Abstract: There is provided a communication method for a coordinator communication device, including generating a first scheduling element to be used by a first communication device and a second scheduling element to be used by a second communication device; and transmitting the first and second scheduling elements to the first and second communication devices. The second scheduling element includes a second allocation indicating a time-frequency resource allocated to the second communication device. The first scheduling element includes a first allocation indicating a time-frequency resource allocated to the first communication device and optionally includes a first virtual allocation that is a duplicate of the second allocation. The first communication device performs communication in accordance with a first communication system using a first frequency band, and the second communication device performs communication in accordance with the first communication system or a second communication system using a second frequency band that includes the first frequency band.
