Transmitting station and receiving station

A transmitting station that is a station that transmits wireless signals, the transmitting station comprising:

• a first wireless signal processing circuit configured to transmit wireless signals including first data, using a first channel;
• a second wireless signal processing circuit configured to transmit wireless signals including second data, using a second channel that is different from the first channel;
• and
• a processor that manages a link state of the first wireless signal processing circuit and a link state of the second wireless signal processing circuit,
• wherein the processor
• imparts, in a case in which a multilink is established with a receiving station and wireless signals are to be transmitted using the multilink, first multilink information and identification information to the first data and the second data without dividing each of the first data and the second data, the first multilink information indicating use of the multilink, the identification information indicating an order of the first data and the second data, the first data being data which is input to the processor and to which a first header is imparted, the second data being data which is input to the processor and to which a second header different from the first header is imparted, the first multilink information and the identification information being imparted to each of the first header and the second header,
• imparts, in a case in which the multilink has not been established with the receiving station or transmission is not to be performed using the multilink, second multilink information to the first header of the first data or the second header of the second data, the second multilink information not indicating the use of the multilink,
• outputs, in a case in which the first multilink information is imparted, the first data and the second data, to which the first multilink information and the identification information are imparted, to one of the first wireless signal processing circuit and the second wireless signal processing circuit, in an order of input, and
• outputs, in a case in which the second multilink information is imparted, the first data or the second data, to which the second multilink information is imparted, to one of the first wireless signal processing circuit and the second wireless signal processing circuit,
• wherein the first and second headers are extended media access control (MAC) headers.
