The base station comprises a transmitter configured to transmit, to the radio terminal, configuration information for frequency hopping where the radio communication is performed while switching the narrow frequency band; and a controller configured to allocate, to the radio terminal, a first frequency band of the frequency hopping and a frequency band of a hopping destination. The first frequency band and the frequency band of the hopping destination respectively include the narrow frequency band and fraction resource blocks. The fraction resource blocks are resource blocks, the number of which is smaller than the predetermined resource block number.

  • Patent number: 11107396
    Abstract: Objects are to provide a display device the power consumption of which is reduced, to provide a self-luminous display device the power consumption of which is reduced and which is capable of long-term use in a dark place. A circuit is formed using a thin film transistor in which a highly-purified oxide semiconductor is used and a pixel can keep a certain state (a state in which a video signal has been written). As a result, even in the case of displaying a still image, stable operation is easily performed. In addition, an operation interval of a driver circuit can be extended, which results in a reduction in power consumption of a display device. Moreover, a light-storing material is used in a pixel portion of a self-luminous display device to store light, whereby the display device can be used in a dark place for a long time.
