Abstract: An apparatus and method for generating reference timings. Each of at least two Node Bs transmits a first channel signal for providing a reference timing and a second channel signal different from the first channel signal and a UE has a plurality of fingers for demodulating the first channel signals. A first timing generator receives an SFN of a reference Node B having a communication link established with the UE, selects a first channel FB timing from a reference finger, and generates an SFN reference timing based on the SFN and the selected first channel FB timing. A second timing generator generates a second channel FB timing to demodulate the second channel signal of the reference Node B from the selected first channel FB timing through offset control. A third timing generator generates an uplink channel FB timing having a predetermined offset from the second channel FB timing.

Abstract: A method of increasing the waiting time of a mobile terminal by reducing power consumption for a cell search in a discontinuous reception mode. In an embodiment of the invention, the strengths of signals from neighbor cells are measured and compared with a first threshold. Then a cell search is performed on only neighbor cells having signal strengths higher than the first threshold. In a second embodiment of the invention, a cell search is not performed if the signal strength of an active set is higher than a second threshold in a discontinuous reception mode. In a third embodiment of the invention, an offline cell search is performed in a discontinuous reception mode in the last step of three conventional cell search steps.

Abstract: A cell search apparatus and method in a mobile communication system. After a UE acquires slot boundary timing and frame boundary timing to a Node B, it acquires its PN code number and PN code timing. After the initial cell search, the UE performs multi-path search by searching a first area with respect to the PN code timing. During reacquisition in a sleep state, the UE searches a second area wider than the first area with respect to a PN code timing acquired before the sleep state. The UE performs neighbor cell search by selectively using the initial cell search and the multi-path search according to whether the Node B provides information or what information it provides.

Abstract: A cell search apparatus and method in a W-CDMA mobile communication system. The cell search apparatus and method performs a first cell search step, a second cell search step, and a third cell search step using a slot count value and a lower count value, counted by an index counter after being initialized upon power up of a UE (User Equipment), thereby determining a scrambling code for a Node B. Further, the cell search apparatus and method manages neighboring Node Bs by performing a multipath search.
