Abstract

The present disclosure describes a method and an apparatus for pruning false peaks during slot synchronization at a user equipment (UE). For example, a method is provided to identify a plurality of first peaks associated with a primary-synchronization channel (P-SCH) received at the UE and a plurality of second peaks from the plurality of first peaks. Further, one or more pruning locations along with associated energy thresholds for each of the plurality of the second peaks may be determined and whether a peak of the plurality of the first peaks is a false peak is identified based on whether the peak is located at one of the one or more pruning locations of the peak and an associated energy value of the peak does not satisfy the associated energy threshold of the pruning location. Furthermore, the peak identified as the false peak is discarded.
