METHOD FOR SWITCHING A MODE IN A MOBILE COMMUNICATION SYSTEM SUPPORTING A MULTIPLE DUPLEX MODE, PARTICULARLY FOR SIMPLIFYING A CONTROL OPERATION BY PERFORMING A TDD/FDD MODE SWITCHING OPERATION AND A HANDOVER OPERATION THROUGH ONE PROCEDURE

摘要

PURPOSE: A method for switching a mode in a mobile communication system supporting a multiple duplex mode are provided to perform a TDD/FDD mode switching operation regardless of an adjacent cell according to the transmission power of a terminal in a mobile communication system.;CONSTITUTION: A base station broadcasts a handover parameter and the information necessary for TDD(Time Division Duplexing)/FDD(Frequency Division Duplex) mode switching(300), and controls the transmission power of a terminal in consideration of channel quality of the terminal. The terminal requests the FDD/TDD mode switching by comparing a transmission power line critical value for the TDD mode switching with a transmission power line critical value for the FDD mode switching(310).;COPYRIGHT KIPO 2011
