1. A communication device, comprising:
circuitry configured to:
perform coordinated transmission of data simultaneously from a plurality of transmission-side communication devices to a reception-side communication device, wherein the plurality of transmission-side communication devices includes the communication device;
generate a request signal that includes coordinated transmission information and acknowledgement return information, wherein
the coordinated transmission information is regarding the coordinated transmission,
the coordinated transmission information includes common information shared by each of the plurality of transmission-side communication devices,
the common information includes a bit to identify specific information to perform the coordinated transmission,
the acknowledgement return information is information to simultaneously return an acknowledgement to the plurality of transmission-side communication devices,
the acknowledgement return information includes unique information that is unique to each of the plurality of transmission-side communication devices, and
the acknowledgement is associated with the coordinately transmitted data;
transmit the generated request signal to the reception-side communication device; and
receive, based on the transmitted request signal, an acknowledgement signal including the acknowledgement, wherein
the acknowledgement signal is transmitted simultaneously to each of the plurality of transmission-side communication devices from the reception-side communication device that has received the request signal.
