ABSTRACT:
A user equipment (UE) for establishing a communication link comprising a first module for processing a received communication signal and generating an index value associated with a primary synchronization code within said communication signal; a second module for generating a scrambling code group number, a slot offset, and secondary synchronization code based on output provided by the first module; a third module for retrieving a primary scrambling code based on the scrambling code group number and slot offset; and a controller coupled to said first module, second module, and third module for controlling an a search frequency of the UE for establishing a communication link.
