Abstract
The disclosure provides a method for facilitating timing synchronization in a network. The method comprises, at a network node: updating a timing value of the network node iteratively based on synchronization signals from neighboring network nodes; determining that the timing value is in a stable state; calculating a bias due to propagation delays of the synchronization signals based on a number of timing values obtained in iterations of said updating; and correcting the timing value based on the bias.

A method for facilitating timing synchronization in a network, comprising, at a network node:
- updating a timing value of the network node iteratively based on synchronization signals from neighboring network nodes;
- determining that the timing value is in a stable state;
- calculating a bias due to propagation delays of the synchronization signals based on a number of timing values obtained in iterations of said updating;
- and
- correcting the timing value based on the bias.
A network node for facilitating timing synchronization in a network, comprising:
- an updating unit configured to update a timing value of the network node iteratively based on synchronization signals from neighboring network nodes;
- a determining unit configured to determine that the timing value is in a stable state;
- a calculating unit configured to calculate a bias due to propagation delays of the synchronization signals based on a number of timing values obtained in iterations of said updating;
- and
- a correcting unit configured to correct the timing value based on the bias.
A non-transitory machine-readable storage medium that provides instructions, which when executed by a processor of a network node, cause said processor to perform operations comprising:
- updating a timing value of the network node iteratively based on synchronization signals from neighboring network nodes;
- determining that the timing value is in a stable state;
- calculating a bias due to propagation delays of the synchronization signals based on a number of timing values obtained in iterations of said updating;
- and
- correcting the timing value based on the bias.
