DISTRIBUTED ALGORITHM FOR CONSTRUCTING AND MAINTAINING A HIERARCHICAL STRUCTURE FOR DEVICE-TO-DEVICE SYNCHRONIZATION

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines timing information associated with a synchronization signal to be transmitted. The timing information includes a hop count and a reliability indicator associated with the synchronization signal. The reliability indicator is independent of the hop count and indicates one of reliable or unreliable. The UE broadcasts the timing information with the synchronization signal. The hop count may be a number of hops the synchronization signal is from a base station synchronization signal received from a base station.
