MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202647086121 A) filed by Qualcomm Incorporated on July 14, 2026, for Determining Target Relative Clock Offset For Ultra-Wideband (uwb) Positioning.
Inventors include Reddy, Varun Amar; Damnjanovic, Aleksandar; and Mukkavilli, Krishna Kiran.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: Techniques for wireless communication, where an initiator device (902) transmits a ranging initiation message and a ranging final message to a plurality of responder devices (906). The initiator device (902) determines a target relative clock offset between a target responder device of a first subset of the plurality of responder devices (906) and the initiator device (902) based on one or more reference responder devices of a second subset of the plurality of responder devices (906), the first subset of the plurality of responder devices (906) having successful reception of either the ranging initiation message or the ranging final message, and the second subset of the plurality of responder devices (906) having successful reception of the ranging initiation message and the ranging final message. The initiator device (902) determines a time of flight based on one or more time of flight measurements and the target relative clock offset.
