Abstract
The specification and drawings present a method, apparatus and software related product (e.g., a computer readable memory) for improving device discovery and D2D operation, e.g., in LTE wireless systems, by using control signaling provided by a wireless network (e.g., by an eNB). The discovery channel/channels which conveys discovery signal/signals are configured by a network (e.g., by the eNB) and are mapped to control channel/channels (e.g., one-to-one). After sending/receiving the discovery signal/signals, the D2D devices are monitoring control channel/channels to get current information for establishing the D2D communication among these D2D devices, the current information may include a resource allocation for the D2D communication and a device list of candidates for establishing the D2D communication.
