In order to address the needs of narrow band communication, eNB-based processing and/or UE-based processing is provided to achieve robust detection of cell ID and SFN timing location using NB-SSS. A base station constructs a NB-SSS signal using a root index of a Zadoff-Chu (ZC) sequence, a scrambling code, a cyclic shift or phase ramping sequence, and an interleaving sequence, wherein a combination of the ZC root index, the scrambling code index, the cyclic shift or phase ramping sequence index, and the interleaving sequence index signals information for a cell identifier (e.g., PCID) and frame timing. The ZC sequence used may be a long ZC sequence constructed to span a total number of tones allocated to an SSS sequence or may be a concatenation of multiple ZC sequences, wherein the concatenated ZC sequences span a total number of tones allocated to an SSS sequence.
