Claim:
1. A method of wireless communication of a user equipment (UE), the method comprising: receiving a synchronization signal and timing information from each UE of a set of UEs upon the UE turning on; determining a set of reliable timing information of the timing information received from the set of UEs, wherein the reliable timing information includes a reliability indicator indicating that the received synchronization signal is reliable; determining a lowest hop count of one or more hop counts in the set of reliable timing information when the set of reliable timing information is not an empty set; determining a second timing information associated with a second synchronization signal to be transmitted, the second timing information including a second hop count and a second reliability indicator associated with the second synchronization signal, the second reliability indicator being independent of the second hop count and indicating one of reliable or unreliable; and broadcasting the second timing information with the second synchronization signal, wherein the second reliability indicator included in the second timing information is set by the UE to the one of reliable or unreliable, wherein when the set of reliable timing information is not an empty set:
