Abstract
In an embodiment, for a case in which there is an active connection established between a cellular network and a user equipment UE and the UE has simultaneously an active connection within a local network distinct from the cellular network, there is an indication within a resource allocation message communicated between the cellular network and the UE which is used to identify whether a radio resource allocated by the resource allocation message is for the cellular network or for the local network. In various embodiments, the local network is a D2D network and the message is directed to a C-RNTI associated with the D2D network; and/or a value of the indication identifies the allocated radio resource as an allocation for the D2D network or for the cellular network and also whether the allocation is to the UE or to a paired D2D device or to both.
