Abstract
Official abstract text for this publication.
A mobile device receives a radio frequency (RF) signal comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device performs multiple frequency hypothesis (MFH) testing via multiple MFH branches. A SSS decoding and a PSS correlation process are performed, respectively, per MFH branch. The SSS decoding may be performed according to corresponding PSS detection. Cell-specific information such as cell ID information and/or Cyclic Prefix (CP) length is acquired per MFH branch based on corresponding PSS detection and SSS decoding. Subsequently, the mobile device selects a particular MFH branch with a maximum PSS correlation peak over the entire MFH branches. The cell-specific information from the selected MFH branch is utilized for communications within a corresponding cell if the information is detected consistently. The mobile device compares cell ID information and/or CP length information over the remaining MFH branches for consistency check.
First claim
Opening claim text (preview).
What is claimed is: 1. A method, comprising: receiving cell-specific information from a plurality of multiple frequency hypothesis (MFH) branches, wherein the cell-specific information includes a plurality of cell ID information and a plurality of cyclic prefix (CP) length information for the plurality of MFH branches; selecting a first branch in the plurality of MFH branches based on a primary synchronization sequence (PSS) correlation peak magnitude of the first branch; and…
