Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a set of non-overlapping periodic intervals for monitoring a synchronization signal, which may be composed of or may include a repeated sequence; and the UE may identify possible timing structure (e.g., subframe, slot, etc.) boundaries using the intervals. The UE may then determine that one of the possible boundaries is a boundary using a second synchronization signal. For instance, the UE may perform a cumulative correlation during each of a series of correlation periods corresponding to the periodic intervals. Each of the cumulative correlations may contain multiple coherent correlations associated with the sequence repetitions. From the cumulative correlations, the UE may identify possible boundaries. The UE may perform a secondary correlation based on a second synchronization signal for each possible boundary in order to determine the system timing.
