Abstract: Apparatuses (including user equipment (UE) and modem chips for UE), systems, and methods for reducing false alarms (FAs) and miss-detections (MDs) in cell search results are described. In one method, the minimum of a value for the accumulated metric for a first short code and a value for the accumulated metric for a second short code is used as a pruning metric for each candidate cell. One or more thresholds are applied to the pruning metric to determine whether the candidate cell will be pruned from the final candidate cell list.

Abstract: Apparatuses (including user equipment (UE) and modem chips for UE), systems, and methods for calculating more accurate Reference Signal Received Power (RSRP) measurements and/or detecting/eliminating ghost cells from a list of (supposed) neighboring cells are described. In one method, the cross-correlations between adjacent Cell-specific Reference Signals (CRSs) are used to calculate the RSRP and to detect any ghost cells in a list of (supposed) neighboring cells. Any detected ghost cell may be deleted from any searches and measurements by the UE, and may also be reported to the network.
