Abstract
A method and an apparatus for augmenting timing synchronization in a base station using backhaul network frequency synchronization are provided. When in a first mode an external time epoch reference synchronized with system time is used to synchronize the base station to system time. When in a second mode a network frequency reference recovered from a backhaul network link is used to maintain the timing synchronization.
