Synchronization techniques for wireless nodes in a shared radio frequency spectrum band may include performing a listen before talk (LBT) procedure (e.g., a clear channel assessment (CCA) procedure) at identified resynchronization boundaries and initiating transmissions following successful LBT procedures. In the event that a node loses synchronization between resynchronization boundaries, such as due to an unsuccessful LBT procedure, the node becomes unsynchronized and may initiate an LBT procedure separate from the other nodes of the set of nodes. At a subsequent resynchronization boundary, the unsynchronized node may perform a resynchronization procedure in order to again become synchronized with other nodes of the set of nodes. In cases where the resynchronization procedure is unsuccessful, a parameter associated with the resynchronization procedure may be adapted to increase an interval for performing the resynchronization procedure.
