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.

Abstract: A communication device includes: a communication unit that, while wirelessly communicating in a first communication mode using a first resource of a predetermined frequency channel, wirelessly communicates in a second communication mode in which a lower delay is required than in the first communication mode using a second resource at least partially overlapping the first resource on a frequency axis and a time axis; and a notification unit that notifies a reception destination in the first communication mode, of the second resource.

Abstract: A communication device includes: a communication unit that is allowed to simultaneously perform data transmission and data reception by using a same band; an acquisition unit that acquires information regarding self-interference generated at a time when the data transmission and the data reception are simultaneously performed by using the same band; and a communication control unit that performs control regarding the data transmission based on information regarding the self-interference or information from another device generated based on the information regarding the self-interference.
