Radio receiving apparatus, radio transmission apparatus, and communication method

A radio transmission apparatus that performs multi-user transmission with a plurality of radio receiving apparatuses, the radio transmission apparatus comprising:

• a reception circuit that receives a frame including a function of performing carrier sense and information associated with the multi-user transmission, and
• a transmission circuit that causes the radio receiving apparatus to participate in the multi-user transmission, based on the information associated with the multi-user transmission,
• wherein the information associated with the multi-user transmission is one-bit refuse field information included in the frame;
• the radio receiving apparatus to which the frame of setting “1” in the refuse field information, indicating that participating in the multi-user transmission is refused is transmitted, is not made to participate in the multi-user transmission;
• and the transmission circuit transmits a beacon frame including information indicating that the reception circuit enables receiving of the refuse field information.

A communication method of a radio receiving apparatus performing communication with a radio transmission apparatus that performs multi-user transmission with a plurality of radio receiving apparatuses, the method comprising the steps of:

• performing carrier sense;
• and
• transmitting a frame including information associated with the multi-user transmission,
• wherein the information associated with a function is one-bit refuse field information included in the frame;
• when refusing the participating in the multi-user transmission, “1” is set in the refuse field;
• and
• when not refusing the participating in the multi-user transmission, “0” is set in the refuse field, the method further comprising the steps of:
• transmitting the frame, when the radio transmission apparatus enables receiving of the refuse field information;
• and
• acquiring information indicating whether or not the radio transmission apparatus enables receiving of the refuse field information, from a beacon frame transmitted by the radio transmission apparatus.
