US Patent 9591679 Initiation of inter-device communication in wireless communication systems

Systems, methods, and apparatuses for initiation of inter-device communication in wireless communication systems are provided. Both a user equipment (UE) and a network entity may initiate a direct inter-device communication link between UEs located in proximity. The UE may simultaneously maintain an active communication link with its serving base station while communicating with other UEs over the inter-device communication link. Long term evolution (LTE) downlink or uplink radio resources may be used for communications over the inter-device communication link.
