1. A method for determining a heading angle of a user terminal in a Wireless Local Area Network (WLAN) system, the method comprising:
- determining whether a rotation of a user is detected;
upon detecting the rotation, identifying a movement direction vector at a time when the rotation is detected; and
identifying the heading angle using the movement direction vector at the time when the rotation is detected.

Abstract
A method determines a heading angle of a user terminal in a Wireless Local Area Network (WLAN) system. The method includes examining whether a rotation of a user is detected, upon detecting the rotation, attaining a movement direction vector at a time when the rotation is detected, and attaining the heading angle by using the movement direction vector at the time when the rotation is detected.

11. An apparatus of a user terminal for determining a heading angle in a Wireless Local Area Network (WLAN) system, the apparatus comprising:
-
a modem configured to communicate with another node; a controller configured to identify whether a rotation of a user is detected using the modem, identify a movement direction vector at a time when the rotation is detected upon detecting the rotation, and identify the heading angle using the movement direction vector at the time when the rotation is detected; and a storage unit configured to store a signal strength based on a distance from reference points and a signal strength depending on a distance from an Access Point (AP). - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
