Systems, Apparatus and Techniques for Fast Cell Search and Accurate Synchronization in Wireless Communications

A wireless communication mobile station, comprising:

• a mechanism that controls the mobile station to detect a downlink signal received from a base station, wherein the downlink signal comprises a cell identification sequence as a leading symbol of and as at least part of a preamble of every downlink subframe in time, at least one data symbol, at a position subsequent to the cell identification sequence in time, in every downlink subframe of the downlink signal, and, in every other L frames of the downlink signal, at a position subsequent to the cell identification sequence in time, a symbol comprising a plurality of copies of a sequence placed sequentially in time, wherein L is an integer greater than 0 and the sequence is common to at least a portion of base stations with which the mobile station communicates, wherein the cell identification sequence is one of a set of cell identification sequences and is designated to identify a base station and a cell sector of the base station;
• a mechanism that controls the mobile station to perform synchronization in time and frequency based on the sequence;
• and
• a mechanism that controls the mobile station to perform a correlation between the cell identification sequencer and the set of cell identification sequences to identify the cell sector and the base station.
