TEMPERATURE CONTROL AT POWER AMPLIFIER WITH TRANSCEIVER SWITCHING

摘要

A wireless communication device includes: a first communications unit configured to communicate with a first communication network; a second communications unit configured to communicate with a second communication network; a control unit configured to control operation of the wireless communication device; and one or more temperature sensors configured to sense operating temperatures of the first communications unit and the second communications unit and provide temperature signals to the control unit. In response to a determination that an operating temperature of the first communications unit conducting a first call exceeds a predetermined threshold temperature and an operating temperature of the second communications unit does not exceed the predetermined threshold temperature, the control unit is configured to cause the first call on the first communications unit to be switched from a first transceiver chain in the first communications unit to a second transceiver chain in the second communications unit.

1. A wireless communication device, comprising:
a first communications unit configured to communicate with a first communication network; a second communications unit configured to communicate with a second communication network; a control unit configured to control operation of the wireless communication device; and one or more temperature sensors configured to sense an operating temperature of the first communications unit and an operating temperature of the second communications unit and provide temperature signals to the control unit, wherein in response to a determination that the operating temperature of the first communications unit conducting a first call in process exceeds a predetermined temperature threshold and the operating temperature of the second communications unit does not exceed the predetermined temperature threshold, the control unit is configured to cause the first call in process on the first communications unit to be switched from a first transceiver chain in the first communications unit to a second transceiver chain in the second communications unit.
