US 2026/0101313 A1 · COMMUNICATION METHOD AND RELATED DEVICE

Abstract

The present application describes a communication method and related device. The method includes a first responder receiving from an initiator a first frame for initiating a ranging process. The first responder generates a first private address based on the first frame and information related to an identity of the first responder, and the first responder transmits a second frame carrying the first private address to the initiator. The method may be applied to ultra-wideband multi-millisecond ranging systems. According to this application, an initiator can verify whether a frame is really from an authorized responder in an ultra-wideband multi-millisecond ranging session.
