Abstract: Methods and systems which provide for synchronization target selection by configuring a network device to reselect a synchronization signal transmission timeslot for synchronization target searching by the network device are described. Synchronization signal timeslot reselection may provide for downgrading a current stratum index to an artificial stratum index that does not accurately indicate a number of hops between the network device and a global synchronization source to allow for selection of available synchronization targets with stratum indices that are higher than or equal to the network device's stratum index without causing a synchronization loop. A synchronization signal pattern cycle structure having synchronization signal timeslots organized into multiple subcycles for accommodating synchronization signal timeslot reselection is utilized according to embodiments.
