Abstract
A method includes configuring one or multiple pools of Device-to-Device (D2D) communication resources by an eNodeB (eNB). The method also includes signaling of the configured pool(s) of D2D communication resources by the eNB to a first User Equipment (UE) and a plurality of UEs using a common broadcast channel; and sending a request for one or multiple D2D communication resources to an eNB by the first UE configured to transmit D2D messages. The method also includes determining one or multiple resources for D2D communication by an eNB for the first UE. The method also includes communicating D2D resource allocation information to the first UE. The method also includes communicating D2D resource allocation information by the first UE to multiple UEs; and transmitting D2D data by the first UE to multiple UEs. Methods for configuring and signaling D2D communication resources by relay or out-of-coverage UEs are also provided.
