Abstract
A method and apparatus are provided for identifying a cell and a sub-frame by detecting a part of a secondary synchronization signal including a sequence of N OFDM symbols. For each OFDM symbol, the method obtains a set of metrics, each metric being associated with a predetermined combination of a cell identifier and a sub-frame alignment (CID/SF). For each metric, the method counts the number of times a metric exceeds a first predetermined threshold, delivering a summed value, and applies an M of N criterion to the summed value, delivering a ratio value. The ratios values are analyzed in order to identify the cell and the sub-frame, corresponding to a cell identifier and a sub-frame alignment, associated to a particular ratio value among the ratios values, which exceeds a second predetermined threshold.
