Abstract: A communication device includes a transmission unit and a notification unit. The transmission unit transmits a second signal (for example, an URLLC signal) that requires low latency severer than a first signal (for example, an eMBB signal). When the transmission unit transmits the second signal (for example, the URLLC signal), the notification unit notifies another communication device (interfering station) that transmits the first signal (for example, the eMBB signal) of a request signal containing information requesting suppression of transmission power of the first signal (for example, the eMBB signal). As a result, it is possible to satisfy a requirement of a communication mode requiring low latency.
