  • Patent number: 9609691
    Abstract: 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.

  • Patent number: 8532582
    Abstract: A first communication device determines whether a remaining amount of a buffer that stores therein information included in reception data is equal to or less than a predetermined amount, and inserts, upon being determined that the remaining amount of the buffer is equal to or less than the predetermined amount, a transmission control signal for controlling data transmission performed by a second communication device into an idle section of data transmitted to the second communication device. The data includes a data section with information and the idle section without information. The data into which the transmission control signal is inserted is transmitted to the second communication device. The second communication device receiving the data, detects the transmission control signal in the idle section of the data and controls the data transmission based on the detected transmission control signal.
