Abstract
A method for dual mode mobile terminal in an MIMO wireless communication system is disclosed. The present invention includes the steps of if an uplink transmission mode is for simultaneous transmission to an LTE base station and a CDMA base station, determining whether a transmission power to the LTE base station is equal to or greater than a threshold value, transmitting a simultaneous transmission mode dedicated scheduling request signal for excluding a risky frequency band from an uplink band to the LTE base station, receiving a scheduling information on the uplink band except the risky frequency band from the LTE base station, transmitting a CS service signal to the CDMA base station, and transmitting a PS service signal to the LTE base station using the scheduling information.
