Abstract

A method and apparatus of transmitting and receiving a synchronization signal in a distributed antenna system (DAS) is disclosed. A method of receiving a synchronization signal in a mobile station of a distributed antenna system (DAS) comprises receiving a primary preamble from a base station through one of a plurality of distributed antennas, which is previously defined; and acquiring first synchronization using the primary preamble.
