REMOTE RADIO EQUIPMENT

摘要

An RRH includes a power supply device, an AISG interface, a PA, and a control unit. The PA is operated by a power source with a first voltage or a second voltage that is lower than the first voltage and amplifies a transmission signal. The AISG interface is connected to an antenna control device operated by the power source with the second voltage. The power supply device supplies the power source to the PA and the power source to the antenna control device to the AISG interface. When the antenna control device is operated, the control unit controls such that the power supply device generates the power source with the second voltage, supplies the generated power source to the PA and the antenna control device, and increase power of the transmission signal output from the PA that is operated by the power source with the second voltage.

主权项

1. A remote radio equipment comprising:
a power amplifier that is operated by a power source with a first voltage or with a second voltage that is lower than the first voltage and that amplifies a transmission signal; an apparatus interface that is connected to an external apparatus that is operated by the power source with the second voltage; a power supply device that supplies the power source to the power amplifier and that also supplies the power source to the external apparatus via the apparatus interface; and a control unit that controls, when the external apparatus is operated, the power supply device to generate, in common, the power source with the second voltage with respect to the power amplifier and the external apparatus, supply the generated power source with the second voltage to the power amplifier and the external apparatus, and increase power of the transmission signal that is output from the power amplifier operated by the power source with the second voltage.
