Abstract: An apparatus and method for displaying menu items of a hierarchical menu on a screen in such a manner that a function desired by a user can be traced and performed with a minimum number of key inputs. The top-level menu and bottom-level menu of the hierarchical menu can be simultaneously displayed in one screen picture, thereby enabling a user to reach from an upper-level menu to the bottom-level menu or from the bottom-level menu to the top-level menu with a minimum number of key inputs without passing through intermediate-level menus. Further, a certain menu can be displayed in one screen picture along with the one-level upper menu and one-level lower menu thereof or the one-level lower menu thereof so that the user can readily recognize the position of a current menu. Furthermore, the user can access all menus using only direction keys.

Abstract: A method and a multimode terminal for minimizing current consumption and simultaneously reducing a handover processing time when a handover occurs between communication networks which provide communication services using different mobile communication technologies. The communication network modems of the multimode terminal are interconnected via a one-to-one communication path, so that a handover target communication network modem is powered on only when handover actually occurs. In this way, by efficiently determining a time point when the handover target communication network modem is powered on, a processing time according to the occurrence of handover can be reduced, and additional current consumption can be minimized.

Abstract: An adaptive subchannel and bit allocation method in a wireless communication system. A mobile station analyzes channel quality information of a subchannel at a predetermined period and determines a feedback band index with a maximum decision criterion. The mobile station feeds back the determined feedback band index with the maximum decision criterion to a base station. The base station generates band allocation information using the feedback information from the mobile station, and transmits the band allocation information to the mobile station. The mobile station transmits AMC information using the band allocation information received from the base station. The base station estimates a channel using the AMC information transmitted from the mobile station and allocates bits to the allocated band according to the channel estimation result.
