Abstract
An inter-node ranging method includes a first node that sends a plurality of first sequences to a second node; the first node receives a plurality of second delayed sequences from the second node; the first node determines a first phase difference between the first sequences and the second delayed sequences; and the first node determines a distance between the first node and the second node based on the first phase difference.
Claims20
A method implemented by a first node, wherein the method comprises:
- sending, to a second node, first sequences;
- receiving, from the second node in response to the first sequences, second delayed sequences;
- determining a first phase difference between the first sequences and the second delayed sequences;
- and
- determining, based on the first phase difference, a distance between the first node and the second node.

A method implemented by a second node, wherein the method comprises:
- receiving, from a first node, first delayed sequences, wherein the first delayed sequences are based on a channel delay on first sequences;
- and
- sending, to the first node in response to the first delayed sequences, second sequences to enable the first node to determine a distance between the first node and the second node.
A first node comprising:
- a transmitter configured to send first sequences to a second node;
- a receiver configured to receive second delayed sequences from the second node in response to the first sequences;
- one or more processors coupled to the transmitter and the receiver and configured to:
- determine a phase difference between the first sequences and the second delayed sequences;
- and
- determine, based on the phase difference, a distance between the first node and the second node.
