摘要： Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available. Signals may include rank information to indicate relay sequence information, and user devices may be configured to respond to signals based on the rank information - such as favoring a signal whose rank indicates that the signal represents a lower relay order number.

摘要： Systems and techniques for managing collisions in discovery of device to device communication capable devices. Depending on whether collision probability is high or low, collision avoidance, or collision detection, may be performed. In collision avoidance, a user device broadcasting a discovery signal includes a cell identifier with the signal. In collision detection, a user device is allocated with an identifying sequence unique to a serving cell. A discovering user device's base station sends a report including a sequence associated with a discovered device to a core network element, which has information relating to sequences and cells of each user device. The network element examines information for neighboring cells of the discovering user device's serving cell and determines if the same identifying sequence associated with the discovered user device is associated with one or more user devices served by neighbor cells to the serving cell of the discovering user device.

A method comprises sending, from a first base station, a first configuration message to at least one of two user equipments which are performing ProSe communication over a first locally routed path via the first base station such that the two user equipments perform the ProSe communication over a second locally routed path via a second base station. The method also comprises sending, from the first base station, a second configuration message to the second base station such that the second base station is configured to support the two user equipments to perform the ProSe communication over the second locally routed path via the second base station.

摘要： Systems, methods, apparatuses, and computer program products for D2D synchronization in, for example, partial coverage scenarios are provided. One method includes sending, by a network node, information to at least one user equipment in a network. The information may be used by the at least one user equipment to determine whether the at least one user equipment is a full-coverage idle mode user equipment or a downlink-only idle mode user equipment. When, for instance at least one of a pair of device-to-device (D2D) user equipment is outside of the network coverage area, the method includes indicating via a cellular broadcasting message to the downlink-only idle mode and the full-coverage idle mode user equipment to send at least one synchronization signal. The method may then include configuring a RRC_Connected mode user equipment at cell-edge to monitor whether there are user equipment sending synchronization signals.
