PROBLEM TO BE SOLVED: To provide a communication method and a mobile machine capable of surely performing handover. SOLUTION: Data is received from eNB201 by using an antenna 102 and an antenna 103 provided in a mobile communication terminal 100. When during receiving, that electric power is reduced is detected, when its data are received, instruction is performed for switching a communication method of eNB202 to a transmission method by transmission diversity. The eNB201 performs transmission by the transmission diversity based on its indication, and the mobile communication terminal 100 receives the transmitted data by a single receiving method of using only the antenna 102. Handover processing is performed by using a cell search by using an empty antenna 103. COPYRIGHT: (C)2009,JPO&INPIT
