摘要： Techniques are disclosed that provide for femto base stations to become synchronized with other base stations in a wireless network. For instance, a macro base station may instruct a mobile station to engage in a synchronization operation that synchronizes one or more timings (e.g., OFDM timings) of a femto base station with one or more corresponding timings of the macro base station. This may involve the mobile station having timing references of the macro base station. Further, this may involve the mobile station performing scanning operations and/or handover ranging operations with the femto base station. The mobile device may determine timing offsets between the femto BS and the macro BS. These offsets may be sent to the macro base station or to the femto base station. Also, the femto base station may adopt timings employed by the mobile station. The macro base station or a femto base station may direct a femto base station to achieve synchronization either directly with timing adjustment offset, or with a list of already synchronized femto base station as synchronization reference.
摘要翻译：公开了提供毫微微基站与无线网络中的其他基站同步的技术。例如，宏基站可以指示移动台进行将毫微微基站的一个或多个定时（例如，OFDM定时）与宏基站的一个或多个对应定时同步的同步操作。这可能涉及具有宏基站的定时参考的移动站。此外，这可能涉及移动台与毫微微基站执行扫描操作和/或切换测距操作。移动设备可以确定毫微微BS与宏BS之间的定时偏移。这些偏移可以被发送到宏基站或毫微微基站。此外，毫微微基站可以采用移动台采用的定时。宏基站或毫微微基站可以指示毫微微基站直接与定时调整偏移或者与作为同步参考的已经同步的毫微微基站的列表实现同步。
