1. A wireless communication device which communicates with first terminals compliant with a first standard, second terminals compliant with a second standard and third terminals compliant with a third standard within a communication group formed by the wireless communication device, comprising:
transmitting circuitry configured to transmit a first frame that is a MAC (Medium Access Control) frame to the first terminals, the second terminals and the third terminals, wherein
the first frame is a frame for notification of operation information of the communication group and the first frame includes a first field, and at least one of a second field or a third field,
the first field is configured to include a first identifier of the first field and first information related to a first bandwidth used by the first terminals,
the second field is configured to include a second identifier of the second field and second information used in combination with the first information, a combination of the first information and the second information designates a second bandwidth used by the second terminals if the second field is present, and the second bandwidth is designated by the first field otherwise, the third field is configured to include a third identifier of the third field and third information used in combination with the first information, a combination of the first information and the third information designates a third bandwidth used by the third terminals if the third field is present, and the third bandwidth is designated by a combination of the first information and the second information otherwise; and
controlling circuitry configured to control the transmitting circuitry,
wherein
a maximum bandwidth that can be transmitted by the first terminals is the first bandwidth, a maximum bandwidth that can be transmitted by the second terminals is the second bandwidth and a maximum bandwidth that can be transmitted by the third terminals is the third bandwidth,
wherein the transmitting circuitry is configured to
transmit a second frame to at least one of the first terminals or the second terminals via at least one first channel which is included in the first bandwidth or the second bandwidth after the first bandwidth or the second bandwidth is designated to the at least one of the first terminals or the second terminals, and
transmit a third frame to at least one of the third terminals via at least one second channel which is included in the third bandwidth after the third bandwidth is designated to the at least one of the third terminals,
wherein the second frame and the third frame are transmitted in a frequency multiplexing, and
wherein the at least one second channel is different from the at least one first channel.
