Samsung patents Wi-Fi method for direct device-to-device links

Patent drawing
Patent drawing from the official filing.

Samsung describes a way for two devices to talk directly to each other using a specific Wi-Fi mode called Enhanced Multi-Link Single Radio (EMLSR). The system lets one device tell the other it can use this mode, then picks one specific connection path to send data over, bypassing a central router.

Why it mattersThis could make direct file sharing or local device connections more efficient by optimizing how multiple Wi-Fi radios handle peer-to-peer traffic.

In the filing’s own words

Methods and apparatuses for facilitating the use of enhanced multi-link single radio (EMLSR) operation for peer-to-peer (P2P) communications between peer multi-link devices (MLDs). A first non-access point (AP) MLD comprises first stations (STAs), each comprising a transceiver configured to form a P2P link with a corresponding second STA of a second non-AP MLD, and a processor. The processor is configured to generate a capability indication message that includes a capability indication that indicates that the first non-AP MLD is capable of EMLSR mode operation for P2P communication over the P2P links. At least one of the transceivers is further configured to transmit the capability indication message to the second non-AP MLD.

What exactly they claim (claim 1)

1. A method performed by a first non-access point (AP) multi-link device (MLD), the method comprising: transitioning to an enhanced multi-link single radio (EMLSR) operation mode; selecting, from a plurality of links between the first non-AP MLD and a second non-AP MLD, a link for peer-to-peer (P2P) EMLSR frame exchanges with the second non-AP MLD; transmitting, to the second non-AP MLD, a P2P EMLSR start frame over the selected link to indicate the selection of the link for the P2P EMLSR frame exchanges; and transmitting, to the second non-AP MLD, one or more P2P EMLSR frames over the selected link.
