TIME SYNCHRONIZATION OVER A WIRELESS NETWORK FOR LATENCY-SENSITIVE TRAFFIC - A simplified explanation of the abstract

• This abstract for appeared for patent application number 17717791 Titled 'TIME SYNCHRONIZATION OVER A WIRELESS NETWORK FOR LATENCY-SENSITIVE TRAFFIC'

Simplified Explanation

This disclosure presents systems and methods for synchronizing wireless devices with each other. It describes a process where a device sends a signal to a wireless station, indicating an enhanced synchronization mode on a specific communication link associated with an access point. During this enhanced synchronization mode, the device sends multiple sync frames on the communication link more frequently than the predetermined Target Beacon Transmission Times (TBTTs). Each sync frame indicates the timing synchronization offset between the first access point and a second access point of the device. One of these sync frames may be a Fast Initial Link Setup (FILS) Discovery frame that carries the timing synchronization function (TSF) value of the first access point.

Original Abstract Submitted

This disclosure provides systems and methods for synchronizing wireless devices with each other. In some implementations, a device transmits, to at least one wireless station (STA), an indication of an enhanced synchronization mode on a first communication link associated with a first access point (AP) of the device. The device transmits, during the enhanced synchronization mode, a plurality of sync frames on the first communication link more often than Target Beacon Transmission Times (TBTTs) associated with the first communication link, each of the plurality of sync frames indicating a Timing Synchronization Function (TSF) offset between the first AP and a second AP of the device. In some instances, at least one of the plurality of sync frames may be a Fast Initial Link Setup (FILS) Discovery frame carrying a TSF value of the first AP.
