Motivation
• Since the speed of an AMS in a femtocell is
not so fast, the largest frequency offset
caused by the Doppler effect (related to
mobile station maximum velocity) has been
further relaxed to 250 ppb.
• We suggest that the Femto ABS can use
wireless link for synchronization (e.g, with a
Macro ABS or a synchronized Femto ABS).
Proposed Text
[Add the following text in section 15.4.6 “Network
synchronization for femto ABS”]
15.4.6 Network Synchronization for femto ABS
The Femto ABS may also achieve network
synchronization from GPS or backhaul network (e.g.
IEEE 1588). A Femto ABS should be synchronized
with the overlay Macro ABS network.
