1. A communication device capable of connecting to and communicating with another device using a first function operating as a terminal device and a second function operating as a base station device, the communication device comprising:
one or more processors; and
one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the one or more processors to:
acquire a first reception power density of a signal of a downlink received from an upstream device connected by the first function, and acquire a second reception power density of a signal of an uplink received from a downstream device connected by the second function;
transmit a transmission power control command for controlling transmission power of the signal of the downlink to the upstream device, based on the first reception power density and the second reception power density; and
transmit a transmission power control command for controlling transmission power of the signal of the uplink to the downstream device, based on the first reception power density and the second reception power density,
wherein, if a value obtained by subtracting the second reception power density from the first reception power density exceeds a first value, at least one of transmission of a transmission power control command instructing to decrease the transmission power of the signal of the downlink to the upstream device or transmission of a transmission power control command instructing to increase the transmission power of the signal of the uplink to the downstream device is executed.
