Abstract
A method and apparatus for identifying a base station is provided herein. Particularly, a received reference sequence comprising a GCL-based sequence is analyzed to determine an index of the GCL-based sequence. The index of the GCL-based sequence is then mapped to a base station identity.
Claims15
A method for identifying a base station, the method comprising the steps of:
- receiving a reference sequence comprising a GCL-based sequence;
- determining an index of the GCL-based sequence;
- and
- mapping the index of the GCL-based sequence to a base station identity.

A method for a communication unit to identify an index of a received reference sequence, the method comprising the steps of:
- receiving a reference sequence;
- computing a differential-based value between each of a plurality of pairs of elements of the received reference sequence;
- analyzing/processing the differential-based values to identify a prominent frequency component;
- and
- mapping the identified prominent frequency component to a corresponding transmitted sequence index based on a predetermined mapping scheme.
