    Abstract: The present application relates to a method of generating a downlink frame. The method of generating the downlink frame includes: generating a first short sequence and a second short sequence indicating cell group information; generating a first scrambling sequence and a second scrambling sequence determined by the primary synchronization signal; generating a third scrambling sequence determined by the first short sequence and a fourth scrambling sequence determined by the second short sequence; scrambling the short sequences with the respective scrambling sequences; and mapping the secondary synchronization signal that includes the first short sequence scrambled with the first scrambling sequence, the second short sequence scrambled with the second scrambling sequence and the third scrambling sequence, the second short sequence scrambled with the first scrambling sequence and the first short sequence scrambled by the second scrambling sequence and the fourth scrambling sequence to a frequency domain.

    Abstract: 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.
