    摘要： A method and apparatus for performing a power efficient cell search in a multi-cell wireless communication system are disclosed. A wireless transmit/receive unit (WTRU) having a memory that stores a cell identification list of prioritized previously top-ranked cell identities (IDs) is used to perform the cell search. A primary synchronization code (PSC) correlation peak location on a received signal is selected. A common pilot channel (CPICH) correlation value is determined by non-coherent integration of a local signal created based on a first cell ID on the cell identification list to the received signal. If the CPICH correlation value is greater than a noise threshold, thus indicating that the first cell ID is a newly found cell ID, or if a last cell ID in the cell identification list is reached, an additional determination is made as to whether there is more than one cell ID on the list having the same timing.
