Wireless communication method using multi-links, and wireless communication terminal using same

An access point (AP) multi-link device communicating with a non-AP multi-link device on a plurality of links, the AP multi-link device comprising:

• a transceiver;
• and
• a processor,
• wherein the processor is configured to:
• transmit, to the non-AP multi-link device, a beacon frame or a probe response frame setting a traffic identifier (TID)-to-link mapping between the AP multi-link device and the non-AP multi-link device;
• and
• perform transmission on at least one of the plurality of links according to a TID mapped to the at least one of the plurality of links,
• wherein when the beacon frame or the probe response frame sets the TID-to-Link mapping between the non-AP multi-link device and the AP multi-link device, the non-AP multi-link device is not allowed to reject the TID-to-Link mapping indicated by the beacon frame or the probe response frame.

A method for operating a non-access point (AP) multi-link device communicating with a AP multi-link device on a plurality of links, the method comprising:

• receiving a beacon frame or a probe response frame from the AP multi-link device;
• when the beacon frame or the probe response frame sets a traffic identifier (TID)-to-Link mapping between the non-AP multi-link device and the AP multi-link device, determining a TID mapped to the plurality of links according to the TID-to-Link mapping set by the beacon frame or the probe response frame;
• and
• performing transmission on at least one of the plurality of links according to a TID mapped to the at least one of the plurality of links,
• wherein when the beacon frame or the probe response frame sets the TID-to-Link mapping between the non-AP multi-link device and the AP multi-link device, the non-AP multi-link device is not allowed to reject the TID-to-Link mapping set by the beacon frame or the probe response frame.
