Реферат: Techniques and apparatus for achieving multi-cell synchronization for dual connectivity and carrier aggregation are described. In one technique, a timing difference between a first base station (BS) and a second BS is determined, where the first BS is in an asynchronous timing configuration with respect to the second BS. A measurement configuration for measuring signal (s) from the second BS is determined, based on the timing difference. The measurement configuration is signaled to a user equipment (UE) served by the first BS. The UE performs a measurement procedure for the signal (s) in accordance with the measurement configuration. In another technique, the second BS receives a synchronization request, which includes a first time stamp, from the first BS via a network interface between the first BS and the second BS. The second BS sends a synchronization response, which includes a second time stamp, to the first BS.
