Publication number: 20080096602Abstract: The present invention discloses a method and system for enabling efficient reduction of TFCs in the TFCS to achieve desired transmission, while remaining within desired power and data requirements. Upon the UE transmission power requirement exceeding the maximum or allowable transmission power the MAC shall be informed for subsequent TFC selection of all TFCs that currently exceed this limit. The UE will then chose the TFC with the next lower transmission power requirement and the sequence will continue until an acceptable TFC is determined. The present invention also enables the replacement of the TFCs in the TFCS and advanced determination of non-supported TFCS. The TFCs that require transmission power greater then the maximum or allowed UE transmission power shall be determined continuously in every TTI, not just in TTIs where the maximum power has been exceeded.Type: ApplicationFiled: December 19, 2007Publication date: April 24, 2008Applicant: INTERDIGITAL TECHNOLOGY CORPORATIONInventors: Stephen Terry, Robert DiFazio, Stephen Dick, Joseph Levy

Publication number: 20080096604Abstract: A mobile telephone device capable of acquiring a high sensitivity over a wide band without being obstructed by the antenna when in use and while being held by the hand of a user. In this device, a variable tuning circuit (106) and a band switching circuit (107) are connected with a loop element (104) acting as a TV receiving on-board antenna. The variable tuning circuit (106) is controlled with a tuning voltage (110) generated in a TV receiving circuit (109). A channel control unit (111) sets the received channel of the TV receiving circuit (109) and controls the band switching circuit (107) with a band switching signal (112).Type: ApplicationFiled: June 22, 2005Publication date: April 24, 2008Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Yukari Yamazaki, Yutaka Saito, Yoshio Koyanagi, Kiyoshi Egawa, Hiroyuki Sasaki

Publication number: 20080096610Abstract: A method for inputting text in a mobile terminal having a touch screen is provided. When detecting a touch-down, the mobile terminal displays a character of the touch-down point and nearby characters in an enlarged size and indicates the character of the touch-down point in the enlarged display. When a drag event occurs before a touch-up event, the mobile terminal determines the dragging distance and direction, changes the touch-down point to a new location according to the dragging distance and direction, and indicates another character at the new location. When a touch-up event occurs at the new location, the mobile terminal then inputs the other character indicated at the new location.Type: ApplicationFiled: October 19, 2007Publication date: April 24, 2008Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Keun-Ho SHIN, Kurgi Eduard, Sung-Wook Kang
