A method and an apparatus for wireless communication with dual connectivity are described. The apparatus supports dual connectivity with a first cell and a second cell and the apparatus comprises a radio frequency (RF) and a processor operatively coupled to the RF unit. The second cell is an overlaid virtual cell which is formed by collaborating the first cell and cell ID of the second cell is different from physical cell ID of the first cell when the processor uses primary synchronization signal (PSS), secondary synchronization signal (SSS) or cell-specific common reference signal (CRS) as synchronization signal for the second cell.
