Narrowband ranging channel synchronization in wireless communications

By providing explicit NB ranging channel information or block index in the SOR message, the problem of inconsistent synchronization of narrowband ranging channels in wireless communication is solved, enabling responders to synchronize V values ​​on the same block, thereby improving ranging security and time efficiency.

Abstract

Techniques related to narrow-band (NB) channel synchronization in wireless communications are described herein. A device (e.g., an initiator) initiates a ranging session, including: (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 one of: (a) explicit NB ranging channel information; or (b) a RangingBlockIndex, with a time offset field in the SOR message pointing to the index.
