Abstract
A method for setting up a multiple radio access technology (multi-RAT) device-to-device (D2D) communication is disclosed. An application function (AF) in a wireless transmit/receive unit (WTRU) may identify a group of multiple radio access technology (multi-RAT) capable WTRUs to a policy control function (PCF), wherein one or more multi-RAT capable WTRUs of the group of multi-RAT capable WTRUs register as having enhanced device-to-device (ED2D) functionality. The AF may select a multi-RAT capable WTRU from the group of multi-RAT capable WTRUs having ED2D functionality, as a relay for extended D2D operation. The device with ED2D function will act as Relay for ED2D (RED2D). The PCF may then reconfigure the RED2D with group related information. The RED2D may then configure D2D communication among the group of multi-RAT capable WTRUs.
