Abstract
There is provided a method for acquiring and modifying uplink and downlink synchronization, by which, if there is a possibility of ISI occurring due to incorrect downlink synchronization of a terminal with a base station, the terminal receives a ranging response from the base station, modifies incorrect downlink synchronization, and acquires uplink synchronization in accordance with modified downlink synchronization. The method for acquiring and modifying uplink and downlink synchronization efficiently prevents, in a cooperative communication network, discrepancy in signal transmission synchronization between the base stations, excessive attenuation of a transmitted signal, or a delay caused by a difference in reflection paths.
