METHOD AND APPARATUS FOR ACCELERATED SUPER 3G CELL SEARCH

摘要

The method and system of a first aspect of the present invention is adapted to perform cell search on all possible bandwidths. In order to reduce the search time, the 5 order in which the allowable BW is used in the search is based on information from history lists. These history lists include the BWs and frequency bands used. A second aspect of the present invention is a method and an OFDM cellular telecommunications system adapted to perform cell search and synchronization wherein the system has a certain number of bandwidth possibilities. The method comprises the steps of 10 identifying at least one critical system parameter that reduces the set of possible synchronization signals; and performing cell search and synchronization over the limited number of different synchronization signals.
