A method and apparatus for synchronization in an orthogonal frequency division multiplexing (OFDM) network is disclosed. A wireless transmit/receive unit (WTRU) is configured to receive a primary synchronization signal and a secondary synchronization signal from a cell. The primary synchronization signal and the secondary synchronization signal are spaced by a known number of OFDM symbols. The primary synchronization signal and the secondary synchronization signal are received in a same number of subcarriers in their respective OFDM symbol. A location of at least the secondary synchronization signal in the system bandwidth is variable.
