Patent ID: 8054861

Claim:
A process of determining a scrambling code of a base station in a WCDMA mobile device comprising: A. receiving in the mobile device primary, secondary, and tertiary synchronization code signals in parallel on respective first, second, and third synchronization signal channels, the primary, secondary, and tertiary synchronization code signals all occurring at the same regular intervals, the secondary and tertiary synchronization code signals being different from one another in an interval representing a frame having a selected number of slots, and the secondary and tertiary synchronization code signals being different in each slot of the frame; B. identifying a base station primary synchronization code in the received primary synchronization code signals to synchronize with a slot of the frame in the received signals; C. detecting one tertiary synchronization code in the received tertiary synchronization code signals to synchronize with a selected slot of the frame in the received signals; D. using the one tertiary synchronization code to indicate a certain secondary synchronization code group in the secondary synchronization code signals; and E. detecting one secondary synchronization code of the certain secondary synchronization code group in the secondary synchronization code signals to identify a base station scrambling code.
