  • Publication number: 20210274447
    Abstract: A wireless communication apparatus supports a first scheme and a second scheme. A communication range for the second scheme is narrower than a communication range for the first scheme. Processing circuitry of the apparatus is configured to set first information and second information. If the second scheme is used, the processing circuitry sets a second level greater than a first level for the second information and sets a second power value smaller than a first power value for the first information. The first level and the first power value are used for the first scheme. The second power value is decided based on a receiving sensitivity required for a physical scheme selected by the second scheme.
