ABSTRACT:
A method of controlling uplink transmission of a user equipment in a soft handover mode in a wireless communication system comprises communicating with a first network and a second network, at a first transmission mode comprising a first transmission power level and a first data rate. The method also comprises receiving a first change command from the second network to change the first transmission mode to a second transmission mode, wherein the second transmission mode comprises a second transmission power level and a second data rate. The method also comprises entering the second transmission mode. The method also comprises maintaining the second transmission mode for a predetermined time period regardless of a second change command from the first network to increase at least one of transmission power level and data rate of the user equipment.
