METHOD FOR ESTIMATING SYNCHRONIZATION

摘要

A method for estimating synchronization of a terminal in a mobile wireless backhaul network comprises the steps of: obtaining distance information between base stations; obtaining a distance between source base stations corresponding to each antenna from a synchronization signal that transceives with a source base station to which a plurality of antennas that come into contact with different source base stations correspond; estimating a distance between an antenna where a handover preparation event occurs and a target base station based on the distance information between the base stations and the distance between the source base stations corresponding to each antenna if the handover preparation event for any one of antennas among the plurality of antennas occurs; and estimating uplink synchronization based on a distance between an antenna where the handover preparation event occurs and a target base station. The present invention is designed to provide a method for estimating synchronization capable of obtaining uplink synchronization without a random access procedure by a terminal in a mobile wireless backhaul network.
