Patent ID: 8599828

Claim:
A method for identifying a cell and a sub-frame by detecting a part of a secondary synchronization signal of a dedicated synchronization channel, said part of a secondary synchronization signal including a time-domain sequence of N OFDM symbols, N being a positive integer, wherein the method comprises: for each OFDM symbol among said sequence of N OFDM symbols: a step of obtaining a set of metrics for each OFDM symbol, each metric of said set of metrics being associated with a predetermined combination of a cell identifier and a sub-frame alignment; for each metric of said set of metrics: a step of counting a number of times the metric exceeds a first predetermined threshold, delivering a summed value M indicating the number, and a step of applying a M among N criterion to said summed value M, delivering a M/N ratio value; and a step of analyzing said M/N ratio values, in order to identify the cell and the sub-frame, corresponding to the cell identifier and the subframe alignment, associated to a particular ratio value among said M/N ratio values.
