast transmitting UE to configure a multicast device-to-device communication and/or the unicast device-to-device communication such that UE may distinguish between the unicast and multicast device-to-device communications. The apparatus receives a unicast device-to-device communication including a destination identifier. The apparatus also receives a multicast device-to-device communication including the destination identifier. The apparatus differentiates the unicast device-to-device communication from the multicast device-to-device communication based on information provided in a header of the unicast device-to-device communication.
