Abstract
A mobile station can be connected to more than one base station in a procedure known as macro-diversity. In order to synchronize the signals for a specific cellular call connection, the time difference between the connected base station's signal and a macro-diversity candidate base station's signal is measured by a mobile station. This measurement is then transmitted to the network. The measurements can be used to achieve synchronization via frame staggering.
