A base station generates and transmits a multi-symbol beacon/timing synchronization signal. The multi-symbol beacon/timing synchronization signal includes: (i) an initial symbol including a body portion and a cyclic prefix, the cyclic prefix preceding the body portion and being generated from an end portion of the body portion and (ii) an extension symbol, which immediately follows the initial symbol. The extension symbol includes a first copy of the body portion beginning at the start of the extension symbol. The first copy of the body portion is immediately followed by a truncated portion, which is a copy of an initial portion of the body portion. The multi-symbol beacon/timing synchronization signal includes a single high power beacon tone, a plurality of low power tones comprising the synchronization signal, and a plurality of intentional Null tones. Each tone designation remains the same for both the initial symbol and the extension symbol.
