Abstract: A paging indicator transmission method for a mobile communication system includes the following steps. In step S1, a set of terminals are paged by grouping paging indicators, and paging indicators PCH of the terminals are carried by paging indicator channels PICH. The paging indicator channel PICH of each cell utilizes the same burst structure, and the paging indicators PCH are located at known locations at one side or two sides of a training sequence and are coded by repeated coding. In step S2, the terminal controls its RF component to receive data. The received data includes the training sequence in the timeslot where the paging indicator channel PICH is located, one or two paging indicators corresponding to the terminal, and data between the training sequence and the one or two paging indicators corresponding to the terminal.

Abstract: A cell search method is applied to a wireless system for cell search synchronization. Frame signals of the wireless system include a first sub-frame and a second sub-frame. Both of the first and second sub-frames include a first regular timeslot and a down pilot timeslot. It is determined whether a length of an actual synchronization window is smaller than a length of the first synchronization search window that is a sum of a length of the first-sub frame and a length the first regular timeslot and the down pilot of the second sub-frame. When the length of the actual synchronization search window is smaller, at least a part of data carried in the first regular timeslot and the down pilot timeslot of the second sub-frame or the first sub-frame is duplicated to before or after the actual synchronization search window.
