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 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.

摘要： A method and an apparatus are provided for managing cell-by-cell demodulation timing of an asynchronous user equipment (UE) for demodulating multipath signals, received from a plurality of cells, in a plurality of fingers. Mapping information, indicating fingers mapped on a cell-by-cell basis, and demodulation information and demodulation timing information for the plurality of cells are acquired. The fingers are grouped on a cell-by-cell basis according to the mapping information. Demodulation information for an associated cell is provided to each of the grouped fingers. A signal received from the associated cell is demodulated in the grouped fingers by using the demodulation information for the associated cell. System load and costs can be reduced by managing demodulation timings on a cell-by-cell basis in the UE that simultaneously perform data transmission/reception with the cells in which transmission timings are different from each other in a soft handover situation in an asynchronous mobile telecommunication system.
