Abstract:
1. A controller, the controller being embodied in an apparatus that comprises a wireless network access node that is coupled to at least one other wireless network access node, the controller being configured to implement modules configured to derive two different timings from a timing source, wherein a first derived timing is a physical timing used for timing at least transmissions of frames from the wireless network access node, and wherein a second derived timing is a virtual timing representing a currently preferred physical frame timing, where the virtual timing representing the currently preferred physical frame may or may not be equal to a current physical timing; configured to receive an indication of a virtual timing from the at least one other wireless network access node; configured to compare the at least one received virtual timing indication with the derived virtual timing of the wireless network access node, and update the derived virtual timing; and configured to determine achieving synchronization of the derived virtual timing with the at least one received virtual timing, and to adjust the physical timing accordingly.
