AI summary

A communication device performs, based on a frequency resource that is to be allocated to communication of a first other communication device in accordance with a first communication standard, frequency resource allocation for communication of a second other communication device that conforms to a second communication standard. In the frequency resource allocation, in a case where the first other communication device and the second other communication device concurrently communicate with the communication device, a distribution of a first frequency resource to be allocated for communication using the first communication standard and a second frequency resource to be allocated for communication using the second communication standard in an available frequency band is determined, and a frequency resource included in the second frequency resource is allocated to the second other communication device.
