1. A method performed by a wireless transmit/receive unit (WTRU) for establishing device-to-device (D2D) communication, the method comprising:
registering with a network, the WTRU as having enhanced device-to-device (ED2D) functionality including multi-radio access technology (multi-RAT) support and configurability to serve as a relay ED2D (RED2D) between the network and one or more wireless D2D-enabled devices;
receiving, via the network, authorization of the WTRU to serve as the RED2D between the network and a group of devices, wherein the group of devices comprises at least one D2D-enabled wireless device from a first category of devices using a 3GPP radio access technology and at least one D2D-enabled wireless device from a second category of devices using non-3GPP radio access technology;
receiving, via the network, group related information comprising identities of devices in an authorized group of devices and a related group ID; and
configuring by the WTRU, D2D communication among the authorized group of devices associated with the group ID.
