Abstract:
1. A method for managing cell-by-cell demodulation timings of an asynchronous user equipment (UE) for demodulating multipath signals, received from a plurality of cells, in a plurality of fingers, the method comprising the steps of: acquiring mapping information, indicating the plurality of fingers mapped on a cell-by-cell basis, and demodulation information and demodulation timing information managed on the cell-by-cell basis for the plurality of cells; grouping the plurality of fingers on the cell-by-cell basis according to the mapping information; providing demodulation information for an associated cell to each of the grouped fingers on the cell-by-cell basis; demodulating a signal received from the associated cell in the grouped fingers using the demodulation information for the associated cell; and managing the cell-by-cell demodulation timings of the grouped fingers according to the demodulation timing information using a system frame number (SFN) and a connection frame number (CFN).
