摘要： 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 scrambling code number and scrambling code timing. After the initial cell search, the UE performs multi-path search by searching a first area with respect to the scrambling code timing. During reacquisition in a sleep state, the UE searches a second area wider than the first area with respect to a scrambling 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.

摘要： 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.

摘要： An apparatus and method of receiving multi-path signals in a direct sequence Code Division Multiple Access (CDMA) mobile communication system is disclosed. Timing control signals from respective fingers are collected, and relations among positions of time delays where the respective fingers intend to perform a demodulation are analyzed. If it is determined that the time delay position for a specified finger approaches the time delay position of the finger allocated with an adjacent multi-path as close as a threshold value, the distance between the time delay positions is compulsorily kept as the threshold value. This can be effected by making the timing control signal of the finger allocated with the adjacent multi-path be equally used in the specified finger.

摘要： 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.
