Base station synchronization
Abstract
A method, implemented in a user equipment (UE), of maintaining base station synchronization, comprises receiving a measurement message from a radio network controller (RNC) directing the UE to measure a time difference of arrival (TDOA) between signals transmitted from a first and second base station. The UE receives a transmission from the first and second base stations and measures the TDOA of the transmission from the first and second base station. The UE transmits the measurement of the TDOA of the transmission from the first base station to the first base station, and the measurement of the TDOA of the transmission from the second base station to the second base station.
