Abstract
The invention is related to wireless communication systems, methods, devices, computer program, and computer-readable memory medium, and, more specifically, relate to synchronization techniques. The invention relates to a method, including deriving two different timings from a timing source, wherein a first derived timing is a physical timing used for timing at least transmissions from a wireless network access node, and wherein a second derived timing is a virtual timing representing a currently preferred physical timing; receiving an indication of a virtual timing from at least one other network access node; comparing the at least one received virtual timing indication with the derived virtual timing of the network access node, and update the derived virtual timing; and determining achieving synchronization of the derived virtual timing with the at least one received virtual timing, and to adjust the physical timing accordingly.
