Communication device and communication method

A communication device, comprising:

• one or more circuits configured to perform communication of a frame,
• wherein the one or more circuits are configured to
• receive a transmission acknowledgment request frame for a transmission acknowledgment response frame including frequency allocation information specifying a transmission frequency of the transmission acknowledgment response frame, and
• transmit the transmission acknowledgment response frame on the basis of the frequency allocation information, the transmission acknowledgement response frame being transmitted in response to the transmission acknowledgement request frame being received that selectively identifies the communication device for replying with the transmission acknowledgement request frame, and
• the transmission acknowledgment response frame undergoes frequency division multiplexing wherein the frequency allocation information includes information specifying a bandwidth of the transmission frequency.

A communication method, comprising:

• receiving, by a communication unit configured to perform communication of a frame, a transmission acknowledgment request frame for a transmission acknowledgment response frame including frequency allocation information specifying a transmission frequency of the transmission acknowledgment response frame;
• and
• transmitting the transmission acknowledgment response frame on the basis of the frequency allocation information, the transmission acknowledgement response frame being transmitted in response to the transmission acknowledgement request frame being received that selectively identifies the communication device for replying with the transmission acknowledgement request frame,
• wherein the transmission acknowledgment response frame undergoes frequency division multiplexing, and wherein the frequency allocation information includes information specifying a bandwidth of the transmission frequency.
