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.
Claims20
A method, comprising:
- initiating, by an initiator, a ranging session by:
- transmitting a start-of-ranging (SOR) message and a Poll message;
- and
- receiving a Response message from each of one or more responders,
- wherein the SOR message provides either:
- explicit narrowband (NB) ranging channel information;
- or
- a range block index (RangingBlockIndex) to which a time offset field in the SOR message points.
A method, comprising:
- participating, by a responder, in a ranging session by:
- receiving a start-of-ranging (SOR) message and a Poll message from an initiator;
- and
- transmitting a Response message responsive to the received Poll message,
- wherein the SOR message provides either:
- explicit narrowband (NB) ranging channel information;
- or
- a range block index (RangingBlockIndex) to which a time offset field in the SOR message points.
An apparatus implementable in a responder, comprising:
- a transceiver configured to communicate wirelessly;
- and
- a processor coupled to the transceiver and configured to perform operations comprising:
- participating, via the transceiver, in a ranging session by:
- receiving a start-of-ranging (SOR) message and a Poll message from an initiator;
- and
- transmitting a Response message responsive to the received Poll message, wherein the SOR message provides either:
- explicit narrowband (NB) ranging channel information;
- or
- a range block index (RangingBlockIndex) to which a time offset field in the SOR message points.
