Samsung patents Wi-Fi method to sync device discovery with network time

Patent drawing
Patent drawing from the official filing.

This filing describes a way for a device to coordinate its Wi-Fi network connection and its ability to find nearby devices. It uses the longest time gap between network signals from two different Wi-Fi routers to set a shared schedule for when devices look for each other.

Why it mattersIt helps devices find each other more reliably when they are connected to different Wi-Fi networks, which could improve how phones and laptops share files or connect to local services.

In the filing’s own words

A first station for performing Wi-Fi aware communication, according to one embodiment of the present disclosure, may receive at least one first beacon in a first access point (AP) period communicating with a first AP. Further, a wireless station may communicate with a second wireless station in a first aware period in which Wi-Fi aware communication is performed. According to one embodiment, the first AP period and the first aware period are determined by a maximum AP beacon interval (imax), and the maximum AP beacon interval (imax) may be determined by the larger of a first interval of the first beacon transmitted by the first AP and a second interval of a second beacon transmitted by a second AP connected with the second wireless station.

What exactly they claim (claim 1)

1. A first station configured to perform neighbor awareness networking (NAN)-based communication and wireless local area network (WLAN) communication, the first station comprising: a transceiver; and at least one processor coupled to the transceiver, wherein the at least one processor is configured to: receive at least one first beacon in a first access point (AP) period in which the first station communicates with a first AP; and communicate with a second station in a first aware period in which the first station performs NAN-based communication, wherein the first AP period and the first aware period are determined based on a maximum AP beacon interval (i max), and wherein the maximum AP beacon interval (i max) is determined by a larger one of a first interval of the at least one first beacon transmitted by the first AP and a second interval of a second beacon transmitted by a second AP associated with the second station.
