The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: Techniques pertaining to ranging narrowband (NB) channel synchronization in wireless communications are described. An apparatus (e. g., an initiator) initiates a ranging session by: (1) transmitting a start-of-ranging (SOR) message and a Poll message; and (2) receiving a Response message from each of one or more responders. The SOR message provides either: (a) explicit NB ranging channel information; or (b) a range block index (RangingBlockIndex) to which a time offset field in the SOR message points.
