摘要： A method of searching a cell in a mobile station of a communication system in which a plurality of cells are grouped into a plurality of cell groups, each cell group including at least two cells, includes: detecting a primary synchronization signal and a secondary synchronization signal from a received signal; and identifying a cell based on a combination of the primary synchronization signal and the secondary synchronization signal. The secondary synchronization signal is related to the cell group to which the mobile station belongs and the primary synchronization signal is related to the cell to which the mobile station belongs within the cell group.

摘要： Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

摘要： A method for tracking a user's gaze point using a mobile terminal is provided. The method includes detecting the user's eye area from a camera that is mounted in the mobile terminal and selecting reference points of the eye area, detecting a pupil corresponding to an interest area that is obtained from the reference points, generating a first virtual grid of the eye area using a pickup image of a gaze point of the pupil corresponding to each corner of the display and generating a second virtual grid having the same division areas as those of the first virtual grid in the display, and mapping a position of the pupil within the second virtual grid area corresponding to a position of the pupil within the first virtual grid.
